Publication number: 20240072398Abstract: Unintentional damage of a power supply device during assembling of the device is avoided to increase workability of the assembling. The power supply device includes secondary battery cells each including an electrode terminal, a battery holder holding the cells, and a circuit board including a control circuit mounted thereon and electrically connected to the cells to control charging and discharging. A method of manufacturing the device includes connecting, to a board-side ground terminal disposed on the board, a battery-side ground terminal drawn outside from the holder as a ground of a total output of the cells electrically connected in series and/or parallel, mounting the board on a surface of the holder, and connecting, to respective one or more board-side intermediate terminals disposed on the board, one or more battery-side intermediate terminals disposed on the holder being electrically connected to at least one of the cells.Type: ApplicationFiled: January 20, 2022Publication date: February 29, 2024Inventors: NAOKI KAWAI, TAKAHIRO YAMASHITA, TOMOYUKI ICHIZA

Publication number: 20150362801Abstract: Provided is a flat-panel display for improving a structure of a shape of a through-hole of a backlight cover that is a resin-made member, which is passed through when making a PWB contact a metal plate member, so that a gasket can be mechanically fixed. This flat-panel display includes: a metal plate member (30) arranged on a rear side of a display panel; a non-conductive plate member (20) arranged so as to face a rear side of the metal plate member (30) and including a through-hole (42); a circuit board (50) arranged so as to face a rear side of the non-conductive plate member (20) ; and a gasket (90) arranged in the through-hole (42) and holding conduction of the metal plate member (30) and the circuit board (50), in which the non-conductive plate member (20) includes a gasket fixation portion (44) formed around the through-hole (42) in a convex shape.Type: ApplicationFiled: February 13, 2014Publication date: December 17, 2015Applicant: SHARP KABUSHIKI KAISHAInventors: Tomoyuki ICHIZA, Naoki FUKUDA, Sunao OHNISHI, Akihisa KANEKO, Junya YOSHINO, Toshiyuki KATOH

Patent number: 9204507Abstract: This LED lighting device makes a maximum current to minimum current flowing in an LED a target proportion regardless of LED driving circuit performance and without erroneous operation. An LED lighting device (1) is provided with: an LED circuit (5) that includes at least one LED (1-5); a bypass means (6a) inserted in parallel with the LEDs (1-5); and an LED driving circuit (4) that supplies current by duty control to the LEDs (1-5) and the bypass means (6a). When a prescribed minimum current flows in the LED circuit (5), the LED driving circuit (4) supplies current in which a portion of current flowing in the bypass means (6a) is added to this minimum current and carries out control of the added current by a switching element (TR1) connected in series to the LED circuit (5) and the bypass means (6a).Type: GrantFiled: September 21, 2012Date of Patent: December 1, 2015Assignee: SHARP KABUSHIKI KAISHAInventors: Shogo Fukuda, Tomoyuki Ichiza, Toshimasa Ogawa
