  • Publication number: 20210089146
    Abstract: An electronic pen includes a cylindrical housing including an opening on one end of the housing in an axial direction of the housing, a core body attached inside of the housing such that an end of the core body protrudes from the opening on the one end of the housing, and a signal generation circuit which, in operation, generates a signal that is transmitted from the core body. The core body includes a core rod that is conductive and a protection member. The core rod includes a front portion that protrudes from the opening on the one end of the housing, a back portion, and an intermediate portion between the front portion and the back portion. The intermediate portion has a tapered shape narrowing from the front portion toward the back portion. The core rod receives the signal from the signal generation circuit. The protection member covers a side surface of the intermediate portion of the core rod.

  • Patent number: 7903268
    Abstract: As a user selects one of error recovery methods for each error category, and the selected method is stored in a memory. When an error occurs, an error recovery method corresponding to an error category of the error is detected. If the detected method is automatic print continuation, then the error is ignored and print operation is automatically continued. If the detected method is a recovery by user's operation, then an error message is displayed, and a procedure is performed in accordance with an instruction from the user.

  • Patent number: 5449493
    Abstract: Piezoelectric elements are attached to both sides of a flexible metal thin plate, thus forming a bimorph-type piezoelectric vibrator. A portion of the metal thin plate is extended to form a stirring blade. A suitable weight is attached to a part of the metal plate such that the amplitude of the blade is made greater than the amplitude of the vibrator itself. The voltage to be applied to the vibrator and the frequency are adjusted, and the vibrator is vibrated in a second-order mode. Thereby, the entire solution is moved simultaneously, vertical motion is caused, and the stirring efficiency is enhanced.

  • Patent number: 4954743
    Abstract: This invention provides an igniter plug, having a plurality of grooves within an outer surface of an annular ground electrode (2), the diameter of which is reduced to about 13 mm. Each groove (6) generally has a semi-circular shape in cross section to allow air flow along the grooves (6), with the number of the grooves (6) in the range from 4 to 16, and the width of each groove is to about 1.0 mm to 2.5 mm. The semi-circular cross section of the grooves (6) makes it possible to provide a large surface for the grooves without increasing the amount of machining, thus, enhancing cooling efficiency when the air flows along the grooves.

  • Patent number: 4951173
    Abstract: This invention provides a creeping discharge type igniter plug, having a center electrode concentrically located within the center bore of the insulator. Near the lower portion of the center electrode is an annular space (6), formed between an outer surface of the center electrode and an inner surface of the semi-conductor ring (4). At the annular space (6), a lateral distance between the outer surface of the center electrode (2) and the inner surface of the semi-conductor ring (4), progressively decreases toward a lower end of the semi-conductor ring (4) thus, making it possible to maintain the least electrical resistance at a creeping discharge path defined from a lower end surface (3a) of the ground electrode (3) to a lower end surface (2a) of the center electrode (2) via a lower end surface (4b) of the semi-conductor ring (4).
