摘要： A circuit which selects a supply voltage from a plurality of voltage supplies is presented. The circuit includes a first transistor configured to select a first voltage supply, a second transistor configured to select a second voltage supply, a first parasitic current inhibitor coupled the first transistor, the first voltage supply, and the second voltage supply, where the first parasitic current inhibitor automatically utilizes the voltage supply providing the highest voltage for preventing a substrate current from flowing through a bulk node of the first transistor, and a second parasitic current inhibitor coupled the second transistor, the first voltage supply, and the second voltage supply, where the second parasitic current inhibitor automatically utilizes the voltage supply providing the highest voltage for preventing a substrate current from flowing through a bulk node of the second transistor.

摘要： A power-on reset circuit is provided for generating a power-on reset signal for sequential logics or memory devices as a power supply potential is applied initially. The power-on reset circuit is provided in the same chip as the sequential logics, and generates the signal after an adjustable time interval. The power-on reset circuit includes an oscillator for generating a clock signal, and a counter for counting pulses of the clock signal from when the power supply potential is applied. The time interval is adjusted by loading a preset data value in the counter, which thus outputs a CTR signal when the counted pulses become equal in number to the preset number. A combinational logic circuit resets the counter when the power supply potential is initially applied, and also generates a power-on reset signal when the counter outputs the CTR signal. The power on reset signal further disables the counter, so that the CTR signal is maintained.

摘要： Disclosed is a heat exchanger for an indoor unit of an air conditioner being easier to make and having an improved efficiency of heat exchange by enlarging an area of the heat exchanger, which makes contact with air in a room. The heat exchanger for the indoor unit of the air conditioner comprises a first fin assembly for absorbing a heat from air in a room, a second fin assembly which is adjacent to an upper portion of the first fin assembly and spaced by a predetermined distance with respect to the first fin assembly, for absorbing a heat from air in the room, a plurality of refrigerant pipes which extend through the first fin assembly and the second fin assembly, for supplying a pathway for refrigerant, and a connecting member for connecting the first fin assembly and the second fin assembly with each other so that the second fin assembly is secured to the first fin assembly. The first fin assembly and the second fin assembly are made separately and connected by the connecting member so as to enlarge an area of heat exchange, thereby improving an efficiency of heat exchange.
