Title: Ceramics discharge lamp and lighting system
Inventor: HONDA HISASHI
IPC: H01J61/88
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a ceramics discharge lamp having excellent condensing property by providing a lens part, which can be easily manufactured, in an outer surface of a discharge container of ceramics. SOLUTION: A discharge container 2 of ceramics is formed into a hollow cylindrical shape, and formed with a lens part 5 in the periphery opposite to a discharge space, in which electrode structures 8 are arranged with a space at 0.5-9 mm. The lens part 5 is formed so that thickness thereof is formed at the maximum at a near a central part of an outer surface of a discharge space of the discharge container 2 and that thickness is reduced, as it comes close to both ends of the discharge container 2. Since the discharge container 2 is formed into the cylindrical shape, the lens part 5 can be easily manufactured by flowing the molten ceramics into a space between an inner frame, which forms a hollow part, and an outer frame, which forms the lens part 5, for solidification.  The lens part 5 deflects the outgoing direction of most of the beam, which is emitted in a discharge hollow part 3 of the discharge container 2, to the central side of the lens part 5 for condensation. Luminous intensity of distribution of the condensed outgoing light of the lamp 1 is controlled by an optical system such as a reflecting mirror.

Abstract: PURPOSE:To provide a reflection type liquid crystal display device having excellent reflex characteristic by forming the sectional shape of a reflector out of fine convexities of doughnut-shape or mixture of circular-shape and doughnut- shape, and arranging the convexities irregularly. CONSTITUTION:A pair of transparent boards 31 face to each other sandwiching a liquid crystal layer. An insulating film 42 having irregularity is applied to a liquid crystal layer side on one of the boards 31, and thereon plural reflex electrodes 38, being display picture elements reflecting incident light from the other board side, are formed, and a common electrode, having translucency on nearly the whole face thereof, is formed on the liquid crystal side of the other board 31 so as to form a reflex liquid device. In the reflex liquid device, the sectional shapes of protrusions are a fine doughnut-shape 42a or mixed with a circular-shape 42b, and the arrangement thereof is irregular. As an irregular portion is formed by using a mask, the shapes, particularly the depths of dents are uniform.

Abstract: PURPOSE:To improve visual ascertainment of abnormal display, by a method wherein, through computing of a microcomputer, abnormality is displayed by means of a staged change in color tone called a change in the background color of a CRT display surface and a change in a car speed display color. CONSTITUTION:For example, when the temperature of cooling water is increased to an abnormal value, a microcomputer 70 decides abnormality by means of a signal from a water temperature sensor 20, produces data which changes the background color of a display surface 91 of a CRT 90 from a grey color to a red color, and performs red display of the periphery thereof togetherwith digital green display of a car speed through a controller 80. In which case, a vehicle is brought to a stop, but if no level change occurs to a signal from a car speed sensor 10 through a shaping circuit 50, overheat and the necessity of engine stop are displayed by means of a synchronizing signal. In case a vehicle is left to run as it is, a car speed display is changed from a green color to, for example, a black color. This permits improvement of visual ascertainment of abnormal display.
