Abstract: A conveyor is provided with a supply roll, a plurality of movement parts and a first securing device. The supply roll is rotatably arranged and is configured to support a belt-shaped cell material for an electrode or a separator to intermittently feeding out the cell material by rotation of the supply roll. The movement parts are configured to lengthen and shorten a conveying route by conveyably holding the cell material fed out from the supply roll. The first securing device is configured to secure the cell material. The first securing device is provided upstream from the movement parts along a direction in which the cell material is conveyed. The movement parts are further configured to change position so as to shorten the conveying route in a state in which the cell material is secured by the first securing device.

Abstract: A honing method and honing control device suitable for the honing having a large processing area is provided. The honing control device includes a grinder and an expansion member for disposition in a processing hole of a workpiece. The amount of an expanding movement when the grinder contacts the inner surface of a gauge hole via the expansion member is stored as a target expansion amount by inserting a honing head into the gauge hole having the same size as a target processing diameter of a master gauge. Then, a honing of an inner surface of the processing hole is performed by inserting the honing head within a processing hole of a workpiece moving the grinder towards an outer side of a diametrical direction by the expansion member installed within the honing head to rotate the honing head. The honing is completed when the amount of the expanding movement of the grinder reaches a target expansion amount established by the master gauge.

Abstract: A manufacturing method of an endless metal belt having metal rings built up and differing in circumference, includes the following steps of: a first circumference correction step of expanding each of the metal rings; and a second circumference correction step of expanding each of the metal rings after conducting a solution heat treatment to the expanded metal ring. In the manufacturing method, by executing the first circumference correction step and the second circumference correction step before and after the solution heat treatment, respectively, an expansion quantity for setting a circumference of each of the metal rings to become a predetermined length is attained.

Abstract: A tapped hole measuring apparatus available for automatically measuring the major diameter, minor diameter, effective diameter and depth of a tapped hole. The apparatus comprises a measuring stylus with at least two air discharging ports which can take inserting movement into the tapped hole. The apparatus separately measures the variations of the back pressures of air supplied to the air discharging ports, and converts the back pressure variations into electric signals and stores them. Also included in the apparatus is a configuration calculating section for comparing the variation of the electric signal from the tapped hole with a variation of electric signal from a reference tapped hole to obtain the configurational dimensions of the tapped hole being measured.
