Title: Optical signal receiver
Inventor: KONNO HARUO
IPC: H04B10/50
Filed: 1985-10-22
Abstract: PURPOSE:To obtain the signal output of a high output, which is excellent in its frequency selecting characteristic, by connecting a fitter element in parallel to the load resistance of the photodiode of the photodetector of an optional signal, forming a resonance circuit and making the modulating signal frequency of light coincide with the resonance frequency of the resonance circuit. CONSTITUTION:A ceramic filter element 7 is connected in parallel to the load resistance 3. An equivalent circuit when a photodiode 1 side is seen from the input terminal of an amplifier 2 forms a resonance circuit, and when the modulation frequency of the optical signal coincides with the resonance frequency of the resonance circuit, the resonance impedance of the resonance circuit becomes extremely high, therefore, the input level of the amplifier becomes higher than an input level when the ceramic filter element 7 is not connected. Accordingly, the level outputted to the output terminal 6 of the amplifier also becomes high, and the sensitivity of this optical signal receiver is improved.

Filed: 1998-08-21
Abstract: PROBLEM TO BE SOLVED: To prevent defects in shape and to improve edge drop by crossing work rolls by a prescribed cross angle and shifting the work rolls so that the edge drop of a metal plate after rolling becomes the target edge drop. SOLUTION: Relating to a 1st stand controller 5, the cross angle where the max. elongation difference rate is smaller than that of the target plate-shape is determined from the predetermined relation between the cross angle and the plate shape and the command value of the cross angle is outputted to a crossing mechanism 4.

Abstract: PURPOSE:To improve the operating ratio of a robot by interrupting the subsequent work at the time when the amount of rainfall detected by a rainfall detecting means is larger than a predeterminate value. CONSTITUTION:A rainfall detecting means 23 and means 11, 13, 16, 24 and 25 which determine the subsequent work mode in accordance with the amount of rainfall detected by this means 23 are provided.

Title: Detecting device for clogging of oil transfer water-cooled cooler
Inventor: TARUMI NOBUO
IPC: H02H5/00
Filed: 1993-09-22
Abstract: PURPOSE:To detect that a cooling pipe is clogged or not in its early stage by a method wherein a water gathering chamber is provided on the upper part of a water intake pipe, and the level of water surface in the water gather ing chamber is detected. CONSTITUTION:When cooling water 13 is spouted out downwards from a pressure control pipe 9, it gathers partially in a sump chamber 11. By this process, a float 12 floats turning around a support pin 18, so that a switch 14 is turned ON. Therefore, leads 15 are short-circuited, and an alarm 21 sounds a buzzer or outputs anomalous signals receiving a contact signal to inform that the cooling pipe is clogged. Even if water gathers in the sump chamber 11, it is discharged out of the chamber 11 a little later through a drain hole 16 provided to the sump chamber 11, so that it is found that cooling water is continuously spouted out from the pressure control tube or not. Cooling water 13 gathered in the sump chamber 11 is not required to be discharged out each time. By this setup, it is judged that cooling water is continuously or instantaneously spouted out from the pressure control pipe, so that it is found that a cooling tube is clogged or not.

The table data of the relation between the temperature and the target potential is set in a target potential setting means 3 so as to obtain the target potential corresponding to the temperature of the drum detected by the surface potential sensor 50. And the voltage of the grid is altered by adjusting the input of a high voltage power source 2 so that the potential detected by the surface potential sensor 50 becomes equal to the target potential. Every time the temperature of the drum changes, the target potential is newly set from the table so as to alter the voltage of the grid so that the potential detected by said sensor 50 becomes equal to the target potential. Even if the temperature of the drum which is the photosensitive body changes, the electric potential of the developing part can be kept constant and recording with high image quantity without fog can be stably executed.

Title: Power failure detecting circuit
Inventor: KONO KAZUTAKA
IPC: G06F1/28
Filed: 1990-09-07
Abstract: PURPOSE:To distinguish turning-OFF of a power switch from power failure to prevent erroneous operation of an electronic machine by providing a first comparator for outputting a power failure detecting signal and a second comparator for continuously sending the power failure detecting signal even after the power is restored. CONSTITUTION:An output of a first comparator 4 is at a low level LL when power failure occurs or an ac power source is OFF, while working current flows to a working coil 6a of a latch relay 8. An ON signal or a reset signal output from a dc power source device 1 is applied to a second comparator 5 respectively from input terminals 12, 13, wherein if the ON signal is input when a contact 7b is open, the output is at LL while reset current flows to a reset coil 6b. When the contact 7b is closed, a reference signal Vr further drops so that the output of the comparator 7 is not at LL even if the ON signal is input and no reset current flows. That is, if contacts 7a, 7b are closed with working current flowing to the coil 6a by detection of power failure and the power is then restored, the output of the comparator 5 remains at a high level and the relay 8 is not set, so that the power failure detection signal is continuously sent out via the contact 7a.

Title: Ultrasonic wave microphone and its frequency adjustment method
Inventor: ODA SHINRO
IPC: H04R17/02
Filed: 1997-09-01
Abstract: PROBLEM TO BE SOLVED: To provide a ultrasonic wave microphone whose resonance frequency is easily adjusted where re-adjustment is attained even when adjustment of the resonance frequency is failed. SOLUTION: The ultrasonic microphone is made up of a cylindrical vibration case 1, a diaphragm 2 forming the bottom of the vibration case 1, a piezoelectric element 3 fitted to an inner face 2a of the diaphragm 2, an insulation plug 8 sealing an opening 1b of the vibration case 1, and a lead pin 4 connecting to an electrode of a positive side face of the piezoelectric element 3. Thus, the resonance frequency is easily adjusted in a short time at an inexpensive installation without cutting the diaphragm 2 by removing part of the lead pin. Furthermore, in the case that the frequency adjustment is failed, since re-adjustment is attained by replacing the lead pin excessively cut off with other lead pin and generation of a defective microphone is prevented.  Since the weight of the lead pin 4 acts like an added weight to increase the amplitude at resonance comparatively larger, the sound pressure characteristic is enhanced.
