Abstract: A toilet seat includes: a bottom plate including an engaging part; a top plate including a sidewall part provided on the bottom plate and a seating part supported by the sidewall part; and a bonding member having an exposed surface exposed externally. The engaging part is provided at a position opposing the sidewall part and has a recessed shape recessed downward. The sidewall part includes a sidewall base, a first hanging part extending downward from the sidewall base and engaging the engaging part, and a second hanging part provided to be separated from the first hanging part at the sidewall base to provide a recess recessed upward between the first hanging part and the second hanging part, the second hanging part being disposed at a position not overlapping the bottom plate. A side surface of the engaging part faces away and also extends away from the second hanging part.

Abstract: A toilet seat includes a bottom plate, a top plate, and a bonding member. The top plate includes a sidewall part and a seating part. The sidewall part is provided on the bottom plate along a vertical direction. The seating part is supported by the sidewall part. The bonding member bonds the bottom plate and the sidewall part. The bonding member has an exposed surface exposed externally. The exposed surface is positioned below a central plane of the bottom plate and positioned outward of a central plane of the sidewall part.

Abstract: A toilet seat includes a body, a bottom plate, and a joining member. The body includes a seating part and a side wall part. The side wall part extends from each of an inner end and an outer end of the seating part. The bottom plate includes a bottom plate part and a protrusion part. The bottom plate part and the seating part face each other. The protrusion part protrudes laterally from the bottom plate part and is configured to be pressed by an end of the side wall part. The joining member joins the body and the bottom plate. The joining member is formed of a filling material poured to closely contact a side surface of the bottom plate part and a non-pressing surface other than a surface pressing the protrusion part on the end of the side wall part.

Abstract: In a hydrostatic gas bearing for use in a vacuum, in order to provide a hydrostatic gas bearing in which an increase in the quantity of gas being discharged during the movement of a moving body is reduced, the surface of a guide shaft of a fixed body and/or the surface of the moving body is subjected to processing for reducing adhesion of gas molecules, for example, by coating the surface(s) with a material having a low adhesion probability of gas molecules, by which the quantity of gas being discharged is decreased.

Abstract: A sheet feeding apparatus for intermittently feeding sheets one by one into printing equipment. The apparatus comprises a sheet pickup roller fixed to a rotatable drive shaft, a pair of cylindrical rollers rotatably and coaxially coupled to the drive shaft and disposed at both sides of the sheet pickup roller, and a pad biased by a spring to be pressed against the sheet pickup roller and the cylindrical rollers. The sheet pickup roller has a cross section comprising an arc portion and a chord portion to substantially form a semicylindrical configuration. Also included in the apparatus is a projection provided at the chord portion of the sheet pickup roller. The projection is arranged to come into contact with the sheet over a range from a contact point between the sheet pickup roller and the pad to one end portion of the arc portion which acts as a leading portion at which the sheet pickup roller initially comes into contact with the sheet when rotating in a predetermined direction.
