摘要： The present disclosure discloses a feeding apparatus, which includes a motor, a driving unit, and a noise reduction module. The noise reduction module includes an audio receiving unit and a control unit. The audio receiving unit receives the sound generated by the feeding apparatus when the motor is running. The control unit is electronically connected to the driving unit and the audio receiving unit. The control unit sequentially supplies a plurality of motor drive data to the driving unit to drive the motor to run. The control unit sequentially receives a plurality of sound signals corresponding to those motor drive data from the audio receiving unit. The control unit analyzes the sound signals and selects one of the sound signals as an optimized sound signal. The control unit stores the motor drive data corresponding to the optimized sound signal as a setting motor drive data.

摘要： A linear oscillating actuator system which is capable of canceling out the stator vibrations for driving a load with a minimum of vibrations. The system includes an oscillator carrying a permanent magnet as well as an output shaft for connection to the load. A stator assembly is incorporated within a housing and is configured to movably support the oscillator and to carry an electromagnet. The electromagnet generates a magnetic field which interacts with the permanent magnet to reciprocate the oscillator relative to the stator assembly in a linear path. A balancer is added to the system for canceling out undesired stator vibrations. The balancer are commonly supported to the stator assembly to be driven thereby in parallel with the oscillator. The balancer is configured to have a mass generally equal to that of the oscillator and to be devoid of any output member. Thus, the oscillator and the balancer are driven in a counter reciprocating manner, thereby keeping the stator assembly free from counter-vibrations and therefore driving the output shaft with a maximum output power.

The compressor mechanism includes a linear motor which makes a piston reciprocate within a cylinder and a piston oscillation controller. The piston oscillation controller controls oscillations of the piston so as to bring an actual top dead center position of the piston into agreement with a reference top dead center position and alters the reference top dead center position based on a given parameter such as an ambient temperature or a required thermal load of, for example, a refrigerator. An improved structure of the linear motor is also provided.

摘要： A base plate is formed by press processing by cutting out a bottom portion and a side wall portion connected integrally with the bottom portion, and a rotating-shaft insertion hole is formed thereon. The side wall portion is bent at a border portion where the side wall portion is connected to the bottom portion and is curved around the bottom portion, and further both end portions of the side wall portion in the transverse direction are connected to each other. As a result, a cylinder-shaped yoke is formed.

摘要： The present invention relates to an electromagnetic piston engine capable of producing driving power by a reciprocal movement of a piston in a cylinder by electromagnetic force. The present invention has the objects to provide the electromagnetic piston engine which can do without a variety of resistance inherent in internal combustion piston engines, which reduces the weight corresponding to a rotary assembly portion to a smaller value even if a great output is produced, which can be readily employed together with power transmission mechanisms and so on for use with conventional internal combustion piston engines, and which has a high efficiency in energy consumption. The electromagnetic piston engine is provided with the cylinder and the piston made each of a magnetic material as well as with as the cylinder electromagnet having the inner wall of the cylinder magnetizable to a one magnetic pole and with the piston magnetization unit for magnetizing a portion of the piston engageable with the cylinder to a single magnetic pole in a fixed manner. The magnetization of the cylinder electromagnet generates magnetically attracting force between the cylinder and the piston to cause the piston to move in a one direction and thereafter magnetically repellent force to transfer the piston in the opposite direction. This series of the actions are repeated to provide a continual reciprocal movement of the piston.
