A recording material moving device comprises: a position adjuster that moves a recording material in a direction which is parallel to a recording surface of the recording material and orthogonal to a transporting direction, in an upstream side of a recording position along the transport direction of the recording material; a reference position specifying unit that specifies a reference position; a determination unit that determines whether a range of a predetermined width centered on the reference position exceeds a movable range of the recording material within which the recording material can be moved by the position adjuster; and a controller that causes, if the determination unit determines that the movable range is not exceeded, the position adjuster to sequentially move the recording material within the movable range of the predetermined width centered on the reference position each time a condition for moving the recording material is satisfied.

A surface inspecting method including irradiating a laser light to a test object to generate an ultrasonic wave, irradiating a second laser light at a position apart by a known distance from a position where the laser light is irradiated and receiving a reflection light thereof, and correcting a generation surface wave of a received ultrasonic wave by using an ultrasonic wave other than the generation surface wave to thereby detect a flaw of the test object. A characterization of the generation surface wave is divided or integrated by the same characterization of the ultrasonic wave other than the generation surface wave included in an output signal to obtain a performance index value and obtain a depth of the flaw by applying the performance index value to a calibration curve in which a corresponding relation between the performance index value and the depth of the flaw is obtained preliminarily.

An image forming device has plural photoreceptor drums on which a latent image is formed, wherein one of the photoreceptor drum is different diameter from the other photoreceptors. A belt in contact with the plural photoreceptor drums and plural transfer rollers press the photoreceptor drums from a side of the belt, the side being opposite to the side contacts with the photoreceptor, wherein a distance from a contact reference position. The contact reference position at which the photoreceptor contacts with the belt, to a pressed position of the transfer roller of a large-diameter photoreceptor drum is greater than that of a small-diameter photoreceptor drum.

According to one embodiment, an information integration control system includes a collector, a storage module and a generator. The collector collects infrastructure information concerning a social infrastructure, user information about a user who uses the social infrastructure, and management information of a manager who manages the social infrastructure and the user. The storage module stores the infrastructure information, the user information, and the management information which are collected. The generator generates control information for the social infrastructure based on the infrastructure information, the user information, and the management information which are stored in the storage module.

A welding system has: a welding mechanism, a reception laser light source, a reception optical mechanism, an interferometer, a data recording/analysis mechanism and a data recording/analysis mechanism. The reception laser light source generates reception laser light so as to irradiate the object to be welded with the reception laser light for the purpose of detecting a reflected ultrasonic wave obtained as a result of reflection of a transmission ultrasonic wave. The reception optical mechanism transmits, during or after welding operation, the reception laser light generated from the reception laser light source to the surface of the object to be welded for irradiation while moving, together with the welding mechanism, relative to the object to be welded and collects laser light scattered/reflected at the surface of the object to be welded.
