Abstract: PROBLEM TO BE SOLVED: To provide a method of leveling ink on a substrate and an apparatus useful in printing.SOLUTION: An exemplary embodiment of the method includes irradiating ink 144 disposed on a surface of a porous substrate 140 with radiation emitted by at least one radiant energy source. The radiation heats the ink to at least a viscosity threshold temperature of the ink to allow the ink to flow laterally on the surface to produce leveling of the ink. The ink is heated sufficiently rapidly that heat transfer from the ink to the substrate is sufficiently small during the leveling that ink at the substrate interface is cooled to a temperature below the viscosity threshold temperature thereby preventing any significant ink permeation into the substrate.

Abstract: PROBLEM TO BE SOLVED: To prevent a fault or distortion in printing by preventing the occurrence of a position mismatch or distortion of a recording medium caused by a roller or a belt for feeding/discharging the recording medium in a printer. SOLUTION: An air bearing paper feeding/discharging element 1 for improving feeding/discharging of recording paper in a printer is disposed upstream of an image transfer station 3. Compressed air is discharged from a line of holes 20, thereby generating an air cushion. When the recording paper 2 moves in a paper feeding/discharging path, the recording paper 2 is stuck to a paper feeding/discharging belt 4 or a drum.

Abstract: PROBLEM TO BE SOLVED: To provide the row and column bistable array which is controlled with reliable passive matrix addresses. SOLUTION: The array includes cantilever bistable valves 10, which each have an opening 29 determined and have electrically conductive switching elements 17 and 18 in a housing 12; and the switching electrodes are arranged adjacently to or opposite the opening. Electrically conductive bistable cantilever beams 13 for blocking the determined opening are mounted in the housing and mounted on the respective valves. The bistable cantilever beams can be switched between a stable opening blocking position 15 and a stable opening open position 13.

Abstract: PROBLEM TO BE SOLVED: To provide a pneumatic actuator imitating the muscle. SOLUTION: This pneumatic actuator includes a first pressure source, a second pressure source lower than the first pressure source, at least one expansion chamber 24 alternately conducting with the first and second pressure source, a first and second valves fitted to printed circuit boards 13, 15 to open and close to the first and second pressure sources, and an actuator member interacting with the expansion chamber to apply force to an object. The actuator is preferably formed by a plane batch technique, the valve preferably includes an electrically controlled flap valve fitted on the printed circuit board. Instead of that, the actuator includes expansion chambers disposed opposite to each other, and the chambers have the operation for applying the reverse force to the object.

Abstract: PROBLEM TO BE SOLVED: To provide a precise and compact roller assembly simple in handling a soft sheet material like paper. SOLUTION: An opening part 18 communicated selectively to a vacuum source or a pressure source on an outer surface of a roller assembly 10. This opening part 18 is directed to a direction along a rotation axis of a roller and gives a vertical speed component in the tangential direction of surface speed of the roller to paper. Additionally, alignment of the paper is improved by connecting this opening part 18 selectively to the pressure source and the vacuum source, and as it is possible to save plural paper delivering parts, to change various speed of the roller or to reverse the paper, it is possible to print on a first or second surface.

Abstract: PROBLEM TO BE SOLVED: To provide the mass measuring system, which automatically detects the property of a paper sheet and automatically adjusts the setting of a paper- sheet conveying mechanism. SOLUTION: This system 140 includes an actuator 141, a paper-sheet-position sensor 142 and a touch-sense sensor system 200. The actuator 142 applies known force on a paper sheet 150, moves the paper sheet 150 and passes the paper sheet to the paper-sheet-position sensor 142. The paper-sheet-position sensor 142 measures the speed of the paper sheet 150 at each point. The paper sheet 150 passes the touch-sense sensor system 200. Thus, the friction coefficient of the paper sheet is measured. A controller can measure the mass of the paper sheet 150 by using these measured values. This is utilized, and the performance of the paper-sheet carrying path in a copying machine or the like is changed.

Abstract: PROBLEM TO BE SOLVED: To provide an actuator containing a pneumatic expansion type elastomer membrane, laminated on a printed circuit substrate and pressurized and decompressed by utilizing an electrostatically driven flap valve.
SOLUTION: The flap valve obtains a high pressure regarding a closing pressure and a holding pressure since the flap valve is closed only when a pressure gradient and a flow are zero. Fluid extracted from the elastomer membrane is discharged through the wall of the actuator while shrinking. An air jet type object moving device opens and closes an air hole for air jet by utilizing array of the pneumatic pressure actuator as a valve. An optical fiber microswitch positions a mirror by utilizing the pneumatic pressure actuator.

Abstract: PROBLEM TO BE SOLVED: To provide an improved method and equipment of cutting objects. SOLUTION: A member 10 to be cut is bonded to a template 16, and then the aperture formed in the template is irradiated with a laser 36 so as to cut the member without crossing the template to obtain desired formed bodies 13, 15. Since the laser does not cross the template, the template is not cut, thereby causing no excess laser cutting dust. COPYRIGHT: (C)2003,JPO

Abstract: PROBLEM TO BE SOLVED: To provide a flap valve suitable for adjusting the flow of a liquid. SOLUTION: This flap valve structure has a valve support structure including an orifice (hole) for adjusting the flow of the liquid. A flexible flap valve element is arranged for covering the orifice (hole) to open or close the orifice. The flexible flap valve element has first and second terminals. The first terminal is fixed to the flap valve support structure with a clamp member, and the second terminal of the flap valve is bound by at least one flexible cord-like tethering section practically narrower in width than the first terminal of the flap valve. The cord-like tethering section is extended and stretched from the second terminal of the flexible flap element and connected to the flap valve support structure. A control device is connected to the flap valve structure to selectively hold the flexible flap valve element at an opening/closing position covering the orifice.
