Title: Removal of oxygen
Inventor: TAMAURA YUTAKA
IPC: B01D53/46
Filed: 1990-04-04
Abstract: PURPOSE:To remove oxygen and to reduce a product to the original iron oxide or ferrite by the soot in gas by subjecting the gas containing oxygen and soot to the catalytic reaction with iron oxide or ferrite. CONSTITUTION:When the exhaust gas high in oxygen content from a diesel engine is treated, the temp. of a reaction chamber 1 having iron oxide such as magnetite or ferrite received therein is heated to predetermined temp. of about 200-400 deg.C, pref., about 30 deg.C to send the exhaust gas containing oxygen and soot into the reaction chamber 1. Whereupon, oxygen is reacted with magnetite to form maghemite and oxygen can be removed.

Title: Fluid velocity reducing pipe
Inventor: ISHIYAMA TETSUO
IPC: F16L41/02
Filed: 1990-04-04
Abstract: PURPOSE:To obviates a vent pipe by bending a pipe, which reduces the velocity of water therein, to give said pipe a displacement larger than a predetermined multiple of the pipe diameter so that the quantity of air included in the water is reduced due to the decrease of the velocity of the water. CONSTITUTION:A bent pipe 2 of polyvinyl chloride of nominal diameter 100 is bonded to an expansion joint 1 of polyvinyl chloride of nominal diameter 100 and an noncombustible material layer 3 composed of heat resistant hydraulic setting inorganic material is formed over the outer circumferential surface of the pipe 2 excluding the surface of the lower connecting part thereof and the layer 3 is heated to be cured. The curvature of the pipe 2 is such that the ratio of the displacement of bending B to the inner diameter A of the pipe, i.e. B/A X 100%, is at least more than 40%. The velocity of the water vertically flowing down is reduced by the bent section of the pipe, causing the quantity and the velocity of the air included in the water and flowing down to be reduced, and reducing thereby the fluctuation of the pressure of the air in the pipe. Consequently, the water seal of a trap is prevented from being broken and the need for a vent pipe is avoided.

Title: Illumination globe and method for forming light diffusion film
Inventor: SANO KAZUHIRO
IPC: F21V3/04
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a uniform paint film and prevent the yellowing of the film by ultraviolet rays by applying and drying a suspension mixed with a white pigment, a water-soluble polymer resin, a polycarboxylic acid salt dispersing agent, and a silane coupling agent having the epoxy group on the inner face of a glass globe to form a light diffusion film. SOLUTION: A suspension added with a silane coupling agent having the epoxy group to a solution suspended with a white pigment, a water-soluble polymer resin, and a polycarboxylic acid salt dispersing agent is used for forming a light diffusion film, and it is applied and dried on the inner face of a glass globe to form the light diffusion film. The yellowing of the light diffusion film by the radiation of ultraviolet rays is remarkably suppressed and the water resistance of a paint film is increased due to the existence of the silane coupling agent having the epoxy group in spite of the use of the polycarboxylic acid salt dispersing agent. Since the polycarboxylic acid salt dispersing agent is added to the water-soluble polymer resin and white pigment, the light diffusion film is uniformly finished with no irregularity.

Abstract: PROBLEM TO BE SOLVED: To provide a radar apparatus, which can remove the influence of a low-frequency noise in a mixer for a high frequency without largely attenuating a high-frequency signal, and whose detecting sensitivity can be enhanced. SOLUTION: An amplitude modulator 18 which amplitude-modulates a transmitting signal Ss at a determined modulation index (m) [where 0<m<1] according to a modulation signal Mb supplied from a sine-wave oscillator 20 via a modulation-intensity regulator 19 is provided between a distributor 16 by which a high-frequency signal, in a milliwave band generated in a voltage- controlled oscillator, is power-distributed into the transmitting signal Ss, a local signal L and a transmitting antenna 22.

Filed: 1989-04-11
Abstract: PURPOSE:To measure the movement distance of a body which passes at right angles to the irradiation direction of a laser beam with high accuracy without touching the body by converting scattered light from the body into an electric signal. CONSTITUTION:The irradiating laser light from a laser light source 1 is split by a beam splitter 2 and one laser beam is shifted in frequency by Bragg cells 3 and 4. Then the 1st and 2nd laser beams irradiate one point by an optical means, so interference fringes are formed to obtain the scattered light. This scattered light is converged and converted 17 photoelectrically to obtain a signal of frequency corresponding to the moving speed of the interference fringes and the conveyance speed of the body. A driving frequency detecting means detects the frequency difference between the laser beams to generate a reference signal and the photoelectric conversion output is supplied to 1st and 2nd change point detecting circuits of a frequency difference detecting circuit 20 as a signal corresponding to the movement distance of the body. Then the movement distance of the body can be measured according to output pulses of the detecting circuit 20.
