Patent number: 11942685Abstract: A first antenna, a second antenna, and a waveguide structure are housed in a single cabinet. An operating frequency of the second antenna is higher than an operating frequency of the first antenna. The second antenna is an array antenna including a plurality of radiating elements. The waveguide structure is present outside a range of a half-value angle of a main beam as viewed from the first antenna, includes a unit waveguide disposed in a route of a radio wave received by the second antenna, and further attenuates a radio wave with the operating frequency of the first antenna.Type: GrantFiled: February 17, 2022Date of Patent: March 26, 2024Assignee: MURATA MANUFACTURING CO., LTD.Inventors: Hideki Ueda, Yasuhisa Yamamoto, Masashi Omuro, Kazunari Kawahata, Satoshi Tanaka, Ryuken Mizunuma

Patent number: 11611361Abstract: A feed line connects an RFIC and a radiating element. A baseband ground plane (BB ground) is connected to a ground terminal of a BBIC. A radio frequency ground plane (RF ground) is placed in such a manner as to overlap the BB ground. The RF ground serves as a return path of the feed line. A first inter-ground connection circuit connects the BB ground and the RF ground. Furthermore, a second inter-ground connection circuit connects the BB ground and the RF ground. Connecting parts between these grounds and the second inter-ground connection circuit are arranged closer to the edges of these grounds than connecting parts between these grounds and the first inter-ground connection circuit. The connecting part between the ground and the second inter-ground connection circuit is placed on one side of a certain imaginary straight line that passes substantially the geometric center of the ground.Type: GrantFiled: September 25, 2020Date of Patent: March 21, 2023Assignee: MURATA MANUFACTURING CO., LTD.Inventors: Kazunari Kawahata, Ryuken Mizunuma, Hideki Ueda, Satoshi Tanaka, Masashi Omuro, Yasuhisa Yamamoto

Patent number: 11050448Abstract: A receiver device includes an antenna that receives a high frequency signal having a bandwidth, a mixer connected to the antenna and a frequency multiplier. A filter that removes a noise signal whose frequency is different from that of the local signal is provided between the local oscillator and the frequency multiplier. The filter removes the noise signal that satisfies the condition that the absolute value of the frequency difference between the center frequency of the local signal and the center frequency of the noise signal is less than the bandwidth of the high frequency signal.Type: GrantFiled: May 28, 2020Date of Patent: June 29, 2021Assignee: Murata Manufacturing Co., Ltd.Inventors: Kenichi Ito, Masashi Omuro, Yu Ishiwata

Patent number: 10630335Abstract: A signal transmission and reception element transmits and receives a differential signal. Two transmission lines transmit the differential signal between the signal transmission and reception element and a connector. The signal transmission and reception element is connected to an external apparatus with the connector interposed therebetween. A noise generation source generates noise in a wireless band, which is coupled to the transmission lines. An antenna has a gain in a frequency band of the noise which is generated in the noise generation source. A wireless signal processing circuit processes a signal received by the antenna. An absorption-type filter that is mounted on the transmission lines absorbs noise mixed in the transmission lines.Type: GrantFiled: October 20, 2017Date of Patent: April 21, 2020Assignee: Murata Manufacturing Co., Ltd.Inventors: Kota Saito, Yoshihiro Imanishi, Hiroshi Kitada, Hiroyuki Takatsuji, Masashi Omuro

Patent number: 5675789Abstract: A file compression processor of the present invention comprises a file status monitor which compares the current available capacity on the file unit to record files and the threshold value predetermined as the upper limit of the available capacity and a file compression portion which compresses a file on said file unit when the file status monitor judges that the current available capacity is smaller than the threshold.Type: GrantFiled: June 26, 1996Date of Patent: October 7, 1997Assignee: NEC CorporationInventors: Masanori Ishii, Masashi Omuro

Patent number: 5479615Abstract: In a buffer asynchronous output apparatus comprising a plurality of renewal processing programs each of which renews one of buffer areas in a system shared buffer unit as a renewed buffer area, a copied buffer area securing section secures a copied buffer area. A renewed buffer area copying section copies contents of the renewed buffer area into the copied buffer area. An output request enqueuing section enqueues an output request into an output request waiting queue. Performed asynchronously with the renewal processing programs, an output processing program comprises a file outputting section for outputting contents of the copied buffer area into a file device on reception of the output request dequeued from the output request waiting queue. After completion of a file output processing by means of the file outputting section, an output completion informing section stores an output completion status and a file output result status in a copied buffer information field on a buffer control table.Type: GrantFiled: December 8, 1992Date of Patent: December 26, 1995Assignee: NEC CorporationInventors: Masanori Ishii, Masashi Omuro
