Title: Telautogram information reader
Inventor: FUWA JIYOUICHI
IPC: G03G15/04
Filed: 1984-03-19
Abstract: PURPOSE:To perform both the detection of a reading range and the picture reading process with the scan of just one time by separating a photodetecting element for detection of original position from an image sensor for image reading to set the photodetecting element at a position shifted in the subscanning direction and therefore monitoring the subscanning position always preceding the image sensor by said photodetecting element. CONSTITUTION:An input terminal of one side of an analog comparator CP3 is connected to an output signal line Vc1 of a subsensor SES. While the reference voltage Vr3 is applied to the other input terminal of the CP3. The voltage Vr3 is set at such a level that can discriminate the level Vc1 of the SES when the SES receives the direct light from a lamp LPX and does not. A subscan motor M7 is controlled by a subscan control circuit 120 via a motor driver 130. An image read control circuit 100 controls a main scan control circuit 110, the circuit 120, etc. The circuit 100 refers to binary signals Va and Vc2 sent from analog comparators CP2 and CP3 and identifies the size and the position of an original.

Filed: 1990-03-05
Abstract: PURPOSE:To devise the title device such that the offset of a radial error signal hardly takes place by providing a luminous flux separation element separating luminous flux in a reflected light and two photodetectors receiving separated reflection luminous fluxes separately. CONSTITUTION:A luminous flux separation element 20 is arranged in a reflecting luminous flux 15 is parallel with a projecting direction of an information track on a disk 4 so as to split a luminous flux along with a straight line passing through the center of the luminous flux, and two photodetectors 21, 22 receiving the reflecting luminous flux 15 split by the luminous flux separation element 20 respectively are arranged at a position in conjugation with a laser light source 1. That is, the separation of the luminous flux required to generate a radial error signal is implemented at not a conjugation point with the laser light source 1 but at a position having a larger luminous flux diameter than that at the conjugation point by arranging the luminous flux separation element 20 in the reflection luminous flux 15. Even when relative deviation between the photodetectors 21, 22 and spots 10a, 10b takes place, the offset of a radial error signal 14 is not caused.

Abstract: PURPOSE:To prevent uncontrollable sticking of ink to printing paper and discharge printed paper to a discharging direction without fail by arranging part of an ink ribbon outside the width of printing paper and holding part of the paper in a paper channel with a platen and a paper guide during the discharge operation of the paper. CONSTITUTION:If printing operation is terminated, CPU drives a stepping motor 25 for driving a carriage, causing the carriage 6 to move toward a paper holding position. When a rotation corresponding to the number of steps is given as prearranged, the stepping motor 25 for driving the carriage stops, resulting in the setting of a paper guide 15 for the carriage 6 in an opposite position to a post card 3a. At the same time, an ink ribbon 18 is held in a position not opposed to the post card 3a. Later, CPU 20 drives a stepping motor 26 for driving a platen, rotating the platen 2 toward a paper discharging direction. Consequently, the post card 3a is properly pressed against the platen 2 by means of the paper guide 15 under an appropriate friction force, being discharged toward a direction above a frame 1.

Abstract: PROBLEM TO BE SOLVED: To actualize high-precision circuit simulation by connecting a circuit wherein a capacitor and an RF output resistance having a time constant for representing an RF output are connected in series between the drain and source and varying the RF output resistance with the gate voltage of the FET. SOLUTION: The circuit wherein the capacitor Crf and RF output resistance Rc having the time constant for representing the RF output are connected in series is connected between the drain and source and the RF output resistance Rc is varied with the gate voltage of the FET. Namely, the RF output resistance Rc which varies with the gate voltage is represented as Rc=Rco/([tanh δ(Vgs-Vrco)}+1]/2), where Vgs is the gate-source voltage, Rco the source- drain resistance at an operation point, Vrco Vgs when Rc begins to increase, and δ the gradient of Rc to Vgs when Rc begins to increase. Consequently, RF characteristics of the FET can precisely be modeled by using this designing method, so high-precision circuit simulation is actualized.

IPC: H01L21/52
Filed: 1988-03-09
Abstract: PURPOSE:To form the structure for the title element into such a free form that the plane of the structure is a square or the like other than a circular form and to contrive the improvement of a space factor at the time of incorporation of the element into a device by a method wherein a flexible or elastic insulating resin is used instead of a metallic bellows. CONSTITUTION:In an element of a flat type structure for dealing with a large capacity, two sheets of metal plates 12 and 14, which respectively come into contact to an anode and a cathode of a semiconductor element 10, are constituted of a metallic material having a thermal expansion coefficient close to that of the element 10 for inhibiting the effect of a thermal stress due to heat generation at the time of operation of a large current. A flexible or elastic material is used as an insulating resin 16 sealing the peripheral part between the plates 12 and 14. Accordingly, as upper and lower flexures due to a pressure welding force F at the time of assembly of the element of a flat type structure can be absorbed effectively, a metallic bellows 8 can be omitted. Thereby, the manufacture of the element of a square flat type structure becomes possible and a space factor at the time of incorporation of the element into a device is improved.

Title: Color synchronizing device of reproduced signal
Inventor: AKIYAMA TOORU
IPC: H04N9/85
Filed: 1984-03-21
Abstract: PURPOSE:To stabilize and increase color loop gains at the time of external synchronizing mode by causing a phase difference of the 1st control means to include more high-band components, compared with those in the off state of the 2nd control means. CONSTITUTION:Loop filters 23a and 23b are provided on a PLL circuit 2, and a cut-off frequency fc of the filter 23a is made larger than that of the filter 23b. Each of outputs of the filters 23a and 23b is selected by an external/internal synchronizing change-over switch 25, and the output of the filter 23a is selected in an external synchronizing mode. Since the filter 23a is selected at the moment the operation is shifted to the external synchronizing mode, the circuit 2 responds also to a high-band component of a color burst phase variation of a reproduced video signal. Thus a phase delay in a band of a color loop due to a proportional control is eliminated, and gains of the color loop can be increased stably.
