Abstract: <P>PROBLEM TO BE SOLVED: To prevent occurrence of troubles, such as unauthorized read-out of data and destroy of holding data caused by performing DRAM access in a state in which voltage of a terminal power source does not reach a prescribed voltage.  <P>SOLUTION: The electronic device has a DRAM 212 and a DRAM controller 115 for controlling the DRAM 212. The DRAM controller 115 and the DRAM 212 are connected by a data transmission communication line 211. A terminal voltage supply means 209 receives a control signal from the DRAM controller 115 and carries out supplying of power source to the data transmission communication line 211. When a refresh mode of the DRAM 212 is released, the DRAM controller 115 makes the terminal voltage supply means 209 start for supplying the power source, and the controller 115 makes the means 209 wait to access the DRAM 212, from the start of power source supply by the terminal voltage supply means 209 to the release state of refresh.  <P>COPYRIGHT: (C)2008,JPO&INPIT

Title: Control device for internal combustion engine

IPC: F02D45/00
Filed: 2007-03-14
Abstract: <P>PROBLEM TO BE SOLVED: To perform an appropriate catalyst early warming-up control (air-fuel ratio dither control) corresponding to the amount of oxygen occludable in a catalyst before activation (the amount of OSC).  <P>SOLUTION: Before the catalyst is activated, a relation between the amount of OSC and catalyst temperature T is substantially a linear relation, and the amount of OSC is increased substantially linearly as the catalyst temperature T is raised. The linear relation before activation is maintained for a while even if the catalyst temperature T exceeds activation temperature T1, however, when the catalyst temperature T exceeds a certain temperature Th, the linear relation from before activation is broken. In consideration of this characteristic, the amount of OSC after activation is measured within a range of temperature after activation where the linear relation from before activation is maintained (ranges of T1 to Th), the measured data is memorized in a backup RAM, and the coefficient of an estimated equation for the amount of OSC, expressing the relation between the amount of OSC before activation and the catalyst temperature T, is determined based on multiple regression analysis by using at least two measured data of the amount of OSC after activation. Before the catalyst is activated, the amount of OSC before activation is estimated by using the estimated equation for the amount of OSC.  <P>COPYRIGHT: (C)2008,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To prevent an adhesive seeped out of an adhesion surface from adhering to an orifice and an ink channel to cure and from turning the discharge precision of an ink lowered in the process of pasting an orifice plate and a liquid discharge head together.  <P>SOLUTION: A two-liquid mixing type adhesive consisting of a main substance and a microencapsulated curing agent is used for pasting together. Only when an object to be adhered contacts under the pressure exceeding a fixed value, the microcapsule is broken and the curing agent flows out which leads to the curing of the curing agent. Since the pressure is not applied to the microcapsule in the orifice plate and ink channel, the adhesive is not cured and is able to be washed away with a solvent after pasting together.  <P>COPYRIGHT: (C)2009,JPO&INPIT
