  • Patent number: 9109490
    Abstract: An electric heating catalyst (EHC) in which a short circuit between a heat generation element and a case in EHC is suppressed. The EHC includes a heat generation element (catalyst carrier) electrically energized to generate heat; a case receiving the heat generation element; an insulating support member between the heat generation element and the case; a tubular inner pipe inserted into the insulating support member and located between the heat generation element and the case. The inner pipe has an end protruding into an exhaust gas from the insulating support member's end face, and the inner pipe has an electrically insulating layer formed on an entire surface, or the inner pipe is formed of an electrically insulating material; and an inner pipe heater supplied with electricity through a path different from a path through which electricity is supplied to the heat generation element, thereby heating the inner pipe's protrusion portion.

    Abstract: An expandable writing instrument has a writing end body section and a rear body section mounted to the writing end body section for relative axial and non-rotational movement between an extended position with the rear body section spaced away from the writing end body section, and a retracted position with the rear body section closer to the writing end body section. A spring in the writing end body section biases the cartridge upwardly. A helix cylinder is mounted for rotation and axial movement in the rear body section with a peg of the rear body section sliding in a track of the helix cylinder. The track is a closed loop with left and right hand helixes so that axial movement of the rear body section causes rotation of the helix cylinder continuously in one rotational direction. A shuttle receives a cartridge body and is mounted for axial movement in the helix cylinder. A shuttle cam on the shuttle is mounted for axial non-rotational movement to the writing end body section.

  • Patent number: 7931415
    Abstract: Upon depressing a knock rod in a state of writing of FIG. 8A, a cam protuberance 3b of a rotor turns rightward to assume a position shown in FIG. 8B. Upon removing a finger, the cam protuberance 3b turns sliding on a tilted surface, arrives at a position shown in FIG. 8C through a first vertical motion (distance d) and, further, arrives at a position shown in FIG. 8D through a second vertical motion (distance e). Here, a tilted surface of cam protuberance 3b comes in collision with a tilted surface of an inner cylinder cam 2b twice, and shocks are transmitted to a refill 7. By forming a step between the front half and the rear half of the tilted surface of the inner cylinder cam 2b, however, a distance of vertical motion of the cam protuberance 3b each time is shortened to decrease the shock of collision imparted to the refill each time.

  • Patent number: 6280110
    Abstract: A pressing device for a pen having a spring, a center stick engaging the spring and a nib part. The pressing device comprises a penholder having a guide slot, a movable tube having an outwardly projecting engaging piece that extends through the guide slot, a bounce device, a press or push cap, and a clipping part. The clipping part has a pen clip provided with a clamping piece that engages the engaging piece when the nib part is extended outwardly from the penholder in a writting position. When the pen is being attached to an article such as a pocket, the clamping piece will touch the article such that the pen clip is urged to move outward. As a result, the clamping piece will disengage the engaging piece. The engaging piece will move upward along the guide slot causing the spring to be stretched pressing the center stick upward such that the nib part will be received in the penholder.

  • Patent number: 5915866
    Abstract: A clicking-type ball point pen has a so-called double-clicking mechanism in which a clicking rod is projected by depression and is retracted by further depression. At least one undercut is formed in the inner surface of a rear barrel cylinder or a component fixed to the rear barrel cylinder to prevent a rotor and the clicking rod from being removed forward from the barrel cylinder. The barrel cylinder incorporates a writing element having a large diameter. A point assembly holder at the distal end of the barrel cylinder has a straight portion, which constantly urges a writing ball forward with a load of 1 g to 80 g, and an elastic portion having spring properties integrally, or in a contact state if the straight portion and the elastic portion are separate components. An ink present from the interior of the point assembly to a follower is defoamed such that a gas, e.g., air, water vapor, or a gas formed of a vaporized organic solvent, which is larger than 0.524 mm.sup.
