Abstract: PURPOSE:To form a film of a hardly releasable material on the inner wall of a vacuum vessel and to reduce the frequency of periodical cleaning by sputtering a material other than a target with a cathode for forming a film of a material to be treated without exposing the inside of the vessel to atmosphereic pressure. CONSTITUTION:A substrate 15 (a target of Al, etc., for forming a film on the inner wall of a vacuum vessel) on which a material to be treated is not placed is raised by a driving mechanism 10, brought into contact with the surface of the target 6 and held, airtightness is kept between the target 6 and a vacuum vessel 1 by a flat plate part 15a, a cylindrical part 15b and an airtight member 17, and the holder 15 is kept away from an anode 5. Under these conditions, a high voltage is impressed on a backing plate 2 (cathode) to ionize Ag by an electric discharge, and plasma is produced. Sputtering is conducted from the lower surface of the holder 15 to deposit a film on the inner wall of the vessel 1. Consequently, the target is not contaminated, and the hardly releasable film is formed on the inner wall of the vessel 1.

Title: Controller for quantity of passing light
Inventor: AMANO NAOYUKI
IPC: G02F1/01
Filed: 1985-03-20
Abstract: PURPOSE:To hold the quantity of passing quantity at an optional constant value regardless of incident light which varies abruptly by varying the quantity of attenuation of a passing light attenuating means according to the quantity of passing light. CONSTITUTION:The incident light 4 which varies in quantity with light is attenuated by passing through the passing light attenuating means 1 which varies in the quantity of passing attenuation to obtain passing light 5. A photoelectric converting means 2 converts the quantity of the passing light 5 into an electric light quantity signal 6, which is sent out to an attenuation quantity control means 3. The control means 3 compares the light quantity signal 6 with a reference value input 7 and sends out an attenuation quantity control signal 8 to the attenuating means 1 according to an increase in the light quantity signal 6 when the light quantity signal 6 exceeds the reference value 7, thereby increasing the quantity of passing attenuation. Thus, the incident light 4 is attenuated by the passing attenuating means 1 according to the quantity of light to obtain the passing light 5.

Filed: 1980-04-30
Abstract: PURPOSE:To protect a switching transistor for a load by blowing a fuse by increasing a load current by holding the base current of the transistor nearly constant even when an overcurrent flows through a circuit. CONSTITUTION:When load signal S is supplied as an on-signal to turn on transistor TR1, the voltage across resistance R1 is as shown by expression I where the collector-emitter voltage of TR1 is VCE1. If the current of TR2 flowing through resistance R3 is I and the base-emitter voltage is VBE2, current I flows to equalize the sum of the voltage drop across resistance R3 with current I and base-emitter voltage VBE2 OF TR2 to expression 1, and resistances R1-R4 are set to establish equation 2. If an overcurrent flows, the collector current of TR3 can be increased with the base current of TR3 held nearly constant. Consequently, fuse H is blown early to protect TR3.
