Abstract: An indicator is useful for detecting pressure points on a denture. The indicator is made of a composition that easily adheres to oral mucosa, has a proper viscosity in an oral cavity environment, can be properly spread between an oral mucosa surface and a denture base, and easily specifies an affected part. The composition includes a fatty acid ester having a melting point of 30 to 50° C., a water-soluble high polymer, and a metal oxide. Preferably, the fatty acid is 40 to 95% by weight of the composition, the water-soluble high polymer is 1 to 59% by weight of the composition, and the metal oxide is 0.1 to 50% by weight of the composition.

Abstract: A benzimidazole derivative of formula (1): (wherein R represents a hydrogen atom or a methoxy group, and n is 0 or 1) or a salt thereof; and a medicament containing the same. The compounds of the present invention, due to minimized difference in therapeutic effect between subjects, which difference would otherwise be derived from different CYP2C19 activity from subject to subject, ensure that all patients can enjoy proper therapeutic effects at the same dose of the drug. Also, the compounds of the invention have low risk of drug interaction caused by induction of CYP1A family member enzymes, as well as low risk of development of cancer, and thus is useful as a remedy for peptic ulcer, reliably providing therapeutic effects with safety.

The resin composition for denture base is in a one-paste state and is constructed by (a) a polymerizable monomer and/or oligomer having a modulus of elasticity at polymerization of 0.25 to 3.00 GPa, (b) an organic filler and/or an organic-inorganic composite filler having a modulus of elasticity of 0.25 to 3.00 GPa, and (c) a polymerization initiator made of a heat polymerization type polymerization initiator and/or a photopolymerization type polymerization initiator, and optionally, (d) an inorganic filler.

Abstract: A communications device includes a first memory for storing parameter information which defines an operation of the communications device, and a second memory for storing parameter information which defines the operation of the communications device. The parameter information stored in the first memory coincides with that stored in the second memory when a communication can take place. A control unit determines whether or not the parameter information stored in the first memory coincides with that stored in the second memory and allows a transmission operation of the communications device based on the parameter information when it is determined that the parameter information stored in the first memory coincides with that stored in the second memory.

Abstract: A remote control method and system controlling a radio unit so as to readily specify a portion where a failure occurs, and to quickly take recovery measures against the failure includes a supervisory unit located in the vicinity of the radio unit. If abnormality occurs in the operation of the supervisory unit, an alarm signal detecting unit monitors an operation of the supervisory unit, and transmits the alarm signal to an abnormal processing signal outputting unit through a communication control line. When the abnormal processing signal outputting unit receives the alarm signal from the alarm detecting unit, it transmits the abnormal processing signal to an abnormal processing unit through the communication control line. When the abnormal processing unit receives the abnormal processing signal from the abnormal processing signal outputting unit, it executes abnormal processing in accordance with the received abnormal processing signal.
