Abstract: There is provided an oral biofilm inhibitor having an exceptional inhibitory effect on oral biofilm formation. It is an oral biofilm inhibitor comprising a curable composition containing an antimicrobial agent, wherein a compressive strength of a cured product formed by curing the composition is 150 MPa or less, and a content of the antimicrobial agent is 0.001 to 3% by weight. An oral biofilm inhibitor thus obtained is used for inhibiting biofilm formation in an oral cavity by applying a curable composition containing an antimicrobial agent to a dental defect site for allowing the composition to cure at the dental defect site, and then disintegrating the cured composition.

Abstract: A kit for bonding to biological hard tissues, containing a phosphorylated polysaccharide, a polyvalent metal salt other than phosphates, and a solvent. The adhesive composition for biological hard tissues provided by the kit for bonding to biological hard tissues is suitably used in for medical uses, such as cement for bones or dental cement.

Abstract: A small-sized centrifugal pump is improved in its efficiency and performance by having an impeller the height of which is higher than theoretically calculated value and decreases in the circumferential direction from the central portion, and which has a flow channel with a narrow and constant width.

Abstract: A windshield wiper motor is provided with an auto-stopping switch having a first contact plate, a second contact plate, a third contact plate and a contact shoe for contacting with said third contact plate at all times and for contacting selectively with said first or second contact plate by sliding reciprocatively on a straight line in accordance with rotation of the final gear of reduction gear. It is possible to prevent the auto-stopping switch from chattering caused by snow gathered in the vicinity of a stopping position of a wiper blade in snowfall.

Abstract: A method for insulating a coil of a rotary electric machine resulting in improved insulating properties at critical coil ends. A mica sheet or mica tape is wound around a part of each coil to be inserted into a slot cut in an iron core of the rotary electric machine to thus form a first insulating layer. The coils thus treated are inserted into respective slots and are connected together and to external terminals as required. Each coil end is then covered in its entirety with a thermosetting resin. The thermosetting resin is hardened by heating to form a second insulating layer.
