Title: Memory element and memory device
Inventor: OBA KAZUHIRO
IPC: H01L27/10
Filed: 2007-08-06
Abstract: <P>PROBLEM TO BE SOLVED: To provide a resistance variation-type memory device which can improve the capability of retaining the resistance value of a stored state and an erased state.  <P>SOLUTION: A memory layer 5 comprising a high-resistance layer 2 and an ionization layer 3 is provided between a lower electrode 1 and an upper electrode 4. The ionization layer 3 contains Al (aluminum) as an additive element together with an ion conductive material such as S (sulfur), Se (selenium), and Te (tellurium)(a chalcogenide element) and a metal element to be ionized such as Zr (zirconium). Since Al is contained in the ionization layer 3, an Al-containing high-resistance layer (an Al oxide) is formed on an anode electrode in the erasing operation. This can contribute to an improvement in retaining properties in the high-resistance state and, at the same time, can improve the operating speed.  <P>COPYRIGHT: (C)2009,JPO&INPIT

IPC: H02M3/155
Filed: 2007-08-17
Abstract: <P>PROBLEM TO BE SOLVED: To provide a DC low voltage output circuit whose power voltage of a micro computer can be made low.  <P>SOLUTION: Secondary winding Ns of a pulse transformer PUT is connected to a gain adjusting part G through a diode D of illustrated polarity. A gain adjusting part G gain-adjusts rectification voltage of the diode D and supplies voltage to a voltage control oscillation circuit PLL. Since the voltage control oscillation circuit PLL is constituted of an operand amplifier, rectification voltage is gain-adjusted by the gain adjusting part G so that an input pin of the operand amplifier becomes not more than in-phase input voltage so as to be inputted. When input voltage which is gain-adjusted is supplied to the voltage control oscillation circuit PLL, the voltage control oscillation circuit PLL outputs oscillation voltage whose frequency changes in proportion to input voltage. Outputted oscillation voltage is supplied to a transistor Tr, and oscillation voltage is converted into a micro computer Vcc range and is outputted.  <P>COPYRIGHT: (C)2009,JPO&INPIT

IPC: F02D45/00
Filed: 2007-08-27
Abstract: <P>PROBLEM TO BE SOLVED: To provide a knock detection device capable of performing an accurate knock determination.  <P>SOLUTION: The knock detection device includes a vibration detecting means, a characteristic value calculating means, a median calculating means, a standard deviation calculating means, a knock determining means, and a steady noise switch determining means.

The steady noise switch determining means determines whether a steady noise occurring in the internal combustion engine is switched. The median calculating means, when the steady noise switch determining means determines that the steady noise is switched, sets the characteristic value calculated by the characteristic value calculating means to the median. Thus, even in case that a knock occurs in a transition period immediately after the steady noise being switched, the accurate knock determination can be performed.  <P>COPYRIGHT: (C)2009,JPO&INPIT
