Title: Electrodeless discharge lamp
Inventor: ANAMI SHINICHI
IPC: H01J65/04
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To provide an electrodeless discharge lamp in which a reduction of luminous flux, a change of light color or a shape change of an induction coil is not produced even after a long time usage, and the induction coil and a means for holding the coil shape can be formed of inexpensive material. SOLUTION: A spheroidal valve 1 is covered with a capsular external tube 2 the inside of which is kept in vacuum. The external tube 2 is inserted and placed in an almost cylindrical coil shape holding means 4. A groove 5 is spirally formed on the surface of the coil shape holding means 4, and an induction coil 3 is wound around in the groove 5. The induction coil 3 is formed into a tape shape out of metal material such as silver, and is adhered and fixed to the means for holding a coil shape 4 at both ends of the winding part and several places on the winding part by a heat resistant adhesive 6. Since a temperature rise of the induction coil 3 is thus suppressed, a reduction of luminous flux, a change of light color or a shape change of the induction coil is not produced even after a long time usage and the induction coil and the coil shape holding means can be formed of inexpensive material.

Title: Inner face bead removing device of electric welded tube
Inventor: ONO EIJI
IPC: B23K7/06
Filed: 1984-12-10
Abstract: PURPOSE:To provide the titled bead removing device enabling to remove beads efficiently with gathering O2 gas from the bead side part to a bead part, by directing two pieces of scarfing nozzles for close to a sean welding position and by arranging symmetrically on a seam both scarfing nozzles. CONSTITUTION:An electric welded tube 1 is produced by forming a skelp in circular shape and performing an electric resistance welding by pressing by a squeese roll so as to abut both edges 5, while O2 gas is spouted from a scarfing nozzle 9 and auxiliary heating nozzle 13 by feeding a pressurized O2 to an oxygen conduit pipe 7 and 13. The O2 gas jetted from the nozzle 9 is flowed toward the seam along the inner peripheral face of the pipe 1 from the side part of the bead 6 and removes excess bead 6 by blowing off with oxidation the high temp. bead 6. Because of the O2 gas flowing so as to gather to the bead part at this moment, the O2 gas acts without waste on the bead removal and removes the bead 6 easily due to its high density. The O2 gas sprayed on the head 6 is directed for the upstream side and diffused in the air from an open pipe 2.

Title: Detection system for actuation ready state
Inventor: YAMAKADO KENJI
IPC: B41J2/44
Filed: 1985-11-19
Abstract: PURPOSE:To not only shorten a wait time, but also to eliminate the need to interpose firmware by detecting the rotating states of a laser source and a motor and deciding whether a device is ready to operate or not, and then starting the device. CONSTITUTION:A power reset signal is inputted to counters 11 and 17 and an F.F. 12 simultaneously with the operation of the power switch of the device, thereby initializing respective circuits. Simultaneously, a spindle motor 35 which drives the laser source 1 and a polygon mirror 2 is actuated. When the output of the laser source 1 increases and the device becomes ready to operate, the output of a laser photosensor 5 also reaches a certain value and the output of an amplifier 6 becomes larger than a reference value cf, so that an output signal SINW is obtained from a comparator 7. When a spindle motor 35 which drives the polygon mirror 2 reaches a prescribed rotating speed, the signal coincides with the output signal WINDW of a decoder 14 all the time, so an output signal SINWO is inputted to the F.F. 12 and an OR circuit 13 from an AND circuit 10 at every specific period, so that a host device detects the operation ready state of the device.

The material is thereafter subjected to a descaling and lubricating treatment. The respective parts of the upset product are nonuniformly strained and the spheroidization is dispersed if the tip angle of the above-mentioned dies is off the above-mentioned range.

IPC: F25B39/00
Filed: 1994-09-29
Abstract: PURPOSE: To connect a heat exchanger and an expansion valve to each other even in the case where the interval between refrigerant pipes of the heat exchanger is different from the interval between communicating holes of the expansion valve, by freely varying positions of respectively paired holes so as to be brought into agreement with the interval between outlet and inlet holes of the heat exchanger, or with the interval between the holes of the expansion valve. CONSTITUTION: A swollen part 20a forming a protrusion 25 of an outlet and inlet hole 21, which is inserted into a hole of an expansion valve mounting member 30, and a swollen part 20b forming a protrusion 26 of an outlet and inlet hole 23, which is inserted into a hole of the expansion valve mounting member 30, are covered with an end plate 4. In this case, the interval between a hole 37 and a hole 38 of a plate member 35 is brought into agreement with the interval between the protrusions 25, 26 of outlet and inlet passages 22, 24, and the interval between a hole of a protrusion 39 of a plate member 45 and a hole of a protrusion 40 thereof is brought into agreement with the interval between holes 51, 52 of an expansion valve 50, thus setting respective intervals separately from each other.  By this method, it is unnecessary to bring the interval between the holes 51, 52 of the expansion valve 50 into agreement with the interval between the outlet and inlet holes 21, 23. Therefore, even in the case where either one of a heat exchanger or the expansion valve 50 is made small in size, the both can be connected to each other.

Abstract: An H2S-containing feed gas is burned in at least one burner which opens into a combustion chamber, using oxygen and air. This gives a gas mixture containing H2S and SO2 to be converted into elemental sulphur by the Claus process. Oxygen is passed in through the central tube (13) of the burner, the H2S-containing feed gas is passed in through at least one second tube (14) which surrounds the central tube coaxially, and air is passed into the combustion chamber through a coaxial outer tube (15). The burner is charged with an H2S-containing feed gas whose hydrocarbon or CO2 content is at least 5 % by volume. At the orifice of the burner, the flow rate of the oxygen is 50 to 250 m/sec and that of the H2S-containing feed gas is 10 to 30 m/sec. In the core zone (18) of the burner flame, temperatures in the range from 2000 to 3000 DEG C are produced, and a gas mixture having temperatures of 1350 to 1650 DEG C and containing at least 2 % by volume of CO and at least 8 % by volume of H2 is discharged from the combustion chamber.
