Filed: 1985-09-26
Abstract: PURPOSE:To make it possible to arrange grids unrestrictedly, by preparing grid compositions connected each other with very small bridges, and furnishing adhesive pieces to be heat-adhered to the grid compositions. CONSTITUTION:After piling a pad 14 connected to a wire 13 and a heat-adhesive piece 15, laser beams are applied on them to fix the grid composition to a vacuum envelope 11, and an electric potential can be given to the grid 12 from spacer leads 17 through pads 18 and the wire 13 with the pad 14. After that, bridges 16 connecting the grids are burned out by the laser beams to insulate between the grids. In this case, if the grids and the other parts are blackened responding to the wave length of the laser, the heat absorption is improved to improve the process efficiency. In this case, the bridges are treated in consideration totally to prevent the deformation of the grids before the heat-adhesion. In such a composition, grid-to-grid distance can be realized to be about 1.5mm longitudinally and laterally.

Filed: 1989-08-21
Abstract: PURPOSE:To prevent malfunction owing to the bound of a handset and the vibration of a mainbody by making chattering supervisory time longer than that in the other state at the time of holding. CONSTITUTION:When a holding button 5 is depressed in a communication state after the connection of a line with an opposite destination is completed by the response of an opposite party after dial origination, the input signal C of the holding button 5 comes to a low level in an instant, and an output signal D for a holding circuit 3 comes to a high level, whereby a system comes to an off-hook holding state. When the handset is on-hooked and a hook switch 6 is opened in the off-hook holding state, a hook switch signal A comes to the high level and the system comes to an on-hook holding state after chattering supervisory time t2 passes. Then, the chattering supervisory time of the hook switch 6 is made long only at the time of the holding state. Thus, the malfunction of releasing holding owing to vibration can be prevented.
