    摘要: A pair of flanges are fixed to a pipe end of a port of a plasma vacuum vessel and another pipe end to be connected thereto. These flanges each have a ring-shaped knife edge. A copper gasket is interposed between the respective knife edges of the two flanges. A predetermined number of bolts are tightened to fix the flanges to each other. As a result, the knife edges bite into the copper gasket, and a linear sealing load from the knife edges acts on the gasket, thereby sealing and isolating the space inside the port from the outside. The number n of bolts are given by3(B+28)/65-0.ltoreq.n.ltoreq.3(B+28)/65+0.02B,and the flange thickness t is given by ##EQU1## where B is the diameter of a circle passing through the respective central axes of the n number of bolts. Thus, the bolt number and the flange thickness are reduced without lowering the sealing performance.

    摘要: A driving apparatus for controlling the drive of a direct current (DC) brushless motor including a stator having a plurality of armature coils which are provided on a generally circular stator yoke, and a rotatable rotor in which a disk-like magnet having N and S poles arranged alternately in a circumferential direction is provided on a generally circular rotor yoke to face the armature coils, includes a speed sensor for producing outputs responsive to a rotation speed of the rotor, a counter for counting the pulses which are produced by the speed sensors, a control circuit responsive to the speed sensors and counter for controlling the current applied to the armature coils in a predetermined sequence to thereby rotate the rotor, and a mechanism for cancelling a load acting on the rotor. The control circuit, at a start-up of the motor, switches the current applied to the armature coils to excite the armature coils in several different phases to thereby locate the rotor at a starting angular position, in the event when the rotor is located at the starting angular position, cancels a load acting on the rotor, at least before a last one of the phases is excited, subsequently controls rotation drive by counting output pulses of the speed sensor to determine an angular position of the rotor, and controls a rotation direction of the rotor on the basis of output pulses of the speed sensor and on a resulting count of the pulses. Also provided is a driving method for a brushless DC motor for effecting such a control.

    摘要: A drive current for driving actuators is generated based on a first digital signal comprising n-bit binary data which is supplied from a microprocessor and it is applied to an excitation coil. The drive current is supplied to the exciting coil and is converted into a voltage which is then converted into a second digital signal comprising n-bit binary data. The binary data of the second digital signal is compared with the digital data of the first digital signal to detect an alarm condition. Furthermore, the second digital signal is compared with first and second reference value to set plural alarm conditions.

    摘要: A method of controlling a cut-sheet feeder installed on a printer to feed a cut sheet from a sheet hopper (1) included in the cut-sheet feeder to the printing unit of the printer at a sheet feeding speed corresponding to that of the printer. The printer gives a correction signal (S.sub.1) of a predetermined pulse width to the cut-sheet feeder, and then the cut-sheet feeder converts the pulse width of the correction signal into a corresponding number of pulses of a clock signal generated by its control unit (25), and obtains the difference between the number of pulses of the clock signal and a predetermined reference value to determine the deviation of the frequency of the clock signal from a reference frequency. The difference between the number of pulses of the clock signal and the reference value is added to a reference motor controlling value for driving a stepping motor (4) at a reference speed to obtain a corrected motor controlling value. When the printer gives a sheet feed command signal (S.sub.f) to the cut-sheet feeder, the stepping motor is driven for rotation according to the corrected motor controlling value.

    摘要: An image-forming apparatus includes a developing roller and a developing blade. The developing blade applies toner to the developing roller to form a thin layer of toner on the developing roller. The image-forming apparatus performs a printing operation that includes a paper-feeding period and a developing period following the paper-feeding period. The developing roller rotates relative to the developing blade at a first speed during the paper-feeding period and then at a lower second speed than during the developing period, thereby eliminating chance of white lines of occurring in a printed image. The developing roller may be rotated at a constant speed in each printing operation until the circumferential surface of the developing roller has traveled over a certain cumulative distance. When the surface has traveled over the first distance, the developing roller may be rotated at an increased speed over a certain distance.

    摘要: A process for forming a light-reflecting bar code on an end disc of photographic film spool is performed by the steps of placing on the end disc of photographic film spool a hot-stamp film comprising, in order, an adhesive layer, a light-reflecting metal layer, a transparent protective layer, a releasing layer, a support film, and a stain-shielding layer formed of material inhibiting migration of a compound having a low molecular weight from the support film (e.g., compound having a siloxane bonding or deposited inorganic oxide) in such manner that the adhesive layer is brought into contact with the end disc, and pressing for 0.1 to 2.0 seconds a stamper having a heated bar code-stamping die, so as to transfer the light-reflecting metal layer onto the end disc in the form of the bar code.

    摘要: A color image recording apparatus operates in a color print mode and in a monochrome printing mode. A set of color print heads are driven in accordance with corresponding color image data. A monochrome print head is driven in accordance with black image data. A controller transmits in parallel or in serial the color image data and the black image data to the corresponding print heads in a color printing mode. The controller transmits the black image data faster in the monochrome printing mode than in the color printing mode, thereby increasing printing speed. The controller may include signal processing circuits such as compressing circuits and expanding circuit for the respective color image data and black image data. In the monochrome printing mode, the controller divides the black image data into a plurality of segments and supplies the segments in parallel to the signal processing circuits. The signal processing circuits process the segments and supply the processed data to the monochrome print head in a predetermined sequence, thereby increasing printing speed.

    摘要: The operation of an automatic sheet feeder provided with a plurality of sheet hoppers which are used selectively to feed sheets to a printer is controlled. A control unit of the printer supplies a multiplex control signal including a hopper select signal and a sheet delivery signal to the automatic sheet feeder through a single signal line. The width of pulses of the hopper select signal is smaller than a predetermined time, while the width of the sheet delivery signal is greater than the predetermiend time. The pulses of the multiplex control signal are compared with the predetermined time to discriminate the hopper select signal and the sheet delivery signal from each other. That sheet hopper corresponding to the number of pulses of the hopper select signal is selected, and then the automatic feeding of sheets from the selected sheet hopper commences upon the reception of the sheet delivery signal.
