The image forming apparatus includes a chassis, a paper guide, a paper feed roller, and a paper supply portion from which the paper feed roller is configured to supply paper. The paper guide is supported within the chassis and has a base portion and a first separation portion that projects from the base portion. The paper feed roller is rotatably supported by the chassis. The paper supply portion has a guide projection on its first lateral side portion. The widthwise center of the paper feed roller is offset toward the first lateral side relative to the widthwise center of the first separation portion.

A positive type radiation-sensitive resin composition suitable as a chemically-amplified resist sensitive to active radiation particularly to deep ultraviolet rays represented by a KrF excimer laser, an ArF excimer laser, or an F2 excimer laser, excelling particularly in a process margin for the KrF excimer laser is provided. The positive type radiation-sensitive resin composition comprises a photoacid generator and an acid-labile group-containing resin which is insoluble or scarcely soluble in alkali, but becomes alkali-soluble by the action of an acid, wherein the photoacid generator is a mixed photoacid generator containing a photoacid generator of the following formula (1) and a photoacid generator which is at least one compound selected from sulfonyloxyimide and disulfonyldiazomethane.

A radiation-sensitive resin composition is provided which exhibits improved resolution, sensitivity, and focal depth allowance (process margin) and can eliminate development residues when forming a resist pattern. The radiation-sensitive resin composition comprises an acid-labile group-containing resin (A) which is insoluble or scarcely soluble in alkali, but becomes alkali soluble by the action of an acid, and a photoacid generator (B), the acid-labile group-containing resin (A) comprises a copolymer prepared by anionic polymerization of monomers including a substituted or unsubstituted styrene and have a terminal shown by the following formula (x). wherein R14 and R15 individually represent a hydrogen atom or a linear or branched saturated hydrocarbon group having 1-6 carbon atoms.
摘要:
There is provided a valve timing control system for an internal combustion engine, which makes it possible to secure a right amount of combustion gases in a combustion chamber, irrespective of whether an EGR device is in operation or not, thereby obtaining a sufficient effect of reduced exhaust emissions by reduction of NOx. A crank angle position sensor and an intake pipe absolute pressure sensor detect operating conditions of the engine. An ECU determines whether the EGR device is in operation or not. A target cam phase is set in dependence on the detected operating conditions of the engine and a result of the determination as to whether the EGR device is in operation or not, and the cam phase is controlled to the target cam phase.

There is provided a fuel supply control system for an internal combustion engine installed on an automotive vehicle. The engine has an exhaust system, and an exhaust gas-purifying device arranged in the exhaust system. A start of the engine is detected. A combustion stability of the engine is detected. The air-fuel ratio of a mixture supplied to the engine is leaned over a predetermined time period from the start of the engine depending on the detected combustion stability.
摘要:
An air-fuel ratio control system for an internal combustion engine has an air-fuel ratio sensor arranged in the exhaust system of the engine, for detecting the air-fuel ratio of exhaust gases emitted from the engine, and various engine operating parameter sensors for detecting operating conditions of the engine. An ECU controls the air-fuel ratio of an air-fuel mixture to be supplied to the engine to a desired air-fuel ratio in a feedback manner responsive to an output from the air-fuel ratio sensor. A first learned value for correcting the desired air-fuel ratio is calculated based on the feedback control when the engine is detected to be in a first predetermined operating condition, and a second learned value for correcting the desired air-fuel ratio when the engine is detected to be in a second predetermined engine operating condition. The air-fuel ratio of the air-fuel mixture is controlled to a value leaner than a stoichiometric value, by using the first learned value. The first learned value is learned again when the difference between the first and the second learned values is larger than a predetermined re-learning-determining threshold value.
摘要:
The present invention provides a piezoelectric sensor that can reduce spurious vibration of a transducer. The piezoelectric sensor includes a transducer which has a piezoelectric body and a vibration plate and which transmits/receives ultrasound, and a mount supporting the transducer near nodes of mechanical vibration generated to the transducer. The mount includes ribs that contact the transducer near the nodes of vibration in a point by point, line by line or partially plane by plane contact manner to support the transducer, and retract portions which are provided side by side to respective ribs near the nodes of vibration and which are distant from the transducer so as not to support the transducer.
