Title: Processing circuit for time axis
Inventor: KOBAYASHI YASUO
IPC: H03K4/90
Filed: 1979-04-23
Abstract: PURPOSE:To increase the linearity of the integrated waveform, by using the non- linear reactance element. CONSTITUTION:The resistor 2 and the varactor diode 3 constitute the integration circuit. Further, when the step voltage 1 is fed to the input side, the varactor diode 3 is charged up, and since the capacitance value of the varactor diode 3 is reduced according to the increase in the charging voltage, the charging current can linearly be decreased by taking the effect of capacitance reduction as a suitable function of the voltage, allowing to constitute the output voltage Cv as the waveform 4 which linearly increases to the time axis.

Title: Controlling method of hydraulic control valve
Inventor: HIRAMATSU TAKEO
IPC: F16K25/00
Filed: 1983-03-28
Abstract: PURPOSE:To eliminate the possibility of a pressure oil leakage from a hydraulic control valve being closed due to the admission of foreign substances, by opening the valve as far as only a short time and washing away these foreign substances taken in by the valve with pressure oil. CONSTITUTION:This method is one that a solenoid valve 22 serving as a hydraulic control valve opens by only a short time whereby these foreign substances taken in between a poppet 40 and a valve seat 41 are washed away by means of pressure oil. Even if the solenoid valve 22 is made to open in time of being closed, pressure oil in a hydraulic pressure passage 31 flows into a drain oil passage 39 so that a spool 29 moves to the left by dint of energizing force of a spring 34, and the pressure oil flows in a direction shown in a full line, meaning that it takes much time till a high gear clutch 6 gets coupled. Therefore, it will merely do such a way as making the solenoid valve 22 open as far as only a short time that does not damage the function of a torque transfer device attributable to closure of the solenoid valve 22. A pulse period indicating the opened state of the solenoid valve 22 is in a range of 1-3Hz while pulse width (t) is to be determined within a range of 10-30msec.

Title: Leaf spring, installing method of this leaf spring and keyboard device using this leaf spring
Inventor: KUMANO SHINJI
IPC: G10H1/32
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To prevent exertion of influence of the warp even if a leaf spring warps to one side in a free condition. SOLUTION: In a leaf spring 1, compressive force is applied in the lengthwise direction on its both ends, and both ends are respectively supported by support members 2 and 3. The leaf spring 1 is deformed in an S shape so that one position of both ends and a lengthwise directional intermediate part respectively becomes nodes N1 to N3 and respective positions between one position of the lengthwise directional intermediate part and both ends become a belly. Therefore, the leaf spring 1 respectively energizes a pair of support members 2 and 3 outside in the lengthwise direction. In this case, even if a warp is caused in the leaf spring 1 in a free condition, influence of the warp is relieved by a movement of the node N3, and always constant energizing force is generated.  Since the leaf spring 1 formed in an S shape increases outward energizing force by upward and downward two warps, even if a thickness of the leaf spring 1 is thinned, necessary energizing force can be obtained.
