    Abstract: PROBLEM TO BE SOLVED: To obtain a resistor which has very small variations depending on the power and is suitable as a high-precision power resistor for electric current detection. SOLUTION: This high-precision power resistor which has small variations in resistance which depend on power, is equipped with a substrate, having a first flat surface and a second flat surface which face each other and respectively have a predetermined shape and a predetermined composition, and a first resistive foil, which is bonded to one of the flat surfaces with a bonding agent and has a low TCR of approximately 0.1 ppm/°C, to approximately 1 ppm/°C and a thickness of approximately 0.03 mils to approximately 0.7 mils. The first resistive foil is patterned so as to give the desired resistance. The modulus of elasticity of a substrate is set to, approximately 10×10 6 psi to approximately 100×10 6 psi, and the substrate thickness is set to approximately 0.5 mils to approximately 200 mils. The type of the resistive foil, pattern, and bonding agent, the bonding agent thickness, and the substrate should be selected so as to produce cumulative effects on the reduction of variations in the resistance due to the power. This invention is for a manufacturing method of high-precision power resistors. COPYRIGHT: (C)2004,JPO

    Abstract: PROBLEM TO BE SOLVED: To provide an RF modem which has frequency agility, is simple to implement, and can be constructed at low cost and small size.SOLUTION: A bidirectional direct sequence spread spectrum half-duplex RF modem for transmitting and receiving analog and digital pulse modulation incorporates a SAW based correlator for performing the spreading and de-spreading functions in the transmitter and receiver. A programmable frequency synthesizer provides the frequency source for various signals in the modem including a local oscillator (LO), IF interrogating pulse and clock signals. An upconverter/downconverter provides frequency translation to a desired frequency band. Pulse gating and interrogating pulse shaping reduce the spectral side bands of a transmitted spread pulse. The RF modem operates as an analog or digital pulse transmitter and receiver and is applicable in data communication systems such as OOK, PWM and PPM.
