In one embodiment of the present inventions, an exhaust outlet in a vacuum processing chamber includes a nonsealing flow restrictor which can facilitate rapid opening and closing of the flow restrictor in some applications. Because the flow restrictor is a nonsealing flow restrictor, the conductance of the flow restrictor in the closed position may not be zero. However, the flow restrictor can restrict the flow of an exhaust gas from the chamber to permit the retention of sufficient processing gas in the chamber to deposit a film on the substrate or otherwise react with the substrate. After a film has been deposited, typically in a thin atomic layer, the exhaust flow restrictor may be opened such that the flow restrictor conductance is significantly increased to a second, higher flow rate to facilitate exhausting residue gas from the chamber. The nonsealing flow restrictor may be closed again to deposit a second layer, typically of a different material onto the substrate. The nonsealing flow restrictor may be rapidly opened and closed to deposit alternating layers of a variety of materials onto the substrate.

The invention relates to leadless cardiac pacemakers (LBS), and elements and methods by which they affix to the heart. The invention relates particularly to a secondary fixation of leadless pacemakers which also include a primary fixation. Secondary fixation elements for LBS's may either actively engage an attachment site, or more passively engage structures within a heart chamber. Active secondary fixation elements include a tether extending from the LBS to an anchor at another site. Such sites may be either intracardial or extracardial, as on a vein through which the LBS was conveyed to the heart, the internal or external surface thereof. Passive secondary fixation elements entangle within intraventricular structure such as trabeculae carneae, thereby contributing to fixation of the LBS at the implant site.

The invention relates particularly to a secondary fixation of leadless pacemakers which also include a primary fixation. Secondary fixation elements for LBS's may passively engage structures within the heart. Some passive secondary fixation elements entangle or engage within intraventricular structure such as trabeculae carneae. Other passive secondary fixation elements may engage or snag heart structures at sites upstream from the chamber where the LBS is primarily affixed. Still other embodiments of passive secondary fixation elements may include expandable structures.

Methods and compositions for treating or preventing microbial infection in mammals with sulfated polysaccharides wherein the polysaccharides have a degree of sulfation effective to enable maximal interaction of constituent sulfate groups with the microbe which causes the infection and wherein the sulfated polysaccharide is not substantially endocytosed or degraded by cell receptor binding in the mammal and thereby retains antimicrobial activity in vivo.

A bit retention device includes a shaft having a sidewall defining a hexagonal cavity extending from a first end thereof and a ball groove extending through the sidewall and communicating with the hexagonal cavity. A ball is disposed in the ball groove and a ball spring engages the ball and biases the ball toward the first end. An actuator sleeve surrounding the shaft includes an internal ramp engaging the ball. The internal ramp includes a shallow ramp portion having a first angle of inclination with respect to a center axis and a steep ramp portion having a second angle of inclination with respect to said center axis of said shaft that is greater than the first angle of inclination. A spring biased plunger assembly is disposed in the bore for biasing a bit received in the bore in a direction toward the insertion end.

A horse boot (10) includes a shell (12) for a hoof and a gaiter (22) for the pastern. The shell has a sole (14), an upper (16), a tongue (18), and an elastic strap (60) for tightening the upper and the tongue around the hoof of a horse. The gaiter (22) is releasably attached to the upper so as to extend around the rear of the shell and can be wrapped around the pastern (P) of the horse immediately above the hoof's hairline (C) and below the fetlock to function as a barrier against the entry of debris into the shell. The gaiter provides an additional anchor to retain the shell in place under extreme conditions of use. The releasable connection to the shell (12) allows replacement of the gaiter (22) when worn out.

The invention discloses a guide plate for implantation of orthodontic micro-screw and a manufacturing method thereof. The method comprises: acquiring dental data from a CBCT image of a patient, rebuilding a three-dimensional image of jaw and teeth at an area to be subjected to implantation; acquiring a three-dimensional image of a to-be used micro-screw from a preset micro-screw three-dimensional image database, and regulating the three-dimensional image of the to-be used micro-screw at a preset position; establishing a first cylinder, enabling the direction of the cylinder to be same to the direction of the to-be used micro-screw and enabling the diameter of the cylinder to be larger than the diameter of a cuff part at the end of a screwdriver head; establishing a guiding part, namely forming a second cylinder at the periphery of the first cylinder along the axial direction, enabling the diameter of the second cylinder to be larger than the diameter of the first cylinder and enabling the two cylinders to be coaxial and same in height, and arranging a buffer distance between one end, facing to the phatnoma mucous membrane, of the cylinders and phatnoma mucous membrane; establishing a position-fixing part, namely painting the occlusion part and the occlusion surface at the appearance high point close to a tooth axial surface of the implantation part with an extended-crown preset-thickness coating; and establishing a connection part to connect the guiding part and the position-fixing part, so as to obtain a three-dimensional image of the guide plate, and printing.

An externally-powered prosthesis mechanism usable with persons with amputations at or proximal to the level of the metacarpophalangeal joint, as well as persons with high-level amputations. The prosthesis mechanism includes a grasping mechanism including a mechanically operable finger member and a mechanically operable thumb member kinematically linked to the finger member such that the grasping mechanism is disposed in respective opened and closed configurations when the finger member is respectively moved away from and toward the thumb member. The prosthesis mechanism further includes a drive system extending tangentially with respect to the grasping mechanism and including a motor operatively connected to drive at least one planetary gear stage, which is operatively connected to drive the grasping mechanism to the opened configuration when the motor is driven in a first direction and further drive the grasping mechanism to the closed configuration when the motor is driven in a second opposite direction.

The invention seeks to enable a heater or equivalent type food product to be eaten while hot and held in the hand, while retaining the heating qualities of the ingredients after heating. To do this, the invention proposes making a food product in application of the following steps: preparing uncooked dough (1) of the pizza or equivalent type, spreading it as a substantially rectangular basic slice that is twice the size of the product to be obtained; placing the various selected ingredients (7a, 7b) on the uncooked dough; cooking the dough with its ingredients in a pizza oven, on the floor and at the ambient temperature of said oven; on leaving the oven, folding the cooked and filled dough in half about a middle fold line forming a connecting spine (2) of continuous dough between two facing main faces (3a, 3b) that are substantially plane, with edges (3) of the faces being brought into alignment to define a side edge face (5) opposite from the connecting spine (2), and two end edge faces (6a, 6b), in a slice corresponding to the slice of the product that is to be obtained, and covering the side edge face and optionally no more than one of the end edge faces in an edible seam (4) for joining the edges together.

A circuit for reducing standby leakage in a memory unit contains a capacitive divider coupled to the memory unit so as to generate a voltage across the memory unit, which is adequate to retain memory values during one of a sleep state and a standby state. An inductive circuit for reducing standby leakage in a memory unit includes an inductive divider coupled to the memory unit so as to generate a voltage across the memory unit, which is adequate to retain memory values during one of a sleep state and a standby state.
