Title: Detecting circuit for electrostatic capacity
Inventor: TAKAHASHI OSAMU
IPC: G01R27/26
Filed: 1981-06-01
Abstract: PURPOSE:To reliably detect a capacity of a capacitor to be detected without being affected by a length, a shape and a material quality of a coaxial cable in a detecting circuit for electrostatic capacity in which a detecting circuit and a capacitor to be detected are connected with a comparatively long conductor. CONSTITUTION:A connecting point A, where a non-inversion input terminal of an operational amplifier 9 is connected to a resistance 7, and one end of a capacitor 8 to be detected are coupled to each other with an inner core conductor of a coaxial cable 18, and the outer sheating conductor of the cable 18 is joined to the output of the operational amplifier 9. A distribution capacity 20 exists between the outer sheathing conductor of said cable 18 and a DC power source 1. As noted above, the electric potential of the output of the operational amplifier 9 is equal to that of the outer sheathing conductor of the cable 18, or the electric potential of the inner core conductor of the cable 18 is equal to that of the outer sheathing conductor, and the voltage of the distribution capacity Co of the cable 18 is brought to 0. As a result, no charging current flows to the distribution capacity Co, and this permits ignoring of the influence on the distribution capacity Co. A charge and discharge current to the distribution capacity 20 is supplied from the operational amplifier 9, and thereby the selection of an enough low output impedance of the operational amplifier 9 permits to prevent the distribution capacity 20 from exercising the influence on the capacitor 8.

Title: Converting device of tidal energy
Inventor: OOTSU FUMIO
IPC: F03B13/26
Filed: 1983-05-16
Abstract: PURPOSE:To simplify a converting device, by constituting a converting unit so as to both naturally introduce the air only at low tide and generate compressed air at high tide. CONSTITUTION:At low tide, an upper part to the device main unit is floated on the surface of the water, naturally introducing the air into a pressurized air chamber 22. Introducing ports 24 of the air are closed when the pressurized air chamber 22 is filled with the air. When the tide turns from a ebb to a flow, as the surface of the water rises high the air in the pressurized air chamber 22 is compressed by the pressure of water flowing into the chamber from an opening 26, generating compressed air in the pressurized air chamber 22. Then at high tide, a pressure of the compressed air is increased to the maximum level. If the pressure of the compressed air in the pressurized air chamber 22 reaches the prescribed level, a transfer feed pipe 28 is opened, feeding this compressed air to a device such as electric power generation.

Title: Measured value monitor device
Inventor: KURISU HAJIME
IPC: G05B23/02
Filed: 1989-04-03
Abstract: PURPOSE:To attain monitor and control tasks regardless of an operating state of a stop state of the device to be controlled by performing the comparison between the actual measured value and the upper/lower limit levels set based on the measured value corresponding to a desired control schedule mode and deciding whether the measured value exceeds the upper/lower limit levels or not. CONSTITUTION:A detection means 1a detects the value obtained from the measurement of the data to be monitored, and a register means 8 registers the measured value into a measured value register part 5. Then the measured value is retrieved out of the part 5 via retrieving means 9 based on a desired control schedule mode. Based on the retrieved measure value, a set value arithmetic means 10 calculates the upper/lower limit levels. A comparison means 11 compares the upper/lower limit levels with the measured value of the means 1a. A deciding means 12 decides whether the measured value to be minitored exceeds the set upper/lower limit levels or not based on the result of comparison of the means 11. Thus it is possible to perform the minitor and control tasks in response to the change of the detected measured value regardless of an operating state or a stop state of the device to be controlled.

And the output V2 of the throttle sensor 1 is read into a CPU within the ECU 3 when the valve is fully closed, and the difference DELTAV between the aforesaid output and a reference value is concurrently operated. In the second place, it is judged whether or not the absolute value of DELTAV is less than a threshold value T where the output voltage V2/V1 of the throttle sensor is equivalent to the boundary of a linearity guarantee range, if an unequality ¦DELTAV¦>=T is satisfied, it is outputted that the signal from the throttle sensor is abnormal. Meanwhile, if the unequality of ¦DELTAV¦<T is satisfied, the output V2 of the throttle sensor 1 is read, and an equation of throttle opening = (V2+DELTAV)/V2 is then operated.

Title: Memory device having sense amplifier of over-drive system
Inventor: NISHIMURA KOICHI
IPC: G11C11/409
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To perform the control of over-drive operation of a sense amplifier with an appropriate timing. SOLUTION: The sense amplifier is over-driven at least in the first period by switching a drive power source Viid of a sense amplifier from a first power source Vdd having a first potential to a second power source having lower potential than the first potential. And, the timing with which the power source is switched from the first power source to the second power source, is controlled conforming to a potential of a dummy bit line driven by a sense amplifier for monitor. That is, the drive power source Viid of the sense amplifier is switched from the first power source Vdd to the second power source with timing 2 at which a potential of a dummy bit line of a H level reaches a potential of a second power source.  Even if the potential of the first power source Vdd is varied and the drive speed of a sense amplifier of a over-drive system is varied, the drive power source Viid of the sense amplifier can be always switched to the second power source with an appropriate timing.
