Publication number: 20230318645Abstract: A wireless communication device comprises a first communication unit, a second communication unit and a single control unit. The first communication unit wirelessly communicates by a first communication signal according to a first communication standard. The second communication unit wirelessly communicates by a second communication signal according to a second communication standard. The second communication signal has a frequency band that overlaps with that of the first communication signal. The second communication standard is different from the first communication standard.Type: ApplicationFiled: June 5, 2023Publication date: October 5, 2023Inventor: Yasuo ICHIMURA

Patent number: 7307410Abstract: The AC detection coil is a toroidal coil and includes plural radial-line conductors which are formed on a front face and a rear face of a substrate, conductive connection parts and conductive through-holes which connect electrically each end of radial-line conductors, wherein plural winding turns are consecutively formed by a connection of each radial-line conductor on the front and the rear faces, respectively, and include a forward coil and a backward coil, and each shape on the front and the rear faces of the radial-line conductors and the conductive connection parts are identical with each other. Consequently, when seen from a thickness direction of the substrate, areas of the forward coil and the backward coil are equal to each other, and an external, unneeded to be detected, magnetic field can be canceled each other by the forward coil and the backward coil, then a current detection accuracy can be improved.Type: GrantFiled: November 21, 2006Date of Patent: December 11, 2007Assignee: Matsushita Electric Works, Ltd.Inventors: Akimi Shiokawa, Eiji Iwami, Yasuo Ichimura, Akihiro Ishibashi, Kazunari Yoshimura

Publication number: 20070152651Abstract: The alternating current detection coil is a toroidal coil, and comprises plural radial-line conductors which are formed on a front face and a rear face of a substrate, conductive connection parts and conductive through-holes which connect electrically each end of radial-line conductors, wherein plural winding turns are consecutively formed by a connection of each radial-line conductor on the front face and the rear face respectively, the winding turns comprise a forward coil and a backward coil, and each shape on the front face and the rear face of the radial-line conductors and the conductive connection parts are identical with each other. Consequently, when seen from a thickness direction of the substrate, areas of the forward coil and the backward coil are equal to each other, and an external magnetic field, which does not need to be detected, can be canceled each other by the forward coil and the backward coil, then a current detection accuracy can be improved.Type: ApplicationFiled: November 21, 2006Publication date: July 5, 2007Applicant: MATSUSHITA ELECTRIC WORKS, LTD.Inventors: Akimi Shiokawa, Eiji Iwami, Yasuo Ichimura, Akihiro Ishibashi, Kazunari Yoshimura

Patent number: 4947146Abstract: An electromagnetic contactor is formed by disposing an inner yoke to oppose at an end to a pole-contacting member provided at an end of an armature in an electromagnet block, disposing the outer yoke to oppose at an end to the said end of the inner yoke so as to restrict the displacement of the pole-contacting member and at the other end to a plunger part of the armature perpendicularly and closely thereto, and inserting a magnetic cylinder into an axial through hole of a coil bobbin of the electromagnet block for passing therethrough the plunger part from the side of the said other end of the outer yoke, whereby any leak of magnetic flux due to coil excitation and that of a permanent magnet disposed between the both yokes can be restrained to be the minimum and a highly efficient operation of the contactor can be realized.Type: GrantFiled: March 8, 1989Date of Patent: August 7, 1990Assignees: Matsushita Electric Works, Ltd., Klockner-Moeller Elektrizitats-GmbHInventors: Yasuo Ichimura, Hidetoshi Matsushita, Kenji Kawasaki, Youichi Aoyama

Patent number: 4523164Abstract: A circuit breaker capable of breaking an associated circuit when an overcurrent higher than a rated current keeps flowing through the breaker or upon a short-circuit current. Electric power path in the breaker is partly inserted through an arm of a magnetic material and holding a movable contactor plate of make-and-break contact means, an armature means is provided as pivoted at one end to the holding arm, and a tension spring means is provided between the other end of the armature means and the movable contactor plate to provide a contact pressure. The overcurrent flowing through the path causes a magnetic force to be induced in the holding arm, whereby the armature means is rotated to change the direction in which the force of the tension spring means acts on the movable contactor plate and the latter breaks the contact means.Type: GrantFiled: July 26, 1984Date of Patent: June 11, 1985Assignee: Matsushita Electric Works, Ltd.Inventors: Youichi Aoyama, Akira Takeuchi, Masaru Ohmuro, Yasuo Ichimura
