Magnetic materials which are divided into a plurality of blocks or divided corresponding to respective magnetic pole teeth are connected by means of thin portions. The respective magnetic pole teeth are wound continuously with wire without cutting the wire at the positions in which the thin portions are connected. When a stator is assembled, a plurality of blocks or magnetic pole teeth are disposed on a substrate by separating or bending the thin portions.

This invention provides a small-sized and easy assembling head positioning apparatus having a coarse moving mechanism and fine moving mechanism, by which the desired fine moving accuracy is easy to attain. A head positioning apparatus has a first stepping motor, a lead screw, and a cylindrical rack for coarse moving. The cylindrical rack is formed by rotating a rack around the axis of the lead screw and is provided with the lead screw. The head positioning apparatus has a second stepping notor and gears for reducing the speed of the rotation of the second stepping motor for fine moving means, and fine moving is carried out by moving the cylindrical rack by the gear. The lead screw is provided so that the first stepping motor could be moved in a X1, X2 direction in the fixed moving range.

Provided is a wave-power generator capable of adjusting a natural period (natural frequency) in response to a changing wave period. The wave-power generator includes a weight that is installed in a floating body via a spring and that linearly reciprocates in response to a fluctuation of a water surface and a generator that generates power by being driven based on the linear reciprocating motion of the weight. An additional-mass body for adding a mass to the mass of the weight is further included.

A projector includes: a light source lamp; and a cooling device that cools the light source lamp and includes a plurality of cooling fans to deliver air toward the light source lamp. Airflow directions in which the plurality of cooling fans deliver the air toward the light source lamp are different from each other.

The present invention relates to a toner which has good property such as fixability, coloring power, developability, durability, and environmental stability and so on. More specifically, the present invention relates to a color toner containing at least a binder resin, a colorant, and a wax, in which: a wax concentration of an extract obtained by dispersing the toner into n-hexane at a concentration of 15 mg/cm3 at 23° C. and by subjecting the resultant dispersion to extraction treatment at 23° C. for 1 minute is in the range of 0.080 to 0.500 mg/cm3; an average circularity of particles each having a circle-equivalent diameter of 3 μm or more in the toner is in the range of 0.925 to 0.965; and a content of the wax is in the range of 1 to 15 parts by mass with respect to 100 parts by mass of the binder resin.

A method for manufacturing a ceramic electronic component includes first and second gravure-printing steps in which conductive paste and step-reducing ceramic paste are printed on a composite sheet including a ceramic green sheet. A first print mark is printed before the second gravure-printing step is performed, and the position of the first print mark is determined and compared with a desired position of the first print mark before the second gravure-printing step. Then, the second gravure-printing step is performed such that a second print mark is printed at a suitable position with respect to the position of the first print mark.

From a number of fish heads W of the same kind of fish and of roughly the same shape, pituitaries M as useful portions in the fish heads W are collected. A useful portion line is preliminarily determined which passes pituitaries M as useful portions of the number of fish heads W having different sizes when the fish heads W are rested in a specific posture, and each of fish heads W to be processed is rested in the specific posture, and the rested fish head W is cut in the vicinity of the preliminarily determined useful portion line substantially along the useful portion line to expose an useful portion, and a brain as an untargeted portion which is present in a cut surface F is removed to expose the pituitary M, and the exposed pituitary M is collected.
