Title: Analog switching circuit
Inventor: KAZUMI MASAHIRO
IPC: H03K17/00
Filed: 1991-12-26
Abstract: PURPOSE:To reduce the influence of a crosstalk by an analog switch by employing the three analog switches and devising a circuit such that each input signal is selected and outputted through 2-stages of the analog switches. CONSTITUTION:Output terminals C of 1st-3rd analog switches SW1-SW3 are all connected to an input terminal A when the switches are driven to select the input terminal A, a 1st input terminal is applied to the input terminal A of the switch SW3 via the switch SW1 and a terminal B is connected to ground via the switch SW2. When the switches are driven to select the terminal B, the output terminals C of 1st-3rd analog switches SW1-SW3 are all connected to the input terminal B, the terminal A of the switch SW3 is connected to ground via the switch SW1 and a 2nd input signal is applied to the terminal B via the switch SW2. Thus, crosstalk superimposed via a static capacitance between a non-selective input terminal and the output terminal is almost halved.

Title: Sheet cutting device
Inventor: FURUYAMA SHUICHI
IPC: B26D1/24
Filed: 1991-12-27
Abstract: PURPOSE:To provide a cutting device, which eliminates such inconvenience that poor performance of cutting occurs due to wear of a guide rail and a tool rest likely in a conventional cutting device in which a disc cutter blade is put in pressure contact with a straight stationary cutter. CONSTITUTION:A sheet cutting device is composed of a first disc cutter blade 1 having a cutting edge at the periphery and shaft-supported rotatably by a tool rest 4, which is supported by a guide rail to make reciprocations, and a second disc cutter blade 2 having cutting edge at the periphery and shaft- supported rotatably by a coupling member which is secured to the tool rest. The cutting edge of the second disc cutter blade 2 is put in pressure contact with the cutting edge of the first disc cutter blade 1 with the resilience of coupling member 6, and thus a sheet 7 is cut. This does not generate any change in the pressure contact of cutter blades with each other even though the members are worn, and there is no risk of poor workmanship of cutting sheet.

Title: Surface mount device
Inventor: KUWABARA MAKOTO
IPC: H01L23/50
Filed: 1993-12-24
Abstract: PURPOSE:To inspect a soldering part and the mounting direction of a package with an X-ray inspection equipment. CONSTITUTION:A part of leads 13 is formed in a shape different from other leads. The different shape lead 13a is constituted as a mark for judging the mounting direction which is detected with an X-ray inspection equipment. The mounting direction of a surface mount device 11 is detected on the basis of the position of the different shape lead 13a. Thereby the mounting direction can be confirmed while the inspection of the soldering part of the surface mount device 11 is performed with the X-ray inspection equipment, and the inspection of the soldering part and the confirmation of the mounting direction can be performed in the same inspection process. Hence, the inspection manhour can be reduced.

Title: Data transferring circuit
Inventor: KIJINO TAKESHI
IPC: G11C19/00
Filed: 1999-12-07
Abstract: PROBLEM TO BE SOLVED: To provide a data transferring circuit which realizes fast data processing with a minimum delay circuit scale by the distribution method of a clock distribution circuit by allowing the skew of a clock signal in some degree. SOLUTION: This data transferring circuit consists of plural flip/flops and uses a signal, which is obtained by deviating one period of a clock signal by a fixed interval regularly, to the clock signal to be distributed to the respective flip-flop. The signal deviated by the fixed interval is a signal obtained by deviating 1/4 period of the clock signal, e.g. regularly. In a method for distributing the signal to the respective flip-flop, the clock signal to be inputted to the flip-flop on a transmission side is delayed compared with the clock signal to be inputted to the flip-flop on a reception side.
