Title: Ink jet recording device
Inventor: SAITO KOICHI
IPC: B41J2/06
Filed: 1989-07-19
Abstract: PURPOSE:To increase the use efficiency of an electric field and reduce a voltage applied to an electrode by charging ink in an ink feed path and generating an electric field for ink discharge control at an electrode for ink discharge control provided near an ink nozzle. CONSTITUTION:Ink is negatively charged by supplying a negative charge to the ink using an ink charging electrode 12 in an initial state. The ink charged by the ink charging electrode 12 runs in an ink discharge outlet direction, reaching a position near an ink discharge control electrode 13. No potential difference is present between the ink discharge control electrodes 13, 14 during ink discharge, and the charged ink 11 is discharged from an ink nozzle 10 without receiving an electric resistance by shifting the electrodes by a potential equal to an ink charging potential. When ink discharge is controlled, a potential difference is provided between the ink discharge control electrodes 13, 14 so that the electrode 13 becomes negative and the electrode 14 becomes positive.

Title: Rotor of centrifugal machine
Inventor: ONO HIROSHI
IPC: B04B9/08
Filed: 1987-07-24
Abstract: PURPOSE:To prevent generation of vibration due to looseness of a jointing member and to improve safety by utilizing elastic force of a washer interposed to the upper part of the jointing member and fixing a rotor body to a driving axis. CONSTITUTION:When a rotor body 5 is fixed to a driving axis 2, looseness of joint of the rotor body 5 and the driving axis 2 is inhibited by elastic force of a washer 12 such as a corrugated washer and a cup spring interposed between the cover holder part of the jointing member 10 and the top part of the rotor body 5. Further in case these both are not jointed, the lower end part of the jointing member 10 does not reach the recessing part of the driving axis 2 and a gap is formed between the lower end part and the upper part of the driving axis 2 and therefore it can be easily judged by visual inspection. By such a way, forgetfulness of clamping and looseness of the screw for fixing the rotor body 5 to the driving axis 2 can be prevented.

Title: Method of detecting termination in semiconductor wafer etching system and device
Inventor: PEETERU ETSUBINGU
IPC: G01B11/02
Filed: 1989-07-19
Abstract: PURPOSE: To surely and quickly detect the etching terminating point of a semiconductor wafer etching system, by scanning the surface of a semiconductor wafer with a narrow converged radiant energy beam, and analyzing a reflected beam by parking the radiant energy beam on a parking spot decided from the reflected beam. CONSTITUTION: A wafer 10 is scanned with a laser beam spot 10 along a route 20 in a chip position. The width (w) of a spot 18 is made remarkably smaller than the width W of an opening, such as the scribed line S of a photoresist layer 36. The parking spot P in a flat area 38 on the wafer 10 is decided from the reflected part of the beam at the scanning time. Then, the beam is parked on the spot P and the reflected part of the beam is analyzed by keeping the beam on the spot P during the remaining time of an etching process. As a result of the analysis, the time when a silicon dioxide 34 is completely etched off is decided from the appearance of the flat section of the intensity curve of the reflected beam. Therefore, the etching terminating point can be detected surely and quickly.

Abstract: PURPOSE:To make abrasion resistance and surface quality excellent by forming an overcoat layer in such a manner that a mixture of global inorganic particulates having an average particle diameter less than a predetermined value and metal organic substance which forms glass at the time of baking is coated on the surface of a member and baked. CONSTITUTION:When an overcoat layer is to be made, since global inorganic particulates having an average particle diameter 0.1mum or less is used, the multiple particulates sinter each other with a comparatively low temperature. Metal organic substance forms glass at the time of baking. Accordingly, when a mixture of the inorganic particulates and the metal organic substance is coated on the surface of a member and baked by a proper temperature, the overcoat layer is formed by blocks of the particulates formed by sintered multiple particulates and the glass which fills gaps between the blocks and functions as an adhesive between the blocks, so that abrasion resistance and surface quality will be excellent. The metal organic substance includes a metal element selected out of Si, Pb, Bi, Sn, and the global particulate is selected out of borosilicate glass, SiO2, ZrO2, Al2O3, Ta2O5, TiO2.

Title: Foil-wound transformer
Inventor: HASHIZUME KENICHI
IPC: H01F27/18
Filed: 1981-11-25
Abstract: PURPOSE:To quickly detect the choking in an insulator pipe and prevent troubles  due to raised coil temperatures by a method wherein a bubble detector is installed on an insulator pipe located at the refrigerant outlet side of every refrigerant duct. CONSTITUTION:Every one of the insulator pipes 12' located at the outlets of regrigerant ducts 6 is provided with a bubble detector 15. A local choking in a regrigerant duct 6 or in an insulator pipe 12 located at the refrigerant inlet results in reduction in or disappearance of the quantity of the running refrigerant. Under such a condition, the temperature rises of the refrigerant, finaly causing the liquid to boil. Even a trace of refrigerant running therein generates bubbles as it boils, which arrive at a bubble detector 15 to be detected. The choking bringing about the complete stoppage of liuid flow results in a situation where bubbles under own buoyancy rise in the insulator pipe 12', to arrive at a bubble detector 15. The bubble detector 15 upon sensing a bubble warns of choking in the concerned refrigerant duct or in the insulator pipe 12 at the inlet to the concerned refrigerant duct 6.
