In the lens driving device of the present invention, at least two second coils are disposed at a 90 degree interval in a circumferential direction of a first coil wound around an outer circumference of a lens support in the circumferential direction, at least four magnets are provided at an inner circumferential side of a circumferential wall of a yoke and are provided at even intervals about the circumferential direction of the first coil, each magnet being provided so that an inner circumferential face is the same magnetic pole and opposes an outer circumferential face of the first coil, and in addition is opposite the second coil at the position of providing the second coil. When the lens support is moved in the optical axis direction, an electric current flows in the first coil, and when the lens support is moved in an X-Y direction orthogonal to the optical axis, a predetermined electric current flows in a predetermined second coil.

A color laser printer of the invention identifies each object image to be printed as a color image or a monochromatic image. When the object image to be printed is identified as a color image, the control procedure of the invention rotates a developer unit with multiple color toner cartridges to sequentially move positions of the respective color toner cartridges to a development position and forms respective color toner images on a photoreceptor. When the object image to be printed is identified as a monochromatic image, on the other hand, the control procedure fixes a specific toner cartridge filled with black toner to the development position and forms a black toner image on the photoreceptor. A counter counts up consecutive monochromatic printing operations. After a preset number of the consecutive monochromatic printing operations in the fixed state of the developer unit, the developer unit is rotated to return and fix the specific toner cartridge filled with black toner to the development position for monochromatic printing.

A toner comprising: a plurality of mother particles; and a plurality of external additive particles to be attached to the mother particles, the external additive particles including external additive particles attached to the mother particle and external additive particles liberated from the mother particles, wherein an inclination (particle sizes of the external additives/particle sizes of the mother particles) of an approximation straight line obtained by approximating distribution of particle sizes of the external additives with respect to the particle sizes of the mother particles by a least-square method is not larger than 0.6. Also, disclosed is an image forming apparatus using the toner.

A electromagnetic relay includes a spool, a coil, a U-shaped yoke, an armature, a movable contact, a pair of stationary contacts, and a taper. The spool has an inner hole and first and second flange portions formed at its two ends. The coil is wound on the spool. The yoke is locked at the flange portions of the spool by press fitting to stride over the coil. The armature is movably connected to one end of the yoke and positioned to extend through the inner hole of the spool. The movable contact is attached to move in an interlocked manner with the armature. The pair of stationary contacts are arranged to sandwich the movable contact. The taper is formed on at least one of press-fit locking surfaces of one end of the yoke and the first flange portion, and has a locking force that increases as being closer to a vicinity of the inner hole of the spool. A method of adjusting an electromagnetic relay, and a method of assembling an electromagnetic relay are also disclosed.

Provided is an optical disc apparatus and an optical disc recording method, in which it is decided whether or not an optical disc recording medium is one of DVD-RW and DVD+RW when data is recorded in the medium. If it is decided that the medium is one of DVD-RW and DVD+RW, maximum length information is read out from a storage portion. The maximum length information contains a previously set maximum data length of data recorded to the medium by an optical pick-up portion in one recording operation. Data to be recorded is split into split data having a data length of the maximum data length or smaller. Further, an electric power value of a base electric power for controlling the semiconductor laser element to emit a laser beam with a bottom power is reset every recording operation of the split data.

In a steering system having a variable gear transmission system and an electrical power steering system, respective compensation amounts for first and second electric motors are produced by a first mathematical model. The compensation amounts are added to command values (v1, v2) to generate final command signals (igref, ipref) to the respective electric motors. According to the above structure and operation, a mutual interference between two control systems can be suppressed.
