Title: Heat absorbing/radiating device
Inventor: NISHIZAWA MICHIO
IPC: F24S90/00
Filed: 1988-04-05
Abstract: PURPOSE:To provide excellent heat collection performance by a method wherein an outer cylinder member is formed by a material permeable to solar beams, an inner cylinder member has an inlet and an outlet for a heating medium, a heat accumulating tank for the heating medium is formed at the inside, and selection absorbing film treatment is applied on the half periphery of an outer peripheral surface and radiant film treatment on the remaining half periphery. CONSTITUTION:A heat absorbing/radiating device 10 comprises outer and inner cylinder members 11 and 12, and a space therebetween forms a vacuum chamber 13. The outer cylinder member 11 is formed of a material transmitting sunlight. The inner cylinder member 12 has an inlet 14A and an outlet 14B for a heating medium, and the inside is formed as a heat storing tank 15 for a heating medium. A selectively absorbing film is coated on a half periphery 12A of the outer peripheral surface of the inner cylinder member 12, and a radiation film on a remaining half periphery 12B. When a shutter element 16 on the inner periphery of which reflection mirror surface treatment is applied is located at a position where the shutter element 16 faces the radiation film treatment part 12B, solar energy is effectively absorbed by the selectively absorbing film treatment part 12A, water of the heating medium is heated, and produced hot water is stored in the heat storing tank 15. When the shutter element 16 is located at a position where the shutter element 16 faces the selectively absorbing treatment part 12A, sunlight incidence is prevented.

IPC: H01L21/306
Filed: 1987-04-02
Abstract: PURPOSE:To simplify the analysis of a product by a method wherein oxide films, whose thicknesses are different from each other, are continuously formed on the periphery of a semiconductor chip constituting a semiconductor device extending from the center of the chip to its outer periphery and these films are used as a monitor for the amount of etching. CONSTITUTION:A region 4, through which a semiconductor chip is exposed, is provided on the central part of the chip using the periphery of the chip and an about 0.1 mum thick oxide film 1 is formed encircling this region by an oxidation production method (LOCOS method). Then, a 0.4 mum thick oxide film 2 is formed around this film 1 by a LOCOS method and moreover, a 1.4 mum thick oxide film 3 is formed by a LOCOS method. In such a way, the films 1-3 are used as a monitor for etching and the thicknesses of the films are confirmed by a change in the colors at the time they are etched, that is, a generated milk white, a reflected color and so on. According to such a way, a means for peeling the films for analysis is not needed and to know simply the aim of the amount of etching becomes possible.

Title: Plate-like member feed device
Inventor: OOHARA HIROYUKI
IPC: B65H5/10
Filed: 1983-05-11
Abstract: PURPOSE:To enhance the accuracy of prevention of overlapping feed in a paper feed device for a printing machine or the like, by providing two suction cup trains and as well by retracting the front train of suction cups from its suction position after completion of air-loosening. CONSTITUTION:The uppermost one of stacked plate-like members 1 is sucked up by suction cups 2, 3 in a position A to be lifted to a position B, and is subjected to air-loosening by air blown from a nozzle 4 to separate a paper which is overlapped with the plate-like member 1. After completion of air-loosening the suction cup groups 2, 3 are lowered to a position C, and the suction of the suction cups 2 is ceased to release the front end of the plate-like member for relatively moving the same toward the suction cup train 3. Therefore, the front end of the plate-like member 1 droops, and therefore, is clamped onto a belt- conveyor 5. With this arrangement by using two suction cup trains, the droop of the plate-like member 1 is prevented to surely prevent the overlapping feed.

Title: Optical character reading system
Inventor: MICHINO MASAO
IPC: G06K9/20
Filed: 1986-04-09
Abstract: PURPOSE:To automatically read plural types of the form by executing the down-loading only when the response without a form is executed from a general- use computer. CONSTITUTION:From a general-use computer 8, a reading command including a form designation is sent to an optical character reader 9. The optical character reader 9, when the commanded form does not exist in a form buffer 7, reports to the general-use computer 8 that the form does not exist and downloads successively the form from the general-use computer 8. Thus, when the slip of plural types of the form is read, without being conscious of which form is downloaded, the form can be easily and automatically replaced to a new form by the small quantity of a form buffer capacity.

Filed: 1988-04-04
Abstract: PURPOSE:To incorporate a transmission line into one system by converting a signal being the result of superimposing a control signal onto a hi-fi modulation signal into an optical signal, transmitting the signal as light, converting the received optical signal into an electric signal, separating the hi-fi modulation signal and the control signal and using the control signal so as to control the synchronizing operation between the transmission side and the reception side. CONSTITUTION:A signal superimposing circuit 5 superimposes the synchronizing operation control system from a synchronizing operation control signal generator 3 onto the hi-fi modulation signal from a hi-fi modulating circuit 4. An LED drive circuit 6 drives an LED 7 according to an output of the signal superimposing circuit 5 and converts the electric signal into an optical signal. A photodiode 10 converts the optical signal into the electric signal. A low pass filter 12 extracts a synchronizing operation control signal from a signal being the result of the output signal of the photodiode 10 being amplified by an amplification circuit 11 and a high pass filter 16 extracts a hi-fi modulation signal. A system microcomputer 14 controls a DAT mechanism 15 based on the synchronizing operation control signal from a limiter amplifier 13. Thus, the transmission line is unified into one system.

Title: Objective lens driving device
Inventor: ISHIZUKA ATSUSHI
IPC: G11B7/09
Filed: 1995-03-16
Abstract: PURPOSE: To provide an objective lens driving device capable of stably suppressing the resonance of metallic wires for supporting a lens holder with a smaller amt. of viscoelastic material. CONSTITUTION: This objective lens driving device has the lens holder for holding an objective lens, a supporting substrate 18 for supporting the lens holder with the metallic wires 15a to 15d, the viscoelastic material 24 for suppressing the resonance of the metallic wires by enclosing these metallic wires and a sus-holder 16 for holding these viscoelastic material 24. The sus-holder is provided with holes of the sectional areas substantially decreasing from the side of the lens holder toward the side of the supporting substrate. The metallic wires 15a to 15d are discretely inserted into these holes and the holes are packed with the viscoelastic maternal 24. The volume to be packed with the viscoelastic material is decreased, the amt. of the viscoelastic material to be used is decreased and the variation and unequal temp. at the time of curing are eliminated.  The displacement by the resonance of the metallic wires is small on the side of the supporting substrate and increases toward the lens holder but the amt. of the viscoelastic material enclosing the metallic wires increases as well in compliance with the displacement and, therefore, the resonance of the metallic wires is adequately suppressed regardless of the decreased amt. of the viscoelastic material.
