Title: Partial discharge detector
Inventor: MATSUMOTO SATOSHI
IPC: G01R31/12
Filed: 1987-05-18
Abstract: PURPOSE:To facilitate the detection of a partial discharge signal which is closer to the actual state with high sensitivity by arranging tuning circuits in parallel and using an elastic surface wave device as a resonance circuit. CONSTITUTION:The signal generated by partial discharge occurring to an insulator or electrode is inputted from an antenna 1 and inputted to an amplifier through a filter 2. The output of the amplifier 3 is inputted to the tuning circuits 4-7 which have resonance frequencies f1, f2...fn. The outputs of the circuits 4-7 are outputted through a logic circuit 30 which is counted only when some of the circuits obtains >=2 outputs. The circuits 4-7 resonate at resonance frequencies corresponding to a specific frequency component generated by the partial discharge and their outputs are led to the circuit 30. In this case, elastic surface wave devices are used as the circuits 4-7 to easily obtain high Q.

IPC: G03H1/04
Filed: 1983-06-30
Abstract: PURPOSE:To obtain a distinct stereoscopic reproducing image and to form an image of a virtual object on a hologram by providing a hologram medium, an optical space modulating element and a reference light control means. CONSTITUTION:The slice image 1 of a virtual object is recorded on the optical space modulating element 2 by an optical means, etc. When coherent light 3 is irradiated from the left side of this optical space modulating element 2, the diffracted light 4 containing the information of the slice image 1 appears on its right side. On the other hand, the reference light irradiated from a reference light source 5 is made incident onto a hologram medium 6, and this reference light and the diffracted light form an interference image on the hologram medium 6. In this state, the slice image can be reproduced stereoscopically by moving the position of the reference light source 5 without moving an object. In this way, a distinct stereoscopic reproducing image is obtained, and virtual object is image formed on the hologram.

Title: Digital demodulation circuit
Inventor: SUGAWARA HIROKI
IPC: H04B1/707
Filed: 1992-04-14
Abstract: PURPOSE:To obtain a digital demodulation circuit suitable for the demodulation of a broad band modulation wave signal. CONSTITUTION:An analog LPF 1 implements band limit by using fS1/2 as a cut-off frequency of an input signal to eliminate the effect of aliasing. An A/D converter 2 quantizes the signal subject to band limit by using a sampling frequency fS1 being twice the highest effective frequency of a broad band modulation wave signal. A demodulation computing element 4 implements demodulation arithmetic operation by digital signal processing based on an output signal of a converter 2 at the same sampling rate and an output signal of a modulation signal generator 3. A comb-line filter 5, a decimeter 6 and an FIR filter 7 form entirely a digital LPF of a low-degree number, applies band limit processing as to an output of the computing element 4 thereby improving the S/N, that is, expanding the dynamic range. A decimater 8 applies interleave processing to the output of the filter 7 to decrease a sampling rate without deteriorating the S/N and to facilitate the processing at the post stage.

Title: Semiconductor heat treatment jig
Inventor: SHIMAZU MITSURU
IPC: H01L21/18
Filed: 1983-07-01
Abstract: PURPOSE:To prevent lateral displacement of two sheets of semiconductor substrates by placing a weight, which is provided or removed in order to inhibit the movement of jig in parallel to the plane, on the two sheets of semiconductor substrates on the jig body. CONSTITUTION:The semiconductor substrates A, B are placed on the upper surface of jig body 1 with the mirror surfaces of them stacked one upon another. Moreover, a weight 2 is placed on the substrates A, B. The weight 2 is placed on the body 1 so that the protruded insertion holes 4, 4,... of weight 2 match the protrusions 3, 3,... of the body 1. Thereby, the protrusion 3 engages with the hole 4 and the weight 2 is placed on the substrates A, B. The weight 2 does not move in the direction parallel to the surface owing to engagement of protrusion 3 and hole. The substrates are subjected to the heat treatment under such condition. The substrates 3, 4 receive the heat treatment without any displacement and since a high pressure is applied to the mirror surfaces in contact, a less amount of element having a high vaporization pressure is vaporized.

Title: Scanning image-forming mirror for optical scanning
Inventor: ATSUMI HIROMICHI
IPC: G02B26/10
Filed: 1995-05-18
Abstract: PURPOSE: To obtain a new scanning image-forming mirror for optical scanning in which the part of a reflection area which is not used effectively at the time of an optical scanning is realized to be small and to be in small width by shifting the center line in the width direction of the mirror corresponding to a subscanning direction from the crossing line between a large circular plane and a spherical surface. CONSTITUTION: The shape of the reflection surface 401 of a scanning image-forming mirror 400 is a 'spherical shape'. That is the reflection surface 401 is the one part of a sphericality 403 and has the slim piece of a mirror shape cut out to be a tanzaku- shape (the shape of the strip of fancy paper) by two planes 407, 409 parallel to the large circular plane 405 in the sphericality 405. Then, the mirror 400 is arranged so as to parallel correspond to the corresponding direction of main scanning and the center line in the width direction of the mirror corresponding to a subscanning direction (the crossing line between the plane 411 dividing the interval in between planes 407, 409 into equal halves) is shifted from the crossing line between the large circular plane 405 and the sphericality 403.  Thus, the size of the width direction corresponding to the subscanning direction is effectively reduced and the scanning image-forming mirror 400 is effectively miniaturized.

Title: Extracting method for hole
Inventor: SATO HAJIME
IPC: G06K9/48
Filed: 1986-05-27
Abstract: PURPOSE:To extract the hole of an image with a simple processing by bringing the image to which a direction code is given in accordance with a prescribed rule, to a raster scan, to a contour white picture element of a binary image of a character, etc., tracking a contour in accordance with a search order determined in advance, and extracting the hole. CONSTITUTION:Since the direction code of start point coordinates 10, 1 is 4 at present in case of searching in order of -1--5, a picture element to which a direction code 8 is attached exists in a point of -1, namely, in coordinates of 9, 2, therefore, a tracking point is moved to this picture element. Thereafter, in the same way, the movement of the tracking point and the processing of clear are repeated successively, and by returning to the start point coordinates, one contour tracking is ended. As for the raster scan of a second time when the direction code of coordinates 10, 5 is 6 first, the probability to which a hole exists therein is very high, and accordingly, it is counted as a hole. The raster scan is executed continuously and the direction code is disappeared, and also, the raster scan is executed and collides with the next start point, and when the direction code of its start point is 6 (point of coordinates 15, 18), it is counted additionally as the hole.

Abstract: PURPOSE:To remove particulates sucked and fixed onto the back of a semiconductor substrate, and to reduce particulates adhering on the surface of the semiconductor substrate in a subsequent semiconductor-device manufacturing process largely by ultrasonic-treating the semiconductor substrate, to one surface of which a lattice strain layer is formed by mechanical damage, in a solution containing hydrofluric acid. CONSTITUTION:A solution such as a 4.9% hydrofluoric acid solution 1 is circulated by a pump 3 through a filter 2, and an silicon substrate 5 supported by a wafer carrier 4 is exposed to the liquid having a constant flow rate at all times. Consequently, particulates floated from the silicon substrate 5 by the 4.9% hydrofluoric acid solution 1 and ultrasonic waves generated by an ultrasonic generator 6 can be removed from the silicon substrate 5 as they are. The liberation and removal of particulates fixed to the silicon substrate 5 are conducted simultaneously, thus shortening the processing time and reducing the space of a device.
