Title: Dry etching device and plasma chemical vapor phase deposition apparatus
Inventor: FUKUSHIMA NOBUHITO
IPC: C23F4/00
Filed: 1997-09-17
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of an apparatus and the uniformity of CVD deposition by rotating an antenna of one turn thereby moving the break of the antenna together with the time. SOLUTION: A substrate 1 is set on an electrode 12 and the inside of a chamber 4 is evacuated. An etching gas or gas for CVD is introduced into this chamber. High-frequency electric power is fed to the antenna 5 from a high-frequency power source 11 to make the introduced gas plasmic. The antenna 5 is rotated by a motor 10. The separate high-frequency power is fed to the electrode 12 from a bias power source 14 and the ions in the plasma are withdrawn into the substrate 1 by their self-biasing effect, by which etching or CVD is started. The plasma formed in the chamber 4 is not spatially fixed in the nonuniformity of the antenna shape as the antenna 5 rotates at all times, by which the uniformity of the ions arriving at the surface of the substrate 1 is assured. As a result, the etching speed and the surface distribution of the deposition speed of the CVD are improved.

Title: Control circuit for optical disk
Inventor: HOSHINA YUICHIRO
IPC: G06F3/08
Filed: 1986-10-25
Abstract: PURPOSE:To reduce a processing time by processing all errors per track after processing every track with an error RAM to be written with a sector error information per sector in the track. CONSTITUTION:When a sector address 4 sent from an optical disk drive unit coincides with a sector address 3 for access, an error data 18 per sector in a track is written to a RAM in accordance with an error RAM address 5 corresponding to the sector address. An upper-order control device detects thereby errors generated after the track-by-track process proceeding the next upon no errors generated. If an error is generated, the error RAM is then read out at once to find its error sector and the error batch processing is intensively carried out. Therefore, the upper-order controller is free from such errors during the sector processing while the optical disk rotates without no use, and the processing time is so reduced.

Title: Cloth end control sewing machine
Inventor: HONDA HIROSHI
IPC: D05B27/16
Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To provide a stable margin to seam or a beautiful stitch line under a simple configuration by moving a sewn product so as to obtain the prescribed margin to seam on the basis of end part information detected from the sewn product, when the feed length of an acquired sewn product becomes equal to the prescribed value. SOLUTION: A control means compares cloth feed length with the specified sewing length at a needle location, and when the cloth feed length at the needle location becomes equal to the specified sewing length, the preset reverse stitching process is implemented and a thread is cut. A series of sewing processes for upper and lower clothes is thereby completed. In this case, timing for the change of a rotational ratio among feed rollers 6AL, 6AR, 6UL and 6UR is maintained so as to keep the feed length at the prescribed value and constant by use of the control means without adding an encoder of high resolution or an arithmetic circuit.  In other words, even if a feed pitch changes, a stable margin to seam or a beautiful stitch line can be provided under the application of a simple configuration, regardless of a change in feed pitch, as the rotational ratio among the feed rollers 6AL, 6AR, 6UL and 6UR is always changed at the same position.

Abstract: PURPOSE:To retain a breaking condition when return operation is not made after torque breaking by providing a tapered surface on the corner part of the spring side inner peripheral part of a pressure plate, arranging balls so as to contact the outer periphery cylindrical surface of a hub, the tapered surface, and a ring end surface, and providing an annular groove on the outer periphery cylindrical surface of the hub. CONSTITUTION:A pressure plate 40 is loosely engaged with a hub 20, and plural disc springs 15, an annular ring 16, and plural balls 17 are interposed in a space with an adjusting nut 14 to be threadedly engaged. A V-shaped annular groove 26 is formed on the outer periphery cylindrical surface 25 of the hub 20. Consequently, since the pressure plate 40 is pressed in a right direction via a torque transmission element when an overload occurs in a driven side, the balls 17 drop in the annular groove 26. By the above constitution, since the balls 17 receive force in the outer side in a radius direction from the groove surface 28 of the annular groove 26 due to the pressing force of a spring to be automatically extricated when the pressure plate 40 moves in the left direction, the balls 17 again contact the tapered surface 45 of the pressure plate 40 to become a torque transmission condition.
