Title: Production of metal composite pipe
Inventor: YASUDA SUKENORI
IPC: B21C37/06
Filed: 1978-12-28
Abstract: PURPOSE: To produce the metal composite pipe of smooth and highly aesthetic weld face by making the overlap width of the end parts of the metal plate covering the outside circumference surface of a steel pipe of less deviations in outside diameter as narrow as possible and supplying the current of a small ripple factor to the overlap part.  
     CONSTITUTION: The overlap part 3 of a covering metal plate 2 such as of stainless steel or Al is positioned to the bottom surface of an upper electrode 4 and a metal pipe 1 covered with the metal plate 2 is advanced at a specified speed in the pipe axis direction between the roll 4 and lower electrode roll 5. At this time, the overlap width of the metal plate 2 is made the length less than about 4 times the thickness of the metal plate 2. Along with the advancing of the covered steel pipe 1, the current of less ripple factor, e.g., 3-phase AC having undergone halfwave rectifying, DC, square wave current or high frequency current, is supplied to the overlap part 3 through the electrode rolls 4, 5. The entire part of the overlap part 3 is melted by this welding current and is rolled smoothly nearly equal to the thickness of the metal plate 2 by the screw-down force of the electrode roll 4.

Title: Record player
Inventor: KOBAYASHI ISAO
IPC: G11B19/14
Filed: 1979-12-17
Abstract: PURPOSE: To realize an automatic returning for a record player with a high reliability, by detecting several different end positions via a single position detector and  at the same time deciding the malfunction due to the eccentricity or the lead-out  groove of a large pitch by providing a 1-turn timer or the like.  
     CONSTITUTION: The 1-turn timer 18 is set when the slit 9 of the shutter plate 8 passes through the end position X, and the state of the detection signal given from the phototransistor 11 is checked after a turn of the record disk 1. If the result of check shows "1", the arm 2 is returned. The output of the phototransistor 11 is cleared with every change of "0"→"1"→"0" to start a turn newly. Then the signal S 4  which falls when the output of the transistor 11 continues for the time of a turn or longer is delivered to the timer 18. The end position is decided at the time point of the fall to set the bistable circuit 20, and thus the signal S 5  is delivered. In such way, the malfunction due to the eccentricity can be prevented.

IPC: B21C47/02
Filed: 1998-06-11
Abstract: PROBLEM TO BE SOLVED: To minimize looseness of a workpiece without damaging it and to reduce the size of the device by moving and controlling the device vertically in the transporting direction of the workpiece based on the moving quantity of the XY table. SOLUTION: In the case where the XY table moves in the X axis direction, the looseness of a workpiece W is increased between the roller 22 for controlling loop on the unwinding side and the fixing roller 23 on the unwinding side. The adjustment of looseness is done by the roller 22 by the command of a controller 103 for loop controlling roller, with the looseness adjusted to within a specified value. It is done similarly on the side for carrying out the workpiece. In the case where the XY table 9 moves in the Y axis direction, a slide table 4 moves along the XY table. With the moving quantity larger than a prescribed value detected by an XY moving quantity detector 101, a servo motor control part 102 drives a servo motor 8, making the slide table 4 follow up the XY table 9 and holding the positional relation between the workpiece W and the XY table 9.

Filed: 1999-06-10
Abstract: PROBLEM TO BE SOLVED: To remove a contaminant in a semiconductor without increasing production cost by heating both a first thin-film layer undoped with an amorphous semiconductor on one main surface of a semiconductor substrate and a one conductive type second thin-film layer made of amorphous semiconductor formed thereon. SOLUTION: A first thin-film layer 2, made of undoped amorphous silicon undoped, is formed by a plasma CVD method on the main surface of a semiconductor substrate 1 made of n-type single-crystal silicon. Then, a second thin-film layer 3 made of p-type amorphous silicon is formed on the first thin-film layer 2 by the plasma CVD method. The semiconductor substrate 1, on which the first and second thin-film layers 2 and 3 are formed, is heated to crystalize a laminate of the layers 2 and 3 and form a crystalized film 4. In this case, contaminants in the semiconductor substrate 1 are included in the crystalized film 4, and heat diffusion of a p-type impurity contained in the second thin-film layer 3 is suppressed by the first thin-film layer 2, thus preventing the p-type impurity from entering the semiconductor substrate 1.
