Abstract:
A projection display device includes an imager portion which modulates light based on an image signal; a projection lens unit which includes a resin lens and projects the light modulated by the imager portion; a projection port which is formed in a main body cabinet, and passes light from the projection lens unit; an air inlet which is formed in a vicinity of the projection port of the main body cabinet; and an air passing portion which draws in an air through the air inlet and passes the drawn-in air along the projection lens unit.
Abstract:
Disclosed is an electroconductive material which contains at least a vanadium oxide and a phosphorus oxide, and has a crystalline structure composed of a crystalline phase and an amorphous phase, in which the crystalline phase contains a monoclinic vanadium-containing oxide, and a volume of the crystalline phase is larger than that of the amorphous phase.The electroconductive material has a reduced specific resistance and has improved functions as an electrode material, a solid-state electrolyte, or a sensor such as a thermistor.
Abstract:
A glass composition according to the present invention comprises: phosphorus, vanadium and at least one transition metal selected from a group consisting of tungsten, iron, and manganese, the glass composition not containing substances included in the JIG level A and B lists, a softening point of the glass composition being 550° C. or lower.
Abstract:
A projection display device includes: a leg section that supports a main body of the projection display device with respect to an installation surface on which the main body is installed; and a filter section that is disposed on a bottom of the main body and exposes a first air intake surface to the outside. In this arrangement, the first air intake surface is inclined with respect to the bottom surface of the main body in a direction that departs from the installation surface, and air flows into the filter section through a clearance between the first air intake surface and the installation surface.
Abstract:
A projection display device includes an imager; a cooling portion which supplies an air drawn in from an outside of the projection display device to the imager through an air outlet; an air exhaust portion which discharges an air that has passed the imager to the outside of the projection display device; and a circuit board which is disposed at a position opposite to the air outlet with respect to the imager. In this arrangement, the circuit board is disposed at such a position that the circuit board is not overlapped above the imager, when viewed from an aligning direction of the air outlet and the imager.
Abstract:
A projection display device includes a projecting portion which enlarges and projects light modulated by an imager; a projection port which is formed in a main body cabinet, and passes light emitted from the projecting portion; and a cover which covers the projection port. In this arrangement, the main body cabinet is formed with a first attachment portion for attaching the cover thereon in covering the projection port, and a second attachment portion for attaching the cover detached from the first attachment portion thereon.
Abstract:
A projection display device includes a main body cabinet; a shield member which is disposed in the main body cabinet, and shields an electromagnetic wave; an air inlet which is formed in the main body cabinet; and a filter device which removes unwanted matters from an air drawn into the main body cabinet through the air inlet. In this arrangement, the filter device includes a metal filter. The metal filter and the shield member are electrically connected to each other when the filter device is mounted in the main body cabinet.
Abstract:
Disclosed is a constitution formed from an oxide of an element having a smaller work function than aluminum. This oxide is comprises an oxide of vanadium (V), an oxide of an alkaline earth metal and an oxide of an alkali metal. The elements for the alkaline earth metal are comprise one or more elements out of the elements calcium (Ca), strontium (Sr) and barium (Ba) and at least contain barium. The elements for the alkali metal include at least one or more of sodium (Na), potassium (K), rubidium (Rb) and cesium (Cs). When the element vanadium is included as vanadium pentoxide (V2O5), the vanadium pentoxide content is 40-70 wt %. Thus, a glass composition for aluminum electrode wiring with an apparent work function for electrode wiring that is smaller than the work function for aluminum (Al) can be provided without the inclusion of lead.
Abstract:
A low softening point glass composition, which is substantially free from lead, bismuth and antimony and comprises oxides of vanadium, phosphorous, tellurium and iron, a softening point of the composition being 380° C. or lower.
