Filed: 1983-05-06
Abstract: PURPOSE:To detect a relative speed with high precision even when a transmit and a receive wave vary in inclination by detecting the difference in frequency between receive signals of two receivers installed at different positions. CONSTITUTION:A transmitter 11 transmits an ultrasonic transmit wave at an inclination theta to in front of a vehicle, and the receivers 12 and 13 are installed almost at the same position with and in front of the transmitter 11, respectively. Then, reflected ultrasonic waves from a road surface G, i.e. an ultrasonic wave traveling at the inclination theta to in front of the vehicle and an ultrasonic wave traveling at the inclination theta to behind the vehicle are received by the receivers 12 and 13.

Abstract: PURPOSE:To prevent excessive drop of a cooled water outlet temperature or the freezing of a refrigerant solution by successively opening and closing under control a first on/off valve and a second on/off valve, according to an outlet cooled water temperature of a vaporizer during hot water main control. CONSTITUTION:When a cooled water outlet temperature drops even after cooled water load is subjected to sharp drop and continuous its condition continuously and refrigerant ceases to flow from a high temperature generator 1 to a condenser 3, a first on/off valve 33 is opened so that the refrigerant solution of the condenser 3 may flow to an absorber 5 where an absorbing solution is diluted. Moreover, when the cooled water outlet temperature drops, a second on/off valve 34 is opened so that a large amount of refrigerant solution of a vaporizer 4 may flow to the absorber 5 where a large amount of absorbing solution is diluted. At the same time, a spray volume of refrigerant in the vaporizer 4 is decreased, thereby definitely avoiding an excessive drop in the cooled water outlet temperature and a rise in the concentration of absorbing solution. The cooling capacity vary with the cooled water outlet temperature which makes it possible to stabilize the cooled water outlet temperature.
