Title: Semiconductor device
Inventor: SOEDA SHOICHI
IPC: H01L21/8234
Filed: 1989-12-26
Abstract: PURPOSE:To maintain electrostatic withstand voltage without deteriorating response characteristics of input first-stage circuit, by forming gate oxide film of MOS FET which forms input protective circuit and input first-stage circuit in such a way that the gate oxide-film is thicker than gate oxide film of other internal MOS FET. CONSTITUTION:Gate oxide film of MOS FETs 5' and 6' forming input protective circuit 9, and MOS FETs 12' and 13' forming input first-stage circuit are thicker than those of MOS FETs 14 and 15 and the like forming other internal circuits 11. By thickening gate oxide film of an MOS FET forming input protective circuit 9 and input first-stage circuit 10, electrostatic withstand voltage of gate oxide film is increased. Therefore, electrostatic withstand voltage property can be maintained without increasing resistances of resistors 1 and 2, and stray capacitances 3 and 4 of the input protection circuit 9, and high speed characteristics of the internal circuit 11 is maintained since gate oxide films of other internal circuits 11 is thin. By this, electrostatic withstand voltage property can be maintained without reducing response characteristics of the input first-stage circuit.

Title: Detection of defective piece in tab tape
Inventor: SUGA MIYUKI
IPC: G01N21/89
Filed: 1997-12-10
Abstract: PROBLEM TO BE SOLVED: To provide a method for detecting a defective piece in a TAB tape, wherein the line process time in TAB-tape production is short, the warping of the tape and the reduction of the tape strength do not exist even for a structure, wherein a plurality of pieces are obtained and a dedicated defective-piece detecting sensor is not required. SOLUTION: When a defective piece 2a is detected by the defect inspection prior to processing of a TAB tape, a paper piece 13 with an adhesive compound or coloring paint is added to a position identification lead 11 to obstruct recognition against the defective piece 2a. At processing the TAB tape, the image of a position identification part is picked up so as to perform detection of the defective piece 2a. When the position identification lead 11 can be recognized, the position recognition of a piece 2 is conducted. When the position identification lead 11 cannot be recognized, it is decided that the piece is a defective piece, and processing is made to the next piece.

Title: Variable speed control device for continuous variable transmission
Inventor: SATO YOSHIJI
IPC: B60W10/10
Filed: 1989-12-28
Abstract: PURPOSE:To eliminate meaningless variation in transmission gear ratio by calculating false rotating speeds of a secondary pulley from TCS (traction control system) driving signals and false car-speed signals, and outputting the signals in preference to secondary pulley rotating speed signals. CONSTITUTION:During normal travel of a vehicle, a continuous variable transmis sion is controlled to an optimum transmission gear ratio in response to variable speed control signals from a control unit 96. At this time, when the brake is applied or the wheels slip, TCS control unit 70 performs traction control to output TCS driving signals, calculates false secondary pulley rotating speeds from false car-speed signals by a calculation unit 111, and outputs the rotating speeds in preference to secondary pulley rotating speed signals from a rotating speed sensor 92 by an output switching unit 112. Normal variable speed control is thus temporarily reserved, a control unit 90 performs variable speed control in response to false car-speeds, meaningless variation in transmission gear ratio is thus eliminated, and durability can be improved.
