Title: Hot-water supplier
Inventor: AKAGI ISANORI
IPC: F24H1/44
Filed: 1979-12-27
Abstract: PURPOSE: To obtain a compact hot-water supplier by narrowing the distance between the burner and the body to be heated.  
     CONSTITUTION: The lids 8a and 8b are fitted with the upper and the lower openings of a prismatic wire net 7, of which outside is provided with the heat resisting and heat insulating material 9 consisting of the blanketlike ceramic fiber with some thickness. Besides, said heat-insulating material 9 is covered by a comparatively thin, heat resisting, porous material 10 which forms a combustion surface 6a by piling up the glass fiber woven into cloth. In this constitution, the fuel gas from the wire net 7 is led to pass through many zigzag passages of small diameter of the above-mentioned heat-insurating material 9 to flow to the side of the above-mentioned porous material 10, and is burned on the combustion surface 6a. By this method, good and stable combustion can be performed even in the case that the combustion surface 6a is positioned very near to the body 2 to be heated.

Inventor: ISHIDA HIROYUKI
IPC: F02M43/00
Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To prevent self-ignition of fuel injected in advance to ensure combustion. SOLUTION: When a piston 2 starts rising from the position of -180 deg. (a bottom dead center), a 95% of fuel is injected from a main fuel injection nozzle 5 to form pre-mixture of the fuel and air 10, (A). At a time point where the piston rises to the position of -90 deg., water is injected from a water injection valve 6 for a predetermined period to cool the pre-mixture and to stir mixture. Accordingly, growth of nucleus that is subject to the self-ignition is prevented thereby to prevent the self-ignition (B). When the piston 2 rises to the position of 0 deg.

IPC: C03C25/10
Filed: 1998-06-04
Abstract: PROBLEM TO BE SOLVED: To inhibit glass fibers from occurring fluffs by using starch as a main coating layer-forming agent and a poly(ethylene oxide) with a specific value of the weight-average molecular weight in the glass fiber sizing agent. SOLUTION: The weight-average molecular weight of the poly(ethylene oxide) included in the sizing agent is adjusted to >=10,000.
