摘要： A closed compressor includes a closed vessel having an oil sump in which lubricating oil which is incompatible with a refrigerant is accommodated. A compression mechanism, to which a rotary shaft is connected, is accommodated in the closed vessel. An electric motor is also accommodated in the closed vessel for rotating the rotary shaft to drive the compression mechanism. An oil supply pipe is secured to a lower end of the rotary shaft to draw the lubricating oil contained in the oil sump to the compression mechanism. A generally cylindrical partition wall is formed in the oil sump so as to encircle the oil supply pipe and has a plurality of holes to allow the lubricating oil to pass therethrough. The generally cylindrical partition wall may be replaced with a partition wall that laterally partitions the oil sump into two portions. It is preferred that the plurality of holes includes at least vertically spaced first and second rows of holes with the first row being positioned above the second row. Each hole of the first row has an area greater than the holes of the second row.

摘要： A lever is supported by a lever supporting portion. The lever is urged by a first spring and a second spring. The urging force of the first spring varies over the entire operational range of the lever. The second spring and a third spring are provided serially through a movable supporting member. The displacement of the movable supporting member is restricted by a fixed supporting member. If the urging force of the second spring exceeds the urging force of the third spring, the restriction on the displacement of the movable supporting member is removed. Therefore, the present configuration provides a player with feeling similar to that the player perceives when he manipulates a damper pedal of an acoustic piano.

摘要： A self-calibrating key sensor system is constituted by an optical modulator, optical position transducers, a data accumulator and a data analyzer, and the optical modulator has a gray scale section to produce a key position signal varied together with the keystroke and an absolute data section to produce a calibration signal representative of a strictly adjusted distance between transparent areas of the absolute data section; the data accumulator accumulates discrete values of the calibration signal and discrete values of the key position signal together with the sampling time, and the data analyzer determines the gradient of the key position signal on the basis of peaks of the calibration signal produced at both ends of the strictly adjusted distance so as to estimate the true distance between the rest and end positions.

摘要： A key structure includes a top plate which is formed by laminating a half-transparent resin surface layer member on a resin bottom side member using two-color injection molding, and the top plate is secured on a wooden key base. A plurality of concave grooves and protrusions, and a plurality of protrusion and troughs are respectively formed together in straight lines in the long direction of the key structure on a rear face of the surface layer member and a top face of the rear side member. Outside light is reflected from the top ends of the protrusion and the troughs, whereby a faint and natural vertically-striped pattern, which corresponds to a concave-convex part formed by the concave grooves and the protrusions, is perceived as resembling an edge grain of ivory.

摘要： A sealed compressor has a sealed casing in which a motor section and a compression section are both accommodated, and also has a pipe connector including at least one sleeve. The sleeve has a first end and a second end opposite to each other. The first end is inserted into a sleeve insertion hole defined in the compression section to allow a refrigerant to flow therethrough, while the second end is hermetically brazed to a copper pipe disposed outside the sealed casing. The sleeve is formed by deep-drawing a copper-plated steel plate into a generally cylindrical shape.

摘要： A hermetically sealed rotary compressor includes a generally cylindrical sealed vessel having an oil reservoir defined therein for accommodating a quantity of lubricating oil, a drive unit within the sealed vessel, and a compressor mechanism within the sealed vessel. The compressor mechanism includes a cylinder having a compression compartment defined therein and also having upper and lower openings, an eccentric cam provided on a crankshaft for rotation together therewith, and a ring-shaped piston mounted on the crankshaft while encircling the eccentric cam and capable of undergoing a planetary motion in contact with the eccentric cam during rotation of the eccentric cam. The cylinder has a refrigerant intake port defined therein in communication with the compression compartment. A radial vane is slidably accommodated in the cylinder for reciprocating movement in a direction radially of the cylinder and having a radial inner end held in sliding contact with an outer peripheral surface of the ring-shaped piston. An oil supply tube having first and second open ends opposite to each other is disposed with the first open end communicated with the oil reservoir and the second open end communicated with the compression compartment while a generally intermediate portion of the oil supply tube extends outside the sealed vessel.
