Embodiments of the present invention are directed to providing a leakage detecting method for use in an oxidizing system of forming an oxide layer so as to shorten leakage detecting time period. In one embodiment, a leakage detecting method for use in an oxidizing system of forming an oxide layer comprises performing oxidizing processes on a plurality of test wafers in a plurality of test runs under a specified operating condition in an oxidizing system having an oxidizing chamber to form oxide layers on the test wafers having a plurality of oxide thicknesses for the plurality of test runs by flowing an oxidizing gas through the oxidizing chamber containing the test wafers. An oxygen concentration of the oxidizing gas exiting the oxidizing chamber is measured in each of the plurality of test runs. The method further comprises obtaining a correlation between the measured oxygen concentrations and the oxide thicknesses for the plurality of test runs to identify a threshold oxygen concentration corresponding to a maximum acceptable oxide thickness. An oxygen concentration greater than the threshold oxygen concentration indicates gas leakage in the oxidizing system.

The antiseptic wound dressing includes at least nanometer chitin, alkaline earth metal alginate, and an antiseptic material. The nanometer chitin is tubular shaped having diameter 10˜50 nm and length 20˜200 nm. The amount of the nanometer chitin is 0.1%˜5% to the alkaline earth metal alginate. The antiseptic wound dressing is manufactured by mixing nanometer chitin and alkaline earth metal alginate, further mixing with antiseptic material, conducting a wet spinning process to produce fibers, and conducting a non-woven cloth process to obtain the antiseptic wound dressing of the present invention. Therefore, the antiseptic wound dressing is capable of reducing the chance of would infection, and providing superior moisture retention and enhanced wet strength.

A vehicle window structure for preventing a person from being thrown out, applied to a vehicle, includes a fixing frame. An inner frame surface of the fixing frame is provided with a plurality of fixing portions spaced apart from each other. An arresting net includes at least one plastic rope fixedly connected to the fixing portions in an interlaced manner. The fixing frame is provided with a light-permeable unit that is mounted and fixed within the inner frame surface and covers the arresting net. When the vehicle has an accidental rollover unfortunately, even if the light-permeable unit is damaged or the fixing frame is deformed during the overturning of the vehicle, the arresting net is still able to arrest the user effectively because the arresting net is directly fixed to the fixing frame, thereby preventing the user from being thrown out of the vehicle.

A gas control valve featuring magnetic control and a gas ignition system having the same are disclosed. The gas control valve includes a main body and a magnetic control assembly. The main body has a valve base and a control lever. The control lever is movably connected to the valve base. The magnetic control assembly has a magnetic member and a magnetic control switch. The magnetic member is installed in one of the valve base and the control lever, while the magnetic control switch is installed in the other of the valve base and the control lever. When the control lever moves to an ignition position, the magnetic control switch is affected by the magnetic member and forms a closed circuit. The magnetic control assembly is incorporated in the gas control valve in a modularized manner, and can be easily maintained and repaired.

A forming method for a cooling system of a rapid heating mold comprises: preparing a solid cooling waterway object (30) of a default cooling waterway, the solid cooling waterway object (30) comprising multiple interconnected attachment portions (31) and multiple subbranch portions (32); placing the solid cooling waterway object (30) into a container (40) provided with a perfusion groove (41), and the attaching the attachment portions (31) onto a groove bottom surface (411) of the perfusion groove (41); preparing a perfusion material, and perfusing the perfusion material into the perfusion groove (41) of the container (40) to form a mold fixing layer (50) of the solid cooling waterway object (30) after cooling; and taking out the mold fixing layer (50), heating the mold fixing layer (50), enabling the solid cooling waterway object (30) to be in a gas state or a liquid state, and discharging the object in the gas state or the liquid state, so as to form a cooling waterway (52) corresponding to the solid cooling waterway object (30). Accordingly, a cooling waterway in any form can be formed on the mold upon needs, and the effects that the cooling waterway is easy to treat and the heat dissipation temperature of the mold is uniform are achieved.
