Abstract: PURPOSE:To assure an ohmic contact between a barrier metal and a P type diffusion layer by ion-implanting a P type impurity into the P type diffusion layer and forming a highly concentrated diffusion layer only on the surface of the P type diffusion layer. CONSTITUTION:An N type diffusion layer 14, a P type diffusion layer 15, and an interlayer insulating film 20 are formed on a silicon substrate 11, and contact holes 21, 22 are formed through the interlayer insulating film. After the contact hole 22 is formed, a resist layer 23 is formed only on the P type diffusion layer 15, and the P type diffusion layer 15 is ion-implanted with a P type impurity using a pattern of the resist layer 23 as a mask to increase surface concentration of the P type diffusion layer 15 for formation of a high concentration diffusion layer 24. Accordingly, a barrier metal process is usable as it is as a conventional process, without influence thereof onto a P type transistor. Thus, an ohmic contact is assured between the barrier metal and the P type diffusion layer.

Title: Fade-out circuit
Inventor: UKITA SHINJI
IPC: H04N5/30
Filed: 1984-07-10
Abstract: PURPOSE:To realize fade-out and to improve its operability by closing a diaphragm mechanism with the operation of a fade-out volume and limiting the operation of an AGC circuit. CONSTITUTION:In applying fade-out by AGC operation, a fade-out volume (VF) is turned to decrease a reference voltage. When the reference voltage is decreased, the diaphragm mechanism is closed gradually. On the other hand, the reference voltage is inputted to a window comparator 8 constituting a part of an AGC limit circuit and when the reference voltage reaches a prescribed level or below, the comparator output is inputted to a switching circuit 6. The circuit 6 applies a constant voltage set by the 2nd variable resistor VR2 in place of the 2nd peak detection output at the generation of comparator output to fix the amplifier gain of the AGC circuit 4. Thus, the diaphragm mechanism is closed by the turning of the fade-out volume VF and the AGC control voltage is fixed.

Abstract: PURPOSE:To make the effective use of the cold air accumulating effect of an indoor heat exchanger and to control the re-evaporation of water from the heat exchanger by a method wherein when a compressor is stopped at the time of cooling operation, an indoor side fan is stopped after a delay of a predetermined time. CONSTITUTION:When an operation switch 9 is turned ON at the time of cooling operation, the compressor 1, an outdoor side fan 3 and the indoor side fan 6 are started and the air around the indoor heat exchanger 5 is cooled by the evaporation of a coolant passing through the heat exchanger to thereby cool the interior of the room. Thus, when the room temperature drops to a level at which the compressor 1 and the outdoor side fan 3 should be stopped, an indoor thermostat 7 detects it whereupon a relay 11 is opened by the operation of a controller 12 to stop the compressor 1 and the fan 3. In this case, the indoor side fan 6 is not stopped at once but is continued to operate for a suitable period of time or a time proportional to the length of time for which the continuous operation of the compressor 1 has been made.
