Title: Bipolar plate for fused-salt fuel cell
Inventor: NIIKURA JUNJI
IPC: H01M8/02
Filed: 1986-06-04
Abstract: PURPOSE:To impress stack pressure uniformly as well as to maintain cell capacity so stably to the best, by constituting a partial band-form projection of the peripheral part of a gas separator from a metallic porous body. CONSTITUTION:A stainless steel plate, as a bank-form projection 4 at the air electrode side, is diffused-bonded to a gas separator 2 provided with a conductive projection 3 and then a sintered nickel porous plate, as a bank-form projection 1 at the fuel electrode side, is brazed to the separator 2, thus a bipolar plate is produced. Thus, a partial bank-form projection is constituted from a metallic porous body whereby, during cell operation, this metallic porous body produces a creep of the same degree as an electrode so that height of the bank-form projection is reduced synchronously with reduction in thickness of the electrode, impressing stack pressure uniformly at all times. With this constitution, an increase in internal resistance of the cell is brought to nothing, thus stable capacity is maintainable to the best over a long period of time.

Title: Superconductive multiple-terminal element
Inventor: NARA SHIGETOSHI
IPC: H01L39/22
Filed: 1984-06-23
Abstract: PURPOSE:To obtain a superconducting multiple-terminal element, which performs operation with gain and detects space distribution yielded in the relaxation process of quasi-particles that are injected through a Josephson coupling formed on one main surface of a main superconductor layer. CONSTITUTION:A voltage state is formed between a first terminal 9 and a second terminal 10. Quasi-particles are uniformly injected into a main superconductor layer 6 through a second insulating film 7. The temperature of the main superconductor layer 6 is made to be a low temperature so that parameters in superconductivity (order variable, number density of Cooper pairs and variable expressing its phase) develop sufficiently. Then the injected quari-particles are relaxed into the state of the Cooper pairs, which is the ground state, in the main superconductor layer 6. When the amount of injection exceeds a critical value, the uniformly injected quasi-particles undergo uneven relaxation in space. As a result, a pattern, which is steady in time and has irregularity in number density of the quasi-particles having some space period, is yielded in the main superconductor layer 6.

Title: Method and equipment for measuring range of slack or crack in ground, bed rock, concrete structure, and the like
Inventor: CHIKAHISA HIROSHI
IPC: E02D33/00
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To ensure an accurate measurement by inserting ultrasonic measuring units in holes made in the outer circumferential surface in a cavity at a plurality of measuring points and measuring the range of slack or crack in the ground from the difference of measured ultrasonic velocity thereby eliminating restriction in the measuring direction. SOLUTION: Ultrasonic measuring units 3 are inserted sequentially into a plurality of anchor holes or boring holes 2 made in a cavity, e.g. a tunnel or a basement. A stopper 9 is stretched on the outer surface of the anchor hole or boring hole 2 so that the anchor hole or boring hole 2 can be stopped at a measuring point even if it elongates vertically upward. An ultrasonic transmitter 4 is then actuated to transmit an ultrasonic wave which is received by an ultrasonic receiver 5. An ultrasonic velocity detector 12 detects the velocity of an ultrasonic wave from a received ultrasonic wave group and an indicator 13 indicates the velocity for each depth of the hole thus recognizing a slack or crack in the ground.  When a decision is made that the slack in the ground is localized, an accurate measurement can be performed by limiting the fixing interval of the ultrasonic transmitter 4 and the ultrasonic receiver 5.
