Inventor: IIDA KEIZO
IPC: B23K20/12
Filed: 1985-12-04
Abstract: PURPOSE:To enable the friction pressure welding of a thin fine tube without causing any deformation on the joining part by performing a friction pressure welding by forming annular projection at the tip of the pipe for pressure welding in case of joining the thin fine diameter tube of Cu, Al, etc. with friction pressure welding. CONSTITUTION:Both pipe 11' and 12' are subjected to a friction pressure welding with advancing a fixed jig 4 by rubbing the fine tube 11' fitted to a threeway chuck 3 with an annular projecting part by turning it at high speed for the fine tube 12' fitted to a fixed jig 4 by forming the annular projection 2 at the tip of the fine tube 11', 12' to be joined, in case of joining with friction pressure welding the thin fine tube of less strength of Cu, Al, etc. A sufficient pressure welding sectional area is obtd. by the annular projection 2 and the deformation of the pipe in pressing can be prevented by the work hardening, and the thin fine tube of Cu, Al, etc., is joined with friction without deforming at its joining part.

Title: Ink supply device of screen printing machine
Inventor: HASEGAWA TAKAKUNI
IPC: B41L13/18
Filed: 1991-10-21
Abstract: PURPOSE:To rationalize the supply amount of printing ink to a screen printing surface even when hard printing ink is used and to accelerate the drying of the printing ink forming a screen printing image to printing paper. CONSTITUTION:A forcible rotary member 59 kneading printing ink is provided on the way of the ink supply passage supplying printing ink to the inner peripheral surface of a cylindrical plate cylinder 1 from an ink supply source.

Title: Blade replaceable cutter for book binding
IPC: B26D1/00
Filed: 1998-09-28
Abstract: PROBLEM TO BE SOLVED: To prevent chipping of a blade, reduce cutting noise, and keep a thickness of a cutter unchanged even when it is ground again by rotating a replaceable blade like offset blade type slitter knife to change a position of a cutting edge and providing a positive set angle in a tip edge part of the replaceable blade protruding from outer periphery of a cutter main body. SOLUTION: Since a replaceable blade 13 like offset blade type slitter knife enabling the change of a position of a cutting edge due to its turn is used, the number of blades is reduced, but the strength of the cutting edge 13a is increased, and it is possible to suppress chipping of the blade and shocking cutting noise having high frequency which is a harsh grating noise. Furthermore, regrinding of the replaceable blade 13 is done not on a rear surface 13d of the blade but on a swages face 13f. Therefore, when the replaceable blade 13 after regrinding is attached to a cutter main body 11, a thickness of a cutter is scarcely changed, and minute adjustment in cutter mounting becomes almost unnecessary.  In addition, since a tip part of the replaceable blade protruding from outer periphery of the cutter main body 11 has a positive set angle θ, the whole rear surface 13d of the replaceable blade 13 is not brought into contact with a cutting face, and cutting surface is not readily deteriorated.

Title: Synchronous detection circuit
Inventor: FUKUDA EISUKE
IPC: H04L27/22
Filed: 1989-10-20
Abstract: PURPOSE:To attain synchronous detection with an optimum carrier phase by fixing a four-multiplication output in a state where it is continuously given to a voltage control oscillator at the time of synchronous detection, and switch- controlling a reference carrier by means of a two frequency-dividing clock as it is or between a pi/4 shift so as to attain orthogonal detection. CONSTITUTION:A phase error signal outputted from four-multiplier 5 through an orthogonal detector 3 and a filter 4 is given to the voltage control oscillator 7 at every two time slots. In such a state, a carrier reproduction loop 1 executes an orthogonal detection operation equal to a case when a QPSK modulation wave is received at every time slot. When the voltage control oscillator 7 is controlled and the carrier reproduction loop is synchronized, the output of a synchronous detection circuit 9 changes, a switching control circuit 10 fixes an on/off control signal CS2, fixes a sample holding circuit 6 to be an on-state and switches a switching circuit 8 by an on/off signal SC1 corresponding to the two frequency-dividing clock 2CLK at every time slot. Thus, synchronous detection is attained with the optimum carrier phase.

Title: Semiconductor laser of variable wavelength
Inventor: NUMAI TAKAAKI
IPC: H01S5/00
Filed: 1988-10-28
Abstract: PURPOSE:To prevent enlarging of spectral line width when the wavelength is varied by inserting a buffer region to reduce a leak current between active and phase control regions of a variable wavelength Bragg reflection type laser and by optically coupling the active region and a distribution Bragg reflection region. CONSTITUTION:After electrodes 400, 410 are formed, a groove 170 is formed which enables electrical separation of a distribution Bragg reflection region 300, a phase control region 200, a buffer region 210, and an active region 100. When a current is injected to the phase control region 200 and a distribution Bragg reflection region 300, the wavelength of transmitted light changes to the short wave side, and increase of spectral line width is small. This means that a leak current is reduced due to the insertion of the buffer region.
