摘要： A control apparatus for an internal combustion engine can compensate for a variation of intake pressure resulting from various factors whereby a failure detection area can be expanded, and false detection can be prevented to enable failure determination for an EGR system with high reliability. The apparatus determines whether a vehicle is decelerating, forcedly opens and closes an EGR valve, and determines whether an EGR control device is in failure by comparing a pressure change index value based on intake pressures upon the forced opening and closing of the EGR valve with a failure determination value. The apparatus adjusts the intake pressure to a predetermined state before the EGR valve is forcedly opened and closed, whereby a failure determination can be always made based on the intake pressure whose variation was compensated for with the intake pressure becoming a predetermined characteristic to the number of revolutions per minute of the engine.

摘要： A laser exposure device at which alignment marks of a plate material on an exposure stage, which is moving in a direction opposite to a scanning direction, are read by a CCD camera mounted at a support gate, after which an imaging region, whose position is judged using the alignment marks, is exposed by a laser beam from a laser scanner. Here, a distance along the scanning direction from the CCD camera to the laser scanner is not less than a pitch of the alignment marks that are provided to respectively correspond to a trailing end and a leading end of the imaging region. According to this laser exposure device, even in a case in which a plurality of the imaging region is provided at a recording medium, an increase in a duration for forming images on the recording medium in accordance with an increase in imaging regions is prevented.

摘要： A valve timing control apparatus for an engine. Presence/absence of a torque demand (xtq) is estimated upon starting of a lock pin release control to thereby alter a change rate (&bgr;) of a target phase angle in dependence on presence/absence of the torque demand (xtq). Unless torque demand is issued, the change rate is set to a small value (&bgr;2) for suppressing the change of the target phase angle (&thgr;t) after detection of release of the lock pin in order to avoid a shock unexpected by a driver. When the torque demand is issued, the change rate is set to a large value (&bgr;1) for allowing the target phase angle to approach speedily to a base target phase angle (&thgr;map) for thereby minimizing a delay in response involved in the phase angle detection through the lock pin release control.

摘要： A plurality of joined members each made of thermoplastic resin and having a fluid flow path formed of a groove and/or a hole in a junction face are vacuum-packed in a state in which the joined members are joined to each other. After a wrapped body obtained by the vacuum-packing is heated to soften the joined members, the joined members are welded to each other through the junction faces by applying fluid pressure to an entire outer periphery of the wrapping to evenly pressurize the wrapping from a periphery. Then, the pressurization is cancelled to cool the welded joined members.
