Abstract: An aquarium with a wireless power supply function is disclosed. In the aquarium, a base frame is disposed under a water tank, a top box is disposed on the water tank, and the base frame includes a coil box and a coil holder. The coil holder is disposed on the coil box, and an outer diameter of the coil holder is smaller than an inner diameter of the coil box, to form a gap between the coil box and the coil holder to dispose a first coil around the coil box. The first coil can generate electromagnetic induction when being energized. The first coil surrounds an outer side of a bottom of the water tank, and a second coil is disposed around an inner periphery of the top box, so that the first coil can generate electric energy through electromagnetic induction and transfer power to multiple devices.

Abstract: A wireless induction lamp includes a transmitter device for emitting wireless electric energy to a lamp receiver device, and the lamp receiver device includes a lamp housing having a transparent part disposed thereon, and a wireless light emitting device is disposed inside the lamp housing and in the transparent part. A first induction coil is disposed around on an outer edge of the wireless light emitting device, and receives the wireless electric energy of the transmitter device, to provide electric energy to the wireless light emitting device to emit light. The wireless induction lamp can wirelessly transmit electrical power to the light emitting element to emit light, so as to reduce disposal of electric wires, and the wireless light emitting device can be turned on/off by just changing a posture angle of the lamp housing to move close to or away from the electromagnetic range of the transmitter device.

Abstract: An ink composition for producing a color filter is provided. The ink composition comprises a colorant, a binder and plural solvents. A color filter production method using the above-mentioned ink composition is also provided. The ink composition is adhered to the designated light transmitting regions on the surface of a transparent substrate. Then, the ink composition adhered to the designated light transmitting regions is solidified.

Abstract: A structure of an ink-jet printer head of a piezoelectric type comprising a deformable polymer membrane, an actuator and an ink tank is provided. The deformable polymer membrane covers the top opening of the ink tank to enclose the ink tank. The actuator, which is a double-layer piezoelectric ceramic plate, is mounted on the deformable polymer membrane with one end thereof being fixedly connected to the polymer membrane and the other end thereof being free to vibrate. As a double-layer piezoelectric ceramic plate is employed as the actuator, it includes a top and a bottom piezoelectric layers. A predetermined voltage signal is applied selectively across the upper-surface electrode and the lower-surface electrode of the top and bottom piezoelectric layer respectively such that the top piezoelectric layer extends and the bottom layer shortens selectively.
