Title: Reset circuit
Inventor: AOKI KANJI
IPC: H03K3/02
Filed: 1988-11-18
Abstract: PURPOSE:To simplify a latch circuit and to reduce the size of a chip by using the edge of a reset signal as data for the latch circuit storing data for controlling hysteresis, generating a pulse, inputting it as a clock and causing the latch circuit to fetch the clock. CONSTITUTION:Since the output of a shift register takes AND with the output 7 of a pulse generation circuit 6, input data of a latch circuit group 9 comes to L when the output 7 is L. Since the pulse generated in the pulse generation circuit turns into the latch input of latch circuit groups 9 and 10 as an output 14 when input data 15 comes to L, latch data in L is transferred. Data 16-18 stored in respective latch circuit groups are inputted as data of selectors 11, and they select one out of signals 12a-12d controlling the state of an output driver 13. Consequently, the size of the chip is reduced because all the latch circuits are not required to be the circuits with reset.

Abstract: PURPOSE:To easily attain the high precise preparation of analytic elements only by designating the number of division of each boundary line by a user by calculating a parameter for gradually changing the size of the analytic element based on the shape of an area to be analyzed. CONSTITUTION:An area analyzing part 21 analyzes the shape of the boundary line in the area to be analyzed, and a parameter calculating part 22 calculates the parameter necessary for gradually changing the size of the element.

Then, the average of the length of the temporary elements of the entire boundary lines connected at each vertex is searched, and the division ratio of each boundary line is calculated from the length of the entire vertex elements. The division ratio is the ratio of the length of the side of the element at the start edge point side of the boundary line to that at the end edge point side, and the parameter is necessary for searching a common ratio from both the ratio and the number of division, and operating a division so that the length of the side of each element can be a geometrical progression. Thus, the dividing processing is operated by an element dividing part 23.
