Abstract:
A relay apparatus (relay unit) is provided between a PC, from which image data is transmitted, and an image recording apparatus (image recording unit). The relay apparatus executes a process for correcting a color on the image data transmitted from the PC to the image recording apparatus. In addition, a storage unit of the relay apparatus stores unique information of the image recording apparatus, such as a production number. The relay apparatus executes processes for correcting the image data and for adding the unique information to the image data transmitted from the PC, and then transmits the processed image data to the image recording apparatus. Thus, realized is an image recording system and the relay apparatus, in which it is not necessary to provide a circuit which executes a process for embedding unique information in the image data in the image recording apparatus, so that deterioration in quality of the image caused by the unique information can be prevented as much as possible.

Abstract:
Sufficient pressure is produced in a pocket of a hydrostatic bearing when a corresponding cylinder is about to switch from a suction stroke to a discharge stroke in order to prevent solid contact of sliding faces. A plurality of cylinders are arranged on a circle around a center axis of a cylinder block rotatably supported in a housing. Pistons reciprocates in the respective cylinders. A suction port and a discharge port provided to the housing selectively communicate with the respective cylinders in accordance with a rotational position of the cylinder block. A drive shaft inclined relative to the center axis of the cylinder block, a rotation transmitting mechanism for transmitting rotation of the drive shaft to the cylinder block for rotating the cylinder block synchronously with the drive shaft, and a rotating disk rotating together with the drive shaft and cooperatively engaged with the pistons are further provided. A fixed sliding contact face is formed in the housing to have a sliding contact with a rear face of the rotating disk. Pressure pockets are formed on the rear face of the rotating disk in correspondence with positions of the respective pistons. Pressure paths for conducting hydraulic pressure in the respective cylinders to the respective pressure pockets via the pistons are further provided. There is further provided a pressure introducing mechanism for introducing a high pressure fluid to a pocket moving along the fixed sliding contact face along with the rotating disk at a position in which a corresponding cylinder is about to switch from a suction stroke to a discharge stroke.
Abstract:
A numeric control device of a turning mechanism which turns a turning body from a driving source which circularly moves through a non-linear transmitting mechanism has a coordinate transformation device outputting a signal which converts an inputted turning angular signal into a position of the driving source, and a compensator outputting a signal which is derived from computing a positional error of the driving source in accordance with the turning angular signal, and the control of the driving source is carried out by a servo-input signal which is derived from the sum of a conversion signal outputted from the coordinate transformation device and a compensation signal outputted from the compensator. Since the numerical control mechanism of the present invention controls the driving source with addition of the compensation signal, it becomes possible to stabilize the turning velocity of the turning body with high accuracy.
