Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To prevent atomized air at an indoor device from being blown-out or prevent dew formation at an indoor fan from being generated without being dependent on a humidity or a temperature in an indoor region. SOLUTION: When a cooling operation is started (S1), an indoor suction temperature S is detected by an indoor suction temperature sensor, an indoor suction humidity H is detected by an indoor suction humidity sensor and an indoor blowing-out temperature F is detected by an indoor blowing-out temperature sensor (S2). An air conditioning dew point R is calculated by an air conditioning dew point calculating means in reference to the indoor suction temperature S and the indoor suction humidity H (S3). The indoor blowing-out temperature F and the air conditioning dew point R are compared with each other by an indoor temperature comparing means (S4). If a result of comparison is R>=F, an operating frequency of the compressor is set to be less than 20Hz at a compressor frequency output section (S5).  Only when the indoor blowing-out temperature F reaches the air conditioning dew point R, a frequency of the compressor is changed to reduce a freezing capacity, increase an air blowing-out temperature and then the blowing-out of the atomization or dew formation of the indoor fan or the like is prevented.

Title: Negative feedback amplifier
Inventor: ITO TAKESHI
IPC: H03F3/30
Filed: 1991-02-28
Abstract: PURPOSE:To reduce an idling current of an output stage by adding a common base transistor(TR) of an idling current and feedback input circuit to an input stage so as to set a feedback resistance value high. CONSTITUTION:When a voltage at an input terminal 11 is decreased, a collector current of a TR Q11 is decreased, a base current is increased and then a collector voltage is reduced. When the voltage is lower than a base voltage V3 of a TR Q17, a limiter diode CR11 is conductive and an idling current from a voltage +V1 flows to a collector of a TR Q13 through the CR11. Thus, the idling current flowing to the TR Q13 is reduced and an output current of the input stage is reduced. As a result, a base current of the TR Q13 is reduced resulting in reducing the collector current and preventing saturation. Since NPN TRs Q13, Q13 are operated without saturation even at a large amplitude output, deterioration in a fast response is prevented.

Abstract: PURPOSE: To carry out a coil inspection with no problem by selecting a capacitance of a series oscillation circuit, setting a resonance frequency within a range where the maximum value of a coil is obtained. CONSTITUTION: To a sample coil (test piece) 1, a capacitor 5 of capacitance C is connected in series.
