IPC: B60T8/26
Filed: 1977-10-06
Abstract: PURPOSE: To make appropriate the distribution of hydraulic pressure to the front and rear brakes, by installing between a master cylinder and rear wheel brakes a hydraulic control valve unit consisting of an inertial cut-off valve and a stepped piston.  
     CONSTITUTION: The hydraulic control valve unit 100 having a casing 20, wherein a ball 21, the cut-off valve 23 and the stepped piston 28 are arranged, is installed between the tandem master cylinder 11 and the rear wheel brakes 14. When a predetermined deceleration occurs in braking operation of unloaded vehicle, the ball 21 rolls and a valve body 26 comes into contact with an oblique inside wall 24a against a spring 27 to cut off the master cylinder pressure supply to the rear wheel brades 14. As a result, excessive braking force is not caused, thereby preventing the wheels from being locked. As for loaded vehicle, the stepped piston 28 moves left and the ball 21 is held from rolling. Therefore, the cut-off valve 23 is kept open, thereby supplying sufficient braking pressure to the rear wheel brakes 14

Abstract: PURPOSE:To measure quickly and easily specific antibodies of syphilis, virus, etc. and to enable the identification of the initial and middle stages of infection, and cure, by bringing a twice diluted soln. of a specimen into reaction then bringing the same into reaction with a carrier sensitized with an antigen. CONSTITUTION:The specimen serum is brought into reaction with red blood corpuscles sensitized with a rabbit anti-human IgM antibody (AM-RBC), red blood corpuscles sensitized with a rabbit anti-human IgA antibody (AA-RBC) and red blood corpuscles sensitized with a rabbit anti-human IgG (AG-RBC) in the case of, for example, syphilis in detection of the specific antibody of virus of syphilis, rubella, etc. The respective sensitized red blood corpuscles and the supernatant liquid are separated after the above- mentioned reaction, then again the sensitized red blood corpuscles are suspended in a physiological salt soln. and are brought into reaction with the red blood corpuscles sensitized with a syphilis antigen (TP-RBC). The presence of clotting is indicative of the presence of an antibody in the serum to be detected. The antibody value in the serum is known from the max. dilution times at which the clogging arises. Since the presence or absence of the clotting is known from the kinds of the red blood corpuscles sensitized with the antibody in the initial stage and middle stage of infection and the cure stage, the diagnosis is surely made possible.
