Title: Surface acoustic wave element
Inventor: ISE EIJI
IPC: H03H9/145
Filed: 1990-09-29
Abstract: PURPOSE:To prevent short-circuit between electrode fingers caused in the case of high frequency processing of the surface acoustic wave element and to cancel a reflecting wave in a transducer by adopting a structure such that a slot is provided to a piezoelectric substrate at an interval of 1/4 wavelength each and the electrode fingers are bridged over the slot. CONSTITUTION:A slot 2 if provided to a piezoelectric substrate 1 made of a piezoelectric material such as a crystal or a lithium tantalate at an interval of 1/4 wavelength each. Then an electrode finger 3 made of a metallic material such as aluminum is formed in the slot 2 and on the piezoelectric substrate 1. That is, at first a resist 10 is patterned onto the piezoelectric substrate 1. Then dry etching or wet etching is applied to etch a part without the resist to form the slot 2. Moreover, a resist 11 is formed on the piezoelectric substrate 1. Then electrode fingers 3,3' are formed by vapor-depositing or sputtering an electrode metal. Then the electrode is formed by removing the resist 11. A reflecting wave is caused at an edge of the electrode finger 3 on the piezoelectric substrate 1 and an edge of the slot 2. However, since the phases of the reflecting waves are deviated by l80 deg., they are canceled together and no effect is caused on the traveling wave.

IPC: F21V7/00
Filed: 1990-09-29
Abstract: PURPOSE:To obtain a lightweight lighting device which can be easily shifted and transported and whose illumination efficiency is high by forming cases of synthetic resin, and connecting the cases together in such a manner that the cases can be opened and closed, and also disposing in each case a plurality of mirrors formed by lightweight material and a plurality of light sources. CONSTITUTION:One side of a case portion 1 is connected to that of another case portion 2 and the case portions 1, 2 made in a pair and each formed of FRP into the shape of a hollow parallelepiped are folded in two in such a manner that the case portions 1, 2 can be opened and closed via a hinge 3. Four round holes 6 are formed through a front panel 5 and a light source 7 and a mirror 8 are provided on a concentric circle. A halogen lamp equipped with an infrared reflecting film is used as the light source 7 so that reflection of heat rays onto the mirror 8 is decreased. A light-selecting multilayer film 20 is formed on the surface of the mirror 8 and heating of a subject for irradiation is prevented because the film 20 does not reflect infrared rays. Reduction of the weight of the lighting device can thus be achieved whereby the lighting device can be easily shifted and transported.

Title: Jig for heat treating furnace
Inventor: HIRAOKA TOSHIJI
IPC: C23C16/26
Filed: 1998-09-17
Abstract: PROBLEM TO BE SOLVED: To reduce a specific surface area of the surface, reduce the water- adsorption at the preservation time and retard the reaction with a mold-releasing agent by forming the jig out of a carbon fiber-reinforced carbon composite material, and impregnating and coating a thermally degraded carbon. SOLUTION: The impregnation and coating of the surface of the carbon fiber-reinforced carbon composite material with the thermally degraded carbon is preferably carried out by a CVI method or a CVI+CVD method. As the result, the open pores from the surface to the interior are impregnated and coated with the thermally degraded carbon to compact the composite material and to decrease the specific pore surface area on the surface. As the result, the composite material becomes the one having >=1.6 g/cm3 bulk density and <=4.5 g/m2 specific surface area, and the amounts of water and impurities adsorbed during a cooling period and preservation is decreased.  The reduction of the surface area and the decrease of the amount of the impurities regulated so as to be <=20 ppm are preferable because the reaction between the composite material and a mold releasing material comprising an metal oxide, a magnetic material, an electronic ceramic or the like is started from and accelerated by the impurities.
