  • Patent number: 10669439
    Abstract: A resin for an active energy ray curable ink contains a rosin-modified unsaturated polyester resin (A). The rosin-modified unsaturated polyester resin (A) is a reaction product of a material component containing rosins (a), ?,?-unsaturated carboxylic acids (b), and polyols (c); the mole ratio of an unsaturated bond based on the ?,?-unsaturated carboxylic acids (b) with respect to the total amount of the material component is 0.50 mol/kg or more and 2.00 mol/kg or less; the rosins (a) contain a stabilization-treated rosin at a ratio of 90 mass % or more with respect to the total amount of the rosins (a); the ?,?-unsaturated carboxylic acids (b) contain ?,?-unsaturated dicarboxylic acids; and the polyols (c) contain a trihydric or more alcohol.

  • Patent number: 9071088
    Abstract: There is provided an axial gap type generator exhibiting improved precision in positioning stator cores. An axial gap type generator comprises a generator case fixed to a crank case of an engine, a rotor yoke housed inside the generator case, and fixed to a crankshaft of the engine, and a first stator core and a second stator core fixed to generator case inner faces, and disposed flanking the rotor yoke in a rotation axis direction. The generator case is configured through direct connection of a first member to which the first stator core is fixed and a second member to which the second stator core is fixed.

  • Patent number: 8941279
    Abstract: There is provided an axial gap type generator. The axial gap type generator includes: a stator core fixed to a crank case of an engine; a rotor yoke fixed to a crankshaft of the engine and opposing the stator core across spacing in an axial direction of the crankshaft; a first planar section provided in the crankshaft and formed to have a planar shape that is perpendicular to a rotation center axis; a second planar section provided at a base, at which the rotor yoke is mounted on the crankshaft, and disposed opposing the first planar section; and a shim clamped between the first planar section and the second planar section.

  • Patent number: 6417643
    Abstract: A synchronous control device according to the present invention completes an origin matching between a master section and a slave section without causing a phase difference even when a deceleration device is employed in the master section or in the slave section so as to perform an accurate synchronous control. The synchronous control device constantly detects the phase of a shaft of a master electric motor by a phase detector of the master electric motor according to the outputs of a master rotary encoder, and the phase of a shaft of the master machine by a phase detector of the shaft of the master machine according to the outputs of a master rotary encoder and an origin detector of the shaft of the master machine.
