Abstract: In a dry cutting and grooving apparatus for pavement in which blades for cutting or grooving the pavement are covered by a housing which leaves the lower ends of the blades exposed, and in which chips and cutting powder generated at the time of cutting and grooving operation by the blades are collected by a suction means connected to the housing, air is forcibly supplied to the housing and the dust stored within the housing is quickly scavenged by the air flow toward the suction end. Further, by providing an air supply passage within the main shaft of the blades and discharging the air from the surface and the outer periphery of the blades, the dust within the housing is scavenged in the same manner while the tips of the blades can be cooled by the discharged air.

Abstract: A multi-color small amount painting system of the present invention stores small unit amounts of paint having a variety of paint colors and may selectively feed desired color paint to a painter of a painting robot or the like. The painting system stores the paint having a large number of paint colors in a stock unit in the form of paint cartridges. The paint cartridge of the paint color selected is picked up from the stock unit and carried by a carrier and is loaded on the painting robot or an automatic painting device. Subsequently, the paint within the paint cartridge loaded is fed to the painter of the painting robot or the automatic painting device by a paint feeding mechanism. In addition, the system ensure an advantage that the painting system is high in efficiency of painting work including the exchange of colors and is small in size as a whole.

Abstract: In executing a music performance on the basis of supplied performance data, a feeling of swing can be imparted to the performance by delaying tone-generation start time of a tone, based on the performance data, at each predetermined beat such as upbeat. In this case, if an original tone-generation end time of the tone to be delayed is ahead of tone-generation start time of a next tone, control is executed to automatically change a duration of the tone in such a manner that actual tone-generation end time of the delayed note comes ahead of the tone-generation start time of the next tone. In this manner, the delay control can be properly executed on staccato performance data without losing characteristics of staccato.

Abstract: There is provided a unit capable of simultaneously producing nitrogen of ra high purity and oxygen of ultra high purity from air as a feed material. Feed air is introduced into to the bottom 15 of a first rectification column 6. Liquid nitrogen of ultra high purity is recovered from between the upper rectifying part 12 and middle rectifying part 13, and liquid air free of high boiling point components is recovered from between the middle rectifying part 13 and lower rectifying part 14.

Abstract: An automatic performance, such as an automatic arpeggio performance or a short-phrase sequence performance, is executed on the the basis of manual performance note data corresponding to key depression on a keyboard, and automatic performance note data are obtained from the automatic performance. The manual performance note data and automatic performance note data are output to an external device after both of the note data are imparted different MIDI channel messages, i.e., channel identification data. The manual performance note data and automatic performance note data can be used properly because they can be accurately distinguished from each other by the different channel identification data. For example, it is possible to avoid the inconvenience that a further automatic performance is executed on the basis of the automatic performance note data.

Abstract: A keyhole-shutter structure includes a cylindrical protector block. An upper portion of the protector block includes an approximately square housing portion. A shutter plate is fitted in the housing portion. A cap is placed on the protector block. The bottom of the housing portion has right and left receiving planes for receiving the shutter plate, and a recess formed between the right and left receiving planes in such a manner as to be curved downwardly. Since a recess is provided between right and left receiving planes for receiving a shutter plate, even if the shutter plate is somewhat deformed, the deformed portion interferes to a lesser extent with the recess. Accordingly, a key can be easily inserted into a keyhole even if the shutter plate is somewhat deformed.

Abstract: Ultra-high purity nitrogen is generated by removing, from feed air, carbon dioxide, moisture and catalyst poisons of an oxidation catalyst contained therein by a decarbonating drier (4). The feed air is then introduced into a low-pressure rectification column (6), where it is roughly rectified to further remove the carbon dioxide, moisture and catalyst poison. Then raw nitrogen gas obtained in the low-pressure rectification column (6) is introduced into an oxidation column (8) so that carbon monoxide in the raw nitrogen gas is converted to carbon dioxide and hydrogen also contained therein to water. Thereafter the raw nitrogen gas is introduced into an adsorption column (10) so that carbon dioxide and water are removed by adsorption to provide feed raw nitrogen gas, which is fed into an intermediate-pressure rectification column (11), where it is rectified.
