An electronic musical instrument such as an electronic piano has a musical tone generation structure that closely simulates and reproduces musical tones with nuances of musical expressions with fidelity to acoustic musical instruments such as acoustic pianos. In the casing of the electronic piano, speakers are attached to a speaker attachment plate, which is placed substantially horizontal, such that front sides of the speakers are directed upwards. The sounds radiated from the front sides of the speakers are reflected by a reflector board which is hinged to close or open at a prescribed angle of inclination with respect to a top board, so that reflected sounds are transmitted towards the audience. Enclosures are provided inside of the casing below the speaker attachment plate and contain mufflers having a relatively small thickness therein. Through holes whose openings are directed downwards are formed to penetrate through a bottom plate of the enclosures, wherein the total area of openings of the through holes is larger than the total area of the speakers. Sounds radiated from the backsides of the speakers propagate through the enclosures and are transmitted towards the floor via the through holes, so that reflected sounds are transmitted towards the audience through the air. Further, the electronic piano as a whole vibrates in response to vibrations caused by the speakers. Thus, the electronic piano produces mixed sounds that reproduce acoustic musical tones having the nuances of musical expression of an acoustic piano.

A bipolar transistor using a B-doped Si and Ge alloy for a base in which a Ge content in an emitter-base depletion region and in a base-collector depletion region is greater than a Ge content in a base layer. Diffusion of B from the base layer can be suppressed by making the Ge content in the emitter-base depletion region and in a base-collector depletion region on both sides of the base layer greater than the Ge content in the base layer since the diffusion coefficient of B in the SiGe layer is lowered as the Ge contents increases.

The present invention relates to a sheet conveying apparatus for conveying a sheet in recirculation. The apparatus comprises a feed tray, a feed mechanism, a recirculation conveying mechanism for conveying the sheet fed by the feed mechanism to return it to the feed tray. The recirculation conveying mechanism includes a discharge tray on which the plurality of sheets are temporally discharged and accumulated and a moving mechanism for moving the sheets accumulated on the discharge tray to the feed tray. The apparatus further comprises a feed sensor detecting whether or not any sheets present on the feed tray. The sheets discharged on the discharge tray are moved to the feed tray by the moving mechanism when all sheets on the feed tray are fed and the feed sensor detects none of the sheet.

A method of preparing and cleaning a floating filter medium for a biological cleaning apparatus includes the steps of forming a filter layer by placing in a treating tank a granular floating filter medium having a specific gravity of about 0.3 or less and a particle size of 1 to 15 mm. Wastewater enters the tank and flows through the filter layer. Excess sludge is separated and removed from the filter medium by discharging an amount of water from the treating tank, from below the filtered layer, equivalent to 0.5 to 1.5 times the filling amount of the filter medium in a time period of between 5 to 90 seconds.

An automatic performance apparatus provides a memory capable of storing plural parts of a desirable tune, wherein each part can be independently recorded or reproduced, regardless of recording or reproduction of another part. While performance information of one part is recorded or reproduced after a first detector detects the designation of recording or reproducing of one part so that an automatic performance of one part is played, the automatic performance apparatus can reproduce another performance information of another part after a second detector detects a section end of one part so that another automatic performance of another part is played. This another part is started to be automatically performed at the timing synchronizing with a progress of recording or reproducing the performance information of one part. Thus, the synchronization between one part and another part can be automatically obtained without effort.

摘要:
The present invention provides a high-frequency power amplifying device capable of transmitting output power at high efficiency. For example, a high-frequency power amplifying device has first and second differential amplifiers and a transformer for matching output impedances of the differential amplifiers. Between differential output nodes of the first differential amplifier, an inductor, a switch, and an inductor are coupled in series. When the second differential amplifier is in an operating state and the first differential amplifier is in a non-operating state, the switch is controlled to be on. In this case, due to “off capacitance” in transistors of a differential pair included in the first differential amplifier, impedance on the first differential amplifier side seen from both ends of primary coils becomes a high impedance state (parallel resonance state) and, equivalently, the primary coils do not exert influence on the operation of the second differential amplifier.
