Title: System for verifying connection of line in line editing device
Inventor: TANAKA MASASHI
Filed: 1987-12-08
Abstract: PURPOSE:To prevent the scale of a circuit from being increased and to shorten a time to verify the connection of a line by confirming the fact that the output line is connected to a desired input line by an ID code taken out from each output line at the interface part on the output side. CONSTITUTION:An input side interface part 2 performs the staffsynchronization of plural asynchronous input lines, and also, inserts the ID code representing each proper identification number to the surplus bit of each input line, and inputs it to a line editing device 1. Also, an output side interface part 3 performs the separation of the staff-synchronization of the output of each output line in the line editing device 1, and reproduces and outputs each original signal, and also, extracts an inserted ID code. Therefore, it is possible to judge to which line each output line is connected immediately by the identification number of the input line being shown as the ID code. In such a way, the scale of the circuit can be prevented from being increased and the time to verify the connection of the line can be shortened.

Title: Large-sized grating
Inventor: TODA EIZO
IPC: E03F5/06
Filed: 1997-11-12
Abstract: PROBLEM TO BE SOLVED: To almost uniformly impart a nonslip function to the whole road face of a grating by arranging the nearest auxiliary members to the main members in a plurality of auxiliary members on which a nonslip rugged face is formed on the upper end face, so as to get into contact with the main members. SOLUTION: A plurality of auxiliary members 4 in which a nonslip rugged face 7 is formed on the upper end face by a continuous hot rolling during a raw material, are arranged parallelly with main members 1 between adjacent main members 1, 1. In this time, the auxiliary members 4a, 4a in the closest positions to the main members 1 are arranged to get into contact with the main members 1. Accordingly, even if the upper end face 1a of the main member 1 is left without the rugged face treatment, a nonslip function which the upper end face of the main members 1 lacks, can be supplemented by the rugged face 7 of the upper end face of auxiliary members 4a, 4a having a low production cost, brought into contact therewith.  In this way, a nonslip function can be almost uniformly imparted to the whole road face or the grating in cooperation with the rugged face of the upper end face of other auxiliary members.

Title: Wafer support unit in semiconductor manufacturing apparatus
Inventor: TAKAGI YOJI
IPC: H01L21/683
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To provide a wafer support unit in a semiconductor manufacturing apparatus, having a lift mechanism capable of preventing a flaw on the reverse surface of a wafer and the position shift of the wafer. SOLUTION: A wafer support unit 14 has a wafer support body 22, whose upper surface has a support area 26 for supporting a wafer W, and a plurality of lift members 36 each of which has an upper surface which extends inclined downwardly toward the inside of the support area 26 of the wafer support body 22 from outside the support area 26, and each of which can move vertically between a position lower than the upper surface of the wafer support body 22 and a position higher than the upper surface thereof. Because the position where the lift member is mounted and the upper surface thereof inclined, the lift member 36 does not contact with the reverse surface of the wafer W but makes contact with only the outer peripheral portion of the wafer W. Accordingly, this can prevent the flaws in the reverse surface of the wafer W.  Since the nearer to the outside the position of the upper surface of the lift member 36 is, the higher it becomes, so that the position shift of the wafer W in the horizontal direction can be prevented.

Abstract: PURPOSE:To obtain a display having a bright screen and high display quality by disposing a transparent substrate formed with microlenses and a thin type transparent substrate in such a manner that these substrates are adjacent to each other on the microlens surface sides of the transparent substrates. CONSTITUTION:Thin-film transistors 8 and transparent electrodes 7 consisting of ITO constituting picture elements are formed on the substrate substrate 6. The transparent substrates 2, 6 are fixed by an adhesive and a liquid crystal material 9 is injected and packed into the spacing therebetween. A convex lens array 3 is so determined in the radius of curvature as to focus at the positions of the transparent electrodes 4 constituting the picture elements. Incident light 10 past the array 3 is condensed to the electrodes which are apertures and thereafter, the light transmits the electrodes 7 and the substrate 6. Almost all the light passes the electrodes 4 without being shielded by shielding bodies 5 and improves the screen brightness when the light 10 is made incident in parallel in the case of a liquid crystal valve contg. this optical element. The opening rate of the picture element is, therefore, substantially increased and the display having the bright screen and the high display quality is obtd.
