Abstract: A polyamic acid is synthesized by the ring-opening poly-addition reaction using a biphenyl tetracarboxylic acid as a tetracarboxylic acid moiety and an aromatic diamine, particularly p-phenylene diamine, as a diamine moiety. An aromatic polyimide resin layer possessing a highly desirable heat-resisting property as a heat-resistant insulating coating material and excelling in adhesive strength relative to a substrate is obtained by adjusting the polyamic acid in viscosity with a suitable organic solvent, applying the resultant polyamic acid on a substrate, and firing the applied layer of the polyamic acid. The substrate, for example, is a conductor layer formed as with copper and used as a multi-layer wiring board for hybrid IC's.

Abstract: An image printing machine is arranged whereby unnecessary image information, although it is read out by an image scanner, is automatically deleted so as not to be printed on a printing paper. Moreover, the printing position of the read-out image information printed by the image printing machine on the printing paper can be advantageously changed in accordance with the number of times of the image reading.

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.

The f.theta. lens system has first and second lenses arranged, in this order, next to the rotating polygon mirror and on the optical path through which the laser beam is introduced from the rotating polygon mirror to the photosensitive drum. Each of the first and second lenses has light-entering and -emerging faces which are formed in a non-spherical shape.

Resistance value of the resistor are adapted to vary depending upon a magnitude of deformation of the ceramic diaphragm, and thereby represent the pressure applied to the ceramic diaphragm. The ceramic diaphragm and the ceramic base consist of a co-fired body obtained by co-firing an unfired diaphragm member and an unfired base member.

Abstract: This invention concerns an image processing system which is constructed by combining a plurality of image readers each adapted to read an image electrically and produce image data as output and a printing means for producing the image on a recording medium based on the introduced image data. During the course of transfer of an image signal from the image readers to the printing means, the image processing system automatically delays the actuation of the image readers when the mode of prohibiting the transfer of image signal exists, whereas the image processing system automatically actuates the image readers immediately after the mode of prohibiting the transfer of image signal changes to the mode of permitting the transfer.

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.
