IPC: G09F9/00
Filed: 1977-12-27
Abstract: PURPOSE: To increase the reliability of vertical conducting agent, and enhance the commercial value of display element by extending the display effective area, by using conductive paste mixed with low melting point conductive metal as the vertical conducting agent of electrode substrates.  
     CONSTITUTION: An upper substrate 1 having an upper electrode 3 of specified shape in the inside, and a lower substrate 2 having a lower electrode 4 which confronts against the electrode 3 are fused and secured together in the circumference with sealing agent, and the electrode extending outside is connected to the terminal of the substrate 1. The electrodes 3, 4 are connected by means of a vertical conducting agent 6 which has low melting point metal such as Sn and In of which melting point is 100 to 300°C added and mixed in silver paste. The low melting point metal is melted by thermo-compression-bonding of the sealing agent 5 to set up a pole between electrodes 3, 4. Therefore, the area and volume of conduction between electrodes 3 and 4 are sufficiently larger than those of silver paste, so that failure of conduction due to distortion and warp of substrates 1, 2 may be prevented.

Title: Transfer material transferring and separating method for image forming device
Inventor: ITO NOBUYUKI
IPC: G03G15/14
Filed: 1991-06-07
Abstract: PURPOSE:To eliminate the need of applying an excessive current so that discharge may be stabilized in the case of separation and to simplify the constitution of a separating means by impressing a high frequency AC voltage lower than the discharge start voltage of all the members other than an image carrier ground electrode as separation bias. CONSTITUTION:When a transfer material reaches a separation part where an image carrier is opposed to a separation electrode, the separation bias having interpeak voltage 6kV and obtained by superposing DC on AC is impressed on the electrode by an AC power source and a DC power source. The positive charge of the transfer material is neutralized and destaticized, and the transfer material is separated from the image carrier by elasticity and stiffness of its own and carried to a fixing part. Relation between the frequency of the AC power source and a separation difference current is as shown by figure. Namely, it is known that faulty separation occurs when destaticization is too weak and toner is retransferred when it is too strong, but a range where such a failure does not occur, is widened by making the frequency high. In the case of impressing 6kV on the electrode, discharge is performed only toward the image carrier, and a discharge wire in an exposed state is used.
