Abstract: An image forming apparatus forms an image on a continuous medium, fixes the image by a fixing unit, and winds the continuous medium. The fixing unit has a first rotating member on a fixing surface side of the continuous medium and a second rotating member facing the first rotating member. The first rotating member is separate from the continuous medium when tension is applied to the continuous medium while the first rotating member is separate from the second rotating member. The image forming apparatus includes a tension applying mechanism, upstream and downstream nip portions, and a controller. The controller separates the first rotating member from the second rotating member while tension is applied to the continuous medium, and rotates the first rotating member. During a temperature raising operation and a temperature maintaining operation, the controller causes the nip portions to be in pressing states and maintains the tension.

Abstract: Disclosed is an image forming apparatus, which may be capable of forming an image on a continuous print medium and which may include: a fixing part that may come in contact with and heat a continuous print medium so as to fix an image formed on the continuous print medium; and a hardware processor that may perform temperature rise control of the fixing part. The fixing part may be capable of performing temperature rise control of the fixing part in a state where the contact of the fixing part with respect to the continuous print medium is released and the continuous print medium is stopped, and the hardware processor may prohibit the temperature rise control of the fixing part in a case where the hardware processor determines that a tension is not uniformly applied to the continuous print medium.

Abstract: An optical system driving device, includes: a carriage on which an objective lens is mounted; a guide for slidably supporting the carriage to guide the carriage in a tracking direction; at least a pair of coils which are attached to both sides of the carriage and which are wound in a direction perpendicular to a plane including the tracking direction and an optical axis of the objective lens; and at least a pair of magnet sections which are opposed to the coils so as to sandwich the carriage, wherein each of the pair of magnet sections has a permanent magnet in which two magnetic poles are arranged in a direction perpendicular to the plane including the tracking direction and the optical axis of the objective lens, and the two magnetic poles of one permanent magnet are arranged in an opposite direction of the two poles of the other permanent magnet.

Abstract: A disc drive is constructed from a main body which includes a mechanism unit having a disc rotating mechanism for rotating a disc and a play back mechanism for playing back information recorded on the disc, disc tray movably provided with respect to the main body for supporting a disc and a casing for housing the main body. The disc drive is provided with vibration absorbing members for suppressing transmission of vibration caused by high speed rotation of the disc from the main body to the casing. The vibration absorbing members are formed of elastical members and they are arranged between the side portions of the main body and the inside of the casing, thereby the main body is supported by the casing through the vibration absorbing members to prevent vibrations caused in the main body from being transmitted to the casing.

Abstract: A spar buoy is so arranged that a buoyancy body (1) is provided halfway on a marker mast (2), the lower end of the marker mast (2) being moored to a sinker (7) sunk at water bottom by a mooring device (6) and that the buoyancy body 1 is pulled in the water so that the water line comes to halfway on the marker mast (2) above the buoyancy body (1), the spar buoy comprising at least two arms (8, 8) protruded in opposite directions to each other from the marker mast (2) below the buoyancy body (1), and blades (9, 9) attached to the end of each arm (8) so as to have a positive angle of attack .alpha. toward the center of the buoy.

Abstract: A spar-buoy type boring device including a main pipe and a central pipe installed in the main pipe. The main pipe, which has a service deck at the top and a float near the top so that the float stays underneath the water, is anchored at the bottom to a sinker which is placed on the seabed, and the central pipe with the bottom end opening in the sea is used for guiding boring equipments to the seabed and collecting samples from the seabed.
