Title: Photomask blank and phase shift mask
Inventor: KONISHI TOSHIO
IPC: G03F1/80
Filed: 1991-06-05
Abstract: PURPOSE:To enable stable phase shift mask patterns to be formed with high accuracy by using a photomask blank constituted by successively providing a transparent conductive film, an etching stopper layer and phase shift layers on a transparent substrate. CONSTITUTION:The photomask blank is constituted by successively laminating the transparent conductive film 2, the etching stopper layer 3 and the phase shift layers 4 on the transparent substrate 1. A resist layer 5 is provided on the photomask blank and prescribed patterns are plotted thereon by electron beam exposing 6. This layer is developed to form resist patterns 5'. The phase shift layer 4 is then patterned 4' by drying etching with the resist patterns 5' as a mask. The resist patterns 5' are finally removed, by which the phase shift mask is completed. The generation of charge-up at the time of plotting by an electron beam is prevented by the presence of the transparent conductive layer 2 in such a manner. Since there is the etching stopper layer 3, the control of the etching quantity is facilitated.

Title: Detection for core bar
Inventor: NOGAKI TADASHI
IPC: G01S17/04
Filed: 1984-07-31
Abstract: PURPOSE:To detect surely whether a core bar is present or not by arranging a light projecting optical fiber and a light receiving optical fiber adjacently to each other and receiving the light, which is projected from the light projecting optical fiber and is reflected on a work or the like, by a light receiving optical fiber. CONSTITUTION:A device consists of a light projecting optical fiber 2, a light receiving optical fiber 3, a core bar R, work W a detector 5, an alarm buzzer 6, etc. The radiated light is reflected on a core bar R, a cushion rubber C, etc., and a part of this reflected light is made incident on the light receiving optical fiber 3. This reflected light is made incident on the detector 5 and is converted photoelectrically in accordance with the incident luminous flux; and since the output level for the presence of the core bar R is preliminarily set to the detector 5, the alarm buzzer 6 is sounded by comparing discrimination if a level lower than this level is inputted, that is, the core bar R is absent. Thus, the presence/absence of the core bar R is detected.

Abstract: PURPOSE:To securely hold a bearing portion in a socket without any looseness in a joint by constructing the joint in such a manner that a step portion the opening end side of which is smaller is formed on the circumferential wall of the opening of the socket and a plug is engaged with the step portion at the expanding end of its cylindrical portion to hold the socket. CONSTITUTION:Since the expanding end 23 of the cylindrical portion 21 of a plug 10 abuts to and engaged with the step portion 24 of the opening 2 of a socket 1, disengagement of the plug 19 in A-direction is prevented and a bearing 12 and the ball portion 9 of a pillow ball 6 are held or blocked in the socket 1 without any possibility of looseness in A, B directions or disengagement in the A-direction. In the case of this plug 19, the movement of a plug 18 in A direction is accompanied with the movement in C direction, of the end 23 of the cylindrical portion 21 so the movement in A direction is hard to occur and the looseness and the disengagement of the bearing 12 and the pillow ball 6 may hardly occur.

Title: Electron shower device for ion implantation device
Inventor: FUJII HARUHISA
IPC: H01L21/265
Filed: 1991-07-02
Abstract: PURPOSE:To eliminate effect of heat or contamination from a filament to a wafer being implanted with ions, and to neutralize the charge on the wafer. CONSTITUTION:Flat electrodes 11 are mounted on the inside of a chamber 8 in parallel to one another. High frequency voltage is applied from a high frequency power source 12 to the electrode 11, and high frequency discharging (multipactor discharging) occurs in high vacuum, and an electron cloud is formed thereby. The electron is applied to a wafer 7 that is positively charged. Since a heat filament is not used, problems of heating and contamination on the wafer are eliminated, and since a low energy electron is applied, negative charging distribution is not generated on the wafer, and a semiconductor device of high reliability can thus be manufactured.

Title: Dc loop forming circuit
Inventor: UNO KOJI
IPC: H04L25/02
Filed: 1985-07-22
Abstract: PURPOSE:To reduce a leakage current by inputting a digital signal between the gate and source of the 1st transistor (TR), smoothing an output obtained between the drain and source of the 1st TR and inputting the result to the 2nd TR forming a DC loop. CONSTITUTION:A digital signal inputted between input terminals t1 and t2 is fed between the gate and source of a FET Q2. Since the polarity of the voltage fed from a transmitter in standby at an output terminal t3 is positive and that at an output terminal t4 is negative, the current detected according to the cut-off characteristic of the FET Q2 flows to resistance elements R4, R5 and the current flowing to the resistance element R4 charges a capacitor C4. A DC voltage appears across the capacitor C4 by charging, the detected current is smoothed by a smoothing circuit 5 and its smoothing output is fed between the gate and source of a FET Q3, which is turned on to form a current loop. Thus, the leakage current is reduced.

Title: Display device
Inventor: WASHIMI SATOSHI
IPC: G09G3/16
Filed: 1985-07-22
Abstract: PURPOSE:To strain the boundary surface of an optical waveguide directly and varies an angle of reflection, and to obtain high brightness and high contrast by forming the optical waveguide of an elastic member and providing an external strain inducing means which applies external stress to the intermediate part of the optical waveguide and strains the optical waveguide. CONSTITUTION:When a strain generating device 9 is put in operation, pressure or tensile force is generated to strain the optical waveguide 6, so that the boundary surface between the optical waveguide 6 and its clad layer 8 is strained. When rays of light 2 propagated in the optical waveguide 6 by total reflection reache the part strained by the stress generating device 9, its angle of reflection varies and the light can not be propagated in the optical waveguide 6, so that the rays of light passe through a clad layer 7 from the optical waveguide 6 and is projected as leak light 2'. Thus, the boundary surface between the optical waveguide 6 and clad layer 8 is strained directly to vary the angle of reflection, so the direction of the leak light is controlled accurately and stably.

Abstract: PURPOSE:To avoid trouble at the time of folding by providing constitution such as flexing a predetermined fold of continuous paper on the halfway of its conveyance to detect the direction of flexing this fold so that the fold of the accumulated continuous paper can be always aligned folded. CONSTITUTION:When the direction of a folding a perforation is detected, restricting means 11, 12 are once stopped when the one predetermined perforation reaches between a pair of detecting sensors 13, 14. Next, the restricting means 11 in the upstream of a conveying route 9 is left as stopped to rotate only the other restricting means 12 in an opposite direction a little, and continuous paper 1 is pulled back a little from the conveying route 9. Then, by loosening the continuous paper 1 between the restricting means 11, 12 the perforation is flexed press-raised in a direction of providing a folding habit. As a result, in the case that the perforation is a mountain fold, light receiving between the sensors 13, 14 is disturbed by a flexing part 15 to detect the mountain fold. On the other hand, in the case of follow folding, light receiving is not disturbed by a flexing part 16 to detect the hollow folding.
