Positive and negative electrode collector plates in the cell cases are respectively attached to the base ends of the frame fittings. End frame fittings that have base ends and protruding portions for cell cases are located at both outer ends of the rechargeable battery for connecting the cell cases to outside terminals. Connection terminals that have protruding portions are connected to the end frame fittings at both outer ends of the rechargeable battery.

A liquid container has a movable member which defines a liquid containing space and which is displaced as the liquid is supplied, a valve for allowing a gas to be introduced into the containing space from the outside and for preventing the liquid from being extracted from the containing space to the outside, and an introduction channel for coupling the valve and the containing space to guide the introduced gas into the containing space. An intake port of the introduction channel located on the containing space side is positioned in an upper part of the containing space in an orientation in use. A negative pressure is kept substantially constant to consume the liquid completely. Since the air introduction for keeping the negative pressure at an adequate value is carried out in a region in a gaseous phase in the container, no leakage of ink occurs, and air is reliably introduced.

The endcover assembly for a combustor includes an endcover having an aperture, an insert disposed in the stepped bore opening through an internal face of the endcover, a fuel cartridge extending through the insert and aperture and a seal cover on the external face of the endcover. Seal cover / endcover annular seals are disposed in registering axial cavities to seal against fluid leakage externally of the endcover assembly. Generally C-shaped and W-shaped seals are disposed in the cavities between the stepped shoulders of the insert and aperture to seal against leakage through the internal face of the endcover. The seals maintain sealing engagement during assembly and thermal distortion during turbine usage.

Low-pressure drop thermal assemblies, systems and methods of making low-pressure drop thermal assemblies for use in high power flux situations. A manifold body is attached to a distributor to form a subassembly. This subassembly is in communication with a substrate surface, which has a semiconductor device in need of thermal management thereon. An enclosed cavity is formed between the target substrate surface and the subassembly, and a seal of the cavity protects critical components residing on the active surface of the semiconductor device. The distributor includes a distributed liquid impingement microjet inlet array isolated from and parallel with a distributed microjet drain array for impinging cooling fluid and removing spent heated fluid in a direction orthogonal to a target surface for maximizing the heat transfer rate, and thereby providing high cooling flux capabilities while enabling low-pressure drops.

To provide a flow cell that is free from liquid leakage and excels in chemical resistance. There is provided a preferred form of flow cell comprising flat-plate glass substrate (3); adherent fluororesin sheet (5) having a groove as flow channel (7) made by cutting machining; and glass substrate (1) as lid member furnished with through-holes (9, 11) as fluid inlet and outlet at positions corresponding to both end portions of the groove. The fluororesin sheet (5) is interposed between the glass substrates (1, 3) and, while heating at a temperature not lower than the melting point of the fluororesin sheet (5), pressurized so that the glass substrates (1, 3) are bonded together by the fluororesin sheet (5) per se. Flow channel member (17) is constructed by the glass substrate (3) and, bonded thereonto, the fluororesin sheet (5).

A band coupling for straight line interconnection of flangeless pipes and a built in pipe grip mechanism to resist axial separation forces is provided. The band-clamp coupling comprises an outer housing of cross-section resembling a wide, low-wall channel, the walls thereof facing the center of the pipes, and a low-wall inner channel fitting into the outer channel. The inner channel being provided with spaced-apart inwardly-facing projection adjacent to each of the inner channel walls, each projection having a first sloping side axially facing the line of pipe abutment and a second sloping side axially facing away from the line of pipe abutment. A sloped internally-toothed grip washer is disposed along each of the projection second sides; and a seal member is disposed inside the inner channel and extending along the major portion of the width thereof to abut both the first sides axially facing the line of pipe abutment.

Disclosed is a portable therapeutic fluid dispensing device. The fluid dispensing device includes a reusable part (100) comprising a reusable part housing including at least a controller and a first portion (186) of a driving mechanism, and a disposable part (200) comprising a disposable part housing including at least a reservoir (220) to retain therapeutic fluid, an outlet port to which the therapeutic fluid is dispensed, a fluid conduit providing fluid communication between the reservoir and the outlet port, and a second portion (112) of the driving mechanism. At least a portion of the disposable part housing defines at least a portion of the reservoir. Also, the second portion of the driving mechanism is mechanically couplable to the first portion of the driving mechanism upon connection of the disposable part to the reusable part.

A filter cartridge and spool valve manifold assembly includes a filter cartridge and a spool valve manifold. The filter cartridge includes a filter element and inlet / outlet portion in fluid communication with the filter element. The inlet / outlet portion has a cartridge inlet port and a cartridge outlet port. The spool valve manifold includes a housing and a body. The housing has a housing inlet port and a housing outlet port adapted for fluid communication with a fluid supply system. The body is located within the housing and configured to rotate around a first axis relative to the housing. The inlet / outlet portion of the filter cartridge is fluidly coupled to the body via insertion of the inlet / outlet portion into the body in a direction perpendicular to the first axis.

A rotary shaft monitoring seal system includes a seal housing; a seal assembly in the housing for sealingly engaging a rotary shaft to prevent fluid leakage between the shaft and the housing; a monitoring port in the housing; and a detector assembly mounted in the port for sensing conditions in the vicinity of the seal assembly.

A vaporizer device of cotton-free e-cigarette, comprising: an outer sleeve, a supporting frame arranged inside the outer sleeve, a vaporizer unit fixed into the supporting frame, a filter piece and a liquid percolation piece sequentially connected to one end of the supporting frame, and a fixation seat connected to other end of the supporting frame. A backflow groove is made inside the supporting frame to prevent leakage caused by the backflow of residual liquid. The filter piece is made of heat-resisting material. The liquid percolation piece is connected at one end with a liquid storage cup by snap joints. Another end of the filter piece keeps a safe distance away from the vaporizer unit to avoid being burned. The liquid storage cup and the outer sleeve are assembled to form a slit therebetween to prevent the backflow of residual liquid.

A method and system is provided to induce mild hypothermia in a patient through controlled heating of the preoptic anterior hypothalamus (POAH) in conjunction with cooling of patient's body. The system employs an ultrasound transducer that may be positioned extracorporeally to a patient skull for emitting ultrasound energy to the POAH. The ultrasound energy heats the POAH to inhibit thermoregulatory responses of the body such that a cooling means may more effectively cool bodily tissue in order to reduce a patient's core body temperature. Feedback sensors may be positioned at various locations on the patient in order to monitor the patient's core body temperature. A control apparatus included with the system controls the amount of heat the POAH receives and the amount of cooling the body receives based on the feedback signals from the sensors.
