Abstract: A diaphragm subassembly comprises a voice coil, a diaphragm, a frame, and a pair of terminal members. A magnetic circuit unit comprises a yoke, a magnet, and a base. The diaphragm subassembly and the magnetic circuit unit are accommodated in a bottomed cylindrical cover. In the manufacturing process, the cover is placed with the open end directed upward. The diaphragm subassembly, the yoke, the magnet, and the base are dropped into the cover in this order. The manufacturing process of a dynamic electroacoustic transducer is thereby simplified.

Abstract: A machine tool and a control method therefor providing an improved machining accuracy even when a numerical control and electronic cam control coexist. The CPU determines the moving position of the workpiece, the tool, and the drilling tool according to the command from each channel machining sequence storage portion, and outputs the determined position as a command signal in response to the pulse signal generated at the pulse signal generating circuit. The workpiece, the tool, and the drilling tool are thereby electronic cam controlled. The CPU also determines the moving position of the workpiece and the tool according to the command from each channel machining sequence storage portion, and outputs the determined position as a command signal in response to the divided timing signal generated at the divided timing signal generating circuit. The workpiece and the tool are thereby numerically controlled.

Abstract: A contour shape of a desired shape of a workpiece at section along a predetermined axis is divided into machining units. Each of the machining units includes a plurality of inflection points including a machining start point and a machining end point. Machining data at least necessary for performing machining is set for each of the machining units. Arrival times at the inflection points are calculated based on the machining data, and a position of at least one of the workpiece and the tool is calculated for each of the inflection points. For each of the machining units, a rotation angle position of the workpiece corresponding to the arrival time is set as an accumulated count value.

Abstract: A chuck operating apparatus includes a claw, a shifter, and a shifter drive unit. The rotatable claw has a first posture to bring the chuck into the opened state and a second posture to bring the chuck into the closed state. The rotatable shifter is brought in a first position to bring the claw into the first posture and in a second position to bring the claw into the second posture. The shifter drive unit has a shifter lever having an insertion part provided with a shifter bearing capable of being brought into contact with a side surface of an outward groove of the shifter. A roller is provided on one of the claw and the shifter in a contact position with the other to roll in a spindle axis direction and a groove is formed on the other to receive the roller when the chuck is in the opened state.
