A method of manufacturing a MOS transistor device is provided. First, a semiconductor substrate having a gate structure is prepared. The gate structure has two sidewalls and a liner on the sidewalls. Subsequently, a stressed cap layer is formed on the semiconductor substrate, and covers the gate structure and the liner. Next, an activating process is performed. Furthermore, the stressed cap layer is etched to be a salicide block. Afterward, a salicide process is performed to form a silicide layer on the regions that are not covered by the stressed cap layer.

An H-shaped vertical axis type windmill structure comprises a mainshaft on the top end of which is disposed a rotary shaft by a bearing. On the top and lower ends of the rotary shaft are disposed a support bracket and a support base, and in the middle of the rotary shaft is a connecting member. The support bracket, support base and the connecting member are connected to the connecting arms, and the other ends of the connecting arms are fixed to vertical blades. The connecting arms enable the blades to be vertically connected with the rotary shaft, and the mainshaft is not rotatable and serves as a stator of the generator structure. The vertically arranged straight and flat blades are easy to manufacture and fabricate and can be made of composite material for purpose of lightweight.

The automatic audio playing device mainly contains a hollow body member, a control unit housed inside the body member, a plug member and a speaker as integral parts of the body member, an adaptor, and a remote controller. The control unit has a radio reception circuit for receiving control signals from the remote controller. The control signal is forwarded to a signal processing circuit, which in turn triggers a microprocessor in accordance with the control signals. The microprocessor instructs an audio playing circuit to play an appropriate digital audio file via the speaker. The plug member could be plugged into a conventional lamp socket for a light bulb, or the plug member is first plugged into the adaptor and the adaptor is then plugged into a conventional wall socket. Once this is done, the automatic audio playing device could be turned on and off by switches of existing wiring.
