Title: Optical clockface
Inventor: MURATA YASUSHI
IPC: G04B45/00
Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To provide an optical clockface whose apparent color varies depending upon the observing angle so as to improve the decorativeness of the face by providing a color control layer which controls the optical paths of incident light and outgoing light and a coloring means layer. SOLUTION: The main body 13 of the optical clockface 11 is constituted by successively stacking a coloring means layer 14 and a light control layer 15 from the inside of the main body 11 of a clock. The layer 15 is formed by shaping the front face of a colorless transparent platy member into a three-dimensional shape (triangular pyramid, quadrangular pyramid, hexagonal pyramid, etc.) on one side or both sides. The layer 14 is formed by using a colored plastic plate which colors when the plate absorbs light. The external light made incident on the main body 11 from the outside is controlled in optical path by means of the layer 15 and the incident light in a certain direction is mostly reflected to the outside from the main body 11. The incident light in another direction is mostly transmitted through the main body.  The outward color of the main body nearly becomes the color of the external light in the reflecting direction and the color of the colored light in the transmitting direction. Therefore, the decorativeness of the clockface 13 is improved, because the color of the clockface 13 varies depending upon the observing angle from the outside or the clockface 13 becomes invisible or visible.

Abstract: PURPOSE:To prevent a rear electrode and a linear hot cathode from approaching to each other and effectively modulate an electron beam using low modulation voltage by arranging the linear hot cathode at the off-axis position in relation to the permeation hole of the electron beam extraction electrode, and applying modulation voltage to the rear electrode or the electron beam extraction electrode. CONSTITUTION:A linear hot cathode 10 is arranged at the off-axis position in relation to the permeation hole 18 of an electron beam extraction electrode 12. That is to say, when the linear hot cathode 10 is projected on the electron beam extraction electrode 12, a part of the projection point PO is made to slightly cover the permeation hole 18, but not fully. An electron radiated from the linear hot cathode 10 passes through the permeation hole 18 of the electron beam extraction electrode 12 while its amount is being controlled depending on the negative potential applied to a rear electrode 11. An electron beam can fully be modulated by applying low modulation voltage to the rear electrode 11 using the double peak characteristics of the electron density distribution on the surface of the electron beam extraction electrode 12, when the potential of the rear electrode 11 is varied.
