摘要:
A positioning adaptive control method and positioning device which allow rapid positioning of a head by speed-controlling a seek operation in an information storage device such as a magnetic disk unit. The seek operation moves the head to a vicinity of a target track and a following operation causes the head to accurately follow a position on the target track when the head is positioned in the vicinity of the target track. These operations are controlled based on data recorded in sectors formed on a recording plane of a disk. A variable gain of an acceleration feed forward signal is controlled sequentially by an adaptive control rule so that a deviation signal between a target speed and an actual speed of the head is reduced when the speed of the head is shifted from an acceleration or constant speed state to a deceleration state under speed control. The variable gain of the acceleration feed forward is used per each sampling for the adaptive control rule and a square value of the speed deviation signal is minimized.

A vibration transducer includes a silicon single crystal vibration beam provided over a silicon single crystal substrate, the vibration beam having a sectional shape that is longer in a direction perpendicular to a surface of the silicon single crystal substrate than in a direction parallel with it, a shell made of silicon, surrounding the vibration beam with a gap, and forming a vacuum room together with the silicon single crystal substrate, a plate-like first electrode plate disposed parallel with the surface of the silicon single crystal substrate, the first electrode plate having one end connected to the vibration beam, plate-like second and third electrode plates disposed parallel with the surface of the silicon single crystal substrate so as to be opposed to each other with the vibration beam interposed in between, and asperities formed on confronting side surfaces of the vibration beam and the second and third electrode plates.

A magazine detachably installed in a main body of a disc changer is divided into sections by partitions for storing a large number of optical discs. The magazine is provided with a belt set around rollers, which carries the optical disc in contact with the belt. In the disc changer, the belt is rotated by a gear of the roller, which is engaged with an external drive gear for taking the optical disc through rotating movement. Among the optical discs which have been taken, a target optical disc opposite the slit of the disc control plate passes through the slit, and the other optical discs stop while abutting against the disc control plate. The optical disc which has passed through the slit is inserted into disc carriage rollers, and further carried to the drive for recording/reproducing.

A control device for controlling a vehicle drive device includes a rotary electric machine in a transmission path connecting a combustion engine with wheels; a first friction engagement device between the combustion engine and the rotary machine; and a second friction engagement device between the rotary machine and wheels. The control device shifts the first and second engagement devices from a state in which the first engagement device is disengaged and the second engagement device is in direct engagement so that force is transmitted between the rotary machine and wheels, to a state in which force is transmitted at least between the combustion engine and wheels, by shifting the second engagement device from direct engagement to a slip state and thereafter shifting the first engagement device from disengaged to engaged. After the state is changed, the control device shifts the second engagement device from slip engagement to direct engagement.

The present invention is an image processing apparatus that reconstructs one frame of image data using block-level image data, including a unit that receives the block-level image data to which position information has been added, a unit that determines whether or not there was an error in the transmission of the received position information, a first storage area used for storing the block-level image data corresponding to the position information for which a transmission error did not occur, a second storage area used for storing the block-level image data corresponding to the position information for which a transmission error occurred, a unit that infers correct position information for the block-level image data stored in the second storage area based on the first storage area and the second storage area, and a unit that reconstructs the one frame of image data using the inferred position information.
摘要:
A method of producing a clad sheet formed by joining a clad layer at least containing nickel, chromium, silicon, and phosphorus to a base material made of a stainless steel or a nickel-based alloy. A step of forming the clad layer includes contact-bonding a mixed powder to the base material, wherein an alloy powder that contains at least one selected from chromium, silicon, and phosphorus as components, and a nickel powder that functions as a binder to have the alloy powder be contact bonded to the base material are mixed in the mixed powder.
摘要:
A camera for taking a state behind a vehicle is installed in a position laterally shifted from the rear center of the vehicle. An image processing unit generates a rear image from a camera image by shifting merely a rectangular area of the camera image so that a vertical center line thereof can substantially accord with the center line along the lengthwise direction of the vehicle. Furthermore, processing for correcting lens distortion may be performed. As a result, when the vehicle is moved straight backward, an object present on the center line of the vehicle moves vertically in substantially the center of the screen, so that a user can be prevented from having an odd feeling to see the image.
