Title: Production of grain oriented silicon steel sheet
Inventor: SUGIYAMA MOTOTOMO
IPC: C23F17/00
Filed: 1983-10-22
Abstract: PURPOSE:To produce a grain oriented silicon steel sheet having a low iron loss in the process for producing said steel sheet by subjecting the steel sheet to chemical polishing until the 20 deg. specular surface gloss after chemical polishing attains a specific value. CONSTITUTION:A steel sheet is cold-rolled to the thickness of the final product and is then subjected to decarburization annealing. A separating agent for annealing consisting principally of alumina is further coated thereon and thereafter the steel sheet is subjected to final box annealing to complete secondary recrystallization. After the surface oxide is removed, the steel sheet is subjected to chemical polishing or electrolytic polishing so that the surface of the steel sheet has the 20 deg. specular surface gloss by a method for measuring gloss regulated by JIS Z 8741 ranging 30-240. A coating liquid of tension applying type is thereafter coated on the surface and the steel sheet is heat-treated in a temp. range of 600-850 deg.C. The grain oriented silicon steel sheet from which the coating of the stress applying type does not peel and which has an extremely low iron loss is thus produced.

Filed: 1986-08-25
Abstract: PURPOSE:To read contents of picture elements at a high speed by controlling an output of a vertical scanning signal to a vertical column while a scanning control means scans the picture elements horizontally so as to scan the orthogonal picture elements obliquely in 2-dimension arrangement. CONSTITUTION:A clock signal from a basic clock oscillator 6 is fed to a timing circuit 5 as a solid-state image sensor scanning control means and a horizontal scanning signal HD is applied to a horizontal shift register 3 at a prescribed time. Further, the circuit 5 inputs a vertical scanning signal VD changing at each 3-pulse of the signal HD to a vertical shift register 4. Plural orthogonal picture elements 2 in 2-dimension recorded on an image sensor array 1 are scanned obliquely. Then a photo diode D is turned on at a location where output pulses of the registers 3, 4 meet to turn on a horizontal transistor (TR)h and a vertical (TR)v of the picture elements 2 in the vertical column is turned on by a scanning signal of the register 4 to output a picture element signal at an output terminal P.

Title: Wafer cleaning device
Inventor: NUNOTANI NOBUHITO
IPC: H01L21/304
Filed: 1994-08-23
Abstract: PURPOSE: To inhibit a creeping of a cleaning liquid from the upper & surface, of a wafer to the lower surface of the wafer and to prevent the lower surface of the wafer from being contaminated due to the creeping by a method wherein in a single wafer cleaning of the wafer, gas is blown on the outer peripheral part of the lower surface of the wafer. CONSTITUTION: A wafer 1 is carried by a mount stage 2. Nitrogen gas N2 is blown off on the side of the back of the wafer 1 through a blow-off port formed in the center part of the upper surface of the stage 2 via a hollow rotating axis 3. A cleaning liquid 22 dripped on the upper surface of the wafer 1, which is rotated along with the stage 2, through a nozzle 21 flows in the diametrical direction of the wafer 1 by the centrifugal force of the wafer and collects on the outer periphery of the wafer 1. However, as the gas N2 blows from the rear of the wafer 1 onto the outer periphery of the wafer in the direction from the center of the wafer 1 to the outer periphery of the wafer 1, a creeping of the liquid 22 to the rear of the wafer 1 is inhibited. The liquid 22 is blown off from the outer periphery of the wafer 1 by the centrifugal force of the wafer.  As this result, the rear of the wafer is never made dirty with the cleaning liquid for the wafer itself.

Title: Finder device for single-lens reflex camera
Inventor: YAMAGUCHI TAKAO
IPC: G03B13/26
Filed: 1986-08-28
Abstract: PURPOSE:To reduce the loss of the quantity of light of a finder optical system and to obtain uniform brightness over an entire visual field by forming a half- mirror so that the transmissivity is smaller at a peripheral part than at a center part. CONSTITUTION:The half-mirror 2 is so formed that the transmissivity is high at the center part 2a and lower at the peripheral part 2b than at the center part 2a. Thus, the transmissivity of the peripheral part 2b of the half-mirror 2 is low, namely, the reflectivity is set high, so the brightness of the subject image at the peripheral part which is apt to decrease owing to the influence of the aperture efficiency and cos biquadrate rule can be improved. Thus, the loss of the quantity of light of the finder optical system is reduced to make the brightness uniform over the entire visual field.
