Title: Fingerprint detecting device
Inventor: OKA SHUICHI
IPC: A61B5/117
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a fingerprint detecting device having a low-cost structure that provides high reliability, while making as small as possible an increase in number of processes for preventing static breakdown. SOLUTION: A dummy electrode 8 obtainable from the same process as a detecting electrode 7 is disposed around the detecting electrode 7. The covering state of an insulating film 9 reflecting a step in a contact hole 61 linking the dummy electrode 8 to a wiring layer 5 is such that the thickness T3 of the insulating film on top of the dummy electrode 8 is smaller than the thickness T30 of the insulating film on top of the detecting electrode 7. Even the application of an electrostatic load equal to or greater than the insulating withstand voltage of the insulating film 9 leads only to the breakdown of the top of the dummy electrode 8 and does not lead to a decrease in detecting capability.

Title: Robot control method
Inventor: YAMAMOTO MUTSUMI
IPC: B25J13/00
Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To provide a robot control method capable of increasing the availability factor of a production line, and maintaining efficient production by operating a robot, depending on the status of the production line. SOLUTION: The number of pallets on a conveyor for use in the next process is judged at a step S2 on the basis of a signal from a sensor for detecting the existence or non-existence of a buffer pallet. Then, the operation speed of a robot is made variable and controlled at a step S3, depending on the pallet number P. This operation speed is a multiplier as an overall speed factor for each detailed set speed in a robot operation program, and applied in such a way as superposed to each set speed in the program. For example, when the operation speed is set at 80%, all speeds in the operation program are implemented at values as resulting from the set speed multiplied by 0.8.

Filed: 1984-07-20
Abstract: PURPOSE:To prevent the side tone to make a circuit into an IC by providing a capacitor which cancels inductance components of the characteristics impedance of a transmission line including a transformer to which a microphone and a speaker are connected. CONSTITUTION:The audio signal inputted from a microphone 11 is inputted to an amplifier 7 and an inverting amplifier 8 and is transmitted to an exchange 12 through a transformer 2.

Title: Power supply failure detection system
Inventor: KATO TSUTOMU
IPC: H02M3/28
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To prevent power supply modules connected in parallel to each other from detecting the failure detection erroneously when a load is light. SOLUTION: A system has a comparator 12 which detects the output current of a power supply module and, if the output current is lower than a specified value, detects a current shortage alarm and a comparator 14 which, if a load current applied to a load 16 is lower than a specified value, makes the current shortage alarm invalid. The output current detection signal T3 is connected to the other power supply modules through a diode 10. Although the current shortage alarm which shows the failure of the power supply module is detected by the comparator 12 when the load current is reduced, as the current shortage alarm is made to be invalid by the comparator 14 before the current shortage alarm is detected, the power supply module does not transmit the current shortage alarm T6.

Abstract: PURPOSE:To reduce the area of a memory by half by providing an operation/ selection means which gives either the output of a bias register or an addition/ subtraction result between an output value from the memory and that from the bias register to a bus in accordance with the zero value of a converted value. CONSTITUTION:The memory 9 has an area storing the partial value of a sigmoid function converted value corresponding to a curve obtained by cutting a rotary symmetry curve showing the sigmoid function converted value into half at a symmetry point as a value accessed by an address, and the bias register 6 sets the sigmoid function converted value when the converted value is zero. The operation/selection means 7 and 8 gives either the output of the bias register 6 or the addition/subtraction result between the output value from the memory 9 and the output value from the bias register 6 to the bus 16 in accordance with the zero value of the converted value. Thus, the same function as the sigmoid function conversion of conventional technique can be realized and a layout area can be reduced to almost a half.
