摘要： An image recording apparatus records an image on a recording medium by causing a recording head having an arrangement of a plurality of recording elements to conduct its main scanning for the recording medium interrelatedly in the direction opposite to the arrangement of the recording elements. The apparatus comprises a setting device to set the number of main scannings by the recording head; a main scanning device to perform recording by plural numbers of main scannings with respect to one pixel by causing the recording head to conduct its main scannings for the same recording area of the recording medium in accordance with the number set by the setting device; and a sub-scanning device to cause the recording head and the recording medium to be sub-scanned interrelatedly per main scanning in an amount smaller than the width of the arrangement of the recording elements of the recording head. Hence, even if a disabled ejection occurs in one scanning at the time of recording by a multi-scanning, the missing dot is complemented by the following scan to make it possible to obtain an image having no image defects at all times.

摘要： A color processing apparatus performs the masking process of a color image by receiving a plurality of color component signals, and has a masking circuit for performing a linear masking process for the plurality of color component signals. The masking process utilizes a plurality of coefficients each of which has a particular value. The value of at least one of the coefficients of the masking circuit is varied in accordance with levels of the plurality of color component signals. A signal indicative of an amount of one kind of colorant which is to be recorded prior to the recording of other kinds of colorants can be discriminated, and a signal level which indicates the amount of the other kinds of colorants to be recorded on the same area after the recording of the one kind of colorant is corrected in accordance with the discrimination result.

摘要： In an internal combustion engine, a variable valve-actuating mechanism includes a trigger pin operable to permit axial movement of a rocker arm concurrently with a axial movement of a rocker arm shaft. A retention member has an insertion aperture formed therein, in which the trigger pin is inserted, and which slidably supports the trigger pin in the inserting direction. The trigger pin includes upper and lower expanded portions disposed on both sides thereof in the inserting direction. The upper and lower expanded portions of the trigger pin are operable to disable sliding motion of the trigger pin, relative to the retention member, beyond a predetermined range. The upper and lower expanded portions allow the trigger pin to be integrally assembled in the insertion aperture of the retention member, so as to be selectively retained therein.

摘要： An internal combustion engine includes a variable valve control system which is operable to switch actions of an engine valve by slidably moving a rocker arm in the axial direction of a rocker-arm shaft, and which is capable of removing a restriction on the sliding movement of the rocker arm at accurate timings while employing a simplified configuration. When a trigger arm swings by a predetermined amount to the opposite side of a rocker arm, a left-hand engagement nail in engagement with an engagement groove disengages from the engagement groove, but a right-hand engagement nail still engages with an engagement groove. The left-hand engagement nail is placed on top of a left-hand deck-like portion. After that, when an action of the rocker arm makes the trigger arm further swing to the opposite side of the rocker arm, the right-hand engagement nail disengages from the engagement groove.

摘要： An internal combustion engine is equipped with a variable valve control system which is operable to selectively actuate an engine valve using one of two cams of a camshaft, by sliding a rocker arm in the axial direction of a rocker-arm shaft. The system is capable of restricting the axial-direction movement of the rocker arm within a predetermined range, using a simple structure without unduly increasing the number of component parts. Position-restriction portions are formed in a rocker arm, and abut on a trigger arm to restrict sliding movement of the rocker arm within a predetermined amount, when the trigger arm is disengaged from the rocker arm.
