Title: Method for driving current stretch type magnetic bubble expander/eraser
Inventor: MIZUNO KENJI
IPC: G11C19/08
Filed: 1986-03-19
Abstract: PURPOSE:To prevent a bubble from jumping out of a bubble expander/eraser when the bubble shrinks after being expanded by the bubble expander/eraser by allowing the 1st current pulse to be trailed according to, for example, a ramp function or exponential function. CONSTITUTION:When the bubble is moved along a major line 11 and reaches a cusp 12, a current pulse 1 is supplied to the bubble expander and eraser 14. Then, the current pulse 1 is made to be trailed according to the ramp function after the bubble is expanded and detected, and the bubble is held inside the bubble expander/eraser 14 and then erased with the 2nd current pulse 2 which is different in polarity. Consequently, an erasure pulse phase margin can be expanded >=1.5 times by a conventional method and no bubble jumps out of the bubble expander/eraser, so that a large operation margin is obtained.

Title: Measuring system of error rate in radio transmission system
Inventor: TOMINAGA YOSHIMI
IPC: H04L1/00
Filed: 1983-04-11
Abstract: PURPOSE:To measure automatically an error rate by sampling a reception-side signal with a signal resultant from the logical operation between a signal having one-bit width, which is obtained by detecting a frame of a received pattern, and a signal having frame width which is reduced to one of the number of phases of transmission phase modulation and obtaining pull-in phase information as a digital output. CONSTITUTION:The output of a pattern generator PG is connected to the input side of a transmitter, and an attenuator ATT is connected between the output of the transmitter and the input of a receiver, and an pull-in phase display circuit PDP is connected to the output of a receiver-side sampling circuit SMP, and an error rate measurer ERM is connected to the output of a reception-side logical operating circuit R-LOG. A signal P obtained by reducing the output of the pattern generator PG to 1/(the number of used transmission and reception phases), for example, 1/4 is inputted to one terminal of an AND operating circuit AND. Meanwhile, the output of the pattern generator PG is subjected to sum processing in a transmission-side logical operating circuit T-LOG and is subjected to +N vector rotation by the carrier pull-in phase of a receiver demodulator DEM. This output is subjected to difference processing in the reception-side logical operating circuit R-LOG to become an original pattern.

Title: Control instruction arithmetic processor
Inventor: NAGAO SATORU
IPC: G05B19/02
Filed: 1994-03-31
Abstract: PURPOSE:To execute a control instruction at high speed by synchronizing the operation of a POL emulator and the instruction execution of a POLG and minimizing the overhead of the operation of the hardware of the POLG and the operation of the POL emulator. CONSTITUTION:Both a general-purpose muP 1-1 and a POLG 1-2 do not hold any other processor during their operations but the POLG 1-2 is synchronized by the bus access of the general-purpose muP 1-1. Therefore, the overhead caused by hand shake processing or competition processing between the muP and the POLG can be eliminated. By showing the arithmetic result of the POLG 1-2 in POL status returned by read access from the muP 1-1 to the POLG 1-2, the state of executing the instruction at the POLG 1-2 can be recognized by the muP 1-1, and the next instruction can be started at high speed as well. On the other hand, since a CDIF part is provided with a function for identifying the executing part of each POL instruction, it is judged whether the instruction is an H/W executing instruction to be executed by the POL emulator of the muP or an H/W instruction to be executed only by the POL.

Title: Magnetic field detecting device
Inventor: YOKOZAWA KOICHI
IPC: A61B5/055
Filed: 1989-03-17
Abstract: PURPOSE:To uniform the sensitivity of each detector by arranging all or some of detectors for brain magnetism measurement at the vertexes of a regular polyhedron. CONSTITUTION:The detectors which forms a gradiometer detects a signal of brain magnetism generated by a person 6 to be examined and inputted to a SQUID element through a transmission line 5. This signal is measured by a measuring instrument which uses, for example, a flux locked loop. Further, a controller controls the measuring instrument and a rotary mechanism. The detector 1 and transmission line are made of superconductors, so a mechanism part 100 has its inside dipped in a blocking material of liquid He when necessary. The detectors 1 are arranged all the vertexes of, for example, a regular dodecahedron 10. In this case, up to 20 detectors can be arranged, but there is a vertex where a detector can not be arranged because of mounting. Further, while the whole mechanism is rotated around the person 6 to be examined by selecting its axis properly, measurement is only carried out to obtain more measurement points. Thus, the detectors 1 can be arranged equally and spherically, so the detectors 1 can be equalized in sensitivity.

Title: Oxide high-temperature superconductor and thin film superconductor therefrom and sputtering target therefor
Inventor: KITAHATA MAKOTO
IPC: H01L39/24
Filed: 1988-03-17
Abstract: PURPOSE:To obtain the title superconductor with enhanced critical current density by incorporating an oxide high-temperature superconducting material with specified amount of S, Se or Te. CONSTITUTION:The objective superconductor is such that S, Se or Te satisfies the relationship. Such amount of the S, Se or Te enhances the critical current density of said superconductor. If the amount of the S, Se or Te exceeds the range given in the relationship, said element not only enters oxygen site, but also separates out, e.g., on the crystal grain boundary, thus deteriorating the superconducting nature. Specifically, the objective thin film superconductor can be obtained by forming, through the sputterling process, on a substrate a composite compound film consisting mainly of A', B, Cu and O with S, Se or Te satisfying the relationship (where, A' is Sc, Y, La-series element, Tl and/or Bi; B is at least one kind of element classified as group IIa elements). The other objective sputterling target is, e.g., as the chief component, a mixture or compound made up of A'Ox and A'Sw (w, x>=0).

Filed: 1984-03-30
Abstract: PURPOSE:To provide a thermosensitive device which has an extremely small hysteresis range and good repetitive service life characteristics by forming an NiTi shape memory alloy in such a way that the two-way motion combined with bias load is the displacement to change the crystal structure of the alloy from a cubic crystal to a rhombohedral crystal when cool and is the displacement reverse thereto when heated. CONSTITUTION:This invention is obtd. as a result of studying the relation between the hysteresis and service life of the two-way motion of a shape memory alloy (MSA) consisting of an NiTi alloy system. More specifically, the two-way motion combining bias load with said MSA is made into the displacement by the transformation of the crystal structure of said MSA changing from a cubic crystal (B2 phase) to a penta-rhombohedral crystal (R phase) when cool and to the displacement by the transformation restoring the B2 phase from the R phase when heated. The provision of the intended thermosensitive device of which the hysteresis of the two-way direction is <=3 deg.C and the change of the working temp. and permanent set in fatigue are considerably decreased in the repetitive service life is made possible by the above-mentioned limitation of the motion.
