A circuit module includes: a lighting control circuit that controls lighting of a semiconductor light emitting element; a first heat radiating member on which the lighting control circuit is mounted; a second heat radiating member that is separated from the first heat radiating member and has a surface on which the semiconductor light emitting element is mounted; and a connecting mechanism having both a housing that connects the first heat radiating member and the second heat radiating member together and a conductive portion that transmits a signal from the lighting control circuit to the semiconductor light emitting element. The housing is formed of a material having a coefficient of thermal conductivity lower than those of the first heat radiating member and the second heat radiating member.

In an automotive headlamp, a light-emitting module is configured such that a light-emitting element and a control circuit unit for controlling the lighting of the light-emitting element are structured integrally with each other. A control circuit unit in a position anterior to the light-emitting element in a lamp unit is located below a shade section so that the control circuit unit can be clear of the path of light used to form a low beam light distribution pattern of the light emitted by the light-emitting element. In this setting, the light-emitting element is so located that a main optical axis Ax2 is perpendicular respect to an optical axis Ax1 of the lamp unit and that a light-emitting portion of the light-emitting element protrudes higher than the control circuit unit in the direction of the main optical axis Ax2.

摘要:
Container for accommodating small article(s) comprises: a container body including flange portion wherein connecting slits are formed; and a container lid element including lateral wall region having projected connecting pieces. A trim cover assembly of the seat includes: a peripheral end area or margin defined in a container mounting hole formed in the trim cover assembly; and connecting slits formed in that margin. In assembly, the connecting pieces are inserted through those flanged portion, while simultaneously the margin of trim cover assembly is sandwiched between the flanged portion and lateral wall region. Those free ends are flattened to connecting slits, respectively, so that free ends of the connecting pieces project from the connect together all the container body, container lid element and trim cover assembly. Finally, the trim cover assembly is attached upon a foam padding, with the container body inserted in a recession of the foam padding.

An elastic-wave filter device includes a first piezoelectric substrate, a second piezoelectric substrate, a first pillar-like wiring electrode, and a second pillar-like wiring electrode. The first and second substrates have a first and a second IDT electrodes on their top faces respectively. A lateral face of the second substrate confronts a lateral face of the first substrate. The first pillar-like electrode and the second pillar-like electrode are formed above the first and the second substrates respectively, and are electrically connected to the first and the second IDT electrodes respectively. The first substrate is thicker than the second substrate. A distance between a plane including the top face of the first substrate and a plane including the top face of the second substrate is smaller than a distance between a plane including an underside of the first substrate and a plane including an underside of the second substrate.

A vehicle lamp includes a semiconductor light emitting device, a thermally conductive portion which is in contact with the semiconductor light emitting device, a heatsink which dissipates heat generated by the semiconductor light emitting device, and a housing in which the semiconductor light emitting device, the thermally conductive portion and the heatsink are accommodated. The heatsink includes a base and plate fins arranged at intervals to protrude from the base. Each of the plate fins includes a plate surface facing the plate surface of an adjacent one of the plate fins and upwardly extending in a direction along the base. A plane parallel to at least one of the plate surfaces of the plate fins may be oblique with respect to a vertical direction. An inner surface of the housing may be oblique with respect to the vertical direction in a region above the plate fins.
摘要:
An image forming apparatus which executes an image creation on the basis of image creation data including a first document identifier has: an input unit which inputs the image creation data; a storing unit which previously stores a second document identifier for limiting an output; and a discriminating unit which discriminates permission or inhibition of the output on the basis of the second document identifier stored in the storing unit and the first document identifier included in the inputted image creation data. The image creation is performed on the basis of only the image creation data which has previously been permitted, thereby preventing the unnecessary image creation from being executed.
