Abstract: PROBLEM TO BE SOLVED: To provide an ALC panel production process which enables inhibition of retardation of the dissolution of a siliceous material in the autoclave curing by allowing a C-S-H(calcium silicate hydrate) gel necessary as a precursor of tobermorite to exist in a reaction system in such a state that the C-S-H gel is not deposited on the surface of the siliceous material, through modification of the cement feeding method in the formation of a raw material slurry. SOLUTION: The production process comprises: using a powdery siliceous raw material(s), a powdery calcareous raw material(s) and a powdery process recycle feedstock as main raw materials; adding powdery aluminum, an additive(s) and water to the main raw materials, to mix them together and to form a slurry; casting the slurry into a frame mold in which reinforcing bars are set, and foaming the cast slurry; hardening the foamed slurry for a specified period of time to form a semi-plastic formed body; withdrawing the semi-plastic formed body from the frame mold; cutting the semi-plastic formed body into prescribed dimensions; and placing the cut body in an autoclave to subject the cut body to steam curing at a high temperature under a high pressure, to produce the objective ALC panels;  wherein, water is added beforehand to cement used as one of the calcareous raw materials, in a 50-200 vol.% ratio of water to the volume of the cement and then, they are agitated for 0.5-120 min and thereafter, the agitated mixture is mixed with the other raw materials to form the slurry.

Abstract: PURPOSE:To work work pieces at high efficiency, by preventing the lowering of working velocity by controlling dividing a suspension period that an element mounted to a charging circuit of a condenser is in OFF into three kinds. CONSTITUTION:A suspension period that a switching element 16 installed to a charging circuit of a condenser 18 is in OFF is controlled dividing it into three kinds of a suspension period of a period that the condenser is charged, a suspension period just after electricity is discharged to a conduction working void from the condenser 18 and a period that the condenser 18 is not charged and currents are directly supplied to the conduction working void. Quiescent time for deionizing the working void just after electricity is discharged to the working void from the condenser 18, quiescent time for controlling mean working currents in case of normality and mean working currents for eliminating a condition that interpolar impedance lowers and is brought to a false short-circuit condition can be set in the optimum condition each and separately.

Title: Low fluid resistance metallic material
Inventor: ONDA TOMOHIKO
IPC: C23C26/00
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To drastically lower the friction resistance that a metallic surface receives from liquid by coating the metallic surface, which has a fine rugged structure on the surface and has a contact angle with water of a specific value, with a liquid repulsive material. SOLUTION: The surface of a metallic material having the contact angle with water of <=30 deg. is provided with the rugged structure having a height of <=300μm. The actual surface area per 1cm<2> in plane view is specified to >=3 to <=20cm<2> . The contact area when a smooth rigid body on the surface of the rugged structure is specified to <=0.2cm<2> per 1cm<2> rigid body surface. The metallic surface coated with the liquid repulsive material has the contact angle with liquid larger than 90 deg.. An air layer is formed between the metallic surface and the liquid on account of the high liquid repulsive property of the metallic surface. Then, the metallic surface directly receives the friction resistance by air. Since the viscosity of the air is much smaller than that of the liquid, the friction resistance that the metallic surface receives is lowered.

Title: Manufacture of thin-film thermistor
Inventor: NAGAI TAKESHI
IPC: H01C7/04
Filed: 1989-04-17
Abstract: PURPOSE:To reduce condensation of Au-Pt electrode film and to improve thermal stability at the contact part between an SiC thin film and the Au-Pt electrode film by using the Au-Pt electrode film where the mixture of a Ca oxide and a Ti oxide is added slightly. CONSTITUTION:A pair of Au-Pt calcination electrode film 22 of a specified shape and an SiC sputter resistance thin film 23 are formed on an insulation substrate 21 and a small amount of a mixed oxide of a Ca oxide and a Ti oxide is added into this Au-Pt calcination electrode film 22 slightly. When the Au-Pt calcination electrode film 22 including a small amount of oxide is used, it becomes difficult for condensation even at a high temperature of 500 deg.C to proceed. Thus, it becomes possible to obtain a practical SiC thin film thermistor 1 which can operate for a long time even at a high temperature of 500 deg.C.

This steel sheet can be suitably used for production of a two-piece vessel by being subjected to drawing and ironing or stretching. In this Ti-added extra low carbon steel, the occurrence of heat buckle can be prevented even in the case of low-temp. annealing owing to the limitation of the ratio between N in AlN and N in the steel, and also wrinking at the time of necking can be prevented. This steel sheet can be obtained by casting a steel slab of prescribed composition and regulating the heating temp. in its hot rolling to <=1000 deg.C.
