Abstract: A vacuum large-capacity electrically controlled proportional valve includes a main body having a valve bottom seat, a middle valve seat, and a guide seat and has a vacuum pressure chamber, in which a main diaphragm is arranged with an elastic element provided thereon to connect with the guide seat. A pilot discharge straight rod is fit to a center of the main diaphragm. The main body includes a master channel connected to a guide channel and a feedback channel Provided above the guide seat are a vacuum pressure electromagnetic valve, an atmospheric pressure electromagnetic valve, and a sensor. The guide seat includes a regulation channel connected to the vacuum pressure chamber. A pilot atmosphere channel is connected to a space under the main diaphragm. A first and a second vacuum destruction valve gates are provided and driven by an external atmospheric pressure for speeding up decrease of interior vacuum level.

Abstract: A vacuum electrically controlled proportional valve includes a valve seat coupled to a guide seat. The guide seat is connected, at a top thereof, to a vacuum pressure electromagnetic valve, an atmospheric pressure electromagnetic valve, and a sensor. A main diaphragm is sandwich between the seat valve and the guide seat to define a vacuum pressure chamber. A pilot discharge straight rod that is provided with a vacuum valve gate assembly is fit to a center of the main diaphragm. A master channel through which a primary-side pressure and a secondary-side pressure flow is provided. A regulation channel is provided and controlled by the vacuum pressure electromagnetic valve and the atmospheric pressure electromagnetic valve. A pilot atmosphere channel is connected to a space under the main diaphragm. A first and a second vacuum destruction valve gates are provided for adjusting, in stage-wise manner, the level of vacuum pressure.

Abstract: The present invention provides a method to treat asthma and airway allergy by administering the dipeptide cyclo tyrosine-valine or a related cyclodipeptide compound to a subject in need thereof. Cyclo tyrosine-valine or the related cyclodipeptide compound reduces Th2 cell activation, airway hyperresponsiveness, accumulation of immune cells in bronchoalveolar fluid, and allergen-specific antibody production in an animal or human subject. The compound can therefore be used to treat asthma and airway allergy.

Abstract: A drive assembly of an electric bicycle is disclosed. A shell tube of an electric bicycle is transfixed with a crank shaft sheathed with an outer shaft set. The outer shaft set links to a tubular motor set. A first side of the crank shaft is provided with a left positioning set sheathed and limited in a left hole of the shell tube. A second side of the crank shaft is provided with a right positioning set sheathed and limited in a right hole of the shell tube. The right positioning set is fixed with a chain wheel set. A displacement of the crank shaft pulled by a bicycle chain is detected by a torque detection unit, and a torque is accessed by a control unit based upon the displacement to control the output power of the tubular motor set, thereby assisting pedaling the bicycle with feet.

Abstract: A gas valve consists of a valve body. The valve body includes an inlet passage and a pilot passage. Said pilot connects to the inlet passage and a pilot ignition device set outside the valve body. Gas is led into said valve body through the inlet passage, passing said pilot passage, and is brought into the pilot ignition device. Said gas valve is characterized in that two solenoid valves are installed in the pilot passage. Said solenoid valves can open and shut the pilot passage, and when one of the solenoid valves function incorrectly, another valve will serve as an auxiliary, impeding the gas flow being delivered to the pilot ignition device, improving safety measure of the gas valve.

Abstract: The present invention discloses an organic light emitting diode display, a driving method therefor and a pixel unit thereof. The organic light emitting diode display comprises a pixel array comprising a plurality of organic light emitting diode (OLED) pixel groups of different colors, such as red, green and blue. The organic light emitting diode display can determine the ratio of shortened light emission intervals of OLED pixel groups of a specific color based on the color distribution of an image, thereby effectively prolonging the life of the OLEDs of a specific color. In one embodiment, the pixel unit of the organic light emitting diode display comprises an OLED, a switch and a drive circuit. The switch controls whether or not the current outputted from the drive circuit flows to the OLED so as to achieve the effect of the above-mentioned shortened emission interval.

Abstract: A touch display device, a touch display system, and a method for adjusting a touch area thereof are disclosed. The touch display system comprises a computer system and the touch display device. The touch display device provides a touch area with a touch control function. The method comprises following steps: receiving an image signal and displaying an image representing the image signal on the touch display device; detecting and obtaining a signal resolution of the image signal; detecting and obtaining a display status displayed by the touch display device, wherein the signal resolution and the display status are used to determine the boundary of the image; determining whether the touch display device simultaneously displays the image and an inactive area, wherein the inactive area is the region where the touch display device does not display the image; and if yes, adjusting the coordinates of the touch area such that the touch area and the image correspond with each other.
