C. to make carbon fibers, pulverizing the carbon fibers to make carbon fiber particles, heat treating the carbon fiber particles at a second temperature greater than the first temperature thereby providing carbon fiber particles with a layer spacing between carbon layers of less than 0.338 nm and an average particle size of 5-200 .mu.m.
摘要:
While a drain power source of a reset transistor and a drain power source of an amplifying transistor are separated, the load of drain power source can be reduced by sharing a drain diffusion layer of the reset transistor and a drain diffusion layer of the amplifying transistor and a pixel amp transistor by adjacent cells in sharing pixel units. Further, it is possible to perform layout setting for the floating diffusions such that parasitic capacitances between the floating diffusions are equal to each other. It is possible to prevent step-like noise from occurring among the pixels while improving sensitivity.
