Abstract: PROBLEM TO BE SOLVED: To prevent direct collision of an electrified particle, to improve the life and reliability of an electron source, by providing a support composed of two-layer different kind materials, and a shield plate so as to cover an electron emitting element, on a wiring on an element substrate. SOLUTION: Supports 7 and 17, composed of two layers, are formed on an X-direction wiring, and moreover, a shield plate 8 can be formed, so as to cover an electron emitting part 15, on the support 7 and 17, thereby protecting an electron emitting element from a positive ion. The supports 7 and 17 are composed of different kind materials, and one side and the other side layers are insulating and conductive materials respectively. An electron, emitted from the emitting part 15, can pass through an electron opening part 10 formed on the shield plate 8 to reach an acceleration electrode 13 which is an opposite electrode; and moreover, can pass through the opening part 10 to reach a face plate, to make a phosphor 12 luminous, thereby displaying a picture image.  Here, making one side layer 7 of the stanchion into a conductor can decrease the deflection of an electron beam, and forming other side layer 17 of an insulating material can obtain a withstand voltage property, thereby forming a surface to be flat at a fixed height.

Title: Vulcanization of rubber extrudate
Inventor: IWASA TADANOBU
IPC: C08J3/24
Filed: 1986-02-08
Abstract: PURPOSE:To form a beautiful skin on the sponge seal part of a sulfur- vulcanizable rubber extrudate stably, by previously applying a specified amount of a heated softener or plasticizer to the sponge seal part in vulcanizing the sulfur-vulcanizable rubber extrudate. CONSTITUTION:In vulcanizing a sulfur-vulcanizable rubber extrudate W fitted with a sponge seal part 1, a softener (e.g., aromatic process oil) or a plasticizer (e.g., dibutyl phthalate, heated to 80-300 deg.C) is previously applied to the surface of the sponge seal part 1 of the unvulcanized rubber extrudate W. The amount of the softener or the plasticizer applied should be such that it is diffused into the rubber and does not remain on the surface when the vulcanization is completed. The vulcanization is completed by heating at normal pressure for a definite time. In this way, it is possible to obtain the sponge seal part 1 of a fine skin because the heated softener or plasticizer is applied to the surface and the vulcanization of the surface occurs earlier by this heat to form a skin layer not affected by foaming.

Abstract: PURPOSE:To reduce the quantity of a software required for a transmission processing and to shorten a time for the transmission processing, by converting a single-pole NRZ signal to an AMI signal with a 50% of pulse duty ratio by a hardware. CONSTITUTION:To an NRZ signal having waveform (a), a reference clock having waveform (b) is outputted from a reference clock generating part 1. The AND of the waveforms (a) and (b) is taken by an AND circuit 6, thereby, a single-pole RZ signal with the 50% of pulse duty ratio shown in waveform (c) can be obtained. Waveforms (d) and (e) show the output waveform of a 2-frequency demultiplier 7 and its inverted output waveform, and a level is inverted at every trailing edge of the waveform (c). Therefore, waveform (f) in which the AND of the waveform (c) and the waveform (d) is taken by an AND circuit 8, and waveform (g) in which the AND of the waveform (c) and the waveform (f) is taken by an AND circuit 9 go to H levels alternately in a term where the waveform (c) is set at an L level. Since a transistor 10 is turned ON in the term where the waveform (f) is set at the H level, a negative pulse is transmitted to a line side, and since a transistor 11 is turned ON in the term where the waveform (g) is set at the H level, a positive pulse is transmitted to the line side.
