Filed: 1989-01-27
Abstract: PURPOSE:To maintain a shielding effect for a long period of time by covering a plastic frame member formed with a sectional bent contact piece at the end of a mounting piece with a conductive sheet material. CONSTITUTION:A plastic frame member 1 formed integrally with a sectional bent contact piece 12 at one end of a mounting piece 11 to be secured to a housing 3 is covered with a conductive sheet material 2.

Abstract: PURPOSE:To enable high-density recording and information to be erased by including a powder substance capable of exhibiting two or more different photo characteristics by heat hystresis and an organic binder in the recording layer. CONSTITUTION:A recording layer contains a powder substance capable of exhibiting two or more different photo characteristics by heat hystresis and an organic binder. In making recording on an information recording medium in which such a recording layer is provided on a base plate, the energy of lasers, etc., is applied to heat up the powder substance in the recording layer. The powder substance is then cooled quickly to bring about the changes of crystal structure and phase transition to form recorded points. To read out the recorded points, variations in the reflectively and transmissivity of lasers are detected. When the recording layer is heated by application of energy and cooled gradually, the photo characteristics of the powder substance are restored to original state, erasing the recording.

Title: Method of controlling stepless transmission for vehicle
Inventor: ITOU HIROSHI
IPC: F16H63/06
Filed: 1983-02-07
Abstract: PURPOSE:To improve the feeling and performance of operation, by setting the aimed revolution speed of an engine or its aimed speed ratio as a function of the degree of opening of an intake throttle and the speed of a vehicle. CONSTITUTION:The relationship between the degree theta of opening of an intake throttle valve and the aimed revolution speed No of an engine is expressed by using the speed V of a vehicle as a parameter. The aimed engine revolution speed No is defined as a function of the opening degree theta and the vehicle speed V so that at the equal throttle opening degree, the higher the vehicle speed is (V1>V2>V3>V4), the larger the aimed engine revolution speed is. For that reason, the revolution speed Ne of the engine can be increased with the vehicle speed V when an operating person depresses an accelerator pedal. At the low vehicle speed, even if the throttle opening degree is high, the engine revolution speed Ne can be lowered and the change of the aimed engine revolution speed No per prescribed change of the throttle opening degree can be decreased. This results in improving the feeling and performance of operation at the respective vehicle speeds.
