Abstract: PURPOSE: To obtain mullite useful as refractory starting material or an Al alloy, high molar ratio sodium silicate and a high alumina material by adding a specified amount of an NaOH soln. to calcined and pulverized clays followed by pressurization.  
     CONSTITUTION: Clays such as kaolinite and halloysite or clays-contg. starting material such as diaspore, white bauxite or aluminous shale is calcined at 1,000W 1,300°C and pulverized, and an NaOH soln. of ≥30% concn. is added so that the ratio of SiO 2 :Na 2 O is adjusted to 2:1 or more, preferably about 3 to about 2/3 of silicic acid contained. The soln.-added pulverized material is then pressurized at ≥130°C in an autoclave and filtered to obtain molar ratio sodium silicate having an SiO 2 /Na 2 O molar ratio of ≥2 or about 3 as well as muillite (3Al 2 O 3 .2SiO 2 ) or a mullite-contg. high alumina material as the residue.

Title: Combustion chamber structure of engine
Inventor: MARUHARA MASASHI
IPC: F02B23/08
Filed: 1983-07-07
Abstract: PURPOSE:To prevent the occurrence of knocking as well as to improve a degree of charging efficiency, by forming a guide wall situated more downward than a head part of a suction valve in time of maximum lifting, into a state of being substantially tilted. CONSTITUTION:A guide wall 7, directing suction air to a specified direction, is installed in position along a part of the circumference of a suction valve seat 5. At the guide wall 7, a lower side wall 7a situated more downward than a heat part 6a of a suction valve 6 in time of maximum lifting becomes a curved surface form being substantially tilted against an upper side wall 7b rising steeply. Thus, with the formation of a swirl, the occurrence of knocking is preventable and, what is more, especially in time of high load driving, suction resistance is reduced to some extent whereby a degree of charging efficiency can be well heightened.

Title: Electrically conductive elastic cable conductor
Inventor: ASAI MASATO
IPC: H01B1/02
Filed: 1989-05-18
Abstract: PURPOSE:To obtain the title conductor of great tensile strength sufficient to stand such stresses as flexure, torsion, tension, etc. by forming an alloy which contains 0.25 to 10wt.% of Cr and yet 0.001 to 3.0wt.% in the aggregate of Sn, Zr, Mg, Mn, Zn, etc., and which has the rest of contained elements, namely, Cu and P having its content restricted to less than 100ppm. CONSTITUTION:Cr grains drawn in the processing direction thereof are dispersedly arranged respectively in the base material of a conductor in the processing direction so as to raise the elasticity of the base material at a jump. P content exceeding 100 ppm of the base material causes the formation of an intermetallic compound consisting of Cr and P for decreasing the number of the Cr grains being drawn and for readily coarsening them to have a bad influence on the elasticity. The purpose of adding a group of specified elements including Sn to the base material is to improve strength, flexibility, heat resistance, etc. without having an influence on the act of drawing the Cr grains as the result of fusing Cr in a Cu radical and forming a Cr compound with Cu alone. Thus, the conductor being excellent in strength, conductivity and elasticity can be obtained at low cost.

Filed: 1986-05-30
Abstract: PURPOSE:To eliminate each dial operation by recording magnetically an identification code and an originating telephone number to a telephone card and performing an outgoing operation via a telephone set available with said telephone card. CONSTITUTION:A card identification code deciding part 8 switches the input of an originating number transmitting part 12 to an originating telephone number memory part 10 via a control part 13 after deciding an automatic dial card for gift, etc. Then the part 8 transmits the originating telephone number of a specific telephone card 6 stored in the part 10 with no dial operation. Therefore no reaction is obtained despite the operation of push-buttons or a rotary dial part 11. In a busy mode a calling frequency count/write part 9 counts down the calling frequency in response to the call time and writes the calling frequency measured when the call is through to the calling frequency part 3 of a specific card to finish a series of actions.
