Title: Pulse generator
Inventor: ITO HISAHARU
IPC: H03K7/08
Filed: 1989-07-15
Abstract: PURPOSE:To realize a double setting precision and to reduce the cost by providing a half clock control circuit which properly shifts the rise of a ripple carry signal by a half clock with a half clock control signal to generate a trigger clock signal. CONSTITUTION:When a half clock control signal HALF is in the high level, a half clock control circuit 6 shifts to right the rise of a ripple carry signal RCY by a half clock. Therefore, the high level section and the low level section can be controlled by the precision of the half clock of a clock signal CLK, namely, the double precision. For example, the high level or low level section is widened by an extent corresponding to the half clock of the clock signal CLK in comparison with that set by section setting data when the half clock control signal HLF is in the high level. Thus, the setting precision of the high level or low level section is raised twice without raising the frequency of the clock signal CLN, and the cost is reduced because this device is formed with inexpensive circuit elements.

Abstract: PURPOSE:To form a filter with a high accuracy integrally with components of even a complicated structure, such as a device of every type, by a method wherein a large number of pores based on microballoons are formed and connected to each other so that liquid can pass through a resin layer. CONSTITUTION:In the production of a filter, firstly microballoons 52 are dispersed in curable resin 51 serving as a binder resin by a generally used homogenizer or the like. The microballoon-containing curable resin dispersion is heated to an appropriate temperature so that the microballoons can expand to a required size. A volatile content of cores 53 is vaporized by heating, thereby expanding the microballoons. Next, in this state, the binder resin 54 is cured. A shell resin in a cured state is eluted in a slovent, such as acetone, whereby pores 55 are formed. Then, the forming of the filter is completed.
