Patent EP-0137620-A2 (EP)
Inventor: KIM SUK KI
IPC: H03F3/04
Filed: 1984-08-08
Abstract: @ A high impedance is implemented in the input bias path of an integrated instrumentation amplifier by a normally on transistor switch. A signal from the output of the amplifier is used to turn the switch off to provide the requisite high impedance. Otherwise, the switch is on to provide low impedance for proper biasing. The circuit is adapted for encoded input signals such as occur in capacitive coupled credit card encoding circuits.

Abstract: A window shuttering mechanism for a cassette (1) has a shutter (8) to cover or expose a window (7) through which a recording medium of the cassette (11) is accessed. A lock pawl (12) on the shutter (8) co-operates with a recess (14) in a springy lever (13) to hold the shutter in its closed position in which the window (7) is covered. When the cassette is inserted into a player a lock release (20) presses the lever (13) to release the pawl (12) from the recess (14) but before it does so a tongue (25) of a pivoted resilient shutter closer (21) is pressed into an engagement aperture (31) in the shutter (8) due to the opposite end (28) of the shutter closer (21) being engaged by a face (30) of the cassette (1). The tongue (25) engaged in the engagement aperture (31) pulls the shutter (8) to the closed position when the cassette (1) is ejected from the player.

Abstract: A method for lining tubular structures comprises stretching a pipe, formed from thermoplastic material and having an outer diameter greater than the internal diameter of the tubular structure, to the extent that the outer diameter of the pipe is less than the internal diameter of the tube. The tube is then placed over the stretched pipe and the tension in the stretched pipe is released. The stretched pipe contracts longitudinally and expands readially against the inside of the tubular structure, thereby forming a liner. In an emodiment, the tubular structure (30) is a steel pipe and the thermoplastic pipe (20) is a polyethylene pipe. The thermoplastic pipe (20) is stretched by anchoring barbed couplers (23, 24) in the ends (21, 22) of the pipe, inserting a pushrod (27) through the coupler (23) to abut a member (26) anchored in the coupler (24), and screwing a bolt (28) into coupler (23) to abut and push the end of the pushrod (27) until the required stretching of the pipe (20) has been achieved.

Abstract: A connector assembly (10) includes a stacked linear array of an alternating sequence of terminals (12) and resiliently compressible insulator portions (14). The array is linearly compressed in an accordian-­like fashion and is inserted in a housing (24) having a cavity of length less than the uncompressed length of the array. The array is inserted in the housing and allowed to expand against opposing walls (26) of the housing thereby maintaining the terminals in a self-compensating floating arrangement. A method for forming the connector assembly includes the steps of arranging resiliently compressible dielectric material (14) between terminals (12) to form a stacked linear array, linearly compressing the stacked linear array in an accordian-like fashion, inserting the compressed array in a housing (24), and thereafter maintaining the array in linear compression within the housing.

Abstract: Transistor with submicronic gate length. For such transistors, the threshold voltage VT varies with the gate length LG, and the transfer characteristic for the drain current IDS varies little with the voltage VGS applied to the gate. To obtain a stable threshold voltage VT and an effective channel-constriction effect, the access regions to the channel must be optimised. In the transistor according to the invention, comprising, on a substrate (14), an active layer (15) and a gate (16) and two wells (17, 18) for picking up contact on the source and drain (19, 20), access to the channel (15) is optimised by at least one region (21 or 22) of gradual transition of doping level, from the n type near the channel (15) to the n<+> type near the well (17 or 18). Application to integrated logic circuits whose transistors have very close threshold voltages, and to microwave circuits comprising multipin transistors. <IMAGE>

Abstract: An intra aortic balloon device which incorporates a hemostasis sheath (50) on the balloon catheter (42) is provided. The hemostasis sheath of the invention is incorporated onto the balloon catheter during manufacture before attachment of the intra aortic balloon bladder. The hemostasis sheath is tapered from a smaller outside diameter at the point closest to the balloon bladder gradually increasing in diameter towards a larger outside diameter at the end opposite the balloon bladder. The hemostasis sheath may also have an extended tip of constant outside diameter at its proximal end (54) to faciliate insertion through the skin. 
     Additionally, a method for the percutaneous insertion of an intra aortic balloon assembly is provided. According to this method, the intra aortic balloon is inserted into the femoral common artery using the percutaneous insertion technique. One method is to employ a tear away insertion sheath as known in the art. However, if bleeding occurs when the insertion sheath is removed, according to the invention, the hemostasis sheath is slid into the insertion site to stop the bleeding. A second alternative is a method for inserting an intra-aortic balloon device into a patient without using an insertion sheath is provided.
