摘要： There is provided a digital broadcasting receiver apparatus in which a temperature in the area surrounding a removable HDD does not become a high temperature during an operation regardless of whether it is disposed horizontally or vertically. A component with a large heat generating quantity and a component with a small heat generating quantity are installed in respective spaces inside a case. An adapter of the removable HDD is mounted to dispose the removable HDD in a space in which a component with a small heat generating quantity is mounted, thereby preventing the temperature in the area surrounding the removable HDD from becoming a high temperature.

摘要： A projection optical system for magnifying an image on a primary imaging plane onto a secondary imaging plane includes a first optical system for forming an intermediate image and a second optical system including a concave reflecting surface disposed between the intermediate image and the secondary plane. The first optical system includes first and second groups respectively having negative and positive power, an aperture, and a third group having positive power from the intermediate image. The surfaces of the first and second optical systems have rotational symmetry about a light axis. A ray traveling from the center of the primary plane to the center of the secondary plane intersects the light axis, is reflected off the reflecting surface, intersects the light axis again, and reaches the secondary plane. The following conditions are satisfied: 0.5

摘要： A projection image display device includes a light source; an illumination optical system that uniformly irradiates a surface of an image modulating element (primary image surface) with a light beam emitted from the light source; and a projection optical system that performs with respect to a screen (a secondary image surface) extended projection on image information provided at the primary image surface and modulated by the image modulating element. The projection optical system includes a first optical system having a positive refractive power, and a second optical system having a concave reflecting surface. The first optical system has a common optical axis at which all optical components of the first optical system have rotationally symmetric surfaces, and a screen shift function that causes the secondary image surface to be moved by moving at least one of the optical components of the first optical system substantially perpendicularly to the optical axis.

摘要： A method for manufacturing a laminated electronic component is performed such that a water-repellent agent is applied to end surfaces at which ends of internal electrodes are exposed so as to be filled in spaces along interfaces between insulating layers and the internal electrodes. Subsequently, an abrading step is performed such that the internal electrodes are sufficiently exposed at the end surfaces and an excess water-repellent agent is removed therefrom to enable plating films to be directly formed on the end surfaces.
