There is provided an information providing device which, even when one advertisement display area is shared between a plurality of advertisers, can increase the probability that, for example, a banner advertisement of each advertiser is specified and efficiently display information matching each advertiser. The information providing device is configured to, when a user of a terminal device specifies an advertisement display area, specify a partial area including a position specified in the advertisement display area, and transmit information matching a provider allocated to the partial area to the terminal device.

A motor driver according to the invention comprises (i) an energizing unit supplying drive voltage and drive current to a motor including a moving body and coils, (ii) a speed-position detector detecting a drive speed of the motor and a position of the moving body to output a speed position signal including drive-speed information and position information. The motor driver also includes (iii) a reference signal generator outputting a reference signal, (iv) a phase signal generator using the speed-position signal, the reference signal, and a set signal to output a phase signal indicating a phase of the supplied drive voltage, and (v) a waveforms generator using the position information and the phase signal to output a control signal to the energizing unit. A phase of the supplied drive voltage is regulated to be proportional to the drive speed, wherein a degree of the proportion is set by the set signal.

A stator 13 on whose outer circumference a plurality of magnetic poles 13a are arranged is mounted on a substrate 11, and a rotor 14 is rotatably disposed around the stator. The inner circumferential face of the rotor is provided with a magnet 15 magnetized to have alternately opposite polarities in a direction opposing the stator, and magnetized to have alternately opposite polarities in a direction opposing the substrate. The outer circumferential ends of the magnetic poles of the stator are provided with a first extended portion 13c that extends from a magnetic pole base 13d to the substrate side, and a second extended portion 13b that extends from the magnetic pole base to a side opposite the substrate side. A face of the substrate opposing the rotor is provided with a FG pattern 19 outside the outer circumferential face of the stator such that the FG pattern opposes the magnet. Accordingly, it is possible to improve the precision in detecting the rotational speed by reducing noise superimposed on the FG signal, while securing a high driving efficiency.

A method of manufacturing a semiconductor device includes providing a semiconductor wafer and forming at least one first trench in the wafer having first and second sidewalls and a first orientation on the wafer. The first sidewall of the at least one first trench is implanted with a dopant of a first conductivity at a first implantation direction. The first sidewall of the at least one first trench is implanted with the dopant of the first conductivity at a second implantation direction. The second implantation direction is orthogonal to the first implantation direction. The first and second implantation directions are non-orthogonal to the first sidewall.

A motor driving device (100) includes an inverter (20), a speed control unit (40), and a regeneration preventing means (50). The inverter (20) converts supplied DC power to driving power for driving a motor (10), and supplies the driving power to the motor (10). The speed control unit (40) generates a speed control signal group based on a speed command signal Sref and a speed detection signal N, and adjusts the driving power based on a drive control signal VSP1 included in the speed control signal group, thereby controlling the speed of the motor (10). The regeneration preventing means (50) determines whether the motor (10) is in a state possibly causing regenerative phenomena or in a state not causing regenerative phenomena based on the speed command information included in the speed command signal Sref and the speed detection information included in the speed detection signal N, and performs a regeneration reduction process to reduce regenerative phenomena according to the determination result, thereby preventing regenerative phenomena.

An image forming apparatus of the present invention includes a movable body to be charged and a charger including a charging member that contacts or adjoins the body to be charged and applies a voltage, including an AC component, to the charging member for thereby charging the body. A protection substance for protecting the surface of the body from deterioration ascribable to charging is caused to exist on the body. The number of particular elements, contained in the protection substance and detected by an X-ray photon spectral analyzer (XPS) in a zone where the charging member charges the body, is held in a particular ratio to the total number of all elements constituting the outermost surface of the body and also detected by the XPS.
