Title: Electrodynamics acoustic transducer with magnetic gap seal
Inventor: MARTEN STEFAN
IPC: H04R9/02
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To prevent an acoustic short circuit by providing a projecting coil into an air gap which is exposed to an electromagnetic field and sealing the air gap with a liquid such as iron power liquid, etc., or a solid medium. SOLUTION: Inside and outside air gaps 14 and 15 are formed by the projection of a coil 3 into an air gap 4 between a pole flange 5 and a cup 6. An arrow 16 in a diagram shows lines of magnetic flux which originate from the flange 5 into the cup 6. Furthermore, iron powder fluid 21 is placed as a viscosity medium in the gap 15. While the lines of magnetic flux come into the fluid 21, the fluid 21 automatically moves to the part of the gap 15 where magnetic field strength becomes maximum because of its magnetic property. Thus, by placing liquid like the liquid 21 or a solid medium in the gap 15, the gap 15 is sealed and therefore, the connection between the capacity at the back of a film 2 and the one 18 in front of the film 2 is prevented.

Title: Thermosensitive optical element
Inventor: NOGAMI TAKASHI
IPC: B41M5/36
Filed: 1986-03-26
Abstract: PURPOSE:To obtain the titled element having an improved responsibility by using diazabicyclo(2,2,2)octan quaternary salt as a medium. CONSTITUTION:The diazabicyclo(2,2,2)octan quaternary salt is used as the medium. The medium shows the property in which birefringence displays at a temp. lower than the transition temp. of the medium due to antisotropy of the crystal, and this birefringence disappears at a temp. higher than the transition temp. of the medium by effecting a phase change bounding a prescribed temp. Therefore, the light projecting from the medium changes bounding the transition temp. As the prescribed medium displays the phase change with very sensitivity, and any chemical change of the medium does not occur, the medium has an excellent stability and hysteresis does not remain in a repeating use.

Title: Manufacture of semiconductor device
Inventor: FUJII TETSUO
IPC: H01L21/8247
Filed: 1989-03-20
Abstract: PURPOSE:To improve film quality, and further improve endurance characteristics and dielectric breakdown life characteristics of, e.g. a nonvolatile semiconductor storage device, by heating a nitrided oxide film in the state where pressure is reduced or inert gas is introduced. CONSTITUTION:An oxide film is formed on the surface of a semiconductor substrate 32; in a chamber 31 in which nitrogen system reaction gas is introduced, the substrate is rapidly heated and nitrided, thereby forming nitrided oxide films on both surfaces of the oxide film; the pressure inside the chamber 31 is further reduced, and heating is performed, thereby eliminating residual material which has not yet reacted in the nitride oxide film. By heating process in this manner, the residual material which has not yet reacted in a tunnel oxide film can be eliminated. However, if the pressure is reduced, the residual material which has not yet reacted can be more sufficiently eliminated, so that the pressure reduction is desirable. Thereby the quality of an oxide film formed on the semiconductor substrate 32 is improved, and endurance characteristics and dielectric breakdown life characteristics of, e.g. a nonvolatile semiconductor storage device can be further improved.

Abstract: PURPOSE:To obtain shielding materials whose electromagnetic shielding characteristics are excellent, and whose characteristic deterioration due to strain and characteristic changes with the passage of time are small, by constitut ing the materials specifically and making them contain minute crystal particles at a rate of at least 50% of the formation. CONSTITUTION:Materials of this invention have constitution expressed by equa tion I. At least 50% of the formation is minute crystal particles, and the materials comprise of alloys whose average crystal particle diameter is less than 1000Angstrom . In equation I, M, M, M, or X is at least one kind of element chosen from Co and/or Ni; Nb, W, etc.; V, Cr, etc.; or C, Ge, etc., respectively. Symbols (a), (x-z), and (alpha-gamma) satisfy 0<=a<0.3, 0.1<=x<=3, 0<=y<=25, 3<=z<=17, 10<=y+z<=30, 0.1<=alpha<=10, 0<=beta<=10, and 0<=gamma<=10. As the reciprocal action param eter between Cu and Fe is positive, and their soluble degrees are low, they tend to separate and many easily crystallizable domains are produced partially. Minute crystal particles are produced having the domains as nucleuses. This makes possible obtaining electromagnetic shielding materials whose electromag netic shielding characteristics are excellent, and whose characteristic deteriora tion due to strain and characteristic changes with the passage of time are small.
