20080198957 | APPARATUS, METHOD, AND PROGRAM FOR VERIFYING LOGIC CIRCUIT OPERATING WITH MULTIPLE CLOCK SIGNALS - A verification apparatus that can verify a circuit in a shorter time while taking possible metastability into consideration. A clock domain crossing (CDC) detector finds CDC paths between circuit elements operating with different clocks in the circuit. A delay generator inserter produces a delay-insertable version of the circuit by embedding a delay generator into each found CDC path. When activated, those delay generators give a signal delay to the corresponding CDC paths. A simulator simulates the behavior of the delay-insertable circuit by using a specified simulation pattern while deactivating the embedded delay generators. A delay pattern generator creates a delay pattern from simulation results, which activates or deactivates delay generators individually so as to produce signal delays that could affect output signals of the circuit. A verifier verifies the circuit by applying the delay pattern to each delay generator in the circuit. | 08-21-2008 |

20100012754 | FUEL INJECTION VALVE - In relation to injectors used for internal-combustion engines, it is important to decrease valve closing delay time and also the minimum injection quantity, while these are affected by remanent magnetism in the fixed core, surface tension of the fuel, etc. With reference to a fuel injection valve with a pipe-shaped member to enclose a fixed core and a movable part and further with coils and yokes to cover up the above pipe-shaped member, the anchor to drive the movable member has a plurality of through holes for fuel passage extending in the axial direction, while these through holes are arranged at a certain intervals in the circumferential direction, and projections formed to constitute a contacting surface to touch the fixed core arranged randomly in between the through holes. | 01-21-2010 |
20100065021 | Fuel Injection Valve - In a fuel injection valve used for an internal combustion engine, a valve closing lag time due to fluid resistance in a fuel path is shortened to decrease a minimum injection limit. More specifically, in the fuel injection valve in which an anchor is attracted to an end face part of a stationary core having a fuel path formed at a center part thereof by means of electromagnetic force, and in which a fuel injection hole is opened and closed by controlling a valve disc driven in conjunction with the anchor, there are provided a fuel reservoir part at a center part of an upper end face part of the anchor, a through hole extending axially in a fashion that an end part thereof is open to the fuel reservoir part, and a fuel path extending radially outward from the fuel reservoir part so that fuel is fed to a magnetic attraction gap between an upper end face part of the anchor and a lower end face part of the stationary core. Further, an opening part of a through hole that is open to an upper end face part of the anchor is at least partially opposed to a fuel introduction bore formed in the stationary core, and on the opening part of the through hole, a fuel introduction part is provided for capturing fuel running radially outward from a center side part of the anchor and for guiding the fuel thus captured to the through hole. | 03-18-2010 |
20110042491 | Fuel Injection Valve - An injector used for an internal combustion engine, wherein force acting on a valve element due to flow of fuel is reduced. The shape of either a valve element front end or a valve seat surface of a fuel injection valve is adapted such that the distance between the valve element front end and the valve seat surface which is formed by a circular conical surface is greater than in the case when the shape from a valve element circular tube surface to a spherical surface which forms a seat is connected by a circular arc. As a result, the cross-sectional area of a flow path is rapidly increased from the valve seat surface, on the outer side of the valve element, and this reduces that portion of the valve element which receives pressure due to a reduction in static pressure, reducing force acting on the valve element. | 02-24-2011 |
20110155103 | Fuel Injection Valve for Internal Combustion Engine - In a fuel injection valve, it is intended to enhance valve-closing responsivity while maintaining durability (anti wear property) of a collision portion between a stationary core and a movable core and valve-opening responsivity. | 06-30-2011 |
