Title: Method for manufacturing titanium dioxide
Inventor: YOOZEFU AUAA
IPC: C01G23/053
Filed: 1988-11-22
Abstract: For the preparation of titanium dioxide by the sulphate process, titanium slag and ilmenite are used as starting materials and are digested simultaneously but separately, i.e. different amounts of 98.5% strength and 85% strength sulphuric acid are added to them, the temperatures being slightly below the starting temperatures and the digestion reactions being initiated by adding a small amount of superheated steam. After the digestion, the two mother liquors are mixed and are processed together to give TiO2, the 23% strength dilute sulphuric acid obtained in the process being concentrated to about 85% with isolation of metal salts and being recycled. Highly concentrated sulphuric acid, preferably obtained by roasting the metal sulphates obtained in the process, is predominantly used for the titanium slag digestion, while the excess concentrated 85% strength sulphuric acid is used predominantly for the ilmenite digestion, so that the dilute sulphuric acid obtained can be virtually completely reused in an economical manner.

Title: Residual magnetism reducing method for deck plate
Inventor: NIINO TOSHIFUMI
IPC: E04B1/92
Filed: 1997-10-27
Abstract: PROBLEM TO BE SOLVED: To simply reduce the influence of residual magnetism on a deck plate. SOLUTION: A magnetization pattern of residual magnetism of a deck plate and the magnetic field distribution at a designated height are measured, and on the upper side of the deck plate, a steel material having N-pole and S-pole in the vertical direction is arranged in the direction of canceling the residual magnetism of the deck plate. Thus, the magnetic field by the residual magnetism is canceled by the magnetism of the steel material, so that the intensity of magnetic field at a designated height from the deck plate can be reduced.

Title: Rotating speed detector
Inventor: TERAMAE KATSUHIRO
IPC: G01P3/481
Filed: 1998-10-15
Abstract: PROBLEM TO BE SOLVED: To improve reliability in high temperature environment and simplify the constitution by preventing various problems caused when signal processing for frequency conversion is conducted by a microcomputer. SOLUTION: A comparator 5 compares with a d.c. signal input from a detection amplifier 4 with a designated threshold to output a square wave pulse signal corresponding to a projecting and recessed part 1a of a rotor 1 to a pulse converting circuit 6. The frequency of a pulse signal Va is once converted to a level of d.c. voltage Vc by a monostable circuit 7 of the pulse converting circuit 6 and an integrator 8 and then the level of the d.c. voltage Vc is converted to the frequency of a pulse signal Vd by a voltage control oscillator 9. Thus, the frequency of the pulse signal is converted without the microcomputer not to cause delay in signal processing, so that even in the case where the rotating speed changes within a short time, the change can be followed.  Furthermore, the operating current and the power consumption can be reduced so that the burden of a battery of an automobile can be lightened to improve reliability in high temperature environment and simplify the constitution.

Title: Production of sheet to be thermally transferred
Inventor: NAKAMOTO MITSUHARU
IPC: B41M5/52
Filed: 1993-10-29
Abstract: PURPOSE:To prevent blurring of image from being generated with the lapse of time after setting by specifying the weight of a solvent in a receptive layer when the base material is coated with composition for forming the receptive layer and dried to form the receptive layer in the case of producing a nonthermal transfer sheet used in combination with a thermal transfer sheet. CONSTITUTION:An image is formed by heating a thermal transfer sheet having a dye layer containing sublimable disperse dye by a thermal head and transferring die on the surface of a nonthermal transfer sheet 1. In a method for forming the image, the nonthermal transfer sheet is constituted by coating a sheetlike base material 2 with composition for forming a receptive layer in which resin for forming the respective layer is dissolved or dispersed in a solvent and drying the same to form the respective layer 3. In a drying stage of the receptive layer 3, it is so dried to remove the solvent that weight of the solvent in the respective layer is regulated to <=12% of weight of resin forming the respective layer. Thereby trouble is solved wherein diffusion is caused by the solvent remaining during preservation after setting and the image is blurred.

Title: Energy beam tube welding method and welding tube making device
Inventor: HAYASHI TOMOTAKA
IPC: B23K26/21
Filed: 1993-10-29
Abstract: PURPOSE:To make a tube by welding of thick thickness material having lower porosity due to the entrapment of shield gas by executing welding with giving ultrasonic vibration on the molten metal near key hole. CONSTITUTION:By bringing ultrasonic vibrators 5, 5 into contact with both edge parts of opened tube, ultrasonic vibration is given to the molten metal near a key hole 9. At welding a thick thickness, pulsating flow of a molten metal 8 is generated by repeating the piercing/closing of key hole 9, the pulsating wave entraps the shield gas near the key hole 9 into the molten metal 8. Thus, when ultrasonic wave is given to the molten metal 8 near the key hole 9, gas bubble violently repeats contraction/expansion due to ultrasonic wave, the gas bubble is stripped from solidifying boundary to be floated, the gas bubble is not entrapped in solidified metal. Accordingly, because the gas bubble itself has the power to be striped from solidifying boundary so as to float, the gas bubble is stably discharged to the outside of molten metal.

Title: Method for chilling cast iron member
Inventor: SUZUKI KOICHI
IPC: C21D5/00
Filed: 1989-11-15
Abstract: PURPOSE:To improve the thermal efficiency of a heater and to suppress the fluctuation in hardening depth by heating a cast iron member at a specific temp. to melt only the inside and rapidly cooling the cast iron member from this state. CONSTITUTION:The melting temp. of a decarburized layer 6 becomes T1 from a transformation curve (a) if the carbon content of a base material 7 is designated as C0 and the melting temp. as T0 and the carbon content of the decarburized layer 6 is assumed to be decreased to C1 by a decarburization treatment. This melting temp. T1 is then higher than the melting temp. T0 of the base material 7. The decarburized layer 6 does not melt and only the base material 7 melts if a cam 2 is thereafter heated by a high-frequency coil 5 at T2 lower than the melting temp. T1 of the decarburized layer 6 and higher than the melting temp. T0 of the base material 7. The decarburized layer 6 supports the base material 7 in the molten state and the cam 2 maintains its original shape accordingly without causing the collapse and deformation. The molten part under the surface layer of the cam 2 is chilled if the cam 2 is rapidly cooled from this state by blowing water to the surface thereof. The hardened layer consisting of the chill structure which is high in hardness and is highly resistant to wear is thus formed.

Abstract: PURPOSE:To obtain a battery which can be used repeatedly and continuously even after explosion preventing function is operated, by installing an elastic valve member to close a valve hole and pushing up the elastic valve member to discharge gas outside through the valve hole and gas vents when the inner pressure of the battery becomes higher than a prescribed value. CONSTITUTION:A battery is sealed by bonding a valve body 4 made of a metal plate from the inside face of a sealing plate lower case 3 by means of a resin adhesive 6 which is resistant against organic electrolyte and adhesive to metals. After that, a cap 5 which has a gas vent 5a in a projected part 5b and a cylindrical elastic body 7 made of styrene-butadiene rubber in the projected part 5b is put on and the opening edge part 3b of the sealing plate lower case 3 is bent and curved inward to seal and fix the battery. When the inner pressure of the battery rises and becomes equal to or more than a prescribed value, the metal valve body 4 is pushed up and the valve hole is opened and thus gas inside the battery can escape to outside. In this way, secular deterioration is lowered and the battery does not lose its function even after explosion preventing function is operated and the battery can be used continuously and repeatedly.
