Title: Thin film evaporating type heat exchanger
Inventor: NAKAJIMA TADAKATSU
IPC: F28F1/12
Filed: 1982-05-26
Abstract: PURPOSE:To permit to improve a performance by a method wherein liquid refrigerant is dropped freely from the upper side of the group of vertical heat transmitting tubes so as to form liquid films on the surfaces of the heat transmitting tubes and the heat transmission is effected by the evaporation thereof in the shell tube type thin film evaporating system heat exchanger. CONSTITUTION:The liquid refrigerant enters into a liquid refrigerant header 20 from entrances 22, 23 and flows into liquid refrigerant distributing members 17, 18 through flowout ports 24, 25, thereafter, is flowed down along the surfaces of the heat transmitting tubes 12 and forms the liquid films 29. The liquid film 29 is evaporated by receiving heat from liquid 14 flowing in the heat transmitting tube 12 while the vapor thereof flows out of an vapor outlet port 26 through an eliminator 28 and the liquid refrigerant, which is not vaporized yet, flows out of an outlet port 27. The liquid 14, which has effected the heat exchange between the liquid film refrigerant, is taken out of the vessel through a lower header 16. Thus, the structure of the main frame of the heat exchanger may be simplified, while the size and weight thereof may be reduced and the heat transmitting performance thereof may be improved remarkably.

IPC: H04L7/06
Filed: 1980-06-27
Abstract: PURPOSE:To perform stable transmission and reception by obtaining a synchronizing signal, synchronizing with a received data signal, from the received signal regardless of the state of a transmitted data signal. CONSTITUTION:When a switch 3 is controlled by a data signal, the output of the switch 3 is made into an FSK signal, frequency-modulated into a frequency (n) or (m) times the oscillation frequency of a quartz oscillator 4 synchronizing with a data pulse signal, and then sent to a reception side. The received FSK signal is demodulated by a frequency discriminator 10 into data signal pulses, which are outputted 12 via a buffer amplifier 11. Part of the FSK signal is brought under switch control by the output of the discriminator 10, so the output frequency of a switch 15 is held equal to that of the oscillator 4. Consequently, the output frequency of a voltage-controlled oscillator 17 is equalized to that of the oscillator 4 and the output of the oscillator 17 is outputted from a terminal 20 synchronizing with a data signal outputted from a buffer amplifier 19 to a terminal 12.
