    摘要: A device for preventing laser beam leakage, which excludes a danger that a laser beam emitted from a laser source directly attacks eyes of an operator when an external connector is connected to or disconnected from an internal connector, aiming at being inexpensive and excellent in operability, and having a high safety. When the external connector has been removed from the optical transmission apparatus, a pair of movable shield plates are constantly urged in respective directions for closing a receiving opening of the apparatus to bring joining portions of the movable shield plates into close contact with each other, thereby preventing dust from entering the inside of the apparatus and the laser beam from being leaked. Further, a limit switch is provided, which stops delivering an ON signal to an E/O laser module when the external connector is pulled out of the optical transmission apparatus, whereby the E/O laser beam stops supply of the laser beam, thereby bringing into effect a perfect measure for protection of the eyes of the operation from the laser beam.

    摘要: A developing device for an image forming apparatus and using a one component type developer. The developer is transferred from a developer supply member to a developer carrier which are so rotated as to move in the same direction at a position where they contact each other. This prevents the developer from a toner storing section from directly reaching part of the developer carrier having moved away from the contact position despite the movement of the developer supply member. Conductive portions connected to ground and dielectric portions each having a small area are distributed regularly or irregularly on the surface of the developer carrier. Such a surface of the developer carrier is charged by friction by the developer supply member with the result that a great number of microfields are formed in the vicinity of the developer carrier. The microfields allow only the developer sufficiently charged by friction at the contact position to form multiple layers on the surface of the developer carrier. Consequently, the toner with a desired amount of charge and containing a minimum of uncharged toner can form multiple layers on the developer carrier and is transferred to an image carrier.

    摘要: A discrete cosine transformation processor subjects a plurality of input data to addition or subtraction at an adder/subtracter with two combinations according to the control signal every clock pulse so as to output a plurality of combination data. The combination data are assigned to eight groups according to certain combinations and each of them is input to one of eight selection circuits. The selection circuit selects one data from the combination input data according to the control signal and outputs the selected data every clock pulse. A multiplier receives the data selected by the selection circuit and multiplies it by a predetermined coefficient every clock pulse. Further, a second adder/subtracter subjects the output data from the multiplier to addition or subtraction in different combinations according to the control signal to determine cosine transformation coefficient to inverse cosine transformation coefficients.

    摘要: A group II-VI epitaxial layer grown on a (111) silicon substrate has a lattice mismatch which is minimized, as between the group II-VI epitaxial layer and the silicon substrate. The grown group II-VI epitaxial layer also has a (111) plane at the interface with the substrate, and a 30.degree. in-plane rotation slip is formed at the interface between the (111) silicon substrate and the group II-VI epitaxial layer. The above structure is produced by a metal organic chemical vapor deposition method (MOCVD), in which a mol ratio of a group VI gas source supply to a group II gas source supply is kept greater than 15 during the growth. The (111) silicon substrate is preferably mis-oriented toward the direction of the silicon substrate. When a HgCdTe layer is grown on the epitaxial layer, the product thus formed has utility as a monolithic infrared detector in which a plurality of detector elements are formed in the HgCdTe layer and a signal processing circuit is formed in the silicon substrate.
