Title: Spring installing length regulating mechanism
Inventor: TSUKAHARA KINJI
IPC: F02G1/053
Filed: 1991-03-29
Abstract: PURPOSE:To convert the length of instilling a spring freely by opening and closing valves to suck and exhaust the oil in oil chambers into a casing, and thereby expanding and contracting a bellows to increase and decrease the pressing force of a spring to a piston. CONSTITUTION:Inside a casing 1, a piston 2 to reciprocate in a specific scope, a spring 3 to hold the piston 2, and a bellows 5 unitary with a valve seat to hold the spring 3 are provided respectively. And the inside of the bellows 5 is connected to a low pressure oil chamber 8a and a high pressure oil chamber 8b respectively through pipes 6 and plural valves 7a and 7b set at the outside of the casing 1. As a result, when one side valve 7b, for example, is opened, the oil flows in the bellows 5 from the high pressure oil chamber 8b to expand the bellows 5, and thereby, the pressing force is increased to the piston 2 through the spring 3. Consequently, by regulating the oil capacity in the bellows 5, the optimum spring reaction can be set constantly.

Title: Electrodinamic speaker
Inventor: INOUE HIDEAKI
IPC: H04R9/06
Filed: 1981-06-10
Abstract: PURPOSE:To decrease the thickness of a speaker without lowering the density of the magnetic flux within a magnetic gap which forms a magnetic circuit, by supporting a diaphragm with a damper in a recessed part forming the magnetic circuit. CONSTITUTION:For a magnetic circuit, the upper and lower plates 7 and 10 are attached close to the upper and lower surfaces of a magnet 8 having a larger diameter than a diaphragm 1 and a magnet 9 which is positioned at the inner circumference side of the magnet 8 with the smaller thickness than the magnet 8, and a recessed part 2 is provided on the upper surface of the plate 7. In this connection, a voice coil bobbin 5 of the diaphragm 1 is shortened, and the diaphragm 1 is set close to the plate 7 and can be supported with a damper 6 within a recessed part 12. Thus the diaphragm 1 can be supported by the damper 6, a voice coil 4, etc. with a sufficient margin of amplitude. As a result, the overall thickness can be decresed for a speaker. While the magnet 8 has a larger diameter than the diaphragm 1, and accordingly the thickness of the magnet 8 itself can be increased. Thus no reduction is cauased to the density of the magnetic flux within a magnetic gap 11 which forms a magnetic circuit.
