Abstract: PURPOSE: To obtain a fire grate easy to supply and capable of standing against an usage under a severe condition during a long period of time by securing a refractory material to a shape reinforcing member.  
     CONSTITUTION: A Y-shaped anchor metal 2 is welded to an internal surface of a steel channel or a light-weight steel chnnel 3 with proper intervals and a mold is attached thereabove, then, shapeless rfractory material 1, mixed with water or other binder, is poured into the mold and is solidified, thereafter, the working mold is removed to form a fire grate A having a desired sectional configuration integrally. An upper surface a of the fire grate A is wider than a width of the steel channel 3 and has a constant thickness while this portion is connected to the steel channel 3 with a portion inclined toward outside. An outside portion of the steel channel 3 will not be affected so much by an effect of heat above the fire grate due to the existing of the portion a and remained ash on the fire grate A arranged in parallel with a proper interval will not be accumulated and drops, therefore, ventilation of air in a combustion chamber can be smoothed.

IPC: F02P19/02
Filed: 1981-06-30
Abstract: PURPOSE:To eliminate the inconvenience due to the thermal stress by connecting the voltage drop resistor directly to the heating coil through a switching means when the temperature of the glow plug is reached to the preset level prior to reaching to the setting of the preheating. CONSTITUTION:Upon closing of a key switch 2 to start the super-quick heating of a glow plug 1 through a relay contact rl1, the resistance of the heating coil Rg will increase gradually to unbalance the bridge circuit thus to increase the voltage across the terminals (a), (b). When the temperature of the glow plug 1 will reach to the setting level TM, the relay drive circuit 5 is functioned by a comparator (c) to open the contact rl1. At the same time the timer 6 is set to close the relay contact rl2 for the predetermined time to insert the voltage drop resistance R3 in series thus to decrease the current application. Said resistor R3 is made of a heating element and fixed to the silicon block where the temperature will vary similarly with the glow plug 1.

Title: Sliding contact material
Inventor: TAKIGUCHI FUJIMATSU
IPC: H01H1/023
Filed: 1983-06-08
Abstract: PURPOSE:To improve the wear resistance of a conventional sliding contact material consisting of Pt, Pd, Ag and Cu by adding specified amounts of In and one or more among Si, Zr, Bi, Ge and Ga to the contact material. CONSTITUTION:An alloy material having a composition consisting of, by weight, 0.1-1% Pt, 42-44% Pd, 39-41% Ag and 15.5-17.5% Cu has been widely used up to now as a sliding contact material, especially as a material for a brush contact. A brush contact of the alloy material shows, however, inferior wear resistance during sliding along a commutator and causes the generation of noise. In order to improve the wear resistance, 1-10% In and 0.5-3% one or more among Si, Zr, Bi, Ge and Ga are added to the alloy materal without changing the ratio in the composition. 0.01-0.5% Fe group metal may be further added.

IPC: C22C33/04
Filed: 1979-08-13
Abstract: PURPOSE: To provide a MoO 3  briquette being used in adding Mo to steel in a good adding yield by using an organic binder to bind a mixture consisting of powdered MoO 3  and a reducing agent of Fe-Si particles.  
     CONSTITUTION: MoO 3  powder and a reducing agent of Fe-Si less than 2mm in size are mixed to form Si/Mo ratio between 0.45 and 0.65. The mixture is mixed with an organic binder such as waste pulp liquid or molasses, is formed into brickette of a specified form, and then dried. The briquette is added to molten steel so that MoO 3  is reduced to MoO by Fe-Si and alloyed into molten steel. MoO 3  is very easy to reduce and therefore is easily reduced by Fe-Si in a short period time. Said procedure prevents loss in the form of MoO 3  having a high vapor pressure so as to effect a high yield alloying in steel.

Abstract: PURPOSE:To improve the antitumor activity, by treating an aqueous solution of the product, which has been obtained by purifying the extract of neem bark extracted with hot water, with molecular sieves and subjecting it to a specific treatment. CONSTITUTION:The extract of neem bark extracted with hot water is purified by the alcohol precipitation method or diaphragm membrane method to obtain an aqueous solution of the purified matter. The aqueous solution is treated with molecular sieves having a fractionation molecular weight of from 1X10<3>-1X10<5> to 1X10<3>-2X10<5> to obtain three polysaccharide fractions. The polysaccharide obtained from the first fraction of the three fractions is dissolved in water and hydrolyzed with alpha-amylase and the digested materials are removed to obtain a non-digested polysaccharide. The non-digested polysaccharide is subjected to a treatment with molecular sieves having a fractionation molecular weight of 1X10<3>-2X10<5>. A quaternary amine saccharide precipitating agent is added to the liquid which has been passed through them to remove said saccharides, thereby obtaining neutral saccharides. Then, an aqueous solution of boric acid is added to the resulting neutral saccharides so that the pH may be brought to 8-9, thereby producing a precipitate. The boric acid is removed from the precipitate, and the precipitate is dissolved in water. The solution is treated with molecular sieves having a fractionation molecular weight of 2X10<3>-3X10<5> to obtain three polysaccharide fractions. From the three fractions, polysaccharides CSP-I, CSP-II and CSP-III are obtained, respectively.
