Title: Fault judging method for optical pickup, and optical pickup inspecting device using the method
Inventor: OYAMA KAZUYA
IPC: G11B7/135
Filed: 1996-11-26
Abstract: PROBLEM TO BE SOLVED: To judge the fault of an optical pickup by extracting an image from a spot image while setting such luminance as only the part of a zero dimension is extracted in an ideal spot as a threshold value and comparing the graphic feature of the extracted image with that of the extracted image of the ideal spot. SOLUTION: The direction of the laser beam generated in the semiconductor laser 2 of an optical pickup 1 is changed upright by a raising mirror 5 to form a spot image on a simulation disk 6 surface with an objective lens 4. The formed spot image is magnified by a microscope 7, and after it is sufficiently dimmed with an optical filter 8, it is photographed with a CCD camera 9. The photographed spot image is transmitted to an image processor 11 and is added with gradation information under instruction of a host computer 10 and also after it is processed by a binary processing and an area calculation or the like, whether the optical pickup 1 is normal or not is judged by judging the abnormality or the normality of the spot of the optical pickup 1 as an inspection object based on the area value.

Title: Method for grasping existing segment form
Inventor: TSUCHIYA KOSABURO
IPC: G01B21/00
Filed: 1993-12-15
Abstract: PURPOSE:To easily and correctly grasp the assembling form of an existing segment by moving a sensor in the circumferential direction, obtaining the coordinates from a turning angle and the distance between the turning axis and the inner peripheral surface, and performing coordinate transformation to make an elliptical display. CONSTITUTION:Pre-sensing sensors are disposed in the circumferential direction centering round the turning axis in the horizontal direction in the state of separating from a boring machine 1 in the rear of a shield machine 2 in the existing segments 3, 3. Subsequently, each sensor is stopped at plural positions opposite to the inner peripheral surface of the segment 3 to measure the distance from the sensor to the inner peripheral surface of the segment 3. The turning angle of the sensor and the distance from the turning axis to the segment 3 are calculated to obtain the coordinates on the inner peripheral surface on the segment 3. Subsequently, the center of gravity of the center point group is calculated to compute the amount of eccentricity, and coordinate-transformed to create an approximate ellipse from the coordinate point group. The ellipse is displayed. Thus, an assembling error due to deformation of the segment 3 is avoided to shorten the term of works.

Title: Method and equipment for forming shallow junction in semiconductor device
Inventor: SAITO SHUICHI
IPC: H01L21/265
Filed: 1993-11-22
Abstract: PURPOSE:To obtain a method and equipment for forming a shallow junction in which the properties of a shallow junction formed by plasma ion implantation are improved while stabilizing the carrier concentration. CONSTITUTION:When a PN shallow junction is formed by implanting impurity ions into a semiconductor substrate 11, Si or Ge ions are implanted in plasma (16) to bring about a substantially amorphous state and then P or N type impurity ions are implanted in plasma (17). The semiconductor substrate is then heat treated in the same vacuum, in an inert gas atmosphere of nitrogen or argon, or within 20 hours after it is taken out to the atmosphere thus preventing oxidation of the impurities. This method improves activation of the impurities and increases the carrier concentration thus allowing formation of a shallow junction having improved characteristics and no void.

IPC: H01L41/09
Filed: 1989-12-07
Abstract: PURPOSE:To secure insulation between inner electrodes, and improve the reliability of an element, by laminating many piezoelectric ceramic plates via the respective inner electrodes, and bringing the whole peripheral surface of the lamination body into a mirror surface state.

Abstract: PURPOSE:To make it possible to form a warpless thermally oxided film of a uniform thickness by a method wherein the quantity of light projected on a semiconductor substrate from an infrared ray source is adjusted by a filter means with which the transmittance of infrared rays can be changed spatially by the thickness of a silicon oxide film. CONSTITUTION:A silicon flat plate 4 is arranged between a quartz halogen lamp 1 and a semiconductor substrate 5, the silicon flat plate 4 has a silicon oxide film 8 on the surface of silicon 9, and it is formed in such a manner that the oxide film is thickened in the center part. As the transmittance of infrared rays of the silicon oxide film 8 is low when compared with the silicon 9, the film 8 functions as a kind of infrared filter, and it has the characteristics that the transmittance of infrared rays is high on the circumferential part, and low in the center part. Accordingly, the infrared rays generated by a quartz lamp are modulated in intensity by the silicon flat plate 4, and the infrared rays are applied to the semiconductor substrate 5.

Title: Production of magneto-optical disk medium
Inventor: MATSUO SHINICHIRO
IPC: G11B11/10
Filed: 1988-12-15
Abstract: PURPOSE:To facilitate the sputtering operation of a protective film by using a multiple component oxide of Tb-Si-O as a target at the time of using Tb-SiO2 as the protective film and sputtering the same to form the film thereof. CONSTITUTION:The multiple component oxide 29 of the Tb-Si-O is used as the target 30b at the time of using the Tb-SiO2 as the protective film of the magneto-optical disk medium and executing sputtering of the protective film. Since the Tb and the SiO2 coexist uniformly in the oxide 29, the change in the sputtering rate of the Tb and the SiO2 is equal even if erosion is formed on progression of the sputtering. The decrease in the concn. of the Tb in the protective film formed on the magneto-optical disk is, therefore, obviated. The target is formed by specifying the comspn. of the Tb, Si and O of the oxide 29 to 1:2:4 (atm.% ratio). The specified compsn. ratio is obtd. in this way in spite of the lapse of the sputtering time and the life of the target is prolonged.

Title: Raw material charging bucket soft landing device
Inventor: TAGO ISAMU
IPC: F27D3/10
Filed: 1988-12-16
Abstract: PURPOSE:To make it possible to charge a regenerated material or the like slowly and hence prevent damage to refractory brick by suspending a bucket body by way of a toggle link mechanism which opens and closes a bottom cover, and controlling the position of said bucket body with a supporting frame which makes a vertical motion. CONSTITUTION:A hanging link 5 of a toggle link mechanism is designed to suspend a bucket body 6. Above a furnace body 1 is installed a channel-shaped supporting frame 13 which makes a vertical motion with a frame wire suspended from frame hoists 11A and 11B. The bucket body 6 comes to rest at a thrown material 14 inside the furnace 1 by lowering the bucket body 6. As a hoist 3a is reversed for a specified time based on a signal transmitted from a tension sensing switch S2, the bucket body 6 is brought to a halt at a separated position which allows bottom covers 9A and 9B to be opened perfectly. When a supporting frame 13 further rises, the bottom covers 9A and 9B are spontaneously opened so that raw materials may be thrown into the furnace body 1. Therefore, this construction prevents the damage induced to refractory brick comprising the inner wall of the furnace body and minimizes casting noise as well.
