Inventor: DOMAE MITSUHIRO
IPC: H03F1/52
Filed: 1986-04-21
Abstract: PURPOSE:To cut a demand, to reduce a calorific value, to improve profitability, and to miniaturize a structure, by controlling a power source voltage synchronizing with the presence/absence of a burst-shaped RF signal, and impressing a bias voltage on an amplifier only when the signal exists.

In other words, a transistor 22 is turned on or off by the control signal from the burst sending control circuit 21. Therefore, a transistor 9 is turned on or off. Consequently, since a transistor 8 goes to an on-state only when the RF signal exists, a current is permitted to flow on a field effect transistor 7, thereby accomplishing a function as the high output transistor amplifier 1.

Title: Semiconductor device
Inventor: YOSHIZAWA SHIGEYUKI
IPC: H01L27/082
Filed: 1982-05-31
Abstract: PURPOSE:To constitute a constant-current circuit without increasing an area of an element by making the impurity concentration profiles of the base regions of a plurality of bipolar transistors forming a logic circuit differ. CONSTITUTION:The impurity concentration of each base region A, B of the transistors TRA, TRB differs. Consequently, forward voltage VBE among the bases and emitters of the TRs can be controlled by changing the impurity concentration of the bases, and the TRs having different VBE characteristics can be formed in one semiconductor device in the same area. As a result, currents such as ones twice as much as reference currents can be flowed through load even when the junction areas of the bases and emitters of the TRA and the TRB are equal. Accordingly, the constant-current circuit can be constituted without increasing the area of the element.

Title: Indoor unit of air conditioner
Inventor: KURACHI MASAO
IPC: F24F1/00
Filed: 1986-04-22
Abstract: PURPOSE:To prevent short-circuiting from occurring and to reduce a temeperature difference between the upper part and lower part of a room there by to improve the comfortableness by providing an auxiliary blow-off port through which is blown off a primary side airstream sent from a blower to between a suction port and the blow-off port which are situated adjacent to each other. CONSTITUTION:An auxiliary air flowpath 7 in a drain pan and an auxiliary blow-off port 9 through which a low-temperature airstream of a primary side airstream of a heat exchanger, is provided between a suction port 3 and a blow-off port 6 which are situated adjacent to each other. Thus, it becomes possible to prevent short-circuiting in which a part of a blown off airstream is sucked up to the suction port 3 even when a downward blow-off is carried out during the space heating operation. Further, since a high-temperature airstream from the blow-off port 9 are mixed with each other to form a middle- temperature blown off sirstream, the specific gravity of air becomes slightly large, thus increasing the distance to reach downward and decreasing the distribution of the temperature at the upper part and the lower part within the room. Therefore, the comfortableness in the room is improved.
