An intake passage in an internal combustion engine includes an independent passage disposed in each of cylinders, and a common passage connected to the independent passage, to be commonly used by the different cylinders. A cross-sectional area of the independent passage disposed in the cylinder having the long passage length from an intake valve to a surge tank is made greater than that of the independent passage disposed in the cylinder having the short passage length.

To maximize the life of a rechargeable battery and the life of cells forming the rechargeable battery, the rechargeable battery is so constructed that each of the cells forming the rechargeable battery can be charged independently of the other cells. To charge this rechargeable battery, a cell to be charged is selected, and the selected cell is charged.

An lubricating oil from an oil pump that is driven by rotation of an engine is supplied as a refrigerant to a rotor of an assist motor via a pressure valve. The pressure valve is configured to be closed when the pressure of the lubricating oil is less than a predetermined value, and to open when the pressure of the lubricating oil is greater than or equal to the predetermined value. As a result, when the rotor is in low need for cooling down because the temperature rise of the rotor is small although the rotation speed of the rotor rises, that is, when the engine is operating at a low rotation speed with a high load, the supply of lubricating oil to the rotor is reduced or stopped.

A control method with variable feedback gain for energization of an electro-magnetically driven intake/exhaust valve of an internal combustion engine increases opening and closing speeds of the intake/exhaust valve driven with electromagnets having small capacity and brings the final speed of the opening and closing action of the valve close to zero. A target moving speed of the armature relative to the electromagnets is determined dependent upon a spacing distance of the armature from the electromagnet; at least a part of energization of the electro-magnetically driven valve is controlled through feedforward control so as to make an actual moving speed of the armature relative to the electromagnets in conformity with the target moving speed while at least the other part of the energization is controlled through feedback control based upon a deviation of the actual moving speed from the target moving speed.

In order to realize stable image printing, this invention provides an image printing apparatus capable of supplying a stable voltage to a printhead, and maintaining a compact shape. For this purpose, in the image printing apparatus in which a carriage which supports a printhead is scanned on a printing medium to print an image, a power converter which converts power to be supplied to the printhead is mounted on the first print circuit board of the carriage so as to supply a predetermined voltage to the printhead. The printhead and a power smoothing unit which smoothes the voltage converted by the power converter in accordance with the load of the printhead are mounted on the second print circuit board. The first and second print circuit boards are separately arranged at a proper gap in the image printing apparatus, which prevents an increase in the size of the image printing apparatus.

A cylindrical member including a cylindrical substrate and at least one coating layer thereon is formed through an applying step of applying a coating liquid on the cylindrical substrate and a drying step of drying the coating liquid that has been applied in the applying step by induction heating device to form the coating layer. The induction heating device is disposed in the interior of the cylindrical substrate. The induction heating device has an excitation coil for generating a magnetic flux in a direction perpendicular to the axial direction of the cylindrical member. The excitation coil is disposed along the inner surface of the cylindrical substrate.

An image information recording apparatus is arranged to record compressed image information within a predetermined section of a recording tape extending from a beginning of the tape, to record non-compressed image information in another section located after the predetermined section, and to record, also within the predetermined section, positional information indicative of a position where the non-compressed image information which corresponds to the compressed image information is recorded on the tape, so that all recorded images are quickly graspable and any of the non-compressed images thus can be quickly extracted. Further, in recording image information of a plurality of kinds, a non-recorded area of a tape-shaped recording medium is divided and a divided recording area thus obtained is allocated to some of the image information of different kinds, so that the tape-shaped recording medium can be efficiently used.

A solenoid valve device includes an engine valve which can move in an axial direction thereof, an armature which moves with the engine valve, an electromagnet which attracts the engine valve so that the engine valve moves in the axial direction, and a zero-lash adjuster mechanism which is interposed between the engine valve and the armature. Thus, the solenoid valve can positively actuate an engine valve between a fully closed position and a fully opened position without formation of a clearance between the engine valve and the armature. A current supplied to the electromagnet may be set in accordance with a value which is related to a relative position of the armature and the electromagnet.
摘要:
A method of making an electric circuit device by connecting first and second electrical circuit components through an electrical connecting member. The method comprises effecting internal heating such as supersonic heating, high-frequency induction heating, high-frequency dielectric heating or microwave heating at first connecting regions between the connecting portions of the first electrical circuit component and the first ends of the electrically conductive members of the electrical connecting member. The same internal heating may also be effected at second connecting regions between the connecting portions of the second electrical circuit component and the second ends of the electrically conductive members of the electrical connecting member. In consequence, alloying takes place in first and second connecting regions so as to connect the first and second electrical circuit components through the electrical connecting member.
