Abstract: Holes 12 are created in a slab-shaped body 11. On the first surface 131 of the body 11, the holes 12 are arranged at the lattice points of a triangular lattice 141. On the second surface 132, they are arranged at the lattice points 122 located at positions corresponding to the gravity center of a triangular lattice 141. Three air columns 12A obliquely extend from each lattice point 121 to the nearest three lattice points 122. Similarly, three air columns 12A obliquely extend from each lattice point 122 to the nearest three lattice points 121. In this construction, a periodic structural unit 16 consisting of three holes is created within the body 11 and this unit has a C3v-symmetrical shape at any section 14 parallel to the body 11. Due to this symmetry and the obliquely extending form of the air column 12A, a complete PBG with a large width is obtained. In one embodiment, a broad complete PBG whose width equals 15% of its middle value is obtained.

Abstract: In a non-impact recording apparatus that includes a plurality of recording elements, there is provided a source of first data signals representing for each of plural pixels density, size or percentage of coverage for recording. A first look-up table memory is responsive to the first data signals for adjusting the density, size or percentage coverage of each of the pixels with a gamma adjustment related to density development by the apparatus and generates multibit gamma adjusted second data signals. A second look-up table memory generates a third signal related to a characteristic of the recording elements such as for nonuniformity correction. A process look-up table memory is responsive to the gamma adjusted second data signals and the third signals for generating fourth multibit signals relating to exposure on-times for recording pixels by the recording elements. The use of the three look-up table memories results in substantial saving in memory requirements.

Abstract: In a one-pass multi-head type color thermal printer having at least first to third printing stages arranged along a transport path, slacks are provided in the recording material between the first to third printing stages. The amounts of the slacks are measured by respective slack sensors. The transporting speed of the recording material through the second printing stage is fixed at a constant value, and the transporting speeds through the first and third printing stages are controlled in accordance with the outputs from the slack sensors, so as to maintain the amounts of the slacks constant. The slacks are provided during an initial loading of the recording material by delaying starting the transport of the recording material in downstream ones of the printing stages for a time after a leading edge of the recording material moves in each of the downstream printing stages until each of the slacks reaches a predetermined amount.
