Abstract: PROBLEM TO BE SOLVED: To provide a spin valve type thin-film element which makes it possible to obtain good symmetry while maintaining a resistance change rate higher than the resistance change rate of a single spin valve type thin-film element. SOLUTION: A nonmagnetic conductive layer (upper) 22 is formed to a film thickness larger than the film thickness of a nonmagnetic conductive layer (lower) 21, thereby, a free magnetic layer 20 is formed to have a structure asymmetrical in the upper and lower parts thereof. As a result, a difference in intensity occurs between the sense current magnetic field Is1 generated from the lower side of the free magnetic layer 20 and the sense current magnetic field Is2 generated from the upper side of the free magnetic layer 20. The sense current magnetic field Is1, which may be obtd. by the vector sum of the sense current magnetic fields Is1, Is2, can be utilized in order to make the asymmetry 0%.

Title: Howling preventing device
Inventor: OGIWARA TAKASHI
IPC: H04M9/08
Filed: 1981-12-28
Abstract: PURPOSE:To prevent howling in response to the fluctuation at the surrounding, by correcting an impulse response of a pseudo sound path using a temperature electric converter and a variable delay line and subtracting the corrected pseudo sound signal from an input signal of a microphone. CONSTITUTION:A reception signal 22 inputted to input terminal 21 of a reception system is partly branched, applied to a variable delay line 212, delayed and given to a pseudo sound path 213. This output is given to a subtractor 210, where a pseudo sound signal is subtracted from a signal inputted from a transmission system input terminal 28. The delay time of a variable delay line 212 is controlled with an output of a temperature electric conversion circuit 215. The circuit 215 uses conventional temperature sensors. Since the relation between the temperature and sound velocity in air is known, the change in the delay time to the temperature change is known to correct the delay time. Thus, since the change in the delay time accompanied with the temperature change is corrected, echo can be cancelled effectively.

Title: Radial slot board
Inventor: OKAZAKI YASUHIRO
IPC: H01Q21/06
Filed: 1987-08-24
Abstract: PURPOSE:To improve general usefulness by determining two radix points A and B in the point-symmetrical position on the circumference of an arbitrary radius, arranging a slot, which is parallel to a chord BC concerning an arbitrary point C on the circumference, and causing the slot, which is parallel to a chord AC, to be brought into contact with the circumference. CONSTITUTION:The two radix points A and B are determined in the point- symmetrical position on the circumference of an arbitrary radius amm. The slot to have directivity, in which a normal direction passes through one of the A and B, is arranged on the circumference and the slot to have the directivity, whose length-wise direction passes through one of the A and B, is arranged in an inside so that one edge can be brought into contact with the circumference. Thus, when the circumference is arranged in a plural number in order to arrange the slot and the wavelength of an axis-symmetrical propagating mode in a radial conducting path is obtained to be lambda/2mm for a distance to the adjacent circumference, the distance of the lambda/2mm is separated. Thus, a horizontal polarized wave exists in the direction of an X-axis for an antenna, however, the antenna of the vertical polarized wave can be realized by removing a slot pattern by 90 deg..

Filed: 1989-08-16
Abstract: PURPOSE:To enable a wafer where a magnetic body film is formed to be handled even within vacuum in non-contact state by using three electromagnets and a wafer handler with a distance sensor for controlling this strength. CONSTITUTION:Current is allowed to flow from an electromagnet coil controller circuit 22 to an electromagnet 18 of a wafer handler 12 for sucking an magnetic body film 15 of a wafer 13 and suspending it. At this time, and output signal B from a distance sensor 19 of a handler 12 and a value A which is specified to a target interval setting circuit 20 previously are compared by a comparator 21. In the case of A<B, the circuit 22 reduces current to the electromagnet 18, weakens suction force, and then opens the distance between the handler 12 and the wafer 13. On the other hand, in the case of A>B, the opposite operation is performed, thus always maintaining a constant distance. Also it is possible to have at least three electromagnets 18 and sensors 19 and achieve handling in non-contact state without slanting the wafer.
