Inventor: KEBUIN ERU SHITSUFUARINGU
IPC: F17C9/02
Filed: 1994-06-24
Abstract: PURPOSE: To supply a cryogen substantially free of higher boiling impurities by providing an internal heat exchanger for vaporizing a portion of liquid cryogen to form a cryogenic vapor, with the remaining portion of the liquid cryogen left in an auxiliary tank to keep higher boiling impurities in a solidified condition. CONSTITUTION: An inlet pipe 32 to be connected to an external heat exchanger 28 and an outlet pipe 34 to discharge cryogenic vapor are fitted to an internal heat exchanger 30. The internal heat exchanger 30 has the surface area sufficient for vaporizing a portion of a liquid nitrogen 14 to be fed into an auxiliary tank 22, and the remaining portion 36 of the liquid nitrogen 14 is left behind. A portion of the liquid nitrogen 14 vaporized in the auxiliary tank 22 forms the cryogenic vapor. Higher boiling impurities are generally re-solidified in the remaining portion 36 of the liquid nitrogen 14, and kept in the liquid nitrogen in a solidified condition. The cryogenic vapor to be discharged from the outlet pipe 34 substantially contains no higher boiling impurities.

Abstract: PURPOSE:To process data at a high speed without using a main storage device of a large capacity by forming a hierachical divided file when processing information consisting of a node and a link. CONSTITUTION:In a main storage device (MM)2, a file is searched for by a node name and pieces of information on types 2 and 3 included in it are read out of disks 3 and 4. For those pieces of information on the types 2 and 3, information on a buffer is transferred to the MM2 by a readout request. When the file is not found, the information is read out of the disks 3 and 4 to buffers 5 and 6, and are transferred to the MM2. When the buffers have no vacancy, LRU algorithm control is performed. Information on reference order is added to the pieces of information on the types 2 and 3 in the MM2. When the space of the MM2 becomes deficient, the information on the types 2 and 3 is expelled to the buffers on the basis of the reference order information to obtain free space in the MM.

Abstract: PURPOSE:To greatly increase the branching frequency of optical signals sent from the same optical bus by using plural types of optical couplers having the optimum branch ratios in accordance with the branching frequency for signal branching. CONSTITUTION:A line 102 consists of an optical fiber whose starting end is connected to an optical transmitter or receiver. The optical couplers 1031-103n corresponding to terminals 1041-104n are put into the line 102 to branch this line 102 to said terminals 1041-104n respectively. Thus an optical bus is formed. Here different branching ratios are given to the couplers 1031-103n and these couplers are arranged at and after the optical transmitter or the optical receiver 101 in the order of larger branching ratios. An approximately equal optical level is secured at each terminal input point by optimizing the branching ratio of each optical coupler. Thus the optical power received from the optical transmitter is effectively distributed to each terminal. As a result, the optical level higher than the desired value is not supplied to a terminal set near the optical transmitter unlike a conventional system. Then the branching frequency can be increased.
