Title: Welding method of pipe and pipe plate
Inventor: HIRAYAMA SADAHIKO
IPC: B23K9/028
Filed: 1980-10-14
Abstract: PURPOSE: To facilitate the preparation work for welding and improve the reliability of welding by inserting a pipe shallow into a pipe hole provided to a pipe plate and performing TIG welding of plural passes by the procedure for inside surface fillet welding.  
     CONSTITUTION: A pipe 1 is inserted shallow into a pipe hole provided to a pipe plate 2. TIG welding is carried out along the fillet part formed by the end face of the pipe 1 and the inside wall of the pipe hole, by the procedure for fillet welding. This welding is carried out by superposing passes plural times until the penetration beads appear on the rear side of the weld line. At this time, the end part of an electrode 3 to be used is of a circular cone shape, and the diameter of the leading end is finished to a flat surface of about 0.5mm circle. The angle C of inclination of  the electrode 3 and the inside wall of the pipe hole is set at about 60°. According to this method, the pipe 1 and the plate 2 melt thoroughly at the inserted part and therefore the reliability of welding is high, and the possibility of  inducing crevice corrosion during the use of the product is eliminated.

IPC: G03G15/02
Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To provide an electrifier capable of obtaining a uniform and stable potential by electrification. SOLUTION: When voltage is applied to an electrifying electrode 2 from a DC power source 4 through a supporting roller 5, an electric discharge occurs in a very small gap in the vicinity of the contact part of the electrifying electrode 2 with a body to be electrified 1 to electrify it.

Inventor: TAKAMURA YOSHIYUKI
IPC: B65H3/54
Filed: 1986-06-19
Abstract: PURPOSE:To certainly take out the laminated sheet articles one by one by installing an adsorbing part which can be advanced and retreated relatively for an accommodation case for the laminated sheet articles and installing the supporting parts for pressing the side edges of the laminated sheet articles onto the accommodation case. CONSTITUTION:When the second sheet 21 and the succeeding sheets adhere successively onto the first sheet 21, an adsorbing part 6 relatively moves, and after the first sheet is adsorbed onto the adsorbing part, the first sheet is pulled up.

Filed: 1995-06-09
Abstract: PURPOSE: To make a drive circuit simple, by controlling a drive voltage in a way that an absolute value of a secondary differential term applied for an expansion and contraction time is larger than an absolute value of a critical secondary differential term that gives a boundary of dynamic and stationary frictional state between a drive plate and a moving body. CONSTITUTION: A drive voltage is controlled in away that an absolute value of a secondary differential term applied for an expansion time (t1 to t0 ) and a contraction time (t2 to t1 ) is made larger than an absolute value of a critical secondary differential term that gives a boundary of dynamic and stationary frictional state between a driving plate 12 and a moving body 15. When the piezoelectric elements 14a and 14b are shifted to the right during the expansion time, the drive plate 12 and the moving body 15 come in a dynamic frictional state, and the drive plate 12 is shifted just a distance of L5 relatively from the moving body 15, while the moving body 15 is not changed in position. When the piezoelectric elements 14a and 14b are shifted to the left, the drive plate 12 is shifted just a distance of L6 relatively from the moving body 15.

Title: Internal combustion engine
Inventor: SASAI KATSUHIKO
IPC: F02D15/04
Filed: 1979-11-06
Abstract: PURPOSE: To restrict a maximum combustion pressure to a lower value by providing a movable piston inside an auxiliary chamber which is communicated with a combustion chamber.  
     CONSTITUTION: When a pressure in a combustion chamber 5 is lower than a force of a spring 10, a movable piston 11 is pushed toward a communication hole 4 so that an auxiliary chamber 7 is not communicated with the combustion chamber 5. During a combustion stroke, when a piston 2 is beginning to be lowered after reaching a top dead center, the pressure in the combustion chamber 5 still rises due to the combustion. Once the pressure exceeds a force of the spring 10 applied to the movable piston 11, the piston 11 is pushed up inside the auxiliary chamber, thereby maintaining a maximum burning pressure low.
