Abstract: A cBN sintered compact in accordance with an embodiment of the present invention comprises: cBN grains in the amount of 40 vol % or more and 80 vol % or less; and a binder phase containing titanium boride grains. The cBN sintered compact satisfies the following relation: 3.0?X/Y?10.0, where Y is the sum of the lengths of envelopes on which the cBN grains are in contact with the binder phase, and X is the sum of the interfacial lengths of the titanium boride grains that are present within 2 ?m from the surfaces of each cBN grain and have an oblateness of 1.3 or more and 30.0 or less where the oblateness is defined by L2/(4?S), where L is the interfacial length and S is the area of the titanium boride grain.

Abstract: A gas adsorbing device (5a) according to the present invention includes a gas adsorbing material (9) that adsorbs at least nitrogen and a housing container (11) that has a long, thin, flat, tubular shape and is made of metal and in which both sides of a housing portion (10) configured to house the gas adsorbing material (9) under reduced pressure are sealed. A contact portion (13) where opposing inner surfaces of the housing container (11) are in close contact with each other is located between at least one of seal portions (12a and 12b) of the housing container (11) and the housing portion (10).

Abstract: A sealed container (1) includes: a metal container (3) including an opening portion (5) and a first internal space that is reduced in pressure; a solid matter (4) contained in the first internal space of the metal container; and a sealing member (2) made of glass containing at least alkali earth metal oxide or alkali metal oxide, and the sealing member is melted by heating and solidified by cooling to be joined to and seal the opening portion of the metal container.

Abstract: A heat-insulating box (1) according to the present invention includes: an outer casing (2); an inner casing (3) accommodated in the outer casing, such that heat insulating space is formed between the inner casing and an inner surface of the outer casing; a plurality of vacuum insulation panels (10) arranged in the heat insulating space; and a foam insulating material (4) which fills space in the heat insulating space other than the plurality of vacuum insulation panels. Each of the plurality of vacuum insulation panels includes at least a core material and a moisture adsorbent, and the core material and the moisture adsorbent are decompression-sealed in space covered by an outer skin material.
