  • Patent number: 11261988
    Abstract: A solenoid valve includes an inner stator and an outer stator that are part of a magnetic circuit. An armature is attracted toward the inner stator when a coil is energized. A spring biases the armature in a direction away from the inner stator. A rod is integrally formed with the armature and integrally reciprocates with the armature. A guide guides reciprocation of the rod. A valve operates by following the rod to open and close a fuel/liquid passage. The spring and sliding portions between the rod and the guide are arranged within a recess portion formed in the inner stator and arranged in parallel to each other while overlapping in the axial direction.

  • Patent number: 9151290
    Abstract: A cylinder body includes a cylinder hole and a discharge flow passage. The cylinder hole receives a plunger and forms a pressurizing chamber in one axial end portion thereof. The discharge flow passage is connected to the pressurizing chamber and is adapted to guide and discharge the pressurized fuel from the pressurizing chamber to an outside of the housing. A connection opening of the discharge flow passage is formed in a hole wall of the cylinder hole. A pressure is applied to a predetermined prestressing subject area in the hole wall of the cylinder hole and a passage wall of the discharge flow passage through autofrettage to generate a residual compression stress in the predetermined prestressing subject area and thereby to form a prestressed area of a final product. The prestressing subject area includes an inner peripheral edge of the connection opening.

  • Patent number: 9091255
    Abstract: A leak recovery groove is formed in a slide clearance between a slidable surface of a cylinder body and a slidable surface of a plunger to recover leaked fuel, which is leaked from a pressurizing chamber. A leak recovery groove direct communication passage is branched from a supply passage, which supplies fuel to the pressurizing chamber, and is connected to the leak recovery groove without passing through the pressurizing chamber to supply the fuel from the supply passage to the leak recovery groove.

  • Publication number: 20130247925
    Abstract: This invention is intended to provide a cigarette paper capable of reducing both a visible sidestream smoke amount and a carbon monoxide amount in a mainstream smoke. The invention provides a cigarette paper having a grammage of 40 to 55 g/m2 and containing calcium carbonate in an amount of 18 g/m2 or more. Where the primary particles of calcium carbonate having a columnar shape or a needle shape are used, the carbon monoxide amount in the mainstream smoke decreases significantly, as compared with the case where the primary particles of calcium carbonate having another shape are used.

  • Publication number: 20070295306
    Abstract: A fuel injection valve includes a valve element, an actuator, a control chamber, and a nozzle. The valve element is provided in a valve chamber. The control chamber is always communicated with the valve chamber. S3>S1>S2 is satisfied in a condition, where the followings are satisfied. S1 is a passage area of a high-pressure seat portion of the valve chamber, which area is a product of a peripheral length of the high-pressure seat portion multiplied by a lift amount of the valve element in a state, where the valve element is disengaged from the high-pressure seat portion. S2 is a passage area of the high-pressure restrictor. S3 is a passage area of the high-pressure fuel passage.

  • Patent number: 7287036
    Abstract: A method and apparatus for automatically accessing a WWW page is provided for realizing a function of automatically jumping to a desired page to automatically download desired data in spite of intervening pages which require a user to enter information, and a function of dealing with a change in configuration of an accessed page. In a web browser, a list structure is created for each displayed window, and all nodes under HTML displayed in a window corresponding to the list structure are copied and stored as node information. Further, when an event occurs with respect to an arbitrary node within a window, an address and event type of the node are recorded in the stored node information corresponding to the node. The record is comprised of a sequence of records of an event occurrence address and event type by using URL and window identifier as keys.
