Abstract: An improved toy gun bullet container structure includes a bullet container device, which is selectively and movable mounted in a magazine, a receiving space, which is defined in the bullet container device, and a plurality of bullet compartments, which are arranged in the receiving space in a manner of being free to rotate. The bullet compartments each receive and hold therein a plurality of bullets. The magazine is can be mounted and removed so as to achieve imitation of a genuine device. When one of the bullet compartments runs out of bullets, the magazine can be first removed and the bullet container device rotated to switch the other one of the bullet compartments to the position for shooting. When all the bullet compartments run of bullets, the bullet container device can be detached from the magazine for reloading of bullets.

Abstract: A toy gun magazine module includes a magazine body having a gas storage space, gas inlet in communication with the gas storage space and check valve set configured on the gas inlet; the check valve set allows the gas inlet to be in normally closed state, and may be acted to open to allow the unidirectional input of high pressure gas in gas storage space to provide firing power. When the input of the high pressure gas is stopped, the check valve set is closed, preventing the high pressure gas from flowing reversely to leak out, thereby allowing the direct gas filling and repeated use of the present invention.

The system includes an air feeding member, an air inlet duct connected to one end of the air feeding member, an air filter connected to one end of the air inlet duct, a throttle disposed on the air inlet duct and located in front of the air feeding member, a test fixture for fixing an object under test connected to a front end of the throttle and a flow sensor disposed between the test fixture and the air filter. The object under test is fixed for measurement. A mode of sample set-up or a mode of product comparison is selected and various items including heating curve, static voltage, floating voltage, acceleration curve, intake temperature, thermistor, atmospheric pressure, velocity curve, etc are measured in turn. Thus a voltage-type measurement procedure is complete.

Abstract: A cartridge loading mechanism of a toy revolver includes a magazine, a cylinder, a cartridge drum and a driving element. When loading bullets, the cartridge loading mechanism may be removed to load the bullets. When firing a bullet, the cylinder may be rotated to provide a high simulation. When a bullet is fired, the cylinder and the cartridge drum are rotated together, and the magazine disposed in the cylinder and an inner magazine tube remain still and will not rotate with the cylinder, so that the inner magazine tube is aligned precisely with the barrel to improve the shooting accuracy.

Abstract: This invention is related to a non-contact sensor device for electric throttle, comprising a body and a cover. A drive assembly is set in the body and has a shaft corresponded to the on/off state of a throttle valve. An adaptor is installed on the shaft, and a magnet element is set on the adaptor. A Hall element is set on the cover to correspond to the magnet element for detecting the rotation angle of the shaft, thereby knowing the air inflow value and the open angle of the throttle valve to control the fuel injection of fuel-air mixture.

Abstract: A frequency test method of an airflow machine for measuring flow data of an air flow meter is disclosed. A device under test is fixed on the airflow machine to test. In the frequency test method, a sampling program or a comparison program is chosen, and then a data is measured sequentially, which data comprises the value of static frequency, accelerating curve, air charge temperature, thermistor, atmospheric pressure, flow curve, and frequency amplitude, completing a frequency test procedure. Therefore, after the air flow meter is tested, the scale of the air flow meter is kept in standard scale to use.

Abstract: A mass airflow meter is installed in the main intake passage of an internal combustion engine (ICE) and comprises an auxiliary passage and two sensors positioned in the auxiliary passage. The two sensors are connected to a control circuit which controls the air intake based on results measured by the sensors. The auxiliary passage comprises three paths. The first and third paths are paralleled and interconnected with each other through the second path positioned above them. An entrance of the first path is lower than that of the third path, thereby reducing the mixed flow of air and increasing the air flow rate through the guide of the auxiliary passage. The accuracy of the measurement of the air intake is increased by the sensors positioned correspondingly to the entrance of the first and third path to increase the fuel and air combustion efficiency is to elevate the horsepower of the ICE.

Abstract: Methods and apparatus for testing a semiconductor structure requiring a precise core or operating voltage with an OBIRCH analysis arrangement. The separate power supply used for providing the precise core or operating voltage is eliminated, and is replaced by connecting a circuit comprised of a plurality of Schottky diodes connected in series across the constant voltage power supply used to provide the current for the OBIRCH analysis. A precise voltage is then tapped from an anode of the series connected Schottky diodes thereby significantly reducing effects of background noise on the OBIRCH analysis.
