Abstract: A piezoelectric ceramic device is heated so that the temperature is increased to a temperature in the vicinity of the maximum temperature at which the device, when the temperature is returned to ordinary temperature, is returned to substantially the same piezoelectric characteristic before heating. In the state that the piezoelectric ceramic device is heated, and the temperature is increased, at least one of the piezoelectric phase characteristic and the impedance characteristic of the piezoelectric ceramic device is measured. The measurement is compared with a standard characteristic, whereby an internal defect of the piezoelectric ceramic device is detected, based on results of the comparison.

Abstract: A method for accurately measuring the insulation resistance of a capacitor while reducing time taken for the measurement. To this end, a current calculation equation is first obtained based on an equivalent circuit of a capacitor; then, the calculation equation is modified or corrected based on the degree of coincidence between an actually measured current value m(t) and a calculated current value i(t), the former being within a charge-up region of a dielectric polarization component upon initial application of a voltage; next, the current value at a time point of chargeup termination is predicted or estimated by use of this modified calculation equation.

Abstract: An automotive air conditioning system has refrigeration devices, heating devices and a single chip microcomputer. The refrigeration devices include a variable displacement refrigeration compressor drivingly connectable by an electromagnetic clutch to an automotive engine and a refrigerant evaporator disposed in an air duct, through which air is caused to flow by a blower. The heating devices include a heater core disposed downstream of the refrigerant evaporator, through which heated air is caused to flow, and an air mixing damper which regulates the quantity of air to be introduced into the heater core. A condition relating to the air conditioning operation such as the temperature of the vehicle is detected by a sensor. The microcomputer receives the signals from the sensor, calculates a required injection temperature, compares the required injection temperature and a preset standard temperature, a lower standard temperature and a higher standard temperature and produces operating signals.

Abstract: A portion of an air-conditioning unit is divided into two so as to provide first and second air-mixing chambers each following first and second temperature adjustment mechanisms. The temperature of air in the first chamber is controlled independently of the temperature of air in the second chamber, while the first chamber communicates with a first group of air-conditioning zone or zones and the second chamber communicates with a second group of remaining zone or zones. Thus, the temperature of air fed to the first group can be controlled in a manner different from the temperature of air fed to the second group. A plurality of distributing valves are provided at air discharging outlets communicating with the first or second chambers, and the opening degree of each damper may be controlled so that air distribution amount may be controlled.
