Filed: 1980-08-09
Abstract: PURPOSE:To make accurate control possible without hysteresis phenomenon by adjusting a signal fed to a solenoid coil so as to be ''0'' in every reduction of the signal. CONSTITUTION:During the period when an output A generated from an electric signal generating circuit 1 according to an output from the temperature detector F5 of a regregerator F is decreasing, the output of an amplifier 9 equipped with gate means is reduced to ''0'' only for the period of one pulse from a one shot pulse generating circuit 7 in every time the reduction value exceeds standard value S and the remaining megnetism of a solenoid valve F3 disappears, keeping the opening extent of the valve F3 at the opening extent on the going line of a hysteresis curve. While the output A is increasing, the output D is continuously generated without reduction to ''0''. Thus, the opening extent 3 of the valve F3 can be accurately controlled by the output information of the temperature detector F5.

IPC: G01N1/00
Filed: 1990-04-27
Abstract: PURPOSE:To extract an analytical solution from a selected optional position without executing cutting, wax coating, and so on. CONSTITUTION:The analytical position of a sample 1 to be analyzed is selected by masks 2, 3. An extracting solution 8 is extracted only from the apertures 6, 7 of the corrosion-resistant and water-proof masks 2, 3.

Filed: 1993-04-12
Abstract: PURPOSE:To provide a proper braking feeling according to a road surface state by changing the wheel speed judging reference value for antiskid control end judgment smaller as a detected surface state increasingly tends to cause slips. CONSTITUTION:Wheel speeds detected by wheel speed sensors 26-29 are inputted to an ECU 24, which operates valve units 20-23 on the basis of the wheel speeds and periodically increase and decrease the braking pressures to perform antiskid control. When the detected wheel speeds are smaller than a prescribed judgment standard value, the antiskid control is ended. On the other hand, the highest wheel speed of the detected wheel speeds is taken as a pseudo car body speed, the car body speed change quantity is further determined, and the surface frictional coefficient is determined by use of a frictional coefficient table. The tendency of wheel slip is judged by use of this surface frictional coefficient, and when the slip tendency is judged large, the wheel speed judgment reference value is changed to a smaller value.
