Abstract: An endoscope is provided with a bending tube including sequentially connected plural bending pieces constituting a bending section which is provided in a slim and elongated insertion portion and which is brought into a bending operation by remote control, a distal end section which is provided in the front end side of this bending tube and which constitutes the front end side of the insertion portion, a flexible tube section which is provided in the base end side of the bending tube and which constitutes the rear end side of the insertion portion, and a covering member which is disposed to cover the bending tube and which has elasticity in order that both end portions of the covering member are fixed to the distal end section or the flexible tube section by being fastened radially inward, wherein the relationship represented by 0.3D<d<1.0D is established between a thickness d of the covering member fixed by fastening and the thickness D of the covering member before being fixed by fastening.

Abstract: This invention uses a two-part reaction type adhesive obtained by mixing a base compound containing at least one of a bisphenol A type epoxy resin and bisphenol F type epoxy resin and 5 to 15 wt % of a fine acrylic rubber powder having an average particle size of 300 nm or less, and a curing agent containing dimer acid, diethylenetriamine, and a diethylenetriamine monomer as main components.

Abstract: A sealing resin composition for sealing wiring portions of medical instrument, which comprises a thermosetting epoxy resin composition containing a fullerene compound.

Abstract: An endoscope comprising an operation part, and an intracavital insertion part attached to the operation part and formed of a flexible tube, wherein the yarn employed for the component member of the flexible tube and the yarn employed for fixing the internal member contained in the flexible tube respectively contain aramid fiber.

Abstract: A tricycle with an electric motor in which two rear wheels 4 and 4 are driven by not only an electric motor 5, but also pedals 6 with manpower. A rotational force of the pedals 6 is transmitted to drive shaft 9 via first bevel gears 8a and 8b and then transmitted to a one-way clutch 7 via second bevel gears 10a and 10b from the drive shaft 9. The output of the one-way clutch 7 is then transmitted to the two rear wheels 4 and 4. The electric current to the electric motor is a pulse current and its pulse width is controlled to be shorted in relation to a braking operation.

Abstract: A medical instrument comprises an operating section and an insertion section connected to the operating section and adapted to be inserted into a living body, the insertion section including a tubular member formed of a liquid crystal polymer. The tubular member constituting the insertion section of the medical instrument or a channel tube disposed in the insertion section is formed thin-walled by using the liquid crystal polymer.
