Title: Heater sheet and heater system using it
Inventor: KOIDE YOSHIHIRO
IPC: H05B3/20
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To provide a heater system for enhancing the usefulness in performing efficient heating. SOLUTION: A heater sheet is a sheet formed by weaving weft and warp threads, and is composed of a portion fabricated of the weft and warp threads, and a clearance portion defined by the weft and warp threads. The warp thread is made of cotton yarn 2 of insulative material, and a part of the weft thread is made of copper wire 3 as conductive wire. When a current is supplied to the copper wire 3, the cotton yarn 2 of insulative material serves as a resistor to generate heat, and to radiate heat from a sheet surface. Since a sheet-like heater element is used, it is easily treated as in the case of cloths and has a good heat radiation effect for light weight. By changing the way of knitting and per unit area carbon particles applied to the cotton yarn 2, resistance is made variable and can be changed to a desired heating.  This can heat a small- size space at the foot with high efficiency by radiating radiation heat from the surface.

Inventor: WATKINS WILLIAM LEWIS HENDERSO
IPC: B01D53/86
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To increase resistance to poisoning by a sulfur in waste gas of an internal combustion engine by forming a NOx trap from a specified wt.% platinum and sodium. potassium or their mixture with a significantly many sodium or potassium incorporated more than conventional amount. SOLUTION: The NOx trap for the waste gas of the internal combustion engine is constituted by incorporating a porous supporting body impregnated with an alkali metal selected among sodium, potassium and their mixture and platinum. A thin coated film such as alumina is applied on a substrate, and after drying and burning the film, each catalyst of sodium or potassium and platinum is stuck and charged by an impregnating method, etc., on the coated film by at least 30wt.% alkali metal and 0.2-4wt.% platinum to porous supporting body weight, and the NOx trap is obtained by drying and burning the material in air. In such a way, the poisoning due to the sulfur is markedly overcome, and a NOx capturing efficiency of this catalyst is maintained.

Inventor: KASHIWADA TAKESHI
IPC: F28C1/14
Filed: 1988-02-05
Abstract: PURPOSE:To enable air infiltrated into the title heat exchange body to be smoothly released by a method wherein the heat exchange body is formed into a flat and thin hollow body as a whole, the most part of the width of a liquid flowing-down passage is formed into a slow flow part for flowing-down liquid, and baffle seal members with a horizontally long length are distributed in layers, their position being shifted alternately to form a zigzag flow path. CONSTITUTION:Cooling water which has flowed in through a supply port 11 flows down successively through the inside of a zigzag flow path 23 formed in sequence between baffle seal members 22, and contacts each of wall plates 14 and 15, being sufficiently agitated. With the aid of these wall plates, the cooling water exchanges heat with air flowing in a horizontal direction through each of air flow passages. The air remaining in a slow flow part 24 of flowing-down liquid is pushed toward the upper corner part of the folded path 24a of the slow flow part 24 for flowing-down liquid in accordance with the movement of the cooling water whose level is a little raised by a ridge 80, and tends to stay at the upper corner part. However, the air streams into an overflow path 25 through an air release hole 60 and is lifted through the overflow path 25 to be discharged from the supply part 11 to the external side.

Title: Intake manifold and manufacture thereof
Inventor: YOSHIDA TAKAYUKI
IPC: F02M35/10
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To provide an intake manifold and a manufacturing method thereof, which enables the improvement of part precision and reduction in cost. SOLUTION: An intake manifold 1 is constructed of a surge tank 2, a port part mounting flange 3, four pipes 4a, 4b, 4c, 4d, and a throttle body mounting flange 5. In the intake manifold 1, partial welding along the circumference direction is carried out in the connection part for each component, so that basic connection strength can be secured, while in the unwelded part in the connection part, coating based on a resin material such as 11-nylon is applied, so that a seal between the partial welding parts in the circumference direction can be secured. In this way, the intake manifold, which is exposed to a high temperature if brazing is used for connecting components together, is prevented from exposure to a high temperature, so that deformation in each component because of temperature distortion is hardly generated. Consequently, assembly can be carried out with high precision.
