  • Patent number: 7993423
    Abstract: A grease filter has a filtering portion configured such that fumes enter a major face thereof and flow through a grease extraction filter therewithin in a direction parallel to the major face. A frame that fits into an opening of a hood defines a box structure that is configured to allow flow from the end (or ends) of the filtering portion where flow exits. The frame permits the flow to exit to a side opposite the face even when the frame is surrounded, edgewise, by a solid structure of the hood opening.

  • Patent number: 7995982
    Abstract: The present invention aims to efficiently calibrate the characteristics of a pair of reception or transmission low-pass filters by a receiving or transmitting circuit. A semiconductor integrated circuit includes an RF receiver that processes an RF reception signal, an RF transmitter that generates an RF transmission signal and a frequency synthesizer. A reception low-pass filter of the RF receiver suppresses undesired components contained in I and Q baseband reception signals. A transmission low-pass filter of the RF transmitter suppresses noise due to D/A conversion, which is contained in I and Q transmission analog baseband signals. A calibration test signal is supplied to the inputs of the pair of reception or transmission low-pass filters. A difference in phase between the pair of filters is detected by a phase detection unit. A calibration controller calibrates a relative mismatch between the cut-off frequencies of the pair of filters.

  • Patent number: 7994825
    Abstract: In an output circuit having a de-emphasis for use in high-speed serial transmission, a circuit for suppressing a fluctuation of a common mode potential which occurs in output amplitude is provided. A positive pole and a negative pole of an output circuit in a serial transmission device for differential transmission having de-emphasis are connected to the respective outputs of a differential circuit that differentially receives outputs of a detector device for a pattern of data to be transmitted, and a detector device for an inverted pattern of the data to be transmitted. When a specific pattern of data to be transmitted and its reverted pattern appear, a current of the output circuit is compensated by the connected differential circuit, thereby enabling a common mode noise to be prevented.

  • Patent number: 7994822
    Abstract: The performance of a whole system is improved by synchronizing communication and computations between stacked computing LSIs. Each of stacked an external communication LSI and a computing LSI has a PLL which multiplies a crystal oscillator clock signal, a clock pulse generator which distributes the clock signal, and flip-flop circuits. The computing LSI has a DLL circuit composed of a clock phase comparator, a delay controller, and a delay chain. In order to synchronize the communication and computations of the external communication LSI and the computing LSI, a synchronization reference clock signal is transmitted from the external communication LSI to the computing LSI via a through-electrode. An internal clock signal of the computing LSI is synchronized with the synchronization reference clock signal from the external communication LSI by the DLL circuit.

  • Patent number: 7996003
    Abstract: When generating an RF test signal for mismatch calibration for receiver in order to calibrate reception mismatch of an I-phase signal and a Q-phase signal that are output from demodulated signal processing circuits coupled to mixers for receiving, a Tx VCO avoids covering the higher frequency of an RF received signal in an FDD system. An RF test signal generating unit generates, in a calibration mode of a mismatch calibration for receiver circuit, the RF test signal by using an oscillation output signal of the Tx VCO and other circuits, and supplies the same to the mixers for receiving via a switch. The RF test signal has a frequency within an RF reception frequency band that is higher than that of an RF transmission signal with the maximum frequency band of multiband radio frequency communications. By switching the switch in a reception mode, an output of a low-noise amplifier that amplifies the RF received signal received by an antenna is supplied to each of the mixers for receiving.
