Filed: 1985-10-04
Abstract: PURPOSE:To obtain a facsimile unit which is simple in structure and can efficiently decode and record received pictures by using a program control means such as microprocessor for decoding. CONSTITUTION:The signal transmitted through the telephone line passes through a net control unit 5 and is input to an MODEM 6 in which it is converted from an AC signal into unbinary facsimile signal 6-a. A delay circuit 8 is so provided that it sends an FIFO shift impulse 8-1 after a parallel output 9-a of a shift register 9 is sufficiently stabilized.

Title: Radio direction finder
Inventor: KAGAYA HIROSHI
IPC: G01S3/74
Filed: 1985-10-08
Abstract: PURPOSE:To make a one-image-plane display without any flicker even when many bearings are alternately displayed on a time-division basis by imposing time-division rectangular wave modulation upon plural display signals and displaying them on one cathode-ray tube distinctively at the same time. CONSTITUTION:A radio wave received by an antenna group 1 is switched by an antenna switch 2 successively and its output is distributed to receivers 4 by a distributor 3. If the radio wave is received by only a receiver 4-1, a bearing signal is obtained by a detector 5-1. This signal is applied to an amplifying circuit 6-1 and controlled by its internal frequency correcting circuit with reception frequency information so as to obtain an output which is invariably constant regardless of the reception frequency. This output is applied to a video signal generating circuit 9-1 through a bearing signal frequency converter 8 to obtain signals X1 and Y1. At this time, a bearing signal frequency converter 8 increases the frequency of the bearing signal by (m) times (m: optional integer) and the result is displayed. Therefore, even when many bearing lines are displayed at the same time, there is no decrease in display time, so a flicker is eliminated.

Filed: 1990-08-24
Abstract: PURPOSE:To obtain a superconductor which can be covered with a thin enameled insulating layer at a low cost by joining a stabilizing metal and an Nb-Ti alloy superconducting wire with a brazing filler metal whose melting point is specified. CONSTITUTION:Stabilizing metal 3 and Nb-Ti alloy superconducting wire 1 are joined with a brazing filler metal 2 whose melting point is of 320 deg.C-620 deg.C. By using Zn as the brazing filler metal 2 for example, the wire 1 is heated and joined, and thereafter, it is bake coated with formal 4 at 300 deg.C. The melting point of Zn is 420 deg.C and higher than the temperature at which the formal 4 is bake coated on the wire 1, so that the brazing filler metal 2 is not molten and therefore, their joinability is good. If the temperature exceeds 620 deg.C, the characteristics of Nb-Ti alloy superconducting wire 1 are deteriorated by heat at the time of joining with the barzing filler metal. It is thereby possible to apply enameled insulation at a low cost and thin the insulating covering layer.
