A counter weight flywheel includes an inner cylindrical body and an outer cylindrical body disposed between an upper faceplate and a lower faceplate. A shaft tube is positioned in the inner cylindrical body, and plural tensile bars are inserted in the inner cylindrical body, respectively having one end secured on the fixing members of the shaft tube and the other end fixed on the inner wall of the outer cylindrical body. Plural reinforcing bars and plural reserve tubes are respectively fixed between the inner and the outer cylindrical body. A counter weight area formed between the inner and the outer cylindrical body is filled up with concrete or iron sand, and the inner cylindrical body has its interior forming a hollow area. Thus, the counter weight flywheel is made by combining iron plates and concrete or iron sand.

An energy-saving environmentally friendly generating system includes at least one starting system, a generating system, a transmission gear system, and at least one weighting system. Speed ratios of the transmission gear system are utilized, and an external power is used to start the starting system. The speed changes of large and small gears create torques for releasing energy that is multiple times of the primitive energy of the starting system. The weighting system rotates and creates a gravitational force to release multifold energy for counterbalancing the load of generating and the load of electricity consumption of the generating system. The generating system can thus be started. When the generating system reaches its rated generating speed, a portion of electricity is directly transmitted to the starting system, thereby achieving continuous operation for generating electricity.

A centrifugal driving electricity generation system for energy conservation comprises a kinetic energy driving system powered with electric energy or fuel energy, an impelled rotary system, a gearing wheel group system, at holder, and a power generation system. In the principle of contrast between centrifugal and application of force, the lower kinetic energy driving system drives the impelled rotary system from a centrifugal terminal to make an effect of centrifugal force, which amplifies multiple times the original energy of kinetic energy driving system and makes the system link with a gearing wheel group system through an axis portion of the impelled rotary system to drive the higher power generation system to operate at a high speed for power generation at a rating rotation speed. Thus, the lower kinetic energy driving system may be used to drive the higher power generation system to generate electricity for achievement of energy conservation.

A method for dicing a wafer including the following steps is provided. First, a carrier tape is attached to a first side of the wafer. Then, a patterned photoresist layer exposing a scribe line region of the wafer is formed on a second side of the wafer, in which the second side is the opposite side of the first side. After that, a cutting process is performed to the scribe line region from the second side of the wafer to the first side of the wafer through non-mechanical force.
