    摘要： A gas sensor which includes a reference electrode deposited on the surface of a pH-sensitive transducer having a gate-insulated field-effect transistor (FET) structure and adjacent a gate region of the FET, the transducer and reference electrode being housed in a flexible tube so that the gate region of the FET is located in an opening provided at the front end of or on the side wall of the tube. Lead wires connected to the FET and to the reference electrode extend along the tube. Between the inner wall of the tube and lead-wire FET bonding part is placed electrical insulation resin filling to stop the tube. A hydrophilic polymer layer containing electrolyte is provided which at least extends over both the FET gate region and a part of the reference electrode. A gas permeable membrane is laid over the polymer layer.

    摘要： A reference electrode of an insulated gate field effect transistor having the surface of the gate region thereof coated with a hydrophobic organic polymer membrane. Since this reference electrode is much smaller in size than conventional reference electrodes, an integrated measurement system can easily be constructed by using this reference electrode. This measurement system is especially effective for measuring various ions in the living body.

    摘要： A cement composition which comprises a filler, a binder to be used in admixture with the filler, and a curing agent for polymerizing the binder, which is characterized by that the binder comprises, based on the total weight of the binder, 20-100% by weight of (A) a free-radical polymerizable monomer of the following formula: ##STR1## wherein R is a hydrogen atom or a methyl group and X is an organic residue having 1-48 carbon atoms, and 0-80% by weight of (B) a mono-, di- or tri-functional free-radical polymerizable monomer which is copolymerizable with the above monomer (A) is disclosed. By using the above binder, the filler is firmly bonded with each other and gives a cured product having high compressive strength and abrasion resistance. The cement composition is especially useful as dental restorative materials.
