摘要： A lever 1 pivots within a certain stroke range by a player's depression of the lever 1. A coil spring 4 is displaceable within the entire stroke range of the lever 1 to produce a reaction force having a characteristic that the reaction force increases with an increase in the displacement. A dome-shaped rubber member 5 starts being displaced at some point in the stroke of the lever 1 to produce a reaction force having a characteristic that the rate of change in reaction force with respect to the displacement decreases in an area placed in the displacement. The characteristic is obtained by the dome-shaped rubber member 5 coming into contact with the lever 1 at some point in the stroke of the lever 1 to start being displaced by further depression of the lever 1 to buckle at some point in the displacement of the dome-shaped rubber member 5.

摘要： A keyboard apparatus of this electronic musical instrument is provided with touch curves TW1 through TWp, TB1 through TBq each defining a velocity value Vc varying with a key-depression velocity Kv (TD). Each of keys K1 through Kn of a keyboard 14k is associated with one of the touch curves TW1 through Twp, TB1 through TBq by touch selecting tables SW, SB in accordance with an equalization rule and a weighting rule. Upon a key-depression, in accordance with the velocity curve TWr, TBs selected on the basis of an actual depressed key position Ki (M2), an actual key-depression velocity Kva is converted into a velocity Vca for controlling emission of a tone (M3).

摘要： An electronic keyboard instrument is assembled on a frame member. A keyboard has a plurality of keys pivotably supported by the frame member. A lower case is formed integrally with or separately from the frame member under the keyboard. An electroacoustic transducer is accommodated in a space between the keyboard and a bottom plate of the lower case, and outputs an acoustic wave. The acoustic wave outputted from the electroacoustic transducer is radiated outwardly through sound passages configured as gaps in the frame member and gaps between the plurality of the keys.

摘要： A keyboard apparatus includes: keys composed of white keys and black keys supported pivotably on a key mounting part of a frame; mass members pivotably supported on a mass member mounting part and driven by mass member driving parts provided underside of the keys; and a mass member lower limit stopper and a mass member upper limit stopper restricting a pivot range of the mass members. Each of the mass members includes a mass concentration part. The mass concentration part extends more outward in a key longitudinal direction than a position where the mass member upper limit stopper on the frame is disposed, and an upper face of the mass concentration part at its highest lifted position is substantially flush with an upper face of a rear end portion of the white key main body.

摘要： A key structure which is capable of giving a woody appearance to the key, and increasing the freedom of mounting at least one functional part formed as a separate part from the key structure, while maintaining excellent machinability. An upper plate has an increased width part corresponding to an end of a white key toward a player. In the key structure, a wood part is secured to the lower surface of at least the increased width part of the upper plate, and has an increased width part having substantially the same width as the increased width part of the upper plate. The key structure is mountable in a keyboard apparatus, for functioning as a white key pivotally moved by key-depressing operation. A recess is formed in a part of the wood part including the increased width part, which opens downward and has a width (W0) not less than 50% and not more than 80% of the width (B0) of the increased width part of the wood part.

摘要： In a control system for an internal combustion engine having a plurality of cylinders and mounted on a vehicle, in which the engine operation is switched based on the throttle opening between a full-cylinder operation in which all of the cylinders are operative and a cut-off cylinder operation in which some of the cylinders are inoperative, and a running control including at least a cruise control in which the vehicle runs at a desired vehicle velocity is conducted, the engine operation is switched to the full-cylinder operation when it is determined that deceleration is required in the running control, so as to increase pumping loss (engine loss). With this, it becomes possible to generate the deceleration sufficiently as desired, when, for example, the vehicle descends a downhill.

摘要： In an electronic keyboard instrument, each key moves from an initial position to a full stroke position via first, second, and third positions sequentially. A velocity detector detects a first key velocity of the key when the key moves from the first position to the second position, and detects a second key velocity of the key when the key further moves from the second position to the third position. A predictor obtains a predicted key-on time and a predicted key velocity based on the first key velocity, provided that the first key velocity is greater than a predetermined threshold velocity. A tone generator generates a musical sound signal based on the first key velocity and the predicted key velocity if the second key velocity is not detected before the predicted key-on time.
