    摘要： The present invention discloses a technique of effecting recording on a recording medium by a plurality of recording elements, wherein recording density by the plurality of recording elements is varied. Further, the recording density by the plurality of recording elements is varied in accordance with a time required for electrical transmission of informations to be recorded for definite numbers of scanning lines. For example, when the time required for such electrical transmission is short, the recording is effected by small numbers of the recording elements, while, when the time required for the electrical transmission is long, the recording operation is effected by large numbers of the recording elements, thereby preventing the image quality from lowering.

    摘要： In the transmission of binary image signals obtained by scanning of an original document, a high signal compression ratio without deterioration in image quality is achieved by subjecting the binary image signals to a selective thinning process in which the signals of a run-length within a determined range are converted into signals of a determined length and by subsequently coding thus selectively thinned signals. A further improved signal compression is also established without deterioration of image quality by conducting, prior to the selective thinning process, preliminary processes such as elimination of isolated dots in the image or smoothing in the principal and auxiliary scanning directions. Furthermore signal compression ratios are increased by preparing state signals representing the correlation between the first image signals present on a first scan line and the second image signals present on a second scan line to encode and transmit the first image signals and the state signals, and still to allow regeneration of the second image signals at the reception end.Transmission of signals either with coding of a high compression or with a coding of a higher popularity can also be achieved through simple switching of the coding system.Furthermore there is also provided effective thinning on graphic information which could not be easily handled with the conventional thinning processes.

    摘要： A scale comprising a regular arrangement of optically or magnetically different response characteristics such as light reflection and light diffusion portions or light reflection and absorption portions is attached to a moving object either directly or by way of an intermediate member. The scale can be attached to a motor or the like even after assembling with associated mechanical components, thereby enabling easy measurement of the mode of operation of the motor or similar movable objects. The light beam from the light emitting device is directed to the label media and the reflected light beam is received by a light receiving device to identify the individual object or product based on the label.

    摘要： This invention provides a facsimile transmitter capable, in transmitting the image signals with an image size modified in the principal scanning direction of the original image, of modulating the displacement of the original image in the auxiliary scanning direction in response to the rate of said modification of image size, for example image enlargement.The apparatus is further capable of regulating the displacement in the auxiliary scanning direction inversely proportional to the rate of said modification of image size in the principal scanning direction, further of indicating that said modification is for example an image enlargement, and of showing an intermittently lighted indication for example for an image enlargement during such signal transmission with modified image size in order to facilitate the confirmation of the transmission mode.

    摘要： Characteristic parameters of a torque of a stepping motor and its associated driving current or voltage are measured in advance to providetorque vs. characteristic information data representative of the torque vs. driving current/voltage characterisitcs. Then, the above characteristic parameters are measured again when a real load is applied to a stepping motor as installed with associated mechanical coupling components. An actual load torque is determined by referencing the subsequently measured characteristic parameters to the previously obtained torque vs. characteristic information data. A load inertia moment can be determined by subtracting the motor's rotor inertia moment from a determined inertia moment of the entire system. Efficiency of the motor can be determined by multiplying the output of the measured load torque by the nuber of revolutions per second thereof and dividing this by the power supplied to the motor or driving circuit. Backlash can be determined from the play in the changes of associated current waveforms corresponding to particular intervals, i.e., an interval from when the direction of rotationof the motor is changed to when the load torque increases again.
