  • Patent number: 7807261
    Abstract: A transparent conductive laminate consisting of a transparent polymer substrate, an uneven cured resin layer formed on at least one side of the substrate and a transparent conductive layer formed on the cured resin layer directly or through another layer. The cured resin layer contains fine particles A having an average primary particle diameter of 0.5 to 5 ?m and super fine particles C having an average primary particle diameter of 100 nm or less made of a metal oxide and/or a metal fluoride. The above transparent conductive laminate does not cause the deterioration of visibility by sparkling even when a transparent touch panel is mounted on a high-definition display and can prevent “Newton rings” which occurs between two transparent electrode substrates constituting the transparent touch panel.

  • Patent number: 4723855
    Abstract: A compact printer has a type drum having at least one row of types, the types, including at least one space, being arranged on the periphery of the drum at regular intervals. The type drum is rotated by a stepper motor and a hammer member is provided for moving a selected type towards the paper for printing. The stepper motor is turned by signals which correspond to each step necessary to move the type drum through at least one pitch distance between types. Ratchet teeth, moving with the type drum, can be engaged by a blocking lever when rotation of the type drum is reversed, so as to stop vibration of the type drum at the time of printing.

  • Patent number: 4402261
    Abstract: A printer mask has spaced openings to allow impact therethrough of a hammer against characters arranged in circular columns along a character drum. The distance between the characters and mask changes automatically to compensate for changes in ambient temperature by using mounting materials of selected thermal coefficients of expansion. Uniform printing quality without marring the print paper is achieved with this mask construction.

  • Patent number: 4387643
    Abstract: A small printer using character wheels is provided. The printer includes a plurality of character wheels frictionally mounted on a shaft for rotation therewith and having a ratchet wheel on side surface. Associated with each character wheel is a pivotable selector pawl actuatable by an electromagnet. The number of electromagnets is less than the number of selector pawls and character wheels. Stopper cams are actuatable into locking engagement with the ratchet wheels on even-numbered character wheels when the shaft begins to rotate. Only odd-numbered character wheels are caused to rotate with the shaft. The desired characters on the odd-numbered character wheels are selected when the electromagnets are energized selectively to move the selector pawls into locking engagement with the ratchets on the odd-numbered character wheels. During the next revolution of the shaft, the stoppers are retracted, that is, out of engagement with the ratchets on the even-numbered type wheels.

  • Patent number: 4373439
    Abstract: Character rings mounted on a common shaft and having a plurality of circumferential character columns thereon, are opposed by a platen including recessed portions. A recessed portion faces non-printing character columns when the platen presses against one character column on each character ring for printing on paper. The platen translates laterally so that each character column on a character ring is printed in sequence. A single character selection and return mechanism serves all columns on a single character ring. A translating mask separates non-printing characters from the paper.
