Title: Open-close body device
Inventor: ONOBORI HIROYUKI
IPC: E06B9/82
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To open and close an open-close body safely by detecting a high temperature in a fire, etc., at an early stage by a simple constitution, and to avoid bringing to an unstable state of opening and closing extremely even when the state at a high temperature is brought by the fire, etc. SOLUTION: A temperature detector 41 detecting a temperature at the time of a fire is mounted to the inside of the lintel of a shutter case and near to an opening section thereof. The temperature detector 41 is connected in series with the opening-side circuit 11 of a control means 10 through heat-resistant wirings 40. When the temperature detector 41 detects a set fixed temperature by the fire, etc., a relay contact is opened, and the electrically driven lifting of a shutter is limited. Accordingly, the shutter can be opened and closed safely at the time of the fire, and the open-close body device contributes to the prevention of the spread of the fire.

Title: Optical card and its production
Inventor: TAKEOKA YOSHIKATSU
IPC: G11B7/2534
Filed: 1986-04-28
Abstract: PURPOSE:To easily attain a recording state in which high reproduction CNR is obtd. by the irradiation of a low-power light beam by using a film which forms build-up deformed parts when irradiated with a beam for recording as a recording film and specifying the elongation rate of the material of an org. intermediate layer. CONSTITUTION:This optical card is formed by successively laminating a transparent org. substrate 1, the recording film 2, the org. intermediate layer 3, and an org. protective plate 4. The build-up deformed parts 5 are formed to the recording film 2 when the film is irradiated with the beam for recording. The recording state in which the high CNR is obtd. by the irradiation of the low-power light beam is easily attained by using such recording film 3. The decrease of the recording sensitivity of the recording film is suppressed and the adhesive strength to the org. protective plate 4 is assured by using the material having the elongation rate ranging 5-100% for the org. intermediate layer 3.

Title: Manufacture of information recording medium substrate and the information recording medium substrate
Inventor: YOSHINO KUNIHIKO
IPC: C03C21/00
Filed: 1998-04-10
Abstract: PROBLEM TO BE SOLVED: To obtain a flat surface which has no protrusion on the surface caused by the residual of abrasives by conducting a finish grinding for a circular shaped substrate employing an artificial leather suede pad, while water is being supplied. SOLUTION: In the production of an information record medium substrate, a finish grinding of the substrate is conducted by an artificial leather suede pad, while water is being supplied. Thus, an information record medium substrate, in which no protrusion caused by the residual of abrasives exists on the surface and having a smooth surface (or a smooth surface having reduced number of protrusions), is realized and the amount of floating of a head is reduced. The finish grinding of the substrate is effective not only for the information record medium substrate, to which a low temperature type ion-exchange process is conducted, but also for the information record medium substrate, for which the low temperature type ion-exchange process has not been applied. A suitable PH value of the water used for the finish grinding is 4 to 10.  Pure water, ion-exchanged water, and tap water can be used as the water. Buffer solution may be used with the water.

Title: Stereoscopic image display method
Inventor: NAKAMURA MITSUE
IPC: G02B27/22
Filed: 1981-06-27
Abstract: PURPOSE:To observe a natural stereoscopic image in a wide observation range while utilizing the parallax between both eyes by projecting an image for the left eye and that for the right eye alternately on one projection screen, and the observing the left and right images separately through spectacles which vary in light transmissivity on the left and right sides alternately synchronizing with said projection switching. CONSTITUTION:While an image for the left eye is projected on a screen 7 by a projector 2, a switch 4 is placed on the left-eye side for closure and then the left-eye light shielding plate 61 of spectacles 6, e.g. a liquid-crystal plate increases in light transmissivity to observe the image with the left eye 81. During this period, the right-eye light shielding plate 62 has light transmissivity and the image is not seen with the right eye 82. When a film 1 is advanced by one frame and an image for the right eye is projected, the left and right are inverted. This operation is repeated >=10 times per second to observe a stereoscopic image. Even when the projection screen is observed at a different position, the image is separated and seen, so that stereoscopic visible range is wide and a natural stereoscopic image is obtained only by being seen through the spectacles.

Abstract: PURPOSE:To obstruct generation of a welding defect, and to form a satisfactory bead, by setting a non-consumable electrode and a consumable electrode as a preceding electrode and a succeeding electrode, respectively, and combining them at a suitable distance. CONSTITUTION:A currents supplied from a welding electric power supply 7 to non-consumable electrodes 2, 2' being preceding electrodes of a welding torch, and a suceeding consumable electrode 4, arcs are generated between them and a material to be welded 1, and welding is executed. To the electrode 4, a wire 5 is fed by a device 13. When a distance between the electrodes 2, 2' and 4 is large, a local heating effect of the preceding electrode is decreased and an incompletely fused overlap bead is generated, therefore, a distance between the electrodes is set to <= about 7mm. at a point where the center line of each electrode contacts with a base metal 1. In this regard, a welding current is supplied  to each electrode alternately by switching elements 8, 8' and 9, 9' in order to  prevent interference of an arc, and these elements are controlled by a device 12.  Also, in order to stabilize an arc of the non-consumable electrode, a high frequency superposing device 11 and arc stabilizing resistances 10, 10' of the consumable electrode are connected.

Title: Fluorescent lamp lighting device
Inventor: SZUBA STEFAN
IPC: H05B37/02
Filed: 1992-04-20
Abstract: PURPOSE: To prolong the life of a fluorescent lamp by providing light intensity control means of the fluorescent lamp and sensor circuit to respond to the expected stimulation with the means to make control signals when the sensor is stimulated. CONSTITUTION: When the piro-electric movement sensor PS senses movement, the output signal of comparator IC5 is low and the transistor Q<4> is turned off, the fluorescent lamp is lighting in condition called 'perfect lighting'. When movement near the sensor PS is over, the comparator IC5 turns off the transistor Q<4> and high level output signal is turned out and the transistor Q<5> turns off to short the resistor R20 . As a result current between the terminal 113' and 114' origin increases and the voltage between these terminals decreases to the voltage drop of regulating small output voltage reference IC6. This voltage makes the fluorescent lamp possible to work in 'dimmed' condition.
