Title: Idle hand-off control method in mobile communication system
Inventor: KIN KEIDAN
IPC: H04W60/04
Filed: 1998-07-22
Abstract: PROBLEM TO BE SOLVED: To reduce battery power consumption in a mobile station, to improve the communication efficiency of an inverse direction control channel and to attain the effect of increase in a call reception rate or the like by decreasing the number of times of idle hand-off operation in a mobile communication system. SOLUTION: A mobile station 20 retrieves a 1st pilot channel with a strongest electric field strength sent from any of many base stations 101-10N and measures the strength and obtains a variable threshold level, based on the strength. Furthermore, a paging channel of lots of adjacent base stations 101-10N synchronously with the 1st pilot channel is monitored and a strength of a 2nd pilot channel sent from any of them is measured. A difference from the strength is obtained by subtracting the strength between the 2nd pilot channel and the 1st pilot channel. Then whether or not the difference is larger than the variable threshold level is discriminated. Then execution of idle hand-off over a mobile base station is controlled depending on the result.

Title: Metallic ornament with fingerprint and manufacture thereof
Inventor: ISHIWATARI AKIRA
IPC: C25D1/00
Filed: 1989-08-11
Abstract: PURPOSE:To reproduce accurately and exactly precise patterns represented by fingerprints on precious metal like silver and gold by taking fingerprints on mold like silicone rubber and by obtaining a product with an electric casting or forming a mold with an electric casting. CONSTITUTION:Fingerprint is taken on clay, silicone rubber and plaster wax prepared in advance. Silicone rubber is particularly desirable simply because fingerprints can be accurately reproduced. Besides in thin type ornaments, when the silicone rubber is made not more than 2mm in thickness, the silicone rubber is the most suitable for reproducing fingerprint on the plane. Next after processing the surface with a sensitizer, silver mirror reaction or vacuum deposition technique treatment is applied and then electric casting is conducted. Thus it is possible to obtain a precisely reproduced mold. When a metal mold is formed so as to function as a mold, it becomes possible to produce a plurality of precise products when a press mold is manufactured with an electric casting with a hard nickel electric casting or by the application of an electric casting.

Title: Four-wheel steering device for vehicle
Inventor: FURUKAWA OSAMU
IPC: B62D7/15
Filed: 1987-08-20
Abstract: PURPOSE:To make the steering ratio of rear wheel with respect to front wheel variable according to the vehicle speed, by converting the rotation of a rotary shaft interlocked with a front wheel steering mechanism through a steering ratio changing mechanism which is operated by means of an actuator being controlled corresponding to the vehicle speed. CONSTITUTION:In a rear wheel steering ratio changing mechanism 25, if an output shaft 16 is concentric with an input shaft 14, rotation of the input shaft 14 does not cause rotation of an yoke member 17 around the axis of its shaft 19, thereby a tierod 35 is not moved to the right/left and only the front wheel is steered. Upon variation of vehicle speed, a rear wheel steering controller 31 receives signals from a vehicle speed detecting means 32 and a position detecting means 33 to drive a motor 26. Consequently, a rolling member 22 rotates around a shaft 23 and inclines back and forth. Inclination of the rolling member 22 causes inclination of the output shaft together with the yoke member 17 so as to vary the steering angle of rear wheel.
