  • Publication number: 20090273837
    Abstract: The present invention is to provide a retardation film having excellent durability against temperature change or the like and a production method of the retardation film. Particularly, the present invention is to provide a retardation film which realizes both reverse wavelength dispersion and durability and a production method of the retardation film. This is achieved by a retardation film including: a component (A) which is specific cellulose acylate; and a component (B) which is cellulose acylate or cellulose ether having a molecular weight different from a molecular weight of the component (A) and whose residual degree of hydroxyl group is 0.30 or more.

  • Patent number: 7478254
    Abstract: A switching power supply device has a large load power supply line for a CRT circuit, to and from which a dummy resistor for voltage stabilization is connected and disconnected by a switch. In standby state, a control unit turns off the switch to disconnect the dummy resistor from the power supply line. When receiving a power supply ON command input by a user operating a remote control, the control unit turns on the switch to connect the dummy resistor to the power supply line. At a predetermined time after the dummy resistor connection, the control unit makes a regulator active to start providing voltage to a video/audio signal processing circuit with sufficient current providable thereto. This enables to reduce power consumption of the power supply line with the dummy resistor, and to prevent problems caused by insufficient current in transient state from standby state to power supply ON state.

  • Patent number: 7172439
    Abstract: The present invention makes it possible to fix connector pins at low cost. Connector pins penetrate both a holding substrate and a main substrate. The connecter pins can be restrained from an outward radial direction by both wall surfaces of pin holes of the holding substrate, and wall surfaces of through-holes of the main substrate, thus improving upright-standability of the connector pins. The holding substrate is formed of a same raw substrate as the main substrate is formed of, and permanent resists which are laminated on the holding substrate, and ink used for silk screen printing to which the holding substrate is subjected, are made of a same material of the main substrate, so that fire resistance of the holding substrate and fire resistance of the main substrate are same. Therefore, if the main substrate clears a predetermined fire-resistance standard, the holding substrate also inevitably clears the predetermined fire-resistance standard.

  • Patent number: 4953649
    Abstract: A four-wheel steering device for an automobile includes a main turning arrangement for steering main wheels, a subsidiary turning arrangement for sterring subsidiary wheels, and a control system including a motor having terminals thereon, first and second steering angle sensor arrangements for detecting first and second steering angles of the main the subsidiary wheels, respectively, and a control arrangement. The control arrangement is responsive to a state change of the first and second detected steering angles for determining the operating state of the control system. The control arrangement is operable when the control system operates normally to drive and control the motor and thereby the subsidiary turning means so as to steer the subsidiary wheels depending on the steering angle of the main wheels.
