Title: Semiconductor device
Inventor: RUDORUFU PAURUSU TEIBURUKU
IPC: H01S5/00
Filed: 1992-09-28
Abstract: PURPOSE: To improve the adhesion between a platinum layer and a silicon oxide insulating layer and maintain a low contact resistance between the platinum layer and a semiconductor contact layer by containing a metal with ion radius of a specified value or below, contained in the boundary layer between an electrode layer and the insulating layer adjacent thereto. CONSTITUTION: A metal with an ion radius of 0.110nm or below is made to be contained in the boundary layer between a platinum electrode layer 26 and a silicon oxide insulating layer 22 adjacent thereto of a semiconductor device 1, so that the enthalpy at which a binary compound of platinum and the metal is formed has a negative value. Thus, silicon oxide is composed of the negative large oxygen ions and the positive small silicon ions, and silicon oxide mesh structure is formed by means of some amount of a metal. However, it depends especially on the ion radius of the metal, whether or not the metal has such an ability to accommodate. Scandium, La or Zr is especially suitable for such a metal, and its corresponding platinum-metal binary compound PtX (X is the metal in question) has negative high enthalpy of formation.

Abstract: PROBLEM TO BE SOLVED: To prevent crack and delamination occurrence at the time of burning by adding a base metal with specified average particle size and oxygen content as a main component to a conductive paste and oxidizing the surface of the base metal. SOLUTION: A conductive paste is produced by adding a base metal with 0.1-0.8μm average particle size and 0.5-5.0wt.% of oxygen content as a main component. Ni is preferable as the base metal since the sintering temperature is the same as that of a common dielectric material. In order to add oxygen to the base metal, the base metal is brought into contact with oxygen gas at high temperature. A particle 2 of the base metal exists as aggregated state of a plurality of crystallites in the paste or as single state of respective crystallites.

IPC: G01N25/72
Filed: 1999-08-11
Abstract: PROBLEM TO BE SOLVED: To automatically decide defective and sound parts by performing the image processing of the thermal image of an object being measured in the rising or falling process of an object surface temperature, obtaining each inflexion point of the obtained pixel line, and detecting a region being surrounded by the inflexion points. SOLUTION: A defect inside an object is detected automatically, for example, by a thermal image being measured using an infrared imaging device. The object is heated or cooled, and the thermal image is picked up by a CCD camera or the like in the process. The obtained image data is processed by an image- processing device and is scanned by a scanning device, and the temperature distribution of the obtained pixel line is sent to a computer. The computer obtains the inflection points of the pixel line, such as points B and C, displays them, and at the same time stores them at a specific storage. For example, in the rising process of the object temperature, a part for indicating the inclination of a projection above between the points B and C is a part, where release or the like has occurred inside.  In the falling process of the temperature, a defective part is detected as a recessed part.

Title: Open/close controller for tray in disk changer system and its method therefor
Inventor: HAN MUN HO
IPC: G11B17/24
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To prevent vibration of a tray and focus drop of a disk by controlling a motor so that it gradually increases its driving speed in opening/closing the tray and gradually decrease the speed at the time of finishing the drive. SOLUTION: A control part 130 decreases a driving force of a motor 110 at a starting point to open/close a tray 100 by a moving part 120, and gradually increases the driving force as the tray 100 moves. When the movement of the tray 100 has reached a fixed speed, the motor 110 keeps its driving force at a steady state for the tray 100 to move at a constant speed and reach near a target, halt point. Then, the control part 130 controls the motor 110 to gradually decrease the moving speed of the tray 100 and supplies the motor 110 with a counter-electromotive force before the tray reaches the target halt point. Thus, it is possible to halt the tray 100 at an accurate target point and prevent the tray from vibrating and also prevent the disk from dropping a focus.
