Disclosed herein is an information processor, including: a detecting portion detecting connection between a battery pack and an information processor main body, and outputting connection information to the battery pack; a power source circuit to which an electric power is supplied from the battery pack acquiring the connection information; a manipulation portion adapted to be manipulated by a user; and a stopping portion outputting un-connection information to the battery pack when the manipulation portion is manipulated, and stopping output of the connection information even when the connection is detected by the detecting portion.
摘要:
Polymerizable combinations, comprising at least one first component selected from the group of benzoxazine monomers and at least one second component selected from the group of aromatic esters are described. Further on the use of aromatic esters as additives to benzoxazine monomers as well as methods of coating a device by heating the above mentioned combination, and a device, coated by that way is explained.
摘要:
A SiC semiconductor device having a MOS structure includes: a SiC substrate; a channel region providing a current path; first and second impurity regions on upstream and downstream sides of the current path, respectively; and a gate on the channel region through the gate insulating film. The channel region for flowing current between the first and second impurity regions is controlled by a voltage applied to the gate. An interface between the channel region and the gate insulating film has a hydrogen concentration equal to or greater than 4.7×1020 cm−3. The interface provides a channel surface having a (000-1)-orientation surface.
摘要:
The light directed from a light source to a concave mirror and the light directed from a display device to an eyepiece optical system are intersected by each other in a layout. This allows the light source, the concave mirror, and the display device to be arranged in compactness adjacent to the eyepiece optical system without increasing the optical power of an illumination optical system. As the result, the apparatus can easily be minimized in the thickness or the overall size. A hologram optical element is provided where the relationship between the wavelength range Δλ1 at half of the diffraction efficiency of each of the three primary colors of the light in the hologram optical element and the wavelength range Δλ2 at half of the intensity of each of the three primary colors of the light emitted from the light source is defined by Δλ1
