Inventor: DOKOU TAKENOBU
IPC: B23K1/19
Filed: 1994-10-03
Abstract: PURPOSE: To miniaturize a heat exchanger and to realize the weight reduction and the recycling. CONSTITUTION: Aluminum alloy brazing filler metal has the composition consisting of, by weight, >7.0% to i 12.0 Si, >1.0% to <=8.0% Cu, >0.5% to <=6.0% Zn, >0.05% to <=1.2% Mn, >0.05% to <=0.5% Fe, and the balance aluminum with inevitable impurities. Because the brazing can be achieved at low temperature, the buckling of a fin 2 during the brazing, deterioration of the thermal conductivity due to re-solution of the precipitate, melting of a member of high strength during the brazing, deterioration of the corrosion resistance of a tube 1 due to the diffusion of the alloy elements, or the like are prevented, and the miniaturization and the weight reduction of a heat exchanger become possible.  The brazing filler metal contains Si, Fe, Cu, Mn and Zn as the essential elements, and these alloy elements are contained in the major alloy elements of other members of the heat exchanger, and the scrap of the heat exchanger can be re-used as the raw material of the heat exchanger.

Filed: 1988-09-26
Abstract: PURPOSE:To receive braking torque only on the rear portion of a rear arm for thinning and lightening the rear arm by locating a portion of the rear arm engaging a bracket supporting a brake member in the rear of a rear wheel. CONSTITUTION:An end piece 8 slidably fitted in a recessed groove 1d is mounted in the rear end of a rear arm 1. A caliper bracket 7 coupled with a caliper 6 is formed on the rear position behind a rear axle 9 with a recess 7a engaging the inside of the end piece 8 through an elastic rubber 12. When a brake is applied, a pad of the caliper 6 is pressed against a brake disk 5 to be pivoted in the direction (a) by the compressive deformation of the elastic rubber 12 for braking. Then, since the portion of the caliper bracket 7 engaging the end piece 8 is located behind the rear axle 9, braking torque acts only on the position of the rear arm 1 behind the rear axle 9, so that the portion of the rear arm in front of the rear axle 9 can be thinned and lightened.

Patent JP-S60131647-A (JP)
Title: Wavelength plate
Inventor: MORI SHIYUUZOU
IPC: G11B7/1365
Filed: 1983-12-20
Abstract: PURPOSE:To simplify a means which gives the return light to a semiconductor laser by using a lambda/4 wavelength plate which is set at a wavelength shorter than the wavelength of the semiconductor laser by a specific ratio. CONSTITUTION:When the wavelength of a semiconductor laser 1 is set at 8,300Angstrom , the luminous flux passed through an optical system receives the conversion of direction by a mirror 2 and is transmitted through a lambda/4 wavelength plate 3 to undergo P/S conversion. In this case, the quantity of light can pass through the plate 3 about 100% if the plate 3 is previously set at 8,300Angstrom . However the plate 3 is set at such a level where a 100% function is attained with a wavelength shorter than 8,300Angstrom  by 5-10%. As a result, the output light quantity of the plate 3 is reduced less than the original incident light quantity to be returned to the laser 1 with a loss equivalent to the reduced light quantity. This reflected light functions as the return light quantity with about 5-10% width. Thus it is possible to suppress the noise component of the laser 1 serving as a light source. This omits the control processing of the return light quantity and improves greatly the productivity.

Title: Lithium secondary cell with carbon fiber constituting positive and negative electrode
Inventor: SEKINO AKIZO
IPC: H01M10/0525
Filed: 1985-10-30
Abstract: PURPOSE:To lengthen the life of a secondary lithium cell, heighten the energy efficiency thereof and reduce the weight thereof, by using carbon fibers of high degree of graphitization to constitute a positive and a negative electrodes, and using one or both of LiI and LiBr as an electrolyte. CONSTITUTION:A negative electrode is made of carbon fibers of high degree of graphitization instead of metallic lithium. A positive electrode is also made of carbon fibers. A least one of LiI and LiBr is used as an electrolyte. An organic nonaqueous solvent is used as an electrolytic solution. A secondary lithium cell comprises the negative and the positive electrodes, the electrolyte and the electrolytic solution. Since the negative electrode is made of the carbon fibers, lithium atoms having undergone intercalation are taken into the carboni fibers so that the lithium atoms thereafter do not come into contact with the electrolytic solution and hot have the opportunity to react therewith. As a result, the life of the secondary lithium cell is made much longer than that of a secondary lithium cell with a negative electrode of metallic lithium although the energy efficiency of the former cell drops slightly.
