A memory for temporarily storing a transmitting signal is provided in association with each channel i.e., each transducer of a probe, a transmitting signal for transmitting an ultrasonic wave of a desired waveform is formed through a computer processing, and the thus formed transmitting signal is stored in each memory. Transmitting signals are sent simultaneously to individual channels from individual memories. This ensures that a transmitting signal of a desired waveform can be applied to each channel and the transmission of an ultrasonic wave can be controlled desirably.

An optical recording system is disclosed in which input pixels are recorded by controlling the quantity of light as a medium based on the input pixels. The information on the pixels surrounding at least given one of the input pixels is compared with predetermined pattern information, and the particular pixel is accordingly subdivided into a plurality of regions for each of which the light quantity is controlled. Specifically, an optical recording system includes a recognition device for recognizing at least one feature of the desired image by comparing pixel information constituting a predetermined pattern with other pixel information making up a recording target and at least a given one of the pixels with surrounding pixels, and a device for determining the light quantity in a predetermined manner in accordance with the feature. The system further includes a light quantity control device including an exposure pattern signal storage having stored therein a set of rules for controlling the light quantity of a given one of the input pixels in accordance with the information on the surrounding pixels.

A main control unit for controlling a dot printing element in a laser beam printer has a first control means for controlling the dot printing element so as to print a predetermined dot size in accordance with an existence of a dot signal in an image information signal. The main control unit has a second control means and a control selection means. The second control means controls the dot printing element so as to vary a size of the dot of a dither matrix. The control selection means operates selectively the first control means and the second control means. A gradation data is transmitted to the printer without conversion of a dither matrix data. The printer can print an image in response to in either cases of a character pattern dot data signal and a gradation data signal. The printer has a gradation signal on an interference, a gradation converting means and a laser modulating means. The printer can connect in either cases of an existence state and a non-existence state of the gradation signal.

摘要:
A combination of a thermal printer and an invertible ribbon cassette has a mechanism for preventing a portion of the inked ribbon extending between a supply core and a take-up core of the ribbon cassette from shifting in the direction perpendicular to the longitudinal direction of the inked ribbon with respect to a printing head. The mechanism includes a substantially planar surface of a platen, and a printing head is urged against the planar surface of the platen through the inked ribbon portion and a sheet to which solid ink in the area on the inked ribbon portion is transferred by the printing head. The width of that area on the inked ribbon portion in the widthwise direction of the inked ribbon is at most equal to a half of the width of the inked ribbon. Alternatively, the mechanism includes a detector mechanism operative in response to the variation in diameter of the inked ribbon wound on the supply core for applying a variable back tension in the reverse direction to the tension acting on the inked ribbon portion by the take-up core.
摘要:
A restriction flange is provided on the inner end of each cylindrical holder in a sliding universal joint to keep the pair of cutouts which are provided for installation of the inner roller aligned with the longitudinal direction of the transmitting groove. The flange can be rectangular having appropriate side lengths to restrict any rotational motion of the cylindrical about it's center axis.
