  • Publication number: 20190134963
    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.

  • Publication number: 20180112592
    Abstract: A valve control device controls a valve drive mechanism on the basis of a degree-of-opening signal for a valve and a startup signal for an engine, and includes: a drive signal generating unit that, when it is determined on the basis of the startup signal that the engine is stated, generates a test drive signal for test-driving the valve before the generation of a normal drive signal associated with normal driving of the valve; and an abnormality determining unit that, on the basis of the degree-of-opening signal during the test driving, determines whether or not an abnormality has occurred in the drive mechanism. The drive signal generating unit stops generating the test drive signal and the normal drive signal when the abnormality determining unit determines that the abnormality has occurred in the drive mechanism.

  • Publication number: 20170123063
    Abstract: A distance measuring device includes a first measurer, a second distance measurer, and circuitry. The first distance measurer measures a distance to a target object; and outputs first distance information indicating a measured distance when the distance measurement is performed under a condition that satisfies a distance measurement condition, but outputs the first distance information indicating a predetermined value when the distance measurement is performed under a condition that does not satisfy the distance measurement condition. The second distance measurer measures a distance to the target object and outputs second distance information indicating the measured distance. When the first distance information indicates the predetermined value and the second distance information satisfies a predetermined condition, the circuitry makes alteration such that the distance measurement condition is relaxed.
