IPC: G03G15/09
Filed: 1989-06-22
Abstract: PURPOSE:To prevent the occurrence of a sleeve ghost and image density deterioration at the time of repetitively using the subject device by forming such a layer incorporated with fine particles as the electrical conductivity fine particles and oxide semiconductor fine particles which are small in triboelectrification with respect to a developer are dispersed in a resin and a part of them is exposed on the surface of a developer carrier. CONSTITUTION:The developer carrier 14 inside which a magnet 15 is arranged is constituted so that a resin layer 18 incorporated with fine particles is formed on the surface of an electrical conductivity developer carrying member 17. The resin layer 18 incorporated with fine particles is formed in such a way that the electrical conductivity fine particles and the oxide semiconductor fine particles which are small in triboelectrification with respect to the developer are dispersed in the resin and at least one part of these particles are exposed on the surface of the layer. Thus, by using the electrical conductivity fine particles which make the charges of fine particles leak and an oxide semiconductor which is extremely small in electric charges imparting effect on toner, toner triboelectricity necessary for development is obtained and the sleeve ghost is more effectively reduced.

Title: Data processing system
Inventor: TAKAKURA MITSUO
IPC: G06F5/06
Filed: 1981-10-07
Abstract: PURPOSE:To prevent the same output device from being accessed by plural computers by transmitting data while controlling a line between a buffer device and an I/O device mounted on each computer side. CONSTITUTION:When data are transmitted from an input device 310 to each computer side, a signal 130 opening a gate 3100 is outputted from a bus controller 5. At that time signals 131-13N opening output gates 431-43N in buffer devices 41-4N are not outputted. Consequently input gates 421-42N are opened and data are written in specific addresses in buffer memories 411-41N. When the data are outputted from a buffer device 41 of a computer 1 to an output device 311, for example, signals opening the gates 431 and 3110 respectively are outputted from the controller 5. At that time, the gate 421 of the device 41 is closed and the input gates 422-42N of other buffer devices are opened. Thus the data in the device 41 are transferred to the device 311 and the buffer devices 42-4N.

Title: Metallic thin film magnetic tape
Inventor: SHINOHARA KOUICHI
IPC: G11B5/78
Filed: 1983-08-31
Abstract: PURPOSE:To maintain the short wavelength record preservation characteristics of a magnetic tape even through it is preserved for a long period in a wide range of temperatures of low and high levels, by providing a magnetic recording layer made of a ferromagnetic metallic thin film on a single side of a polymer substrate together with a soft magnetic layer formed on the other side of the substrate. CONSTITUTION:A magnetic recording layer 6 is formed with a ferromagnetic metallic thin film on a polymer substrate 5, and a protecting layer 7 is formed on the layer 6. At the same time, a soft magnetic layer 8 is formed on the other side of the substrate 5. Thus a metallic thin film magnetic tape is obtained. The layer 7 has about 100Angstrom  thickness at most in order to reduce the spacing loss with the short wavelength recording, and the average roughness of the layer 6 is set at about <=100Angstrom . As a result, both layers 6 and 8 are set adjacent to each other in a range of about 200Angstrom -1,000Angstrom  and therefore a leakage magnetic flux given from the layer 6 by a record pattern is closed by the layer 8. This increases the energy stability and improves the demagnetization when the magnetic tape is preserved.

Title: Batch copying device for plural originals
Inventor: TAGAWA TOSHIYA
IPC: G03G15/043
Filed: 1993-06-29
Abstract: PURPOSE:To make it possible to collectively form images for plural originals on a sheet of transfer paper without reading an white original when the number of originals is less than a prescribed number by forming an image even when the read number of originals does not coincide with the set number of originals when no original is detected. CONSTITUTION:An operation part 611 sets up a summarization mode and a user sets up the number of original images to be formed on a sheet of transfer paper and sets up information indicating the summarized number of copies in a counter. A 1st set original is scanned by a scanner control circuit 612 and stored in a prescribed area of a page memory 620 and '1' is added to the counter for the summarized number of originals. When the number of originals is reached to a set number by repeating the operation, images corresponding to a sheet of transfer paper which are stored in the memory are outputted. At the time of detecting an original end during the period of scanning, stored images are similarly outputted. Even when the number of originals is less than a prescribed summarized number, working efficiency is improved without requiring the reading of a white original.

Abstract: PURPOSE:To allow the wind to reach to a wide range by applying nodding motions in both up-and-down and left-and-right directions to blades and a main motor rotating the blades. CONSTITUTION:The rotating speed of a motor 7 for nodding in left-and-right directions and with a reduction gear is set to a non-integer figure greater than 3 in relation to the rotating speed of a motor 6 for nodding in up-and-down directions and with a reduction gear. When the up-and-down nodding motor 6 is rotated by use of a transfer switch 17, a rotary shaft is rotated, the rotation is transmitted to a crank 12 to nod a support mount 3 in the up and down directions. When the transfer switch is turned to rotate the left-and-right nodding motor 7, the rotation is transmitted to a crank 14 to nod a nodding motor support mount 5 in the left and right directions around an arbor 10, and also a main motor 1 is nodded one rotation against one rotation of the up-and-down nodding motor 6. When both motors 6, 7 with a reduction gear are rotated, the sine curve at the wind center generates a phase difference in relation to each reciprocation of the left-and-right nodding and the wind center becomes an approximate sine curve.
