Title: Frequency division circuit
Inventor: TAKAHASHI YUTAKA
IPC: G01R31/30
Filed: 1987-05-28
Abstract: PURPOSE:To perform a test in a time equivalent to the test time of one of frequency divider even for the test of the frequency division circuit in which plural frequency dividers are connected in series, by inputting a testing clock from the common signal input terminal of each input selection circuit in parallel at the time of testing, and deciding the coincidence of the output signals of the frequency dividers. CONSTITUTION:At the time of testing, firstly, the output of an FF8 is set at a high level, and after that, a set signal Vs is maintained at the high level. Next, the inputs of the input selection circuits 1-3 are switched to the common signal line L side of a testing clock signal VIN2 by a control signal VC, and the testing clock signal VIN2 whose cycle is smaller that of a clock signal VIN1 is inputted in parallel with the frequency dividers 4-6. When all frequency dividers 4-6 are operated normally, the output of each of the frequency dividers 4-6 goes to the same level, and an exclusive NOR circuit 7 outputs a high level signal that is a coincidence signal. Therefore, since the number of clocks required for the confirmation of an operation is remarkably reduced compared with a conventional circuit, it is possible to drastically shorten the test time.

Title: Method and device for detecting scum rising
Inventor: ENDO HIROHISA
IPC: B21D28/24
Filed: 1994-05-25
Abstract: PURPOSE:To surely detect even small scums by outputting a control signal from a compared result between a displacement gradient and a reference value. CONSTITUTION:The displacement of a stripper 7 is detected by a displacement sensor 11. A target 12 is fixed to a stripper backing plate 6. A plate material 9 is clamped between the stripper 7 and a die 8, and punching is performed between a punch 1 and the die 8. Scums fall from a scum hole 10. However, scums occasionally deposit to the tip of the punch 1 and a product is scratched with a foreign matter by being caught between the top and bottom of the plate material 9. Therefore, a displacement before and after the stripper 7 is collided with the material 9 to be worked is detected by a sensor 11, and a displacement gradient immediately before the bottom dead point is calculated from the displacement of the stripper 7. The displacement gradient is compared with a prescribed reference position, and a control signal is outputted based on the compared result. Thus, the detecting accuracy for scum rising may be enhanced.

Title: Production for pattern mask
Inventor: MORIMOTO HIROAKI
IPC: G03F1/68
Filed: 1981-08-27
Abstract: PURPOSE:To obtain a pattern mask having less pattern defects due to pinholes, by forming the first resist pattern and the second resist pattern having the same form as the first resist pattern in piles on a mask film. CONSTITUTION:The first resist pattern 3a for forming a semiconductor chip is formed on the surface of a mask film 2 which is formed on the main face of a mask substrate 1. A photoresist film 13 is formed on the first resist pattern 3a, and a pattern having the same form as the first resist pattern 3a is described and exposed and developed to form the second resist pattern 13a. Next, a pattern mask is produced in the step where parts of the mask film 2 where resist patterns 3a and 13a are not formed are etched selectively. Thus, since there is little probability that a pinhole is generated in the same position of first and second resist patterns 3a and 13a, the pattern mask where pattern defects due to  pinholes are lessened considerably is obtained.

Title: Semiconductor photodetector device
Inventor: MATSUZAKI HITOSHI
IPC: G02B6/42
Filed: 1982-08-06
Abstract: PURPOSE:To provide a fiber-containing semiconductor photodetector device which has good yield without producing malfunction at solder curing time by forming the diameter of a clad of photodetecting fiber approximately equal to that of a photodetecting part of a photodetector diode. CONSTITUTION:The diameter phiD1 of a clad 31 and the diameter phiD3 of a photodetector diode 33 are formed to be approximately equal. Thus, the diameter of a spot on a photodetecting part of incident light from a light source for centering becomes approximately equal to the diameter of the photodetecting part, and when an optical fiber 34 is disposed at the center of the diode 33, the output current becomes the maximum value. As it displaces from the center, the spot of the incident light is displaced externally of the diameter of the photodetecting part thereby causing the output current to be decreased. In this manner, in the centering work, it is set so that the output current becomes the maximum value. Then, the optical fiber is always moved to the center of the photodetecting diameter. Since the light passes only through a core in the used state, the output current does not decrease even if the displacement of approx. 100mum occurs in the step of soldering for the light passing through the core.
