Patent JP-H03271050-A (JP)
Title: Atmosphericpressure type servo unit
Inventor: KAMISHIRO SHINJI
IPC: B60T13/57
Filed: 1990-03-20
Abstract: PURPOSE:To improve the extent of responsiveness at time of sudden braking by installing a bypass passage, interconnecting the inner part of a valve body to the atmospheric side when an input rod is relatively displaced frontward as far as the specified value to the valve body, in space between a filter and/or silencer and the input rod. CONSTITUTION:When a brake pedal is rapidly operated and an input rod 48 goes forward, a plunger 49 moves forward and thereby a valve seat 54 separates from a valve body 55 which is thus opened. Then, a cylindrical member 69 moves forward as far as the specified value to a silencer 67 and notch 70 (bypass passage) comes to a state of being opened, thus the atmosphere is inhaled via the notch 70 after passing through a filter 66. Then, the atmosphere passes through a breather valve 60 and a passage 58 and is taken into a rear transfer chamber 43, further the atmosphere passes through a passage 59 and is taken into a front transformer chamber 41 as well. At this time, since the atmosphere is fed to the side of the breather valve 60 via the notch 70 without receiving any inlet resistance due to the passing of the silencer 67, a large quantity of air is quickly conducted into these transformer chamber 41, 43, thus the extent of responsiveness is improved.

Abstract: PURPOSE:To improve joint strength by disposing a low carbon alloy steel plate contg. specific weight % of Ti, V, etc. to a cladding metal side and Ni plate to a base metal steel plate side to form a clad stock, then subjecting the stock to rolling and press welding at a specific temp. CONSTITUTION:The clad stock is formed by disposing the low carbon steel plate 3 contg. 1 or >=2 kinds among 0.01-5.0% Ti, 0.05-10% Nb, 0.01-20% V, and 0.05-10% Mo and contg. <=0.05% C to the cladding metal 4 side and disposing the Ni plate 2 to the base metal 1 side at the time of forming a clad steel by hot rolling a Ti plate 4 and the base metal steel plate 1. The cladding metal 4 and the low carbon steel plate 3 are maintained in a non- oxidative atmosphere and is subjected to rolling and press welding at 700-870 deg.C. The diffusion and intrusion of carbon from the base metal are prevented and the formation of an intermetallic compd. at the boundary face is prevented by the above-mentioned method and therefore, the joint strength of the clad is improved.
