Title: Thyristor converting device
Inventor: KANOU TAKASHI
IPC: H02M1/092
Filed: 1979-06-06
Abstract: PURPOSE:To prevent an optical thyristor from being broken, by connecting together optical fibers extended from a control unit and optical fibers extended from forward voltage protecting circuit so as to limit a total number of the optical fibers in use to the smallest possible level. CONSTITUTION:An optical firing signal from a control unit 2 is sent to gates of optical thyristors LS1-LS2 through an optical fiber Y-X. While a thyristor converting device is operated, a certain thyristor is in some cases turned off due to an abnormal phenomenon. In order to turn on the thyristor immediately in such a case, a forward overvoltage protecting circuit D corresponding to the thyristor is energized to send an optical firing signal through an optical fiber Z-Y. This structure, as compared with a structure wherein a refiring signal is sent from the control unit 2, permits reducing the number of optical fibers and preventing, owing to quick generation of a refiring signal, the thyristors from being broken. Furthermore, the joint portion X of the optical fibers can be kept airtight easily.

Title: Reel hub
Inventor: OOMORI OSAMU
IPC: G11B15/32
Filed: 1984-04-09
Abstract: PURPOSE:To make fitting of a reel easy without increasing the number of parts to be used, by using a long circular hole as the hole at the rotating center of a key and locking the reel through the parallel movement of the key, and then, utilizing the restoring force of a rubber ring for locking to the returning force of the key. CONSTITUTION:At the time of locking, a cam 24 moves leftward in parallel with a motor shaft 8 and, as a result of this movement, a key 18 moves so that it is expanded in the radial direction. Since the long circular hole 22 of the key 18 and a pin are not fixed when the key 18 moves, the key 18 moves in the radial direction under a condition where the key 18 is set in parallel with the inner diameter face 5 of a reel. Therefore, the entire surface of the key 18 contacts with the inner diameter face 5 and strong frictional force is obtained by means of a rubber ring 23, resulting in sufficient locking. Then the locking condition is released, the key 18 is returned while it is moved in parallel by the restoring force of the rubber ring 23. When such arrangement is made, a sufficient clearance can be set between the key 18 and inner diameter face 5 of the reel and the reel 4 can be fitted easily.

Title: Conveyor for continuous sheet in use on recorder
Inventor: NOJIMA TAKASHI
IPC: B65H20/20
Filed: 1989-03-22
Abstract: PURPOSE:To keep off a break and a jam around a continuous sheet conveying hole by installing a rotor, conveying a continuous sheet by dint of frictional force at speed slower than that of a tractor, and a means conveying it at more than the conveying speed of the rotor, respectively. CONSTITUTION:Force in an A direction by the dead load and friction or the like of paper is imposed on a continuous sheet 3 to be fed. This force A increases force B of rolling the continuous sheet on a feed roller 201, thereby increasing frictional force of the feed roller 201. Therefore, the continuous sheet 3 is fed speedier as much as 10-15% than conveying speed of a pin wheel 1, and thereby it is slackened between a friction roller 5 and the feed roller 201. When the continuous sheet is loosened, the force B of winding it on the feed roller 201 is decreased to some extent, so that the speed-up feed is no longer carried out, thus slackening of the continuous sheet is eliminated. With this operation repeated, the sheet slides on the friction roller 5 without winding round, thus any slack at a recorder is prevented from occurring.
