In a printing apparatus having a mechanism for feeding a printing medium relative to the printing head having an array of a plurality of printing elements, when it is necessary to shift the positions of data to be set in the printing elements by an amount smaller than 8 bits, a basic unit used for data processing, according to the printing medium feeding amount determined by a printing resolution, a trouble of re-editing the print data is avoided. To achieve this, 8 bits of blank data are added to the print data to be transferred to the plurality of printing elements and the number of clocks for transferring the print data is reduced by an amount corresponding to the data position shifting. This allows the print data to be freely allocated to the appropriate positions of the printing elements without having to re-edit the data.

A microscope objective lens having a large aperture and yielding satisfactorily corrected, flat images. The microscope objective lens includes, in order from the object side, a first lens group G1 having an overall positive refractive power and a second lens group G2. The second lens group G2 includes plural Gauss lens sets G2A, G2C. Each Gauss lens set is formed of, in order from the object side, a meniscus-shaped optical element with its concave surface on the image side, and a meniscus-shaped optical element with its concave surface on the object side. Preferably, each of these meniscus-shaped optical elements is formed of two lens elements that are cemented together. Prescribed conditions are set forth to favorably correct various aberrations.

A charge/discharge control method for an alkaline storage battery (11) includes: obtaining in advance a coefficient (K) representing characteristics of a memory effect of the alkaline storage battery; causing the alkaline storage battery to perform a charge/discharge between a lower-limit depth-of-charge (SOCb), of which a depth-of-charge is set within a range of 10% to 30%, and an upper-limit depth-of-charge (S), of which a depth-of-charge is set within a range of 70% to 90%; calculating an additional charge electricity quantity (C) based on the coefficient (K), the upper-limit depth-of-charge (S), and a predetermined reference time (T); measuring a charging/discharging time during which the alkaline storage battery performs the charge/discharge; and performing a charge of the alkaline storage battery with the calculated additional charge electricity quantity added to the upper-limit depth-of-charge, each time when the measured charging/discharging time reaches the reference time.

The present invention provides a highly reliable spectral module. When light L1 proceeding to a spectroscopic unit (4) passes through a light transmitting hole (50) in the spectral module (1) in accordance with the present invention, only the light having passed through a light entrance side unit (51) formed such as to become narrower toward a substrate (2) and entered a light exit side unit (52) formed such as to oppose a bottom face (51b) of the light entrance side unit (51) is emitted from a light exit opening (52a). Therefore, stray light M incident on a side face (51c) or bottom face (51b) of the light entrance side unit (51) is reflected to the side opposite to the light exit side unit (52) and thus is inhibited from entering the light exit side unit (52). Therefore, the reliability of the spectral module (1) can be improved.

With conventional test discs, changing them takes much time when a pickup is subjected to signal evaluation with respect to DVD- family discs (DVD-R and DVD-RW) and DVD+ family discs (DVD+R and DVD+RW), leading to low testing efficiency. A test disc of the invention has, formed on a single glass substrate, areas where there are provided regions where pits or no pits are formed and areas where there are provided regions where wobbles and land prepits are formed with varying parameters.

A fan motor includes: a stepping motor for rotating a rotating shaft; an impeller rotated by the rotating shaft; and a connecting member for rotatably connecting the impeller relative to the rotating shaft. The connecting member absorbs an inertia force of the impeller while idly rotating the rotating shaft relative to the impeller in starting the motor and rotating the impeller to follow the rotating shaft as a revolution number of the rotating shaft increases.

A compact optical system includes a reduced number of lens elements with a bendable optical path and so is compatible with miniature image pickup devices. The image pickup lens includes, in order from its object side, a first lens element having a negative refracting power, a second lens element having positive refracting power, a stop, a third lens element having a negative refractive power and a fourth lens element having positive refracting power, and satisfies the following conditions (1) and (2) 50>&ngr;d1−&ngr;d2>10 (1) 2>f/f3>0.35 (2) where &ngr;d1 is the d-line reference Abbe number of the first lens element, &ngr;d2 is the d-line reference Abbe number of the second lens element, f is the focal length of the image pickup lens, and f3 is the composite focal length of the third and fourth lens elements. Between the first and the second lens element there is interposed a reflecting surface.
