    摘要： A resectoscope device comprises a sheath body having an elongated hollow sheath to be inserted into a urethra. A handle part has a slider connected to the sheath body and slides in the axial direction. An observing scope is inserted into the sheath through the handle part and sheath body. An electrode is inserted through the sheath, and is removably connected at the rear end to the slider. The electrode has a resecting part that can be projected out of and retreated into a beak opening at the tip of the sheath by the sliding operation in the axial direction of the slider. A stabilizer is provided in the electrode and the scope is able to be inserted therethrough so that a forked part of the electrode may be housed in contact with the inner peripheral surface of the beak and the resecting part may be housed without catching on the beak opening. A spacer which holds the stabilizer constant with respect to the inside surface of the sheath, is provided to set the scope, electrode means and handle without inclining them with respect to the inside surface of the sheath.

    摘要： A magnetostrictive torque sensor comprising a first magnetostrictive film, a second magnetostrictive film, and a third magnetostrictive film formed over the entire circumferential periphery of a surface of a rotating shaft. A first sensor coil, a second sensor coil, and a third sensor coil for sensing changes in impedance are provided for the first, second, and third magnetostrictive films, respectively. Signals according to the changes in impedance outputted from the first through third sensor coils are inputted to a torque calculating unit. The torque calculating unit calculates the torque applied to the rotating shaft on the basis of the output signal from the first sensor coil and the output signal from the second sensor coil. Furthermore, the output signals from the first through third sensor coils are compared, and failures in the first magnetostrictive film or the second magnetostrictive film are detected by a failure detector.

    摘要： The medical apparatus of this invention includes a therapeutic section at least having a blade for treating a living tissue thermally, a heat insulating part for insulating heat conduction from the blade to the main body of the medical apparatus. The therapeutic section and the heat insulating part are preferably provided on a grasping section (for example, a pair of jaws) for grasping the living tissue. It is preferable that the therapeutic section has a shape such that the living tissue and the side surface of the therapeutic section do not contact with each other. It is also preferable that the heat insulating portion has a shape such that the living tissue and the heat insulating portion do not contact with each other.

    摘要： A cylindrical drum is prepared by welding opposite ends of a thin sheet of maraging steel. A first solution treatment is effected on the cylindrical drum, and then the cylindrical drum is severed into a plurality of rings each having a predetermined width. After the rings are rolled, a second solution treatment is effected on the rings which have been rolled, and then the circumferential length of each of the rings is corrected. The rings are aged and nitrided, and then stacked into a laminated ring. The first solution treatment and the second solution treatment are effected using the same heating furnace in the same atmosphere in the same temperature range.

    摘要： Disclosed is a novel electric joining method and apparatus that can overcome the defects associated with the prior art while taking advantage of the technology for the pulse excited sintering process such as spark plasma sintering process or the hot-press joining process. According to the present invention, an electric joining apparatus for joining a plurality of members to be joined at the joining surfaces thereof, comprises: a pair of current-currying electrodes 13, 16 capable of contacting with the members so as to apply electricity to the members; a power supply 17 connected to the pair of energizing electrodes for supplying the energizing electrodes with at least either one of a DC current or a pulsated current; and a pressurizing unit 14 for compressing each of the pair of electrodes against the joining surfaces, wherein the pair of members are sandwiched between the energizing electrodes and applied with at least either one of the DC current or the pulsated current from the power supply under a desired pressure, thus to be joined, without using a die made of graphite.
