Publication number: 20190350676Abstract: A mouthpiece (76) is detachably attached to the maxillary teeth dentition of a patient. A mouthpiece body (78) has an approximately uniform thickness. A mandibular teeth dentition impression (84) in an optimized chewing occlusal jaw position that balances the systemic basal muscle tone of the patient is formed on the occlusal surface of the mouthpiece body (78). When the patient attaches the mouthpiece (76) to the maxillary teeth dentition to achieve a chewing occlusal state or a resting occlusal state, the mandibular teeth dentition is induced to a proper positional relationship that balances a systemic basal muscle tone with respect to the maxillary teeth dentition due to the tongue/jaw position reflex and masseter/jaw position reflex of the patient, caused by attaching the mouthpiece (76), whereby a systemic pain symptom can be resolved or greatly relieved.Type: ApplicationFiled: July 1, 2019Publication date: November 21, 2019Inventor: Hiroaki ARAI

Publication number: 20180054170Abstract: A distortion compensation device includes a distortion compensation unit, a feedback coefficient calculating unit, a clip processing unit, and an updating unit. The distortion compensation unit generates a distortion compensation signal from a transmission signal by using a distortion compensation coefficient and inputs the generated distortion compensation signal to a power amplifier. The feedback coefficient calculating unit calculates a feedback coefficient based on an output signal from the power amplifier. The clip processing unit outputs the feedback coefficient when absolute value of the feedback coefficient is less than a threshold. Furthermore, the clip processing unit outputs a feedback coefficient of which absolute value is less than the threshold when the absolute value of the feedback coefficient is greater than the threshold.Type: ApplicationFiled: August 14, 2017Publication date: February 22, 2018Applicant: FUJITSU LIMITEDInventors: Hiroaki Arai, HIROYOSHI ISHIKAWA, Kazuo Nagatani

Patent number: 9872294Abstract: A base station includes a determining unit, and a change unit. The determining unit determines, for each terminal, whether reception quality of an uplink signal from the terminal is equal to or smaller than a certain threshold. The change unit performs first processing or second processing when the reception quality is equal to or smaller than the certain threshold. The first processing is the processing of instructing a first terminal, a terminal of a transmission source of an uplink signal, to change the frequency of the uplink signal of the first terminal to the frequency of either an uplink or a downlink signal assigned to each terminal. The second processing is the processing of changing the frequency of a downlink signal identical to that of the uplink signal from the first terminal to the frequency of either an uplink or a downlink signal assigned to each terminal.Type: GrantFiled: March 23, 2016Date of Patent: January 16, 2018Assignee: FUJITSU LIMITEDInventors: Hiroaki Arai, Tsuyoshi Hasegawa, Tokuro Kubo
