Filed: 1984-11-27
Abstract: PURPOSE:To suppress an evaporation of plated zinc by preheating an Al material by a specified condition, when cladding a brazing filler metal, and brazing the zinc plated Al material, in an N2 gas atmosphere. CONSTITUTION:For instance, a fin cladded with a brazing filler metal, and a zinc-plated tube are assembled temporarily, and also a radiator core 1 applied a fluoride compound flux is heated fro 20-60min at a melting temperature or below of the brazing filler metal, in the atmospheric air by a preliminary heating furnace 2. In this case, zinc plated to the tube starts a diffusion, and a desired diffused layer is formed within said time. Also, this temperature rise is executed in the atmospheric air, therefore, the dezincing quantity is reduced comparing with a conventional system. Subsequently, a preliminarily heated core 1 is fed to a brazing furnace 3 being under an N2 atmosphere, each tube and the fin are brazed, and a brazed Al core 4 is obtained.

Title: Optical scanner
Inventor: MORI SHUJI
IPC: G02B26/10
Filed: 1987-10-02
Abstract: PURPOSE:To easily correct scanning distortion in the main scanning direction and a scanning error in the sub-scanning direction due to the surface inclination of a deflector by arranging a 1st cylindrical optical member forming an image only in the main scanning direction on a scanning surface and a 2nd cylindrical optical member forming an image only in the sub-scanning direction on the scanning surface. CONSTITUTION:Light beams uniaxially converged by a 1st convex cylindrical lens 4 are deflected by the deflector 5 and reach the scanning surface 7. At that time, a 2nd convex cylindrical lens 6 arranged between the deflector 5 and the scanning surface 7 acts in the main scanning direction simultaneously with a parallel plane transparent optical member, and corrects the scanning distortion of the light beam. With respect to scanning errors in the sub-scanning direction, the 2nd convex cylindrical lens 6 corrects converged beams made into parallel luminous fluxes by a collimate lens 3 when they make incident on the deflector 5 possessing deflecting difference due to its surface inclination. Thus, scanning distortion in the main scanning direction, which are caused by the surface inclination of the deflector, can be readily corrected.

And the control part 10 makes, at the pilot signal position of own track, a third register 13 latch the offset value corresponding to the level difference between the two heads, and then, both heads compare the level differences of the inter-crosstalk components at the position where the pilot crosstalk components between tracks are alternatively reproduced, and the ATF error is corrected at an adder 14 and a generated PWM signal is impressed on the ATF control signal. Thus, an ATF function is automatically performed.

Title: Permanent magnet
Inventor: UCHIDA KIMIO
IPC: H01F1/053
Filed: 1988-10-04
Abstract: PURPOSE:To stably manufacture a high-performance permanent magnet by mixing Co to specific principal constituent elements contained in specific weight percentages. CONSTITUTION:This permanent magnet contains 22-28wt.% R (R: rare earth elements), 10-25wt.% Fe, 1-10wt.% Cu, 0.2-5wt.% M1 (M1: one of Zr and Hf), and 0.05-5wt.% M2 (M2: at least one of W and Mo). When the adding quantity of W and Mo is more than 0.05wt.%, the break in the second quadrant disappears and the angularness is improved, but, when the quantity is more than 5wt.%, no merit can be expected from the addition, since the density of residual magnetic fluxes considerably drops and the coercive force also slightly decreases. By adding the high-melting point element of W or Mo by an appropriate quantity in such way, the angularness in the second quadrant of this R2Co17 permanent magnet is improved.
