Patent number: 11979021Abstract: A power converter for a power system performs power control of a power system by using a first control value derived based on a first stabilization command value for causing a voltage on a first DC bus to be within a first range and a first control command value different from the first stabilization command value. A power converter for a solar cell performs power control of a solar cell by using a second control value derived based on a second stabilization command value for causing a voltage on a second DC bus to be within a second range and a second control command value different from the second stabilization command value. The first range is narrower than the second range.Type: GrantFiled: January 22, 2020Date of Patent: May 7, 2024Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Akira Yoshitake, Tomomi Kato, Takuya Karikawa, Yoshinori Noritake

Patent number: 6259768Abstract: A method employs simple procedures to speedily carry out loopback tests on devices that form a channel system of an exchange. The method is capable of quickly locating a fault in the exchange and allowing speedy maintenance work of the exchange. Also provided is an apparatus for achieving the method. The apparatus has a path setter (1-4), a loopback controller (1-3), and a tester (1-1), to test the devices of the channel system (1-2) of the exchange. The devices to be tested are arranged in replaceable units (1-21, 1-22). The path setter (1-4) simultaneously sets paths to sequentially connect the devices to be tested. The loopback controller (1-3) activates and releases loopback parts arranged in the devices to be tested. The tester (1-1) sends a test signal to the devices through the paths, receives the test signal looped back by the loopback parts, analyzes the received signal, and determines whether or not the devices are sound.Type: GrantFiled: February 1, 1999Date of Patent: July 10, 2001Assignee: Fujitsu LimitedInventors: Tomomi Kato, Masatoshi Takita, Kazuei Ohnishi, Takamitsu Saito, Kosei Mano

Patent number: 3937422Abstract: A brake mechanism in a magnetic tape recording and reproducing machine in which a magnetic tape is transported from one reel to the other reel comprising brake drums corresponding to two reels, brake shoes, means for securing the brake shoes and means for pressing the brake shoes to respective brake drums. Two micro-switches are provided for detecting the displacement of the respective means for securing the brake shoes in the direction of the rotation of the respective brake drums caused by the friction between the brake shoes and the brake drums in the operation of the brake mechanism.The two micro-switches are used for controlling a circuit giving D.C. current to stator windings of two electric motors for driving respective reels so that the rotors of both motors may be subjected to electromagnetical braking. The two micro-switches are also used for prohibiting the machine from starting until the tape transportation is perfectly stopped after operation of the brake mechanism.Type: GrantFiled: November 30, 1973Date of Patent: February 10, 1976Assignee: Sansui Electric Co., Ltd.Inventor: Tomomi Kato
