    • A drum pad has a knitted material that is strechable and has a top surface to be beaten by a stick and a rear surface opposite to the top surface, a resin member that is strechable and thinner than the knitted material and that is capable of being thermally fused and bonded to the knitted material, and a rubber. The drum pad is formed of a first layer portion, a second layer portion, and a body portion. The first layer portion is formed in a region of the knitted material including the top surface thereof but not including the rear surface. The body portion is formed of the rubber. The second layer portion is formed in a remaining region of the knitted material other than the first layer portion and formed between the body portion and the first layer portion.

    • Grounded, circular movable electrode and divided electrodes, formed on a surface of a circular printed board, are opposed to each other via a double-face tape, functioning also as a spacer, with a slight gap interposed therebetween. As a pad is struck with a stick, the gap between the movable electrode and the divided electrodes changes so that capacitance between the movable electrode and the divided electrodes changes, in response to which signals are output from the divided electrodes. The divided electrodes are sandwiched between the grounded movable electrode and a grounded shielded electrode and thus are not influenced from external disturbances. As the pad is struck with the stick, the gap and hence capacitance between the movable electrode and any of the divided electrodes in the struck position changes, in response to which signals are output from the divided electrodes
    • 形成在圆形印刷电路板表面上的接地圆形可移动电极和分隔电极通过双面胶带彼此相对,双面胶带也起间隔物的作用,其间插有微小间隙。 当焊盘被撞击时,可移动电极和分开的电极之间的间隙改变,使得可移动电极和分开的电极之间的电容响应于从分开的电极输出的信号而改变。 分离电极夹在接地可动电极和接地屏蔽电极之间,因此不受外部干扰的影响。 当焊盘被棒撞击时,可动电极和击打位置中的任何分割电极之间的间隙以及因此的电容响应于哪个信号从分开的电极输出

    • 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.

    • 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.
    • 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。
