Abstract: PURPOSE:To prevent excessive cooling and shorten the time of warming-up, by enabling the drive of a water pump independently of the rotation of an engine to reduce the water supply of the pump when the temperature of the engine is below a set level. CONSTITUTION:A water pump 7 is installed in a cooling water passage 2 extending through a water jacket provided in the cylinder block 4 and cylinder head 5 of an engine 1. The pump 7 is driven with a belt 10 by an electric motor 11, the drive of which is regulated by a controller 9 on the basis of the output of a temperature sensor 12 which detects the temperature of the engine 1. When the temperature of the engine is not higher than a set level, the rotational frequency of the motor 11 is controlled to keep that of the pump 7 at a prescribed low value. When the temperature of the engine 1 is higher than the set level, the rotational frequency of the electric motor 11 is controlled to equalize that of the pump to a prescribed high value. According to this constitution, the engine 1 is prevented from being excessively cooled when its temperature is low.

IPC: G01C19/42
Filed: 1992-03-03
Abstract: PURPOSE: To measure a rotation ratio of vehicle even on a road with indentation by high-pass filtering each rotation ratio signal occurring in response to the output signal from a gyro device, and low-pass filtering each rotation ratio signal occurring in response to the output signal from a route sensor. CONSTITUTION: In the process of high-pass filtering a rotation ratio signal 18 obtained by a gyro device 12 is made to pass through a high-pass filter 20 which suppressed such rotation ratio signal as the magnitude of drift frequency of the gyro device. In the process of law-pass filtering, a rotation ratio signal 22 obtained from a route sensor 10 is made to pass through a low-pass filer 24 which only allows a rotation ratio signal 22' occurring during normal driving of a vehicle 14 with no fault to pass. The output signal of car rotation ratios 18' and 22', having passed through a filter, are combined to an addition amplifier 28. By suppression of sensor fault, an accurate vehicle rotation ratio is measured against a specified route, with the rotation ratio signal 18 free from drift measuring a specified route of a vehicle, while, for example, fault due to indentation is present.

Abstract: PROBLEM TO BE SOLVED: To accurately measure the degree of vacuum without withdrawing outside a lead wire and the like, by calculating the degree of vacuum by a calculation means that is buried into a measurement object and generating a vibration corresponding to the degree of vacuum being calculated. SOLUTION: A vacuum meter 29 is buried into urethane 27 that is a core material inside a vacuum panel 21 but a signal line is not led out of the panel 21. Therefore, the sealing conditions of films 28a and 28b of the panel 21 where the vacuum meter is buried and a vacuum panel where it is not buried are equal. A mechanical vibration is transmitted from a vibration detection sensor 22 to a signal-processing circuit 23 as a voltage signal Vf, where the inner degree of vacuum of the panel 21 is measured from the signal Vf. The sensor 22 converts the mechanical vibration of a frequency fp to a sine wave voltage signal Vf, which is outputted to the circuit 23. The circuit 23 calculates the frequency fp of the sine wave signal Vf outputted from the sensor 22 and calculates the degree of vacuum from the relationship between the frequency fp and the degree of vacuum.
