  • Publication number: 20200331522
    Abstract: An actuator that applies force to a member associated with steering, and a control device that controls the actuator, have duplex configuration. First and second control devices compute the same controlled variable as first and second controlled variables, respectively. In a normal mode, the control device controls the actuator according to the first controlled variable. The first and second control devices send and receive respectively computed controlled variables to and from each other via communications. When a discrepancy arises between the first and second controlled variables, or an abnormality occurs in communications between the first and second control devices, the operating mode is switched from the normal mode to an independent mode. In the independent mode, the first and second control devices control the first and second actuators, according to the first and second controlled variables, respectively.

  • Publication number: 20200180259
    Abstract: [Problem] To provide a polyimide film laminated substrate in which stable peeling with a constant low force from an inorganic substrate is enabled when a polyimide film is to be peeled from an inorganic substrate even after heat treatment at a temperature exceeding 500° C. is performed. [Solution] Silane coupling agent treatment is performed on an inorganic substrate on which a thin film of an aluminum oxide, a thin film of a composite oxide of aluminum and silicon, a thin film of molybdenum or tungsten, or an alloy thin film of molybdenum and tungsten is formed continuously or discontinuously on a part of at least one surface thereof, and a polyimide film layer is further laminated on the silane coupling agent layer. In the obtained laminate, the part where the aluminum oxide thin film layer is present functions as an easily-peelable layer, the part where no aluminum oxide thin film layer functions as an easily-bondable part.

  • Publication number: 20200180888
    Abstract: The purpose of the present invention is to provide a storage state in which a reactive compound layer can be stably maintained in a polymer film having a reactive compound layer on the surface. The film roll is obtained by winding together: a first polymer film having a reactive compound layer on the surface, and a second polymer film having a surface roughness (Ra) of 0.1 ?m or more and a modulus of elasticity of 300 MPa or more and 10 GPa or less. The film bundle is obtained by laminating the first and second polymer films. Preferably, storing the film roll and the film bundle at a low temperature enables a thin layer of a reactive compound to be stably maintained.

    Abstract: A laminate mainly made of polyimide with low thermal expansion, high mechanical strength, and high heat resistance, and a method for manufacturing the same are provided. A surface of a polyimide film is activated and then treated by a silane coupling agent. Subsequently, the obtained silane coupling agent-treated polyimide films are superimposed, and pressure and heat are applied to the superimposed polyimide films so as to manufacture a polyimide film laminate. The obtained polyimide film laminate has a cross-sectional structure of superimposing polyimide film layers and silane coupling agent condensate layer(s) alternately to each other. Adhesive strength between the polyimide films of the polyimide film laminate of the present invention does not change largely from initial adhesive strength even after heat treatment at 400° C. for 15 minutes. Further, the polyimide film laminate exhibits a high bending elastic modulus and impact resistance.

  • Patent number: 9020281
    Abstract: Two imaging optical systems are provided. The two imaging optical systems are configured to have a difference in a ghost appearance condition under the same imaging condition by differentiating at least one of the angle, the resolution, and the variation adjustment in production. In Step S1, images captured by the two imaging optical systems are stored. In Step S2, corresponding positions of each respective portion of a subject between the two imaging optical systems are obtained. In Step S3, images at the corresponding positions are compared with each other for determining a bright portion having a deviation in a luminance value, as a ghost portion. In this configuration, it is possible to accurately detect a ghost generation position on a real-time basis.
