Title: Bearing unit of high speed rotary machine
Inventor: YUSHINA MASAYUKI
IPC: H02K11/00
Filed: 1985-02-15
Abstract: PURPOSE:To enable to start at a high speed by forming an annular groove in a housing to surround the outer race of a bearing, burying a heater in the groove, and heating the periphery of the race at starting time, thereby avoiding the increase in the frictional loss of rollers. CONSTITUTION:When a through hole 3a is formed in a housing 3 to engage and support the outer race 4 of a roller bearing 3 engaged with a rotational shaft 1, an annular groove 3b is formed on the inner periphery of the hole 3a. A heater 9 is contained in the groove 3b to heat the vicinity of the race 4 prior to the start of a rotary machine. Thus, since the inner diameter of the race 4 increases, even if quickly started, a friction between the race 4 and the rollers 6 decreases to prevent the bearing 2 from burning.

Title: Disk cartridge
Inventor: YOSHIKAWA KIKUO
IPC: G11B23/03
Filed: 1989-02-07
Abstract: PURPOSE:To regulate the rotation of a disk on a tray at the time of mounting the disk by providing a ragged part on an outer peripheral part of the disk and a lower part of a circumferential wall of a recessed part of the tray respectively and holding unrotatively the disk with the ragged parts engaged with each other at the time of nonfloating. CONSTITUTION:The ragged parts 1d and 9 are provided on the outer peripheral part of the disk 1 and the lower part of the circumferential wall of the recessed part of the tray 2. Then, at the time of nonfloating of the disk 1 from the tray 2, the ragged parts 1d and 9 are engaged with each other to hold unrotatively the disk 1. By this method, the rotation of the disk 1 against the tray 2 at the time of nonuse is regulated by the ragged parts 1d and 9, thus preventing the disk 1 from flawing due to rotation/sliding during the time of carrying or transportation, etc. Then, at the time of use, the disk is easily released from this regulation, and the mechanism can be simplified with reduction of cost.

Title: T-joint weld groove
Inventor: FUKAYA YASUHIRO
IPC: B23K33/00
Filed: 1986-02-13
Abstract: PURPOSE:To uniformize a melt-through bead by varying a groove width in accordance with a plate thickness of a rib-shaped member, and also, forming an intermittent gap part between a groove edge part of a wave shape and a rib-shaped member. CONSTITUTION:Width of a groove 4 is varied successively in accordance with a variation of a plate thickness of a rib-shaped member 2, and also, a groove edge part is formed to a wave shape, and between the rib-shaped member 2 and the groove edge part, an intermittent gap part and a polymerized part are formed. When welding is executed, an upper plate 3 and the rib 2 are welded in a T-shape by a weld metal 5, and a melt-through bead 6 is formed in the reverse side of the weld metal. In this case, since the groove which has formed the intermittent gap part has been used, heat comes not to be transferred easily to an intermediate part from a thin wall part of the rib 2 whose heat transfer quantity is small, it can be prevented that the thin wall side of the rib 2 is filled with heat. Accordingly, no burn-through of the weld metal 5 exists, and the melt-through bead can be formed uniformly.

Title: Electrochemical detector
Inventor: HAGIWARA BUNJI
IPC: G01N27/28
Filed: 1982-02-22
Abstract: PURPOSE:To enable manufacture of an electrode device which has a high-sensitivity and a small capacity, by a method wherein a porous flat plate and a measuring electrode are positioned facing and opposite to each other, and a contrast electrode and an auxiliary electrode are located to the back of the flat plate. CONSTITUTION:A measuring electrode 1 has a flat responsing surface which is located so that it forms one wall surface of a flow path of liquid to be measured. A porous flat plate 3 is positioned in parallel and close and facing and opposite to the responsing surface of the electrode 1 at a distance being sufficiently shorter than a width in all the directions of the responsing surface of the electrode 1. The flat plate 3 forms the other wall surface of the flow path, and has denseness, a water-containing property, and a property which prevents liquid to be measured from flowing therethrough but allows ion to permeate therethrough. An electrolyte gathering part 4 and a reference electrode 2 are placed to the pack of the flat plate 3. The liquid to be measured flows between the electrode 1 and a porous liquid path 3, and an electrolytic current produced by an oxidizing reduction method flows in the direction of the reference electrode 2 from the electrode 1 through the liquid path 3, and thereby the current is amplified to record it.

When the drive part 8 is operated, the rod 7 falls and the piston 4 also falls. Whereupon, the pressure in the cylinder 3 is raised and a viscous material is discharged from the emitting orifice 2. When the drive part 8 is reversely operated after the viscous material 1 is discharged, the pressure to the piston 4 of the rod 7 is released and the pressure in the cylinder 3 is allowed to fall.

Title: Multilayer interconnection method
Inventor: EHATA TOSHIKI
IPC: H01L23/522
Filed: 1983-02-21
Abstract: PURPOSE:To improve the yield of an air bridge by covering lower layer wirings with an insulating material which is softened at high temperature of 500 deg.C or lower, forming upper layer wirings, and removing by gas plasma the insulating material, thereby eliminating the restriction in the steps due to the stepwise disconnection and weakness in mechanical strength. CONSTITUTION:Upper layer wirings 22 cross lower layer wirings 21 through an insulating film 23 having a smooth section. The film 23 is etched by gas plasma which does not affect the influence to a substrate or wiring metal, thereby foring an air bridge in noncontact. After lower layer wiring metal 31 is formed by normal photolithographic and lift-off methods, a photoresist (OFPR-800) is formed on the entire substrate. A resist film 33 is allowed to remain only on the crossover of the upper and lower layer wirings forming the air bridge by the lithography and the peripheral regions, and baked at 200 deg.C for 20min. Then, upper layer wirings 32 are formed by the method equivalent to the lower layer wirings. The film 33 of air bridge structure is removed by plasma etching with oxygen gas an air bridge.

Abstract: PURPOSE:To obtain vivid image quality which has excellent contrast for a long time by providing a means for removing developer at least over the entire periphery of the surface of a developer carrier every time an image is recorded on a specified number of sheets. CONSTITUTION:This device is provided with the means 9 for removing the developer 8 over the entire periphery of the surface of the developer carrier 1 every time the image is recorded on the specified number of sheets. Namely, a means 10 is provided, which performs solid black development to the developer 8 on an electrostatic latent image carrier 6 only while the developer carrier 1 rotates at least once when recording is not performed. Therefore, the developer 8 corresponding to a non-image area is surely transferred to the carrier 6, and fogging on a recording paper which occurs because the developer 8 is flocculated and stuck to the developer carrier 1 is prevented from occurring. Thus, the vivid image quality which has excellent contrast for a long time is obtained.

IPC: H02J3/38
Filed: 1993-02-18
Abstract: PURPOSE:To use a semiconductor switch in which a voltage between poles is twice or less as large as a system voltage. CONSTITUTION:An instantaneous voltage drop compensator 1 connected between a system A side and a non-utility generator G side uses a semiconductor switch SS in which a voltage between poles is twice or less as large as a circuit voltage, and connects in series with a breaker CB. When the system A side is instantaneously power interrupted to open the switch SS, the voltage between the poles is detected by a detecting.operator 2, a ratio to its time is measured, an open command is output from a sequencer 3 to the breaker CB by expecting a time delay until the breaker CB is actually opened so as not to exceed the voltage between the poles of the switch, thereby preventing damage of the switch SS having twice or less of the voltage between the poles as large as a circuit voltage. Then, complete opening of the breaker SS is detected, a close command is output to the switch SS for next connection.
