摘要:
A process and apparatus for producing an elongated body changing in elastic modulus longitudinally thereof with use of polymers without resulting in variations in the outside and inside diameters of the body even when the polymers are different in extrusion characteristics or swelling characteristics. The apparatus may include a feeder 1 for extruding a first polymer in a molten state and a feeder 2 for extruding a second polymer, which is different from the first polymer in elastic modulus and similarly in a molten state. The feeders alternately discharge the respective polymers, which are continuously fed to a long-land die 5 along with a lubricant supplied from a lubricant applicator 4. The polymers are formed into the desired shape and cooled in the die 5, and thereafter extruded.

A catheter consists of a torque transmitting portion which has rigidity sufficient for torque transmission and a flexible portion made of a material having a glass transition temperature for giving rigidity before insertion and flexibility after insertion. The torque transmitting portion maintains torque transmitting ability before, during and after insertion. The flexible portion maintains appropriate rigidity before and during insertion, which enables easy insertion, and gains flexibility after insertion by the body heat, which avoids hurting of the vulnerable insertion walls. Further, the torque transmitting portion may have a structure wherein a reinforcement of a coil or a braid of linear metal wires, specifically flat rectangular wires, is attached thereto to afford torque transmitting ability. Catheters having various functions and structures can be easily manufactured by extrusion-molding, or the like.

A first character string is displayed in the vicinity of a first bar code in a state that the first character string can be readily recognized as a character string represented by the first bar code, and all or a part of the second character string is displayed in a state that it cannot be readily recognized as all or a part of a character string represented by the second bar code. When an article on which two or more bar codes and two or more character strings corresponding thereto are displayed is viewed, a character string to be manually entered can be correctly recognized.

A cooling device for use in a low inertia electric motor, in which there are provided a plurality of main passages for cooling air, around the outer circumferential surface of a cylindrical armature which surface is surrounded by magnetic pole pieces with gaps left therebetween. The main passages extend in the axial direction of the armature, so that cooling air is introduced under pressure from the ends of the aforesaid main passages on one side and then discharged from the other ends of the main passages, so as to cool the outer circumferential surface of the armature. At least half of those main passages are of such an arrangement that the cross sectional areas of the main passages are gradually varied from inlets of the main passages towards the outlets thereof, respectively so that a circumferential flow of air through said gaps is created.

Illuminating light emitted from a light source is led via a condenser lens, an optical fiber, a half-silvered mirror, and a condenser lens to a reflector. The reflector reflects the illuminating light to a CCD device through a telecentric optical system which comprises the condenser lens, the half-silvered mirror, and an aperture member. The illuminating light applied to the CCD device is greatly reduced in amount as it passes through a light-transmissive sheet-like body twice. The light-transmissive sheet-like body itself or an edge thereof can be detected with high accuracy even if the light-transmissive sheet-like body has a high transmittance.
摘要:
When a film is rewound, light is applied from light-emitting units to the film, and light that has passed through the film is detected by light-detecting units to detect a plurality of inclined defects in the film based on a change in the intensity of the light transmitted through the film. Slits oriented in the direction of the inclined defects are disposed in front of the light-emitting units and the light-detecting units. Detected signals outputted from the light-detecting units are transmitted to a processing device and processed thereby. The processing device processes the signals by approximating a maximum value array of extremal values of the signals in respective reference lengths of the film, with two functions in zones, and identifying a boundary between the zones as a position where a defect disappears.
