Title: Color picture tube
Inventor: KUDOU MAKOTO
IPC: H01J29/07
Filed: 1982-04-16
Abstract: PURPOSE:To prevent any extension of slit holes located in the periphery of a shadow mask by forming bridges through the process of connecting them together, while said bridges vertically separate slit holes positioned on the phosphor screen side of the shadow mask, by means of connection grooves each having concave parts on its both ends. CONSTITUTION:A shadow mask 4 is positioned between an electron gun and a phosphor screen which is by laying a phosphor stripe 3 on the inner surface of a panel 1. It is formed by connecting adjacent slit holes on the side of the phosphor stripe 3 to each other by means of each connection groove 12, and by providing concave parts 13 on both ends of the groove 12. Here, the concave parts 13 are located at almost the same level as the thickness of bridges which vertically separate the slit holes, and the thickness of the concave parts 13 is controlled by the concave degree of the parts 13. Therefore, variations in the desired thickness and width of the bridges can be reduced. As a result, any unevenness of the form and quality reduction, and any extension of slit holes located in the periphery of the shadow mask 4 which might be caused after the formation of the mask 4 can be prevented.

Title: Double speed angle reader
Inventor: SHIMIZU TAKASHI
IPC: G01B7/30
Filed: 1980-05-14
Abstract: PURPOSE:To adjust the phase of a double speed angle reader accurately and easily by adding digital offset quantity to the fine and coarse double speed angle reader. CONSTITUTION:Such precision digital offset quantity that makes the display quantity of a precision digital angle display device 22 zero is fed from a digital quantity input device 21 via a fine-coarse coupler 23 by closing a test switch.

Title: Scanning electronic microscope and operation method therefor
IPC: G01N23/22
Filed: 1992-03-19
Abstract: PURPOSE:To provide a high-performance scanning electronic microscope which is equipped with a secondary electron detection system capable of trapping secondary electrons with high efficiency from low acceleration voltage to high acceleration voltage, and which is small in terms of the deflection quantity of primary electrons and astigmatism. CONSTITUTION:When a primary electron beam 1 is radiated onto a specimen 3, secondary electrons 2 emitted therefrom move upwards while making spiral motions. After having been moved away from an objective lens, the secondary electrons diverge quickly as a result of a decrease in the magnetic flux density and are deflected by a drawing field from a secondary electron detector 4, and thus are trapped in the same. In order to prevent the primary electron beam 1 from being exposed to the drawing field from the secondary electron detector 4 and thereby deflected, a shield electrode 8 is provided which has an opening permitting transmission of the secondary electron 2 therethrough, by which the secondary electron 2 is not obstructed by the shield electrode 8 and is trapped into the secondary electron detector 4. This enables large reduction in the deflection quantity and astigmatism of the primary electron beam so that deterioration in yield of the secondary electron is prevented. As a result, it is possible to realize a high-performance scanning electronic microscope with high resolution and high sensitivity.
