Title: Manufacture of magnetic recording medium
Inventor: KUMAI TOSHIO
IPC: G11B5/72
Filed: 1979-07-31
Abstract: PURPOSE: To prevent the abrasion, damage and others of the magnetic coated film and also increase the durability, by forming the minute unevenness in a uniform and easy way with the etching liquid on the surface of the magnetic coated film of the magnetic disc for the purpose of holding the lubricant.  
     CONSTITUTION: For the disc of the contact start-stop (CSS) system, the surface of the magnetic coated film is soaked about 1W10 minutes into the etching liquid of 5W10% nitric acid solution, 1W5% hydrochloric acid, 5W20% acetic acid solution and others to give the etching mainly to the inorganic materials (γ-Fe 2 O 3 , Al 2 O 3 , ZnO, etc.) of the surface layer of the magnetic coated film. Thus the uniform unevenness is formed. Then the carbon fluoride-group lubricating oil or the like is spin-coated on the disc surface in a depth of several hunderds Å. After this, the head treatment of about 200°C is applied to make the lubricant impregnate sufficiently into the hollowed area. In such way, a disc having a small extent of the S/N reduction, the bit error and other faults can be obtained along with the resistance to the CSS frequency of 50,000 or more.

Title: Conveyor automatic snow-plowing device
Inventor: KAMIYOSHI ISAO
IPC: B65G43/00
Filed: 1999-04-05
Abstract: PROBLEM TO BE SOLVED: To provide a noiseless and economical conveyor automatic snow- plowing device. SOLUTION: This device is driven only by a low speed motor by separating a high speed motor 6 from a conveyor and connecting it to a low speed motor 9 by mechanical clutches 4, 7 at the time of plowing snow. Snow lain on a bet 1 is scraped down by a scraper 12. The low speed motor does not disturb inhabitants in the neighbourhood as its generating noise is small. The low speed motor 9 reduces an electric power rate as its power consumption is small. The low speed motor 9 stops in the case when it stops snowing as a flow rate of water flowing as a part of the snow scraped down by the scraper 12 is melted by a heater 14 is measured by a flow meter 15 and the low speed motor 9 is driven in accordance with snow coverage quantity in the case of controlling the number of revolution of the low speed motor 9 according to a signal from the flow meter 15 by a controller 10.  Consequently, wasteful electric power consumption is restrained.

IPC: G11B17/22
Filed: 1993-04-23
Abstract: PURPOSE: To stop a drive unit at the slot position of a selected magazine by monitoring the vertical position of the drive unit through a slit rotated together with a screw shaft while using a photosensor. CONSTITUTION: When a disk change button 30 is operated, information showing the number of slots to move up or down from an elevator position at current time point is applied to a control circuit 31 and according to that information, the control circuit determines a counter number N of the photosensor, defines a reference counter value as N and operates a counter reset circuit 33. While impressing an inverse voltage from the control circuit 31 after the lapse of prescribed time tr , an inverse voltage impress signal INV is sent to an elevator motor driver 34. An elevator motor 13 starts rotating backward, the slit arrives at the optical path of a photocoupler again and rectangular waves are outputted for time tS. Thus, the drive unit is stopped at the slot position of the selected magazine.

Abstract: PURPOSE:To obtain a cheap swingingly grinding device by arranging electrostriction elements linearly or crossly between a swinging spindle, where a grinding tool is mounted, and a fixing frame, and swinging the spindle according to the change of mechanical sizes of those elements. CONSTITUTION:A swinging spindle 14, which is connected by a universal joint 11 to a driven shaft 10 on the rotating side mounted on a retaining cylinder 26 through a bearing 22, is mounted in a swinging cylinder 25 by means of a pair of bearings 24, while a pair of electrostriction elements 23a, 23b are linearly arranged between the swinging cylinder 25 and a fixing frame 21. When a voltage, whereby those elements 23a, 23b extract or contract differentially to each other with respect to the standard size of a grinding tool 15, which is mounted on the downwardly suspended end of a spindle 14, is applied to the elements 23a,23b, a swinging movement in proportion to the magnitude of the voltage and repeating cycle is given to the spindle 14 through the swinging cylinder 25, and the grinding tool 15 thereby grinds the surface of a work 16. A cross-shaped constitution may be used for such electrostriction elements, or only one element may be used with a spring being arranged on the opposing side. Thus, such simple structure facilitates the compactness together with cheapness of a swingingly grinding device.

Title: Solid-state image pickup device
Inventor: MATSUMOTO KAZUYA
IPC: H04N5/372
Filed: 1990-04-17
Abstract: PURPOSE:To make exposure time constant to all picture elements by applying a dot sequential readout resetting system and setting the gate line corresponding to shutter accumulating time to readout gate potential prior to readout operations. CONSTITUTION:This solid-state image pickup device is constituted in such a way that the gate impressing signal phiGm of the line to which resetting operations are performed for shuttering operations prior to readout is set to accumulating gate potential Vgs during picture element CMD readout time (t1, t2,...) and to readout potential Vgr during the resetting time (t1', t2',...) at every picture element following the readout operations. Accordingly, signals are obtained for one picture element only during a picture element CMD readout period and only a desired picture element corresponding to the shutter speed connected to the row line of the same row is reset during the resetting period of the picture element. Therefore, the exposure quantity is made constant to all picture elements and the difference in accumulating time can be eliminated.

Title: Magnetic brush developing device
Inventor: NOGUCHI KOUJI
IPC: G03G15/09
Filed: 1978-08-15
Abstract: PURPOSE: To make conduction constant and eliminate the occurrence of uneven development by making the axial length of the permanent magnet to be mounted in an insulation sleeve shorter than the axial length or a circular cylindrical drum and longer than the axial length of photosensitive material.  
     CONSTITUTION: Photosensitive material 2 is coated to a conductive circular cylindrical drum 1 by the width of l 1 . A plastic-made sleeve 4 is built in with a permanent magnet 5 to convey magnetic toner 7 to the drum 1 and rub the electrostatic latent images formed on the photosensitive material 2. The axial length l 2  of the circular cylindrical permanent magnet 5, the axial length l 3  of the sleeve 4 and the axial length of the photosensitive material 2 are made l 1 <l 2 ≤l 3 . Since the sleeve 4 is non-conductive, the production of flaws by the magnetic toner is obviated and corrosion by air and moisture does not occur. In addition, conduction is accomplished directly to the drum substrate, not by the formation of a conductive path by shaft and frame and therefore there are no troubles and since the conduction constant is maintained constant, there is not occurrence of uneven development or the like.
