Abstract: PURPOSE:To obtain heat exchanger cores of a long life in the stage of brazing liquid  flow pipes using a noncorrosive flux and cooling fins in a furnace, by forming Zn diffusion layers that prevent pitting on the outside surfaces of the liquid flow pipes. CONSTITUTION:Liquid flow pipes 2 of an Al material A1050 and cooling fins 3 of core  and skin materials of the same A3003, A4045 are used. Zn-diffusion layers 5 of >=50mu  diffusion depth and 2.5-10% concns. of surface Zn are carried out by plating or the  like on the outside surfaces of the pipes 2. Many of the pipes 2 and the fins 3 are alternately superposed, seat plates 4, 4' are provided at both ends and these are tentatively assembled. These are subjected to a flux treatment wherein they are immersed  in an aq. flux soln. of KAlF4-K3AlF6, after which they are heated in a furnace, whereby all the elements are brazed to each other. Then, the layers 5 act as sacrifice electrodes and since the corrosion of the core materials takes place after the entire part of  the layers 5 is sacrificially corroded, a longer life is provided. If the diffusion depth of  the layers 5 is insufficient, defective brazing, etc. will result, and said layers are too  thin for the sacrifice corrosion layers. If the concn. of Zn is below the lower limit,  there is a problem in corrosion resistance on account of electrolytic corrosion during brazing and in excess of the upper limit, corrosion resistance is not improved.

Title: Brake of electric car
Inventor: TAICHI TOSHIO
IPC: B60T8/00
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To improve brake feeling by keeping a communicating state, until an input hydraulic pressure becomes a value for shortening the dead stroke of the other hydraulic brake, and becomes a second value equal to or larger than a first value. SOLUTION: The hydraulic pressure of a master cylinder exceed the electromagnetic force of a proportional solenoid 31Z, and a plunger piston 311 moves, and a stroke valve opening and closing part Vs closes and a poppet valve opening and closing part Vp opens. As a result of this, the input side of a hydraulic pressure control valve 31 communicates with its output side, and the pressure of each wheel cylinder on a front wheel side and the hydraulic pressure of the master cylinder rise at the same rate. The pressure of each wheel cylinder on the rear wheel side rises at the same rate as the hydraulic pressure of the master cylinder, through a check valve after a point where the front-wheel side wheel cylinder pressure becomes equal to the rear- wheel side wheel cylinder pressure. Accordingly, a current value given from an ECU is reduced or increased according to the variation of a regenerative braking force, and it becomes possible to secure a pedal stroke corresponding to the variation of the regenerative braking force, and to obtain excellent brake feeling always.
