IPC: H05K1/00
Filed: 1997-12-16
Abstract: PROBLEM TO BE SOLVED: To provide a method and device for efficiently controlling signal line impedance of a circuit board. SOLUTION: In this control method of the signal line impedance of an electronic circuit board by changing the characteristics of a lattice-formed earthing surface, an earthing surface 60 is arranged adjacent to and in parallel with the signal line surface of the circuit board, and the earthing surface is composed of conductors 61 of a lattice-like pattern. There conductors 61 form a number of lattice elements 68. In order to form the impedance of the signal line, corresponding to the earthing surface, to the desired value, the size of the lattice elements on a part of the earthing surface is changed along the parts 62, 64, 66 and 70 of the length of the signal line. The change in size of the lattice elements 68 may be based on the appropriate combination of tilt function, stepwise function, square-waved function and other functions.

Title: Lighting-direction-variable dc lighting metal halide lamp
Inventor: TAKITA KAZUO
IPC: H01J61/52
Filed: 1997-12-16
Abstract: PROBLEM TO BE SOLVED: To provide a metal halide lamp with a long life, high color rendering and high efficiency whichever direction it is mounted. SOLUTION: Discharge medium containing Cs halide is filled in a luminous tube 2 in which a cathode 8 and a anode 9 are opposed to each other and a cylinder 3 is arranged to encircle the luminous tube 2, the luminous tube 2 and the cylinder 3 being stored and held with an outer tube. When a metal halide lamp is mounted with the cathode 8 directed downward and lit on in a direct current, a temperature around the cathode 8 is increased by the heat of infrared ray emitted from the vapor of the Cs halide gathered around the cathode 8 with high density. When the metal halide lamp is mounted with the cathode 8 directed upward, a temperature around the cathode 8 is prevented from being increased more than required by the heat of the infrared ray emitted from the vapor of the Cs halide because the density of the halide gathered around the cathode 8 is reduced.  The lighting-direction property of the metal halide lamp is thus improved.
