Title: Inspection device for cathode-ray tube
Inventor: MUTO SATOSHI
IPC: H01J9/42
Filed: 1988-03-07
Abstract: PURPOSE:To improve the reliability of inspection by conducting the inspection using a light source of the illuminance of 2000lux or greater from behind a cathode-ray tube with its phosphor surface formed with a metal back layer. CONSTITUTION:The forming condition of a metal back layer on a panel 1 of a cathode-ray tube is inspected from the front of the panel 1 by opening a shutter 4 by the operation of a switch 5 to illuminate the panel from behind. As a light source 3, a light source for exposure ordinarily used for forming phosphor surface is suited. This light source is a high pressure mercury-vapor lamp of 2000lux or greater, about 1kW, 3000lux for example, having sufficient capacity to satisfy the purpose. The illuminance of 2000lux or greater is preferable because the forming condition of the metal back layer is hard to observe in detail under the condition of a shadow mask installed, if the illuminance of the light source is below 2000lux.

Abstract: PROBLEM TO BE SOLVED: To prevent a piezoelectric body from being damaged, even if shock is applied to it from a fall or the like by forming it so that a stress distribution is nearly uniform in shape when a dynamic load is applied. SOLUTION: A piezoelectric body 110 is formed into a shape, where a stress distribution when a dynamic load is applied is nearly uniform in shape, namely in a thick-board shaped bimorph type where the thickness of a central part is thicker than an outer-periphery part and is provided with electrodes 114 and 115 that are formed on the surfaces of two piezoelectric plates 112 and 113 which adhere to the front and back surfaces of an intermediate electrode 11 connected to a rechargeable system 180.  In this case, when the thickness of the central part of the piezoelectric body 110 is made thicker than that of the outer-peripheral part, namely in a think board shape, the piezoelectric body 110 becomes storage against shocks, and the stress at the central part also becomes larger than that in the outer-periphery part, consequently, the stresses applied to each part of the piezoelectric body are averaged so that piezoelectric body is prevented from being damaged due to the concentration of partial stresses.

The min. component value is  subtracted from the respective three color component values by a subtactor 7, by  which the much more distinctly discriminatable ratio is obtd. This is subjected to ratio operation or the like in an arithmetic processing circuit 8, whereby the color discrimination is accomplished.
