Title: Float valve
Inventor: OKAMOTO MASAKATSU
IPC: F16T1/24
Filed: 1988-11-09
Abstract: PURPOSE:To secure a large valve opening force by forming a ramp on a valve casing inner circumference at an angle smaller than a tilt angle of a lever. CONSTITUTION:A ramp 20 is installed in a position being opposed to a lever 13 via a float 11. An inclination of the ramp 20 is set to the same direction as that of the lever 13, and the tilt angle is made smaller than that alpha of the lever 13. Buoyancy working on the float 11 surfacing along with the ascent of a level in a valve chest 4 is extended as wedging force and acts on the lever 13. The ramp 20 with an inclination in the same direction as the lever 13 is installed there, whereby a wedging angle comes to a small value made up of subtracting a tilting angle of the ramp 20 from the title angle alpha, the wedging force to be expanded comes to a large one. Therefore a large valve opening is thus securable without enlarging the float 11 and lengthening the lever 13.

Title: Retransmission request system for terminal fault
Inventor: SATO TOSHIO
IPC: G06Q50/00
Filed: 1987-11-11
Abstract: PURPOSE:To facilitate the substitute processing for a terminal fault by attaching an external memory medium to a terminal to record the terminal number, the type of the answer data, the processing result and to send these record contents back to a controller and then sending the record contents to another terminal in case the first terminal has a fault to secure succession of the processing. CONSTITUTION:A data processor consists of a controller 11, a terminal 12 and a card 21. Then the card 21 is put into a card reader part 19 of a terminal 12 for recording the working terminal number. At the same time, the operation of the terminal 12 is possible. The controller 11 checks the data received from the terminal 12 and returns the answer data to the terminal 12. In such a constitution, the card 21 is pulled out of the part 19 and transferred to another normal terminal in case the working terminal 12 has a fault. Then the retransmission of the recorded data is requested to the controller 11 by means of the faulty terminal number. Thus the normal terminal performs the processing based on the received data and completes the substitute processing.

Title: Tracking error detector
Inventor: SHIMOTASHIRO MASAFUMI
IPC: G11B15/467
Filed: 1990-10-23
Abstract: PURPOSE:To improve an error detection accuracy by a method wherein the period of a playback clock is measured. CONSTITUTION:Two playback clocks are generated by phase locked loop (PLL) circuits 8 and 9 in accordance with playback digital image signals. If multiple magnetic heads 2 and 3 having azimuth angles opposite to each other perform playback with a discrepancy between tracking positions following the discrepancy of tracking, the periods of the two playback clocks are shifted to the directions opposite to each other following the discrepancy of the tracking. The frequency of the playback clock from the circuit 9 is divided by a frequency divider 11 and its period is measured by a period measuring circuit 10 with the playback clock from the circuit 8. A deducter 13 deducts a period from a reference period circuit 12 from the data from the circuit 10 to calculate the variation of the discrepancy of the tracking. An initial tracking position is detected by a pilot detecting part 4. The initial position is obtained by an output comparing circuit 18 with a timing signal from a timing signal generating circuit 17. The output of an integral circuit 14 is added to the initial tracking position by an adder 19. With this constitution, an error detection accuracy can be improved.
