Title: Wheel control system
Inventor: SAKAMOTO HIDEO
IPC: G01P3/489
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To obtain a wheel control system by which a wheel is controlled by automatically detecting the wheel diameter of as many wheels as possible. SOLUTION: On the basis of the rotational speed ωn of a certain wheel and on the basis of the measured wheel diameter Ro and the rotational speed ωo of a specific wheel, a computing circuit 43 calculates a wheel diameter Rn by using Expression 2 so as to be outputted to monitor bodies 41. The monitor bodies 41 in respective vehicles 1 communicate with each other. A monitor body 41a in a vehicle having a wheel transmits the measured wheel diameter Ro and the rotational speed ωo to a vehicle having no wheel. Inversely, it receives the wheel diameter Rn of every wheel. It is not required to measure every wheel diameter, and an effect to automate the control of a wheel is obtained.

Filed: 1991-04-11
Abstract: PURPOSE:To ensure the easy and proper control of a process kit lifetime by causing the positional change of a counter reset member for counting the number of sheets used in the kit via the rotation of a photo-sensitive body. CONSTITUTION:A carriage shaft 15 is supported on bearings 16a and 16b, and caused by a drive gear 14 to rotate. Concurrently therewith, a screw spring 17 rotates, and toner is thereby fed toward a delivery port. The carriage shaft 15 is partly provided with a screw section 18, and a nut 19 is coupled thereto. This nut 19 can travel in the axial direction of the shaft 15, but the rotation thereof is prevented by a retaining member 20. Consequently, the nut 19 travels in an arrow B direction due to the rotation of the shaft 15, and arrives at a position enclosed with a dot line ultimately. In this case, constitution is so made that the count value of a counter is reset, only when the existence of the nut 19 is detected by a sensor 22.

Title: Thermal printing head drive circuit
Inventor: NAMIKI KOJI
IPC: B41J2/36
Filed: 1988-03-31
Abstract: PURPOSE:To obtain a thermal printing head drive circuit requiring a small experimental quantity for obtaining control data and a small storage quantity of memories, by making an image signal holding time constant and the duty of an enable signal variable. CONSTITUTION:Holding times TA, TB, TC for an image signal and a history assurance signal and intermittent pulse information tON are stored in a ROM table 22 of a timing controller 21. Here, the holding time information TA, TB, TC are constant independently of a substrate temperature Tf of a thermal printing head 1 and a resistant value R of a heating resistor. However, an ON time tON of an enable signal depends on the substrate temperature Tf of the thermal head 1 and the resistant value R of the heating resistor. Therefore, if the values Tf and R are changed, the value tON corresponding thereto may be fetched from a memory circuit. In this manner, the need for conducting an experiment with different continuous pulses according to an image signal is eliminated, which enables a smaller experimental quantity and a smaller storage quantity of memory circuits.

IPC: B60G17/00
Filed: 1982-05-10
Abstract: PURPOSE:To obtain operational stability and riding comfortableness by controlling a car height at will in accordance with the running condition of the car. CONSTITUTION:As a solenoid valve 38 is closed usually, when a compressor 16 is driven by an output issued from a control unit 9, a raised pressure is added to an air layer 41. This pressure is transmitted to a hydraulic pressure room 33 through an oil room 40, and pushes a piston 30 to make the car height higher. The pushing up power by the hydraulic pressure acts on the spring power of the spring additionally. When it is required to raise the car height rapidly, a piston 30 moves rapidly by opening a solenoid valve 37 for an instant. When the car height gets to the regulated level, an air compressor 16 is stopped. When it is required to lower the car height, the solenoid valve 38 is electrified and air is released through path 43. Moreover, whether the regulated height is attained or not can be judged by an input of a car height sensor 10.
