Title: Production of welded pipe
Inventor: KOU TAKAO
IPC: B23K13/02
Filed: 1981-07-24
Abstract: PURPOSE:To prevent the oxidation of alloy components in a blank material and the generation of penetrators in the stage of producing a welded pipe by irradiating a laser beam near the welding point and welding the blank material while allowing the metal in the irradiated part to evaporate. CONSTITUTION:A steel strip is fed and is formed to a U shape; further, it is formed approximately to a circular shape to form an open pipe OP. Both opposed edges of the open pipe are accurately guided and the pipe is fed into an induction heating coil 1. High frequency current is supplied to the coil 1 to heat the opposed side edge parts. The open pipe OP heated at said parts is pressurized with squeeze rolls 3l, 3r and are welded at a welding point A, by which a pipe P is formed. A laser beam generator 7 is installed above the point A, and irradiates a laser beam to the area near the point A. The metallic surface near the point A evaporates and the metallic surface is shielded from the atmospheric air by the vapor pressure thereof, whereby a non-oxidative atmosphere is maintained around the heated parts.

Title: Semiconductor joining laser forming method
Inventor: SAKUMA ISAMU
IPC: H01S5/00
Filed: 1978-09-21
Abstract: PURPOSE: To obtain a high-conversion-efficiency semiconductor joining laser by enclosing an activation layer with low-reflectivity substances completely.  
     CONSTITUTION: An n-type Al 0.3 Ga 0.7 As 10, a GaAs 11 and a p-type Al 0.3 Ga 0.7 As 12 are piled on an n-type GaAs 9 in layers and the layer 12 is provided with grooves having a width of 20μm and reaching the layer 11. And the layer 11 is melt-backed, it is stopped when reached the layer 10's surface, and a p-type Al 0.3 Ga 0.7 Al 13 and an n-type Al 0.3 Ga 0.7 As 14 are piled in layers. By using a constant growth temperature and a constant cooling speed, crystal surface is flattened. Since epi-growth does not occur on the surface of AlGaAs which has been once aerated, no growth layer is formed on the layer 12 by the 2nd epi-formation. And then, electrodes 18 and 19 are prepared. When the groove width is less than 100μm, an embedded type jointing laser can be easily formed with high reproducibility and recovery, and if the electrode 18 is positive, the most part of the current needed for radiation of the activation layer is caught by the layer 15, conversion efficiency is heightened.

Title: Purification of triglyceride oil
Inventor: KORUNERISU IGUNATEIUSU DE RAAT
IPC: C11B3/06
Filed: 1983-06-28
Abstract: Process for refining a triglyceride oil comprising bringing the oil into contact with at least an amount of aqueous alkali solution equal to the stoichiometric amount required to neutralise the oil, forming a soapstock and separating said soapstock and oil characterised by bringing the oil into contact with the aqueous alkali solution at a temperature in the range of from 40 to 140°C and forming at a temperature in the range of from 40 to 140°C a soapstock which contains with respect to the initial fatty acid content of the oil at least about 0.7 wt% of electrolyte and which comprises a member selected from the group comprising a single phase of neat soap, a binary phase mixture of neat soap and niger, a binary phase mixture of neat soap and lye and a ternary phase mixture of neat soap, lye and niger. Each of the niger, lye and neat soap phases is a single phase comprising water, electrolyte and soap. The lack of substantial amounts of free water reduces saponification and thus oil loss. The presence of niger and/lye can reduce the viscosity of the soapstock and hence aid its separation from the oil.

Title: Counter circuit
Inventor: ICHIBAGASE HIROSHI
IPC: H03K23/54
Filed: 1987-05-15
Abstract: PURPOSE:To enable fast operation even when the number of stages of counters increases by employing wired-OR constitution for an input to an initial-stage flip-flop circuit. CONSTITUTION:This counter circuit includes a shift register 1 consisting of (n) flip-flop circuits D-FF and an OR circuit 3 which inputs respective outputs Q of the initial stage - (n-1)th stage of the flip-flop circuits DF1-DFn, and the output of this OR circuit 3 is supplied to the initial-stage flip-flop circuit through a wired OR circuit 4. Thus, the Q output of the shift register is shifted to the right successively in response to '0' significance and the wired-OR constitution is employed for the input to the initial-stage D-FF, so even if the number of the stages of the counters increases, the propagation time from the outputs of the 2nd and succeeding D-FF to the input of the initial stage becomes longer only by one gate. Consequently, the fast operation can be secured.
