Title: Earthquake detection apparatus
Inventor: SAITO HIROYUKI
IPC: G01P15/18
Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To derive an earthquake detection signal when an energy density of an earthquake wave corresponding to the degree of damages by the earthquake is large. SOLUTION: Acceleration sensors S1, S2 derive outputs having one polarity and the other polarity corresponding to a capacitance change when a semiconductor single crystal silicon is etched and a vibrator is shifted by an earthquake wave. Absolute value circuits 1, 2 obtain absolute values of the outputs of the acceleration sensors and, level discrimination circuits 5, 6, 9 discriminate levels. Only a large acceleration is detected accordingly. Low pass filters 19-21 filter outputs of the level discrimination circuits 5, 6, 9 of approximately 0.1-10 Hz which is a range including a frequency of the earthquake wave, and feeds the outputs to an up/down counter 33. While the earthquake wave is within the frequency range, pulses of 400 Hz from an oscillator 28 are counted up. The pulses are counted down in other cases.  When the counted value is not smaller than a reference value, the earthquake wave is judged to have a large energy density, whereby an earthquake detection signal is derived.

IPC: H01H47/04
Filed: 1983-03-30
Abstract: PURPOSE:To contrive the miniaturization, the reduction of electric power consumption, the low noise and the reduction of release time by controlling the coil driving current by the semiconductor circuit. CONSTITUTION:A circuit composed of a diode 10, a surge absorber 9 and a transistor 11 for flowing a fly-wheel current is connected to a coil 3 of the electromagnet device in parallel.

Title: Electrophotographic sensitive body
Inventor: FUKAGAI TOSHIO
IPC: G03G5/047
Filed: 1987-03-09
Abstract: PURPOSE:To enhance sensitivity and to lessen the degradation in electric chargeability arising from pre-exposing fatigue by incorporating crown ether into a layer in which an electric charge generating material is dispersed. CONSTITUTION:An electric charge generating layer 1 and charge transfer layer 2 are successively laminated on a conductive base 3. The crown ether is incorporated into the layer 1 in which the charge generating layer is dispersed. Namely, the crown ether is chemically adsorbed in the charge generating material and provides the recombination center of the charges generated by light absorption and, therefore, the charges generated by the pre-exposing fatigue are quickly recombined and are thereby annihilated, conceivably by which the drop of the charge potential of the photosensitive body is suppressed. The electrophotographic sensitive body which has the high sensitivity, extremely lessens the degradation in the electric chargeability arising from the pre-exposing fatigue and obviates the drop of the charge potential even after repetition of the electrical charging and exposure is thereby obtd.

Filed: 1979-05-04
Abstract: PURPOSE:To reduce the temperature dependency of vibration damping effect by adding a vulcanizing agent and stretching oil to the rubber base comprising FS (silicone rubber) and CIIR (partially bridged butyl rubber) and then kneading them.

Title: Thermally sensitive type residual engine oil detector
Inventor: URYU HIDEKAZU
IPC: G01F23/24
Filed: 1990-03-06
Abstract: PURPOSE:To obtain the residual oil detector which withstands high temperature and has high accuracy and long life and is small in size by forming a platinum thermally sensitive resistor thin film on an enameled substrate as a thermally sensitive resistor for engine oil level detection and also providing a thermally sensitive resistor for temperature compensation on the enameled substrate which supports said resistor. CONSTITUTION:On the enameled substrate 1, the platinum thin film formed by printing platinum paste in specific pattern and baking it is trimmed with laser light to form the thermally sensitive resistor 2 for engine oil level detection. The resistor 2 when dipped in engine oil varies in the heat conductivity of the resistor surface, so the temperature varies. That is detected electrically as variation in the resistance value, but a thermally sensitive resistor 3 for temperature compensation is arranged on the same substrate and dipped in the engine oil at the same time. Consequently, the temperature of the engine oil itself is detected to accurately perform the temperature compensation. A hole is bored in the substrate between the resistors 2 and 3 to preclude thermal mutual interference and the accuracy of the engine oil rest detection is improved.

Abstract: PURPOSE:To prevent the lock-off of a guiding device of a flying object, by switching a signal discriminating circuit and a filter circuit to those of a wide band respectively when a semiactive homing guidance to an active homing guidance. CONSTITUTION:The frequency is converted by mixers 3 and 4 for the reflection signal (a) and irradiation signal (b) which are given from a target. These signals are then mixed by a mixer 8 to produce a video signal, and this video signal receives again a conversion of frequency through a signal detecting circuit 18 to follow up the signal in the form of a narrow band AFC 1oop. Then the semiactive homing guidance is switched to the active homing guidance by he semiactive/active switch signal (c). In this case, a signal discriminating circuit 16 that converts the tracking signal of the circuit 18 into the DC voltage and a filter circuit 17 that limits the signal tracking band are switched to wide band  circuits 35 and 36 by a band switching circuit 33. As a result, the locking mode can be held for the circuit 18 even in the active homing mode.

IPC: H01L21/67
Filed: 1985-03-19
Abstract: PURPOSE:To improve simplification, inexpensiveness, and reliability of mechanism, by rotating wafer with its keeping in contact with a surface by the use of a drive with respective different belt speeds and applying an orientation flat to the surface in order to align a mounting position of wafer. CONSTITUTION:To rotate wafer W, a belt 21a is stopped and a belt 21c is driven. When the orientation flat OF makes contact with a surface 23a, the belt 21c stops driving through the signal of an orientation flat sensor 25, in order to complete an assigned position alignment, that is, pre-alignment. Thereafter, likewise as usual, a carriage arm 1 enables wafer W to be carried and mounted on a stage 2. Hence, composition of mechanism for aligning the position of wafer is simplified, with its inexpensiveness and reliability improvement to be realized.

Filed: 1989-03-08
Abstract: PURPOSE:To attain the most likelihood demodulation by means of a simple constitution by outputting demodulated data with the highest probability from a digital signal sequence by using a storage means such as a ROM. CONSTITUTION:A sampling clock whose phase synchronizes with a recording signal is formed by a phase synchronizing oscillator 8 e.g., to convert the recording signal into a digital signal.
