Title: Manufacture of wound core
Inventor: FUKAGAWA KIMIHIRO
IPC: H01F27/25
Filed: 1985-06-21
Abstract: PURPOSE:To elevate the temperature of a wound core under uniform temperature distribution, and to anneal it in a short time by dividing an amorphous magnetic alloy sheet metal for the wound core into a division layer on the outer circumferential side in small winding thickness or plate width and a division layer on the inner circumferential side in large winding thickness and discretely exciting the divided layers at high frequency. CONSTITUTION:When the sectional area of a divided layer 11a on the outer circumferential side of a wound core 11 is represented by S1 and the sectional area of a divided layer 11b onn the inner circumferential side by S2, the magnetic flux density B1, B2 of several divided layer 11a, 11b is represented by B1=PHI/S1 and B2=PHI/S2 respectively because the magnetic flux PHI of respective division layer 11a, 11b by separate high-frequency excitation by an exciting coil 15 is of one magnitude. Since the sectional area S1 of the division layer 11a< the sectional area S2 of the divided layer 11b holds at that time, B1>B2 holds in the magnetic flux B1, B2 of each divided layer 11a, 11b. Accordingly, the layer 11a is excited at magnetic flux density higher than the layer 11b and generates heat, thus elevating the temperature of the outer circumferential section of the wound core 11 having an excellent cooling condition at the same temperature as an inner circumferential section.

Title: Channel detour switching system

Filed: 1988-06-03
Abstract: PURPOSE:To attain the alternative connection of channels without using a remote supervisory circuit and a logical decision circuit by providing single frequency oscillation circuits, single frequency detection circuits, channel detaching circuits and channel connection circuits in correspondence with a terminal and another respective stations. CONSTITUTION:When a channel becomes abnormal between stations B and C, a single superimposed frequency from a station A is interrupted, whereby the single frequency detection circuit 6 of the station C detects abnormality. The channel detaching circuit 8 which operates after a prescribed time detaches the channel 1, and the single frequency oscillation circuit 10 is simultaneously started, whereby the single frequency is re-inserted into the direction of the station D. Since the operation start time of the circuit 8 in the station D is set later than that in the station C, the single frequency is received and the circuit 8 is prevented from operating. A channel connection circuit 12 inputs the interruption of the single frequency which the circuit 6 of its own station has detected, connects the channel 1 and an alternative channel 2 and connects information between the stations B and C through the channel 2. Since the circuit 10 stops at the time of restoration, the circuit 6 detects the interruption of the single frequency and the circuit 12 is switched from a connection state to a detaching state.

Abstract: PURPOSE:To obtain a power level adjusting device having a broad band characteristic and being able to cope with large power by connecting a variable reactance and a matching load to a circulator so as to constitute the assembly as a reflecting type power level adjusting device. CONSTITUTION:When the reactance of a variable reactance element 3 is large through the adjustment of a bias power supply 4, a microwave band signal inputted from a terminal 51 through a circulator 1 is reflected. Its reflection signal is given to the circulator 1 and outputted from a terminal 52. When the reactance of the element 3 is small, the microwave band signal from the circulator 1 is absorbed by a matching load 6 via a DC voltage block capacitor 5 and no reflecting wave is caused and not outputted to the terminal 52 of the circulator 1. Thus, the quantity of reactance is made variable by the adjustment of a bias voltage, the signal of the microwave band is subjected to power adjustment and outputted. Moreover, the matching of the impedance as a microwave circuit is excellent and the circuit can cope with high power.
