Title: Divided bearing sleeve and its manufacture
Inventor: SUGIYAMA SHINICHI
IPC: F16C3/02
Filed: 1985-12-17
Abstract: PURPOSE:To prevent damage through sure adhesion by forming a ring-shaped recess at the outside or inside surface of a divided bearing sleeve body, fitting a pin in said recess in such a way as protruding at one end of the body, coating adhesive at the recess, and affixing an anti-abrasive material followed by finish processing. CONSTITUTION:A ring-shaped recess 2 is formed at the outside surface of a bearing sleeve body 1 divided into halves or segment, and a pin hole 4 is provided in the ring-shaped recess 2 from the end face of said bearing sleeve body 1, and a locating fix pin 3 is fitted in such a way as protruding into the recess 2. Then an anti-abrasive material 5 such as ceramic is formed into circle halves with possibility of fitting in said recess 2, followed by coating of an adhesive 6 over the internal surface 2 of each of these halves or over the surface of the recess 2, and they are bonded fast to then undergo finish processing upon drying the adhesive 6. Accordingly the adhesive layer is uniform to ensure strong bond, and the fix pin does not allow rotation of the anti-abrasive material, which should lead to prevention of wearout of the divided bearing sleeve body 1.

IPC: H02M5/27
Filed: 1990-10-23
Abstract: PURPOSE:To obtain a sine wave PWM, PAM inverter requiring no complex control technology by providing two sets of externally-excited series resonance high frequency sine wave inverters. CONSTITUTION:A rectifier 1 rectifies power of an AC power supply A and feeds first and second high frequency sine wave inverters 2, 3 with DC power. Output (a) of the first high frequency sine wave inverter 2 is added (c) to an output (b) of the second high frequency sine wave inverter 3 and the sum is fed to a full-wave rectifying circuit 4. Conducting direction of an output (d) of the full.-wave rectifying circuit 4 is switched by a switching circuit 5 comprising a bridge inverter circuit based on a switching signal produced at a zero-cross of the output wave-form (d) thus producing a wave-form (e). The output wave- form (e) is then passed through an AC filter circuit 6 for eliminating high frequency components thus feeding a load 7 with an ideal sine wave power (f).

Title: Display and its cleaning method
Inventor: SHIMOBUKIKOSHI MITSUHIDE
IPC: E01F9/619
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To enable the cleaning of adhered oil stains simply by rinsing or light wiping with water and to suppress the adhesion of dust on a display surface by providing the surface of a display base material with a surface layer contg. photocatalyst particles. SOLUTION: The layer contg. the photocatalyst on the surface of the base material is formed on the surface of the display. The surface of the display is made highly hydrophilic according to the photoexcitation of the photocatalyst by having such surface structure. The hydrophilicity of the surface is, therefore, made higher than the lipophilicity. If the surface layer consist of the photocatalyst alone, the photocatalyst is preferably an oxide. Then, the oxide exhibits the hydrophilicity in the state that the contaminants in the environment are not adsorbed thereon and, therefore, these contaminants are expelled by the photoexcitation effect and an adsorbed water layer is formed, by which the hydrophilicity is easily exhibited and a uniform water film is formed.

Filed: 1989-11-02
Abstract: PURPOSE:To smoothly actuate a shaft with an oil film prevented from its break by providing constitution in a manner wherein high pressure oil in an external pressure oil route, flowing in the third connection part, is allowed to partly flow in both turning clearances of the shaft. CONSTITUTION:Since a turning clearance 38 between one end of a shaft 9 and an inner housing 15 (supporting unit) communicates with a port 12 (third connection part), flowing oil therein is allowed to partly flow in the clearance 38 lubricating one end of this shaft. While a flow of oil in the port 12 partly passes through a hollow part 9a of the shaft 9 reaching its another end further generating an inflow in a turning clearance 39 between this another end and a sliding bearing part 30 (supporting unit). Consequently, the shaft 9 is lubricated in its another end. Accordingly, the shaft 9, even when it is placed in a condition at a very slow peripheral speed, is prevented from generating a break of oil film, and bearing performance is obtained. And because the shaft 9 is formed in a hollow shape, the shaft 9 attains the lightness of its weight and improved, responsiveness when it is turned.
