A film adhering mechanism includes a base, a film adsorbing platform, at least two flexible members, a vacuum generator; and an electromagnetic valve. The assembly includes a wiper arm having a first end and a second end. Thus the method effectively controls credit consumption and achieves the object of precise allocation of processor resources. The gasket includes a circumferential sealing ridge and finger gripping recess. The FET stack is doped to form a gate electrode and the resistor stack is doped aside from the resistor portion thereof. Phase errors depending upon temperature, aging and reception power can be entirely eliminated by the invention in electro-optic distance measuring devices.
