A longitudinal minimal-invasion bone cutter for tubular bones comprises a bone cutting end bone cutting device and far end positioning devices. The bone cutting end bone cutting device is slidingly sleeved on a positioning adjusting guide rail which is in a long-strip shape, a sliding groove is arranged in the middle of the positioning adjusting guide rail along the length direction, and scales of the positioning adjusting guide rail are arranged along the sliding groove. The far end positioning devices are symmetrically sleeved at two ends of the positioning adjusting guide rail slidingly. By means of the longitudinal minimal-invasion bone cutter, medical workers can perform longitudinal bone cutting operations on the tubular bones according to treatment needs, and the longitudinal minimal-invasion bone cutter is convenient to operate. When the operations are performed, the longitudinal minimal-invasion bone cutter provides convenience for transverse traction of bone blocks and meets needs of angiitis treatment. The bone cutting operations performed by the aid of the longitudinal minimal-invasion bone cutter belong to minimal-invasion operations, do not damage nerves, blood vessels, soft tissues and periostea, have small invasion, facilitate reconstruction and union of bones, and meet needs of longitudinal traction treatment of the tubular bones. By means of the longitudinal minimal-invasion bone cutter, safety and accuracy of the longitudinal bone cutting operations of the tubular bones are improved, medical workers can conveniently perform the operations, and the operation effect is guaranteed.

A method for increasing the resonant frequency of a torsional hinged device having a reduced attaching area between the torsional hinges and the supporting anchors. The resonant frequency is increased by adding a material over the reduced area to stiffen the connection between the torsional hinges and the support anchors.

A clutch including two rotary shafts, one of which is connected to one or more first clutch plates which cooperate with a second set of clutch plates, the clutch plates acted on by an actuating piston positioned within a two chamber hydraulic cylinder. A torque control valve comprising a cylindrical inner valve member rotatably and linearly movably received in a cylindrical opening in an outer valve member. Each valve member having elongate recesses positioned such that longitudinal movement of the inner valve member within the outer valve member will vary the degree of communication between the first and second elongate recesses connected to two hydraulic fluid sources of differing pressures. The second clutch plates are connected to one side of a spring of predetermined spring rate, which is also connected to one of the valve members, and the other side of the spring is connected to the other of the valve members and to the other rotary shaft.

Pressure contact power semiconductor module comprises: base (1) and cover (2) plates; a semiconductor module (3) with first (31) and second connections (32); and a spring (4) arranged between the first connection and the cover plate. The lower connection connects the semiconductor module to the base plate, while the electrical connection to be cover plate is made via a contact strut (5) that extends through the center of the spring.

A component-incorporated wiring substrate is provided. Some embodiments include a plate-like component incorporated in a core substrate and a build-up layer having an insulation layer and a conductor layer disposed in alternating layers. The component has terminal electrodes formed at its opposite ends having a side surface and a main surface. An insulation layer disposed on the main surface of the component has via conductors formed therein which are connected to the side surfaces and the main surfaces of the respective terminal electrodes. The via conductors are tapered, such that their via diameter decreases in a direction toward the terminal electrode, and their via diameter at a position where they connect to the main surface is greater than a length of the main surface. Accordingly, the area of connection between the via conductors and the corresponding terminal electrodes is increased, improving connection reliability through enhancement of tolerance for positional deviation.

In a preferred embodiment, the invention provides a circuit and method for improving the soft error rate in a dual-port read SRAM cell. A write-only transfer device is connected to a cross-coupled latch, a first wordline, and a first bitline. A first read-only transfer device is connected to a second bitline, a second wordline, and a first pull-down device. A second read-only transfer device is connected to the first bitline, the first wordline, and a second pull-down device. A clear memory transfer device is connected to the cross-coupled latch, a third bitline, and a third pull-down device. This configuration allows a reduction in the size of a dual-port SRAM cell with little or no reduction in the read access time of the cell. The reduction in size also reduces SER by reducing the cross-sectional, p / n junction area exposed to radiation.
