Title: Single-turn induction heating coil
Inventor: IKEDA YASUHIRO
IPC: C30B13/20
Filed: 1987-05-25
Abstract: PURPOSE:To prevent the magnetic field leakage in a gap area, the deterioration of the electromagnetic coupling, and the disturbance of the magnetic field by a feeder tube by providing conductive arc plates in the gap area on the coil peripheral end face so that the gap area can be practically shielded. CONSTITUTION:A pair of symmetrical conductive arc plates 24A, 24B are welded on the bottom side periphery of a coil 20 facing a monocrystal growth zone, and the side of a gap area 23 facing the monocrystal growth zone is practically shielded. The plates 24A, 24B are inclined toward the outer diameter side so as to approach the monocrystal growth zone side. As a result, the electromagnetic coupling between the coil 20 and the monocrystal growth zone is increased, and the crystal growth effect is improved. A feed tube 11 is electromagnetically shielded with the plates 24A, 24B, thus the magnetic field disturbance at the portion can be prevented. The magnetic field leakage in the gap area, the deterioration of the electromagnetic coupling, and the magnetic field disturbance can be thereby prevented.

Title: Coated film inspection apparatus
Inventor: NAGATA TAKESHI
IPC: G01B11/30
Filed: 1986-05-30
Abstract: PURPOSE:To make inspection of quality of a coated film of black primer possible, by detecting and comparing a signal width of scan signals along the diameter of the image in high and low levels from an output of an image developing member which has picked up a coated film and issuing a control signal. CONSTITUTION:An optical sensor apparatus 5 develops an image of a primer film P coated by a brush. A laser light source 8a irradiates a coherent light beam onto the film P to its full width and the reflected beam develops an image by for instance a CCD 9. The reflected image, depending upon surface condition of the film P, becomes an image generated with moire-interference fringes having luminance at the level equal to, higher or lower than that of the irradiated beam. Next, a processing unit 10 takes out from this image a signal by scanning its central part and obtains a scan signal SS running along a diameter of the image and detects 21 signal widths SA, SB in comparatively high and low levels A, B inside voltage levels of the signal SS and by comparison 22 of them and issues a control signal S1 when the width SA drops down to a constant ratio or less of SB. The signal S1 places the specified emergency alarm in the ON position or arranges in such a way that the emergency process can be performed.

Title: Tape carrier connection method
Inventor: NIIMI HIDEKI
IPC: H05K3/36
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To suppress the amount of extension of a tape carrier upon heat pressing by performing the heat pressing such that when a temperature applied to an anisotropic-conductive adhesive sheet becomes a particular ratio of a final temperature, a pressure force applied to the anisotropic-conductive adhesive sheet is a particular ratio of a final pressure force. SOLUTION: A connection terminal 6 of a tape carrier 5 and an Al electrode 2 of a liquid crystal display panel 1 are aligned with each other via an anisotropic-conductive adhesive sheet 3, and heat-pressed by a constant-heating type bonding tool 7 from a position over the tape carrier 5, such that the terminal 6 and the electrode 2 are electrically connected. In this case, the heat pressing is performed such that when the temperature applied to the sheet 3 reaches 85% of the final temperature the pressure force applied to the sheet 3 is 80 to 85% of the final pressure force. By this arrangement, the rising of the pressure force applied to the sheet 3 is quickened, and the sheet 3 can be pressurized with a pressure force close to the final pressure force before the carrier 5 extends by the heat applied to the carrier 5. Thus, the amount of extension of the carrier 5 can be suppressed.

Filed: 1985-06-11
Abstract: PURPOSE:To prevent airflow path from being blocked due to frosting and improve heat transfer performance by a method wherein flat plate type refrigerant flow paths are arranged in parallel to the direction of air-flow and the interval of the flow path is narrowed toward the downstream side while a plurality of longer fin members are provided as the path approaches to the downstream side to improve heat transfer coefficient and increase the heat transfer area of the airflow path. CONSTITUTION:The airflow flows between the fin members 6 along the flat plate type refrigerant flow path 5 while effecting heat exchange between refrigerant, which enters from a refrigerant inlet pipe 7 and flows into a direction opposing to the direction of airflow. Accordingly, a dead water area in the refrigerant flow path will never affect badly to the fins and the fins are utilized effectively to increase the heat transfer performance. In the area having a wide interval between fins, in which the flow can be regarded to be the flow on a single flat plate, the dimension of the fin in the direction of airflow is shortened to contrive the improvement of an average heat transfer coefficient while the dimension in the airflow direction is elongated to increase the heat transfer area, prevent the airflow path from being blocked due to frosting phenomenon and realize the improvement of heat transfer performance in the area wherein the interval between fins is narrow and the flow is closed to the flow between parallel flat plates.
