Publication number: 20240171013Abstract: To provide a specific method that is feasible and effective for performing MCPT control with a relatively simple configuration. A power-receiving device for receiving electric power transmitted from a power-transmitting device, based on a wireless power transfer method is provided. The power-receiving device includes: a power-receiving antenna for receiving electromagnetic waves; a rectifier functionally connected to the power-receiving antenna for converting the electromagnetic waves into DC voltages; a controller functionally connected to the rectifier for adjusting a resistance on an output side of the rectifier; and a power storage device for storing an output of the controller. Voltage-current characteristics of the rectifier vary according to a distance between the power-transmitting device and the power-receiving device.Type: ApplicationFiled: March 31, 2021Publication date: May 23, 2024Inventors: Naoto KODATE, Yuji TANABE

Publication number: 20240097489Abstract: A device housing is provided for wirelessly receiving electric power in order to supply electric power to a device with an excellent power-receiving efficiency, while suppressing an increase in its size as a whole. Also, a device having the same device housing and a device housing for constituting a main body of a device which is a sensor or an actuator are provided. The device housing is provided with a power-receiving device for mainly generating an electric field or a magnetic field for performing wireless power supply. The power-receiving device includes at least one of a dipole antenna, a slot antenna, a monopole antenna, a chip antenna and an inverted-F antenna. The device housing has a size in a three-dimensional space, and expansion of its size in the three-dimensional space due to the provision of the power-receiving devices is substantially limited to one axis direction (X-axis direction) at most.Type: ApplicationFiled: March 31, 2021Publication date: March 21, 2024Inventors: Yuji TANABE, Naoto KODATE

Patent number: 5991449Abstract: An image memory outputs a target encoding pixel and a plurality of reference pixels in the vicinity thereof. A boundary mode determining unit determines a maximum value and a minimum value of the reference pixels, determines an average value of the maximum value and the minimum value, compares the respective reference pixel values with the average value, detects a boundary in the target encoding pixel and the reference pixels based on comparison results, and detects a pixel distribution state of the reference pixels based on the detected boundary. An adaptive predictor calculates a prediction value by performing a calculation based on a function corresponding to the pixel distribution state and the reference pixels. A prediction difference calculating unit determines a difference value between the prediction value and a value of the target encoding pixel.Type: GrantFiled: July 15, 1996Date of Patent: November 23, 1999Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Tomohiro Kimura, Ikuro Ueno, Taichi Yanagiya, Masayuki Yoshida, Fumitaka Ono, Naoto Tanabe

Patent number: 5918156Abstract: A satellite communication system broadcasts an information signal from a transmitting station to a plurality of receiving stations via a communication satellite. An answer station is provided among a plurality of receiving stations which are located in a predetermined geographical area. The answer station and the plurality of receiving stations in the designated group are connected by a ground data link. The answer station collects status data of each of the receiving stations to transmit an answer signal to the transmitting station on behalf of the group of receiving stations, so that a transmitting function for each of the receiving stations can be eliminated. The answer station can also act as one of the receiving stations in the designated group.Type: GrantFiled: February 28, 1997Date of Patent: June 29, 1999Assignee: Fujitsu LimitedInventor: Naoto Tanabe

Patent number: 4471162Abstract: A coordinate reading apparatus for reading positions on a tablet, having magnetic-field generating coils, with a magnetic-field detector. The magnetic-field detector produces an analog electric signal corresponding to a desired position to be read on the tablet in response to the magnetic fields induced by the magnetic-field generating coils. The analog electric signal generated by the detector is composed of both a fundamental wave component signal and an n-th order harmonic wave component signal (n being an integer equal to or larger than 2). A processing unit for receiving the analog electric signal from the magnetic-field detector and produces coordinate data corresponding to the desired position to beread on the tablet by analyzing a first rotating magnetic-field vector induced by the fundamental wave component signal and a second rotating magnetic-field vector induced by the n-th order harmonic wave component signal.Type: GrantFiled: December 28, 1982Date of Patent: September 11, 1984Assignee: Fujitsu LimitedInventors: Yoshihito Aono, Yukio Takeda, Naoto Tanabe

Patent number: 4204011Abstract: A method of driving or permeating a powdery material into a porous material such as an open-cell cellular material or a fabric, of a type having an open-celled structure, that is, having interconnected cells. Permeation of the powdery material into the porous material is carried out by spreading a mass of powdery particles on one surface of the porous material and applying vibrations to the powdery particles through a vibrating element in contact with the particles so as to cause the particles to be uniformly distributed in the porous material. The frequency and amplitude of the vibrations are selected so as to minimize scattering of the powdery material, and are within the ranges of 50 to 50,000 Hz, and 50 to 1,500 .mu.m, respectively.Type: GrantFiled: June 30, 1978Date of Patent: May 20, 1980Assignee: Kurashiki Boseki Kabushiki KaishaInventors: Naoto Tanabe, Kenzoh Okada, Norio Maeda
