Publication number: 20240136925Abstract: A circuit board of a switching power supply device includes a positive terminal circuit pattern and a negative terminal circuit pattern that are provided on a component mount surface and respectively supply currents from input parts to two input terminals of a common mode choke coil. The positive terminal circuit pattern and the negative terminal circuit pattern are positioned in parallel and close to each other. The component mount surface of the circuit board includes a component mount surface side ground pattern arranged below the common mode choke coil. A heat dissipation ground surface of the circuit board includes a ground pattern and a plurality of heat dissipation conductor patterns. Input terminals and output terminals of the common mode choke coil are respectively electrically and thermally connected to the heat dissipation conductor patterns via through-hole conductors provided between the component mount surface and the heat dissipation ground surface.Type: ApplicationFiled: December 28, 2023Publication date: April 25, 2024Applicant: Murata Manufacturing Co., Ltd.Inventors: Yuki ISHIKURA, Tatsuya HOSOTANI, Hiroyuki TAKATSUJI

Publication number: 20240136926Abstract: A noise reduction circuit includes a surface-mount common mode choke coil mounted on a circuit board. Output terminals of the common mode choke coil are connected to an input capacitor via second circuit patterns. Two terminals of the input capacitor are connected to two input ends of a switching circuit via third circuit patterns. Path lengths of the second circuit patterns are longer than path lengths of the third circuit patterns. Of a plurality of current paths, the path lengths of the third circuit patterns are shortest in comparison with path lengths of other current paths. First circuit patterns are parallel and face each other to form a first parasitic capacitance, and the second circuit patterns are parallel and face each other to form second parasitic capacitances.Type: ApplicationFiled: January 3, 2024Publication date: April 25, 2024Applicant: Murata Manufacturing Co., Ltd.Inventors: Tatsuya HOSOTANI, Hiroyuki TAKATSUJI, Yuki ISHIKURA

Patent number: 11909936Abstract: An image forming apparatus records identification information of an external memory and identification information of a scan job as a log when the external memory is attached to start the scan job. When the external memory is removed in the middle of the scan job, scan data is temporarily saved together with the identification information of the job. When the removed external memory is attached, for example, in a ready state, log data is referred to determine whether the external memory is that removed in the middle of the job and whether the scan data associated with the external memory is saved. When it is determined that the scan data is saved, the scan data is saved in the external memory.Type: GrantFiled: March 3, 2023Date of Patent: February 20, 2024Assignee: SHARP KABUSHIKI KAISHAInventor: Hiroyuki Ishikura

Patent number: 10965829Abstract: An image forming apparatus is provided with USB sockets on front and back sides, and includes a determining unit for determining whether or not a USB device inserted to a front side USB socket is a function enhancement device, and a control unit making, when it is determined by the determining unit that a function enhancement device is inserted to the front side USB socket, the USB device unusable and making, when it is determined that a USB device other than the function enhancement device is inserted, the USB device usable. Thus, it is possible to prevent a USB wireless LAN adapter or the like from being used constantly connected to the front side USB socket and thereby to reduce possibility of USB wireless LAN adapter of being damaged or removed.Type: GrantFiled: April 24, 2019Date of Patent: March 30, 2021Assignee: SHARP KABUSHIKI KAISHAInventor: Hiroyuki Ishikura

Patent number: 10474088Abstract: An image formation device includes a power controller that controls transition to an energy-saving mode to reduce power consumption in a standby state and starts up out of the energy-saving mode and a timer in which a timing schedule that starts up the device out of the energy-saving mode is set. The power controller controls the surface temperature of the fixing roller of the image generator to be a temperature lower than the fixing temperature that enables image formation when the image formation device is started up out of the energy-saving mode according to the timing schedule set in the timer.Type: GrantFiled: January 9, 2019Date of Patent: November 12, 2019Assignee: SHARP KABUSHIKI KAISHAInventor: Hiroyuki Ishikura
