Filed: 1988-07-28
Abstract: PURPOSE:To increase the throughput by selectively exposing the periphery of a wafer to rays with an exposure part having an arc of a radius equal to the length obtained by subtracting the depth of the part to be selectively exposed from the radius of the wafer. CONSTITUTION:For example, an exposure part is shaped into the form of a square of 5mm sides and a side on the side of the center of a wafer is shaped into an arc of 47mm radius by selectively exposing the wafer to rays to 3mm depth from the peripheral surface. Forming the exposure part of the abovementioned shape makes the length of the part exposed to UV rays at a depth of 3mm from the peripheral surface of the wafer equal to that of the center of the exposure part. To be precise, the decrease of the radius is equal to the increase of the effective length. Sensitive resist is sufficiently exposured to rays, and the inclination of the cross section thereof is steep to shorten the inclined part.

Abstract: PURPOSE:To produce extremely high-quality In by electrolytically refining crude In as a consumable anode in a diaphragm cell with an aq. soln. of InClx as the electrolyte, heating, and melting the In deposited on a cathode along with a chlorinating agent. CONSTITUTION:An aq. soln. contg. 100-300g/l indium chloride adjusted to 0.5-2.0pH is used as the electrolyte, and crude In contg. <10ppm Cd and <1ppm Tl as a consumable anode is electrolyzed at 0.5-2A/dm<2> cathode current density in the diaphragm cell using natural fibers such as cotton or synthetic fibers such as PE as the diaphragm to deposit high-purity In on the cathode. The electrolyte discharged from the anode chamber during the electrolytic refining is filtered to remove suspended slime, successively brough into contact with an anion-exchange resin to remove Ag, Bi, and other impurities, then returned to the cathode chamber, and electrolyzed. The In deposited on the cathode is released from the cathode, heated, and melted along with a chloride such as ammonium chloride to remove the remaining impurities in the In as the chloride. Consequently, In having >=99.9999% purity can be produced.

Title: High frequency amplifier
Inventor: KINDAICHI YOUZOU
IPC: H03G3/00
Filed: 1990-07-18
Abstract: PURPOSE:To prevent the degradation of efficiency even in the case of a low RF output by adjusting a plate voltage in accordance with the output of a high frequency amplifier to approximately equalize the amplitude of the plate voltage to a DC plate voltage. CONSTITUTION:When a high frequency (RF) output is set by an output set part 11, the output of an automatic gain control(AGC) circuit 5 is prescribed by a differential amplifier 13, and a high frequency amplifying part 4 is driven by the output, and the plate voltage amplitude of the high frequency amplifying part 4 is reduced when the output set value is small. In accordance with this reduction, the ignition angle is controlled in a thyristor line control part 10 by the output gate control signal of a differential amplifier 14 to reduce a DC voltage EDC as the output of a rectifying circuit 3. Since this DC voltage EDC is used as the plate voltage of the high frequency amplifying part 4, the DC voltage EDC is reduced when the RF output amplitude is reduced. Thus, the amplitude of the DC plate voltage is approximately equalized to the DC plate voltage, and the use rate of the plate voltage is reduced, and the degradation of efficiency is prevented regardless of the low RF output.
