  • Patent number: 8922263
    Abstract: The power consumption of a data sampling unit that selects a phase of a clock signal appropriate for sampling payload data is reduced at an input interface. A semiconductor integrated circuit includes an input interface and internal core circuits. The input interface includes a hysteresis circuit and a data sampling unit. The hysteresis circuit detects an input signal between first and second input thresholds as a sleep command. The data sampling unit selects an appropriate phase of a sampling clock signal in accordance with a synchronizing signal and samples payload data. When a sleep command is detected, a sleep signal is also supplied to the internal core circuits and the data sampling unit and they are controlled into a low-power consumption state.

    Abstract: A centrifugal-pendulum vibration absorbing device, including a member attached coaxially with a rotary element; and mass bodies swingably coupled to the support member and disposed adjacent to each other in a circumferential direction. The mass bodies are configured such that when a first mass body, which is one of two mass bodies disposed adjacent to each other, and a second mass body, which is the other of the two mass bodies, move with respect to the support member so as to approach each other, the first mass body and the second mass body overlap each other as seen from an axial direction of the rotary element.

  • Patent number: 8891100
    Abstract: A clearing section includes a counter for measuring a period up to the reset of contents set by means of an operation panel to initial values. If a position discriminating section discriminates that the operation panel is at a first position, the clearing section starts measuring the period by means of the counter from the first entry made to the operation panel. When a count value reaches a predetermined value, the clearing section executes an automatic clear processing to reset the contents set by means of the operation panel to the initial values. On the other hand, the clearing section cancels the execution of the automatic clear processing if the position discriminating section discriminates that the operation panel is at a second position.

  • Patent number: 8494456
    Abstract: The transmitter of the transceiver includes: a transmitter-side mixers of a transmitter-side modulator; a transmitter-side voltage-controlled oscillator; and a transmitter-side divider. The divider having a dividing factor of a non-integral number is supplied with an oscillating output of the oscillator. A pair of non-quadrature local signals having a phase difference of 90° plus a predetermined offset angle is produced by the divider and supplied to the mixers. The transmitter includes a phase-shift unit which converts a pair of quadrature transmit signals having a phase difference of about 90° on an analog basis into a pair of non-quadrature shifted transmit signals. Consequently, quadrature modulation is performed by the mixers. Use of a similar configuration enables the reduction in interference of an RF signal with local signals supplied to receiver-side mixers of the receiver.

  • Patent number: 8442461
    Abstract: The transmitter synthesizes amplitude and phase components and calibrates a delay mismatch between amplitude and phase components with high accuracy at high speed. The transmitter has: a digital-to-analog converter (DAC) and a low-pass filter (LPF) in its amplitude-signal path; and a phase modulator operable to convert up a phase component into an RF component in its phase-signal path. In an operation of delay calibration, a test input signal is supplied to a delay-calibrating unit in the amplitude-signal path, and the delay-calibrating unit provides a test input signal to DAC. Then, LPF generates a test output signal. The delay-calibrating unit detects a delay of the test output signal relative to the test input signal, calibrates an amplitude signal delay in a range from the input of the delay-calibrating unit to the output of LPF, reduces the difference between amplitude and phase signal delays of the phase modulator in the phase-signal path.
