  • Patent number: 8863722
    Abstract: A machined shape of a bore is based on the deformation amount of a data-acquisition bore after fastening of cylinder head. A cross section of an approximate shape is set to be an approximately-true circle shape, and a diameter of the approximately-true circle shape is changed along a central axial direction in accordance with the deformation amount of the data-acquisition bore, to determine the approximate shape. The approximate shape has a cross section having the approximately-true circle shape and has a simple shape which is symmetrical about the central axis. Since the machined shape of the bore is the shape obtained by reversing a phase of a recess and a projection of the approximate shape about a predetermined cylindrical shape, the machined shape has a cross section having the approximately-true circle shape and has a simple shape which is symmetrical about the central axis.

  • Patent number: 8690025
    Abstract: A dispensing container according to the invention includes a container body having a rod-like shape. The dispensing container is therefore compact and the user can hold the dispensing container as if the user holds a pen and use the thumb, the index finger, and any other finger to apply pressure to the dispensing container so as to dispense a drug solution. A heat insulating grip is attached to the outer circumferential surface of the container body, whereby heat originating from the body temperature of a finger of the user will not be transferred to the drug solution or volatilize it. No excessive dispensing that is not intended by the user will therefore occur. Since the container body is thin and hence unlikely crashed, the user can make adjustment of the pressure applied by the thumb, the index finger, and any other finger to readily extract a single droplet.

  • Patent number: 8622932
    Abstract: An object of the present invention is to provide a guidewire having high safety and improved flexibility and rotation followability. This guidewire has an inner coil that surrounds a distal side portion of a core shaft, and an outer coil that surrounds the inner coil and the distal side portion of the core shaft. A front end of the outer coil and a front end of the inner coil are joined to a tip of the core shaft by a tip plug. Further, the guidewire has a coil joint that joins only the outer coil and the inner coil to each other. With this configuration, the flexibility of the inner coil is maintained. Moreover, rotation of a proximal side of the guidewire is transmitted to the inner coil not only from the core shaft but also from the outer coil. This leads to improvement in rotation followability.

  • Patent number: 8608670
    Abstract: An object of the present invention is to provide a guidewire having high safety and improved flexibility and rotation followability, and capable of directing a catheter with ease. A guidewire of the present invention has an inner coil that surrounds a distal side portion of a core shaft, and an outer coil that surrounds the inner coil and the distal side portion of the core shaft. The core shaft has a second flat part in flattened shape in substantially contact with an inner peripheral surface of the inner coil. With this configuration, the distal side portion of the guidewire is protected by a double coil structure, while having high torsional stiffness. This leads to improvement in safety and rotation followability, while allowing a catheter to be directed with ease.
