Title: Piano playing assisting deevice
Inventor: OGINO HIROSHI
IPC: G10C3/26
Filed: 1994-08-08
Abstract: PURPOSE:To enable even a foot-handicapped person to make playing with the effect similar to the effect of treading on a loud pedal without entailing foot operation. CONSTITUTION:Pressing force acts on an abdomen contact member 10 in an arrow A direction when the foot-handicapped player presses the member by his own abdomen during playing. The pressing force is transmitted to a first connecting part 6. The first connecting part 6 slides in a direction where a second connecting part 8 is pressed, i.e., in an arrow C direction, by receiving the pressing force. As a result, the end member 32 of the second connecting part 8 is pressed and the entire part of the second connecting part 8 is oscillated in an arrow E direction. As a result, a loud pedal lever 42 is oscillated upward by overcoming the energizing force of a spring 46, by which lifting rail jerking up rod 52 is risen. A damper lever 56 is pushed up by a lifting rail 54 which is oscillated by the rising. The damper 58 is thereby parted from a string 60. Then, the musical tones at the time of key touch are reverberated long.

On the other hand, a detection coil 17 outputs a signal in proportion to an oscillation speed of a voice coil. A band pass signal can be obtained by a high band pass filter 19 and a first low band pass filter 20 from an output of this detection coil 17. Also, a noise component can be obtained from an output of the microphone 15 by a second low band pass filter 22. Next, an output of the low band pass filter 20 is made to pass a phase converter 21 and an output of this phase converter 21 and an output of the second low band pass filter 22 are inputted to an adder 23, only the noise around a front side of the speaker unit 13 can be taken out.

Title: Photographing lens, photographing lens system, and camera
Inventor: MORI NOBUYOSHI
IPC: B23K9/02
Filed: 1992-07-14
Abstract: PURPOSE:To satisfactorily compensate the distortion aberration and make the image forming performance excellent with simple constitution by increasing the aspherical surface deformation quantity of the curved surface of a lens on an image formation surface side in the negative direction toward the periphery with the distance from the optical axis of the lens. CONSTITUTION:When a stop is arranged behind the lens, a difference in the position where luminous flux passes through the lens is generated according to the field angle of incidence and each piece of luminous flux is affected by the local curvature of the surface. Namely, the positive distortion aberration increases with the distance of a surface with positive refracting power in front of the stop from the stop and decreases with the distance of a surface with negative refracting power in front of the stop. Here, the aspherical surface decreases in local curvature toward the periphery with the distance from the optical axis, changes in center of curvature from the image formation side to the object side for respective surfaces, and then increases in curvature again. For off-axis luminous flux, the object-side surface varies in refracting power from plus to minus as the field angle is larger and larger and the image side surface varies from minus to plus as the visual field is larger and larger. Namely, the distortion aberration to the off-axis luminous flux is reducible.

Abstract: PURPOSE:To obtain a coil in which the inductance can be adjusted accurately and inexpensively by arranging an insulating resin by a predetermined thickness at least at the joint of two core pieces in order to form a magnetic gap between the two core pieces. CONSTITUTION:An E-shaped core piece 1 is immersed into an insulating resin bath and applied with an insulating resin 2 over the entire surface thereof before being brought into semicured state through pre-baking. A thickness adjusting jig 10 provided with a protrusion 11 having height (t) is then pressed until the protrusion 11 abuts, at the forward end thereof, against a tight contact face 1a being bonded at the time of assembling a core. Consequently, the insulating resin 2 on the tight contact face 1a is deformed plastically into a resin film having a constant thickness (t). The jig 10 is then removed and the insulating resin 2 is cured through post-baking. Finally, a doughnut coil part 5, an I-shaped core piece 3, and the E-shaped core piece 1 are combined into a coil assembly 15. Consequently, inductance of the coil 15 can be adjusted easily and accurately by varying the height of protrusion 11 of the thickness adjusting jig 10.
