摘要： While a recording sheet is passing through a fixing nip formed between a heating roller 41 having a heating layer and a pressing roller 42 pressed against the roller 41, a coil 43 is exited by high-frequency power from a power source and causes the layer to generate heat. An unfixed image on the recording sheet is fixed by the heat. The power source detects a zero cross timing of a rectified alternating current, detects an instantaneous value at a point a predetermined period after the zero cross timing, calculates an effective power of the alternating current based on the instantaneous value, and controls the output power to be a desired value determined based on the effective power and the surface temperature of the roller 41. Thus power input to the power source can be quickly detected and power output to the coil can be quickly and stably controlled.

摘要： A metal gasket for sealing a three-component joint structure in which first and second joint members are disposed in confronting relation so as to align their respective holes with each other and in which an outer peripheral portion of a third joint member is fitted in a recess in the confronting surface of the first joint member. The metal gasket has an opening and is adapted to be placed between the first and second joint members so as to align the opening with the holes of the two joint members. The metal gasket also has, at a position near the opening, a stepped portion defined by first and second bends engageable with the first and second joint members, respectively, as the metal gasket is placed between the two joint members. As the first and second joint members are tightened so as to clamp the third member and the metal gasket, the stepped portion is deformed so as to bring the second bend to a position confronting the third joint member.

摘要： Super-resolution processing is regarded as a kind of intersample interpolation process and performed by using a linear interpolation filter designed according to sampled-data control theory. In an error-system model used in the process of designing the filter, a pre-filter is disposed before a sampler and a post-filter is disposed after the zero-order hold in a signal restoration system. At least either one of the characteristic Q(s) of the pre-filter or the characteristic P(s) of the post-filter is designed to be a low-pass characteristic, whereby the gain of the characteristic K(z) of a digital filter within a middle-to-high frequency range is raised. Raising the gain makes jaggies more prominent. To reduce this effect, in an actual processing system, the image to be processed is passed through a low-pass filter to reduce high-frequency components before the linear interpolation is performed.
