Abstract: PURPOSE:To provide a fuel cell having long cycle-life, which is superior in its efficiency and durability, by using Ba-Ce-O mixed ionic conductive oxide having proton conductivity and oxide ionic conductivity for a solid electrolyte. CONSTITUTION:A material such as perovskite oxide, the composition formula of which is BaCe1-xGdxO3-alpha (1>x>0, 1.5>alpha>0), is used for a solid electrolyte. In this way, the durability and cycle life of a fuel cell is improved because this fuel cell can be operated efficiently at temperature below 850 deg.C and non- ceramic materials such as metals can be used as constitutive materials for such as an air electrode and a fuel electrode of the fuel cell main body, and as peripheral materials and structural materials for such as a bipolar plate, an interconnector and a manifold. It is desirable that the values of x in the composition formula are 0.23-0.16, and the range of the operation temperature is 650-850 deg.C.

Abstract: PURPOSE:To improve detection accuracy by putting a permanent magnet formed of a columnar magnetic rigid body in the columnar space in a casing movably through lubricating oil and detecting displacement from a reference position. CONSTITUTION:The columnar magnetic rigid body 4 is put movably in the columnar case 2 made of a nonmagnetic body.

Title: Sealing medium
Inventor: OOHASHI NOZOMI
IPC: C08J9/04
Filed: 1978-03-22
Abstract: PURPOSE: A sealing medium showing excellent waterproof effect under high compressed conditions that is prepared by foaming and vulcanizing a mixture of a coplymer from ethylene, α-olefin, and polyene, a polyolefin resin, and a foaming agent.  
     CONSTITUTION: Tapes, sheets, or pieces of sealing medium with compression strength of 3 W 25 kg/cm 2 , compression set of less than 50%, and bending resistance of no more than 20 mm are produced by foaming and vulcanizing a composition consisting of 100 parts by wt of a copolymer from ethylene, α-olefin, and a cyclic or acyclic polyene with nonconjugated double bonds, 20 W 300 parts of a polyolefin resin, and an appropriate amount of foaming agent to expand to 1.5 W 1.8 times the original volume. Less than 20 parts of the polyolefin resin reduces the nerve and thus punching and mounting operability, whereas exceeding 300 parts makes the sealing medium too hard and too high in impact resilience, thus becoming lack of sufficient water-tight properties.

A byte pointer/integer arithmetic means 5 adds and subtracts integers from the byte offsets 8 of the byte pointers, and stores the result in the byte offsets 8 and a word address in the word pointers 7 as it is. After a byte pointer comparison means 3 converts the byte pointers into the word pointers 7 by a word pointer conversion means 2, it compares word addresses. Only when the results are the same, the means 3 compares the byte offsets in the word to compare the byte pointers. After a byte pointer difference arithmetic means 6 obtains the difference between the word pointers 7 and muljtiplies it by the number of bytes in the word, it adds the difference between the byte offsets, and calculates the difference between the byte pointers.
