Title: Power steering system
Inventor: KOMAMURA SEIJI
IPC: B62D5/06
Filed: 1977-10-06
Abstract: PURPOSE: To obtain stable steering sense of a power steering system by electrically detecting a vehicle speed proportional to steering resistance accurately and controlling hydraulic fluid supply amount on the basis of the electric signal to always  obtain optimum steering output.  
     CONSTITUTION: When an automotive engine (E) 26 is driven, the exhaust oil of a hydraulic pump P is fed through an input port 8, a variable orifice 0, and an outlet port 10 to the actuator 3b of a power steering unit 2. When the exhaust oil amount increases more than predetermined value to cause the differential pressure after and before the orifice 0 to reach predetermined value, a control spool 5 moves rightwardly against a spring 22 to thereby open a bypass port 9 so as to thus return part of the oil to a tank T. A measuring rod 13 forming the orifice 0 moves leftwardly when the solenoid 30a is urged in response to the vehicle speed signal from a vehicle speed detector 25 to reduce the opening area of the orifice 0 as the vehicle speed increases

Title: Mobile radio communication system
Inventor: YAMANE KENICHI
IPC: H04W36/32
Filed: 1996-05-15
Abstract: PROBLEM TO BE SOLVED: To reduce the number of times of occurrence of hand-over processing caused when a mobile communication terminal moves at a high speed during communication. SOLUTION: Radio base stations 400a to 400c are arranged along a path on which a mobile terminal is movable. In each unit period being a crossing time of a radio zone at an estimated mobile speed by the mobile communication terminal, a radio base station 400b relays s signal line having been relayed to a radio channel on an incoming radio transmission line 300a0 for a preceding unit period by a radio base station 400a to a radio channel on an incoming radio transmission line 300b0, In this case, a frequency band and a time zone of the radio channel in which the same signal line is relayed by the radio base stations 400a, 400b are equal.  Thus, when the mobile communication terminal moves in the incoming direction at an estimated speed, the communication with the same signal line is conducted by using the radio channel of the incoming radio transmission line 300b0 in succession to the radio channel on the incoming radio transmission line 300a0 without hand-over processing.

Title: Displacement transducer
Inventor: NAKAMURA SATORU
IPC: G01D3/02
Filed: 1991-05-28
Abstract: PURPOSE:To eliminate the change of the span and the deterioration of linearity as a result of the transition of a zero point by performing correction and operation so that at least the detecting value of the shifting amount changes linearly in the range of the positive and negative polarities of the differential pressure with the use of a span difference correcting coefficient. CONSTITUTION:This converter is provided with an operating/controlling microcomputer 42. Digital signals are converted to analog signals (direct current) by a D/A converter circuit 43 controlled by the microcomputer 42. Accordingly, a current output of the displacement converter is obtained. Since the D/A converter circuit 43 is able to perform linear D/A conversion, if different two points of the digital output (e.g. 0 and 100%) are adjusted, a current output to a differential pressure  P extending over the positive and negative polarities becomes linear. The chain line is thus corrected. The corrected characteristic includes no turning point over the range of the positive and negative polarities of the differential pressure  P, and represented by a straight line.
