  • Patent number: 10569173
    Abstract: In an example of a system, in a virtual space, a player camera that follows each player in a multiplay game, a bird's-eye camera that views the virtual space from a bird's-eye view, and an object camera that follows a predetermined object are set. A watcher watches the game by switching the player camera, the bird's-eye camera, and the object camera. In accordance with an operation of the watcher, the bird's-eye camera moves in the virtual space, and a height of the bird's-eye camera is determined in advance in accordance with a position. When virtual cameras are switched by the watcher, a game image from the virtual cameras during the switching is displayed.

  • Publication number: 20190170376
    Abstract: [Problem to be Solved] To provide a gas humidity regulating method and a regulator that can regulate a temperature during humidity control and improve humidity-control efficiency. In an air humidity regulating method for gas subjected to treatment, a first medium 22 is caused to flow onto a heat exchanging pipe 17 of a gas-liquid contact part 18 in a dehumidifier 11; meanwhile, a second medium 24 is passed through the heat exchanging pipe 17. In this state, air is fed into a gas-liquid contact case 13 from an inlet port 14 and gas-liquid contact is made by the first medium 22 on the gas-liquid contact part 18 so as to absorb water content from the air into the first medium 22. The first medium 22 contains an ionic liquid having high absorbency. The temperature of the first medium 22 is regulated by the second medium 24. After that, treated air is discharged from an outlet port 15 of the gas-liquid contact case 13.

    Abstract: A first control unit reads out both specific frequencies and gain data corresponding to these specific frequencies, which have been stored into a first storage unit, and approximates gain data corresponding to an arbitrary frequency by way of a linear function to calculate the gain data by executing a formula. A D/A converter converts this gain data into a gain control signal, and supplies the gain control signal to a variable gain amplifier. The variable gain amplifier amplifies a transmission signal by a gain defined in response to a transmission frequency based upon the gain control signal.

The radio communication apparatus includes a fixed-gain IF amplifier and a variable-gain IF amplifier. One is selected out of the fixed-gain IF amplifier and the variable-gain IF amplifier as an effectively used IF amplifier in response to which of the radio communication formats is selected. The fixed-gain IF amplifier is selected as an effectively used IF amplifier when a narrow-band radio communication format is selected. The variable-gain IF amplifier is selected as an effectively used IF amplifier when a wide-band radio communication format is selected.

  • Patent number: 6032032
    Abstract: A radio communication apparatus is designed for at least first and second radio communication formats which prescribe first and second desired IF pass bandwidths respectively. The first desired IF pass bandwidth is greater than the second desired IF pass bandwidth. The radio communication apparatus includes an IF band-pass filter processing a first IF signal into a second IF signal and having a predetermined pass bandwidth corresponding to the first desired IF pass bandwidth. A demodulator recovers a first baseband signal from the second IF signal generated by the IF band-pass filter. A baseband filter processes the first baseband signal generated by the demodulator into a second baseband signal. The first baseband signal generated by the demodulator is selected as a final output signal when the first IF signal is of the first radio communication format.

  • Patent number: 5966666
    Abstract: A frequency synthesizer consists of a voltage-controlled oscillator and a frequency division and distribution section. The frequency division and distribution section, which splits an oscillation signal of the voltage-controlled oscillator into a transmission modulation local oscillation signal and a reception second local oscillation signal while frequency-dividing the oscillation signal of the voltage-controlled oscillator, includes two pairs of frequency dividers and two switches. The frequency division numbers of the two pairs of frequency dividers are so set as to accommodate all the combinations of mobile communications systems and the transmission modulation local oscillation signal/reception second local oscillation signal. The two switches are switched in accordance with a mobile communications system for which a mobile transceiver is operating. The two local oscillation signals are input to a quadrature modulator and a quadrature demodulator, respectively.
