Title: Fixing device
Inventor: NAGAFUJI HIDEO
IPC: G03G15/20
Filed: 1990-09-26
Abstract: PURPOSE:To accurately prevent the offset with a simple constitution by coating a heat roll and a pressure roll with a fluoride resin of high resistance and making a cleaning pad, which is pressed to the heat roll, of a felt member of high resistance. CONSTITUTION:The surface of the core bar of a heat roll 21 is coated with a fluoride resin 34 of good releasability and high resistance, and that of a pressure roll 22 is coated with an elastic member 36 of high resistance, and its surface is coated with the fluoride resin 34 of good releasability and high resistance, and a cleaning pad 23 is made of a felt member 38 of high resistance, and they are set to the non-grounded state. Since the fluoride resin is negatively electrified, the fluoride resin 34 on the heat roll 21 negatively electrifies the pressure roll 22 of high resistance and the felt member 38 of high resistance. Consequently, negatively electrified toner is hardly stuck to the heat roll 21, and toner is more hardly stuck because surfaces of rolls 21 and 22 have a good releasability and no minute flaws or the like. Thus, the offset of negatively electrified toner is accurately prevented.

Title: Face discharge type ac plasma display panel
Inventor: NAGANO SHINICHIRO
IPC: H01J11/42
Filed: 1995-10-03
Abstract: PROBLEM TO BE SOLVED: To reduce the effective area of discharge by replacing a part of a cathode film with a discharge inert film, and to improve contrast by reducing the maintenance discharge currents per pulse and increasing the maintenance discharge currents. SOLUTION: An MgO pattern 4a, which functions as a discharge cathode, is made on a discharge inert film 11. Therefore, the discharge inert film 11 fronts on the discharge space only at the gap section between the MgO patterns 4a, and the MgO pattern 4a is made on the gap inside each pair of maintenance discharge electrodes across a dielectric layer 3 and a discharge inert film 11. Here, in the region where discharge inert material is arranged on the surface, this does not cause discharge easily even by voltage application, and the MgO pattern 4 causes discharge with relatively lower voltage. This way, the maintenance discharge current per pulse is reduced and the maintenance discharge pulses are increased by reducing the effective area of the discharge, whereby contrast is improved, and wrong discharge between adjacent line is prevented.

Abstract: PROBLEM TO BE SOLVED: To provide a radio circuit of an orthogonal modulation/demodulation system capable of reducing the number of frequency dividers system, thereby reducing circuit scale and power consumption. SOLUTION: This circuit is provided with a local oscillation part 1 of a PLL frequency synthesizer system, a reception frequency converter 8 converting a reception signal into a reception intermediate frequency signal with the output of the local oscillation part 1, a frequency divider 2, which frequency-divides the output of the local oscillation part 1 by two and outputs the signals of two systems with a 90 deg. phase difference and an orthogonal demodulator 9, which orthogonally demodulates the reception intermediate frequency signal into a base band signal. The signals of the two systems from the frequency divider 2 are inputted to the orthogonal demodulator 9 for orthogonally demodulating the reception intermediate frequency signal.  One signal from either system in the two systems from the frequency divider 2 is inputted to the local oscillation part 1 as the signal of the comparison frequency of the local oscillation part. Thus, the frequency divider 2 is shared as the frequency divider of the local oscillation part and the orthogonal demodulator, and power consumption is reduced.
