  • Patent number: 7873310
    Abstract: An oblique movement preventing device for an endless belt, the inner surface of the belt supported by rollers, and at least one roller circulating the belt on the rollers, includes a contact angle changing unit. The changing unit selectively presses either side part of the outer surface of the belt at a position near to the one roller on an upstream side of the one roller in the predetermined belt circulating direction, thereby changing a contact angle of the belt on the one roller along the width direction of the belt. A measuring unit measures a direction and distance of displacement of the belt caused by the oblique movement thereof, and a control unit controls the operation of the changing unit to cease the oblique movement of the belt, based on the measured direction and distance of displacement of the belt.

  • Patent number: 7027794
    Abstract: The cutoff frequency is set high in order to prevent suppression of low-frequency components so that high-quality reception control of a radio signal can be realized. A radio signal amplifier unit amplifies a received radio signal and results in an amplified signal. A frequency conversion unit mixes the amplified signal with a local oscillation signal to thereby convert the radio signal having a radio frequency signal into the radio signal having an intermediate frequency signal, resulting in an intermediate frequency signal. A frequency shift control unit shifts the intermediate frequency signal towards the upper part of the frequency band. A frequency inversion unit inverts a low-frequency side of the intermediate frequency signal towards the upper part of the frequency band and inverts a high-frequency side thereof towards a lower part thereof. An AC coupling unit is provided at an output side of the frequency control unit.

  • Patent number: 7028292
    Abstract: In a program executing apparatus, a code reading section reads intermediate codes into a storage unit. A data-reference analyzing section determines whether the operands of instructions in the intermediate codes stored in the storage unit require a data reference. Each data reference is analyzed for instructions requiring the data reference. A code rewriting section rewrites the operands of the instructions according to the analysis information obtained by the data-reference analyzing section. An address updating section updates the addresses of address-related instructions. After all intermediate codes are interpreted, a main interpreting and executing section starts interpreting and executing the intermediate codes.

  • Patent number: 6775317
    Abstract: A transmitter of a base station stops a spread modulation so as to transmit a free-line signal and a call-in signal to a mobile station in a wait state. A receiver of a mobile station which is in the wait state stops a despread modulation so as to receive the free-line signal and the call-in signal which are from the base station. The transmitter modulates, spreads, and then transmits and the receiver receives and then despreads and demodulates a control signal for connecting a line after transmitting and receiving the call-in signal are completed, a control signal for connecting the line when a call-out request is sent from the mobile station, and a talk signal and a talk completion control signal which are transmitted and received through the line.
