IPC: B31B23/00
Filed: 1997-03-17
Abstract: A thermoplastic bag structure (10) and method for making and packaging thermoplastic bags such that their tops are easily identified and the bags are easily opened. The method for producing these bags begins with cutting a flattened thermoplastic tube into two portions (16, 18).

Title: Package for semiconductor power device and method for assembling the same
Inventor: SHIMIZU TOSHIO
IPC: H01L23/24
Filed: 1998-12-07
Abstract: A package for a semiconductor power device which comprises: a conductive bottom plate as a heat sink; an insulating substrate mounted on the bottom plate; a copper film formed on the insulating substrate to expose a peripheral region of the insulating substrate; semiconductor chips disposed on the copper film; a container arranged on the bottom plate, surrounding the insulating substrate; an external terminal supported through the container and connected electrically with the semiconductor chips; and a silicone gel filled within the container, wherein a solidified insulating material is disposed on an outer edge region of the copper film and the peripheral region of the insulating substrate. Thus, reducing an electric field across the interface and making it difficult to cause a creeping discharge. A notch is formed in the bottom plate, and the notch is filled with a high heat conductive resin. The notch is located outwardly apart from a region where the semiconductor chips are mounted. Thus, a creeping breakdown is prevented without sacrificing a heat radiation effect of the bottom plate. Using a waterproof and flexible film to seal an inlet for filling the silicone gel into the case, a heat stress caused by an expansionand a shrinkage of the silicone gel in response to a variation of temperatures is reduced, and it prevents the silicone gel from being wet. A thermoplastic insulating resin is employed instead of the silicone gel.

Patent CA-2261757-A1 (CA)
Inventor: CHRISTENSON KEITH A
IPC: E05B49/00
Filed: 1997-08-04
Abstract: The present invention teaches a remote control system. The remote control system comprises a transmitter (11) for transmitting a first data signal (12) having a command and an identification code. Further, the remote control system comprises a receiver (13) for receiving the first data signal having an operational mode for initiating the received command if the first received identification code matches a stored authentic and valid identification code, and a programming mode for storing received valid identification codes. The receiver comprises a switch for switching between modes, a memory (33) for storing authentic and valid identification codes, and a processor (26). If the receiver is in the operational mode, the processor accesses the authentic and valid identification codes from memory, compares the first received identification code with the accessed authentic and valid identification codes, and initiates the received command if the received identification code matches with one of the accesses authentic and valid identification codes. If the receiver is in a first session of the programming mode, the processor tests the validity of the first received identification codes, unauthenticates the stored authentic and valid identification codes should the first received identification code be valid, and writes the first received, tested and validated identification code into a first location in memory as authentic and valid.

Filed: 1999-06-04
Abstract: In the hinge device of the present invention, the right-hand spiral cams formed on the lower portion of the rotational shaft 40 are engaged with the right-hand spiral guide grooves 16, and the left-hand inclinated guide protrusions 13 are engaged with the left-hand spiral guide grooves 15 formed on the outer circumference of the elevating pipe 17.      In accordance with such a construction, when the elevating pipe 17 moves upwardly or downwardly, the load produced by hydraulic pressure can be applied uniformly to the shaft 40. Therefore, it is little possible to break out or cut out the spiral cam 15 formed on the shaft 40, the spiral guide grooves 15 and 16 on the elevating pipe 17, the guide protrusion 13 on the stationary pipe 14. As a result, the hinge device of the present invention has relatively longer life-time than prior art. Also, the hinge device of the present invention can reduce or prevent the damage in respect of person life and property.
