Abstract: PURPOSE:To obtain a non-contact type flowmeter free from maintenance etc., by determining change of flow by irradiating into the liquid surface a light beam of strong directional property, such as a laser beam and change of received magnitude of the reflected beam. CONSTITUTION:When a liquid level at the max. allowable flow is assumed to be S0, a light receiving apparatus 7 is so arranged that, when the level reaches S0, a reflected laser beam L' with the beam width d0 becomes wholly incident to a light receiving unit 7'. Namely, at the liquid level of S0, the laser beam reflected at the part identified with a symbol A0 becomes wholly incident to the light receiving unit 7'. However, when the liquid level drops down to S1 and further to S2, only the reflected laser beam (beam corresponding to beam widths d1, d2 respectively) from the part identified with symbols A1 and A2 becomes incident to the light receiving unit 7'.

Filed: 1982-06-30
Abstract: PURPOSE:To provide a fire checking system with a reduced load of a processor by discriminating whether a value reaches as prescribed which is connected at each check timing to indicate the operating condition of a driver in a magnet. CONSTITUTION:A sampling check SCLK corresponding to a sampling period (e) is applied to a counter 4 to check for the output of a fire checking circuit 1, namely, whether an operation amplifier 7 outputs VL or not. When an abnormality occurs, the output of the fire checking circuit 1 always gives VL, which is transmitted to an inverter 5 via an input port 2 to be applied to the counter 4. The counter 4 counts and outputs the sampling clock SCLK to a comparator 6. When a character pulse CP is transmitted to the comparator 6, the comparator 6 compares the current countings with the threshold H and generates an alarm of abnormality when they are larger than the value H.

Title: Car locking preventive brake system
Inventor: ARAN RESURII HARISU
IPC: B60T8/1761
Filed: 1989-05-08
Abstract: PURPOSE: To maintain the stability of a vehicle by controlling a rear axle anti- lock system to be temporarily de-sensitized just before it would be expected, on the basis of speed and wheel-base, to reach a road bump upon detection of the same bump by a front axle. CONSTITUTION: A control circuit 16 monitors the rate of change of the frequency of a signal inputted by a wheel speed transducer 17. When the change of rate exceeds a first threshold during braking and the wheel speed is rapidly reduced, the control circuit 16 closes a valve 12 and interrupts the connection between a master cylinder 10 and a slave cylinder 11. Further, fluid is discharged from the slave cylinder 11 to a holding chamber 13 so that the pressure of the slave cylinder 11 is lowered. In this case, when a road bump is detected by a front axle during periods that anti-lock is not carried out, a rear axle anti-lock system is temporarily de-sensitized just before it would be expected, on the basis of speed and wheel-base, that the rear axle reach the same bump.
