Title: Light amount controlling device and image forming device
Inventor: NAKAMORI TOMOHIRO
IPC: H04N1/113
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To equalize the light amounts at the positions to be exposed of respective light beams with each other and make it possible to form images with no uneven image by a method wherein output currents in response to the light amounts of the light beams sent from respective light emitting parts are converted to voltages so as to control driving currents in order to coincide the voltages with the aimed light amounts set at the respective light emitting parts. SOLUTION: A current Ipd in response to the light amount is outputted by means of the light emitting parts 2 and 3 and the pin photo-detector 4 of a multibeam semiconductor laser 1 and current-to-voltage converted by a resistor 5 and transmitted through a voltage follower circuit COV to a CPU 10 in the form of a light amount detection signal PDIN. Further, at the A/D port 11 of the CPU 10, the aimed voltage of the signal PDIN at the controlling of light amount is produced by means of resistors 12 and 13 and variable resistors 14 and 15 in a laser unit. The CPU 10 adjusts the respective outputs at the D/A port 16 so as to control laser currents in order to coincide the signal PDIN with the aimed voltages Vpd1 and Vpd2 for controlling the light amount on a photosensitive drum surface after the laser light is throttled to the desired value.

Title: Semiconductor device
Inventor: HAGIO MASAHIRO
IPC: H01L29/78
Filed: 1982-12-01
Abstract: PURPOSE:To make surge resistance highly excellent, by connecting a connected body, wherein two P-N junctions having different junction areas are connected in series in the reverse directions to each other, to a Schottky junction or an MOS structure in parallel. CONSTITUTION:A connected body, wherein two P-N junction having different junction areas are connected in series in the reverse directions to each other, is connected to a Schottky junction or an MOS structure. For example, P-N junctions, which protect the Schottky junction of a gate, are connected to a GaAs MESFET. In this case, the junction area of the P-N junction J1, which is directed in the same direction as that of the Schottky junction of the gate is made different from the junction area of the P-N junction J2, which has the reverse direction to the Schottky junction. When the saturated value Is1 of the breakdown current in the reverse direction of the junction J1 is made sufficiently large in order to protect the FET, junction capacity C1 is increased. At this time, the junction area of the junction J2 is made small and capacity C2 is made small. Therefore, the P-N junctions comprising the junctions J1 and J2 hardly deteriorate the FR characteristics of the FET.

Abstract: PURPOSE:To enhance the dimensional precision of direct operated machine elements by forming a first and second normal gash on the outer surface of a spline shaft and the inner surface of a spline nut, respectively, and parallel to respective axes, and interposing a cross roller bearing between the first and second opposite normal gashes. CONSTITUTION:A spline shaft 1 has three normal gashes 102 provided on the surface of a guide portion 101 and along the axis thereof and the two planes 103 of each gash 102 make an angle of 90 deg., and a spline nut 2 has three normal gashes 202 provided on the inner surface thereof and the two planes 203 of each gash 202 make an angle of 90 deg.. A cross roller bearing has rollers which are themselves freely flexuously connected into a caterpillar ring by connectors, and when the spline nut 2 makes rectilinear reciprocating motion along the spline nut l, each of the rollers of the bearing makes rolling contact with one of the two planes of each normal gash 102 and one of the two planes of each normal gash 202 simultaneously. The spline shaft and nut are therefore resistant to flawing even with foreign matters entering therein and so accuracies can be maintained over a long time.

Abstract: PURPOSE:To carry out a suitable discharge to cause the carrier to return to a normal heat carrying state even when a non-compressive gas is accumulated by providing an electromagnetic valve at the upper part of a tank whose heat radiating side is hermetically closed tank, detecting the temperature or the pressure on a block whose heating side is hermetically closed so as to control the opening and closing of the electromagnetic valve. CONSTITUTION:When a working liquid 20 within a heat exchanger 7 is heated by the operation of a heat source 6 and begins to evaporate, the working liquid 20 is formed into air bubbles, which are subjected to gas-liquid separation by a gas-liquid separator 8. Steam then reaches a heat radiating part 13. The working liquid 20 the condensation heat of which the been robbed by the heat radiating part and which has been liquefied reaches a heat radiating side tank 18. When a non-compressive gas is accumulated within an enclosed system, the temperature and the pressure at the time of the heating operation rises up as compared with the normal time. Therefore, the temperature and the pressure are detected by detecting means 21, and an electromagnetic valve 19 is opened by the operation of a controller 22. Then, when the non-condensed gas collected at the upper part of the tank 18 whose heat radiating side is hermetically closed is discharged and the electromagnetic valve 19 is opened, the device is returned to the normal state.
