Title: Steering control device for front-rear wheel steering vehicle
Inventor: ABE MASARU
IPC: B62D7/14
Filed: 1989-04-14
Abstract: PURPOSE:To improve turn stability at the time of sudden braking, sudden acceleration, etc., by detecting a front wheel steering angle and a car speed and determining a target steering angle of a rear wheel while suppressing a change of steering angle of the rear wheel by a car speed in accordance with detected acceleration in the longitudinal direction. CONSTITUTION:Steering ratio K is determined in a steering ratio determining means E being based on a car speed V detected in a car speed detecting means B, and a rear wheel target steering angle thetapr is determined by a rear wheel steering angle determining means D by this steering ratio and a front wheel steering angle detected in a front wheel steering angle detecting means A. Here in accordance with longitudinal directional acceleration G of a vehicle detected in a longitudinal direction acceleration detecting means C, a change of the rear wheel target steering angle by the car speed V is suppressed by suppressing a change of the car speed V detected by a suppressing means F or the steering angle ratio K determined in a suppressing means F' or the rear wheel target steering angle thetapr determined in a suppressing means F''. Thus, turn stability can be improved at the time of sudden braking or sudden acceleration and the like.

Abstract: PURPOSE:To space a platen and a thermal head from each other when the printer is not used and prevent the platen from being deformed, by providing a power switch operating mechanism which operates in conjunction with a thermal head retracting link mechanism simultaneously with a changing-over operation of a power source switch. CONSTITUTION:When a power source switch operating lever 28 is rotated clockwise with a rotary shaft 29 as a center by manually operating a knob member fixed to the outer end of the rotary shaft 29, an upper end part 28b of the lever 28 is spaced from the power source switch 27, thereby turning OFF the switch 27, and a tension coil spring 31 causes the upper end part 28b of the lever 28 to springingly push in a reciprocating member 26a of a solenoid 26 in the direction of an arrow D. By this, the thermal head 14 is spaced away from the platen 15 to a retracted position through a link mechanism consisting of a link member 22, a cam 23, a link member 24 and a supporting shaft 25.

Title: Manufacture of porous carbon plate
Inventor: MURAKAMI SHIGERU
IPC: H01M4/88
Filed: 1991-04-25
Abstract: PURPOSE:To obtain a carbon plate with stable properties by manufacturing a porous carbon plate without impregnating resin. CONSTITUTION:Mixture paper sheets in which rayon fiber and acrylonitrile-type fiber are mixed in weight ratio 60/40 to 80/20 (rayon/acrylonitrile) are layered, heated, and press-molded to give a green molded body and carbonized by sintering. In this way, by eliminating the resin impregnation process, it becomes unnecessary to consider pre-heating by which resin hardening degree is determined and manufacturing processes which affect the properties such as uneven distribution of resin, etc., of a product due to gravity and thus a porous carbon plate having stable properties is obtained.

Title: Bootstrap circuit
Inventor: KUBO HIROSHI
IPC: H03K19/017
Filed: 1982-06-02
Abstract: PURPOSE:To increase the maximum operating voltage of a bootstrap circuit, by providing separately an MIS transfer gate of which a power supply voltage is inputted to the gate. CONSTITUTION:The MIS transfer gate Q4 to the gate and the input terminal of which a power supply voltage VGG and a clock signal phi2 are inputted, is provided to a conventional circuit. Its output terminal is connected to an input terminal 2 of the MIS transfer gate. When the clock signal phi2 of an input terminal 4 is as low as zero V potential, the output terminal 2 goes to a low potential. When the signal phi2 is a high potential, the potential at the terminal 2 is a value of about 2/3 of a power supply voltage E by a threshold voltage of the transfer gate Q4. Since the boost-up of the gate potential of a transfer gate Q2 due to the rising of the signal phi2 to the high potential is suppressed to about 2/3.E in this way, the maximum operating voltage of the bootstrap circuit is increased.
