Title: Pack of vacuum insulation material
Inventor: UEKADO KAZUTO
IPC: F16L59/06
Filed: 1992-10-13
Abstract: PURPOSE:To improve thermal insulating characteristics by constituting a pack from a core material obtained from rigid urethane foam of continuous bubble structure prepared by expansion molding by means of a double conveyor wherein differences are provided in moving velocities between an upper conveyor and a lower conveyor and removing a skin layer therefrom, a container covering the core material, and adsorbents. CONSTITUTION:A pack is composed of a core material 8 having continuous bubble structure, a container 5, and adsorbents 9. Rigid urethane foam having continuous bubble structure prepared by means of a double conveyor 13 is carried by a lower conveyor 12, while it rises upwards, and the foam is pressed by upper conveyors 11 having different moving velocity from that of the conveyor 12, so that the foam is subjected to shearing forces, whereby a bubble structure oriented in the same direction as the advancing direction of the conveyor is obtained. As a result, by forming the core material 8 from rigid urethane foam having been cut, degree of orientation of cell is enhanced and thermal insulating characteristics can be improved.

Title: Die bonding
Inventor: HIRANO MASATO
IPC: H01L21/52
Filed: 1989-10-20
Abstract: PURPOSE:To enable solder to spread over all the rear of a chip at scrubbing to firmly bond the chip to a heat sink by a method wherein is made to blow against the molten solder dripped on the heat sink to spread it all over the heat sink. CONSTITUTION:When a semiconductor chip 1 or the like is bonded onto a heat sink 3, gas is made to blow against molten solder 2 dipped on the heat sink 3 to spread it over the heat sink 3, whereby the molten solder 2 is made to spread over the whole chip 1. For instance, high temperature reducing gas is made to blow intermittently from a nozzle 4 against the molten solder 2 dipped on each of the heat sinks 3 to spread the molten solder 2 over the heat sink 3. Then, in this state, scrubbing is carried out, the solder 2 spreads over all the rear side of the semiconductor chip 1, and the chip 1 is firmly bonded to the heat sink 3. These processes are all done in a reducing atmosphere.

Title: Film capacitor for low voltage of 200vdc
Inventor: OSAWA YUKIO
IPC: H01G4/18
Filed: 1998-08-12
Abstract: PROBLEM TO BE SOLVED: To eliminate works of impregnating and sealing a capacitor to enable simplification of its manufacturing steps and exchange of the capacitor, without melting solder. SOLUTION: A capacitor element rolled up with a polypropylene film is accommodated in a plastic case, covered with a heat-shrinkable tubing to use a band for mounting of the capacitor, or a connecting socket is soldered to tip ends of lead wires of the capacitor to facilitate exchanges of the capacitor. Since the capacitor element does not absorb moisture the need for impregnating or sealing the capacitor is completely eliminated.

Title: Method and device for preventing collision of running object
Inventor: MIYAUCHI KIYOSHI
IPC: G06T7/60
Filed: 1991-10-22
Abstract: PURPOSE:To Judge obstacles from a running vehicle, wherein only those objects which are likely to cause collision are judged as obstacle. CONSTITUTION:A camera and an image processing device 4 to be fed with two-dimensional image information from the camera 2 are mounted in a 1st car 1, wherein the output side of the image processing device 4 is connected with a brake unit 5 of the 1st car 1.

The device 4 calculates from time to time the change in the area of the image of 2nd car 3 and the change in the position of the center of gravity. When the area of the image enlarges gradually and the position of the center of gravity has reached the center of the scope which is caught by the camera 2, the device 4 actuates the brake unit 5 to apply brakes to the 1st car 1. Thus collision is prevented.

Title: Method and device for display of screen
Inventor: OTSU TAKASHI
IPC: G06T11/80
Filed: 1989-10-20
Abstract: PURPOSE:To obtain an effective working environment by providing an enlarged window control part which produces such data that changes the display position of an enlarged picture window only when a designated position is largely changed with the coordinate position inputted by a user defined as an input and otherwise does not change the display position of the window. CONSTITUTION:An enlarged window control part 2 receives a coordinate posi tion signal 11 and outputs an enlarged window display position signal 12 after the control of the enlarged window display position. When an enlarged area is desginated with an instruction of a user, an input part 1 sends the signal 11 to the part 2. Then the part 2 compares the signal 11 received previously with the signal 11 received presently to decide whether the position of an en larged window should be changed or not. That is, the redundant shift of the enlarged window is eliminated and the enlarges window is shifted to a position near a designated point where the user's work is not disturbed when the user changed largely the designated position. Thus, it is possible to offer a highly efficient working environment to the user.
