Abstract: A magnetic component includes a core, at least one spacer and at least two coils. The core includes an inner leg and at least two outer legs. The at least two coils and the at least one spacer are stacked with each other and directly sleeved on the inner leg. Each of the at least two coils is formed by winding a wire covered by at least three misaligned layers of insulating tape.

Abstract: A switchable multi-mode dental handpiece structure and method, includes: a root canal mirror assembly with an image sensor for capturing external images; a flexible hose with one end connected to the image sensor; a rigid tube connected to the other end of the flexible hose; a root canal operation assembly, includes: a working head; a driving device connected to the working head for driving the working head, the driving device being operable to follow the rotational direction of a steering wheel; a connecting rod linking the steering wheel; a mode switching push handle, connected to the rigid tube and the connecting rod, for switching between various handpiece modes, such as a linkage mode, an individual operation mode, a storage mode, and an intraoral operation mode.

Abstract: A nanometal dispersion and a method for preparing a nanometal dispersion are provided. The method comprises the following steps: providing a first solution containing a metal ion; providing a second solution containing inulin; mixing the first solution and the second solution to provide a third solution; and providing energy to the third solution to conduct a reduction-oxidation reaction to form a nanometal therein. The produced nanometal dispersion comprises inulin and a nanometal with multimorphology.

Abstract: The present invention relates to a flexible-tubed structure of an endoscope comprising a plurality of cylindrical units, a first wire, a second wire, a first flexible unit, and a second flexible unit. The wires respectively pass through the cylindrical units. The flexible units are continuously disposed at the recesses of the cylindrical units. The cylindrical units are used to form a tubular unit by the flexible units. The tubular unit is bent by the tension of the first wire or the second wire to control the turning-direction of the camera apparatus.

Abstract: The present invention is a hand-held endoscopic device with a rotation control, having a mainframe, a flexible cable, and a tube module. Moreover, the tube module includes a probe, a image capturing element and a sheath; besides, the second front end of the sheath has an opening which includes a mirror to allow the user to rotate the opening of the sheath in accordance with the situation, so that the image capturing element can reflect the light through the mirror to capture the image from different perspectives.

Abstract: The present invention provides an endoscope with function of acoustic wave detection and voiceprint comparison. The endoscope includes a flexible tube, a hand-held host and a sound receiving element. The hand-held host includes an analog-to-digital converter, a storage unit and a digital signal processor. The sound receiving element is disposed at the control module. The sound receiving element is used to convert surrounding acoustic waves to acoustic analog signals, and transmits the acoustic analog signals to the analog-to-digital converter of the hand-held host via the signal wires. The analog-to-digital converter converts the acoustic analog signals to digital signals, and transmits the digital signals to the digital signal processor for comparing the digital signals with the voiceprint data stored in the storage unit. The digital signal processor makes the comparison result shown at the display of the hand-held host.

Abstract: An endoscope with adjustable viewing angle has a viewing angle adjusting mechanism mounted on a handheld body and a control module mounted inside the handheld body. The viewing angle adjusting mechanism has a cable seat pivotally mounted on the handheld body, an adjustable knob mounted on the cable seat, a flexible tube, a hollow flexible cable joined with one end of a flexible tube, and two pull strings between the other end of the flexible tube and the adjusting knob. Given that, while the cable seat is rotated, the image acquisition module on one end of the flexible cable can be controlled to rotate synchronously. The relative pulling and releasing movement of the two pull strings driven by turning the adjusting knob makes the flexible tube bend correspondingly so as to further adjust the viewing angle of the image acquisition module.
