Title: Transistor relay circuit
Inventor: INOUE KIYOKAZU
IPC: H03K17/567
Filed: 1981-05-14
Abstract: PURPOSE:To decrease the driving current at the application of switch, by connecting a MOS transistor (TR) in series to a base circuit of the input stage TR of switching TRs in Darlington connection. CONSTITUTION:A power supply is connected to a terminal C via a load and a switch application signal is applied to a terminal B, then a large current flows at the application according to the characteristic of the load. Then, a collector- to-base voltage of a TR2 is increased, an MOS TR is conducted and supplies a  current to the base of a TR10. Thus, a large current can be supplied to a load with a circuit of Darlington connection with the TRs 10 and 2 and the base current of the TR10 can be small. When the current to the load is decreased at a  steady state, the collector potential of the TR2 drops, a TR11 is nonconductive,  the TR10 also turns off and the power consumption of the switch circuit is decreased.

IPC: F24F11/02
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To shorten the time of defrosting by judging the quantity of frosting, and enabling adaptable defrosting. SOLUTION: At heating operation, an outdoor controller 11 detects the temperature of outdoor heat exchange by the signal from an outdoor heat exchange temperature detector 6 in every specified time, and stores the present and last outdoor heat exchange temperatures on one hand, and when the present temperature reaches the defrosting operation value, it detects the present discharge temperature with the signal from a discharge temperature detector 13, and also computes the temperature difference between outdoor heat exchange temperatures detected this time and last time, and performs defrosting, according to a table 11a, on the basis of the discharge temperature and the temperature difference.  The defrosting time by a hot gas bypass system is shortened, judging that the quantity of frosting is more, the lower the discharge temperature is and the larger the temperature is, and then, it is switched to a reverse system to quicken the finish of the defrosting. The time of defrosting by only the hot gas bypass system or the time of defrosting by this system is elongated, judging that the quantity of frosting is less, the higher the temperature of the discharge tube is and the smaller the temperature difference is, and then it is switched to the reverse system.
