Title: High voltage power source circuit for electrostatic copying device
Inventor: NEMOTO KAZUMI
IPC: H02M3/28
Filed: 1982-06-24
Abstract: PURPOSE:To obtain a specified voltage in an electric power source for an electrostatic charger which chops a DC power source of a low voltage to AC, increases the voltage thereof with a transformer then obtains the DC of a high voltage by rectification by feeding the secondary output of the transformer through an optical coupler to the primary side. CONSTITUTION:DC 14 is made into AC with a chopper type switching regulator 15 and an oscillation circuit 16, and after the AC is increased in voltage with a transformer 17, the AC is rectified to the DC of a high voltage with a rectifier circuit 21. The current level of the output thereof is extracted as the voltage of a resistor 22 and is amplified with an amplifier 25. The amplified voltage is made into a light signal in a light emission part 27 of an optical coupler and the light signal is fed to a photodetection part 33 on the input side of the transformer, from which the signal is inputted to a differential amplifier 35. The input value is compared with the voltage of a terminal A which is made constant by a limit circuit. As a result, the DC output of the high voltage is maintained at the specified current. The abnormal output of the amplifier 35 is cut off by a Zener diode 38.

Abstract: PURPOSE:To improve the reliability in judgment as to whether reflected light is larger than the lowest amount of light or not by setting the reference lowest amount of light based on the light signal from a light emitting means whose amount can be adjusted in a circuit for judging the lowest amount of light. CONSTITUTION:A light emitting element 12b is provided in addition to a light emitting element 12a for emitting a light beam. The amount of the light from the element 12b is made variable by a light-amount adjusting device 14. The light signal from the element 12b is received by a photodetector 4c. The signal is converted into a voltage signal Vc with a light receiving circuit 21c of a lowest-light-amount judging circuit 5b. The signal is converted into a logarithm signal by a logarithm converter circuit 22c. The difference between this signal and a fixed voltage Vc2 is obtained by a subtracting circuit 23c and becomes a reference voltage for a comparing circuit 29. Meanwhile, the difference between output lnVb of a logarithm converter circuit 22b of a body presence judging circuit 5a and a fixed voltage Vc1 is obtained in a subtracting circuit 23b and becomes the input voltage for the circuit 29. In the circuit 29, the input voltage and the reference voltage are compared. The result of the comparison is latched with a synchronizing circuit 30 based on the clock pulse of an oscillating circuit 10. In this way, the lowest amount of light can be set based on the light signal.

Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To prevent generation of wind throb by stopping tilting up and tilting down at the time of detecting an intermediate tilting position by a detecting means while tilting up and tilting down a tilt roof. SOLUTION: A sensor S1 to detect that a tilt roof 2 is positioned at an intermediate tilt position between an totally closed position and an totally opened position is installed on a base plate of a roof 1. Microswitches S1-1, S1-2 on the sensor S1 are switched and actuated by cam surfaces 16A, 16B of a movable body 16. In the case when the tilt up microswitch S1-1 is switched on, the tilt roof 2 tilts up through the tilt up microswitch S1-1, the tilt up intermediate switch S1-1 is switched off, and it is repeatedly operated on and restarts tilting up. At this time, generation of wind throb is prevented by effectively using an intermediate tilt position PM by this temporary stoppage. The same operation is carried out in the case of tilting down.

IPC: B21C23/08
Filed: 1987-05-07
Abstract: PURPOSE:To manufacture the titled pipe having accurate hole positions and a prominent profile by making holes in parallel with the length direction of a columnar billet and using a composite billet of which the holes are packed with rod material and glass powder. CONSTITUTION:The holes are made in the direction of the length of the columnar billet 1 and packed with the rod material 2 and the glass powder 9 to form the composite billet 3. This billet 3 is heated and inserted into a container 5, hot extrusion is carried out by passing a die 7 by a stem 6 to remove the rod material 2 and the glass from an extruded material 8. When the holes of the composite billet 3 are packed with the rod material 2 and the glass powder 9 and heated to make a hot extrusion, the glass becomes fluid in the composite billet 3 but the fluid glass resists the deforming pressure of the billet to obtain the extruded stock 8 which is uniformly packed with the glass in a rod shape. When the glass is fluid after hot extrusion, both ends of the extruded material 8 are opened to draw out the rod material 2 and make the glass flow out of the holes under pressure.

Title: Level detector of tuning fork type
Inventor: KOMATSU ISAMU
IPC: G01F23/22
Filed: 1977-09-14
Abstract: PURPOSE: To prevent erroneous operations even for the level detection of ultra fine powders by forming a tuning fork into a general Y-shape so that its U-shaped portion is used to establish vibrations and that its I-shaped portion is used to detect the level.  
     CONSTITUTION: A tuning form 6 is formed into a general Y-shape which is composed of a U-shaped portion for vibrations and an I-shaped portion for level detection. The form 6 is vibrated with its intrinsic freqnency, which is converted by a piezoelectric element 2A into electric signals to be amplified by an amplifier 7. If, now, fine powders are brought into contact with the I-shaped portion 6b forming the fork 6 so that this portion is retained, the positive feedback loop is blocked to attenuate the vibrations until they are stopped. If, on the other hand, the restrictions are released, the fork 6 restarts its vibrations.
