Title: Pressure gauge
Inventor: TSUJIMOTO AKINORI
IPC: G01L9/10
Filed: 1990-03-20
Abstract: PURPOSE:To always provide a pressure change and a signal change with fixed characteristics by fixing a core to be a magnetic body to one end of a transmission spindle fixed to bellows and arranging respective permanent magnets having the same polarity on the inner periphery of a through hole of a diaphragm for supporting the bellows and dividing a high pressure room from a low pressure room and the outer periphery of the transmission spindle. CONSTITUTION:The cylindrical core 35 consisting of a magnetic body is fixed to the leading end part of the transmission spindle 34 fixed on the cylindrical fixing hole 26b and two semi-cylindrical permanent magnets 36 forming N pole on their outer peripheries are fixed on the center part opposed to the through hole 27a of the diaphragm 27. In addition, two semi-cylindrical permanent magnets 37 are fixed to the inner periphery of the through hole 27a so as to be combined with each other like a cylinder. When the bellows 26 is moved in the vertical direction by a pressure difference between the high and low pressure rooms 32, 31, the core 35 is moved in detecting coils 38, 39. Changes in the inductance values of the coils 38, 39 are converted into current changes corresponding to the changes of pressure by an electronic circuit substrate 41.

IPC: B41F13/24
Filed: 1988-03-24
Abstract: PURPOSE:To reduce the displacement of a cylinder, by providing the second bearer outside the bearing of at least one of a pair of cylinders rotated in opposed relationship and providing the auxiliary bearer brought into contact with the second bearer under pressure. CONSTITUTION:Outside the bearings 15 supporting the shaft 14 of a blanket cylinder 2, the second bearers 17 are integrally provided to the shaft 14. An auxiliary shaft 18 is supported in a freely rotatable manner in parallel to the axial direction of the blanket cylinder 2 by bearings 19 and, outside the bearings 19, auxiliary bearers 20 brought into contact with the second bearers 17 under pressure are integrally provided to the auxiliary shaft 18. When the auxiliary bearers 20 are brought into contact with the second bearers 17 of the blanket cylinder on both front and rear sides to apply pre-load to said bearers 17, the force ready to allow the blanket cylinder 2 to approach a plate cylinder 4 is applied to the cylinder middle 11 of the blanket cylinder 2 causing the spring-up after the meeting of gaps 6, 8 to be suppressed. The initial amplitude of the cylinder middle 11 is reduced while the absolute value of the displacement of the blanket cylinder 2 after the meeting of the gaps 6, 8 is reduced to suppress vibration.

Title: Power steering used for vehicle
Inventor: MOMIYAMA FUJIO
IPC: B62D6/00
Filed: 1982-04-23
Abstract: PURPOSE:To reduce fatigue due to steering operation and perform safety running of a vehicle, by always suitably controlling reaction force in accordance with a running condition of the vehicle. CONSTITUTION:At low speed running, a pair of throttle ports 20, 21 of a reaction force regulating valve 15 are never extremely throttled and mutually communicated through reaction communication passages 16, 17, and pressure oil in a reaction chamber 64 of the port is fed to the other reaction chamber 63. Accordingly, the pressure oil in the chamber 64 never causes large resistance for sliding of a control valve spool 51, and steering can be performed by small operative force. At high speed running, a large pressure drop is generated between the upstream and downstream sides of an orifice 35 of a flow control valve 12, and passage sectional area in a communication part between a ring groove 25 of a throttle valve 22 and the ports 20, 21 is decreased to require larger steering force.

Abstract: PURPOSE:To decrease the output offset current by simple constitution by providing the 3rd transistoy (TR) of the same polarity as the lst and 2nd TRs whose emitter is connected to the one collector of the TRs whose base is connected to the other collector and whose emitter is connected to a reference potential point so as to compensate the current decrease due to the base current. CONSTITUTION:The PNP TR Q7 is provided, whose emitter is connected to a collector of a TR Ql, whose base is connected to the collector of the TR Q2 and whose emitter is connected to ground. The emitter current of the TRS Q1,Q2 when the input voltage Vin is zero is made equal to each other and a half of the collector current of the TR Q3. Then the base current of the TR Q7 is added to the collector current of the TR Q2 and the result is fed to the collector of the TR Q4. Thus, the collector current of the TR Q2 decreased by the base current of the TR Q2 is compensated, then the output offset current is very less and the constitution is very simple and practical.
