Abstract: An absolute encoder preferable in being made compact is provided. The absolute encoder includes a first drive gear, a first permanent magnet, a first angle sensor, and a first driven gear of a central axis that is perpendicular to a central axis of the first drive gear, the first driven gear engaging with the first drive gear. The absolute encoder includes a second drive gear coaxially provided with the first driven gear, the second drive gear being configured to rotate in accordance with rotation of the first driven gear. The absolute encoder includes a second driven gear of which a central axis is perpendicular to the central axis of the first driven gear, the second driven gear engaging with the second drive gear. The absolute encoder includes a second permanent magnet provided on a top end side of the second driven gear.

Abstract: An improved plasticized polyvinyl chloride interlayer for laminated safety glass, and an improved method of manufacturing a laminated safety glass including such plasticized polyvinyl chloride containing film is disclosed. An improved functional silane adhesion promoter is utilized in such a manner so as to impact energy dissipation is maximized while structural integrity is maintained. The plasticized polyvinyl chloride interlayer is formulated so as to provide improved long term heat stability at service use temperatures.

Abstract: A method of welding a thermoshrinkable sheet comprises inserting between opposing faces of the sheet to be welded a piece of uncrosslinked resin tape containing peroxide, securing heat-resisting tapes on and adjacent outer faces of a welding portion of the sheet, and heating and pressing the welding portion.A device for use in the method includes a pressing plate having a heater, a receiving plate, a first link pivotally connected at one end to one end of the receiving plate and at the other end to the pressing plate, an operation lever pivoted on one end of the receiving plate, a second link pivotally connected to the free end of the operation lever and to the first link. The first and second links and the operation lever constitute a power amplifier mechanism in which the turning force of the operation lever is amplified to the pressure of the pressing plate through the second and first links.
