Title: Production of high-brightness steel sheet
Inventor: SASAKI TSUYOSHI
IPC: B21B27/00
Filed: 1986-09-01
Abstract: PURPOSE:To reduce the production cost of a high-brightness steel sheet by subjecting a roll surface to a hardness distribution uniformizing treatment then to dulling, etc., and executing cold rolling by using such roll. CONSTITUTION:The surface of a roll base material consisting of a high alloy steel is subjected to the hardness distribution uniformizing treatment by metal plating, etc., and is then subjected to dull finishing by a shot blasting method, electric discharge machining method, etc. The surface is subjected to a surface hardening treatment by a Cr plating treatment, nitriding treatment, etc., at need. The cold rolling of the steel sheet is then executed by using the roll subjected to such treatments. The surface roughness of the roll is averaged by the hardness distribution uniformizing treatment and the undulation of the roll surface is eliminated by the dull finishing. The high brightness of the steel sheet at the time of the cold rolling is, therefore, improved. Since the need for large-sized equipment such as laser beam processing equipment is thereby eliminated, the production cost of the high-brightness steel sheet is reduced.

Title: Method for inspecting flaw of optical information recording medium
Inventor: ICHINOSE KEIKO
IPC: G01N21/95
Filed: 1986-09-01
Abstract: PURPOSE:To rapidly detect the flaw of an optical information recording medium with high accuracy, by irradiating an org. membrane with white light through an optical filter capable of cutting a wavelength equal to ore less than the max. absorption wavelength of the org. membrane and detecting the partial variation of the transmitted light thereof. CONSTITUTION:An optical filter 3 cutting a wavelength equal to or less than the max. absorption wavelength of an org. membrane is used in this flaw inspection method. At this time, since the quantity of detection light itself is reduced in a filter cutting the wavelength in a long wavelength region, detection capacity is lowered and effect of a certain degree is shown in a filter cutting the wavelength in a short wavelength region but detection capacity is gradually lowered. By inspecting the flaw of the org. membrane of an optical information recording medium 4 by the visual observation of transmitted light using an apparatus constituted of a light source 1, a diffusion plate 2, an optical filter 3 and a lens system 5, the flaw can be detected rapidly and easily with high accuracy as compared with conventional visual inspection with white light not passed through the optical filter.

Filed: 1993-07-30
Abstract: PURPOSE:To save the electric power of a display device by detecting the presence and distance of a person in the front surface direction of this display device and automatically turning off a power source according to the presence and distance of this person. CONSTITUTION:Two pieces of detecting elements 2a, 2b mounted on the front surface of the display device 1 transmit and receive sound waves, electromagnetic waves or light (IR rays) and detect the presence of the person within the specified distance from the front surface of the display device 1. For example, the IR rays are transmitted and received in the front surface direction by the element 2a. Decision is made that the person exists in the front surface direction when the reflected light is detected. The element 2b transmits and receives the IR rays in a direction deviated by a prescribed angle from the front surface direction. Decision is made that the person exists in this direction when the reflected light is defected. Judgment is made that the person exists within the prescribed distance from the front surface of the display device (i.e., the user seats in front of the display device 1 and the device 1 is operated or is predicted to be operated) when the reflected light is defected by both of the elements 2a, 2b.

Title: Mode switching system or work station
Inventor: HONGO MITSUAKI
IPC: H04L69/14
Filed: 1986-09-03
Abstract: PURPOSE:To allow a controller to command the changeover of the operating mode of a work station automatically by providing an operation mode table of the work station to the controller. CONSTITUTION:When a command designating the operating mode from a host computer 1 to the controller 8, the controller 8 compares the operating mode commanded at the initial setting with the designated operating mode at a mode table 8. When the operating mode is coincident with all the operating modes of work stations 5-7, the changeover of the operating mode 15 commanded by the command to the work stations 5-7. If there is a dissident operating mode, the controller 8 informs it to a host computer 1 that the setting to the designated mode is disabled. Thus, the operating mode of the work station is revised easily.

Filed: 1982-11-26
Abstract: PURPOSE:To obtain characteristics superior in mechanical strength, impact resistance, dimensional stability, thermal deformation resistance, etc. by forming a photosensitive layer on a substrate formed of a plastic filled with potassium titanate fibers. CONSTITUTION:A photosensitive layer is formed on a substrate formed of a plastic filled with potassium titanate single crystal fibers having a compsn. represented by K2O.nTiO2 (n>1). Since said fibers are as small as 1/50-1/100 the size of glass fibers, the substrate very smooth on the surface is obtained. Further, since moldability is improved, it can be reduced in thickness, contributing to the reduction of size and weight. Moreover, it bends back small even when thinned, and it has good dimensional stability, and can be used as the substrate with advantage.

Abstract: PURPOSE:To enable an integration of circuits with suppressed loss of a constant- current source transistor, by providing a maximum voltage detection means which detects the maximum voltage and a power source voltage control means which controls a power source voltage of a constant-current circuit according to the voltage detected. CONSTITUTION:Due to variation in equivalent resistances 21 a comparison between the highest voltage of an electrode 24 and the voltages at the both ends of a resistor 4 is made by a transistor 2, and by controlling a transistor 1 in order to make the both of the above values to be equal (a forward voltage of a diode 5 and a base emitter voltage of the transistor 2 are disregarded) an impedance of the transistor 1 is controlled, and the voltage of a terminal 7 is set. The voltage between the emitter and collector of a transistor 35 may, therefore, be maintained constantly low, if the voltage of a constant-voltage diode 3 is selected to be sufficiently low.
