Title: Gas boiler with incomplete combustion preventer
Inventor: KODAMA MASARU
IPC: F23N5/24
Filed: 1995-01-11
Abstract: PURPOSE: To easily prevent the overheating and discoloring of a front cover even when a high temperature combustion exhaust gas spouts out of an open window provided oh a mounting base fixed on a side wall of a combustion chamber of a boiler with an incomplete combustion preventer having a secondary thermocouple. CONSTITUTION: A part is cut out of a side wall 31a forming a combustion chamber and erected to integrally form a heat shielding cover 31c covering an open window 15a facing a thermal part 11a of a secondary thermocouple 11. Thus, heat is diffused once hitting the heat shielding cover 31c, even when a high temperature combustion exhaust gas spouts out of the open window 15a.

Title: Production of fiber-reinforced resin part
Inventor: AIHARA MICHITAKA
IPC: C08G59/00
Filed: 1990-01-30
Abstract: PURPOSE:To enable a large fiber-reinforced resin part to be produced without using a metal mold by impregnating a fibrous reinforcement with a specific liq., highly elastic epoxy resin and molding the impregnated reinforcement under a specified pressure at a specified temp. using a mold. CONSTITUTION:A fibrous reinforcement is impregnated with a liq., highly elastic epoxy resin comprising a mixture of a minor amt. of a high-mol.-wt. epoxy resin with a major amt. of a low-mol.-wt. epoxy resin. The impregnated reinforcement is molded in a mold under 30-40kgf/cm<2> pressure at 100-120 deg.C to give the desired fiber-reinforced resin part. If the epoxy resin contains a resin with (n) in the formula equal to or lower than 0.5 in an amt. of at least 40 times the amt. of the resin with (n) equal to or higher than 2, the impact resistance of the resulting resin part is effectively improved. The addition of a small amt. of a hydroxylic ceramic, such as one represented by Al(OH)3, to the resin mixture improves the heat resistance and the incorporation of a magnesium alloy fiber into the reinforcement gives high strengths.

Title: Photosensor
Inventor: SHIMIZU MANABU
IPC: H01L31/12
Filed: 1990-01-31
Abstract: PURPOSE:To surely detect a body to be detected in the same manner as a blank having a light-shielding property such as a sheet of paper or the like even in the case of a transparent body such as a transparent sheet or the like by a method wherein two polarization plates are installed in a light path so as to keep an interval where the body to be detected is marched in the middle. CONSTITUTION:When a body 20 to be detected is a transparent body of a non-isotropic material, linearly polarized light which has passed a first polarization plate 12 is rotated optically by a birefringence phenomenon when it is transmitted through the body 20 to be detected, and has a light-wave component parallel to the polarization direction of a second polarization plate 14. Consequently, the body 20 to be detected is situated in the middle between the first polarization plate 12 and the second polarization plate 14, light waves are passed through the second polarization plate 14, an optical signal is detected by a photodetection part 16 and the existence of the body 20 to be detected is detected. Although the optical rotation degree of the body 20 to be detected is changed by the property of a refractive index of the body 20 to be detected and by the thickness of the body 20 to be detected, the light-wave component which passes the second polarization plate 14 is formed when the object 20 to be detected is formed of the non-isotropic material. Thereby, an optical signal can be detected.

Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To inexpensively, easily and artificially produce a gem stone having desired color and surface brightness by, if necessary, pulverizing an inorganic raw material such as an inorganic waste material or the like, then molding, drying the green body to have an appropriate water content, grazing on a portion or the whose of the surface of the green body and firing the green body. SOLUTION: An inorganic raw material is molded by slip casting, extruding or further repressing or the like and dried to have an appropriate water content. Though clay, feldspar or the like can be used as the inorganic raw material, it is economically advantageous to use, as a portion or whole of the inorganic raw material, waste inorganic materials, e.g. wastes from a pottery production plant, glass waste materials, incinerated ash of dirty mud from sewerage or the like. The inorganic raw material is crushed as occasion demands or finely ground using a mill and mixed to obtain a desired composition. Almost whole surface of thus obtained green body is grazed using a desired graze, and the grazed green body is charged into a roller hearth kiln or the like and fired to obtain a colorful artificial gem stone.
