Abstract: Thermoelectric materials based on tetrahedrite structures for thermoelectric devices and methods for producing thermoelectric materials and devices are disclosed.

Abstract: The present disclosure provides a gate turn on voltage compensating circuit, a display panel, a driving method and a display apparatus thereof. The gate turn on voltage compensating circuit includes a voltage generation module, a clock control module and a chamfering module. The voltage generation module is used for correspondingly outputting generated first voltage signal and second voltage signal to a first voltage input terminal and a second voltage input terminal of the chamfering module; the clock control module is used for controlling the chamfering module to output corresponding chamfered voltage signals in the corresponding time periods, so that the chamfering depths of gate turn on voltage signals input correspondingly to respective gate drive chips in different time periods are different.

Abstract: An attaching apparatus (10) includes a guiding bracket (30), a pivot bracket (40), and a sliding bracket (50). The guiding bracket includes a supporting plate (312), and a first table (32) defining a first space (322). The pivot bracket includes a pivot device having a connecting plate (42) and a pivoting plate, the pivoting plate is pivotably connected to the connecting plate. The sliding bracket slidably engages with the guiding bracket. The first table is movably positioned on the supporting plate. The first table under the first space defines one or more suction holes. The pivoting plate includes a second table (430), and two locators (440, 450) movably positioned on the second table. The second table defines one or more suction holes (434). The attaching apparatus can be readily adjusted to attach LCD panels and polarizers of various different sizes.

Abstract: This device is related to the domain of fully automatic machines for oil extraction. An axle transmission and soft belt suspension system is used in the device. A decelerator connects an electric motor and a driving hub, so that the transmission belt can be driven. When the driven hub and the bridle are connected, the sucker rod will be connected so that the oil-well pump can start working. There are several other units, an absolute value coder that can measure the driven hub's angle of rotation, a augmenter coder that can measure the rotational speed of the electric motor and an oil gauge. In the device, a oil production process controller processes collects signals and then the device controls the machine, the beam and the pump system automatically. It has the advantages of saving energy, high efficiency for oil extraction and long operational life span.
