When a PWM signal generating unit (10) sets a duty D of a PWM signal based on command signals (10c), the PWM signal generating unit (10) sets a phase difference φ between each of the PWM signals based on a relation formula of φ (degree)=360 (degree)×D (%)/100 (%), and generates and outputs first PWM signals (10a) and second PWM signals (10b) in which the duty is D (%) and the phase difference is φ (degree). The first PWM signals (10a) and the second PWM signals (10b) are respectively supplied to a first load driving circuit (21) and a second load driving circuit (22) to operate a first motor fan (3) and a second motor fan (4) by a PWM control, respectively.

A control device for a brushless motor comprises a first section which stores a data table provided to minimize a difference between an actual rotation speed of the motor and a target rotation speed of the same. The difference is inevitably produced when the motor is rotated. The data table provides a plurality of rotation speed ranges each having data for a rotation speed of the motor. The control device further comprises a second section which compares the target rotation speed and the data table to select data which corresponds to the rotation speed range to which the target rotation speed belongs. The control device further comprises a third section which corrects the target rotation speed based on the selected data and drives the brushless motor in accordance with the corrected target rotation speed.

In apparatus and method for controlling a rotation speed of a brushless motor, the rotation speed of the rotor is lowered by a predetermined gradient for the rotation speed of the rotor to be reached to a present target value of the rotation speed of the rotor when the rotor of the motor is rotating at a previous target value of the rotor of the motor previously calculated and the present target value of the rotor of the motor is lower than the previous target value thereof at which the rotor of the motor is rotating. The predetermined gradient is, for example, 100% per unit time.

Boundary lines which are contours of uneven marks are detected in a sample original image of the sidewall surface of a sample tire, and a mask image showing the position of the boundary lines is generated. Thereupon, a height offset image which shows a height of the uneven marks is generated by, in use of a plurality of discrete height threshold values, classifying the height of regions in the sample original image which remain after excluding regions corresponding to the positions of the boundary lines shown in the mask image. An unevenness-excluded image is generated by excluding the uneven marks from an inspection image of a sidewall surface of a tire under inspection, by subtracting the height offset image from the inspection image. A shape defect in the sidewall surface of the tire under inspection is inspected on the basis of the unevenness-excluded image.

Provided are a novel titania fine-particle composite which has high transparency, high stability, and high ultraviolet-absorbing power and excellent redispersibility, and skin-care external preparations which contain the titania fine-particle composite and exert high ultraviolet protective effect. The titania fine-particle composite can be produced by adding one or more selected from among carboxylic acids and carboxylic acid derivatives represented by general formula (1), and polymers containing the carboxylic acids or carboxylic acid derivatives as a constituent monomer to an aqueous acid dispersion of titania fine particles, and neutralizing the resulting dispersion with an alkali to form a titania fine-particle composite composed of titania fine particles functioning as cores and the carboxylic monomer or polymer deposited on the surface of the cores. In the titania fine-particle composite, titania fine particles functioning as cores have a high degree of crystallization and the intermolecular interaction between titania fine particles and the carboxylic monomer or polymer is strong. Therefore, the titania fine-particle composite can be uniformly dispersed in a dispersion medium to attain high transparency and high stability. Further, skin-care external preparations which exert high ultraviolet protective effect can be produced by adding the titania fine-particle composite.
