Title: Consumable electrode system gas shielded arc welding method
Inventor: UKAI JIYUN
IPC: B23K35/38
Filed: 1979-05-24
Abstract: PURPOSE:To make possible the prevention of damaging of backing strips and the defect-free multi-layer welding of I-beam steel by specifying the mixing ratio of Ar and CO2 being shielding gas at the first and second and subsequent layer welding while automatically feeding a wire to the base metal groove applied with the backin strip made basically of copper. CONSTITUTION:A welding wire 2 from a welding torch 1 is positioned at the center of the groove spacing of the base metals 3 contacted with a backing strip 5 of copper or the alloy composed primarily of copper. In the first layer, the mixed gas of 65- 100% Ar and 0-35% CO2 is used as shielding gas and in the second and third layers, it is changed to the mixed gas of 0-50% Ar and 50-100% CO2, whereby the multi-layer welding of I-beam steel is done. As a result of this, arc 10 generates directly in the strip 5 in part but its potential gradient is small, resulting in smaller energy density. If the current value and welding speed are proper, the strip 5 does not melt. In the second and subsequent layers, CO2 which is inexpensive and gives deep penetration is much used.

Filed: 1982-04-16
Abstract: PURPOSE:To load and unload a disk securely through a single mechanism, by bringing a disk receiving member into contact with the disk when the cover is opened, and leaving the disk when the cover is closed in interlocking with the operation of a motor to open and close the cover body. CONSTITUTION:When the reproduction of the disk D ends and a cover is opened by an operating button, not shown, in the cover is closed state which is shown in the figure, a motor 12 rotates and its rotation is decelerated by a gear 13; and a cam member 15 is turned in a direction A to disengage from a lever 19, which turns around a shaft 18 in a direction C by a spring 20. The disk receiving member 25 contacts the disk D, which is then detached from a clamper to rotate the cover 1 in a direction E while the disk D is pressed up to an opening 3 to be taken out. When the disk D is inserted into the opening 3 during cover closure and the operation button is pressed, the motor 12 and respective mechanism parts operate reversely and a lock lever 21 and the lever 19 engage each other to return to their initial states. Consequently, the single mechanism opens and closes the cover and also drives the disk receiving member securely.

Title: Gyro-guide type unmanned carrier
Inventor: SUGIMOTO YUICHI
IPC: B61B13/00
Filed: 1986-03-24
Abstract: PURPOSE:To minimize the arithmetic error for the position of an unmanned carrier despite a large steering angle and to improve the stopping accuracy, by calculating the real shift amount between the center position of the carrier and the rotational center of a wheel of the carrier based on the information on the rotational frequency of an optional one or plural ones of wheels of the carrier as well as the wheel steering angles. CONSTITUTION:A rotary sensor 3 counts the distance pulses of the wheels diagonal with each other to obtain a distance traveled for a unit time. Then a steering angle rotary sensor 41 obtains an angle between a wheel and the carrier body. A traveled distance correcting part 42 calculates the average traveled distance per unit time of each of both sensors 3 and 41 to define a distance traveled per unit time. This obtained distance is set at DELTAl approximately equal to the shifted distance at the center part of the carrier. As a result, no error is produced with calculation of the carrier position despite a large steering angle and therefore the stopping accuracy is improved for the carrier.

CONSTITUTION:A stator is functionally divided into two parts and such a part which is magnetically connected to a rotor core 31 with a small gap provided between them is divided into a core 12 and a core 13 which magnetically connects 2 cores 12 in the axial direction. The pole core 12 is opposed to the rotor core 31 with a gap maintained between them. To make the gap smaller, the outer circumference of the rotor core 31 is circular and the internal surface of the pole core 12 of the stator is circular in construction. Further, the length of the outer circumference of a yoke core 13 connecting pole cores 12 is made smaller than the circumferential length of the outer diameter of the rotor core 31 at least. When an AC current is caused to flow through the winding wound around the outer circumference of the yoke core 13, a magnetic flux flows through a passage like 41 and an AC magnetic flux flows inside the winding of the rotor, and by this, a voltage is induced in the winding of the rotor and electric power is sent to the side of rotor from the stator side.
