  • Patent number: 11974380
    Abstract: A scanning light source includes a semiconductor light source and a motor, and scans output light of the semiconductor light source in front of a lamp according to the movement of the motor. A constant current driver supplies a driving current ILED to the semiconductor light source according to a light source control signal. A light source control signal generator generates the light source control signal so as to obtain a light distribution pattern that corresponds to light distribution instruction data. A delay time measurement device measures the delay time required for the transition of the on/off states of the semiconductor light source from the change of the light source control signal.

    Abstract: A vehicular headlight (20) includes a first light source unit (41), a second light source unit (61), a temperature sensor (47), and a control unit (110). When the temperature derating is performed on the first light source unit (41) based on the temperature in a state where the light distribution pattern (910) of a low-beam is formed, the control unit (110) controls the power to be supplied to each of a plurality of light-emitting elements (43) so that the light amount of at least a part of the first light with which at least a region (911) of a first light distribution pattern (400) is irradiated decreases as compared with that before the temperature derating.

  • Patent number: 11655118
    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.

  • Patent number: 11267216
    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.

  • Patent number: 11065853
    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.

    Abstract: The invention provides a laminate including a polyimide film and an inorganic substrate, which has a number density of blisters including carbide particles therein of 50/m2 or less, an average height of blisters of 2 ?m or less, a product of the number density of the blisters (blisters/m2) and the average height of the blisters (?m) of 20 or less. The inventive laminate can be obtained by laminating the polyimide film and the inorganic substrate after sufficiently purifying and cleaning to remove foreign bodies made of inorganic substance therefrom, followed by heat treating the laminate at a temperature of 350-600° C. and then rapidly cooling it to carbonize and reduce the organic foreign bodies, and also to rapidly cool the gas contained in the blisters, which leads to reduced height of blisters.

  • Patent number: 10756372
    Abstract: A first proton-donating layer (20a) is a layer having a proton-donative functional group on the surface, for example, a silicon oxide layer. A second proton-donating layer (20b) is also a layer having a proton-donative functional group on the surface, for example, a silicon oxide layer. Negative surface charges are formed on the main surface section of a first base (10a) and the main surface section of a second base (10b), and these negative charges increased the proton conductivity in an aqueous solution fed to a nano channel. Although, in the aqueous solution, proton migration through hopping between water molecules contributes to its diffusion, the negative charges formed on the main surfaces of the bases (10a, 10b) attract protons in the aqueous solution, and the conduction of protons is efficiently achieved in “high-speed transfer regions” formed in the vicinity of the proton-donating layers (20a, 20b).
