  • Patent number: 6687521
    Abstract: The present device is equipped with a measurement site holder 3 that is constructed using a negative impression of the measurement site 10. As a result, variation in the measured values caused by the non-uniform distribution of components in the measurement site 10 is reduced, so that variation in the measured values caused by variations in the light path length accompanying variations in the shape of the measurement site 10, and by variations in blood flow or the like that accompany differences in the contact pressure, can be reduced. Since living-body information and measurement parameters for the patient are recorded on a recording medium 11 mounted on a measurement site holder 3 for the exclusive use of the individual patient, the erroneous acquisition of living-body information for individual patients can be prevented, and reproducible measurements can be performed.

  • Patent number: 5714030
    Abstract: A plastisol type adhesive composition used to bond a filer paper and end caps of an filter element of a fuel filter for filtering a mixture fuel of gasoline and methanol. The adhesive composition comprises a polymer (vinyl chloride polymer and/or copolymer) in an amount of 100 parts by weight, a filler in an amount ranging from 50 to 250 parts by weight, a plasticizer in an amount ranging from 50 to 250 parts by weight, and phenolic resin as an adhesiveness providing agent, in an amount ranging from 0.5 to 20 parts by weight.

  • Patent number: 5075411
    Abstract: A curable epoxy resin composition comprises (I) an epoxy resin and (II) a curing agent. It may comprise (III) another curing agent. It is preferable for it to comprise 25 to 95 wt.% of (I) and 5 to 45 wt.% of (II).1 an epoxy resin (I) represented by the general formula: ##STR1## wherein Z represents a group selected from among a hydrogen atom, a methyl group and an ethyl group, R represents a group selected from among a hydrogen atom and alkyl groups, and n represents a number of 0 to 1.6, and2 a curing agent comprising a polyamine reaction composition (II) obtained by reacting 1 mol of a phenol (II-1) having at least one unsubstituted reactive site in the aromatic nucleus with at least 1 mol of an aliphatic polyamine (II-2) and at least 1 mol of a carbonyl compound (II-3) having at least one carbonyl group in the molecule.
