Inventor: ENOKI KOJI
IPC: F16L59/147
Filed: 1990-03-02
Abstract: PURPOSE:To prevent damage of a jacket due to overheating during operation by calculating the minimum heat insulating thickness of the first layer heat insulating material such that the second layer heat insulating material attains an allowable heat resisting temperature and determining a fixed point in such a manner that the travel of a service pipe due to thermal expansion will not compress the first layer heat insulating material less than the minimum thickness. CONSTITUTION:The minimum heat insulating thickness T of the first layer heat insulating material 13 such that the second layer heat insulating material 14 attains an allowable heat resisting temperature is calculated, and the distance between a fixed point and an unfixed point of bending portion is determined by the calculating expression in such a manner that the travel delta of a service pipe 11 due to thermal expansion will not compress the first layer heat insulating material 13 less than the minimum thickness T.

Title: Integrated circuit device
Inventor: SATOU YASUSHI
IPC: H03K19/0944
Filed: 1982-03-27
Abstract: PURPOSE:To decrease the power consumption, by connecting plural MOS transistors between a potential and an output of one side along with MOS transistors connected opposite to other MOS transistors between a potential and an output of the  other side and then applying signals of phases opposite to each other to the gates. CONSTITUTION:MOS transistors TR11 and TR12 are connected in series, and input signals A1 and B1 are applied to the gates of these MOSTRs, respectively. Then the  source side of the series circuit is earthed to form a circuit 1. MOSTRT13 and TRT14  are connected in parallel to the drain side of the circuit 1, and the drain side and the  source side are connected to a power supply VDD and the drain side of the circuit 1  respectively to form a circuit 2. Then signals A1 and B1 and signals -A1 and -B1 of  opposite phases to the signals A1 and B1 are applied to the gates of the TRT13 and  TRT14, respectively. The joint of the circuits 1 and 2 is defined as an output terminal OUT1 of an NAND gate. When both signals A1 and B1 are set at 0 or one of these  two signals is 0, the OUT1 is cut off from an earth potential and delivers logic 1. Both  A1 and B1 are set at 1, the VDD is separated from the OUT1. Thus the OUT1 is set at  logic 0. As a result, no DC current flows to the earth from the VDD. This decreases the  power consumption.
