Title: Solid state image pickup device
Inventor: MURAKAMI SHINICHI
IPC: H04N5/359
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To give some allowance for voltage setting of a substrate at incorporation into a system by lightening the dependency upon the substrate voltage of the output signal level of a solid state image pickup device. SOLUTION: A solid state image pickup device equipped with light receiving regions 11 arranged in matrix form and vertical transfer parts 15 consisting of second p-type wells 13 and n-type layers 12 arranged in the horizontal transfer direction of these light receiving regions 11 have a p-type semiconductor layer 13a between the light receiving regions 11 adjoining each other in vertical transfer direction. This p-type semiconductor layer 13a narrows the low- concentration region right under the light receiving region 11, restrains the charge accumulated in the light receiving region 11 from being swept out to the side of the substrate, lessens the change of the output signal level of the solid state image pickup device to the change of the voltage applied to the semiconductor substrate, and gives some allowance for setting of substrate voltage.

Title: Synchronizing clock generating circuit
Inventor: MAEDA YUKINORI
IPC: G03G15/04
Filed: 1987-12-18
Abstract: PURPOSE:To shorten a synchronizing time and to reduce dispersion by executing the sampling of an input signal with the rising and falling of an original clock, obtaining two dividing clocks and causing a logical OR to be a synchronizing clock. CONSTITUTION:A first dividing circuit 6a is operated by the rising of an original clock CLK and a second dividing circuit 6b is operated by the falling of the original clock CLK. Accordingly, when the logical OR between first and second dividing clocks CL1 and CL2 is obtained by an OR gate 6c, a synchronizing clock CLS, which goes to be 'high' by the rising of the second dividing clock CL2 and goes to be 'low' by the falling of the first dividing clock CL1, can be obtained. A synchronizing time Td is not over 1/2Ts+alpha(<=1/2 of the period of the clock CLK) and the synchronizing time Td can be widely shortened. Thus, in a laser printer, the time dispersion goes to be small and a jitter can be decreased.
