An endoscopic rotary abrader allowing for increased burr size while maintaining the required minimum clearance between the burr and the hood. This is accomplished either by an offset configuration of non-concentric inner and outer tubes, where the inner tube is shifted laterally away from the hood, or by employing an enlarged hood.

A hydraulic antivibration device is provided that is capable of suppressing generation of strange sounds while ensuring a low dynamic spring characteristic upon inputting of relatively small amplitude vibration and a high damping characteristic upon inputting of relatively large amplitude vibration. To that end, upon inputting of relatively large amplitude vibration, displacement-regulating ribs of one of sandwiching members serve to regulate displacement of an elastic partition membrane pinched by the sandwiching members thus obtaining a high damping characteristic. The displacement-regulating ribs consist of three pieces extending radially and rectilinearly, so that the area of openings of the sandwiching members is made wide enough to ensure more a low dynamic spring characteristic. Displacement-regulating protrusions of the elastic partition membrane are disposed to correspond to the displacement-regulating ribs thereby ensuring to suppress the generation of strange sounds.

An ultrasonic endoscope comprising an insertion portion comprising a distal hard portion which has: an endoscopic observation unit; and an ultrasonic observation unit fitted on an outer circumferential section of the endoscopic observation unit, wherein: the ultrasonic observation unit comprises: an ultrasonic transducer array having ultrasonic transducers, and a backing layer cylindrically formed on an inner circumferential surface of the ultrasonic transducer array; and a flexible circuit board on which formed are first terminals each connected to an electrode of a respective one of the ultrasonic transducers, second terminals to which cables are respectively connected, and wiring patterns respectively formed between the first and second terminals, wherein the flexible circuit board has a stepped structure having a large-diameter section on which the first terminals are formed and a small-diameter section on which the second terminals are formed, and an annular support section is formed on an inner circumferential side of the small-diameter section.

A shaft/hub connection between a shaft rotatably driven about an axis of rotation, and a hub disposed on the shaft so as to be non-rotatable relative thereto. The hub has a conical opening and an end face at that end of the hub having the greatest inner diameter. The hub also has at least one relief groove that extends into the hub from the end face thereof. A conical shaft extension on the shaft extends into the conical opening of the hub and is held in the hub via a conical pressure connection.

An apparatus for breast scanning comprises a patient support for a patient to rest in a prone position, the support having an opening with one of her breasts vertically pendent through the opening for scanning; and a laser CT scanner disposed below the support for generating data for reconstruction of images of the breast. The laser CT scanner includes a laser beam for impinging on the breast. The laser beam is orbitable around the breast. The laser CT scanner includes a plurality of detectors positioned in an arc around the breast to simultaneously detect light transmitted through the breast. The measured signal level at the detectors is maintained to an acceptable level while controlling the temperature rise on the breast surface during scanning.

A toothbrush includes a hollow handle which has an outer sleeve made of an elastomeric material which can be expanded or contracted to provide an adjustable diameter grip.

The present inventors have recognized that a pressure gradient or differential in a product distribution line for conveying granular particulate material, such as seed or fertilizer, in an air flow to an agricultural field consistently decreases as air speed (velocity) in the product distribution line decreases until a critical air speed is reached. Below the critical air speed, the particulate material may become susceptible to falling out of the air flow to potentially cause a blockage in the system. Accordingly, pressure sensors arranged in the product distribution line can be monitored for effectively controlling an air source producing the air flow. In one aspect, a diameter of the product distribution line can increase between upstream and downstream locations for monitoring with even greater sensitivity.

In power supply and a semiconductor making apparatus and a semiconductor fabricating method using the same, an abnormality can be detected when an offset occurs in a part constituting a closed-loop system of high-frequency power supply or dc power supply for a semiconductor making apparatus. Power supply for receiving a power value setting signal to set strength of power and a power on/off instruction to set on or off of outputting of the power interrupts the supply of the power even in a state in which a subsequent power on/off instruction is on if a power sense signal according to a value obtained by sensing the power exceeds a predetermined value when the power on/off instruction is off.

A drive unit includes an electric motor including an output shaft including an output gear; a pedal crank shaft extending through a housing, rotatably supported by the housing, and including a driven gear; and a transmission to transmit a torque of the output gear of the electric motor to the driven gear. The transmission includes a decelerator rotatably supported by the housing, and an idle gear rotatably supported by the housing. The decelerator increases the torque of the output shaft of the electric motor, and the increased torque is transmitted to the driven gear via the idle gear.

The present invention relates to a method of manufacturing an optical fiber by carrying out one or more chemical vapor deposition reactions in a substrate tube, with the optical fiber exhibiting a low sensitivity to the hydrogen-induced attenuation losses at a transmission wavelength of 1550 nm. The present invention furthermore relates to an optical fiber comprising a cladding layer and a light-conducting core, which fiber has been obtained by using the present method.
