Abstract: An air cleaner unit of the present invention includes a removable cleaner case having defined therein an outflow port, located below the filter element, for discharging an air, introduced into the cleaner case, towards the combustion engine and including a case body opening downwardly and a bottom plate closing the opening of the case body, and a filter element replaceably accommodated within the cleaner case for substantially purifying the air introduced into the cleaner case through an air intake port. A pedestal is carried by the combustion engine and has an outer peripheral surface, which is substantially in flush with an outer peripheral surface of the filter element within the cleaner case. This filter element within the cleaner case is removably mounted on the pedestal. The bottom plate has a mounting hole defined therein and encircling the outer peripheral surface of the pedestal.

Abstract: A liquid-cooled, vertical shaft type combustion engine is provided with a duct utilizing a stream of cooling air induced by a cooling fan to cool various parts of the combustion engine. The combustion engine includes an engine body, a crankshaft accommodated in the engine body so as to extend in a vertical direction, at least one engine cylinder head disposed at a front portion of the engine body, a radiator mounted above the engine body for circulating an engine coolant, a duct positioned below the radiator, and a cooling fan operatively accommodated within the duct. The duct has at least a front discharge opening and side discharge ports defined in a peripheral wall for discharging a stream of cooling air induced by the cooling fan, in a direction forwardly of the engine body and in a direction slantwise forwardly of the engine body.

Abstract: An information processing system having a first information processing apparatus and a second information processing apparatus connected via a network. The first information processing apparatus comprises first storing means storing music material data constituting music data for playing back music; second storing means storing music composition data describing, for each item of the music material data, playback conditions for music to be played back using the music data; and transmitting means transmitting the music material data or the music composition data to the second information processing apparatus.

Abstract: An air cleaner unit (7) of the present invention includes a removable cleaner case (70) having defined therein an outflow port (101), located below the filter element, for discharging an air, introduced into the cleaner case (70), towards the combustion engine and including a case body (71) opening downwardly and a bottom plate (73) closing the opening of the case body (71), and a filter element (72) replaceably accommodated within the cleaner case (70) for substantially purifying the air introduced into the cleaner case through an air intake port (74). A pedestal (60) is carried by the combustion engine and has an outer peripheral surface, which is substantially in flush with an outer peripheral surface of the filter element within the cleaner case (70). This filter element (72) within the cleaner case (70) is removably mounted on the pedestal (70). The bottom plate (73) has a mounting hole (73c) defined therein and encircling the outer peripheral surface of the pedestal (60).

Abstract: There is provided a liquid-cooled, vertical shaft type combustion engine which is compact in size and inexpensive in cost and which is provided with a duct capable of effectively utilizing a stream of cooling air induced by a cooling fan to cool various parts of the combustion engine with a high cooling performance. The liquid-cooled, vertical shaft type combustion engine includes an engine body (E), a crankshaft (2) accommodated in the engine body (E) so as to extend in a vertical direction, at least one engine cylinder head (31) disposed at a front portion of the engine body (E), a radiator (4) mounted above the engine body (E) for circulating an engine coolant, a duct (5) positioned below the radiator (4), and a cooling fan (6) operatively accommodated within the duct (5).

Abstract: A multiple cylinder engine controls an air/fuel ratio accurately by improved detection of the fluctuations in a vacuum due to a change in the openings of throttle valves. The multiple cylinder engine includes a plurality of intake passages that independently feed intake air to cylinders; fuel injectors; throttle valves; a pressure sensor; and a fuel controller that controls fuel injection of each cylinder using the detected pressure. The multiple cylinder engine may further include a vacuum inlet passage having an inlet port opened into intake passages that introduces the pressure of the intake passages into the pressure sensor. The vacuum inlet passage preferably includes a throttle portion having a passage area of no more than one ninth that of the inlet port.

Abstract: A multiple cylinder engine controls an air/fuel ratio accurately by improved detection of the fluctuations in a vacuum due to a change in the openings of throttle valves. The multiple cylinder engine comprises: a plurality of intake passages 11a and 11b for feeding intake air to cylinders 2 and 3 independently of each other; fuel injectors 6 and 7 and throttle valves 4c provided for the intake passages; a pressure sensor C for detecting the pressure of one of the intake passages 11a and 11b; and fuel control means 20 for controlling the injection quality of the fuel injectors 6, 7 of each cylinder by using the detected pressure. The multiple cylinder engine may further comprise a vacuum inlet passage 18 having a inlet port 18a opened into intake passages 11a or 11b that introduces the pressure of the intake passages 11a or 11b into the pressure sensor C. The vacuum inlet passage 18 includes a throttle portion 18b preferably having a passage area of no more than one ninth that of the inlet port 18a.

Abstract: With music data made up of four instrument/vocal parts of, e.g., a piano, base, drums, and vocals, project data handled by a management center is configured of tracks with each part existing independently. Tracks 1 through 4 each have independent copyright information, which is to say that even in the event that the tracks 1 through 4 are each created by different creators, copyright information is recorded to each of the tracks 1 through 4, and even in the event that a track for a new part is added to the project data for example, thereby generating different project data, the copyright information on each track is not deleted. Thus, music data made up of multiple tracks having copyright information on each track can be distributed.
