A flying device includes a propulsion unit, a restrictor and a releaser. The propulsion unit flies the flying device in air. The restrictor restricts the propulsion unit in an open state from rotating more than a predetermined angle during flight of the flying device, the propulsion unit in the open state being rotated from a closed state by the predetermined angle. The releaser releases a restriction by the restrictor.

Shock absorbable flying device, method of flying the same, and recording medium

There is provided a light source unit comprising an excitation light shining device for emitting excitation light, a luminescent plate having a luminescent light emitting area on a base material and adapted to emit a luminescent light of a predetermined wavelength band by excitation light from the excitation shining device, two types of light source devices for emitting light of wavelength bands different from that of the light from the luminescent plate, a light guiding optical system for guiding the light from the luminescent plate and the rays from the light sources to a predetermined plane, and a light source control device for controlling the emission from the excitation light shining device and the light sources, wherein a synthetic light or a single-color light are emitted by controlling the emissions from the excitation light shining device and the light sources by the light source control device.

Light source unit and projector

A cooling unit is provided which cools effectively a plurality of heat sources which are accommodated within small-sized electronic equipment such as a projector. There is provided a cooling unit in which a plurality of base platesare disposed adjacent closely to each other, each of the base plateshas flat plate-shaped radiating finwhich is erected on rear sides thereof, each of the radiating finerected on the base plateshas extending portionswhich extends over the rear sides of the base plateswhich are adjacent to each other, and one or a plurality of heat sources are heat connected to front sides of the base plates

Cooling unit including base plates each having a radiating fins that has an extending portion to extend over an adjacent base plate, and projector

An optical system unit of a projector of the invention includes an illumination side block, an image producing block and a projection side block, the image producing block, in which a DMD display device is fixed which reflects rays of 'off' state light to the outside of an entrance opening of a projection side optical system, has a resin accommodation case and a metallic light absorbing portion which is disposed on an inner surface of the accommodation case, an inner surface of the light absorbing portion has heat resisting properties and light absorbing properties, and the accommodation case has in an upper surface thereof a cooling opening for preventing the overheating of the resin which forms the accommodation case.
