  • Patent number: 7084229
    Abstract: A silicone composition for a release agent, which comprises (A) an organopolysiloxane having at least two alkenyl groups bonded to a silicon atom and at least one fluorine-containing substituent bonded to a silicon atom, in one molecule, and having a fluorine content of from 20 to 40% by weight, (B) an organohydrogenpolysiloxane having at least three hydrogen atoms bonded to a silicon atom in one molecule, (C) a straight-chain perfluoropolyether anti-foaming agent, and (D) a platinum group metal catalyst. Even when the silicone composition is diluted with a non-fluorine-type solvent, it is possible to avoid foaming (the reason for pin holes and repelling) does not occur during roller coating. Moreover, the silicone composition provides a cured coating which needs only a low peel force and hardly gives reduction in the residual adhesive ratio.

  • Patent number: 6951593
    Abstract: A laminating device 10 includes a vacuum grid 19 for holding a glass substrate 12, a curved pad 20, facing the glass substrate 12, for holding a laminated element 16 of a wafer 13 and an adhesive tape 15, and a driving element 22 for moving the curved pad 20 toward the vacuum grid 19. The curved pad 20 has a curved surface region 46 so that the distance to a smooth surface region 39 of the vacuum grid 19 is gradually increased from the center C toward the outside. By the driving element 22, the vacuum grid 19 and the curved pad 20 become close to each other in a substantially vacuum chamber. As a result, the glass substrate 12 and the laminated element 16 are gradually laminated to each other while removing a very small amount of air that may be present therebetween to the outside.

  • Patent number: 6908301
    Abstract: A fuel injector (11) supplies liquid fuel to a catalytic combustor (9) of a fuel reforming device during startup of a fuel reforming device. A controller sets the injection amount (Qf) for liquid fuel to a first injection amount (Qf1) during a predetermined time (t1) after starting fuel injection. After the predetermined time, the injection amount (Qf) is set to a second injection amount (Qf2) which is larger than the first injection amount (Qf1). When the elapsed time after starting fuel injection is smaller than a value (t1), the discharged amount of uncombusted fuel is reduced by setting the injection amount (Qf) to a minimum injection amount (Qf1) which allows ignition and combustion in the catalyst.

  • Publication number: 20050115751
    Abstract: Load sharing rates of an internal combustion engine and an electric motor of a hybrid powered vehicle are definitely controlled to improve fuel efficiency of the vehicle during an auxiliary running with using power of the electric motor together with power of the internal combustion engine when a pressing amount of an accelerator pedal of the vehicle is small. In response to a pressing amount information of the accelerator pedal inputted to a hybrid control circuit, the hybrid control circuit calculates the load sharing rates of the internal combustion engine and the electric motor by referring to a preliminarily set control map and controls the motor according to its load sharing rate. The hybrid control circuit sends an electric signal corresponding to the load sharing rate of the internal combustion engine to the internal combustion engine control circuit, instead of the pressing amount information of the accelerator pedal.
