Abstract: PROBLEM TO BE SOLVED: To realize the suppression of poor electrification such as uneven electrification of a body to be electrified or the like and consequently the acquisition of a favorable image by a method wherein a flexible electrode for discharging and a flexible insulating member, which locates between the flexible electrode for discharging and the body to be electrified and contacts with the surfaces of the body to be electrified, are equipped under the condition that the standings on the frictional electrification series of a contacting surface and of the surface of the body to be electrified are different from each other. SOLUTION: An electrically conductive member 110 and the electrically conductive base 10a of a body to be electrified 10 are grounded. Printing voltage corresponding to a recording image are applied from a printing voltage application part 100 to a flexible electrode 12. The materials of the contacting portion between a flexible insulating material 11 and the body to be electrified 10 and of a dielectric layer 10b are selected so as to make the standing of the contact portion between the flexible insulating member 11 and the body to be electrified 10 on the frictional electrification series different from that of the surface of the body to be electrified 10 on the frictional electrification series.  As a result, through the frictional electrification between the flexible insulating member 11 and the body to be electrified 10, the flexible insulating member 11 and the body to be electrified 10 are charged to polarities different from each other and attract to each other, resulting in bringing an electrifying member 1 in closely contact with the unevenness of the surface of the body to be electrified and keeping the distance between the discharging end part 121 of the flexible electrode 12 and the body to be electrified 10 constant.

Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To radiate high-intensity and high-brightness high-frequency electromagnetic wave by forming light radiation parts in diamond film with poly-crystal diamond. SOLUTION: A poly-crystal diamond film 2 and an overcoat a diamond layer 4 are radiated with stimulation light 5. A KrF laser of 2ps pulse half-width is used as stimulation light. When the diamond film 4 is radiated with the stimulation light 5, electrons and electron holes are produced as light carriers. The light carriers move in the poly-crystal diamond film 2 or in the overcoat diamond layer 4. The more carriers produced and the larger number of carriers reaching electrodes 3 emitting high-frequency electromagnetic wave, the higher- intensity high-frequency electromagnetic wave 10 is produced. Since the diamond crystal exhibits higher dielectric breakdown voltage than other semiconductor materials, a high voltage can be applied between electrodes and a high- brightness high-frequency electromagnetic wave can be emitted at the time of stimulation light radiation.

Abstract: PROBLEM TO BE SOLVED: To manage both the tracking accuracy of tracking double-tuned filters and the oscillation purity of local oscillators by making the tracking double- tuned filters control a resonant frequency based on a control signal for a filter which is generated different from a control signal for the oscillators. SOLUTION: Tracking double-tuned filters 3, 7, 8 and 12 on an RF stage have their passband controlled not by a control signal for an oscillator of local oscillators 15 and 16 for IF signal generation but by a control signal for a filter which is different from the control signal for an oscillator. That is, a direct current voltage signal from a DA converter block 50 is given to the four filters 3, 7, 8 and 12 and four matching circuits 4, 6, 9 and 11 on the RF stage. Then, it is possible to avoid such a case in which oscillation purity of the oscillators 15 and 16 is sacrificed in order to protect the tracking of a center frequency of the filters 3, 7, 8 and 12 against an oscillation frequency of the oscillators 15 and 16.
