20100013492 | STORAGE BATTERY INSPECTING SYSTEM - A storage battery inspecting system includes a power supply unit and an inspecting unit. The inspecting unit includes two inspecting terminals to be connected to a battery soldering spot so as to detect response of the soldering spot to application of a test power signal by the power supply unit, and a control module for determining if a detected response of the soldering spot falls within a predetermined range configured in the control module, generating an indication signal if the detected response falls outside the predetermined range, and generating an inspection result corresponding to the detected response. The inspecting unit further includes an indication interface for outputting the indication signal, a transmission interface permitting supply of the inspection result to a processing device, and a control interface permitting supply of a control signal generated by the control module to a peripheral device for controlling operation of the peripheral device based on the detected response. | 01-21-2010 |
20100066291 | METHOD AND MODULE FOR CONTROLLING ROTATION OF A MOTORIZED SPINDLE - In a method and module for controlling rotation of a motorized spindle driven by a driving unit, a sensing unit is adapted for sensing vibration of the spindle and generates a voltage signal corresponding to the vibration of the spindle. A processing unit is coupled to the sensing unit for receiving the voltage signal therefrom, and outputs a control signal corresponding to the voltage signal upon detecting that the voltage signal is greater than a reference voltage corresponding to a predetermined vibration level of the spindle, such that the driving unit adjusts a rotation speed of the spindle in response to the control signal from the processing unit. | 03-18-2010 |
20100119319 | PROCESSING MACHINE - A processing machine includes a machine bed, a spindle seat, a sliding rail unit, and a driving unit. The sliding rail unit is disposed between the machine bed and the spindle seat. The driving unit is used for driving the spindle seat to move within a slot in the machine bed, and includes a threaded rod journalled on a junction between a bottom wall surface and a lateral wall surface of the machine bed, and a nut member disposed fixedly on a junction between a bottom surface and a lateral side surface of the spindle seat and engaging the threaded rod. | 05-13-2010 |
20100249982 | DISPLACEMENT COMPENSATION CONTROL METHOD AND MODULE FOR AN OBJECT MOUNTED MOVABLY ON A DRIVING ROD UNIT - In a displacement compensation control method and module for an object mounted movably on a driving rod unit and movable between first and second positions relative to the driving rod unit during processing, a detecting unit determines a displacement amount of a free end of the driving rod unit from a reference position in an axial direction of the driving rod unit as a result of thermal deformation of the driving rod unit during high-speed rotation. A control unit controls the driving rod unit to rotate based on the displacement amount so that the object moves between first and second compensation positions relative to the driving rod unit. A distance between the first position and the first compensation position, and a distance between the second position and the second compensation position are equal to the displacement amount. | 09-30-2010 |
20110248447 | Shooting game machine - A shooting game machine includes a shell, a gun, and at least one goal-and-carrier assembly. The goal-and-carrier assembly includes a base located in and attached to the shell, a carrier movably supported on the base, and at least one goal unit. The goal unit includes a frame supported on the carrier, a goal pivotally connected to the frame between a raised position and a shut-down position, a crank rotationally connected to the frame, a lever connecting the goal to the crank, a turntable rotationally connected to the frame, magnets attached to the turntable. The magnets attract the crank so that the goal is retained in the raised position until it is effectively hit by a bullet. A motor is operatively connected to the turntable. The motor rotates the turntable when the goal reaches the shut-down position and stops when the goal reaches the raised position. | 10-13-2011 |
20120294688 | SPINDLE CONTROL SYSTEM FOR A MILLING MACHINE - A spindle control system for a milling machine is provided. The milling machine includes a column, an overarm, a spindle for mounting a cutter, a first motor mounted on the column for driving movement of the overarm, and a second motor mounted on the overarm for driving rotation of the spindle. The spindle control system includes a distance sensor and a temperature sensor, each to be mounted on the overarm and to be disposed proximate to the end portion of the spindle. The spindle control system further includes a central control unit for determining a compensation parameter based on the displacement sensed by the distance sensor and the temperature sensed by the temperature sensor, and for controlling movement of the overarm by the first motor through a compensation distance based on the compensation parameter to compensate for at least one of the cutter deformation and the spindle deformation. | 11-22-2012 |
20120306420 | CONTROL SYSTEM OF MILLING MACHINE - A control system of a milling machine is disclosed. The milling machine has an overarm, a spindle connected to a cutter, a spindle motor, and an X-axis motor, a Y-axis motor and a Z-axis motor. The control system includes a vibration sensor for detecting a vibration level of the spindle. The control system also includes a central control unit configured to adjust a rotation speed of at least one of the X-axis motor, the Y-axis motor, and the Z-axis motor to bring a load current of at least one of the motors to be within a corresponding current range, and configured to adjust a rotation speed of the spindle motor to bring the vibration level to be within a vibration range. | 12-06-2012 |
20130049300 | GAME MACHINE - A prize-displaying apparatus includes a wall, two mounts, two boards, two axles and a motor. The wall includes two apertures defined therein. Each mount includes a horizontal section between two vertical sections. Each vertical section of each mount includes an aperture defined therein. Each board includes a sleeve formed thereon. Each axle is inserted in a related aperture of the wall, the apertures of a related mount and the sleeve of a related board. The motor is operatively connected to one of the axles so that the related board can be pivoted between a supporting position where it supports the other board and a releasing position where it leaves and allows the other board to fall. | 02-28-2013 |
