A vacuum plastic molding machine includes a heating device, a plurality of upright posts, a carrier assembly, and a demolding mechanism. The carrier assembly includes an upper carrier and a lower carrier. The upper carrier includes an upper frame, multiple upper movement structures, at least one rotation plate, at least one driving member, and at least one linking mechanism. An adjusting space is defined between the at least one rotation plate and the at least one linking mechanism. The lower carrier includes a lower frame, multiple lower movement structures, and at least one locking tenon. The locking tenon is placed into the adjusting space. The at least one driving member is rotated to change the position of the at least one locking tenon in the adjusting space, and to adjust the distance between the upper carrier and the lower carrier.

Vacuum plastic molding machine

A thermal magnetic engine and a thermal magnetic engine system are disclosed. The thermal magnetic engine includes a fixed element, a rotation element, working fluid and a fin structure. The rotation element includes a working material. The rotation element rotates relative to the fixed element. The working fluid flows through the rotation element and forms a temperature difference on the working material. The fin structure is disposed on the rotation element. The rotation element rotates along a rotating direction due to the temperature difference on the working material and/or due to the flowing of the first working fluid through the fin structure.

Thermal magnetic engine and thermal magnetic engine system

A thermomagnetic generator is provided, including a switch valve, a plurality of magnetic circuit units, a coil, and a plurality of inlet pipes connecting the magnetic circuit units to the switch valve. Each of the magnetic circuit units includes a magneto-caloric member. The switch valve repeatedly and alternatively switches at a predetermined frequency to guide hot and cold fluids to the magnetic circuit units, such that the magneto-caloric members are magnetized and demagnetized, respectively, by the cold and hot fluids. The coil is coupled to at least one of the magnetic circuit units for obtaining an induced voltage.

A front-end module for multi-band and multi-mode wireless network system is disclosed. The front-end module includes a diversity switch, two channel-separating devices, a plurality of band pass filters, a plurality of baluns, and a plurality of low pass filters. The number of the band pass filters, the number of the low pass filters, and the number of the baluns are the same as the number of the channels for carrying a radio frequency signal. In addition, all the band pass filters are connected to one channel-separating device while all the low pass filters are connected to the other one, and the baluns are one-on-one connected to the band pass filters.

Front-end module for multi-band and multi-mode wireless network system

A front end module for wireless network system is disclosed. The front end module includes a transmitting/receiving switch, a bandpass filter, a balun, a lowpass filter, and a power amplifier. The front end module is characterized in that the bandpass filter, the balun and the lowpass filter are formed inside a plurality of low-temperature-cofired-ceramic (LTCC) substrates by a patterning process while the transmitting/receiving switch, and the power amplifier are formed on a surface layer of the LTCC substrates by the surface mounting technology (SMT).

Front end module for wireless network system

A high-frequency filter whose main structure is formed by stacking a plurality of patterned substrates. The high-frequency filter includes a metal grounding layer, a signal input port, a signal output port, and a plurality of resonator layers having resonators coupled to one another for transmitting signals. By utilizing coupling among resonators located on adjacent layers respectively instead of coupling among resonators on a single layer in the prior planar patterned filter, the structure of the high-frequency filter in the invention can be changed according to process limitations.

High frequency filter

A circuit board having a VCO that can be adjusted during manufacturing is disclosed. The VCO has a resonating circuit, a coupling circuit, and an oscillating circuit. The coupling circuit and the oscillating circuit have adjustable capacitors composed of micro-strips on two conductive layers of the circuit board with an insulation layer between the two conductive layers. The micro-strips are cut in different directions by laser beams to adjust the capacity of the capacitors or to make the capacitor react as inductance so that the output frequency and the phase noise of the VCO is accurate or good enough to improve the production's yield rate.
