Abstract: An object is to provide a compound that can be a novel curing agent. The compound suppresses volatilization of the curing agent that can lead to a decrease in function of a prepreg, contamination of equipment for producing the prepreg, and in addition a decrease in production yield of the prepreg, and further contributes to improving dielectric properties. As a solution, a tris(allyl ether) compound represented by general formula (1) below is provided.

Abstract: A FrontHaul Multiplexer (FHM) for relaying communications between a signal processing device and a plurality of radio devices includes a storage unit that stores a table in which device identification information of each of the plurality of radio devices is associated with beam identification information assigned to the radio device; a scheduling information reception unit that receives, from the signal processing device, scheduling information of a user terminal performing radio communications with the plurality of radio devices; a determination unit that acquires from the table the device identification information associated with the beam identification information of uplink included in the scheduling information and then determines from the acquired device identification information the radio device in charge of the user terminal; and a transmission unit that transmits to the signal processing device an uplink signal transmitted from the determined radio device.

Abstract: Disclosed herein is a heat radiating structure for radiating the heat generated by a lamp in an image projecting apparatus for projecting an image onto a screen to display the image thereon, including a heat sink for radiating heat generated by the lamp, the heat sink including heat transfer means for transferring the heat from the lamp, the heat transfer means being held in close contact with the lamp, heat storage means for storing the heat transferred from the lamp through the heat transfer means, and a plurality of fins serving as heat radiating means for radiating the heat stored by the heat storage means, wherein the heat transfer means, the heat storage means, and the heat radiating means are of a separable structure.

Abstract: In an LCD projector or other projection type display apparatus which uses a lamp such as a xenon lamp for a light source, the lamp is cooled efficiently without increasing ambient noises or without causing the whole apparatus to become large-sized, and at the same time the lifetime and the reliability of a fan which cools the lamp is made improved. When fans 3 and 4 which are disposed on a front side of the lamp mounted with a heat sink 1 rotate, external air of ordinary temperature is taken inlet and guided into ducts 5 and 6 so as to be blown onto the front face of the lamp by means of the fans 3 and 4. Then, high temperature air which was warmed by being blown onto the lamp is exhausted from an outlet to the outside.

Abstract: A projection type display device, in which efficient cooling is performed in a remarkably silent manner, includes: a light source unit; an optical unit for modulating illumination light output from the light source unit based on input image information; two power source sections and; a box for housing the optical unit, the light source unit and the power source sections; and a cover member for entirely covering at least an upper surface of the box, wherein an outlet for externally exhausting air in the box by using axial fans is provided only on a bottom side of the box. Liquid crystal panels that are held by the optical unit frame absorb the illumination light from the light source unit and thus have different increased temperatures.

Abstract: A projection type display device, in which efficient cooling is performed is operated so that the display device is operated in a remarkably silent manner, is provided. The projection type display device includes: a light source unit 66; an optical unit 50 for modulating illumination light output from a light source based on input image information; power source sections 81 and 82; a box 4 for housing the optical unit 50, the light source unit 66 and the power source sections 81 and 82; and a cover member 5 for entirely covering at least an upper surface of the box, wherein an outlet for externally exhausting air in the box by using axial fans 70 and 71 is provided only on a bottom side of the box 4. Liquid crystal panels 63R, 63G and 63B, which are held by the optical unit frame 50a, absorb the illumination light from the light source 66 and thus have different increased temperatures.

Abstract: An LED display apparatus capable of reliably preventing damage caused by static electricity without worsening the visual recognition, in which an the display surface of the LED display apparatus is mounted an electrically conductive plate having a thickness nearly equal to, or smaller than, the height of the light-emitting portions L in a direction Z perpendicular to the display surface and having holes 3a perforated at positions corresponding to the positions of the light-emitting portions L on the display surface. The electrically conductive plate 3 is grounded, and a current due to the electrostatic discharge flows from the electrically conductive plate 3 into ground.
