Title: Booster ratio controller for hydraulic vacuum servo
Inventor: INOUE HIDEFUMI
IPC: B60T11/20
Filed: 1984-08-18
Abstract: PURPOSE:To make a booster ratio alterable at will, by forming a second power chamber with a step part of a stepped power piston and a housing, while feeding or discharging pressure oil to or from this power chamber. CONSTITUTION:A power piston 3 is formed into being stepped, and a second power chamber 51 is formed with its step part 50 and a housing 1. The second power chamber 51 is connected to a first power chamber 8 or a reservoir 41 via a flow passage selector valve 55. In a state of car loading, the power chamber 51 is interconnected to the reservoir 41 via the valve 55. Therefore, in time of braking, a pressure receiving area of the power piston 3 comes to A1 whereby a booster ratio is set to be large enough. And, in an empty car state, both these power chambers 8 and 51 are interconnected with each other by the valve 55. Accordingly, in time of braking, pressure oil in the power chamber 51 in addition to that in the power chamber 8 acts on the power piston so as to push it back. Therefore, the substantial pressure receiving area of the power piston 3 comes to A1-A2, thus the booster ratio is set to be small.

Filed: 1989-07-03
Abstract: PURPOSE:To reduce a memory capacity and to accommodate lots of lines by utilizing an associative storage memory provided a symbol string collation function on a common memory circuit and writing and storing the data to the idle area of the memory one after another. CONSTITUTION:Packets from all input lines 1, 2, 3 are subjected to time division multiplex by a multiplex circuit 4 and transferred to an associative storage memory circuit 14. When a write control circuit 12 collates the idle state to an idle/busy display bit and an idle address exists in the circuit 14, a coincident address is outputted. A readout control circuit 13 collates the destination information on the circuit 14 with the idle/busy display. When the coincidence is taken, since it means that a packet to be outputted to an output line 9 exists on the coincident address, the packet is read. Then the idle/busy display bit is rewritten from the busy state into the idle state and the write of the packet is implemented to the address.
