    摘要: A high-frequency knife includes a cylindrical body member, electrically conductive axial member, operating section, and electrical insulating member. At least an outer peripheral surface of the body member has insulating properties. The axial member is inserted in the body member. A distal end portion of the axial member has a knife section. The operating section is provided on a proximal end portion of the axial member, can be actuated by a surgeon to project and retract the axial member with respect to the body member, and can supply electric power to the axial member. The insulating member is provided on the distal end of the axial member in a position at a distance from the distal end of the body member and has at least the longest axis of a cross section of the knife section.

    摘要: An intraline fishing rod includes a hollow rod pipe having an internal surface and an external surface. A plurality of line guide protrusions protrude radially inwardly from the internal surface. Each of the line guide protrusions has front and rear ends, an apex, and front and rear slopes. A water-repellent layer is provided to extend continuously between the line guide protrusions, thereby entirely covering the front and rear ends, the apices and the front and rear slopes of the line guide protrusions and the internal surface of the rod pipe.

    摘要: A pulse generator and a disk sector boundary signal generator are implemented using an optical pattern of alternating light and dark radial lines or segments which are adhered to and rotate in unison with the rotor of a motor and are sensed by an optical sensor. The output of the optical sensor includes error conditions including sensor error, pattern error component, the wow component of the motor and the flutter component of the motor. A first pulse generating means eliminates sensor and pattern error components and the flutter component leaving only the wow component of the sensor output. A second pulse generating means that eliminates the higher frequency error components leaving pattern error components, wow components and flutter components, where the system is designed to generate flutter components with a frequency at least ten times the frequency of the wow component. The first pulses serve as disk sector boundary reference pulses. The second pulses, at a higher frequency, between first pulses contain pattern error pulses corresponding to the sector and the final pulse serves as a sector boundary pulse.
