  • Publication number: 20060168983
    Abstract: A compact ice-making device is provided for making ice chips of varied shapes for use in glasses of whiskey and water, and the like purposes. Ice is made using an ice-making vessel (13) for making a plank-like block of ice with a shaft (18) inserted in advance in the vessel, the shaft (18) having ribs (18A) extending substantially radially from a rotating axis. Upon completion of the ice making, a gear unit (20) connected to the shaft (18) is driven by a motor to rotate the shaft (18), which cracks and divides the plank-like ice block into ice chips of varied shapes.

  • Patent number: 6809454
    Abstract: In a motor having a motor unit and a speed-reducing unit, a brush holder is sandwiched between a yoke housing of the motor unit and a gear housing of the speed-reducing unit. The brush holder includes holder body, joining portion, and connector portion. The holder body is formed with a first opening being open in the yoke housing. The joining portion is formed with a cylindrical portion extending in a direction same as the opening direction of a connector recessed portion of the connector portion. A second opening is formed on an end surface of the cylindrical portion. The first opening communicates with the second opening through first and second communication holes, so that pressure difference between the inside and outside of the yoke housing and the gear housing are cancelled.

  • Patent number: 6798102
    Abstract: A clutch is arranged between a rotatable shaft and a worm shaft in a motor. The clutch includes a driving-side rotator connected to the rotatable shaft, a driven-side rotator connected to the worm shaft, a spring support and a coil spring arranged in the spring support. When the driving-side rotator is rotated upon energization of the motor, the coil spring is wound by the driving-side rotator to reduce an outer diameter of the coil spring, so that the rotation of the driving-side rotator is transmitted to the driven-side rotator and the worm shaft. When the driven-side rotator is rotated by an external mechanical force, the coil spring is unwound by the driven-side rotator to increase the outer diameter of the coil spring, so that a frictional force between the spring support and the coil spring is increased to restrain rotation of the driven-side rotator.

  • Patent number: 6752688
    Abstract: In the cutting solution supplying and controlling apparatus for a dicing machine, a flow rate adjusting device is provided in addition to a regulator as the pressure adjusting device. The flow rate adjusting device has a flow rate controller, which controls a proportional solenoid valve according to a signal applied from a flow rate sensor as a feedback signal. Thus, even if the pressure of the water supplied from the water supply equipment of the factory changes, the flow rates of the cutting solution and the coolant are maintained. Moreover, the flow rates can be easily adjusted according to the type of work to be processed.

  • Patent number: 6743076
    Abstract: The flange cover covering the blade is divided into two. The second cover is turnably connected to the first cover through a shaft parallel with the spindle of the blade, and the second cover is opened and closed in connection with vertical movement of the spindle. When the spindle is moved upward for replacing the blade, the second cover is automatically turned to the opening position, and L-shaped coolant jetting nozzles are moved away from positions below the blade to positions beside the blade. Thus, the blade can be easily replaced, and an automatic blade replacing system can be applied.

  • Patent number: 6732612
    Abstract: With a blade exchanging device, a cylindrical body is engaged with a nut that is fastened to a spindle, and at the same time the nut is held by fitting nails of a chuck member with grooves that are formed on the nut. Next, a torque wrench is inserted through the cylindrical body, and a polygonal head of the torque wrench is engaged with a polygonal hole formed in the head of the spindle. In this state, the spindle is rotated with the torque wrench in a direction to unfasten the nut from the spindle. The nut is thereby detached from the spindle. When the cylindrical body is disengaged from the spindle, the nut is prevented from falling off the cylindrical body, since the nails of the chuck hold the nut.

  • Patent number: 6733377
    Abstract: The dicing machine has a shielding plate movably arranged between a processing part and a microscope so as to check mist and spray produced from the processing part. The shielding plate can be moved back and forth between a shielding position and a retreated position, so that the shielding plate is positioned at the shielding position during processing of the work and at the retreated position when the operator replaces the old blade with a new one. Thus, even if the dicing machine has two spindles facing to each other, the shielding plate does not interfere with replacement of blades on the spindles.
