Title: Self-compress air speaker
Inventor: NAKAMATSU YOSHIROU
IPC: H04R9/02
Filed: 1978-12-28
Abstract: PURPOSE:To realize a self-compressor air speaker whose vibrating part is floated in the air by compressing air in an airtight box through the vibration of the diaphragm of the speaker fitted in the airtight box. CONSTITUTION:A woofer and tweeter are fixed to box 16 so that box 16 will be sealed, and unidirectional valve 17 is fitted to box 16. Then, diaphragm 13 vibrates by a current flowing through voice coil 6 and air in box 16 is compressed in consequence and pushes horizontal and vertical inner walls of cylindrical bobbin 14 by way of horn 24 and hole 12 of a magnetic circuit. As a result, bobbin 14 floats in the air away from support cylinder 23 and center pole 10. At the same time, the compressed air lets the tweeter float similarly. In this way, a self-compress air speaker requiring no compressor can be obtained.

Abstract: PURPOSE:To uniformly and stably disperse magnetic material particles into magnetic coating material by plasma processing of magnetic powder under the existence of organic material. CONSTITUTION:A magnetic material powder is subjected to plasma processing under the existence of organic material. When the magnetic material powder is processed by plasma under the existence of organic material, surface of magnetic material particle and organic material are activated, and magnetic material particle and lipophilic organic material are coupled strongly by such activation. Moreover, since magnetic material particles are uniformly covered with organic material, recoupling of particles occurs.

Title: Josephson device
Inventor: YAMADA YASUHARU
IPC: G01R33/035
Filed: 1992-06-22
Abstract: PURPOSE:To obtain a Josephson device having a construction with less possibility of trapping magnetic flux at the time of adjustment of critical current, by forming wiring on a Josephson junction through the medium of an insulating layer, connecting a part of the wiring to only one of electrodes and taking out the other end to the outside, and causing current to flow. CONSTITUTION:A current source is connected and pulselike current is caused to flow in the order of the current source-a lower electrode 2-bridges 5a and 5b-an upper electrode 4-wiring 7-the current source, and its magnitude is made to be the critical current or more of the bridges 5a and 5b. Then, the bridges 5a and 5b generate heat, and oxygen from Nb2O5 diffuses to the surface and oxydizes its part. As the result, junction critical current lowers. On this occasion, current flowing directly in the bridges 5a and 5b and that flowing in the wiring 7 just above them are opposite in direction, and the directions of magnetic fluxes generated by these are opposite to each other and are canceled. Accordingly, magnetic flux to be trapped in the Josephson junction decreases sharply.
