Title: Digit line driving circuit
Inventor: YAMAGUCHI KUNIHIKO
IPC: G11C11/34
Filed: 1982-08-27
Abstract: PURPOSE:To prevent the saturation of a transistor(TR) which is caused at an undershoot time, by adding a level clamping circuit using the TR to suppress the undershoot. CONSTITUTION:Level clamping TRs Q11 and Q12 and a terminal VC which drives their base potentials are added. By these TRs Q11 and Q12, potentials at nodes C1 and C2 have levels clamped to values which are lower than the potential of the terminal VC by values corresponding to forward voltages VBE between bases and emitters of TRs Q11 and Q12. Therefore, when the potential which is higher than desired low potentials of nodes C1 and C2 by the voltage VBE is supplied to the terminal VC, signal waveforms of nodes C1 and C2 at a transition time are clamped to desired potentials, and a signal of no undershoot is attained. Consequently, the saturation of the TR caused at the undershot time is prevented.

Title: Positioning indicator
Inventor: KITANISHI NORIYUKI
IPC: B23Q17/22
Filed: 1986-06-24
Abstract: PURPOSE:To speed up positioning of a workpiece by making the V groove of the tip end of the probe of a positioning indicator abut against a reference pin through lowering a spindle, moving a table so as to make the indication value of a gauze zero (0), and thereby adjusting the reference scale to be zero. CONSTITUTION:When a workpiece 40 is set on a table 51 with a reference pin 45 being fitted in the reference hole of the workpiece 40 and a sleeve 5 of a positioning indicator 1 is fitted to a spindle 50, a probe 20 moves to an upper end, then a dial gauge indicator 30 shows minus (-) graduation. Further, when a pin 45 is moved right under the probe 20 and the indicator 1 is lowered, and when a groove 23 is made to abut against the pin 45 and the indicator 1 is further lowered, force for pushing the groove 23 in the radial direction of the sleeve 5 is generated and the probe 20 is moved in the radial direction until the slant face of the groove 23 abuts against the peripheral face of the pin 45. Furthermore, when an probe 32 is pushed and pressed according to the movement of the probe 20 and the dial gauge 30 is moved so as to move the pin 45 to make the indication value zero, the spindle 50 and the pin 45 are thus aligned with each other, and then if the reference scale 52 of the table 51 is set to be zero, positioning of the workpiece is speedily completed.

Title: Automatic one-side tig welding method of pipe body
Inventor: MATSUURA TOSHIHIKO
IPC: B23K9/035
Filed: 1982-08-26
Abstract: PURPOSE:To subject pipe bodies to TIG welding in a large permissible error range in groove assembly by performing welding of the root layer in the TIG welding of the single U-groove of the pipe bodies while moving an electrode from above to below along the annular groove part and performing the welding of the 2nd and succeeding layers conversely from below to above while moving the electrode. CONSTITUTION:An electrode 5 is moved from the top to bottom end in an annular groove part 1 by a downward welding method in an arrow direction so that the melt flow 7 of molten metal is made to flow downward always in precedence to an arc 6. Since a root gap (d), and the gap of dislocation, etc. are filled, the stable root pass penetration welding without the slip-off of a backing material 3 is accomplished without applying the arc 6 directly to the material 3. Multilayer build-up welding is accomplished for the welding from the 2nd layer up to the final pass by moving the electrode 5 from below to above in accordance with a conventional method. As a result, the permissible range for the accuracy of the groove assembly in the circumferential butt welding in automatic one-side TIG welding of thick-walled and large-diameter stationary pipe bodies 2, 2 held in a horizontal or inclined position is made wider as compared to the conventional method and the working efficiency and the quality of the welded joint are improved.
