IPC: C23C2/06
Filed: 1993-03-10
Abstract: PURPOSE:To produce a hot-dip Zn-Al alloy plated hot rolled steel sheet of high quality free from alligatoring unplated parts by subjecting a hot rolled steel sheet to skin pass rolling, thereafter pickling it, furthermore subjecting the surface to reduction with hydrogen and subsequently applying it with hot-dip Zn-Al plating. CONSTITUTION:A black film steel sheet as hot-rolled is subjected to skin pass rolling of <=0.5% elongation percentage to generate cracks on black film scales on the surface, and after that, it is pickled by hydrochloric acid or the like to dissolve away the scales. Next, the surface is subjected to reduction by a hydrogen gas to completely eliminate oxides and is cleaned, and after that, it is immersed in a hot-dip plating bath of a Zn-Al alloy contg. 3.5 to 75% Al, by which the hot-dip Zn-Al alloy plated hot rolled steel sheet of excellent quality free from alligatoring unplated parts can be produced.

Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of any crystal defect during the course of a heat treatment after a buried strap is formed. SOLUTION: After a first conductive area 105 is formed by filling up the trench of a semiconductor substrate with a conductive material doped with an impurity, an insulating layer 106 is formed on the side wall of the trench and a second conductive area 107 is formed in the trench by etching back the area 105. Then, after the layer 106 and area 107 are etch-backed, a nondoped amorphous silicon layer 108 is formed where the insulating layer 106 and conductive area 107 are etched back and, after the silicon layer 108 is etched back, the amorphous silicon of the layer 108 is recrystallized.  Thereafter, an impurity is diffused outward in the semiconductor substrate through the recrystallized silicon layer 108 and a buried strap which connects the first and second conductive areas 105 and 107 in the trench to a source-drain area is constituted of the impurity and the recrystallized silicon layer 108.

Title: Sorter equipped with stapler
Inventor: KAWANO MINORU
IPC: G03G15/00
Filed: 1991-04-10
Abstract: PURPOSE:To staple sheets in a specific position by stabilizing a bin stop position by a method wherein when a bin reaches the stop position a cam follower stops the swing of an arm component by the contact of the cam follower with the equiradial cam surface of a cam plate. CONSTITUTION:A cam plate 75 integrated with a rotary shaft 74 is rotated by drive of a motor M3, and a follower shaft 78 transfers a transfer component 77 to go straight on. Besides, it moves a groove part 75A of the cam plate 75 outside to swing a first arm 71A and after getting out from the groove part 75A, it slides on a curved surface of a circular arc part 75B of equiradii. Prior thereto, a shielding plate part G8A at a tail part of a sector gear G8 shields an optical path of a photointerruptor PS2, and makes a power source off to stop a drive circuit of the motor M3. Therefore, though there is some overrun after stopping rotation of the motor M3, since the follower shaft 78 transfers along the equiradial circular arc part 75B of the cam plate 75 and stops, the first arm 71A and a second arm 71B keep stop positions at a specific angle, and a bin 41 stops in a specific position.

Filed: 1981-05-25
Abstract: PURPOSE: To remove the materials stuck on membrane surfaces by the physical cleaning effect of foam and to sterilize the membrane by ozone simultaneously by supplying ozone-contg. water as cleaning water to a membrane module.  
     CONSTITUTION: To clean a membrane module 12, a velve 8 is closed and a valve 9 is opened to supply industrial water from a water storage tank 10 into the module 12 by means of a high pressure pump 11.

The ozone- contg. water is supplied to the module 12. The position for the ozone injection is preferably near the membrane module. According to this method, ozone self- decomposes quickly in the water and makes the water pollution-free, thus eliminating the need for post-treatment of the waste liquid of the cleaning.

Abstract: PURPOSE:To prevent vibration of a mechanism part and to attain the small sized device even when the device main body is subjected to direct shock and vibration by providing a support member supporting the mechanism section to the device main body with vibration prevention. CONSTITUTION:An optical disk 1 is provided with a mechanism chamber and a signal processing chamber 9 sectioned by a flat plate base 5 in a box shaped device main body 3 and the base 5 is supported to a bottom 11 of the device main body 3 by means of, e.g., a bowl shaped vibration preventing rubber 13 (support member). Thus, even when the device main body 3 is subjected to direct shock, no vibration is exerted to the mechanism section on the base 5 so as to prevent deflection of rotation of an optical disk 29 and deflection of the movement of an optical head 47 thereby preventing the deterioration in the recording/reproducing performance. Since the mechanism section is supported in vibration-proof in the inside of the device main body 3, it is not required to design a large device mount face of a rack taking the vibration amplitude of the device main body into account and the entire system around the optical disk device 1 is miniaturized.

IPC: H02P6/08
Filed: 1988-04-01
Abstract: PURPOSE:To generate great torque at the time of starting and improve rise characteristics, by driving with the electrical conduction of 120 degrees at the time of starting, and by switching it to the electrical conduction of 180 degrees to perform steady-state operation when a device comes to have a previously set rotational frequency. CONSTITUTION:A three-phase DC motor is composed of the stator of 12 poles and the rotor of 8 poles, and the stator is wound up with a winding 4 to form a Y- connection. The rotor consists of permanent magnets, and three Hall elements Hu-Hw which are rotatable at intervals at the electrical angle of 120 degrees are arranged. The driving circuit of the motor consists of comparators C1-C3, exclusive OR gates X1-X3, try state buffers B1-B9, and the like, and each output from the Hall elements Hu-Hw is compared with each other by the comparators C1-C3, and specified signal processing is performed and after that, the output of driving current to the winding 4 is generated. In this case, a device is driven with the conduction of 120 degrees which can obtain great torque at the time of starting, and when the device comes to previously set rotational frequency, then the conduction is switched to the conduction of 180 degrees. As a result, even if great current is not permitted to flow at the time of starting, rise can be quickly performed with the great torque.
