Abstract: A display screen generation apparatus includes: an acquisition portion acquiring for each of a plurality of print products produced through a plurality of processes, progress of the processes; and a display portion generating a display screen that displays for each of the plurality of print products, the process waiting to be executed, the process being executed, the process already executed, and the process not intended to be executed in a distinguishable manner from each other.

Abstract: The height of protuberances present on the surface of a product, typically a bump wafer, can be measured with a high accuracy irrespective of the state of the upper surfaces of the protuberances. In the signal processor of a bump height measuring apparatus, a bump height measurement area setting section set a bump height measurement area by the bump layout information, a statistical application section averages the height data in an statistical calculation within the measurement area, a contour line calculating section calculates a contour line of a section of the bump, and a bump height determining section determines a peak value in the contour line as the height of the bump.

Abstract: In an oil pump having an inner rotor and an outer rotor supported in a housing, pressure in a pumping chamber whose volume is at maximum presses the inner rotor inwardly and the outer rotor outwardly. An oil groove which communicates with a discharge port via a lubricating groove is formed in an inner surface of the housing at the circumferential position of the pumping chamber whose volume is at maximum. The oil groove has axial sealing surfaces.
