Title: Heat transferring pipe for heat exchanger
Inventor: SHIMOOKE TAKANORI
IPC: F22B1/06
Filed: 1990-09-05
Abstract: PURPOSE:To shorten the leakage sensing time and reduce the probability of a concurrent breakage of an inner pipe and an outer pipe by a method wherein a spacing formed between the inner pipe and the outer pipe is partitioned by partitioning plates at predetermined intervals in an axial direction of the pipes, both ends of the defined segments are provided with each of the vacant spacings and then a tubular partition wall pipe is disposed. CONSTITUTION:A spacing having a doughnut-shaped section is formed between an inner pipe 1 and an outer pipe 2. The spacing is partitioned by partitioning plates 5 at predetermined intervals in a axial direction of the pipe. Both ends in the defined segments are provided with vacant spacings and a tubular partition wall pipes 3 is disposed in it. A primary high temperature fluid flows outside a heat transferring pipe, the secondary low temperature fluid flows inside the heat transferring tube. Thermal siphon working fluid boils at an inner of the outer tube 2 of the heat transferring tube. The working fluid is condensed at an outer surface of an inner pipe 1 of the heat transferring pipe, thereby the heat is transmitted from the high temperature fluid of the primary system to the low temperature fluid of the secondary system. The thermal siphon double-pipe type heat transferring tube shows a short detecting time in the event that a leakage occurs in either the inner pipe or the outer pipe and then the probability of concurrent breakage of the inner pipe and outer pipe is reduced.

Title: Radio transmitter
Inventor: KAMIHARASHI MITSUAKI
IPC: H04B1/16
Filed: 1984-11-06
Abstract: PURPOSE:To attain low power consumption by providing a power supply control section detecting the closing of a transmission switch and starting supply of power voltage, and a signal processing section detecting the supplied power voltage and outputting a power supply consecution signal to the power supply control section. CONSTITUTION:A signal (a) representing that the transmission switch 2 is turned on is fed to the power supply control section 3. The power supply control section 3 uses the signal (a) as a trigger to supply a battery voltage (c) to a signal processing section 4 and a transmission section 5. The signal processing section 4 inputs the battery voltage (c) to start the operation and outputs the power supply consecution signal (b) to the power supply control section 3 before the signal (a) is reset. The power supply control section 3 uses again the signal (b) as a trigger input and supplies the battery voltage (c) continuously. The signal processing section 4 completing the transmission resets the signal (b). Thus, the power supply control section 3 resets the battery voltage (c).

Title: Bootstrap circuit
Inventor: OOYAMA AKIHIRO
IPC: H03F3/30
Filed: 1984-11-08
Abstract: PURPOSE:To improve the power supply voltage utilizing efficiency and to prevent waveform distortion at a low frequency region by connecting a semiconductor element of diode operation and a resistive element in parallel between a bootstrap terminal and a power terminal. CONSTITUTION:A diode 4 and a resistor 9 are connected in parallel between the bootstrap terminal 3 of an amplifier 1 and the power terminal 8. The resistance of the resistor 9 is selected so that the voltage across the resistor 9 is smaller than the forward voltage of the diode 4. Thus, the voltage at the terminal 3 depends on the voltage drop across the resistor 9 because the diode 4 is turned off. Since the voltage drop by the resistor 9 is small without signal input, the amplifier 1 is operated at a low power supply voltage. Further, when a signal is inputted, the diode 4 is conductive and a bootstrap capacitor 5 is charged rapidly. Thus, no missing is caused in the output waveform. Thus, the power voltage utilizing efficiency is improved and waveform distortion at a low frequency region is avoided.
