A heating device includes a belt member that is rotated, plural heating elements that are arranged in a width direction of the belt member and generate heat so as to heat the belt member, plural resistance elements that have positive temperature coefficients and are connected to the plural heating elements such that each of the plural resistance elements is connected in series with a corresponding one of the plural heating elements, and a base material that includes a heat-conductive metal layer and a pair of heat-resistant metal layers between which the heat-conductive metal layer is interposed and has a surface on which the plural heating elements and the plural resistance elements are disposed. A temperature of the belt member is reduced by an increase in resistances of the plural resistance elements caused by an increase in temperatures of the plural resistance elements.

A fixing device includes a heating rotation body, a heat source and a pressurization member. The heating rotation body has an endless peripheral surface that moves circularly. The heat source heats the heating rotation body. The pressurization member is in pressure-contact with the peripheral surface of the heating rotation body to press a recording medium, which passes through a nip between the pressurization member and the heating rotation body, against the peripheral surface of the heating rotation body. The pressurization member includes a base material and plural layers deposited on the base material. A volume resistance of a surface layer forming a surface of the pressurization member is larger than that of a layer disposed just below the surface layer. The layer disposed just below the surface layer is grounded.

Data separating means extracts intra-frame or intra-field encoded blocks from an intra-frame or intra-field encoded, and inter-frame or inter-field encoded digital video signal, and a digital audio signal contained in an input bit stream. Error correction code appending means appends error correction codes to the extracted intra-encoded blocks. Recording means records the data having the error correction code appended, in special replay data recording areas predefined on the magnetic recording tape. During fast replay or slow replay, error correction is achieved even for the replay signal with a low output level and a poor symbol rate.

In a digital VTR having a certain recording bit rate, within a range not higher than a remaining data rate after recording the bit stream, first HP data Dis recorded in first specific regions, and second HP data Dis recorded in second specific regions in specific tracks. In middle-speed and high-speed fast replay, the magnetic tape is transported continuously at a middle-speed or high-speed higher than the standard speed for normal replay, and the first HP data Dis used in common, and at a low-speed fast replay of about twice the normal speed, the speed of the magnetic tape is alternated between a speed near the standard speed for normal replay, and a speed near the low-speed fast, and at the speed near the standard speed, the second HP data disposed in the second specific regions in the specific tracks and the first HP data disposed in the first specific regions in the specific tracks are both replayed.

To provide a fixing device which can suppress the occurrence of a temperature droop phenomenon, and to stably peel off a recording sheet from a fixing roll side. There are provided a fixing belt module and a pressure belt module, and the fixing belt module and the pressure belt module are in contact with each other through a fixing belt and a pressure belt in a first nip portion formed on a fixing roll around which the fixing belt is wound and a second nip portion formed on a pressure roll around which the pressure belt is wound.

A method of forming an insulating ceramic film or a metallic film by a plasma CVD process in which a high density plasma is generated in the presence of a magnetic field wherein the electric power for generating the plasma has a pulsed waveform. The electric power typically is supplied by microwave, and the pulsed wave may be a complex wave having a two-step peak, or may be a complex wave obtained by complexing a pulsed wave with a stationary continuous wave.

Pulsed plasma CVD method for forming a film

A digital VTR for magnetically recording and replaying a bit stream, includes a detector, an extractor, a mode designator, and an output unit. The detector detects intra-picture data in the bit stream being replayed from tracks in a magnetic medium. The extractor extracts the intra-picture data from the bit stream based on output from the detector. The mode designator designates one of a normal replay and a slow replay as a replay mode. The slow replay is replay performed at a speed slower than normal replay. The output unit stores the extracted intra-picture data, and outputs only the extracted intra-picture data as replay picture data when the slow replay mode is designated.

An image forming apparatus includes an image carrying body, a heating unit, a pressure unit for applying pressure, a recording medium supporting member, and a depressing/close-contacting unit. The recording medium supporting member moves in the same direction as the image carrying body moves, from a pressure position where the pressure unit applies pressure to the recording medium and the image carrying body to an exfoliation position where the recording medium is exfoliated from the image carrying body while supporting the recording medium overlapped with the image carrying body. The depressing/close-contacting unit sandwiches and depresses the recording-medium supporting member and the image carrying body in a middle position between the pressure position and the exfoliation position to closely contact the recording medium with the image carrying body.
