Title: Production of optical disk molding substrate excellent in transfer properties
Inventor: MASUDA SEIJI
IPC: G11B7/26
Filed: 1993-11-22
Abstract: PURPOSE:To obtain an optical disk molding substrate excellent in transfer properties and reduced in warpage by subjecting an acrylic resin to injection and compression molding under molding conditions of specific molding temp., mold temp. and mold clamping pressure. CONSTITUTION:A transparent acrylic resin is subjected to injection and compression molding under molding conditions such that molding temp. is 270-290 deg.C, mold temp. is 80-90 deg.C and molding clamping pressure is 10-20 ton to mold an optical disk molding substrate. The thickness of this molding substrate is pref. 1.0mm or less and coma aberration can be reduced. When mold clamping pressure exceeds 20 ton, the warpage of the disk substrate becomes large and, therefore, by performing molding under the above mentioned conditions, the warpage of the optical disk substrate is reduced to 200mum or less and excellent transfer properties wherein the pits on the surface of the molding substrate are 1mum or less are obtained.

Title: Key locking device for video equipment
Inventor: NISHIMURA KOICHI
IPC: G11B15/02
Filed: 1988-11-21
Abstract: PURPOSE:To safely and surely lock and unlock various kinds of modes in view of security by releasing a mode setting lock at the time of reproducing a magnetic tape recorded with a signal for releasing the mode setting lock and setting various kinds of operation modes of the video equipment. CONSTITUTION:A tape cassette 1 housed with the magnetic tape recorded with a particular signal is loaded into a loading part 3 of a VRT 2 constituting the video equipment, and when this magnetic tape is reproduced, the mode setting lock state is released, and by releasing the device from this mode setting lock state, the various kinds of operation modes of the video equipment are now feasible. After setting a mode by an operation key 8, the tape cassette 1 is unloaded from the VTR 2 and kept in a safety place in view of security. In this case, the mode setting lock is under the working state, so that a key- input can never be performed by the operation key 8 unless the tape cassette 1 is loaded again into the VTR 2 to reproduce the magnetic tape of the cassette 1. By this method, safety is ensured very much for the security.

Title: Signal distributing system
Inventor: TSUSHIMA HIDEAKI
IPC: H04B10/00
Filed: 1985-12-27
Abstract: PURPOSE:To obtain a device which is low-cost and small-sized and is superior in workability even if a signal has a wide band, by distributing a signal converted to light with respect to signal distribution in the device. CONSTITUTION:A signal 2 is converted to an optical signal by an electrophoto conversion part 6, and the optical signal is propagated in an optical fiber 7 and is made incident on an optical star coupler 8 and is distributed to n-number of optical signals. Distributed optical signals are propagated in optical fibers 9-1-9-n and are inputted to photoelectric conversion parts 10-1-10-n and are outputted as signals 4-1-4-n whose number is a desired distribution number. Since the optical star coupler fulfills the signal distributing function independent ly of the band width of the signal inputted to the device, a low-cost signal distributing part is attained even if the signal to be distributed has a wide band. Since an optical fiber cable narrower and lighter than a metallic cable is used for wiring, the space occupied by wiring in the device is reduced.

Abstract: PURPOSE:To improve the reducing effect for the impact acting on a driver by installing a bracket for installing a column supporting steering wheel shaft on a car body, so as to be plastically deformed by the force acting from the direction crossing with the column axis center direction in the collision between a steering wheel and a driver. CONSTITUTION:When a vehicle collides with an obstacle at the front, the first and the second columns of a steering device relatively shift, and a part of the impact energy is absorbed by the shearing, etc., of resin. When a driver collides with a steering wheel, the plastically deformable parts of the third and fourth plate-shaped parts 46c and 46d of a lower bracket 46 are plastically deformed by the action of the moment around the axis core Q of a screw shaft based on the force scting from the axis core P direction of the column, and absorbs the impact based on the force acting from the axis center P direction. When an upper bracket is slipped off from a connecting member, the first bendable part 51a is plastically deformed to the side where the bending degree increase, and the second bendable part 52 is plastically deformed to the side where the bending degree decreases, and the impact is absorbed.

Abstract: PURPOSE:To enable a showcase to cope with commodities or the like of different sizes using even a single fence plate by inserting the fence plate between a shelf board front edge and a fence support in such a way as vertically slidable, and adjusting the height of the fence plate via the rotation and vertical motion of a support disc. CONSTITUTION:A vertical gap 15 of suitable length is formed between the front edge of a shelf board 7 and fence supports 82 and 93 in such a way as enabling a fence plate 11 to slide vertically. The lower side of the fence plate 11 inserted in the gap 15 and supported on the front edge of the shelf board 7, and the fence supports 82 and 93, comes to be in contact with and supported on top of a support disc 23. This disc 23 when turned moves up and down along the thread of a screw shaft 22, and the fence plate 11 can be moved up and down concurrently. According to this construction, the height of the fence plate 11 from the top of the shelf board 7 can be adjusted to suit the slope angle of the shelf board 7 and the sizes of displayed commodities. In addition, a single fence plate can meet an intended purpose. Consequently, a work for storing many fence plates becomes unnecessary, different from the case of a conventional showcase.
