Title: Look ahead circuit and method to which pulse is applied with synchronization
Inventor: JIEI EI MAKUSHII JIYUNIA
IPC: G06F7/00
Filed: 1991-12-25
Abstract: PURPOSE: To provide an improved look-ahead circuit and a system which reduce delay relating to a storage element while guaranteeing necessary synchronism with control clock pulses. CONSTITUTION: The look-ahead circuit 10 which synchronizes and is applied with pulses performs look-ahead operation for a flip-flop 20. To make the look- ahead operation start, an LAPP section 12 is triggered in synchronism with the control edge of a clock, activates an LAPP line, and places a data detection and control section 14 in operation. During the operation, data input is accepted and the flip-flop 20 latches the data according to its phase and when preparations for control over a data output line are made, the LAPP pulse ends after relative propagation delay. Then the data detection and control section 14 finishes operating and the look-ahead operation ends.

Filed: 1998-12-02
Abstract: PROBLEM TO BE SOLVED: To maximize display contract by using a scattering mode display element having higher transmission characteristics in a transmissive frontal direction than peripheral parts in the scattering state. SOLUTION: A scattering mode display element has a structure in which a composite body of a polymer 13 and a liquid crystal 14 or 14' is held between a pair of substrates 11a, 11b. In a polymer dispersed liquid crystal (a), the liquid crystal 14 is dispersed in the polymer as independent spheres, and in a polymer network type (b), the liquid crystal 14' forms a consecutive continuous body structure. Transparent electrodes 12a, 12b are formed on the inside surfaces of the substrates 11a, 11b and by applying a voltage the liquid crystal aligns in the same direction and the display becomes transparent. Consequently on/off of the voltage switches the transmissive/scattering state. Thereby higher transmission characteristics in a transmissive frontal direction than in peripheral parts are realized so as to improve the contrast and the display characteristics.

Abstract: PURPOSE:To remove two-component developer after development from a developing sleeve and to prevent the irregular density of a developed image and the deterioration of the developer by providing a magnetic member for removing the developer from the developing sleeve after it is induced and magnetized by a 1st magnetic pole. CONSTITUTION:A magnetic body 51 is arranged to be opposed to the sleeve 20 between the position of a magnetic pole N1 and a position P, and between the sleeve 20 and a screw 23. The magnetic body 51 is induced and magnetized by the magnetic pole N1 so as to form the magnetic brush of the developer between the sleeve 20 and the magnetic body 51. In such a case, repulsive magnetic field is formed, so that the developer is nearly perfectly removed from the sleeve 20 because the feeding force of the developer from the magnetic pole N1 to the magnetic pole N2 is weak from the beginning and the magnetic brush is formed. The developer removed by the magnetic body 51 drops on the screw 23 as shown by an arrow 11, and is taken in the screw 23. Namely, the magnetic body 51 has a function for mediating the transfer of the developer from the sleeve 20 to the screw 23.
