Abstract: A composition containing polytetrafluoroethylene and substantially free from a compound represented by Formula (3): (H—(CF2)8—SO3)qM2 wherein M2 is H, a metal atom, NR54 (where R5s may be the same as or different from each other and are each H or an organic group having 1 to 10 carbon atoms), an imidazolium optionally having a substituent, a pyridinium optionally having a substituent, or a phosphonium optionally having a substituent, and q is 1 or 2. Also disclosed is a molded boy including the composition.

Abstract: A camera is provided having a finder optical system, a photographing optical system separate from the finder optical system, and a macro photographing mode. The camera includes a movable field frame which is normally located at an inoperative position in which it is retracted from an optical axis of the finder optical system, and which is moved to an operative position in which the movable field frame is in the finder optical axis in association with the transfer into the macro photographing mode. The movable field frame is provided with a field opening corresponding to a photographing range of the photographing optical system.

Abstract: A paper currency sorting and counting apparatus comprises a first separating unit adapted for separating damaged notes and sound notes supplied through a judgement unit designed to judge the authenticity as well as damaged the state of supplied banknotes of various nominal values, a stacker for stacking reject notes, a second separating unit for sensing the front and reverse sides of the normal notes and controlling the route of these normal banknotes, and a stacker for normal notes having a pair of vane wheels for stacking the normal banknotes in order to provide for automatic sorting of the supplied banknotes.

Abstract: An apparatus for binding paper sheets stacked within a hopper into bundles each consisting of a predetermined number of paper sheets is disclosed. The apparatus comprises a separating drum receiving the paper sheets from the hopper and feeding them out by one, a counter counting the number of paper sheets fed from the separating drum, and a stacker capable of moving between a sheet receiving and a sheet discharging position. When the stacker in the sheet receiving position receives the predetermined number of paper sheets, it is moved to the sheet discharging position and the paper sheets therein are discharged onto support blocks of a binding unit by a transfer device. The binding unit binds the predetermined number of the paper sheets into a bundle with a tape, and a stamping device stamps predetermined particulars on the tape wound around the paper sheets.

Abstract: A humidity sensor element comprising a metal oxide semiconductor sintered member having a composition composed of TiO.sub.2 and V.sub.2 O.sub.5, the member being formed with a pair of electrodes. When the element is used at a temperature of less than 400.degree. C., it is possible to detect the humidity as a variation of electric resistance.
