Title: Stratified eddy current type coil for strong ac magnetic field
Inventor: BESSHO KAZUO
IPC: H01F5/00
Filed: 1988-08-08
Abstract: PURPOSE:To operate the title coil over a wide frequency range by constructing the coil out of a conductor plate for an eddy current having a slit and a conductive material coil for eddy current excitation around which a conductive material is wound into a flat plate annular shape. CONSTITUTION:Flat plate annular conductive material coils 4a, 4b are successively coupled at ends 5b, 6a thereof, and annular insulators are disposed between the coils 4a, 4b and circular conductor plates 1a-1c for electrical insulation between the latters. Herein, once an AC voltage is applied across the ends 5a, 6b, an AC magnetic flux is generated by an AC current 7, and hence an eddy current flowing oppositely to the current 7 is formed around edges of the conductor plates 1a-1c and allowed to flow peripherally of the conductor plates. Further, the eddy current is allowed to flow along slits 3a-3c in the conductor plates radially of the same and concentrated around the periphery of a hole 2, and an eddy current 10 is allowed to flow in the same direction as that of the current 7 to form an AC magnetic field in the hole 2. The just- mentioned magnetic flux and one due to the current 7 are in the same direction and hence superimposed and added to each other.

Title: Sound reproducer and method
Inventor: RIYUKA FUABURIIKONTEI
IPC: H04R1/30
Filed: 1989-07-28
Abstract: PURPOSE: To make it possible to largely displace a movable coil without generating dangerousness accidentally bringing a diaphragm into contact with a mouth part by forming the diaphragm as a part of an wall of a horn in an input area. CONSTITUTION: In a 1st part of an input area 23, the displacement of the diaphragm 20 includes air of small capacity and pressure is substantially changed as the result of a narrow interval up to the wall. In a final output area 26, the displacement of the diaphragm 20 includes air of large capacity and pressure is slightly changed because the interval between the diaphragm 20 and the wall arranged so as to be mutually opposed is sufficiently large. When a distance from the input area is increased, the accumulated impedance of a preceding capacity part is made larger than the impedance of a succeeding capacity part. Consequently the movable coil can be extremely largely displaced without generating dangerousness accidentally bringing the diaphragm 20 into contact with the mouth part.

When the trigger clock reaches H-level, a flash current flows through the waiting flash discharge tube 4. The flash discharge tubes 3, 4 emit light alternately and synchronous with the trigger clocks.
