Abstract: PURPOSE:To make He liquefier and storage tank needless and to simplify the operation by a method wherein the heat exchangers coming into heat contact with the low temperature part of He liquefier is provided on a He gas collecting line after cooling a conductor to pass He supplying a cryostat with liquid He. CONSTITUTION:When a superconductive magnet 8 is in normal operation, any evaporated gas of liquid He 7 is liquefied by means of a condenser 5 making the pressure and liquid level in a cryostat 16 constant. When the current values in the magnet 8 are changed, a conductor 14 is charged with evaporated gas of liquid He to be stored temporarily in a tank 11. After the magnet 8 is set for normal operation, an adjusting valve 6 is slowly opened to pressurize the inside of the cryostat 16 liquefying the He gas by the action of the condenser 5. To accelerate the liquefying speed, two coolers provided stepwise are supplied with He gas stored in the tank 11 via value 6 through heat exchangers 17, 18 to rapidly recover the level of liquid He. In such a constitution, a superconductive device subject to simple operation at low cost may be manufactured.

Title: Disturbing wave evading system
Inventor: TANAKA SHOJI
IPC: H04B7/26
Filed: 1991-04-19
Abstract: PURPOSE:To secure the successive services with reduction of a disturbing wave area and the evasion of the disturbing waves by controlling the transmission/ reception power of the transmitter and the receiver of a radio base station after detecting the disturbing wave intensity to the base station. CONSTITUTION:The radio waves are received by a receiver 5 and sent to a demodulator 6 and a received radio wave intensity detector 7. A received signal deciding part 8 decides the reception of a normal signal or a disturbing wave based on the signal demodulated by the demodulator 6 and the received radio wave intensity signal outputted from the detector 7 and sends the normal received signal or the disturbing wave intensity signal to a reception control part 9. When the part 9 receives the normal received signal, the part 9 sends the present state level to a main control part 10. Meanwhile the part 9 sends the disturbing wave evading level to the part 10 as the value equal to the disturbing intensity when the part 9 receives the disturbing intensity signal. Then a transmission control part 4 instructs a transmission output control part 3 to reduce the transmission power of a transmitter 1 by a degree equivalent to the disturbing wave evading level with an instruction of the part 10.

Title: Electric discharge lamp
Inventor: HOSHIYAMA TADASHI
IPC: H01J61/16
Filed: 1982-05-24
Abstract: PURPOSE:To prevent the rise in temperature of an electrode to the utmost by the rapid delivery to the electrode of the cooling effect of a water-cooled tubular quartz case by adding such a minute amount of helium gas as not to influence the luminous characteristic of the tube, to crypton gas which is charged in the tube. CONSTITUTION:The internal space 4 of a case 1 is filled with mixture gas consisting of krypton and helium at a pressure of 2-8 atmospheric pressure, for example, at 5 atmospheric pressure. The optimum mixing ratio of krypton gas to helium gas is 80-99% to 1-20%. The thermal condutivity of krypton gas is 0.88X10<4> (J/(cm.s.k)), while that of helium gas is 14.15X10<4>(J/(cm.s.k)) which is about 15 times that of krypton gas. Furthermore, since the thermal conductivity of gas in most cases dosn't depend upon pressure of over several mm.Hg, the thermal conductivity of the charged gas containing 1-20% of helium is improved to about 15 times that of an electric discharge lamp containing 100% crypton gas. As a result, the cooling efficiencies of a cathode 2 and an anode 3 during operation are greatly improved.

IPC: B21D51/26
Filed: 1986-04-16
Abstract: PURPOSE:To form a welded step part having improved beauty and repair characteristic by allowing a material near end faces to flow outward in a circumferential direction along a graded face and executing mush seam welding at the time of welding. CONSTITUTION:A can body forming body 11 is fed into the spacing between electrode rolls in such a manner that the end face 11a1 of a lower end edge 11a in an overlap part 12 is positioned on part 17a of a main part 17 near the graded face 18a. The thickness in the part corresponding to the overlap part 12 decreases on progression of the mush seam welding and the material in this part flows outward in the circumferential direction, i.e., projects. The material near the end face 11a1, therefore, flows outward in the circumferential direction along the graded face 18a or further along the projecting face 18b. Projected iron or the like formed on the part near 20 the bottom surface on the outside of the end face 11a1 at the upper end edge 11b is crushed to the sectional shape corresponding to a side edge projecting part 18 and is substantially annihilated even if such projected iron or the like is formed. The inside surface side step which has a gentle grade in the greater part and permits easy repair is thus formed.

Abstract: PURPOSE: To make possible the formation of mesa-shaped grooves with gentle side face by etching with resist ink for silk screen printing as mask.  
     CONSTITUTION: Resist ink layer 8 is selectively formed through printing on a semiconductor wafer 3 by the silk screen printing method to be dried for solidification; after selectively removing the resist ink layer 8 by photo corrosion carving, a wafer 3 is etched with the resist ink layer 8 as etching mask to form scheduled grooves. Under this method, the adhesion between the resist ink layer 8 and a wafer 3 is relatively weak, so that mesashaped grooves 9 with side face 9a of gentle incline can be produced. Thus, when glass powder is filled in a groove 9a, it does not come off because of mechanical vibration, etc., to cover as sufficiently thick glass film 7.
