Title: Sensor for liquid level
Inventor: IMASHIRO MINORU
IPC: G01F23/62
Filed: 1985-08-05
Abstract: PURPOSE:To improve measuring accuracy of a liquid level and to lower the total height of a liquid-level sensor by constituting a float so as to move in an inclined direction with respect to a vertical direction to the liquid level. CONSTITUTION:When the liquid level is on the H level, the float 1 is situated near to the upper end part of a case 6 and a magnet 2 makes a reed switch 4a on. Further, when the liquid level is displaced to the L level, the float is moved in the inclined direction downward to the left to make a reed switch 4b on. Hereby, the H level and the L level are detected. In this way, since the float 1 is moved in the inclined direction from the vertical direction to the liquid level with respect to the vertical displacement of the liquid level, the quantity of movement of the float 1 becomes larger than the quantity of displacement of the liquid level and since the detection is performed by enlarging the quantity of displacement by that quantity, the measuring accuracy is improved. Further, since the magnet 2 is provided at the lower side of the float 1, a switch 4a which is long vertically can be provided in the case 6 at the lower side of the float 1 and the total height of the liquid-level sensor can be lowered.

Title: Pulse width modulation type inverter
Inventor: JIYOUFU TOSHIAKI
IPC: H02M7/48
Filed: 1981-10-26
Abstract: PURPOSE:To perform smooth switching in a pulse width modulation type inverter by deciding the switching point from an open loop operation to a closed loop operation in response to the amplifier output signal level of a voltage control system and the output voltage command signal level of a function generator. CONSTITUTION:The amplitude relationship between the signal amplified from an error voltage of a voltage detection signal inputted from a rectifier 5 from the voltage command signal inputted from an A/D converter 8 under the open loop voltage control is monitored by a coincidence detector 23. When the coincidence of the both signals is detected by the detector 23, a contact S1 is opened based on the detection signal, a contact S2 is closed, thereby switching the prescribed voltage control from the open loop to the closed loop operation.

Title: Pulse position measuring type instrument drive circuit
Inventor: NAKAMURA YOSHITO
IPC: G01R29/02
Filed: 1990-06-28
Abstract: PURPOSE:To enable the establishing of an accurate drive of an instrument even under discontinuous conditions of an input pulse signal by measuring a pulse position to control a positioning measurement data output of an instrument pointer at each latch signal formed during the execution of a measurement detecting that they are inputted by a specified number within a specified time. CONSTITUTION:An input pulse signal IN is applied to a terminal 11 to generate a reset signal R and a latch signal G with a pulse control circuit 12. A pulse position measuring counter 13 is operated by a reference clock pulse CP to count and output a measurement value DAT until the signal G is emitted to a latch circuit 14. A pulse edge for the start of measurement is detected with detection circuits 15-17 and data control circuits 18-20 and when there is no pulse edge input with the end of the subsequent measurement, the signal G is applied to the circuit 14 to let a measuring data in by interruption. This reduces a data smoothly prior to the detection of the next edge of the pulse thereby enabling the establishing of an instrument even under discontinuous conditions.
