Publication number: 20240057979Abstract: Behind an electronic circuit, an auxiliary backing having a first thermal anisotropic property is provided. A main backing having a second thermal anisotropic property different from the first thermal anisotropic property is provided behind the auxiliary backing. In the main backing, each of two outer surfaces perpendicular to a Y direction functions as a heat output surface. Heat is transferred from these two outer surfaces to a shell, which is a heat absorbing member.Type: ApplicationFiled: August 14, 2023Publication date: February 22, 2024Inventors: Takayuki Iwashita, Hiroshi Hattori, Tomohiro Shiraishi, Hidetsugu Katsura, Wataru Sawada, Sachio Shimada

Patent number: 7400101Abstract: A method and an apparatus accurately detect a rotor angle of a DC brushless motor by using a first-order difference of a detected value of a phase current. A periodic signal causing the total sum of output voltages in three control cycles to become zero is superposed over a drive voltage under current feedback control. The drive voltage is held at a constant level during the three control cycles. The phase difference between an actual value and an estimated value of a rotor angle is calculated, using the first-order differential current in each control cycle, and the estimated value of the rotor angle is calculated by follow-up computation of an observer, using the phase difference.Type: GrantFiled: October 11, 2005Date of Patent: July 15, 2008Assignee: Honda Motor Co., Ltd.Inventors: Nobuyuki Imai, Yutaka Takahashi, Tomohiro Shiraishi, Hajime Kondoh

Patent number: 7102330Abstract: An apparatus and method for controlling charging and discharging of an energy storage device. If the charging voltage that is applied exceeds a restriction determining voltage, the power value at that time is held as the charging power upper limit value. In addition, by multiplying a restriction coefficient by the charging power upper limit value while gradually reducing the restriction coefficient until the voltage drops below a restriction removal determining voltage. By setting its result as a control target value of the charging power, the charging power is gradually restricted. In contrast, if the applied charging voltage drops below the restriction removal determining voltage, the charging power is conversely gradually restored to its original state using a control target value obtained by multiplying the restriction coefficient by the charging power upper limit value while gradually increasing the restriction coefficient until the voltage equals or goes above the restriction determining voltage.Type: GrantFiled: May 19, 2004Date of Patent: September 5, 2006Assignee: Honda Motor Co., Ltd.Inventors: Shinobu Ochiai, Kiyoshi Asami, Tomohiro Shiraishi
