    Abstract: The single-phase brushless motor according to one aspect of the present invention includes a coil array having a plurality of magnetic coils 11-14; a magnet array having a plurality of permanent magnets 31-34; a magnetic sensor 40 for detecting relative position of the magnet array and the coil array; and a drive control circuit that, utilizing the output signal SSA of the magnetic sensor, generates application voltage for driving the coil array with a single-phase drive signal. The coil array includes a magnetic member 20. This magnetic member 20 is constituted such that, with the single-phase brushless motor at a stop, the centers of the permanent magnets 31-34 come to a stop at locations offsetted from the centers of the magnetic coils 11-14, due to attraction of the magnetic member 20 by the magnet array.

    Abstract: An easy manufacturing method of a slip stopper, and apparatus therefor, that has a great slip stopping effect and can be used for a location where a problem occurs if a though hole is opened therein. After a protruding portion is formed on a steel plate, by using a first punching die unit, so as to protrude from the upper surface in a plate thickness direction, a concave portion and drain channels are formed in the protruding portion by shear planes that extend substantially perpendicular to the steel plate upper surface and have been half-blanked so as not to open a through hole in the steel plate by using a second punching die unit.

    Abstract: In the case where an upper punch and a die are made rotatable, a lower punch that is fixed in a conventional example is rotatably supported. Further, a guide mechanism with fixed helical lead for guiding the die is constructed of a guide whose lead is identical to a lead of helical gear contour, and a cam follower that engages with the guide. The guide and the cam follower are arranged so as to correspond to the die and a part with fixed helical lead that is a newly arranged component in the invention. The meshed portion between the helical gear contours of the upper and lower punches and helical gear contours formed on a die or a core rod is free from any excessive force even when a lead-phase shift occurs between helical gears formed on upper and lower punches due to the flexing of the punches during compression.

    Abstract: An upper tool clamp is provided that is supported by a holder body arranged on an upper table of a press brake, so that the upper tool clamp can be oscillated between a clamped state and an unclamped state. A pressing member is mounted on a lower portion of the upper tool clamp in order to press an upper tool on an upper tool support portion which is mounted on a lower portion of the holder body. Further, an engage projection is formed on the upper tool clamp and freely engageable with a drop prevention groove which is formed on the upper tool. In addition, a first clamp/unclamp device and a second clamp/unclamp device are mounted on the holder body, respectively.

    Abstract: A method and device for measuring clearance between gears of an internal gear having an inner gear and an outer gear. With the inner gear fixed, the outer gear is set around the inner gear and brought into abutment with the inner gear at one side. The outer gear is then moved in the opposite direction to butt the inner gear at the outer side. The clearance between the two gears is determined by measuring the distance for which the outer gear moves. This method is much simpler and time-saving than a conventional method using clearance gauges.
