Title: Internal highway loopback test system
Inventor: MURATA KOICHI
IPC: H04J3/14
Filed: 1987-12-28
Abstract: PURPOSE:To perform self-diagnosis even when a fault is generated by setting internal loopback on an internal highway in a signal device which performs the transmission of a signal by time divisional multiplexing. CONSTITUTION:When the fault of a circuit, etc., is generated and the loopback is performed in the inside of the signal device, a delay circuit 8 delays the signal by the signal set from a control circuit 1 via a delay setting designation line 104. Simultaneously, a selector 9 selects the side B of an input terminal by the signal inputted via a loopback designation line 103. Thereby, the signals delivered from signal transmission circuits 21-2n are time divisionally multiplexed at a multiplexing circuit 3, and are inputted to a separation circuit 6 via a transmission multiplex highway 101, the delay circuit 8, and the selector 9. The separation circuit 6 separates the signal, and delivers them to signal reception circuits 71-7n. Thus, it is possible to perform the segmentation of a faulty circuit easily by the self-diagnosis by changing an opposite circuit by the loopback.

Title: Hydraulic cylinder with built-in stopper mechanism
Inventor: KOSEGI NOBUHIRO
IPC: F15B15/24
Filed: 1994-11-22
Abstract: PURPOSE: To adjust stroke in open loop control by rotating an adjusting dial and providing a built-in stopper mechanism which mechanically stops a piston according to the rotation of the dial and driving the adjusting dial by a stepping motor through a belt. CONSTITUTION: When the rear end of a sleeve 3 is located forward more than the rear end of a piston 5, if the piston 5 advances, the piston rod 6, which meshes the sleeve 3 through threads, advances to the position, where the sleeve 3 abuts on a stopper 4, and stops. Since the sleeve 3 can be moved to any position by turning an adjusting dial 1, stroke can be adjusted by turning the adjusting dial 1. Since the piston 5, when retracted, abuts on a rear body 8 and stops, stroke is not adjusted for retraction. By this constitution, stroke for advance is adjusted by turning the adjusting dial 1.

Inventor: AGA MASAMI
IPC: B62D6/00
Filed: 1991-11-19
Abstract: PURPOSE:To provide a power steering device for obtaining a proper steering feeling even when traveling on a bad road. CONSTITUTION:In the ordinary case where the road surface is not bad, an electromagnetic flow rate throttle valve 96 is closed or the opening degree is kept min., and a steering gear box 46 can not be shifted or hardly shifted for a steering wheel 10, and the steering wheel 10 and a steering wheel 34 revolver in correspondence nearly in 1:1.

Accordingly, even if the steering wheel 34 is turned in vibration form by the unevenness of the road surface, the transmission to the steering wheel 10 is lightened by the vibrational shift of the steering gear box 46, and the steering feeling can be improved.
