摘要： A phase synchronizing circuit for the demodulation of multi-phase PSK signals has a broadened capture frequency range while avoiding false capture. The circuit includes a phase synchronizing loop having a voltage controlled oscillator for generating a variable frequency output in response to a control voltage and a phase comparator for providing a comparison output representative of the phase difference between the output of the voltage controlled oscillator and an input signal. The comparison output serves as the control voltage for the voltage controlled oscillator. A phase-lock detection circuit is connected to the phase synchronizing loop to detect the phase-synchronized or unsynchronized states of the loop. A low frequency sweep generator is responsive to the phase-lock detection circuit for generating a variable-amplitude voltage which is supplied as a frequency sweep voltage to the voltage controlled oscillator. The frequency sweep voltage is provided for a period of time running from the detection by phase-lock detection circuit of the phase unsynchronized state to a predetermined period of time after the detection of the change from the phase unsynchronized state to the synchronized state.

At least the fixed ring of the bearing rings contains, as alloy ingredients at a ratio of from 0.50 to 1.20% by mass of carbon, from 0.10 to 1.50% by mass of silicon, from 0.1 to 2.0% by mass of manganese, from 3.0 to 6.0% by mass of chromium, 2.0% by mass or less of molybdenum, and 1.0% by mass or less of vanadium, whereby the necessary hardness is obtained and the structure is stabilized. This enables prolongation of the life of bearings.

摘要： A method and an apparatus for detecting a crack in a bearing including a stationary element, a moving element, and a plurality of rolling elements disposed between the stationary element and the moving element. A crack sensor detects a signal characteristic of a crack in the bearing. A rolling element position sensor detects a position of the rolling elements. A moving element position sensor detects a position of the moving element. When an output signal from the crack sensor is supplied for the first time, based on at least one of position signals respectively supplied from the rolling element position sensor and the moving element position sensor, there is determined a condition of the at least one of position signals to be satisfied when the output signal from the crack sensor is supplied the next time. The at least one of position signals is monitored thereafter to accumulate the output signal from the crack sensor if the output signal is supplied when the at least one of position signals satisfying the condition is supplied, to thereby determine whether or not the crack exists in the bearing based on a result of the accumulation.

摘要： A mask-programmed ROM includes depletion type load MOSFETs provided between data lines in a memory array and a power supply voltage, the MOSFETs having a ground potential of the circuit applied to their gates. Reading of data is carried out by an amplifying MOSFET which supplies a current to a selected data line through a depletion type MOSFET which is supplied at its gate with the circuit ground potential. Thus, bias voltages which are respectively applied to the data lines and a sense amplifier which receives a signal read out from a selected data line are made equal to each other, thereby achieving a high-speed read operation.
