Abstract: PURPOSE: To obtain a hydraulic tappet cylinder of joined type of superior pitching resistance and good workability by casting a plate member separately from a forged cylinder body, and preheating the fayed surfaces of both with the arc then switching to regular welding.  
     CONSTITUTION: A cylinder body 12 is formed by forging by using a general structural cast steel material such as low carbon steel. A plate member 16 is cast by using cast iron of superior seizure resistance and abrasion resistance. The body 12 is set to a chuck 19, and the member 16 to a pressing chuck 20 in such a manner that these are forced to contact 17 each other by being energized with the latter chuck. Thence, the entire circumference of the fayed surfaces 17 is perheated by arc heat with a torch 24 by using a high frequency pulse arc welding machine 23. Thence, the machine 23 is switched to regular welding, and the entire circumference of the fayed surfaces 17 is subjected to regular welding by melting a stainless steel 309 welding wire 26, whereby a joined tappet cylinder 11 is formed.

Title: Braking method and device for vehicle
Inventor: NAKADA MASARU
IPC: B60K23/08
Filed: 1986-05-14
Abstract: PURPOSE:To shorten the braking distance by applying brakes through changing- over from two-wheel to four-wheel drive at the time of brake application during two-wheel drive. CONSTITUTION:If a brake pedal 9 is stamped during two-wheel drive operation, it is sensed by a sensor switch 29, and a hydraulic clutch 13 is connected through a solenoid valve 26. This causes changing-over into four-wheel drive condition, wherein the power is transmitted to the front wheels 4. Accordingly if the right and left brake pedals 9 are stamped simultaneously to actuate a brake 18, the braking force is applied not only to the rear wheels 5 but also to front 4 to cause stop of rotations of all four wheels. This increases frictional resistance with the surface course of road to lead to shortening of the braking distance till attainment of full stop.
