Patent JP-S63133354-A (JP)
Title: Bearing assembly
Inventor: JIEEMUSU KURIFUFUOODO MACHIYAA
IPC: F16C39/06
Filed: 1987-11-05
Abstract: PURPOSE:To support a spindle without drifting by providing a magnetic circuit to give a stable magnetic force as strong enough to accurately operate the spindle in adding a preload onto a ball bearing assembly. CONSTITUTION:A ball bearing assembly 13 consists of an outer ring race 14 having annular slotted surface facing the radius direction, an inner ring race 12 and balls 18 positioned between both races 14 and 12. The outer race 14 is fitted by contact or pressure to an annular recess section underneath a journal bearing housing 7, and a spindle shaft 5 is compressed into the inner race 12 to pass through a hub 3. A thrust load 4 is put to the inner race 12 while a lifting force 6 is given by a circular magnet 9 to a rotator 15 to lift up the rotator 15. Since this tractive force of the magnet 9 is bigger than the thrust load generated from the total weight of the spindle shaft 5, hub 3 and rotator 15, the inner race 12 is offset upward against the outer race 14, thus lightening the load to the ball bearing 13, eliminating the play among the races 12 and 14 and the balls 18 and hence ensuring that the shaft 5 rotates accurately.

Abstract: PURPOSE:To reduce a cut area of space, by inputting two-axis coordinate positions of plural points on a locus, in which a plane projection external shape of a model is traced by a stylus, to a microcomputer and setting a machining region of closed loop which connects neighboring two points in the trace order. CONSTITUTION:An external shape of a model is traced by moving a stylus along a plena projection shape, and three-axis coordinates of plural points on a traced locus are input to an arithmetic processing unit (CPU)17 from a length measuring device 13 through a length measurement result signal output device 14 and an I/O board (A)16. And the CPU17, in which the measured plural points are connected in a trace order by a straight line or circular arc, sets a machining region of closed loop in a software manner. In this way, an area, cutting space, is reduced as small as possible, and machining efficiency can be improved reducing machining labor hours.

Title: Formation of silicon dioxide thin film
Inventor: OTA WASABURO
IPC: C23C14/32
Filed: 1987-11-06
Abstract: PURPOSE:To form a thin film of silicon dioxide having high light transmittance even on a substrate lacking heat resistance with superior reproducibility by regulating the pressure of an oxygen gas to be introduced into a vacuum tank, grid impressed voltage, and film-forming velocity to values in specific ranges, respectively. CONSTITUTION:A substrate 11 is set, and Si or silicon oxide, such as SiO and SiO2, is held as an evaporation substance by an evaporation source 4. An oxygen gas or a gaseous mixture of oxygen gas and argon gas is introduced at 2X10<-1>-10<-2>Pa pressure into a vacuum tank, and a positive electric potential of 50-300V is impressed on a grid 8 and an electric current is sent to a filament 6. The filament 6 is heated and emits thermions. Then, oxygen molecules or argon molecules and Si are ionized by the above thermions and passed through the grid 8 to undergo further acceleration of ionization. The positively ionized Si is accelerated toward the substrate 11 by the action of an electric field from the grid 8 toward a counter electrode 12 and combines with oxygen midway through the above acceleration or at the substrate 11 surface. By this method, the thin film of silicon dioxide can be formed on the substrate 11 at 1-50Angstrom /sec film-forming velocity.

Title: Production of ceramic diaphragm
Inventor: HIROSHIMA YUKIMI
IPC: H04R7/02
Filed: 1986-11-25
Abstract: PURPOSE:To form a diaphragm for a speaker of high elasticity and large internal loss at a low cost by using an electrode position method. CONSTITUTION:One face of an aluminum substrate of a thickness of about 30mum formed to a diaphragm shape is masked by a resist material and the aluminum substrate is defined to be an anode and an iron plate to be a cathode and impregnated in an aqueous solution such as potassium silicate. Then, a direct current is continuously conducted by maintaining an anode current density to about 1A/dm<2>. While the anode current density is maintained to about 1A/dm<2>, an energizing processing is executed. Thereby, an opalescent ceramic layer composed of silicon oxide is formed on the surface of the aluminum substrate to the thickness of about 10-15mum. An energizing time is determined by considering the thickness of a finally finished ceramics diaphragm. Then, a resist material is removed, the aluminum substrate is impregnated in an acid or alkali solution, dissolved and removed, thereby, the ceramics diaphragm is formed. In such a way, the diaphragm larger in the elasticity than the aluminium substrate can be easily formed with a simple device.

Title: Apparatus for detecting contact resistance of contact
Inventor: ISHIKAWA MINORU
IPC: G01R27/02
Filed: 1987-11-06
Abstract: PURPOSE:To detect the contact resistance of contact during the supply of a main current, by connecting a detection power supply and a current detector in series and connecting this series circuit between both contacts in parallel and detecting the detection current flowing from the detection power supply through both contacts by the detector. CONSTITUTION:A contact 1 is connected to a main electric circuit to supply a main current I to a load. A detection power supply 2 is a high impedance constant voltage power supply and connected to a current detector 3 in series and this series circuit is connected to the contact 1 in parallel. The detection current from the power supply 2 flows not only to a circuit of power source 2-contact 1-detector 3 but also to the main electric circuit but, since the impedance of the main electric circuit is very high as compared with the contact resistance of the contact 1, said current is small and can be neglected. Voltage drop is generated between both terminals of the contact 1 by the current I but, since the power supply 2 is high impedance, the current partially flowing to the series circuit of power supply 2-detector 3 by said voltage drop is small and can be neglected. This power supply 2 supplies constant voltage and the current of the detector 3 is inversely proportional to the contact resistance of the contact 1. Therefore, the contact resistance of the contact 1 can be detected by the detector 3.
