Title: Insertion of fine heat transfer pipe
Inventor: SATOU MASATOSHI
IPC: F28F9/16
Filed: 1982-04-12
Abstract: PURPOSE:To obtain highly reliable joint construction of pipe and tube plate by a structure wherein fine heat transfer pipes, in the end of which a thin pipe is inserted, are inserted in the holes of the tube plate and expanded and, after that, the ends of the fine heat transfer pipes are welded to the tube plate. CONSTITUTION:Firstly, the inside pipes 12 are inserted in the respective fine heat transfer pipes 5. Secondly, the fine heat transfer pipes 5 are inserted in the tube holes of the tube plate 1 in order to fix to the tube holes by expanding the pipes. Thirdly, the fine heat transfer pipes 5 and the inside pipes 12 are sealed by seal-welding or brazing at the positions 9 and 10. Skin tension is developed on the surface of the inside pipes 12, however the influence of said skin tension does not be exerted upon the fine heat transfer pipes 5. In addition, because the inside pipes 12 extend upward a little beyond the thickness of the tube plate 1, the final ends of the expansion of the pipes can be protected by the inside pipes 12, resulting in obtaining highly reliable joint construction of pipe and tube plate. Owing to the double structure at the part of the tube plate only as mentioned above, no heat conductivity and pressure loss nearly influenced, resulting in deteriorating no thermal efficiency.

Title: Pulse light current extraction circuit
Inventor: KUNIEDA TAKESHI
IPC: H03F3/08
Filed: 1988-03-14
Abstract: PURPOSE:To accurately separate an optical pulse signal as a voltage proportional to the intensity of light by providing an operational amplifier whose input terminal connects to an anode of a photoelectric element and to the input terminal and output terminal of which two negative feedback circuits are connected. CONSTITUTION:With a steady-state light received and a DC current I sent from an anode of a photoelectric element 1, then the DC current I all flows to a transistor(TR) 4 by the negative feedback action of a buffer circuit 3 and its output terminal 8 is kept to a reference potential. When a pulse light is superimposed on the steady-state light, a current I+i being the superimposition of a pulse current (i) on the DC current I flows to the anode, but the base potential of the TR 4 cannot follow a steep change by the action of a capacitor 6 and the collector is kept to a high impedance with respect to a current over the DC current value I. Thus, all the current (i) flows to a resistor 10 and the potential at the terminal 8 changes by a voltage iR1 proportional to the intensity of the pulse light from the value at the steady-state light. Thus, a current iD of a negative feedback diode 18 of an operational amplifier 17 is expressed as equation and an optional amplification factor is obtained by selecting the resistance of the resistor 10 sufficiently larger than that of a resistor 16.

Title: Direct current mig welding
Inventor: ICHIHARA IZUMI
IPC: B23K9/16
Filed: 1978-05-19
Abstract: PURPOSE: For high speed welding that prevents magnetic blow, current is made in the same direction when filler metal is upstream of electrode in welding direction, and current is made in the reverse direction when it is downstream, thereby always directing arc at weld forwarding direction.  
     CONSTITUTION: In direct TIG welding, when filler metal 6 is upstream in welding direction, the base material 1 is made positive and the electrode 2 negative, so that the filler metal 6 is the same porality as the electrode 2. Such same porality generates attracting magnetic field to cause arc column to direct at forward welding direction. When filler material 6' is down stream of welding direction, the filler metal 6' is made positive and the base material 1 negative so that the filler metal 6' and the base material 1 are in reverse porality. This generates repulsive magnetic field to cause arc column 3 to direct at weld forwarding direction. Thus, the process provides neatly beaded high-speed welding.
