Title: Laser-gas refresher for gas laser oscillator
Inventor: YAMAGUCHI YUTAKA
IPC: H01S3/036
Filed: 1987-12-17
Abstract: PURPOSE:To refresh a laser gas without interrupting gas laser oscillation by suspending the sealing operation of the laser gas and starting normal refresh operation when computed input output characteristics exceed deterioration limit reference characteristics and returning operation to sealing operation when characteristics are recovered to normal reference characteristics. CONSTITUTION:Discharge currents detected by a discharge input detector 6 and a laser output detected by a laser output detector 7 are input to a comparator 8, and input output characteristics are arithmetically operated by the comparator 8, and compared with proviously set reference characteristics, input output characteristics F1 in a normal laser gas and input output characteristics F2 at a deterioration limit. When the degree of deterioration of the laser gas exceeds the deterioration limit, sealing operation is stopped, the supply and exhaust of the laser gas are started, and the degraded laser gas is diluted gradually with the anew fed laser gas, and refreshed. An exhaust valve 5 is opened and closed through a controller 10 so that pressure in an oscillator detected by a pressure sensor 4 is brought to operating pressure at that time. When input output characteristics are recovered to a normal state, the supply and exhaust of the laser gas are stopped, and sealing operation is conducted again.

Title: Liquid information measuring device using sound wave
Inventor: SUGINO MASAYOSHI
IPC: G01F23/28
Filed: 1997-11-18
Abstract: PROBLEM TO BE SOLVED: To provide a liquid information measuring device designed to measure the liquid level and the propagation time of a sound wave by use of a single sound wave oscillating element which produces the sound wave. SOLUTION: An ultrasonic sensor S has an ultrasonic oscillating element 20 having a transmitting-receiving part 22 disposed in fuel and has reflectors 33, 34 disposed in the fuel. A reflector 35 reflects ultrasonic waves of mutually proximate frequencies transmitted from the ultrasonic oscillating element 20 and reflects the waves toward the ultrasonic oscillating element 20. The reflector 34 reflects toward the level of the fuel the ultrasonic waves transmitted from the ultrasonic oscillating element 20 and, when sound waves reflected from the level of the fuel impinge thereon, reflects the sound waves toward the transmitting-receiving part 22. A phase measuring apparatus 90 binarizes the received outputs derived from the reflected ultrasonic waves from the ultrasonic oscillating element 20, and calculates the phase difference between the binarized outputs.  A microcomputer 40 calculates the propagation time of the sound wave and the level of the fuel according to the phase difference and each of the frequencies.

IPC: C22B9/10
Filed: 1989-12-08
Abstract: PURPOSE:To efficiently refine an alloy having low content of total and S and few clusters by bringing the bath of a molten metal into contact with a CaO- CaCl2-CaF2 series slag forming agent having a specified compsn. in the atmosphere of an inert gas or an reduced pressure. CONSTITUTION:The compsn. of a slag forming agent is regulated to the one of CaO-CaCl2-CaF2 series constituted of >=20% CaCl2, <=40% CaO and <=80% CaF2. A Ca-Si contg. alloy is added to the bath of a molten metal, which is brought into contact with the above slag forming agent in the atmosphere of an inert gas or a reduced pressure. This method is applied to the bath of an alloy contg. about >=45%Mn.

Title: Production of hydrogen peroxide
Inventor: YAMADA NOBUO
IPC: C02F1/461
Filed: 1995-12-06
Abstract: PROBLEM TO BE SOLVED: To prevent the lowering of current efficiency in the method for producing an aq. alkaline soln. of hydrogen peroxide by supplying an aq. alkaline soln. and an oxygen-contg. gas to the cathode as a porous gas diffusing electrode to electrolyze oxygen by using an oxygen-contg. gas previously freed from carbon dioxide. SOLUTION: The air freed from carbon dioxide and the PSA oxygen freed from carbon dioxide are used as an oxygen-contg. gas freed from carbon dioxide. When the air contg. carbon dioxide is used as the oxygen source, the carbon dioxide contained in the air in a small-amt. is accumulated in the cathode, and the current efficiency is gradually decreased during the continuous operation. When the air freed from carbon dioxide is used, the same current efficiency as that when pure gaseous oxygen is used is attained. Since the ordinary air is used, the running cost is lowered. The PSA oxygen freed from carbon dioxide and nitrogen by a molecular sieve effect and having 95% purity is optimally used as the gas source.

Title: Pressure-contact roller
Inventor: ISHIDA KOUJIYUN
IPC: B65H27/00
Filed: 1995-12-06
Abstract: PROBLEM TO BE SOLVED: To narrow the diameter of a shaft by forming a roller shell and the shaft of the carbon fiber reinforced resin and/or the carbon fiber reinforced metal. SOLUTION: When a load is applied to both ends of a shaft 2 of a pressure- contact roller 1 by a presser means, the load presses a cylindrical rotor of the roller shell 3 through spherical bearings 4a, 4b. At this stage, a winding roller 7, which contacts with the cylindrical rotor through a sheet layer, is bent in the pressing direction, but the spherical bearings 4a, 4b are rotated within the longitudinal cross section of the shaft 2 so as to allow the bending of the cylindrical rotor. With the bending of the winding roller 7, the cylindrical rotor is evenly curved, and both the rollers are evenly nipped over the whole area in the axial direction through the sheet layer. The shaft 2 and the roller shell 3 are made of the carbon fiber reinforced resin or the carbon fiber reinforced metal. In this pressure-contact roller 1, rigidity of the shaft 2 is improved so that the diameter thereof can be narrowed by using the carbon fiber reinforced material for the shaft 2 and the roller shell 3.
