Abstract: In a display for measurement devices for use in displaying a pointer image of a measurement, a movement of the pointer image is smooth and a visual perception of the pointer image is improved. As shown in FIG. 1A, a display segment group S formed of sub pointer image display segment columns is arranged along scales M in a semicircular shape (a fanwise shape). The pointer image P is made of four sub pointer image display segment columns Sx+1 to Sx+4. In case the pointer image P is moved from the position marked by the bold solid line to that represented by a bold dashed line, a new pointer image is made of sub pointer image display segment columns Sx+2 to Sx+5. In other words, the pointer image is moved in a unit of a sub pointer image display segment column.

Abstract: A fluorescent luminous tube includes a plurality of cathode filaments, a multiplicity of a cathode wirings, each cathode wiring including one or more terminal portions and a wiring portion and being formed of a metal layer, and one or more intermediate portions, each being made of a metal layer. The cathode filament is grouped into at least one set of one or more filaments and filaments in each set are connected in series by fixing an end portion thereof on a terminal portion or an intermediate portion by ultrasonic wire bonding or ultrasonic bonding.

Abstract: A piezoelectric device and method comprising a piezoelectric vibrating reed 10 and excitation electrodes which are mounted in a package having a package base 42 and outer terminals using a TAB tape 20 composed of a plurality of electrical conductors formed on an insulating material with each of the plurality of electrical conductors disposed in an arrangement forming predetermined winding patterns 30 thereon with the wiring patterns 30 interconnecting the excitation electrodes to the outer terminals.

Abstract: A field emission image display is provided that can obtain a suitable white balance even when the luminous brightness of fluorescent substances is different. When an image is displayed on a field emission display (FED) panel based on input image data, correction data for correcting image data for each color is previously stored into the look-up table 33 to set properly the white balance in each gray scale of a display image to be displayed on the FED panel. The white balance of a display image to be displayed on the FED panel is nearly maintained to a constant value by correcting image data to be input using the correction data stored in the look-up table 33.
