  • Patent number: 11312831
    Abstract: The present invention relates to a carrier for bio-related molecule immobilization, which comprises a resin substrate, an amino group-containing compound layer that is formed on the resin substrate, and a polyvalent carboxylic acid layer that is formed on the amino group-containing compound layer. The carboxyl groups in the polyvalent carboxylic acid layer are actively esterified; and the (COO peak intensity)/(C—C peak intensity) ratio of the C1s spectrum is from 0.064 to 0.12 (inclusive) if the carrier surface before the active esterification is measured by X-ray photoelectron spectroscopy.

  • Patent number: 9736891
    Abstract: An induction heating container (1) in which an induction heat generator (3) is attached to the inside of a container main body (2) made of a non-conductive material so as to enable cooking by heating by an electromagnetic cooker. The induction heat generator (3) includes: a laminated body involving a conductor layer (4) that generates heat by induction of eddy current by high-frequency magnetic field and a heat-seal layer (5) that imparts heat-sealing properties to the container main body, and an eddy current control part (6) obtained by cutting the conductor layer (4) along the circumferential direction.

  • Patent number: 9150931
    Abstract: A plurality of probes are immobilized on a carrier for detecting food poisoning bacteria, the plurality of probes being selected, either alone or in combination, respectively from two or more groups among a first probe group for detecting Escherichia coli, a second probe group for detecting Listeria, a third probe group for detecting Campylobacter, a fourth probe group for detecting Vibrio parahaemolyticus, a fifth probe group for detecting Staphylococcus aureus, a sixth probe group for detecting Salmonella, and a seventh probe group for detecting Bacillus cereus. Two or more types of food poisoning bacteria among Escherichia coli, Listeria, Campylobacter, Vibrio parahaemolyticus, Staphylococcus aureus, Salmonella, and Bacillus cereus can be specifically and simultaneously detected using the carrier.

  • Publication number: 20150215995
    Abstract: To provide an induction heating container that can be used safely in which bumping that occurs when a liquid object to be heated such as water or soup accommodated therein is heated by an electromagnetic cooker is effectively suppressed, thereby preventing a user from getting burned or the surrounding area of the electromagnetic cooker from being contaminated. This induction heating container 1 is an induction heating container in which an induction heat generator 3 is attached to the inside of a container main body 2 that is made of a non-conductive material so as to enable cooking by heating by an electromagnetic cooker, wherein the induction heat generator 3 comprises: a laminated body involving a conductor layer 4 that generates heat by induction of eddy current by high-frequency magnetic field and a heat-seal layer 5 that exhibits heat-sealing properties to the container main body, and an eddy current control part 6 that is obtained by cutting the conductor layer 4 along the circumferential direction.
