Title: Method of inhibiting contamination of molten metal
Inventor: SUGIURA SABUROU
IPC: C22C1/02
Filed: 1981-07-31
Abstract: PURPOSE:To satisfactorily inhibit contamination of a molten metal with the air, by supplying liquefied inert gas to the surface of the molten metal in a melting furnace to vaporize the inert gas. CONSTITUTION:Liquefied inert gas received in a pressure-resisting vessel 11 is supplied through a discharge pipe 16, a discharge valve 17 and a heat-insulating transport pipe 18 to a needle valve 19. The inert gas discharged from the needle valve 19 is let flow through a heat-insulating transport pipe 20 under a gas- liquid mixed condition, and separated into a gaseous part and a liquid part by a cyclone 22. The gaseous inert gas is discharged through the upper portion of the cyclone 22, while the liquid inert gas is let flow downwards through a fluid- outflow opening 22a and changed into liquid drops 29 on the surface of a molten metal 28 held under a heated condition by an induction coil 24. The liquid drops 29 are hippety-toppety scattered in all directions, and evaporated all over the surface of the molten metal 28. Consequently, the in-furnace atmosphere is efficiently speedily substituted from its lowermost layer, and the extremely proper uncontaminating atmosphere is formed.

Title: Arc apparatus
Inventor: AREKUSANDORU BASHIRIEBICHI BOR
IPC: H05B7/148
Filed: 1988-05-18
Abstract: PURPOSE: To reduce electric power for stabilizing an electric arc position by arranging a second coil at a position less than the value of an electric arc gap from a cylindrical first coil surrounding two electrode, and reversing the direction of current flowing therein. CONSTITUTION: When reverse direction currents are applied to respective coils 7, 8 from a power source 9, a non-uniform magnetic field is formed in an electric arc gap 6. Comparing with the magnetic field produced by one coil of equal power consumption, the same has minimum strength sharply confined to the axes of the coils 7, 8. Therefore, the modulus of magnetic field strength on a face vertical to the coils 7, 8 and passing the center of the electric arc gap 6 has a specified distribution. An electric arc providing diamagnetism is arranged in the minimum region of the magnetic strength in the electric arc gap 6, and the position of the electric arc is stabilized by the high gradient of the magnetic intensity. Thereby, electric power for stabilizing the electric arc position can be reduced.

Title: Slip detection device for drive wheel of vehicle
Inventor: YAMAGUCHI KEIICHI
IPC: F02D41/04
Filed: 1993-05-21
Abstract: PURPOSE:To prevent slip detection error during braking operation by forbidding calculation of slip quantity when a detection signal from a means of detecting brake operation as well as a means of detecting accelerator opening degree. CONSTITUTION:A throttle ECU52 obtains a speed difference from respective speeds detected by right and left driven wheel speed sensors 40L, 40R as well as right and left driven wheel speed sensors 39L, 39R at the normal time. Based on the speed difference the slip quantity of drive wheel is computed. A fully- closing switch 31a detects whether the opening degree of accelerator is fully closed or not. A brake sensor 42 detects operation of brake. When the fully closing signal of accelerator opening degree from the switch 31a and the detection signal of brake operation from the sensor 42 are output, the throttle ECU 52 forbids the calculation of slip quantity. It is thus possible to prevent detection mistake of slip upon brake operation.

Title: Adsorbing device
Inventor: NAITOU KAZUNARI
IPC: B65G59/04
Filed: 1982-07-09
Abstract: PURPOSE:To prevent dark color from adhering to a light color dyeing single plate even if the light color dyeing single plate is vacuum-adsorbed after a dark color dyeing plate by providing non-air permeable cushion material having through holes, which adheres to the suction hole area of the main body surface of the adsorbing device so that the through holes communicate with the suction holes. CONSTITUTION:A lot of suction holes 4b are mounted on the lower portion of the main body 4 of the adsorbing device, and non-air permeable cushion material 5 is layed and sticked to the lower surface of the main body 4. Through holes 5a communicating with the holes 4b are formed on the material layer, and a water-repellent sheet 6 is adhered to the lower surface of the cushion material 5 outside the holes 5a. Since the cushion material 5 is formed of non-air permeable material, when a dyeing single plate is adsorbed, dyeing liquid will not soak into the cushion material 5, that is, at the next adsorbing, the dyeing liquid will not ooze from the cushion material 5. Accordingly, even if the light color single plate is vacuum-adsorbed after the dark color, the dark color will not adhere to the light color single plate so as to prevent production of a bad single plate.
