Abstract: An inkjet recording apparatus conducts image recording by ejecting ink and a reactive liquid that reacts with the ink onto a recording medium conveyed by an endless conveyor component. The inkjet recording apparatus includes: a dummy ejection controller that dummy-ejects one of the ink and the reactive liquid onto a first position on the endless conveyor component and dummy-ejects the other of the reactive liquid and the ink onto a second position on the endless conveyor component where the one of the ink and the reactive liquid is not adherent; and a cleaning device that cleans the ink and the reactive liquid on the endless conveyor component.

Abstract: A recording head includes: liquid discharge ports that discharge liquid and are arranged at a pitch corresponding to a resolution, wherein said liquid including an ink; plural drive elements that cause the liquid to be discharged from the liquid discharge ports in correspondence to the liquid discharge ports and are arranged at a pitch corresponding to the resolution; and plural drivers having voltage buffer regions for buffering effects resulting from a high voltage, said drivers being serially connected in a one-to-one ratio to, and unitized with, the drive elements, and being arranged at a pitch enlarged by at least the voltage buffer region portions with respect to the pitch of the drive elements, and driving the drive elements.

Abstract: An ink-jet recorder is disclosed which has an arrangement of a plurality of heat-generating elements, drivers for driving the heat-generating elements, and a drive circuit for controlling the drivers according to image data, wherein the drive circuit includes; a split-block drive circuit that divides the plurality of heat-generating elements into a plurality of blocks, and drives the heat-generating elements on a block-by-block basis in a time-sharing manner, and a data retaining circuit for retaining print data; and the split-block drive circuit that; drives each of the blocks of the heat-generating elements at printing operations, using a pre-pulse during which ink is not squirted and a main pulse during which ink is squirted; and drives another group of heat-generating elements differing from the currently-driven group of heat-generating elements, during intervals between the pre-pulse and the main pulse.

Abstract: A fuzzy logic circuit for operating a fuzzy logic with "fuzziness" taken into account has an operation section memory unit in which the result of operation to be outputted in response to an input is stored in an address specified by the input, the result of operation being rewritable, whereby the change in the contents of a fuzzy logic operation to be performed can be handled merely by rewriting the contents of the operation section memory unit.

Abstract: A road surface layer reproducing machine is characterized by its rotor unit which is provided with a mixing chamber housing the rotors for scarifying and mixing the asphalt pavement in an atmosphere of a high temperature higher than the temperature of open air to facilitate such a scarifying and mixing operation of the asphalt pavement, which mixing chamber is kept at such a high temperature by the operation of heating means such as a heater and a hot air blower, and is vertically driven through power cylinders.

Abstract: The paved road surface reproducing apparatus consists of first and second self-propelled, steerable working trucks. The first truck is equipped with: a road surface heater; a pair of gas cylinder tables mounted on both sides of the truck which can be raised or lowered by lifts; a hopper for receiving a bituminous mixture from outside; and a conveyor for transporting the mixture form the hopper to the rear part of the truck. The second truck is equipped with: a hopper for receiving the bituminous mixture transferred from the first truck; a conveyor for transporting the mixture received from the hopper to the rear part of the truck; a powdery oil-absorber scattering device to minimize rutting; a small size road surface heater; a scarifier; a softening agent scattering device; and a rotor; and also equipped with a first screw spreader; a first screed; a second screw spreader; and a second screed in tandem at the rear part of the truck.

Abstract: Disclosed is an automotive rolling machine having a main frame section and a lengthy roller equipped to at least one side of the main frame section. The roller is tapered at the outer peripheries of its end portions, whereby, at the time of changing the advancing direction of the roller, the paved surface is not damaged by the outer peripheral angular portions of the roller. The main frame section has a frame at the front and rear end portions of which slider guides are laterally equipped in such a manner that sliders are slidably fitted into the slider guides. At the central portions of the sides of the frame, center pins are vertically supported. And to the underside of the center pins are fixed the central portions of lower frame members supporting the rollers as viewed in the longitudinal direction. The front and rear end portions of the lower frame members are connected to the sliders so that the lower frame members may be movable with respect to the sliders. Thus, the machine has high steerability.
