摘要： A motor includes three-phase coils formed of coils of different phases and including a first coil end (61) and a second coil end (71) arranged side by side in a circumferential direction of a stator core (21). The first coil end (61) and the second coil end (71) have a first facing portion (62) and a second facing portion (72), respectively. The motor includes an interphase insulator (51) provided only on the first facing portion (62) among the first facing portion (62) and the second facing portion (72). Each of the first coil end (61) and the second coil end (71) is formed of a plurality of coils of the same phase that protrude onto an end face (26) from a plurality of slots (24) arranged side by side continuously in the circumferential direction of the stator core (21). The first facing portion (62) corresponds to all of the plurality of coils forming the first coil end (61), and the second facing portion (72) corresponds to all of the coils forming the second coil end (71).

摘要： A processing machine includes a splash guard (181), a tool spindle (121) that is provided inside a processing area (110) and holds a tool, and an automatic tool changer (141) that is movable between an internal-side tool changing position (Pb) inside the processing area (110) and a standby position (Pa) outside the processing area (110) and changes the tool held by the tool spindle (121) at the internal-side tool changing position (Pb). The splash guard (181) includes a cover body (612) that is coupled to the automatic tool changer (141), defines and forms the processing area (110) when the automatic tool changer (141) is positioned at the standby position (Pa), and enters the processing area (110) when the automatic tool changer (141) moves from the standby position (Pa) to the internal-side tool changing position (Pb).

摘要： A processing machine includes a splash guard that defines and forms a processing area (110), a tool spindle (121) that is movable in a Z-axis direction and a Y-axis direction inside the processing area (110), an additive-manufacturing head (131) connected to the tool spindle (121), and a line body (210) that extends from the additive-manufacturing head (131), is drawn from an inside of the processing area (110) to an outside, and supplies material powder and a laser beam to the additive-manufacturing head (131). A maximum movement amount of the tool spindle (121) in the Y-axis direction is shorter than a maximum movement amount of the tool spindle (121) in the Z-axis direction. A drawing direction of the line body (210) from the inside to the outside of the processing area (110) is a direction intersecting the Z-axis direction in top view.

摘要： A machine tool includes: a movable body that supports a tool; a feed drive unit that feed-drives the movable body; a numerical control unit that controls the feed drive by the feed drive unit to perform cutting by the tool; an acceleration sensor that is provided on the movable body and detects acceleration of the movable body; and a command unit that outputs a stop command to stop driving of the feed drive unit to the numerical control unit when the acceleration of the movable body exceeds a threshold value set in advance on the basis of an output of the acceleration sensor. The command unit sets the threshold value to a first threshold value in a cutting control state, and sets the threshold value to a second threshold value lower than the first threshold value in a feed control in a non-cutting control state.

摘要： A touchscreen device includes a touchscreen (2), support parts (6a, 6b, 6c, 6d) supporting a periphery of the touchscreen (2), and an information output unit outputting information corresponding to an external force acting on the touchscreen (2). Each support part (6a, 6b, 6c, 6d) has thereon a pressure sensor (10a, 10b, 10c, 10d) arranged such that a pressure sensing surface thereof is in contact with the periphery of the touchscreen (2) and has a predetermined angle with respect to a planar surface of the touchscreen (2). The information output unit is configured to recognize, based on detected values detected by the pressure sensors (10a, 10b, 10c, 10d), an acting direction along the planer surface of the touchscreen (2) of the external force acting on the touchscreen (2) and output, to the outside, information on the acting direction and positional information detected by the touchscreen (2) for a position on the touchscreen where the external force is acting.
