Publication number: 20240048500Abstract: An Internet Protocol (IP) phone system includes a traffic control device connected to a line. The traffic control device acquires a call duration of each of calls on one line shared by a plurality of IP phones, and sets a packet discard rate of each of the calls in a manner where the packet discard rate is proportional to the call duration until start of a new call so that total call traffic falls within a line capacity of the one line when the total call traffic exceeds the line capacity with the start of the new call.Type: ApplicationFiled: December 23, 2020Publication date: February 8, 2024Applicant: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Fumiaki NAGASE, Masafumi YOSHIOKA, Toshifumi MIYAGI

Publication number: 20230370380Abstract: A congestion control method in an IP telephone system includes acquiring a number of simultaneous calls in one line shared by a plurality of IP telephones, acquiring a call time order corresponding to length of a call time for each call, and controlling a packet discard rate of each call on the basis of the number of simultaneous calls and the call time order. The packet discard rate of each call is set to a predetermined first upper limit value or less. In addition, the packet discard rate is set higher as the call time is longer, and the packet discard rate is set lower as the call time is shorter. Further, the packet discard rate of the latest call having the shortest call time is set to be equal to or less than a predetermined second upper limit value lower than the predetermined first upper limit value.Type: ApplicationFiled: October 8, 2020Publication date: November 16, 2023Inventors: Fumiaki NAGASE, Yu ONO, Keita KURIYAMA, Masafumi YOSHIOKA, Toshifumi MIYAGI, Hitoshi HASEGAWA, Kazuo OSAKA, Hayato FUKUZONO, Hiroyuki FURUYA

Publication number: 20230318632Abstract: Provided is a software wireless device capable of continuing communication without being affected by quality deterioration of a wireless line and without discarding of traffic data. The data to be transmitted is duplicated and wirelessly transmitted over a plurality of communication lines having different frequency bands (step 104). The received data received by the communication line having the best line quality is validated. Another frequency band that is different from the frequency band used in the plurality of communication lines and can provide line quality exceeding a determination criteria is searched (step 106). When the quality of the communication line communicating the same data deteriorates (step 108), the communication on that line is switched to the wireless communication on the additional communication line using the other frequency band (step 110).Type: ApplicationFiled: September 8, 2020Publication date: October 5, 2023Applicant: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Toshifumi MIYAGI, Kazuo OSAKA, Hiroyuki FURUYA, Hitoshi HASEGAWA, Hayato FUKUZONO, Fumiaki NAGASE, Yu ONO, Keita KURIYAMA

Publication number: 20230300255Abstract: A congestion control method in an IP telephone system includes processing of acquiring the number of simultaneous calls on one line shared by a plurality of IP telephones, processing of acquiring lengths of call duration of respective calls, and communication parameter setting processing of setting communication parameters that contribute to communication quality of respective calls on the basis of the number of simultaneous calls and the call duration. The call duration of the first call is longer than the call duration of the second call. The communication parameter setting processing includes processing of setting communication parameters such that the communication quality of the first call is worse than the communication quality of the second call in a case where the number of simultaneous calls exceeds a threshold value.Type: ApplicationFiled: November 11, 2020Publication date: September 21, 2023Inventors: Masafumi YOSHIOKA, Fumiaki NAGASE, Toshifumi MIYAGI

Publication number: 20230275839Abstract: To avoid uniform deterioration of the voice quality of all the calls sharing an IP phone line at a time of congestion. The congestion control method in an IP phone system includes a call state acquisition process of acquiring the number of simultaneous call sessions in one line shared by a plurality of IP phones. A congestion control method further includes a packet loss control process of setting a priority ranking to each call session and dynamically controlling packet loss rates of the call sessions in accordance with the number of the simultaneous call sessions and the priority ranking. In the packet loss control process, the packet loss rate is set lower for call sessions ranked higher in priority, and higher for call sessions ranked lower in priority.Type: ApplicationFiled: June 8, 2020Publication date: August 31, 2023Inventors: Fumiaki Nagase, Keita Kuriyama, Yu Ono, Hitoshi Hasegawa, Hayato Fukuzono, Kazuo OSAKA, Hiroyuki Furuya, Masafumi YOSHIOKA, Toshifumi MIYAGI, Takafumi HAYASHI

Patent number: 5221340Abstract: In a method for producing an odor-free metallic pigment composition, a metallic pigment is ground by a wet process. The pigment is then mixed into a molten thermoplastic resin to vaporize any additives in the metallic pigment by the heat of the resin. The pigment may be dried until its solid content becomes 50-99 percent by weight before mixing into the molten thermoplastic resin.Type: GrantFiled: May 30, 1991Date of Patent: June 22, 1993Assignee: Toyo Aluminum Kabushiki KaishaInventors: Fumiaki Nagase, Masakatsu Harada, Takashi Ohkuma, Yasufumi Uemura, Hideji Murabayashi, Hiroo Usami

Patent number: 4868033Abstract: Laminates comprising a film of heat-shrinkable synthetic resin and a metallic foil or metallized plastic film laminated to the resin film through a bonding layer which comprises a discontinuous layer of a synthetic resin which flows at a temperature for heat shrinkage and an adhesive layer which maintains its adhesive strength at that temperature. Upon heat shrinkage, the metallic foil or metallized plastic film will wrinkle at the portions in contact with the synthetic resin which is not highly adhesive at the temperature for heat shrinkage. The heat-shrunk laminate can be formed into a casing or container such as an electromagnetic interference shield, a packaging material, and decorative material.Type: GrantFiled: July 1, 1988Date of Patent: September 19, 1989Assignee: Toyo Aluminum Kabushiki KaishaInventors: Toshihiko Nakano, Fumiaki Nagase, Eiichi Takeuchi, Mamoru Kamada, Hideyo Shigematsu
