摘要： A controller for a dot impact printer has capacitance sensors for sensing the motion of the dot wires in the print head, and a non-volatile, rewritable memory for storing self-adjustment data relating to dot-wire characteristics. A processor controls the driving of the dot wires according to the self-adjustment data stored in the memory. At certain times, the processor causes the dot wires to be driven in a test sequence and updates the self-adjustment data in the memory according to the resulting sensor output. Print quality is thereby maintained for the full guaranteed life of the print head.

摘要： According to a method of adjusting a head gap, a wire dot head is set to a predetermined position of a reference head gap; a printing pattern for detecting printing time is printed by a plurality of pins; reference printing times of respective pins are detected. Next, a test printing is performed with test printing dots previously selected from printing data, and printing time of the test printing is detected. Then, the thickness of the printing media is calculated based on the reference printing time and the printing time of the test printing. At that time, a rule of thumb in which the difference of the printing time corresponds to the difference of the head gap, is used. Then, a shift amount of the wire dot head is calculated for setting the head gap to an optimum value according to the thickness of the printing media, and gap shifting mechanism shifts the wire dot head by the shift amount. This leads to highly accurate detection of the head gap and improves printing quality thereof.

摘要： An image-forming apparatus includes a developing roller and a developing blade. The developing blade applies toner to the developing roller to form a thin layer of toner on the developing roller. The image-forming apparatus performs a printing operation that includes a paper-feeding period and a developing period following the paper-feeding period. The developing roller rotates relative to the developing blade at a first speed during the paper-feeding period and then at a lower second speed than during the developing period, thereby eliminating chance of white lines of occurring in a printed image. The developing roller may be rotated at a constant speed in each printing operation until the circumferential surface of the developing roller has traveled over a certain cumulative distance. When the surface has traveled over the first distance, the developing roller may be rotated at an increased speed over a certain distance.

摘要： A connector housing has an insertion slot for receiving a companion base board, a plurality of grooves defined in a housing bottom in a direction normal to the insertion slot, and a plurality of pin attachment holes disposed between the insertion slot and the grooves. Contact pins are approximately L-shaped and pivotally held in the pin attachment holes, respectively, in the vicinity of central bent portions of the contact pins. When the connector housing is attached to a base board and the companion board is inserted in the insertion slot, ends of the contact pins are connected to a circuit pattern on the base board and opposite ends of the contact pins are connected to a circuit pattern on the companion board. The base and companion boards are therefore electrically connected to each other substantially perpendicularly to each other.

摘要： A wire dot printer has a thermistor that detects the temperature of a print head and a counter that starts counting when the detection temperature exceeds an alarm temperature. The printer can be controlled by switching over between normal-printing and reduced-character-printing in which a reduced number of print wires is used. When the detection temperature exceeds the alarm temperature, the printer will first stop and then control the print head in such a way as to reduce the temperature. Once the temperature drops back down below the alarm temperature, the printer will perform reduced-character-printing for a definite period of time based on the length of time from when the temperature exceeded the alarm temperature to when the temperature dropped back down below the alarm temperature. By increasing the length of time in which reduced-character-printing is carried out, the amount of heat given off by the print head decreases. Furthermore, by basing the time over which reduced-character-printing is performed on the length of time that the alarm temperature was exceeded. It is possible to set the reduced-character-printing time to an appropriate length such that the print head does not overheat and throughout is not excessively impaired.

摘要： A wire-dot printing head having a plurality of printing elements each including an armature fixedly holding a printing wire on the free end thereof, a plate spring fixedly holding the armature on the free end thereof, a permanent magnet for attracting the armature to strain the plate spring so that strain energy is stored in the plate spring, and an electromagnet which cancels the magnetism of the permanent magnet when energized to release the armature so that the armature is returned to the free position thereof by the strain energy of the plate spring to advance the printing wire for printing. The plate spring has an operating lug portion which can be bent in either direction from outside, and an adjusting lug portion which is formed integrally with the operating lug portion and is moved in the opposite direction when the operating lug portion is moved in one direction to adjust the position of the base end of the armature so that the strain energy stored in the plate spring is varied.

摘要： A printed chip-on-board substrate is for mounting a high-power semiconductor chip. As a construction for efficiently releasing or dissipating heat to be generated in the semiconductor chip, the printed substrate has a printed interconnected substrate and a metal plate bonded on a back side of the substrate. The printed interconnected substrate is constructed by forming an interconnected layer on a surface of the substrate. At a mount area where the semiconductor chip is to be mounted, an opening is formed reaching the metal plate. The metal plate covers the opening on the side of the back side and is formed with a thickness capable of providing rigidity sufficient to support thereon at least the semiconductor chip to be mounted.
