  • Patent number: 7394095
    Abstract: In the present invention, a lower electrode is utilized as a photomask to form a liquid-repellent region having a generally same pattern shape as that of the lower electrode and a liquid-attracting region having a generally reversed pattern shape on an insulating film. A conductive ink is coated and calcined in the liquid-attracting region to form an upper electrode having a generally reversed pattern shape to the lower electrode in a self-aligned manner, eliminating the occurrence of misregistration even when a printing method is used. Consequently, semiconductor devices such as an active matrix thin film transistor substrate can be formed using a printing method.

  • Patent number: 7341133
    Abstract: A hydraulic power transmission is provided with a frictional engagement element as a lock-up clutch between a hydraulic power transmission chamber, housing a pump impeller and a turbine runner, and a servo oil chamber of the lock-up clutch. A lock-up oil passage that supplies lock-up hydraulic pressure to the servo oil chamber is connected to a hydraulic pressure supply circuit that is used in common with a circulation oil passage that supplies hydraulic pressure for circulation to the hydraulic power transmission chamber. An orifice is disposed in the circulation oil passage. It is thus possible to perform lock-up with different supply pressures. A common oil supply for the lock-up oil passage and the circulation oil passage is provided, for example, by disposing a converting circuit that adapts an oil passage connection to hydraulic transmissions with different types of lock-up clutches.

An exposure unit 10 is placed on the back side of the substrate and forms the lyophobic film applied on the substrate into a pattern in alignment with gate electrodes 13. A dropping unit 55 drops a test liquid to a surface of the substrate having a pattern of the lyophobic film formed by the exposure means. A measuring means 58 detects the droplet dropped by the dropping unit. A determining means determines whether the pattern of the lyophobic film formed by the exposure means is proper or not based on the droplet detected by the detecting means.

  • Publication number: 20070284571
    Abstract: An organic thin-film transistor (TFT) with a large carrier mobility includes a drain electrode, a source electrode, which are made of different materials, and a semiconductor layer formed on upper surface of a substrate. Equipment for manufacturing the organic TFT comprises a substrate mounting unit, a painting unit, a light irradiating unit, a sealed container for housing the above units, and a gas supplying unit of an antioxidant gas to the sealed container. The organic TFT to be manufactured is placed on the substrate mounting unit and a semiconductor layer is formed by using the painting unit. The painted semiconductor layer is dried with a light by using the light irradiating unit. When the light with substantially uniform wavelength is irradiated to the drain and the source electrodes, a temperature gradient is caused in the semiconductor layer. Accordingly, an organic TFT with a large carrier mobility can be manufactured.

  • Publication number: 20070281384
    Abstract: An electrode substrate in which a lower electrode and an upper electrode are well positioned by way of an insulating film could not be formed by a printing method since positional displacement is caused. The cost was increased outstandingly when using photomasks for positioning. In the present invention, positional displacement does not occur even when using the printing method since the upper electrode and the lower electrode are positioned in self-alignment. Accordingly, a semiconductor device such as a flexible substrate using an organic semiconductor can be formed with low cost by using the printing method.

  • Patent number: 7289892
    Abstract: The present invention provides inspection of a transmission with higher precision and in a shorter period of time. Before a finished A/T is inspected, a V/B ASSY and an ECU are inspected together by a V/B tester in a subsidiary line. A solenoid current command value (a characteristic value inherent in the A/T) for a linear solenoid of the V/B ASSY is corrected and written into the ECU through CAN communication. Spring load of a return spring SP and stroke of the piston of a hydraulic servo for a frictional engagement element are measured. Actually measured values or corrected values of the spring load and the stroke are stored. In the final inspection of the A/T a finished-product tester reads the stored characteristic values and transmits them to the ECU integrated with the A/T through CAN communication. The characteristic values are then written into the ECU. The finished-product tester inspects the finished A/T product, using the characteristic values thus written into the ECU.
