IPC: H01J9/22
Filed: 1992-07-30
Abstract: PURPOSE:To reduce thermal decomposing temperature in panel baking process and improve the luminance of a cathode-ray tube by using a polyalkylene carbonate as a filming agent used in the manufacturing process of the cathode-ray tube. CONSTITUTION:At manufacturing a cathode-ray tube, a phosphor screen is formed on a panel inner surface, a filming agent consisting of a polyalkylene carbonate (e.g. polyethylene carbonate) is applied onto the phosphor screen to flatten the surface. The polyalkylene carbonate is used in the form of the emulsion decomposed and emulsified in an organic solvent, or in the form of the emulsion decomposed and emulsified in a water solvent under the presence of an emulsifier. A metal such as aluminium is then evaporated on the filming agent layer followed by baking, and the organic component is thermally decomposed to manufacture a cathode-ray tube. Thus, the thermal decomposing temperature in baking process can be reduced lower than in the past, and the formation of the baking remainder of the film after baking can be eliminated.

Title: Motion detector
Inventor: KAMEI MASANORI
IPC: A63B71/06
Filed: 1990-08-23
Abstract: PURPOSE:To provide data for measuring accurate momentum by providing an acceleration sensor for detecting the acceleration of a motional body and a motion judging means for comparing the output value of the acceleration sensor with a threshold value to judge the type of motion of the motional body. CONSTITUTION:The drawing shows the output value of an acceleration sensor 1 provided on one's arm to be swung. The dotted line shows the output value when one walks and the solid line shows the output value when one runs. A horizontal line X between the maximum value A of the solid line and the maximum value B of the dotted line is determined by a threshold value determining device 3 to show a threshold value used by a judging device 4 which judges that one is running when the maximum value A is larger than the threshold value X and that one is walking when the maximum value A is as small as the maximum value B. However, since one differs in the stature and the output value of the acceleration sensor varies with the distinction of sex even in the same motion, the threshold determining device 3 corrects the threshold value X on the basis of data of the stature or the like from an input device 2 to improve the accuracy.
