Abstract: PURPOSE:To facilitate the easy offset of phase fluctuation in a highly accurate and stable way, by offsetting and eliminating the long-period component of the phase fluctuation the digital or analog frequency received during the propagation on a transmission line at the receiver side. CONSTITUTION:An input signal having the phase fluctuation received under the propagation on a transmission line to a static satellite is supplied through a terminal 1 to be transmitted to a phase controller 4 in the form of a clock signal with the short-period component eliminated or suppressed. The clock signal supplied to the side of a sawtooth wave converter 6 from a voltage controlling oscillator 3 is converted into the sawtooth wave voltage and fed to a sampling circuit 8. The sawtooth wave voltage is sampled at the circuit 8 by the reference clock given from a clock signal generator 7 and then coded to be delivered to an interpolator 10. The interpolator 10 calculates the differential component successively whenever a coded signal is inputted and applies an external interpolation to the differential component to send it to a phase controller 4. Then the phase of the output of the oscillator 3 is successively controlled in the direction where the change component of the interpolation signal is offset and eliminated, and the controlled phase is sent to an output terminal 5.

Title: Automatic focus draw-in device
Inventor: AOI SHIGERU
IPC: G02B7/28
Filed: 1983-01-31
Abstract: PURPOSE:To draw in automatically the focal point while closing an automatic focus control loop and at the same time to move away an objective lens, by adding the voltage to the input of an automatic focus actuator driving circuit only when the objective lens is drawn into the automatic focus. CONSTITUTION:The voltage V0 is needed to obtain a balance between an objective lens and the gravity in the case of an actuator 112 having no spring to support the objective lens. The lens is moved away from a disk if the voltage supplied to an objective lens driving amplifier 111 is higher than the voltage V0. Then a bias generating circuit 115 delivers the bias voltage V2 when the objective lens is drawn into the focus position. Thus the objective lens gets close to the disk and drawn into the automatic focus when it crosses the voltage V0. This state is detected by a comparator 116, and the output of the circuit 115 is reset to the voltage V1 (needed to move the lens away from the disk). The lens is drawn again into the automatic focus if the voltage of the amplifier 111 is less than the voltage V0 in case the light cutting time is short and the light is restored.

Filed: 1987-01-22
Abstract: PURPOSE:To perform control so that a tack value is within a range as proper as possible, by measuring the quantity of torque or strain applied to an ink roller and controlling the number of rotations of an ink roller so as to keep the measured value constant. CONSTITUTION:After the operation of a printing apparatus is started, ink rollers A, B rotate at constant rotational frequency N for a definite time by a timer. Thereafter, the torque applied to the ink roller A is measured by a torque meter 11 and the measured value is inputted to a rotational frequency control apparatus 12. Then, the torque applied to the ink roller A is sampled at every definite time. When the torque value measured at this time is larger by a set value or more than the torque value sampled at the previous time, the output of a motor 3 is suppressed to reduce the rotational frequency of the ink roller A and, when said torque value is the set value or less, the rotational frequency is returned to N. By reducing the rotational frequency, the increase in torque (increase in tack) can be suppressed and the sharp increase in a tack value is prevented and control is performed so that the tack value is within a proper range for a long time.

Title: Gradation recording system
Inventor: MOBARA YASUHISA
IPC: G06F3/12
Filed: 1987-01-22
Abstract: PURPOSE:To smooth the output of an oblique line, by a method wherein a noticeable pixel is compared with the circumferential pixel thereof to detect that said noticeable pixel is the edge part of the oblique line and set to the optimum black pixel arrangement pattern. CONSTITUTION:An input image signal is stored in a three-line buffer 7 in such a state that positional relation is held. At this time, the density level signals in this 3X3 matrix are simultaneously sent to an oblique line part detecting part 8 and, in this case, an E-position becomes a noticeable pixel and, for example, when F and H are the blackest level and A, B and D are the whitest level, a pattern is outputted as the output of the noticeable pixel E from a black pixel arrangement pattern generating part 9. For example, when the black pixel pattern generating part 9 develops 16 gradations as binary density patterns, density patterns a-1-16 are developed corresponding to the circumferential density value. Since a black pixel is concentrated according to the circumferential density pattern, each pixel becomes the shape approximate to that of an input image and an oblique line part is smoothly expressed.

Abstract: PURPOSE:To form a sharp image superior in powder characteristics by executing an operation for removing a part of surfactant adhered to produced microcapsules and reducing an amt. of surfactant to a specified percentage or less of the total weight of the capsulated toner. CONSTITUTION:A surfactant used in a step for producing microcapsules in an aq. medium tends to adhere to the produced microcapsules in a considerable amt. The capsulated toner obtained by separating them in an adhered state from the aq. medium and drying them scarcely obtain satisfactory powder characteristics, and their electric resistance and chargeability are readily affected by environmental conditions, such as temp. and humidity. The capsulated toner superior in the powder characteristics, etc. are obtained by lowering an amt. of surfactant to <=1wt%. To produce the capsulated toner small in an amt. of surfactant adhered to them, it is desirable to wash the produced microcapsules once or in several times with a solvent, such as water, and remove them adhered to the surfaces of the outer shells to an extent as small as possible, and then to subject them to a drying treatment, such as spray drying.
