Abstract: PURPOSE:To shorten a measuring time capable of obtaining a highly accurate measuring result by one scanning and to improve an S/N ratio, by controlling the amplification degree of a variable amplifier by a comparator and a counter. CONSTITUTION:A current is allowed to flow to a laser diode (LD) 1 whose position is mixed to emit definite beam output and the intensity distribution of laser beam spreading to the space at the definite distance from the beam emitting point of LD 1 is scanned so that a photodetector 2 having a minute beam receiving diameter draws a circle at a definite distance with respect to the light emitting point and the beam receiving level of the photodetector 2 to a moving angle is measured as beam emitting intensity distribution. Herein, the output current of the photodetector 2 is converted to voltage by a current- voltage converter 3 and amplified by a variable amplifier 4 but the output thereof is compared with reference voltage by a comparator 5. The comparing output is counted by a counter 6 and the count output controls the amplification degree of the amplifier 4. Therefore, dealing with various input levels is enabled and a highly accurate measuring result can be obtained by one scanning.

IPC: C23C2/00
Filed: 1978-06-30
Abstract: PURPOSE:To produce one-side plated steel plates by disposing a positive electrode near the plating surface of the steel plate and a negative electrode on the non-plating surface side, letting hydrocarbon gas burn imperfectly while applying voltage between both electrodes to let soot deposit on the non-plating surface and introducing the steel plate into a hot dipping bath. CONSTITUTION:A steel hoop 6 having been cold rolled is introduced into an oxidizing furnace 7, where deposits such as rolling oils are burnt away. Next, it is put into a reducing furnace 8 of the atmosphere of H2; 10%, N2; 90% to reduce the oxide film on the surfaces of the steel hoop 6. The steel plate 6 is then put into a masking chamber 9, where a DC voltage of 500V or higher is applied between the positive electrode 2 disposed by leaving a spacing of 1 to 50 mm on one side and the burner 3 being a negative electrode for causing acetylene gas or the like to burn imperfectly. Soot produced through incomplete combustion is evenly deposited on the steel hoop surface on the negative electrode side. This steel hoop is then introduced into a hot dipping bath 11 such as of Zn. The surface having been deposited with soot is not plated, thus the one-side plated steel hoop is readily obtained.

Filed: 1989-03-30
Abstract: PURPOSE:To form a base and a collector in a self-aligned manner and to make this transistor small-sized by a method wherein a polyimide resin is applied, its surface is flattened and, after that, the whole surface is etched. CONSTITUTION:When a base electrode 7 is formed on a metal layer of a two- layer structure composed of the metal layer and a gold-germanium layer, an electrode layer on a collector-electrode formation region is left as it is; a wafer is coated with a polyimide resin 12 and its surface is flattened and heat-treated; the polyimide resin is hardened. After that, a large opening (h) is formed on the collector-electrode formation region; a photoresist and the polyimide resin 12 are removed simultaneously; an ion milling method is continued. Accordingly, an etch rate of gold is about three times as fast as that of the polyimide resin 12; as a result, the metal layer for the base electrode 7 on the collector-electrode formation region 4 can be removed completely in a state that the polyimide resin is left sufficiently. Thereby, since an external base region and a collector region are formed in a self-aligned manner, an area occupied by an element can be made small.
