Title: Polarizing beam splitter
Inventor: SATOU KATSUHARU
IPC: G02B5/30
Filed: 1979-01-11
Abstract: PURPOSE: To reduce working face, polishing face and coating face respectively by coating multilayer films on the surface of a parallel plane plate made by optical material which has the specified refractive index and is superior in transmission characteristic of light thereby forming the polarizing face.  
     CONSTITUTION: This is the polarizing beam splitter which allows the transmission of the rays radiated from a light source and meanwhile separates its reflected light and its polarizing face 5 is formed by coating multilayer films of magnesium fluoride, zirconium oxide or the like on one surface of a parallel plane plate 4 made by optical material such as glass, crystal or other material which has the specified refractive index and is superior in transmission characteristic of light. It is disposed with an inclination at the specified angle (e.g., 45°) to the optical axis 6 from the light source, on the light source side of a wavelength plate 3. Such constitution reduces the number of steps, makes working easy and enables the increase in accuracy.

Title: Manufacture of square welded steel pipe
Inventor: ONO EIJI
IPC: B23K9/025
Filed: 1980-01-14
Abstract: PURPOSE: To manufacture easily a square steel pipe with a large ratio of the plate thickness to the side length by forming a square shape under a relatively small pressure, by roughly forming the pipe in a square shape as it is in an open section state while a fin pass roll is passed.  
     CONSTITUTION: A material bent in an arc shape by a breakdown roll is roughly formed by a fin pass roll in the next squaring fin pass process. Namely, fed material 6 whose section is in the arc shape is pressed against lower roll 3 by fin roll 1B and pushed from left and right by left and right rolls 2 and 4 while pushed inward by flange roll 1A; both edges 7 are brought into contact with both sides of roll 1B and deform within the caliber to form a shape along the roll curved surface easily. At the final stage of the fin pass roll, the material having the welding seam formed in an oval open-shaped roughly-square section shape has the seam positioned properly by a squeeze roll and is welded, so that seam S will have a section-squared shape in the center of the top surface. In a reforming process, each surface is flattened by a turks-head roll to reform corner parts at right angles.

Abstract: PURPOSE:To improve the ohmic property of a back surface electrode in a semiconductor device by bonding a thin Si plate on the back surface of a wafer with liquid Si oxide containing an impurity as an adhesive and then forming an element on the front surface of the wafer. CONSTITUTION:A thin Si film 13 having approx. 150upsilonm of thickness is bonded to the back surface of an Si wafer 11 with a liquidin which SiO2 powder containing P2O5 is dissolved in an organic material as an adhesive, and is heated to  form a PSG layer 12a in the boundary. An element is formed by an ordinary  method on the front surface side of the wafer. Then, the front surface of the wafer is protected with acid resistant wax. The wafer is then dipped in an  etchant to remove the films 13 and 12a. An electrode (collector electrode) is  formed on the exposed back surface of the wafer. In this manner, since a high  impurity density layer is formed of the back surface by the heat treatment at  the time of forming a base and an emitter, its ohmic property can be improved.

Title: Metal deposition method
Inventor: KAKIUCHI TAKAO
IPC: H01L21/28
Filed: 1988-01-08
Abstract: PURPOSE:To enable an interconnecting metal to be deposited very desirably, by forming a thin semiconductor film on the side and bottom walls of a contact hole immediately after cleaning the inner surface of the contact hole, and then depositing the metal within the contact hole. CONSTITUTION:Immediately after the inner surface of a contact hole 3 is cleaned to remove a spontaneously oxidized film 4, the inner surface of the contact hole 3 is coated with a thin Si film 8 within the same reaction chamber or a second reaction chamber connected to the first one through a vacuum chamber. After the interface between the Si film 8 and an Si substrate 1 is kept without any oxide film, a metal 9 is selectively deposited within the contact hole 3, free from local penetration of W. Since the surface of the Si substrate 1 within the contact hole 3 is coated with a semiconductor or metal film without any spontaneously oxidized film thereon and is preserved in such state, there is no possibility, in the deposition of the metal, of causing local penetration of W by virtue of an effect of the spontaneously oxidized film. Accordingly, the deposition of the metal can be performed desirably.

Filed: 1982-01-14
Abstract: PURPOSE:To make electrifying width variable, by dividing an electrifying brush placed in the axial direction of a rotating photosensitive drum, and applying the voltage selectively, in a device which makes the electrifying brush contact with the photosensitive body and electrifies it by applying the voltage. CONSTITUTION:An electrifying brush 2 which is in contact with a photosensitive drum 1 is constituted by placing conductive plates 8''1-8''7 like zigzag on a substrate 8'', and embedding conductive brushes 8'1-8'7. The electrifying width can be varied by applying the voltage selectively to conductive plates 8'''1-8'''7. Also, each conductive plate 8'''1-8'''7 is placed separately so as to be insulated electrically, but since they are placed like zigzag alternately in 2 rows, electrification is executed continuously. Because of brush electrification, the electrifying width can be selected efficiently as compared with that which is electrified  to specified width, and thereafter, is destaticized to prescribed width by an erasing lamp. Also, supply voltage required for electrification is low, and switching is executed easily.

Abstract: PROBLEM TO BE SOLVED: To provide a video signal having no black relief even in a four-times speed shooting mode. SOLUTION: An offset value set by a CPU 44 is added to an output from an A/D converter 46 by an adder circuit 48. Based on an OB level for eight picture elements at the rear edge of each line signal in an ordinary speed shooting mode (1st shooting mode) and based on an OB level for two picture elements at the front edge of each line signal in the four-times speed shooting mode (2nd shooting mode), a clamp level calculation circuit 50 calculates the clamp level of the 1st or 2nd shooting mode. Clamping is performed by subtracting the clamp level from the output of the adder circuit 48 while using a 1st subtraction circuit 82. The output of the 1st subtraction circuit 82 is clipped to zero by a zero clip circuit 84 and passed through a low-pass filter 86 and further, the same offset value is subtracted by a 2nd subtraction circuit 88.
