Title: Aluminum covered magnetic wire and its manufacture
Inventor: UEJIMA TOKUO
IPC: H01B5/08
Filed: 1998-04-02
Abstract: PROBLEM TO BE SOLVED: To increase an electromagnetic induction calorific value in a low power flow by a method wherein an aluminum covered magnetic wire which is used being wound on an overhead wire in a specific shape is annealed so as to remove its strain. SOLUTION: In the cross-sectional texture of an aluminum covered magnetic wire which is formed in such a way that a magnetic wire is covered with an aluminum layer by an immersion plating method, an Fe-Al-based intermetallic compound layer is formed in the boundary part between the magnetic wire and the aluminum layer, and the boundary part between the intermetallic compound layer and the aluminum layeris set to an amorphous state. When the magnetic wire is annealed at a prescribed temperature, its amorphous boundary part is crystallized so as to disappear, and the clear boundary line between the intermetallic compound layer and the aluminum layer appears in its trace. When the boundary line appears, the removal of a strain due to annealing of the magnetic wire can be judged.  Consequently, the strain which is introduced to the magnetic wire during the manufacture of the aluminum-layer covered magnetic wire is removed by annealing, a sufficiently high magnetic flux density is obtained even in a low power flow, and a snow melting effect can be enhanced.

Title: Complementary signal output circuit
Inventor: SUZUKI MASAYUKI
IPC: H03K17/687
Filed: 1987-04-30
Abstract: PURPOSE:To realize a complementary signal output circuit comprising a MESFET offering ease of circuit integration without losing the driving capability by providing a level shift means additionally to output a normal complementary signal. CONSTITUTION:TR1-TRN are made up of MESFETs, RL1-RL4 are active load resistors comprising depletion MESFETs and D1-D3 are Schottky diodes. A signal fed to the drain of the TR 1 while using the RL1 as the load resistor is outputted inversely at its drain. The TRs 2-4 form a pseudo complementary output circuit similar to a conventional circuit, but even when a level '1' is supplied to the TRs 1, 3, 5, since each gate connects to a Schottky diode (D1-D3), connecting points (a), (b) are clamped to 1.4V and the TR 4 is also driven sufficiently. Thus, the complementary signal output circuit with a normal output is obtained. Since the circuit constitution is manufactured by the same MESFET process, the circuit integration is also facilitated.

Abstract: PURPOSE: To improve the stability of engine control by increasing/decreasing the maximum of the steady state limit at a selected rate while the actual value of operation state parameter increases/decreases to the predetermined maximum value in a gas turbine engine. CONSTITUTION: A comparator 34 of a control circuit 32 compares the predetermined value Y with the number of rotation N2 of a high pressure compressor 12, while N2 is bigger than Y, a switch 38 outputs a coefficient 1, it becomes coefficient R in a multiplier 44, is further rate limited by a limiter 48, and at last a set value Y is added by an adder 52, so a transient limit value is set. And, a difference calculated by a substracter 56 is compensated at a compensator 58 by the engine dynamic characters to becomes a fuel flow rate control value ET. On the other hand, while N2 is smaller than Y, the coefficient becomes zero, the maximum value is reduced. While the control value ET is smaller than steady state and acceleration state fuel flow control values ESS, EA, a minimum selection gate 28 selects the ET and controls the fuel valve 26 corresponding to ESS, EA, ET through an integrator 30. Therefore, the engine runs under a stable operation state.
