Title: Substrate rotating type surface treatment
Inventor: TANAKA MASATO
IPC: C23C16/52
Filed: 1990-11-06
Abstract: PURPOSE:To eliminate the difference of surface treatment speed between the central part and the peripheral part of a substrate to be processed, and realize uniform surface treatment over the whole region of the surface of a substrate to be processed, by performing the surface treatment using the number of revolution at which the magnitude relation between the surface treatment speed in the central part and that of the peripheral part of the substrate to be processed is reversed. CONSTITUTION:When the number of revolution of a substrate W increases, the central part of the substrate W is etched more intensively than the peripheral part. The etching degree of the central part and that of the peripheral part of the substrate W is reversed at 250rpm, and the etching depth becomes nearly uniform all over the surface of the substrate W. On the basis of the above result, the substrate W is subjected to etching process while rotated at 250rpm, wherein the magnitude relation between the etching speed of the central part and that of the peripheral part of the substrate W is reversed.

Title: Dummy base station for portable terminal, call limiting system using the same and call limiting method therefor
Inventor: NISHIMURA SOUYU
IPC: H04W48/04
Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To apply the call limitation of a portable terminal in a specified area to an existing portable terminal as well while suppressing a cost. SOLUTION: In a call inhibition area 60, this dummy base station 10 not connected to a public network 40 and provided with only the function of turning an adjacent portable terminal 30 to the standby state of a local station is installed. The portable terminal inside the call inhibition area is turned to the standby state of the dummy base station and disconnected from the public network. When a call is made from a fixed terminal 50 through the public network to the portable terminal, a base station 20 sends incoming call signals to the portable terminal, however, the portable terminal does not respond to the base station 20 since it is turned to the standby of the dummy base station, termination call sound is not rung and communication can not be performed.  In the case of trying to make a phone call from the portable terminal to the fixed terminal oppositely, the dummy base station does not respond to the calling request of the portable terminal and the communication becomes impossible likewise.

Title: Sleeve for assembled sleeve type crown control roll
Inventor: ISHIKAWA TOSHINORI
IPC: B21B27/05
Filed: 1989-11-22
Abstract: PURPOSE:To reduce resultant tensile stress on the surface of sleeve by applying compressive residual stress to reduce superposing action with the acting stress of oil pressure that is worked to a hydraulic chamber between the inner surface of sleeve ad the outer surface of shaft. CONSTITUTION:A sleeve 1 is shrinking fitted on a shaft 2. When working in a rolling mill, crown control is done by expanding the sleeve 1 by applying oil pressure to the hydraulic chamber 3 through hydraulic holes 4 which are bored in the shaft 2. By performing the heating by low-frequency induction heating when the sleeve 1 is quenched, it is easy to make a heated layer thicker and to restrain the heating-up of the inside. Therefore, deep quenching hardened layer is obtained and also larger compressive residual stress than using conventional technique can be given on the sides of both the inner and outer surfaces of the sleeve. Resultant tensile stress on he surface of sleeve can be reduced less than a half.

Title: Perfume retaining agent for picture
Inventor: KIYOHARA ICHITA
IPC: B44D2/00
Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To manufacture pictures that appeal not only to the sense of sight, but also to the sense of smell by dissolving oil perfume in an oil solvent, and further adding a dammar resin are required. SOLUTION: In an oil perfume, the perfume of a lavender or rose is used for bringing tranquillity and relaxation atmosphere, and a perfume of lemon or jasmine is used for rise of feelings. These oil perfumes are used such that they are dissolved in an oil solvent of a vegetable dried oil such as linseed oil, tung oil and bean oil, or petroleum such as dried petro. As required, it is used by being added with dammer resin in order to adjust its viscosity or keep perfume retainability. Thus, a picture perfume retaining agent consisting of each component is used in addition to oil painting colors, and forms a picture surface that gives perfume retainability continuously. When a perfuming property is weakened or lost with ages, the perfume retaining agent is applied or sprayed on the surface after a perfume base is thinned with retouch varnish, thereby allowing a perfume effect to continue.

Title: Electronic sunglasses
Inventor: YAMASHITA YOKO
IPC: G02C7/10
Filed: 1989-11-21
Abstract: PURPOSE:To eliminate the need for switching from the outside by using a solar battery as a power source and an optical sensor and providing an oscillation circuit which is operated by the brightness of incident light to change the color of a liquid crystal panel and a delay circuit which transmits a change in the brightness of the incident light by delaying the same. CONSTITUTION:The solar battery 1 acts as the optical sensor and is operated by the brightness of the incident light to generate a voltage which is sent through the delay circuit 2 to a voltage detecting IC 3. The oscillation circuit is turned on and a CC oscillation circuit 4 is operated by the IC 3 when the voltage exceeds a specified voltage. The color of the liquid crystal panel 5 is darkened by the operation of the CR oscillation circuit 4. The voltage is not sent to the voltage detecting IC 3 by the delay circuit 2 and the color of the liquid crystal does not change unless the regulated voltage is generated for a specified period of time. The voltage of the battery 1, conversely, drops and the CR oscillation circuit 4 stops when the incident light weakens. The liquid crystal panel darkened in color is restored to the original pale color by this stop. The liquid crystal is kept dark in color by the delay circuit 2 if the voltage below the specified value does not continue over the specified time at this time. This state is repeated and acts as sunglasses corresponding to brightness and darkness.
