Title: Method for orienting crystal of material
Inventor: KAWAHARA NOBUAKI
IPC: C30B33/04
Filed: 1990-02-23
Abstract: PURPOSE:To obtain the material having the degree of orientation of the crystals homogeneous from the surface to the inside by applying a magnetic field gradient on a material having electrical anisotropy in such a manner that the part of the strong magnetic field and the part of the weak magnetic field act thereon. CONSTITUTION:The magnetic field gradient is applied to the material having the electrical anisotropy in such a manner that the part of the strong magnetic field and the part of the magnetic field weaker than the magnetic field of this part act on the material at the time of orienting the above-mentioned the crystals by imparting a compressive stress thereto. The crystals on the front surface side of the material are oriented by the impartation of the pressure in the above-mentioned method. On the other hand, an eddy current flows in the material having the electrical anisotropy from the part of the strong magnetic field effect to the part of the weak magnetic field effect, i.e. in the direction where the magnetic field is intensified as against a decrease in the magnetic field. The Lorentz force by the eddy current and the magnetic fields is, therefore, generated and the crystals in the material are so oriented that the wide surface thereof is perpendicular to the direction of the magnetic fields.

Title: Optical fibre gyro scope device
Inventor: INABA RITSUO
IPC: G01C19/72
Filed: 1991-03-08
Abstract: PURPOSE:To obtain a fibre gyro scope that has a short fibre length, by propagating at a closed propagation passage pulselike photosignals plural times in mutually opposite directions. CONSTITUTION:A half mirror 17 is provided between a beam splitter 13 and a photodetector 16. A pulselike signal having a predetermined time interval is used as a photosignal, and when the pulselike photosignal finishes its action in which an optical fibre transmission passage is propagated plural times, the next signal is inputted. For example, given that a photosignal is transmitted at the pulse of 1 microsecond and a fibre transmission passage is made to be 100m equivalently, propagation is completed after the elapse of 3.3 microseconds. Meanwhile, the half mirror 17 propagates the photosignal plural times in the optical fibre 25, and returns it to the fibre 25 by reflecting half of the light. The photopulse arrives, and reflects again and propagates in a direction opposite to the previous one and returns again to the photodetector 16 by following the same form as the first one. A long propagation length is obtained by means of a short optical fibre by making photooutput after propagation interfere and turning it into an optical fibre gyro scope device that takes out a signal corresponding to an angle speed.

Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to perform bonding stabilizing the side of a lead and preventing its exfoliation, and to increase the reliability by forming insulating coats of a covered wire with spaces. SOLUTION: Insulating coats 5 of a covered wire are formed with spaces.
