    Abstract: The brushless motor has a first and second drive member. The first drive member is equipped with M phase coil groups each having N electromagnetic coils where M is an integer of 1 or greater and N is an integer of 1 or greater. The second drive member has a plurality of permanent magnets, and is able to move relative to the first drive member. The first drive member has 2 (M×N) magnetic body cores. Each phase electromagnetic coil is coiled on a periodically selected magnetic body core at a ratio of 1 to 2M from among the arrangement of 2 (M×N) magnetic body cores.

    Abstract: The brushless electric machine includes a first drive member (30U) having a plurality of permanent magnets (32U); a second drive member (10) having a plurality of electromagnetic coils and capable of movement relative to the first drive member (30U); and a third drive member (30L) disposed at the opposite side from the first drive member (30U) with the second drive member (10) therebetween, and having a fixed relative positional relationship with respect to the first drive member (30U). The second drive member (10) has magnetic sensors (40A, 40B) for detecting relative position of the first and second drive members; and a control circuit for carrying out control of the brushless electric machine utilizing the output signals of the magnetic sensors. The third drive member (30L) has at locations facing the permanent magnets of the first drive member (30U) a plurality of magnetic field strengthening members (32L) for strengthening the magnetic field at the location of the second drive member (10) in conjunction with the permanent magnets.

    Abstract: In an upper tool for a press brake clamped between a support plate (7) of an upper tool holder body (5) attached to a lower portion of an upper table (3) and an upper tool clamp member (11), the upper tool (9) is formed with an inclined surface (9S) narrowed upward at an upper portion thereof and with an engage groove (9G) engaged with an engage projection (11K) of the upper tool clamp member (11) and formed under the inclined surface (9S). Therefore, the inclined surface (9S) is brought into contact with an inclined surface of the upper tool clamp member (11), when the upper tool is clamped between the upper tool holder body (5) and the upper tool clamp member (11), in such a way that clamping force can be-further increased when the upper tool is engaged with a die (63). Further, in an upper tool holder apparatus for a press brake, the pivotal upper tool clamp member (211) is formed with an engage projection (211P) engaged with a drop prevention groove (205G) formed in the upper tool (205), and the upper tool holder apparatus further comprises clamp operation lever (215) for selectively moved to a clamp position A at which the clamping force can be applied to the upper tool clamp member (211) from the clamping force generating spring (213) to clamp the upper tool tightly; an unclamp position B at which the clamping force can be reduced to allow the upper tool to be adjustably shifted horizontally, and an exchange position C at which the upper tool clamp member (211) can be moved way from the upper tool to allow the upper tool to be exchanged vertically with another one.
