Patent number: 9702980Abstract: A method for reducing the positioning time of a GPS receiver is disclosed. In response to a request from a user function for positioning data, a GPS management section instructs a device control section to lower the functions of a group of components. The lowering of the functions of the components reduces the noise level. The GPS management section operates the GPS receiver. The GPS receiver executes an acquisition process in an environment with a low noise level. After completion of the acquisition process, the functions of the component are restored.Type: GrantFiled: October 3, 2014Date of Patent: July 11, 2017Assignee: LENOVO (SINGAPORE) PTE LTDInventors: Yoshi Nishioka, Takafumi Onodera, Masahide Tamura

Patent number: 4633511Abstract: A duplex transmission and reception system wherein a local oscillator of the receiver is dispensed with by using the output of a modulated transmission oscillator, with its modulation cancelled, in lieu of a receiver local oscillator. The transmitter modulation signal is adjusted by appropriate level correction and phase inversion. The modulated output of the transmission oscillator is itself applied to a modulator, where it is modulated by the adjusted modulation signal. This results in substantially cancelling out the modulation component of the transmission oscillator output. This modulation-cancelled signal is supplied to the mixer of a superheterodyne receiver as a local oscillator signal.Type: GrantFiled: August 23, 1984Date of Patent: December 30, 1986Assignee: Toyo Communication Equipment Co.Inventors: Daisuke Koga, Masahide Tamura, Yukio Naito

Patent number: 4477786Abstract: A semi-coaxial cavity resonator filter including a plurality of semi-axial cavity resonators, as constructed units, each of which has an adjustable device in which dielectric substrates having a specific dielectric constant of more than 1 are disposed in the gap between the inside wall of a tube-shaped outer conductor and the open end of an inner conductor provided on the inside wall of the outer conductor, and the electrostatic capacitance of the spaces interposed by the dielectric substrates is changed without steps by varying the area of the electrodes on the dielectric substrate. The filter is made by making an individual and predetermined frequency adjustment on the plurality of the semi-axial cavity resonators and then cascade-connecting those resonators in one block through shielding plates having a coupling iris so as to obtain desired filtering characteristics as a bandpass filter.Type: GrantFiled: September 27, 1982Date of Patent: October 16, 1984Assignee: Toyo Communication Equipment Co., Ltd.Inventors: Masahide Tamura, Koga Daisuke

Patent number: 4395776Abstract: A transmitter having a transmitting phase synchronizing system. To one input of a frequency mixer is applied the output of a phase synchronizing type digital frequency synthesizer, through a first frequency divider. A modulating signal is applied to another input of the frequency mixer. The output from the mixer is connected via a bandpass filter to a phase synchronizing system having in series, along a main route, a phase detector, a lowpass filter, and a voltage controlled oscillator, and thence to an amplifier system. In a feedback route from another outlet of the voltage controlled oscillator to the phase detector is a second fixed frequency divider. The digital frequency synthesizer itself may have a reference oscillator connected in series to a third fixed frequency divider, a second phase detector, a second lowpass filter and a second voltage controlled oscillator, from which a feedback circuit leads back to the phase detector via the first fixed frequency divider and a variable frequency divider.Type: GrantFiled: May 27, 1981Date of Patent: July 26, 1983Assignee: Toyo Communication Equipment Co., Ltd.Inventors: Yukio Naito, Masahide Tamura, Shigeo Takahashi
