摘要:
A process discriminating unit allows an optimum converting process among a first magnification processing unit, a second magnification processing unit, a first reduction processing unit, a second reduction processing unit, and a third reduction processing unit to be executed on the basis of a conversion magnification (K), a resolution (D), and an image size. Particularly, each of the second magnification processing unit, first reduction processing unit, and second reduction processing unit magnifies an original image to a virtual image of a dot size obtained by magnifying a target image by 2 or 4 by an interpolation based on a simple repetition by a nearest neighborhood method and, after that, reduces to the target image in which the pixel value is obtained by averaging a plurality of pixels corresponding to one target pixel of the virtual image.

A color image is scanned in the matrix direction by the number of colors calculating unit and the number (A) of colors of different full color pixel values is counted. In this instance, each time the number (A) of colors is counted up, a pallet forming unit sequentially stores the full color pixel values as representative colors into entries and forms a subtractive color pallet. When the number (A) of colors exceeds the number (n) of entries of the subtractive color pallet, a transfer format discriminating unit counts the number (N) of transfer pixels up to the end of one-preceding row and compares a transfer data amount by a full color format with a transfer data amount by a pallet format in the number (N) of transfer pixels, thereby allowing the data transfer by the color format of a smaller one of the transfer data amounts to be executed by a data transfer unit.

An image forming apparatus includes a transport mechanism transporting a recording medium on a belt which is transported at a constant speed in a transport direction, a plurality of electrostatic recording units arranged in the transport direction of the recording medium and transferring toner images of different colors, a positional error detecting part using the toner image of a reference color transferred by one of the electrostatic recording units as a reference image, and relatively detecting positional error information related to positional errors of the toner images of remaining colors transferred by the remaining electrostatic recording units with respect to the reference image, and a positional error correcting part relatively correcting the positional errors of the toner images transferred by the remaining electrostatic recording units based on the positional error information. The positional error detecting part includes a part for controlling the electrostatic recording units to transfer at least two resist marks on the belt at a scan starting end and a scan terminating end of the belt in a main scan direction which is perpendicular to the transport direction of the recording medium, with respect to each of the colors, and a second part, including a sensor detecting the resist marks, for detecting positional error quantities of the resist marks of each of the remaining colors with respect to the resist marks of the reference color based on detection times of the resist marks of reference color and the remaining colors.

A relay device for relaying transfer data to be transmitted between the devices has a plurality of testers. Each of the testers determines whether received transfer data is normal or not, and discards the transfer data that is determined abnormal. The relay device also has a counter that counts a number of transfer data discarded by each of the testers respectively, and a determiner that determines whether an operation of each tester is normal or not based on the number of discarded transfer data counted by the counter.
摘要:
A synchronization control circuit applicable to a TDMA (Time Division Multiple Access) digital mobile communication system for controlling the transmission and reception time base of a mobile station on which the circuit is mounted. The synchronization control circuit includes a plurality of time base counter circuits each counting down standard clock pulses to generate a plurality of timing pulse sequences having time bases which are respectively associated with the cells of the system. All the time base counter circuits share a single counter controller which controls the writing and reading of counts out of the time base counter circuits. The counter controller selectively produces the outputs of one of the time base counter circuits as a timing pulse sequence. The synchronization control circuit, therefore, is small size and light weight and saves power.

摘要:
A cooling structure in a cylinder head of a water-cooled multicylinder engine has partitions disposed between cylinders and in a water jacket defined in the cylinder head, cooling inlet ports disposed on one side of plug insertion tubes extending vertically and disposed above substantially central portions of the cylinders and a cooling water discharge port disposed on the other side of the plug insertion tubes, and walls projecting from the partitions toward the plug insertion tubes. Each of the walls includes a lower projecting portion having a relatively small width near a wall of the cylinder head above a combustion chamber defined in each of the cylinders and an upper projecting portion having a relatively large width.
摘要:
A speech processor having microprocessor control of the amplitude level of input speech signals. Input speech signals are applied to a digitally controlled level regulator, the output of which is converted into a digital speech signal for further speech processing. The peak level of the digital speech signals over a frame period is compared in the microprocessor with a preset optimum range. If the peak level falls outside the optimum range, control signals for the level regulator are adjusted in a direction to change the amplification/attenuation amount of the level regulator to bring the peak level within the optimum range.
