摘要:
Disclosed is a six-bar linkage positioning mechanism mounted inside a clean container formed of a locating member and a four-bar linkage and a driving module which, when moved, has the slide of the driving module stopped at the base of the cleaning container and be forced to move upwards relative to a sliding way inside the locating member and to cause the driving link of the driving module to drive the four-bar linkage upwards and to further force the second link of the four-bar linkage to push workpieces in respective insertion slots in a cassette on the clean container. The six-bar linkage positioning mechanism has only one degree of freedom so that it moves workpieces horizontally in the cassette into position by means of contact at a point, preventing contamination due to friction and also improving moving stability.

The disclosure provides a compensating design method for a shadow mask including: providing a first shadow mask having a first opening pattern and a first material pattern; disposing the first shadow mask on a substrate having a predetermined depositing film area with first and second sides; performing a deposition process by using the first shadow mask as a mask to form a film on an actual depositing film area, wherein the distance between the first and the third sides is a first bias, and the distance between the second and the fourth sides is a second bias, and a single side gray zone of the actual depositing film area relative to the predetermined depositing film area is substantially half of the sum of the first and the second biases; and designing a second shadow mask according to the single side gray zone.

A memory access interface for connecting a memory to a micro-controller having an address/data multiplexing bus and a microprocessor is proposed The memory access interface includes an address latch, a multiplexer, and a data buffer The address latch latches and outputs the lower-bit address signal on the address/data multiplexing bus of the micro-controller when an address-latch-enable signal is enabled. The multiplexer receives the lower-bit address signal latched by the address latch, a higher-bit address signal outputted from the micro-controller and an address signal outputted from the microprocessor and selectively outputs the address signal of the micro-controller or the address signal of the microprocessor as the address signal of the memory according to a first control signal. The data buffer transmits the signal of the data bus of the memory to the address/data multiplexing bus of the micro-controller during a data cycle of the micro-controller and maintains a high impedance state during an address cycle of the micro-controller.
