An implantable middle ear hearing device having a tubular vibration transducer to drive a round window is designed to input sound to a round window opposite an oval window in an inner ear. The tubular vibration transducer has a unique structure that does not attenuate the magnitude of a signal, particularly, in a high frequency band. Sound delivery effect is much higher than those of conventional schemes. It is also possible to minimize difficulties associated with and problems resulting from the operation, which the conventional methods would have. Further, the transducer can have a relatively less compact than ossicle contact type transducers, and thus be easily fabricated. The hearing device can be applied to a sensorineural hearing loss patient with the ossicle damaged. Moreover, since sound is directly transmitted without through the ear drum and the ossicle, high efficiency sound delivery is achievable and hearing loss compensation are easy.

A toothbrush assembly with a sound generating function for providing excitement and entertainment to a user and for encouraging a young child to brush his or her teeth is provided. The toothbrush assembly has a contact-type switch and a sound generator. The contact-type switch has a swingable contact and generates a pulse when a power switch of the assembly is instantaneously closed for every swing of the swingable contact according to the tooth-brushing movement of a user. The sound generator has a counter for counting pulses from the contact-type switch and a sound recording and play back unit for generating a voice message or musical tone when the sum of the pulses counted by the counter reaches a predetermined value. The sound recording and play back unit of the sound generator outputs different voice messages or musical tones according to different predetermined values reached by the sum of the pulses counted by the counter.

The invention discloses a method and device for online detection of the size of a city rail train wheel set. A system is mainly comprises two 2D laser displacement sensors arranged along a train rail in a mirror symmetric mode, and two laser bijection switches arranged on the two sides of the same rail in a certain geometrical relation. The 2D laser displacement sensors detect and obtain tread contour lines, and the two laser bijection switches detect the wheel passing speed. The rim height and the rim thickness are worked out by extracting the tread contour lines of wheels passing through a detection system according to the geometrical relation. The coordinates of the lowest rim points of the detected tread contour lines of the wheels at different moments are extracted, the coordinates at the different moments are restored to coordinate values at the same moment on the condition that the speed is given, so that the circle where the top points of the rims of the wheels are located is fitted out, the two times of the height of the rims is subtracted from the diameter of the circle of the top points of the rims, and thus the diameters of the wheels are obtained. The method and device for online detection of the size of the city rail train wheel set are low in cost, simple in operation and high in non-contact type measurement precision.

An object of the present invention is to provide a semiconductor device such as a display device, ID tag, sensor or the like at low cost by using a bottom contact type organic TFT as a switching element. In the present invention, the semiconductor layer of the bottom contact type organic TFT is formed of a polycrystalline material, and the taper width of each of the source and drain electrodes of the TFT in the direction of the channel length is smaller than the average particle size of semiconductor crystals grown on the source and drain electrodes. Alternatively, the side on the channel side of each of the source and drain electrodes of the bottom contact type organic TFT is formed so as to be convex upward with respect to the substrate surface. Alternatively, an organic compound layer different from the semiconductor layer of the bottom contact type organic TFT is made present between each of the source and drain electrodes of the bottom contact type organic TFT and said semiconductor layer, in a thickness of not more than 10 Å and not less than 1 Å.

The projections being formed in at least two directions with a substantially periodical pitch that is shorter than any wavelength of visible light. The touch panel can also include a lower transparent electrode and an upper transparent electrode formed over the inner surfaces of the lower substrate and the upper substrate having the pluralities of projections, respectively. The cross-sectional area of each of the projections parallel to the outer surface of the lower substrate is configured to decrease continuously from bottom to top of the projection. The same applies to the combination of each of the projections, the bottom and a top thereof, and the upper substrate. Accordingly, this structure reduces the light reflection and diffraction at the boundary between an air space and the transparent electrode, thereby providing a resistive contact-type touch panel or a electrostatic capacitive coupling-type touch panel having high light transmittance.
