摘要:
An interface system for a copying system, wherein a frame of transmission data employing a serial communication between a copying machine main body and peripheral devices thereof comprises an address block, a data block and a checksum data block, an optional device corresponding to an address transmitted from the main body transfers data to the main body when the data received coincides with checksum data obtained in the device based on the received data and the transfer of the data is complete when the main body confirms that the transmission address coincides with the transferred data, and when the transferred data is not returned from the optional device or the coincidence is not confirmed, it is determined that a transmission error occurs and data is transmitted from the main body again, whereby reliability of transmission is improved.
摘要:
A digital image forming equipment in which image is formed by reflecting and scanning laser light emitted from a source of light onto a photo-sensitive body by means of a polygon mirror driven and rotated by a drive motor, so composed that the rotation of the polygon motor can be started when operating the operating portions installed thereon and can be stopped in the elapse of a specified period of time after the image forming operation is terminated, and a digital image forming equipment so composed that the drive motor can be started by detecting existence of an operator when the operator approaches the image forming equipment and can be stopped in the elapse of a specified period of time after the image forming operation is terminated.
摘要:
An image processing apparatus wherein a document on a document support table and an optical system are moved relative to each other for scanning to read the image of the document as a density signal, and the read signal is processed as required, the apparatus comprising a document mat so colored that when the document support table is covered with the mat, the read signal represents an intermediate color, discriminating device for judging whether the density signal represents the intermediate color to produce a binary signal, a memory having a memory capacity of l/n based on the density signal, a write control for causing the binary signal to be written in the memory device in synchronism with the scanning movement, and apparatus for determining the size of the document from the contents of the memory device.
摘要:
A sheet material (4) for use in cultivating plants comprising a body having a coilable flexible, fluid-permeable structure and a plurality of passages (7,9) formed in and extending from one surface (3) to the another (5) of said body. The passages serve to induce root tips to grow and contain fertilizers. The body has at least one surface formed with projections and/or recesses. Preferably, the surface having projections and/or is provided with a ceramic powder discharging infrared rays of wavelength in the range of about 5 to 15 micrometers, a elution-rate controlling growth regulation fertilizer and a small amount of a chosen element. In use, a given length of the sheet material is wrapped around the plant.
摘要:
A therapeutic and/or prophylactic agent for viral infection, particularly human immunodeficiency virus (HIV) infection, which comprises as an active ingredient a lactam compound represented by formula (I) ##STR1## wherein X represents --COOR, wherein R represents a hydrogen atom or a straight-chain or branched-chain alkyl group having from 1 to 8 carbon atoms, or ##STR2## wherein n represents an integer of 2 or 3 and A represents methine when n is 2 or a quarternary carbon atom when n is 3, or a pharmaceutically acceptable salt or ester derivative thereof.
摘要:
A multicolor image forming apparatus having a plurality of developing units respectively containing different color developers; comprising a newly selected developing unit switching timing controller for controlling the rotation of the photoreceptor and the timing for switching of the newly selected developing unit, or a previously selected developing unit switching timing controller for controlling the rotation of the photoreceptor and the switching timing of the previously selected developing unit.
摘要:
When forming an image on both sides of set number of sheets of paper, excess paper which remains in an intermediate tray caused by an overlapped feeding of the paper is guided into a bin which has not been in use for the image forming of the above set number of sheet. Further, when some sheets of the paper discharged from the intermediate tray are transferred in an overlapped condition and the paper in the intermediate tray becomes insufficient, the image forming operation corresponding to the insufficient number of sheet of the paper is discontinued, and the sorting operation for the next original starts from a sort bin skipping over some sort bins which should have received the uncopied paper because of overlapped feeding.
摘要:
A device for controlling the charge area of a photoreceptor comprising a detector for detecting the length of a sheet of copying paper, another detector for detecting the length of an image projected area of the photoreceptor, a selecting device for selecting the shorter one between the detected length of the copying paper sheet and that of the image projected area by comparing them with each other, and controls for controlling the charging time of the main charger so as to charge the photoreceptor to an area corresponding to a length selected by the selecting device, whereby the charge area of the photoreceptor is properly controlled so as to correspond to an area necessary to be transferred, even when the length of the image projected area on the photoreceptor differs from that of the copying paper sheet.
摘要:
A lighting control method and an apparatus thereof which determine during the returning motion of the light source, whether the next paper is fed to the registration roller, and if it is determined that the paper is fed, the light source is caused to turn on from the point of the determination, thereby causing the going motion for the next image forming operation without causing to stay the light source at the home position.
