Filed: 1988-04-28
Abstract: PURPOSE:To enable image formation of high picture quality by providing a means which detects the surface potentials of the toner layer of a developing roller and an image carrier selectively, and controlling the AC component of a developing bias and the electrostatic charging quantity of an electrostatic charging device according to the detection result. CONSTITUTION:The detecting means 66 detects the electrostatic charging quantity of toner T' itself which forms a toner layer T' on the surface of the developing roller 56 and a control means supplies to a control signal for a developing bias transformer according to variation in the surface potential of the toner layer T' to adjust the bias voltage of an AC power source 61 automatically. Further, a detector rotating means rotates and displaces the detector 67 of the detecting means 66 to put a detection part 67a opposite to a photosensitive body 2 and detect the surface potential, and when the electrostatic charging quantity decreases and the surface potential becomes smaller than a specific value, the detection result of the detecting means 66 is sent to the control means to control the transformer for the electrostatic charging device. When the electrostatic charging quantity of the toner T of a developing device varies, or when the surface potential of the image carrier varies, this simple constitution easily copes with that and the image formation of high picture quality is performed.

Abstract: PURPOSE: To maintain the arc current at a fixed level without increasing the element to ensure an effective use to the neutral particle accelerator or the like, by providing the arc voltage control loop between the arc electrode and the SCR rectifier.  
     CONSTITUTION: The arc voltage control loop comprising the arc voltage detecting circuit 20, the amplifier 21 and the comparator 21 is provided between the arc electrode 8 which is controlled by the chopper 7 and the SCR rectifier 3.

This error signal controls the rectifier 3 via the gate pulse generator 13. Thus a quick following can be secured to the sudden change of the arc voltage caused when it commutates from the chopper 7 to the electrode 8. Furthermore, the arc current can be changed into the constant current by advancing the phase of the gate pulse to be applied to the rectifier 3.

Title: Device for producing single crystal of compound semiconductor
Inventor: SAKAGUCHI HARUNORI
IPC: C30B15/26
Filed: 1983-06-13
Abstract: PURPOSE:To detect exactly the shape of a pulled up single crystal and the position of a melt surface and to obtain the crystal having high quality with high performance by irradiating an X-ray to the single crystal formed by a pull-up method and the neighborhood of the melt surface, moving the irradiating position and detecting the presence or absence of the diffracted beam. CONSTITUTION:The X-ray irradiated from a movable X-ray source 2 alongside a furnace 1 for pulling up a single crystal passes through the outside wall of the furnace body 1, a heater 7 and a crucible 6 and irradiates a pulled up single crystal 4 and the neighborhood of a melt surface 5. The single crystal of a compd. semiconductor is generally pulled up by determining the pull-up face to, for example, the direction <100> and therefore the face regulated by said direction appears on the side face of the crystal 4. If the X-ray having a wavelength lambda is irradiated to such single crystal from the side thereof, a diffracted beam is generated in the position deviated by an angle theta relative with the direction where the X-ray is irradiated. Since such generation occurs in the crystal face appearing on the side face of the single crystal, the irradiating position of the X-ray is moved and the presence or absence of the diffracted beam is detected by an X-ray detecting part 3 turnable around the furnace 1, by which the outside shape of the crystal 4 and the position of the surface 5 are known.
