Abstract: PURPOSE:To eliminate occurrence of abnormal noise at the time of actuating a brake pedal by providing a passage communicating the inlet side of a poppet valve element and the side of a piston to each other between the inner wall of a valve chest and a cup type member. CONSTITUTION:A cup type member 50 in a valve chest 30 of a member 11 forms a passage 55 for working liquid by a tunnel 58 with respective spaces 56, 57 and a bottom part 53 provided between a large diametral part 51 and a small diametral part 52 and the inner wall of the valve chest 30. Additionally, a cutout 48 is provided on an outer peripheral part 42 of a poppet valve element 40 provided in the cup type member 50, and a second passage is formed between it and the bottom part 53 of the cup type member 50. When a brake pedal is stepped on, a piston 20 moves, a seat part 45 of the poppet valve element 40 is seated on a valve seat 25 of the piston 20, flow of working liquid is stopped, and thereafter, seating and separation are repeated. In this case, the greater part of working liquid passes through the passage 55, and accordingly, the poppet valve element 40 is almost isolated from the flow of working liquid, and consequently, no abnormal noise due to oscillation is generated.

Abstract: PROBLEM TO BE SOLVED: To change an FeMn alloy film into a film hard to corrode and to prevent corrosion by laminating an FeMnN alloy layer on the FeMn alloy layer, and heat-treating it to form an antiferromagnetic layer. SOLUTION: A giant magnetoresistive effect element (GMR element) 1 is a spin valve layer composed of four layers of a first NiFe layer 3 to be a free layer, a Cu layer 4, a second NiFe layer 5 to be a pin layer, and an FeMnN layer 8 formed in order on an insulating substrate 2 made by coating a sheet of glass or ceramic, etc., 1-2mm thick and worked into a specular plane with an aluminum film by sputtering, etc. And nitrogen in an FeMnN layer 8 diffuses into an FeMn layer 6 by heat treatment, and the whole changes into an FeMnN layer 8 of an antiferromagnetic substance. But when the quantity of N is large its property as an antiferromagnetic substance becomes weak, and if the quantity is small, its rust prevention effect becomes weak.  Accordingly, the FeMnN layer 8 shows a large exchange interaction of the FeMn layer, and becomes a film having a high anti-corrosion resistance too in addition.

Filed: 1990-11-19
Abstract: PURPOSE:To quickly inform the abnormality of device to a monitor center by making the monitoring device itself independent of its control section so as to inform the abnormality to the monitor center at the time occurring the abnormality. CONSTITUTION:A WTD 13 watches the occurrence of abnormality in a monitoring device 3, and consists of the following components. A timer 17 acts independently of other components without being affected by runaway or the like of a MPU 8. A counter 20 counts a clock WDTCLK for WTD to be output from the timer 17. On the other hand, by a WTD-RST signal to be output from the MPU 8, counting is cleared. That is, the WTD-RST signal, if the MPU 8 is normal, is output, otherwise the signal is not output, thereby detecting the abnormality of the device 3. Further, when the abnormality is detected, the control section MPU 8 generates an interruption. In this way, the MPU 8 executes transmission to a monitor center 2 to inform the occurrence of abnormality in the device 3 to the center.
