Title: Current collector of trolley-assisted vehicle
Inventor: TAKEI HIDETOSHI
IPC: B60L13/00
Filed: 1985-07-22
Abstract: PURPOSE:To prevent a defect from occurring due to driver's electric shock or impact by enabling to lift a pantograph only when the door switch of a driver's cab is closed in a nontrolley mode. CONSTITUTION:When the door of a driver's cab is closed and a mode change over switch 5 is shifted to a nontrolley mode side, a pantograph control (PC) relay 15 is energized to close a contact 17. When the switch 5 is shifted to a trolley mode T side in this state, a pantograph-actuating solenoid valve 8 is energized to lift the pantograph. When the door is opened and the driver intends to separate in the state that the switch 5 is shifted to the trolley mode, any of door contacts 12, 13 is opened to deenergize the relay 15 to deenergize the valve 8, thereby automatically falling the pantograph.

IPC: B23K9/067
Filed: 1982-09-14
Abstract: PURPOSE:To eliminate the need for insulation measures and to reduce the size of a device, by bringing an electrode into contact with a base material, impressing a welding voltage thereon, and detaching the electrode from the base material after a prescribed time thereby, generating an arc without applying high voltage. CONSTITUTION:A slight voltage is impressed between an electrode 4 and a base material 5 by the command for starting welding, then a welding torches 2 advances downward. When the contact of the electrode 4 with the material 5 is detected from the decrease in the voltage, the torch 2 stops and a shielding gas is ejected. Touch current is conducted after a set time T1 to heat slightly the tip of the electrode 4 and after the time T2, the torch 2 is moved upward to generate an arc. A changeover circuit 7 for detection of arc length/electrode torch is changed over to the detection of arc length and an AVC is operated to pull up the torch 2 to the adequate arc length by the set initial voltage V1. The initial current I1 is conducted in the stage and the molten metal pool is forcibly expanded by the arc power. The set voltage of the AVC is set at V2 and the welding current at I2 after the time T3 and the normal welding is started.

Title: Solid-state laser device
Inventor: ANDO TETSUO
IPC: H01S3/05
Filed: 1993-06-30
Abstract: PURPOSE:To reduce space hole burning of the gain even in the case of uniaxial or biaxial crystal by providing a means for reducing space hole burning of the gain inside a laser resonator. CONSTITUTION:Laser light 7 (wavelength of about 809nvm) is converged to Nd:YVO4 9 by a converging lens 8. Coating nonreflective to a wavelength of 809nm and highly reflective to 1064nm is applied to a left side 9a. Coating of reflectance of 95% to 1064nm is applied to a left side 11a of an output mirror 11. A laser resonator is formed of the left sides 9a and 11a and a quarter wavelength plate 10 to 1064nm is arranged in an inside thereof. As for light of 1064nm, light polarized to a c-axial direction of the Nd:YVO4 9 gets out at first: however, when it passes through the wavelength plate 10, is reflected at the left side 11a and returned to the Nd:YVO4 9 again, its polarization direction is rotated by 90 deg.C. Since an a-axial direction and a c-axial direction differ in refraction factor, an interval in a place wherein light intensity of 1064nm becomes 0 is wider than that of one polarization direction and space hole burning of the gain can be reduced.
