Abstract: A flourescent luminous type display device capable of providing display at increased luminance while being simplified in structure. An insulating substrate constituting a vacuum airtight envelope is laminatedly formed on an inner surface thereof with cathode electrodes and emitters in order. Another insulating substrate is laminatedly formed on an inner surface thereof with an anode electrode and phosphor layers. The phosphor layers contain a secondary electron emission material.

Abstract: An optical printer including a fluorescent light-emitting tube equipped with an anode in a form of dot and a rotatable rotating filter part equipped with filters R, G, B. A film is moved relative to the optical printer set at a given position. A controlling device rotates the rotating filter part, and, in synchronization with that, the fluorescent light-emitting tube is made to emit light by the image signal of every color of red, green and blue. The image can be formed by moving the film one time relative to irradiation with the light in a state of a dot transmitted selectively through each filter of red, green and blue. Since the head is fixed and the film is moved, room for the movement of the head which has been conventionally required is not required. Spatial room for the slide of the filter is not required differently from the slide-switching type-filter of the conventional art.

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.

Abstract: A flat antenna with a simplified feeder point is provided. The flat antenna consists of a round patch antenna section, a dielectric material, a grounded conductive plate. The patch antenna section is arranged so as to confront the grounded conductive plate via the dielectric material. The center conductor of a coaxial cable is inserted into the opening formed in the grounded conductive plate and further penetrates the dielectric material of a thickness of t. The center conductor is electrically connected with the feeder point P of the patch antenna section. The outer conductor of the coaxial cable is connected to the grounded conductive plate. The center conductor has the inductive impedance L added by the penetration length of the dielectric material. Improved matching characteristics can be provided by setting the resonance frequency of the patch antenna section to a higher frequency than receive frequencies and by adding a capacitive impedance to the impedance of the feeder point.

The luminous efficiency of a field emission display (FED) prepared employing the Y2SiO5:Ce phosphor was measured at an anode voltage of 600V, an electric power input of 30 Wp-p and a duty rate of 1/240.

Abstract: A receiving system or a received radio-wave estimation method is provided that can maintain received field strengths at a nearly uniform level under multipath conditions. The antenna switch 41 can select outputs of four antennas at high speed (where n=4). The high-frequency amplifier 42 amplifies the output of the antenna switch 11 and the demodulator 42 demodulates amplified signals. The matched filter bank 45, surrounded with chain lines, receives a demodulated signal, for example, the I-phase component. In the matched filter bank 45, the phase shifter &phgr; shifts respective signals output from four delay elements (r1, r2, r3, and r4). The adder (Ka, . . . , Kp) synthesizes the phase-shifted signals and then supplies the maximum matched output to the maximum level selector 46.
