IPC: B29C65/34
Filed: 1990-11-29
Abstract: PURPOSE: To uniformize the heating of a member to be heated and to stop the heating thereof at the time of the appearance of the optimum welding condition by cutting off the supply of electricity to the resistor arranged in plastic constituting the member to be heated at when the short-circuit of a resistance wire by the welding of an insulating coating layer is detected. CONSTITUTION: A weldable joint 1 is formed by fitting the end parts of cylindrical pipes 6, 8 of a heat-meltable resin in the central opening 4 of a connection sleeve 2 of a heat-meltable resin. An electric heating type resistor 10 is provided in a sleeve 2 and is provided with crossing points shown by 11a, 11b, 11c by one conductor and coated with an electrical insulating layer 13. The melting temp. of this layer is set between the lowest temp. higher than the melting temp. of plastic and the highest temp. lower than temp. receiving thermal destruction of a member. Therefore, when this layer is melted, at least a part of the crossing points of the resistor generates a short-circuit. Since the conductor is connected to a current measuring means 21, the first short-circuit can be immediately detected.  Therefore, the moment a short- circuit is generated these changes are detected and a command for cutting off a current is issued by opening a circuit 23.

Abstract: PURPOSE:To ensure the stable control in a wide range by having the operations to turn the result of comparison carried out between the received power and the prescribed reference power into the numerial data and to smooth this data and controlling the gain of an amplifier based on the result of those operations. CONSTITUTION:The received signals are turned into the voice/video data through an HF amplifier 102, a frequency converter 103, a variable gain amplifier 104 and a demodulator 105. A power detector 105 generates toe numerical received power signals by an A/D converter and a digital square unit and sends these signals to a control signal generation circuit 107. The circuit 107 turns the value of the received power signals into the frequency by a clock against the prescribed reference received power and integrates the frequency. The upper and lower stage threshold values are set to the integration value, and the gain of the maplifier 104 is reduced or increased when it exceeds both threshold values. For this purpose, a gain control signal is produced. Thus the signals are processed in a wide dynamic range with no use of a logarithm converter, a log amplifier, etc., and in a simple constitution.
