Title: Heat exchanger equipped with thawing apparatus for heat source fluid
Inventor: WATANABE NAOYUKI
IPC: F28D15/00
Filed: 1984-03-30
Abstract: PURPOSE:To prevent heat source fluid in tubes from freezing by a method wherein intermediate heat transfer medium is heated by providing a shell, in which the intermediate heat transfer medium is filled, a U-tube, through which liquefied gas is circulated, and tubes, which are arranged at the lower portion in the shell and through which heat source fluid is circulated. CONSTITUTION:Intermediate heat transfer mediums 3 and 3A are filled in the shell 1 of an intermediate heat transfer medium type heat exchanger A. Process side tubes 4 are immersed in the liquid of the intermediate heat transfer medium 3, while a U-tube 2, which is separate and independent from the tubes 4, is housed in the gas of the intermediate heat transfer medium 3A. Heat source fluid is supplied through a heat source fluid piping 9 into the tubes 4 and discharged outside through a heat source fluid piping 10. The intermediate heat transfer medium 3 comes to the boil by being given heat by the heat source fluid and ascends up to the upper portion in the shell 1 in the form of gas so as to turn into the intermediate heat transfer medium 3A in order to give heat to LNG supplied in the U-tube 2 through a processing piping 5 and to condense after the heat release and finally to drip down to the lower portion of the shell 1 in the form of the intermediate heat transfer medium 3. On the other hand, the LNG, which is vaporized by being given heat, is delivered through a processing piping 6 in the form of gas.

Title: Dynamic logic circuit and self-synchronous pipeline data path circuit
Inventor: FUJII KOJI
IPC: G11C11/407
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption by suppressing static leak current at the time of pre-charging or pre-discharging, which occupies the most part of a circuit operation, while the operation of a dynamic logic circuit is speeded up. SOLUTION: A MOS transistor of a logic circuit part, which is constituted of the MOS transistor, is constituted of this MOS transistor with a low threshold. A MOS transistor for discharging or charging is constituted of the MOS transistor with the high threshold. Namely, a high-speed dynamic operation can be executed, even if low power voltage VDD is used since pull-down networks 21 and 23 and an inverter 22 are constituted of the MOS transistors of the low thresholds. Furthermore, transistors MN23 and MN26 for discharging the have the high thresholds, and therefore leak current in the transistors MN23 and MN26 becomes considerably low at the time of pre-charging. Thus, power consumption at the time of pre-charging, which occupies the most part of the circuit operation, is reduced.
