Title: Tool abnormality detecting unit
Inventor: YAMANAKA HIDEHARU
IPC: B23Q17/09
Filed: 1981-08-22
Abstract: PURPOSE:To meke it possible to distinguish between an abnormality due to a tol deficit and the expiration of the life of a tool due to abrasion, by providing below the tool a positional detector for measuring a gap between a work piece and the tool so that an alarm is issued when the difference between an original gap value at the begining of the cutting and a gap value during the cutting exceeds a predetermined value. CONSTITUTION:An original gap value ai between a positional detector 6 located below a tool 2 and a work piece 4 upon the begining of the cutting, is stored in a memory 12, and is subtracted from a gap value aii during the cutting. Then, the magnitude of the difference is compared in a comparator 14 with a set value K1, and therefore, an alarm signal is issued when the magnitude exceeds the set value K1. Further, differences each between a final value signal aie upon the completion of working and the original value ai are cumulated, and a signal indicating that the life of the tool is expired, is issued when the cumulated value exceeds a set value K2. With this arrangement, an abnormality due to a tool deficit and the expiration of the life of the tool due to abrasion may be separately detected by only one detector.

Inventor: SUZUKI NORIYUKI
IPC: G01D5/24
Filed: 1995-05-30
Abstract: PURPOSE: To obtain a stable sensor with less malfunction by providing, for example, an electrostatic capacitance type conversion means, first and second delay means, an output generation means, and an adjustment means. CONSTITUTION: A common terminal (a) of switch parts 7a and 7b is connected to a terminal (b). When the width of a pulse b be inputted from a terminal Pe is large, the switch part 7b is controlled, capacitors 7f and 7g are selectively connected to the delay circuit 2 according to the width of the pulse inputted from the terminal Pe to increase the delay time of the circuit 2, thus performing correction so that the phase difference between the circuit 2 and the delay circuit 4 is included within a range of wS-wL.  In this manner, if a phase difference changes when the approach of an object is not detected, adjustment is made a that the phase difference is within a desired range and no phase difference is adjusted when the approach of the object is detected, thus correcting the relatively slow change in the phase difference due to, for example, the change in ambient environment, namely drifting, and hence constantly maintaining a stable detection distance.

Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To enable achieving easy response recovery by embedding each of the thin film electrodes into an insulating substrate with only the surface being exposed, flattening the substrate surface and the electrode surface, and thereby achieving reproduction by polishing. SOLUTION: An electrode pattern 13 is machined in a concave form by minute machining technology or micromachining technology on an insulating substrate, wherein a silicon oxide film is attached to a silicon substrate 12. The entire surface of the substrate is covered by a carbon thin film 14 by a thermal CVD method or a sputtering method. Then, polishing is performed, and the carbon film 14 on the surface is peeled off. Then, only the carbon thin film 14 at the recess part is made to remain, and an electrode is formed. Or, after the electrode pattern 13 is machined in a concave form on the insulating substrate 13, macromolecule solution or macromolecule fused material is made to flow into the electrode pattern 13 formed on the substrate 11. After the pyrolytic carbonization is performed, an electrochemical detector is formed by flattening.  In this way, after the electrode surface is contaminated by the repeated electrochemical measurements, the electrode is polished by using polishing material such as almina and can be used again.

Patent JP-H01303761-A (JP)
Title: Semiconductor device
Inventor: MATSUZAKI HITOSHI
IPC: H01L27/06
Filed: 1988-06-01
Abstract: PURPOSE:To measure a current in flow without resorting to an externally installed resistor by a method wherein a resistance region is built of a high impurity concentration semiconductor in the same semiconductor substrate. CONSTITUTION:In one of the single crystal islands 15 provided in a dielectric isolating substrate 1, a vertical MOS transistor Q1 and a resistor R, composed mainly of a high impurity concentration p-type through-layer 155 and connected to the transistor drain, are formed into one integrated circuit. Upon application of a negative potential to a gate electrode 4 with a source electrode 2 kept positive and a drain electrode 3 negative, an ON state materializes between the source electrode 2 and the drain electrode 3, which shifts to an OFF state upon removal of the gate potential causing a voltage drop though small in a drain current in the p-type through-layer 155. The value of the voltage drop may be taken out at a current sensing terminal 6 through a p-type layer 154. The voltage present at the current sensing terminal 6 is proportional to the drain current because the resistance presented by the p-type through-layer 155 is constant. This design enables the detection of currents without using an externally installed resistor.

Title: Controlling device of ac elevator
Inventor: NOMURA MASAMI
IPC: H02P23/03
Filed: 1986-06-09
Abstract: PURPOSE:To reduce the loss in low speed operation and keep off heat generation to perform stable operation, by thinning out the ignition of thyristers in a specified low speed operating mode. CONSTITUTION:When an operating mode command circuit 10 assigns a normal mode, a gate control circuit 9 performs feedback control so as to operate in rated speed in controlling thyristers T1-T10 corresponding to the firing angle set out in an operation control circuit 8 in proportion to the deviation between the speed command and the speed signal. When the operating mode command circuit 10 assigns a specified low speed mode, the gate control circuit 9 is separated from the operation control circuit 8 and comes up with thinning out the ignition of thyristers. On this account, as the rotating speed is slowed down at 1/2 of the rotating speed of the rotating flux generated inside an induction motor, the slip in low speed operation gets smaller, the loss inside the induction motor is reduced and the generation of heat is kept off.
