Title: Optical information recording and reproducing device
Inventor: MORITSUGU MASAHARU
IPC: G11B11/105
Filed: 1986-08-12
Abstract: PURPOSE:To increase the wavelength margin of an optical filter and to facilitate the manufacture by using the light of one side light source for recording and erasing and the light of other light source for reproducing, in a light magnetic disk device to use two light sources of a different wavelength. CONSTITUTION:The light beam emitted from semiconductor lasers 1 and 5 comes to be a parallel light flux, is made incident on round correcting prisms 3 and 7, is made incident on beam splitters 4 and 8 and respectively emitted as light beams 22 and 21. A light beam 21, in which a light beam 22 is polarized by a reflecting mirror 10, is made incident on an optical filter 11 and irradiates the surface of media 14. The reflected light beam arrives at an optical filter 11, is separated, one side reproducing light is made incident on a polarizing beam splitter 17, separated, is made incident on a four-divided light detecting device 20 and outputted as the reproducing signal and the focus error.

Title: Valve operating device for internal-combustion engine
Inventor: HATSUTORI HAJIME
IPC: F02D13/02
Filed: 1982-10-29
Abstract: PURPOSE:To prevent the mixing of air into the oil to thereby improve the response property of the valve operating device by a method wherein in an apparatus for stopping the operation of an air intake or an air exhaust valve by moving the fulcrum point of a rocker arm by an oil pressure, an oil flow passage is closed at the time when the operation of the valve is stopped. CONSTITUTION:The rocker arm 4 is supported by a fixing member 22 so as to oscillate freely so that the movement of a cam 28 is transmitted to the air intake or the air exhaust valve 16. The fixing member 22 is shifted from its operating position to its stop position by a cylinder mechanism 24 and the fixing member 22 is shifted to the stop position, while a fluid pressure return flow passage 52 is operated and then closed when flow passage opening and closing valves 48a and 48b are switched due to a signal from a position detector 70. Thus, by the closing of the flow passage 52, the mixing of air into the fluid (oil) is prevented to thereby improve the response property of the cylinder mechanism 24.

Title: Speed controller for induction motor
Inventor: KUSUMOTO SATOSHI
IPC: H02P25/26
Filed: 1982-10-29
Abstract: PURPOSE:To prevent a chopper element from being damaged due to an overcurrent by providing instantaneous current detecting means and overcurrent level setting means and forcibly turning OFF the chopper element. CONSTITUTION:A voltage comparator 21 compares the instantaneous value (f) of the secondary current detected by a DC current transformer 8 with the overcurrent level (e) set by a setter 20. When both coincides, a monostable multivibrator 22 is driven at every time to generate a pulse output (g) having a continuous period (t). Since this output (g) closes an AND gate 23 only during a low level period, the output pulse waveform (c) of a voltage detector 13 is intermittently interrupted and applied to a chopper 7, and the chopper 7 is turned to OFF. In this manner, since the instantaneous value of the secondary current idc does not exceed the overcurrent level, there exists no possibility that the chopper 7 is damaged.

Title: Io processor for controlling peripheral device
Inventor: TAKAHASHI YASUMI
IPC: G06F13/00
Filed: 1986-08-13
Abstract: PURPOSE:To improve the working efficiency of an system by securing a microprocessor which divided a diagnosis interruption instruction discontinues its executing processing and controlling the working of each part in response to a diagnosis programs stored previously in a memory means. CONSTITUTION:A diagnosis resetting action, a forcible stopping action and a self-diagnosis are carried out separately by a diagnosis interruption instruction received from a main control processor 1. Then a microprocessor 3a is stopped after the end of each diagnosis. In case the software detects such a fault that is unrecoverable during the self-diagnosis or during execution of a normal function execution program, the information on the fault analysis is set to a prescribed storing means and a microprocessor 3a is stopped. Then the data on fault analysis are transferred to the processor 1. Thus it is possible to obtain accurately and automatically the analysis data on the factor of the fault produced by a peripheral device control IO processor. In such a way, the system working efficiency is improved.

Title: Digital photography printing method
Inventor: KIMURA TSUTOMU
IPC: G03B27/72
Filed: 1996-07-19
Abstract: PROBLEM TO BE SOLVED: To print an image picked up by means of a digital camera onto a photosensitive material with an appropriate color tone. SOLUTION: A digital camera 52 stores an image being picked up in the form of digital information. Since the spectral sensitivity of an image signal outputted from the digital camera 52 is different from the spectral sensitivity distribution of a photosensitive material (photographic paper), the image signal is corrected based on the spectral sensitivity distribution of the photosensitive material. The image data picked up by means of the digital camera 52 is corrected so that the average value G of all pixel data G(i, j) will be equal to the central value of resolution in the spectral sensitivity distribution of the photographic paper. Furthermore, the photographic paper can be printed with an appropriate color tone by converting a corrected data G' (i, j) into a data suitable for a photographic printer 10.
