Title: Magnetic reproducing device
Inventor: NAKAMURA HITOSHI
IPC: G11B5/39
Filed: 1990-11-30
Abstract: PURPOSE:To attain a narrow gap and to obtain high reproducing efficiency by combining the magneto-optical effect and a magnetoresistance sensor and reading the direction of magnetization recorded on a medium by the magneto- optical effect. CONSTITUTION:The subject device is provided with a circuit for detecting the direction of magnetization recorded on the magnetic recording medium by the magneto-optical effect and changing a sign of a voltage change between terminals corresponding to a resistance change of the magnetoresistance sensor by the direction of magnetization of the medium. That is, the magnetic recording device is composed of the recording medium, the magnetoresistance sensor and moreover a reproducing system (Kerr effect) having the application of the magneto-optical effect. In this case, since a Kerr rotary angle is changed by the direction of magnetization of the recording medium, the direction of magnetization can be obtained from the intensity of a Kerr signal. Moreover, the absolute value of the Kerr signal intensity is not important, and it is enough to obtain an S/N (signal output/noise output) required for deciding whether the direction of magnetization from the Kerr signal intensity is 1 or 0. By this method, a narrow gap is formed, and a high reproducing output is obtained.

IPC: G01N3/20
Filed: 1990-11-30
Abstract: PURPOSE:To make continuous tests possible irrespective of specimen shapes by constituting so that one of vertically movable upper and lower holders inserted with a small gap maintained between each other is made rotatable relative to its holding arm. CONSTITUTION:A specimen S2 is placed on support pieces 7. Operating a holding arm 2, a pressure piece 12 is set to the position for coming in contact with the top surface of the specimen S2. When an upper holder 1 is raised, a receiving table 4 is lifted. While the central portion of the specimen s2 is restrained with the pressure piece 12 fixed to the lower holder 9 and cannot move, its right and left ends are bent upward as the support pieces 7 rise. Even if the specimen S2 tends to roll aside, the specimen S2 cannot roll aside and come off because the holders 1 and 9 are fit to each other and do not deform more than a certain angle even if they are forced to bend in the middle as allowed by a small gap G. Even if the position of the specimen S2 is inappropriate and comes off, it comes in contact either of the holders and does not come off the testing machine.

Title: Antenna device
Inventor: SOE TAKESHI
IPC: H01Q7/00
Filed: 1997-12-09
Abstract: PROBLEM TO BE SOLVED: To provide a miniaturized antenna device with a higher degree of freedom by providing a gap between a radiation electrode and an excitation conductor and connecting them electromagnetically through a capacitance formed in the gap. SOLUTION: In the proposed antenna device, an excitation conductor is formed only on the side 1c of a dielectric substrate 1, and the upper end of the excitation conductor faces a radiation electrode 2 through a gap 6. The gap 6 is provided between the loop-like radiation electrode 2 and the excitation conductor, wherein they are electromagnetically connected through capacity formed in the gap 6. Thus, excitation occurs without contact and even an inverted-f antenna using a λ/4 resonance mode in addition to a loop antenna can easily be matched. Since capacitance of an imaginary component increases by feeding power through electromagnetic field, the impedance value is reduced. Thus, a point with an imaginary component = 0 moves to a frequency around R=50 Ω and matching is realized.
