摘要： A compressor includes a communication hole 42 through which lubrication oil in an oil reservoir 5 is supplied to a back pressure chamber 39 at least through an eccentrically driving bearing 15, and a communication bore 45 or gap through which the lubrication oil in the back pressure chamber 39 is fed into compression spaces, and a constricted resistance member 44 for regulating the oil flow rate is provided on the communication hole 42. The passage resistance can be made larger in comparison with the case where resistance is caused in a small space of a sliding portion of a bearing, and an accurate value of the passage resistance can be preset with the oil flow rate being low, thereby preventing flow of the lubrication oil to the compression operating spaces from increasing in quantity. Thus, there is provided a highly reliable scroll compressor which has a high compression efficiency, consumes power constantly, and has no risk of compression of the lubrication oil in the compression operating spaces.

摘要： An automatic performance device for a keyboard instrument such as piano, organ, cembalo and celesta includes operators such as keys and a pedal provided in a keyboard instrument for producing sounds, a target performance state designation unit for producing target performance information of the keyboard instrument, a real performance state detection circuit for detecting an operation state of the operators and producing a detection output, an actuator such as a solenoid for actuating the operators, and a control circuit for controlling the actuator. The control circuit detects in error between the detection output of the real performance state detection circuit and the target performance information, and generates an operator actuating signal by correcting the target performance information to eliminate the error and supplies the corrected operator actuating signal to the actuator.

摘要： A key actuating device of an automatic playing keyboard instrument has a plurality of key actuator units each of which is provided for each of keys arranged above a key bed of a keyboard instrument, preferably between a balance rail and a front rail, and includes a coil or coils provided above the upper surface of the key bed for producing a magnetic field corresponding to a current supplied from outside and passing therethrough in a direction substantially normal to a rocking direction of the key, a plunger fixedly provided on the lower surface of the key, and a yoke or yokes provided fixedly on the coil or coils and opposing the plunger. A relative area of portions of the yoke and the plunger opposing each other or an interval between these portions is variable in the rocking direction of the key and the plunger is not in contact with the coil or or the yoke at any position of the plunger in the rocking movement of the key. Since there is no mechanical contact between the plunger and the coil or yoke, noise is hardly generated in key actuating operation and damage or wear of the plunger and key can be prevented.

摘要： A solenoid driving apparatus for actuating keys of a player piano is provided in which respective key striking strength data can be applied to respective solenoids of keys, so that musical tones can be reproduced correctly and in which the key striking strength data at the time of musical performance can be compensated for high fidelity reproduction. The solenoid driving apparatus includes a plurality of keys and solenoids provided on each key. When a key is depressed, a first key striking strength data corresponding to key striking strength and a data designating the depressed key are generated. The first key striking strength data is then converted into a second key striking strength data so as to make the latter data in linear proportion to an operating or response speed of the solenoid. In accordance with the second key striking strength data, a solenoid driving data is generated, and is applied to the solenoid corresponding to the key designated by the designating data. The solenoid driving data thus converted from the second key striking strength data causes musical tones to be reproduced as having correct timings and high fidelity.

摘要： In a multiple twister provided with at least a first twisting mechanism and a second twisting mechanism successively arranged, when a yarn supplied from a yarn package held in said multiple twister contacts component elements of the twister, there is a tendency of creating fuzzy fibers projecting from the main body of the yarn. Such fuzzy fibers are laid down against the main body of the supplied yarn by contacting a contacting member disposed at an upstream terminal of a first twisting yarn passage formed in the first twisting mechanism and/or stroked against the main body of the first twisted yarn by contacting a friction surface particularly formed in a yarn guide disposed at a downstream terminal of a second twisting yarn passage formed in the second twisting mechanism so that the laid down fuzzy fibers are twisted into the main body of the yarn.

摘要： A keyboard apparatus capable of enhancing the return capability of hammer assemblies upon key release to improve the capability of repeated key striking and capable of reducing a height size of action units to make the keyboard apparatus compact. The keyboard apparatus includes hammer assemblies each having a butt disposed pivotable about a hammer pivot shaft and a hammer shank extending from the butt. In a non-key-depression state, the hammer shank obliquely extends downward. As viewed from side, a straight line passing though a gravity center position of the hammer assembly and the hammer pivot shaft forms an acute angle less than 45 degrees relative to a horizontal plane in the entirety of a key depression and key release stroke.
