| 21 | Key actuation systems for keyboard instruments | US11106301 | 2005-04-14 | US07019201B2 | 2006-03-28 | David Meisel |
| A key actuation system that is designed for use with a keyboard instrument of the type having multiple keys. Each key is pivotally supported and has a front end that is depressed by a player to play a note. The actuation system includes multiple actuators that are operable to move at least some of the keys. The actuators together include a block of ferromagnetic material with a surface with multiple bores defined in the surface. Each of the bores has a diameter. A winding is positioned in each of the bores. Each of the windings has a hole. A piston is provided at least partially in each of the holes, with each piston being in mechanical communication with one of the keys such that movement of the piston causes movement of the key. Each piston has a width. A ferromagnetic flux plate with multiple openings is positioned on the surface of the block of ferromagnetic material with the openings aligned with the bores. The openings each have a width that is less than the diameter of the bores, such that the flux plate partially closes off the upper end of each bore. When the windings are energized, the corresponding piston moves, thereby moving one of the keys. | ||||||

| The key actuation system is designed for use with a keyboard instrument of the type having multiple keys. Each of the keys has an upper and lower surface and is pivotally supported above a key bed. A front end of a key may be depressed by a player to play a note. The key bed extends under and is spaced from the lower surface of the key. The actuation system includes an underlever in the space between the lower surface of the key and the key bed, and between the front end of the key in the pivotal support. The underlever has one end that is supported in a stationary position relative to the key bed and another end that is movable towards and away from the key bed. The movable end of the underlever is in mechanical communication with the key such that movement of the movable end of the underlever towards the key bed causes the key to move as if depressed by a player. An actuator is in mechanical communication with the underlever and operable to move the second end of the underlever towards the key bed. | ||||||

| A combined greeting card and decorative music box structure that includes a flat rectangular box formed from a resilient polymerized resin that is removably closed by a cover that on a first side supports a wind-up music producing mechanism within a confined space defined by the box and cover. A second side of the cover removably supports a greeting card. A panel bearing a decorative insignia is pivotally supported from the box, with the panel when in a first position overlying the cover and concealing the greeting card. When the panel is pivoted to a second position the music producing mechanism is actuated and the greeting card is visible. The panel is illustrated as a picture frame that removably supports a picture defined on a dimensionally stable sheet of material. | ||||||

| 本発明は、オルゴールが発する振動音を増幅する拡音板に関するもので、素材固有の方向に沿って曲面に形成した二枚の第一、第二拡音板(14、16)が並列に配設され、オルゴールムーブメント(12)を装着した上縁を除く全周縁が支持部材(18、19)及び基台(20)に固定される。拡音板(14、16)曲面の縦断面が画く曲線の接線に沿って振動が伝達されるようにムーブメント振動板(32)の面は拡音板(14、16)上縁を含む接平面(P)に対して垂直に配置される。ムーブメント(12)で発生する振動音は、拡音板(14、16)の上側端部せつ断面の木口およびその近傍から入力される波動の励振が拡音されるからエネルギーロスが少ない。 | ||||||

| PURPOSE: To provide an automatic playing device which is free from the damage caused by continuous power supply to an apparatus like a solenoid even in the case of runaway or stop of a program due to some abnormality. CONSTITUTION: A relay switch and a power control circuit which closes this relay switch only at the time of giving an alternating signal are arranged in a solenoid power supply circuit, and the processing to output an inverted signal to a power remote terminal is added to the last of a reproducing routine (S26). Since a recording/reproducing program is repeatedly executed at intervals of 5msec, the alternating signal of 100Hz frequency is outputted as the power control signal when the reproducing mode is normally executed. If the program is run away or stopped, execution of the reproducing routine is stopped, and the power control signal is not inverted, and therefore, the relay switch is opened, and power supply to the solenoid is forcibly turned off.
