Abstract: PURPOSE:To improve magnetic characteristics largely by compressing and treating a rare earth magnet alloy by high pressure of a fixed value or higher. CONSTITUTION:A rare earth alloy 5 housed in a can case 4 under a vacuum is compressed (isotropic compression in this case) at high pressure of 1000kg/cm<2> or more by a pressure medium 6 by using a punch 2. DCs or pulse currents are caused to flow through a coil 3 at the same time as the compression treatment to generate a strong magnetic field, and the rare earth alloy 5 in the can case 4 is compression-molded at constant density. A compression molded form is extracted, and sintered through a rare-earth magnet alloy sintering method, and a sintered body is thermally treated for a change into a magnet and may be magnetized and treated. NdB6, LaB6, Nd15Fe77B8, etc. are employed as the rare earth alloy, and it is preferable that at least one kind of an element selected from a group consisting of B, C, N and H is contained within a range of 1-40 atom % to the alloy.

Title: Method for assigning data in data communication system
Inventor: LEVIN HOWARD E
IPC: H04J11/00
Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To provide a method to assign data while keeping a bit error rate(BER) performance of a system during transmission. SOLUTION: A communication system 30 is provided with a transceiver 42 that transmits data from plural bins. A BER of the bins is substantially equalized especially by deciding a prediction blank so as to assign data. The prediction blank is calculated for each bin by subtracting a reference signal-to- noise value from an estimated bin signal-to-noise value. The reference signal-to- noise is decided in advance by theoretical calculation or empirical data and stored in a lookup table. Bits are assigned to a bin having a maximum estimate blank. Thus, the best BER is obtained without changing a transmission power.

Filed: 1989-06-22
Abstract: PURPOSE:To avoid a change in a temperature of an output current or a power voltage by using a constant current circuit utilizing a baseemitter voltage difference of a couple of transistors(TRs) whose emitter area has a difference. CONSTITUTION:The amplifier consists of a current circuit 1 comprising TRS Q4-Q6, a constant current circuit 2 comprising TRs Q7, Q8 and a resistor R2, a start circuit comprising a resistor R3 and an amplifier 3 comprising TRs Q1-Q3.
