Title: Dielectric substrate with radiation board
Inventor: SUZAKI HIDESHI
IPC: H01L25/065
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To provide a dielectric substrate with radiation board whose size can be reduced. SOLUTION: A groove 12 is formed on the surface of a dielectric substrate 1, and a radiation board 3 is inserted into the groove 12, and then, a heating element 5 is mounted on the surface of the board 3. An end part 16 of the radiation board 3 protrudes from both end sides of the dielectric substrate 1, bent toward outside in parallel to the rear surface of the dielectric substrate 1, and the rear surface of a parallel bent 17 is flush with the rear surface of the dielectric substrate 1. The built-up heat of the heating element 5 is transferred to the radiation board 3 and then is released outside the dielectric substrate with radiation board from the parallel bent part 17.  The width of the radiation board 3 (groove 12) can be very narrow, to that of the heating element 5, so that an occupation area of the radiation board 3 occupying on the surface of the dielectric substrate 1 can be made narrow. Thus, a circuit pattern formation area formed on the dielectric substrate 1 is enlarged, so that the dielectric substrate with radiator board can be reduced in size by that amount expanded.

IPC: H04R1/02
Filed: 1989-10-17
Abstract: PURPOSE:To enable a sound to be listened while attaching a surrounding effect by using a chair with built-in speakers by attaching right and left speakers at the right and left sides of a head rest part, providing right and left reflecting plates while keeping a prescribed gap with the right and left speakers, and enabling the sound from forward and backward sides to pass the gap between the speakers and the reflecting plates. CONSTITUTION:For example, the right and left speakers 16, 17 attached to the right and left sides 13a, 13b of the head rest part 13 are designated as the speakers for surrounding. Therefore, the sound from the speakers 16, 17 are reflected on the reflecting plates 14,15 and arrive at persons being scattered and surrounding them, which realizes reproduction with the surrounding effect, and also, the sound from a main speaker from the front side can pass through to the backward side without being reflected at both sides of the head of the persons seated. Thereby, it is possible to perform stereo reproduction with a satisfactory surrounding effect without disturbing the sound field of the stereo reproduction.
