Patent number: 8841018Abstract: The purpose of the present invention is to provide simpler and more reliable electrical wiring than a lead wire. A battery pack includes at least one rechargeable secondary battery (1), a battery holder (70) for housing the secondary battery (1) in a predetermined position, a pack circuit board (74) having a mounted electronic circuit for monitoring the secondary battery (1), and an electrical connection wire (85) for electrically wiring the pack circuit board (74). Here, the electrical connection wire (85) is a bent metal wire. Because wiring is realized using metal wire, and the metal connection is secured after the wiring has been completed, movement and deformation due to vibrations and other factors, such as that which occurs in the case of conventional lead wires, are avoided, and reliability can be improved.Type: GrantFiled: November 20, 2012Date of Patent: September 23, 2014Assignee: Sanyo Electric Co., Ltd.Inventors: Masaya Nakano, Osamu Inaoka, Takao Takatsu, Haruhiko Yoneda

Publication number: 20040165452Abstract: An internal RAS generating circuit generates an internal signal instructing activation of a word line, based on a control command received from the outside. The internal RAS generating circuit activates the internal signal at least during a period in which an internal RAS guarantee signal received from an internal RAS guarantee signal generating circuit is asserted, regardless of the control command instructing inactivation of the word line. In a normal operation mode, the internal RAS guarantee signal generating circuit activates the internal RAS guarantee signal until a prescribed period guaranteeing a restoring operation elapses, while in the test mode, it inactivates the internal RAS guarantee signal.Type: ApplicationFiled: October 21, 2003Publication date: August 26, 2004Applicant: RENESAS TECHNOLOGY CORP.Inventor: Masaya Nakano
