摘要:
A projector includes: a light source device; a light modulation device that modulates a luminous flux output from the light source device; a projection optical device that magnifies and projects the luminous flux modulated in the light modulation device; and an exterior casing that accommodates the light source device, the light modulation device, and the projection optical device arranged within, the projector is arranged so as to be installed in a desktop mount position in which the projector is mounted on a predetermined location and a ceiling suspension position in which the projector is provided opposite in the vertical direction relative to the desktop mount position, the light source device includes a light source device main body having a light source lamp in which discharge emission is performed between a pair of electrodes and an elliptic reflector having a nearly ellipsoidal reflection surface and converging and outputting a luminous flux radiated from the light source lamp in a certain direction, and a parallelizing lens that parallelizes the converged light of the elliptic reflector, and a lens supporting part that supports the parallelizing lens and makes a position of the parallelizing lens relative to the light source device main body changeable according to the position of the projector is provided.

A device includes: an objective lens that serves as a lens having a first numerical aperture when a first optical beam corresponding to a first optical disc converges on the first optical disc while serving as a lens having a second numerical aperture when a second optical beam corresponding to a second optical disc converges on the second optical disc; a section that generates a reflection optical signal from the first or second optical beam reflected by the first or second optical disc; and a section that determines whether an unknown disc is the first optical disc based on a degree of matching between the waveform of the reflection optical signal obtained when the first optical beam is emitted to the first optical disc, and the waveform of the reflection optical signal obtained when the first optical beam is emitted to the unknown disc.
摘要:
A drum brake apparatus is provided with a backing plate, a brake shoe, a shoe guide portion formed integrally with a backing plate by cutting-up, a guide surface on a rear surface of the shoe guide portion, an engagement projection that is formed on the brake shoe and slidably engages with the guide surface, and end portions that is formed on the shoe guide portion at both ends of the shoe guide portion in a circumferential direction of the drum brake apparatus and is continuous to the backing plate. Uplift of the brake shoe from the backing plate is prevented by engagement between the guide surface and the engagement projection.

An information processing device includes: a display control unit that causes a display unit to display either a first screen for receiving an instruction for selecting image data to be sent or a second screen for receiving an instruction to obtain image data using an image reading unit; a first screen switching unit that, if an instruction for selecting image data to be sent is received while the first screen is displayed on the display unit, switches the first screen to the second screen in response to the instruction; and an image data obtaining control unit that, if the first screen is switched to the second screen by the first screen switching unit, and an instruction to obtain image data using the image reading unit is received while the second screen is displayed on the display unit, causes the image reading unit to obtain the image data.
摘要:
A hard tissue repairing material includes zirconia as a base material. A surface of the base material has a hydrophilic group. The hydrophilic group is bonded to zirconium atom in the base material. The base material may contain at least an ionic component that is selected from a group consisting of calcium ion, sodium ion, potassium ion, and phosphate ions within the surface. A hard tissue repairing material may include zirconia as a base material and a layer of a main component of an apatite. The layer of the apatite may be formed on a hydrophilic group bonded to zirconium atom in the base material.
