Abstract: A machine tool that generates internal teeth or external teeth on a cylindrical workpiece includes a workpiece holder, a column which is relatively movable to the workpiece holder, a rotary main spindle which is rotatable with respect to the column, a working tool which is held by the rotary main spindle, and a phase detecting unit which detects a phase of the working tool with respect to the rotary main spindle. The working tool includes a cutter portion which has cutters, a holder portion, and a detected portion which is formed on the holder portion. The phase detecting unit includes a detecting section which detects the detected portion, and a calculating section which calculates a phase angle of the detected portion with respect to a reference position of the rotary main spindle, based on a result detected by the detecting section.

Abstract: A casting belt 86 is produced of stainless steel. On a casting surface 86a on which a dope 61 is cast, two points P1, P2 arranged in the widthwise direction X of the casting belt 86 are determined, such that the length L between two points P1P2 may be 10 mm. When a depth between the top and the bottom of the surface unevenness might is continuously measured along the line P1P2, a depth maximum DE is at most 40 ?m. Thus even if the film production is made for a long time, it is prevented that austenite partially transforms to martensite. Therefore, the scratches and deformations extending in the lengthwise direction hardly occur.

Abstract: A paper sheet manipulating apparatus and a paper sheet transaction apparatus for manipulating paper sheets such as bills has an inlet/outlet port allowing input and output of paper sheets and rotating between the paper sheets inlet position and the paper sheet feeding position; a separating device projected to the outlet port and drawn back to the draw-back position, distinguished, when projected, the paper sheets inputted to the inlet port and the paper sheets to be returned and accommodate the paper sheets into the outlet port; an accommodation section for accommodating the paper sheets; a temporary storing section for temporarily storing the paper sheets which should not be accommodated in the accommodation section or should not be exhausted and a plurality of cassettes for feeding and collecting the paper sheets in the accommodation section and for feeding and collecting the paper sheets in the outlet port, whereby few faults are generated and manipulations can be continued at a high speed for a long peri
