Title: High voltage source for sopying machine
Inventor: TAKAHASHI TSUNEHIDE
IPC: G03G21/00
Filed: 1984-08-03
Abstract: PURPOSE:To obtain a small-size high voltage source in a single power source structure, with no deterioration of a photosensitive medium, free from the generation of a large amount of ozone and excellent in reliability, by taking out a bias voltage with application of a voltage below a discharge start voltage even if a transfer charge trigger signal is ''off''. CONSTITUTION:A transistor Q2 is driven at an oscillation frequency, which is determined by an external resistor R14 and a capacitor C5 for a switching regulator IC. A high voltage pulse which is generated on the secondary side of a transformer TR3 is smoothed by a diode D5 and a capacitor 6 to obtain a high DC voltage. A load current between output terminals T and B is detected by a variable resistor VR3 and compared in a comparator with the reference voltage. The pulse width varied according to the result of the comparison, whereby the output current is controlled to a constant level. When a transfer charge trigger input or a bias trigger signal goes to a normal level, a photocoupler P1 or P2 is turned on, the reference voltage in the IC and a reference voltage as a division voltage from a voltage divider consisting of resistors R4 and R5 or resistors R6 and R7 are fed as inverted inputs to the comparator, which provides a current according to the values of the inputs.

Title: Preparation of electrophotographic developing carrier
Inventor: KOBAYASHI HIROYUKI
IPC: G03G9/113
Filed: 1980-11-19
Abstract: PURPOSE:To prevent toner from being pulverized to a fine powder and attaching to a carrier surface, etc. especially in the magnetic brush development method, and to always obtain a superior image, by mixing resin coated carrier particles with a fine hard powder to bring both into full contact and to form a rugged rough surface on each particle. CONSTITUTION:Carrier particles obtained by coating the reduced iron powder surface with polyvinyl fluoride or the like resin and a fine hard powder, such as diamond dust or silicon carbide in an equal mixing weight ratio are mixed and brought into full contact for a proper treatment time. The resultant mixture is sucked in a strong magnetic field to separate only the fine hard powder, leaving the coated carrier particles with rugged surfaces in the magnetic field. These carrier particles and a toner are well mixed to form a developer for use in a magnetic brush developing device, thus permitting an always sharp, high contrast superior electrophotographic image free from rubbed parts or uneven parts.

Title: Sheet material carrying device and image reader and image forming device
Inventor: NISHINOHARA TAKAYUKI
IPC: H04N1/04
Filed: 1999-06-09
Abstract: PROBLEM TO BE SOLVED: To prevent the difference of carrying directional length of a reading image in a releasing state from a separating roller of a separating piece by providing a control means for controlling a driving speed of a driving means according to an operation state of a friction releasing means. SOLUTION: Output from a photosensor 907 being a detecting means to a separating piece releasing lever is numerically expressed by an A/D converting circuit to be bent to a control part 900. A CPU of the control part 900 discriminates whether or not a separating piece is put in a state of separating from a separating roller from this output. At image reading time of a document, when the separating piece is not released, a rotating speed of a motor M is controlled so as to increase more than when the separating piece is released. Thus, a document carrying speed on a reading line at separating piece released time and unreleased time becomes the same to thereby prevent the situation where the longitudinal directional length of a read image becomes different at separating piece released time and separating piece unreleased time.
