Title: Surface inspecting device
Inventor: FUKAZAWA CHIAKI
IPC: G01N21/89
Filed: 1988-05-25
Abstract: PURPOSE:To enable evenly accurate detection of the overall width of an object to be inspected without requiring a large-diameter lens, by providing a bundle fiber which has a long-sized light receiving section along the scanning of a laser beam to pick up a reflected laser beam from the object to be inspected. CONSTITUTION:A laser scanner 11 scans the surface of an object 12 to be inspected by a laser beam along the width thereof and reflected laser beam from the object 12 is picked up into a bundle fiber 13. The fiber 13 has a long- sized light receiving section 131 along the scanning of the laser beam and picks up light scattered at a specified cycle at any position across the full width with respect to the laser beam scanning over the surface of the object 12 while light with the same angle as that of the scattered light picked up can be emitted. Thus, a change in a diffraction pattern caused by the existence of a defect in the surface of the object 12 can be created on the same conditions for the full width of the object 12 thereby enabling evenly accurate inspection of a defect across the full width of the object to be inspected.

Title: Production of glass
Inventor: AOKI MIKIO
IPC: C03B37/016
Filed: 1986-06-02
Abstract: PURPOSE:To efficiently carry out the addition and ultrasonic dispersion of fine powder and to enhance the productivity by cooling hydrolyzed glass sol once, adding the fine powder to the sol and producing glass. CONSTITUTION:Glass is produced in a sol preparing stage and a gelling stage. When fine powder is added to hydrolyzed sol in the sol preparing stage, the sol is cooled once to <=40 deg.C and the fine powder is added to the sol. Since the hydrolyzed sol is cooled once, the polymn. of M-OH is inhibited, the viscosity of the sol is kept low and the coagulation of the fine powder is inhibited. Accordingly, the time required to add and disperse the fine powder is shortened and glass can be produced in large quantities with high productivity.

Title: Semiconductor device
Inventor: MUROYA TERUO
IPC: H01L23/495
Filed: 1982-07-22
Abstract: PURPOSE:To perform ground connection of stable characteristic without the exfoliation of chips by a method wherein a ground pin lead whose top end is flat is extended to the chip containing part of a ceramic package, and then a semicondutor chip is fixed to the top end. CONSTITUTION:The leads 3 are so arranged that the top ends are extended from an outer frame 6 and gathered at the center. Of these leads, the top end of the lead 13 serving as a ground pin is particularly extended and flattened, then fitted into the bottom of a chip containing recess at the center of the ceramic package 2, and the semiconductor chip 1 is fixed to the top end. Since the entire body of the chip back surface is connected directly to the ground pin, electric characteristics are stabilized. Further, the chip containing cavity is covered with the top end of the ground pin, therefore, the coating of Au paste for adhering purpose is unnecessitated.

Title: Camera tube
Inventor: TAKASAKI YUKIO
IPC: H01J31/38
Filed: 1986-06-04
Abstract: PURPOSE:To enable even a compact camera tube to have a high resolution so as to make a television camera compact, by combining a photoconductive film of decreased thickness and increased storage capacity with an electron gun whose electron beam defining aperture is made small to reduce the diameter of a scanning electron beam. CONSTITUTION:An external power supply 10 is connected between a transparent electrode 7 and a cathode 1. A photoconductive film 5 is scanned by a focused and deflected electron beam 2. As a result, the scanned surface of the photoconductive film 5 is negatively charged and has its equilibrium potential is setted nearly to the potential of a cathode 1 resulting the photoconductive film is almost charged by the external power supply. When light comes in, the electric resistance of the photoconductive film 5 drops so that the negative charge is increasingly discharged. As a result, an electric charge pattern corresponding to the quantity of the incoming light is formed on the scanning side surface of the photoconductive film 5, and the potential of the surface varies. When the photoconductive film 5 is scanned by the electron beam 2 at the next period, the electron beam landing occurs corresponding to the variation in the potential of the surface, so that a charging current nearly equal to the quantity of the discharged charge flows through current meter 11. For that reason, an optical image is converted into a time-sequential signal current. The storage capacity of the photoconductive film 5 is set at 15 muF/m<2> to 150 muF/m<2>.

Title: Probe head
Inventor: TSUDA KIICHIRO
IPC: G01N29/24
Filed: 1991-05-31
Abstract: PURPOSE:To enable accurate probing of a fault even when the surface of an object of inspection has unevenness, by lowering the height of the axial line of each pin of a gimbal mechanism and by enabling the diameter of a seal member abutting on the surface of the object of inspection. CONSTITUTION:An ultrasonic type probe 1 is inserted coaxially into a cylindrical case 2 and made to scan on the surface of an object 10 of which an internal defect is to be probed. The case 2 is connected to a holder 7 rotatably in all directions with a ring 6 and gimbal mechanism composed of pins 8A and 8B having axial lines perpendicular to each other, interposed. A nut-shaped having a cylindrical seal 5 attached is fitted on the peripheral wall of a cylindrical base 4 and the lower end face of this member abute on the surface of the object and slides. Since the end face diameter of the seal 5 is very large and the height H of the axial line of each of the pins 8A and 8B of the gimbal mechanism from the surface of the object 10 is very small, the tilt of the probe 1 is small when it comes across an uneven part in the course of scanning, deviation from a normal position becomes small as well and thus the reliability of probing of the fault is improved.

IPC: H02J3/38
Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To correctly judge whether the reverse power is at a consumer terminal or at a main and back-up load system at the time when a breaker of a transformer station for a power supply is opened, by discriminating the consumer terminal reverse power detection characteristics of a spot network system by using the line power or a quantity of electricity obtained by subtracting the average power from the line power. SOLUTION: A line power calculating means 421 calculates the effective power Pi and reactive power Q1 for each line from each line current and line voltage. Then, an average power calculating means 422 calculates the average power of all the lines obtained by the line power calculating means 421. Then, a discrimination power judging means 423 calculates the discrimination power for earth line constituted of a difference between the power obtained by the line power calculating means 421 and the average power obtained by the average power calculating means 422, and then a reverse power judging means 424a applies the discrimination powers to the operating conditions for five relay elements to judge whether the power is reverse power or not.  By this method, the reverse power at the consumer terminal and the reverse power at a main and back-up load system at the time when a power supply terminal is opened can be discriminated from each other.

Title: Method for reticle correction
Inventor: NISHIGUCHI TAKAO
IPC: G03F1/72
Filed: 1982-07-23
Abstract: PURPOSE:To correct the deffective part of a reticle by a method wherein the pin-holed defective part of the reticle is shielded from light using a plate having a light-shielding part. CONSTITUTION:The light coming from an exposure light source 1 is turned to paralleled beams of light by a lens 2, reaches a master reticle 4 through the intermediary of a plate 3 partially having a light-shielding part, and it transfers the chip pattern of the reticle 4 on a copy reticle 5. When a master reticle 4 is corrected, a correcting plate 3' having a light-shielding part 10' which is larger than a pin-hole defect 11 is used as a correcting plate 3. Before starting an exposing process, the positioning of the plate 3 with the light-shielding part 10' is performed so that the light used for exposure will not be irradiated on the defect 11 of the reticle 4'. A nondefective copy reticle 5 can be formed when an exposing process is performed after completion of positioning.
