Abstract: A computerized composing system includes a color transfer unit for selectively coloring portions of the printed output. Initially the operator places an original piece of artwork on an optical scanning digitizer. The digitized image is stored in a computer and displayed on a monitor screen or may be created, on screen, by the operator employing various features of the system software. Letters and numbers are then added to the display screen through a computer keyboard. A mouse or the keyboard can be used to edit the graphic and alphanumeric information on the composition until it is satisfactory to the operator. Therefore, what the operator see on the screen is what the operator gets as a printed result. The composition is then transmitted to a laser printer. A color transfer unit integrated into the printer permits color to be transferred to the toner on the paper stock. A solenoid activated roller forces a web of transfer foil against the printed stock.

Abstract: The potentiometer consists of two halves. Each half has a base plate (5,6) ending in soldering lugs (51,61,62). One part each of a casing (1 or 2) and a rotary driver half (3 or 4, respectively) are molded to each base plate in a plastics injection molding process. The two potentiometer halves are interconnected at their casing parts (1,2), on the one hand, and at their rotary driver halves (3,4), on the other hand, by ultrasonic welding. For this purpose a circumferential thickening (15,47) each is provided of tapering shape. A slider spring (8) on the one hand has slider lobes (81) which slide on a resistor path of a resistor plate (7) and, on the other hand, slider lobes (80) which slide on the base plate (5) opposite the resistor plate (7). Hereby the central or potentiometer tapping is effected electrically at this base plate (5) and the soldering lug (51) connected to the same.

Abstract: A printing apparatus for use in a printer with a photo-sensitive drum. The printing apparatus includes a spotlight source for generating a light provides essentially a point source. A photo-optical converter which is optically coupled to the spotlight source converts the light from the spotlight source to linear rays of light. A plurality of microshutters optically coupled to the photo-optical converter selectively transmits the light at selected portions of the array to the photo-sensitive drum. As a result, a light path is defined from the spot-light source through the photo-optical converter and the microshutters to the photo-sensitive drum.

Abstract: A joystick controller for generating analog signals representative of coordinate positions is characterized by a pair of members movable in orthogonal directions by a handle. Each member carries at least one wiper contact adapted to slide linearly along an associated linearly extending resistor carried on a circuit board to generate the signals representative of coordinate positions. The use of linearly extending resistors for generating the signals, as compared with rotary potentiometers, provides for a reduction in size of the joystick controller, economies in its manufacture, and a high degree of linearity between handle positions and the signals generated.

Abstract: A contactor device of a circuit breaker has a movable contactor to be raised or opened upon the occurrence of a short circuit current. One end portion of the movable contactor is bifurcated to form parallel claw members that engage a rotatable trip latch. When the movable contactor is raised due to a magnetic repelling force generated in the movable contactor and a fixed contactor during a short-circuit condition, the claw portions of the movable contactor are deformed due to a magnetic attractive force and are disengaged from the trip latch. The rotation of the movable contactor is restricted and it returns to the original positional relationship in which the claw members are engaged with the trip latch.

Abstract: The present invention provides a label printer which enables a large amount of information to be printed on a label without being restricted by the memory capacity of an image buffer by printing such information on the label by several successive printing operations. In the label printer, in case the amount of information to be printed on a label exceeds the memory capacity of the image buffer, printing picture image data are divided into several blocks having arbitrary amounts of data and are produced in the image buffer. Every time, a picture image is formed on the label in accordance with the printing picture image data.

Abstract: A dot line printer is releasably connected by a control circuit to the output of a monitor which senses variations or faults in the AC line voltage for a computer or the like. Each time the monitor senses any one of the five different voltage disturbances, the information is transmitted as digital data to the printer, which then produces a continuous strip chart or graphical printout of the voltage variations. The printer advances paper continuously and in small increments, while printing thereon six parallel trace lines that extend in the longitudinal or feed direction of the paper. One trace line represents time, and the remaining lines the zero ordinates for five different voltage faults. Whenever a fault is detected, the associated trace line widens to print a horizontal bar. When a power failure occurs and is thereafter restored, a header (indica line) is printed on the paper before printing of the trace lines resumes. The monitor and printer, if desired, may be operated independently of each other.

Abstract: When a data control portion 300 receives a request for changing a density of picture elements from an external data processing apparatus, a printing control portion 200 defers exposure if it is before start of exposure, until a rotating speed of a polygon mirror 34 becomes constant. If exposure is being performed, the printing control portion 200 defers change of the density of picture elements until the exposure is completed. If printing is being performed in response to a printing request received till then, the printing control portion 200 defers change of the density of the picture elements until the printing is completed. In addition, the printing control portion 200 automatically sets an initial density value of picture elements designated by a printing density initialization switch 237, when power supply is turned on.
