Title: Cooling water recirculating apparatus for electric machinery
Inventor: ISHII HIDEMASA
IPC: C02F1/52
Filed: 1983-07-11
Abstract: PURPOSE:To prevent the occulusion of a water path, by providing a filter wherein a heat exchanger is connected to a closed pipeline for recirculating pure water for cooling electric machinery by a pump and a pH controller 8 for injecting alkali is connected to the aforementioned pipeline in the upstream side of said heat exchanger. CONSTITUTION:An alkaline chemical solution is injected in the pipeline 2d from a pH controller 8 to adjust the pH of pure water to 8 and colloidal impurities in pure water are flocculated to precipitate particles of impurities with a large particle size. Therefore, the particles of impurities are collected and removed by a filter 5 and there is no possibility for imparting adverse influence on electric machinery 1. On the other hand, when alkaline pure water is supplied to the electric machinery as it is, there is possibility for damaging the electric machinery 1 because of the alkalinity thereof but there is no anxiety because the pH value of pure water is returned in the vicinity of 7 by passing pure water through an ion exchange resin tower 6.

Title: Fingerprint image pickup device
Inventor: KODA SHIGETO
IPC: H04N5/225
Filed: 1994-06-08
Abstract: PURPOSE:To provide a fingerprint image pickup device which picks up images of the ridgeline and through line parts of a fingerprint with high S/N to improve the collation accuracy in a fingerprint collation system. CONSTITUTION:A fingerprint is defined as a test specimen, and a finger 20 touches a surface 23 set opposite to an object 22 that is set opposite to the test specimen. Then the surface 23 is illuminated by a light source 21 from the inner side of the object 22 through a polarizing filter 30, and the reflected image of the test specimen touching the surface 23 is picked up by an image pickup device 27. The illuminating light is made incident on the surface 23 at an angle for total internal reflection and made to be linearly polarized (P polarization) with the vibration plane parallel to the incidence plane. Therefore if the quantity of light reflected from the through line part of the fingerprint is set to be approximately and the one from the ridgeline part, p1 (P), then the S/N ratio is 1/p1 (P). The S/N ratio is improved since the conventional S/N ratio in the case of non-polarized illumination which includes both P polarization and S polarization (the quantity of reflected light p1 (S)) is 2/p1(P)+p1 (S)) and p1 (P)<p1 (S).

Title: Nonvolatile semiconductor disk device
Inventor: BEPPU ATSUSHI
IPC: G06K19/07
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To limit a current at the time of the write operation of a disk card and to reduce the power supply capacity of a processor. SOLUTION: When write data are supplied from the processor 1 through an interface part 10, the write data are tentatively stored in the buffer memory 31 of a disk control part 30A. A piece number management part 32 manages the number of memory chips 50i [where (i)=(a)-(n)] performing the write operation, and when the number of the memory chips 50i during the write operation does not reach a fixed number, the write data are transferred to the memory chip 50i allocated to a corresponding write area. When the number of the memory chips 50i during the write operation reaches the fixed number, after the write operation of the memory chips 50i during the write operation is ended, the write data are transferred. Thus, the entire current at the time of the write operation of the disk card is limited.

Title: Monitor device for control system
Inventor: HAYAMA YASUNOBU
IPC: G01M99/00
Filed: 1983-07-12
Abstract: PURPOSE:To detect a fault or a defect with high sensitivity by monitoring at all times the regression coefficients corresponding to the control neutral point and the control system gain respectively and monitoring these coefficients. CONSTITUTION:A regression coefficient (a) corresponding to the control neutral point calculated by a regression coefficient operator 23 is supplied to a neutral point fault detector 25. If the coefficient (a) gets out of a prescribed neutral point range of -L1-L1, an occurrence of a fault is displayed to a neutral point display device 27. While a regression line (b) corresponding to the control system gain calculated by the operator 23 is supplied to a gain fault detector 26. If this line (b) gets out of a prescribed gain range L2-L3, the detector 26 functions to display a fault. In this case, both coefficient (a) and line (b) are always recorded to a recorder 29. Thus even a small fault is never overlooked despite the monitor for a control system having high response performance. As a result, a fault or a defect can be detected with high sensitivity.
