    Abstract: A rare earth-iron permanent magnet which is formed from an ingot of an alloy composed of at least one rare earth element represented by R, Fe, B and Cu, by the hot working at 500.degree. C. or above which refines the crystal grains and make them magnetically anisotropic. A process for producing a rare earth-iron permanent magnet by subjecting the ingot of said alloy to hot working at 500.degree. C. or above. The permanent magnet is equal or superior in magnetic performance to conventional permanent magnets produced by sintering method. The process is simple and able to provides permanent magnets of low price and high performance. In addition, an isotropic rare earth-iron permanent magnet is obtained if said ingot undergoes heat treatment at 250.degree. C. or above.

    Abstract: A coin selecting apparatus includes a coin detection coil disposed in a coin channel for outputting a coin detection signal having a waveform changing gradually as the coin passes in the channel and uniquely accordance with the kind of the coin, and window device having a plurality of different windows for corresponding coins to be detected for producing a pulse signal when the coin detection signal is in a window. A timer device monitors the time duration of the pulse signal to thereby determine the validation and kind of the coin in accordance with the output from the timer device. A counter counts pulse signals produced by the window device to thereby determine the validation and kind of the coin in accordance with the count therein.

    Abstract: The delta-sigma modulator includes a secondary delta-sigma modulator which carries out a secondary delta-sigma modulation for an analog input signal, thereby producing a first quantization signal. A quantization noise extractor extracts a quantization noise occurring in the secondary delta-sigma modulator. A primary delta-sigma modulator carries out a first delta-sigma modulator for the quantization noise, thereby producing a second quantization signal. A differentiating circuit differentiates the second quantization signal supplied from the primary delta-sigma modulator. An adder adds the first quantization signal and an output signal of the differentiating circuit, thereby producing a digital output signal corresponding to the analog input signal.

    Abstract: A voltage level setting circuit sets a voltage level of a predetermined portion of an input signal received through a coupling capacitor to a desired reference voltage level suited for a signal processing which is carried out in a signal processing circuit, where the voltage level of the predetermined portion is used as a reference level of the input signal. The voltage level setting circuit comprises a charge injecting circuit for injecting a quantity of charge to a node between the coupling capacitor and the signal processing circuit, and a control circuit for controlling the injection of charge by the charge injection circuit responsive to a signal from the signal processing circuit so that the voltage level of the predetermined portion at the node is set to the desired reference voltage level.

    Abstract: A coin tube cassette is detachably mounted in a coin dispensing apparatus and has a plurality of coin tubes for storing coins in the direction of thickness thereof and coin shoots in units of denominations of coins stored in the radial direction thereof. The coins are automatically replenished by coin selector gates in the coin tubes or the coin shoots until they become full. A selected coin is discharged from the coin tube or the coin shoot in response to a code set by a code setter in accordance with the type of the tube cassette and the denominations of coins stored in the coin tubes. Coin dispensing is performed by a rotary disk having grooves for receiving coins and a coin selection plates having slits. The coin tube or the coin shoot is selected by a single solenoid.
