Title: Method for heating hot sheet bar
Inventor: KAWASE TAKASHI
IPC: B21B45/00
Filed: 1988-06-24
Abstract: PURPOSE:To prevent generation of material defects in ends in the length direction of a sheet bar by stopping transfer of the bar or reducing a transfer speed of the bar in a heating zone and shifting an induction furnace in the width direction of the bar. CONSTITUTION:At the time when the top of a sheet bar 3 arrives at a top end detector 25, the detector 25 outputs a theoretical value signal showing arrival of the top of the bar 3 to a controller 21. Then, a temp. sensor 26 starts temp. detection to detect a temp. of the top of the bar 3 and sends the detection signal to a controller 21. Next, the controller 21 calculates a difference between the measured top end temp. of the bar 3 and a target temp. and controls outputs of a high frequency power source 27 based on a detected speed value of the bar 3 detected by a speed detector 24. An induction heat oil is shifted with an approach limit distance of the coil kept. As the result, the top of the bar 3 over the entire area in the width direction is heated by the induction heating coil and temp. drop in the top end is compensated.

Title: Method of post-treating extraction residue of refinement of phosphoric acid
Inventor: GIYUNTAA SHINMERU
IPC: C01B25/46
Filed: 1982-09-10
Abstract: The disclosure relates to a process for after-treating extraction residues, termed raffinates, originating from the extractive decontamination of crude phosphoric acid. To this end, the disclosure provides for the raffinates to be converted to two separate solid matter fractions of differant chemical composition by admixing the raffinates with a calcium compound so as to establish a pH-value of 1.2 up to 2.5. Next, the resulting precipitate consisting essentially of gypsum is filtered off as a first solid matter fraction, and washed with water. The resulting filtrate and the wash water are made into a mixture and predetermined proportions of calcium compound are added so as to obtain, after complete reaction, a fully reacted filter cake with a pH-value of 9 up to 12, the resulting suspension being filtered off at a pH-value of 6 to 8. The filter cake consisting essentially of calcium phosphate is separated as the second solid matter fraction, and allowed to react completely.

Filed: 1977-12-28
Abstract: PURPOSE: To provide an amorphous alloy having high hardness, superior wear resistance and high permeability over a wide compsn. range, and consisting of Co and/or Fe, Nb, Ni and B or B+Si.  
     CONSTITUTION: The amorphous alloy is represented by the following structural formula: (T 1-x-y Nb x Ni y ) 1-z X z  [where T is Co and/or Fe, X is B or B+Si (Si ≤ 25 atomic %), x=0.005 W 0.1, y=0.005 W 0.3 and z=0.015 W0.35]. In case of T=Co+Fe, the Fe content is 4 W 15 atomic % of the total amt. of (Co+Fe+Nb+ Ni). Since Nb and Ni are contained at the same time, superior mechanical and magnetic characteristics are exhibited over a wide compsn. range. The permeability is hardly lowered by heat treatment up to about 200°C in an assembling process, and hence the alloy is used in a magnetic device such as magnetic head.

Title: Rotary valve system cylinder head
Inventor: SAKAGUCHI FUMIO
IPC: F01L7/02
Filed: 1982-09-08
Abstract: PURPOSE:To simplify construction and enhance intake and exhaust efficiencies, by a rotary valve system cylinder head wherein a valve mechanism is changed from one for vertical motion to one for rotating motion. CONSTITUTION:In an intake stroke, only an intake valve 1 is opened, a piston is moved downward, and a fuel-air mixture is sucked in through the valve 1 by a negative pressure. In a compression stroke, both the intake valve 1 and an exhaust valve 2 are closed, and the piston is moved upward to compress the mixture. Then, in an expansion stroke, the mixture is ignited to explode by an ignition plug, and the piston is moved downward by the explosion pressure. In an exhaust stroke, only the exhaust valve 2 is opened, and the piston is moved upward to exhaust a combustion gas through the valve 2. Accordingly, cam shafts, valve springs and other component parts conventioally used to operate the valves are unrequired, the construction of the cylinder head can be simplified, and maintenance for valve clearrances or the like is unnecessitated. Since the number of component parts is small, weight and size can be reduced, so that cost can be reduced. In addition, since the openings (a), (b) of the combustion chamber can be formed in a rectangular shape, the intake and exhaust efficiencies are enhanced.
