摘要： An illumination apparatus includes a fluorescence unit, laser light irradiation means, and a beam integration unit. The fluorescence unit has a plurality of phosphors, in which the colors of fluorescence generated due to excitation differ, arranged in different regions. The laser light irradiation means irradiates laser light onto the regions of each color of the fluorescence unit while changing the position at which the laser light strikes the fluorescence unit. The beam integration unit integrates fluorescence from each region of the fluorescence unit on a display panel.

摘要： The purpose of the present invention is to provide a device that is small in size and low noise, in which heat from a light emitting element such as an LD or an LED is efficiently dissipated. A light source device includes a first light emitting element, a base plate, and an air flow device for sending out air. The base plate, which is thermally connected to the first light emitting element, has a flat surface formed around the first light emitting element to face the emitting direction of light output from the first light emitting element. The air flow device generates a flow of air toward the flat surface of the base plate in a direction perpendicular to the flat surface.

摘要： A magnetic head positioning mechanism is provided which is excellent in shock-resistance and can achieve high positioning accuracy. By constructing the magnetic head positioning mechanism so that a fine actuator section is composed of an actuator spring made from a thin steel plate, a base plate made from a thick steel plate to be junctioned to the actuator spring, stiffness of the fine actuator section in a vertical direction can be improved with flexibility of a driving spring section mounted on the actuator spring being still kept, that is, with sufficient positioning accuracy and satisfactory stroke being maintained. Moreover, by designing a strength of the fine actuator section so that the actuator spring and a holder arm do not overlap when the base plate is connected to the holder arm, the fine actuator section can be made thin and implementing of the fine actuator section among narrow plates in a positioning device is made easy.
