Title: Electrophotographic photoreceptor
Inventor: SUZUKI SHINICHI
IPC: G03G5/06
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To obtain an electrophotographic photoreceptor excellent in mechanical properties and having enhanced chemical durability and light resistance without impairing photosensitive characteristics such as electrification ability and sensitivity, coatability, etc., by incorporating a wax having an ester group into the outermost layer of a photosensitive layer and using a compound having a butadiene skeleton as an electric charge transferring agent. SOLUTION: This electrophotographic photoreceptor has a photosensitive layer and the outermost layer of the photosensitive layer contains a wax having an ester group. If the wax content is too low, the wax is not effective to improve mechanical characteristics. If the wax content is too high, the wax deteriorates electrical characteristics and makes the surface of a coating film rugged. When a surface layer is formed, the wax is dissolved in a coating fluid for the surface layer and the coating fluid is applied to form the objective photoreceptor. A compound having a butadiene skeleton used as an electric charge transferring agent in the photosensitive layer has an aromatic group at both ends of the butadiene skeleton and has a heteroatom in the molecule.  A combination of two electric charge transferring agents may be used in consideration of combination with an electric charge generating layer, polarity, etc.

Abstract: PURPOSE:To obviate a line buffer for delaying a picture signal and to attain reduction in cost by reading simultaneously the same read line of an original by each-dimensional image sensor on light beams which are allowed to branch. CONSTITUTION:When a fluorescent lamp 7 is lighted and the surface of an original 111 is irradiated therewith, a reflected light passes through a convergent rod lens array 6 and an I/R cut filter 5 and reaches a half mirror 2, a transmission light 8a which transmits through the half mirror 2 reaches the photodetecting surfaces of CCD(Charge Coupled Device) substrates 3a, 3b, and a reflected light 8b which is reflected reaches the photodetecting surface of a third CCD substrate 3c. That is, a light beam in the same read position of the original 111 is allowed to branch into two directions, reaches simultaneously on the image forming surfaces of a first - third CCD substrates 3a-3c, and accordingly, in output data of each CCD substrate 3a-3c, there is not timing-like deviation. In such a way, a memory for delaying a picture signal can be omitted, and the cost of the device can be reduced.

Title: Power converter
Inventor: MIYAZAKI SEI
IPC: H02P27/06
Filed: 1995-03-02
Abstract: PURPOSE: To suppress the speed variation and DC voltage fluctuation a motor caused by a rapid change of a load, by making the upper limit value of a torque reference of a motor zero immediately after the detection of a rapid decrease of the load, and making the lower limit value zero immediately after the detection of a rapid increase of the load. CONSTITUTION: When a load 6 has decreased rapidly, a speed feedback SP-F increases first. The speed increase at this time is generated as the load, torque before the rapid decrease of the load changes into accelerating torque of the motor due to the rapid decrease of the real load. Accordingly, it is necessary not to output positive-side torque immediately after a rapid decrease of the load is detected. So, it becomes possible to prevent a motor from overspeeding by setting the upper limit value of a torque limit to zero by the use of a rapid load change processing circuit 28 immediately after the detection of a rapid decrease of the load by a rapid load change detecting circuit 27, and preventing acceleration torque from being generated.  This is also identical in the case where the load increases rapidly, and it becomes possible to suppress speed variation at the time of a rapid load change.
