Title: Diagnosis method and apparatus for deterioration of article
Inventor: HONJO KATSUHIKO
IPC: G01N29/44
Filed: 1988-05-30
Abstract: PURPOSE:To search securely at the same time a deterioration degree of a structural substance or article in a constant shape and a tension applied to them by calculating the resonance frequencies of a vertical and a horizontal vibrations for the article. CONSTITUTION:An object 5'' to be tested is vibrated with the vibration applied by a vibrator 7. In this case, the bar-shaped object 5'' to be tested is vibrated in a composite style of both vertical vibration (having a displacement mode vertical to the long side direction of the rod) and horizontal vibration (having the displacement mode parallel to the long side direction of the rod). Then these mechanical vibrations are converted to electrical signals by a vibration sensor 1' and amplified by an amplifier 2. The resonance frequencies of the horizontal and vertical vibrations on the object 5'' to be tested are calculated in an arithmetic part 3'' basing on vibration waveforms obtained through the amplifier 2. Next, in the arithmetic part 3'', the tension and the deterioration degree for the object 5'' to be tested are calculated basing on the resonance frequencies of the horizontal and vertical vibrations calculated in accordance with the applied tension and the deterioration degree for the tested object, the diameter, young factor, and density of which are already known. Then, the results obtained in the arithmetic part 3'' are indicated on a display part 4.

Title: Electric characteristic measuring method for semiconductor device
Inventor: YAGI TAKASHI
IPC: G01R31/26
Filed: 1988-05-30
Abstract: PURPOSE:To eliminate need for facilities and a jig for high temperature and to shorten an overall measurement time by making a transistor(TR) in the semiconductor device generate heat by itself. CONSTITUTION:The emitter terminal 4a of the internal TR 4 of the semiconductor device 1 to be measured is led out as the output terminal 1b of the device 1 and connected to a load resistance 6 through a switch 5. The power terminal 1c of the device 1 is connected to a power source 7. At first, in a test 1, the switch 5 is opened to obtain a value A by a measuring instrument 2. Then, in a test 2, the switch 5 is closed to supply a load current to the TR 4, which generates heat by itself. At least, in a test 3, a value B is obtained by taking a measurement similarly to the test 1. Then (B-A) indicates heat dependency with temperature as the electric characteristics. Electric power Pd cleared by the TR 4 is a value obtained by dividing the product of the saturation voltage of the TR 4 and the potential at the terminal 1b. The current temperature rise of the body 1 to be measured is determined by the electric power Pd and test 2.

Title: Positioning control device
Inventor: KAZAMA TSUTOMU
IPC: G05D3/12
Filed: 1985-06-18
Abstract: PURPOSE:To fix a machine to be controlled on the final machine position rapidly by controlling the position of the machine of controlled system on a moving position corresponding to a position command data on the basis of a control signal from a dead zone forming means. CONSTITUTION:If the machine 8 goes pass alpha pulses when a position command circuit 1 is '0', a positional deviation calculating circuit 2 outputs a positional deviation corresponding to alpha pulses having the reverse polarity to the preceding ones. A dead zone forming circuit 11 outputs (alpha-gamma) pulses by the inverted polarity from a polarity holding circuit 10 if the number of pulses to be cancelled is gamma. At that time, a motor 4 moves within the backlash of gears so as to be continuously inverted until moving by (alpha-gamma) pulses. If the machine 8 goes past betapulses by the ivnersion, the circuit 11 outputs (beta-gamma) pulses similarly so that the motor rotates forwards by (beta-gamma) pulses. Repeat of said operation makes it possible to attenuate the drift of the machine 8 forcedly within the backlash. Finally, the machine 8 is stably stopped on a position within the number of pulses to be cancelled.

Filed: 1989-05-24
Abstract: PURPOSE:To easily manufacture a pressure sensor having superior reliability by providing a pressure sensitive element between an inner and an outer electrodes, arranging these element and electrodes coaxially, and using a variable resistor as said pressure sensitive element. CONSTITUTION:An inner electrode 3 is provided along the central axis of an outer electrode 2 of a hollow pipe. A pressure sensitive element 4 is interposed between these electrodes 2,3. In other words, the inner electrode 3, pressure sensitive element 4 and outer electrode 2 are arranged coaxially, so that the detecting sensitivity is never changed even when the pressure is applied to the sensor from a different direction. Moreover, a variable resistor which changes the resistance value in accordance with the pressure is used for the pressure sensitive element 4. Therefore, it becomes possible to obtain a detecting voltage Vs corresponding to the applied pressure. If some pressure is added to the pressure sensitive element 4, it can be cancelled by suitably processing the detecting voltage Vs. Accordingly, a non-directive pressure sensor with superior reliability can be manufactured easily.

Filed: 1996-05-28
Abstract: PROBLEM TO BE SOLVED: To detect the position of a moving table at a low cost by providing a photoelectric sensor facing the position where a roller in a roller chain is passed. SOLUTION: When an elevating/lowering table 5 occupies three positions, i.e., the vertical stop position, the acceleration/deceleration position, and the over-run position, the number of rollers to be counted by a photoelectric sensor 8 is inputted in a sequencer in advance, and the photoelectric sensor 8 is fitted so that the rollers of a roller chain 3 are passed. The light emitted from the photoelectric sensor 8 hits a roller part of the roller chain 3 and is reflected, but not reflected between the rollers. Because the interval between the rollers is constant, the distance of movement of the roller chain 3 and the position of the elevating/lowering table 5 as the moving table can be calculated in the same manner as the pulse of an encoder.
