Title: Time division communication system for mobile communication
Inventor: ITO SADAO
IPC: H04B7/26
Filed: 1990-09-17
Abstract: PURPOSE:To construct a system strong against interference disturbance by shifting automatically a time slot to the time slot of longer guard time when radio interference arises and communication quality is deteriorated, and if the time slot can not be shifted, narrowing the width of the time slot by lowering highest frequency by a low pass filter. CONSTITUTION:An interference disturbance detector is installed previously in mobile radio equipment or a radio base station, and when it is detected that the disturbance arises, the time slot during communication is changed successively to the slot of the longer guard time. If it is impossible because of the congestion of traffic, the low pass filter is inserted in respect of a signal to be inputted to a signal velocity conversion circuit 51a. Simultaneously with this, an instruction to increase time compression ratio (1/n) 2.4/3.0-times higher than 1/n in the past is given to the signal velocity conversion circuit 51a-1. The guard time between the time slot SDa-1 and the time slot immediately before it is greatly increased, and the radio disturbance to the time slot SDa-1 due to multi-frequency propagation is greatly reduced.

Inventor: TOKI SOUTAROU
IPC: C25D3/46
Filed: 1983-12-26
Abstract: PURPOSE:To obtain both of a dull surface and bright surface with the same plating liquid by depositing the silver having the dull surface by using a dull silver plating liquid, stripping the strike plating by an anodic electrolytic treatment and forming at the same time the partial silver plating surface into a bright surface.

Title: Information processor and information input method
Inventor: SAKAGAMI YASUHIKO
IPC: G06F3/033
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To reduce the failures and to improve the reliability of an information processor with its simplified and thinner structure by preparing the 1st and 2nd touch pads which have the same basic structures and detecting the contact of a finger on the 2nd touch pad while detecting the movement of the finger contact position on the 1st touch pad. SOLUTION: When a user moves a pointer 5 to a prescribed position, he touches (presses) a prescribed position on a touch pad 12 with his finger and moves the contact position in the moving direction of the pointer 5. Since a click operation is inputted on a touch pad 31, it is not required to detect an operated position of the pad 31 and accordingly it is enough just to detect whether the pad 31 is operated or not. The pad 31 has the same basic structure as the pad 12 and can be basically detected only by a contact with no stroke operation (deep press operation) required for turning on a switch.
