  • Patent number: 7842361
    Abstract: The invention aims at providing an oxygen-absorbing resin which has excellent oxygen absorption performance and which can dispense with the addition of a transition metal catalyst or the irradiation with a radiation. The invention provides an oxygen-absorbing resin which is obtained by polymerizing a raw material containing a monomer (A) having an unsaturated alicyclic structure bearing a carbon-carbon double bond wherein one carbon atom adjacent to the carbon-carbon double bond is bonded to an electron-donating substituent and a hydrogen atom and another carbon atom adjacent to the carbon atom is bonded to a heteroatom-containing functional group or a bonding group derived from the functional group with the electron-donating substituent and the functional or bonding group taking cis-configuration and which contains the unsaturated alicyclic structure in an amount of 0.

  • Patent number: 7786726
    Abstract: A magnetic sensor that is inexpensive and suppresses changes in offset voltage caused by wear. The magnetic sensor includes magnetoresistance elements having electrical resistances that change in accordance with magnetism changes. The magnetic sensor detects magnetism based on changes in the electrical resistances. The magnetoresistance elements are covered by a protective film. Part of the protective film is etched and eliminated to form a recess.

  • Publication number: 20100075406
    Abstract: By maintaining the cell density during culture at an appropriate level and eliminating the procedure of transferring cells from a container to another container when a large amount of cells are cultured, damage on cells can be reduced, risk of contamination can be lowered, labor saving can be attained and automation can be attained. A cell culture apparatus including: a culture container 11 formed of a soft packing material and having an enclosure part 11-1 in which a culture medium and/or cells being cultured are enclosed is placed; a container table 12 on which the culture container 11 is placed; a roller 13 which is placed on the upper surface of the culture container 11 and divides the enclosure part 11-1 into two or more chambers; and a driving means 15 which relatively moves the roller 13 or the culture container 11, thereby to change the volume of the culture part 11-11 in the enclosure part 11-1 in which a culture medium or cells being cultured are enclosed.

  • Patent number: 4600154
    Abstract: A static expansive demolition agent in the three-dimensional form obtained by compression-molding a powdery composition comprising calcium oxide as the expansive component, an aluminous cement and an alkali or alkaline earth metal salt of boric acid. Said static expansive demolition agent can be placed as it is in holes in a brittle material to be demolished and when water is subsequently poured into the hole the maximum pressure of expansion can be reached in a very short period of time to demolish the brittle material.
