Title: Image forming device
Inventor: TAMAGAWA YOUICHI
IPC: G03G21/00
Filed: 1983-11-17
Abstract: PURPOSE:To prevent generation of defective pictures and to extend the use life of an image carrier by stopping application of a bias voltage to a cleaning brush by a bias voltage applying means when rotation of the cleaning brush and the image carrier is stopped. CONSTITUTION:Electric charge on a photosensitive face 10 of a photosensitive drum 9 which is swept of a remaining toner by a cleaning device is removed by an eraser to prepare for the next copying process. Since the voltage is reduced rapidly in case of the end of the copying operation also, bias power sources 6 and 8 are turned off at the timing opposite to that for rotation start, namely, after rotation of the photosensitive drum 9 is stopped and rotation of a conductive brush 5 and a recovering roll 7 is stopped. In this manner, bias power sources 6 and 8 are turned off after rotation of the photosensitive drum 9, the conductive brush 5, and the recovering roll 7 is stopped. Thus, the excessive current at the instant of turning-off of bias power sources 6 and 8 has no influence upon the photosensitive face of the photosensitive drum 9 and a fur body 11 of the conductive brush 5. Then, the use life of the image carrier is extended, and generation of defective pictures is prevented.

Title: Semiconductor producing system
Inventor: MUTA MARI
IPC: H01L21/68
Filed: 1992-08-13
Abstract: PURPOSE:To enhance machining accuracy by making a recess in the center of a chuck and bringing a wafer into contact with the wafer mounting face on the periphery of the chuck thereby heating only the peripheral part of the wafer. CONSTITUTION:A recess 13 is made at the center on the top surface of a chuck 11 leaving the wafer mounting face 12 on the periphery thereof. When a wafer applied with resist is mounted on the chuck 11, heat is transmitted from the chuck 11 to the wafer only through the wafer mounting face 12 where the chuck 11 abuts on the wafer. Since heat does not transmit directly from the recess 13, central part of the wafer corresponding to the recess 13 is not heated or hardly susceptible to heating. Consequently, machining accuracy is enhanced and fluctuation is suppressed in the finish of pattern. Introduction of chill air into the recess prevents heating at the center of wafer more positively.

Abstract: PURPOSE:To change an optical output linearly with respect to the change in driving current by storing the value of the driving current corresponding. to the output light of a semiconductor laser, inputting the contents into a digital/ analog converter, and driving the semiconductor laser. CONSTITUTION:The driving current of a semiconductor laser and the value of the driving current, which is obtained by correcting the characteristic of the optical output into the straight line, are stored in a memory M. When address signals A0-A15 for specifying the optical output of a semiconductor laser LD are inputted into the memory M, the current value stored into the memory M is read out. The digital signal corresponding to the current value is inputted into a D/A converter DAC. Then, digital/analog conversion is performed. The analog voltage is inputted into an operation amplifier OPA, and a transistor Q is turned ON. A driving current flows into the semiconductor laser LD from a positive electrode +Vcc of a control power supply. Then a voltage is generated across both terminals of a resistor R3 and inputted into the negative terminal of the operation amplifier OPA. The optical output from the semiconductor laser LD can be changed without the effect of the nonlinear part.

Title: Self timing qualification giving channel
Inventor: DONARUDO TEII WAIRU
IPC: G11B20/10
Filed: 1990-08-18
Abstract: PURPOSE: To correctly detect the prescribed pulse by providing a hysteresis comparator and a timing comparator and performing the qualification processing of a signal at immediately before a true peak in a disk reading input signal by this timing comparator. CONSTITUTION: The hysteresis comparator 502 receives a differential output signal from a differential filter 506 and supplies an output signal to the D input lead of a D flip flop 552. The timing comparator 550 detects a true peak of the input signal by comparing the output signal of the amplifier 504 with the input signal of a qualification channel 599. The D flip flop 552 changes its state only at an intersection 'X' corresponding to a time immediately before a time when a channel signal reaches the peak. A noise or an erroneous peak which does not generate the intersection X does not generate a change at the D input lead of a flip flop 553, and thus, an output signal is not generated.
