摘要： A key actuating system (1) of a keyboard musical instrument is provided which helps quickly push the keys by reducing reaction force with respect to force of pushing the keys during manual operation, and which supports a person having less strength to play the keyboard musical instrument. The key actuating system for a keyboard musical instrument generates a sound when a key (3) is pushed including: a pressure detection sensor (11) detecting a pushing pressure on the key; a status detection sensor (13) detecting a movement status of the key: an actuator (15) actuating the key in a pushing direction of the key; and a control portion (19), when the pressure detection sensor detects the pushing pressure and the status detection sensor detects motion of the key, controls operations of the actuator in order to maintain the detected pressure by the pressure detection sensor at a pressure threshold which is in a range larger than 0 and smaller than a pushing pressure on the key which is necessary for making a sound.

摘要： Three valve assemblies are linked with finger buttons and inserted into a pipe structure of a trumpet for changing the length of air column, and a supporting system assists a player in fingering on the finger buttons; sensors are adhered to the finger buttons so as to supply a detecting signal representative of force exerted on the finger buttons by the player to a controlling unit; when the force exceeds over a threshold, the controlling unit energizes actuators connected to the valve assemblies so as to make the player feel the valve assemblies lightly changed.

摘要： In a laminated construction of a soundboard for use in musical instruments such as the piano, the use of a core having larger shearing elastic modulus and/or smaller shearing loss tangent than that of the fore and rear plates assures small shearing loss in the treble range, and greatly improves the total tonal balance over the entire tonal range.

摘要： A lower core is formed on the surface of a wafer and then a protection film made of substance that has a lower ion milling rate than that of the lower core is formed so as to coat the lower core. Then, the protection film is ground to expose the lower core under the film, and the surface of the protection film and that of the lower core are finished smooth and level. Then, ion beams are radiated to simultaneously mill both the protection film and the lower core and thereby form a recess above the lower core. Next, a gap layer is formed on the surfaces of both the protection film and the lower core. Then, an upper core is formed in the recess above the lower core with a gap layer between them. Accordingly, only the part in which the pole of the upper core and the pole of the lower core face each other in parallel is magnetically effective. This ensures a constant track width even in mass production provided that only the lower core is formed strictly in accordance with the design. In this case, formation of a lower core in accordance with the design is possible. Further, since the surplus part of the upper core does not actually provide a read/write function of a head, cross-talk is seldom generated between adjacent tracks. Conducting milling before forming an upper core elminates magnetic shortcircuiting between the upper and lower cores.
摘要翻译：在晶片的表面上形成下芯，然后形成具有比下芯的离子研磨速度低的物质制成的保护膜，以涂覆下芯。然后，保护膜被研磨以暴露膜下的下芯，保护膜的表面和下芯的表面光滑平整。然后，照射离子束同时研磨保护膜和下芯，从而在下芯上形成凹陷。接下来，在保护膜和下芯的表面上形成间隙层。然后，在下部芯部上方的凹部中形成上部芯部，在它们之间具有间隙层。因此，只有上芯的极和下芯的磁极平行的部分才是磁性有效的。即使在大规模生产中也能确保轨道宽度恒定，只要根据设计严格地形成下芯。在这种情况下，可以根据设计形成下芯。此外，由于上层的剩余部分实际上不提供头的读/写功能，所以在相邻轨道之间很少产生串扰。在形成上芯之前的导电铣削可以使上，下芯之间的磁短路导致电磁场短路。

摘要： On a substrate, a lower pole is formed being embedded in a protective film on which a gap layer is formed. On this gap layer, a first upper pole is formed facing the lower pole. A protective film is formed coplanar to the upper surface of the first upper pole. On this protective film, a coil made of a plurality of coil layers is formed being embedded in an insulating film. On the insulating film, an upper core layer is formed whose tip portion constitutes a second upper pole stacked upon the first upper pole and magnetically coupled thereto. The first upper pole formed before the coil is formed and the second upper pole formed after the coil is formed, constitute an upper pole.
