Title: Method and device for forming colored image
Inventor: ERUNSUTO GIISHIE
IPC: G03G15/01
Filed: 1984-04-25
Abstract: Apparatus and method for producing qualitatively high-grade color images of originals such as copy masters for multi-color or process printing by exposing chromatic material wherein the originals are scanned point-by-point and line-by-line and the color signals thus obtained are converted into color density values for the chromatic material by means of a correction of color and of gradation. The drive values for a color exposure unit which exposes the chromatic material point-wise and line-wise are generated from the color density values using a linearization process. As a result of signal inversion color positive originals can be recorded as color negatives and vice versa. The exposure process can be matched to every chromatic material independently of the nature of the original to be reproduced and the state of the developing process by means of changing the color density values according to an arbitrarily selectable correction function and by means of signal inversion.

Title: Base paper winding method
Inventor: OISHI FUMIO
IPC: B65H18/20
Filed: 1986-04-11
Abstract: PURPOSE:To increase tension in winding and increase the length of a base paper to be wound in a unit diameter, by applying a force opposite to the moving direction of the base paper just before it is wound. CONSTITUTION:A first rotating roller 9 and a second rotating roller rotate counterclockwise and a guide roller is disposed in such a manner that the base paper 1 contacts the second roller 10 at a point S2, the roller 10 being located at this side of the moving direction of the base paper 1 so that a force opposite to the moving direction of the base paper is applied to it. The paper core 11 or a roller 11' is caused to contact the roller 9 at a point S1 and contact the roller 10 at the point S2. Since both the rollers 9, 10 rotate counterclockwise, a force in the moving direction of the base paper 1 is applied to it at the point S1 and a force opposite to the moving direction is applied to it at the point S2, thus high tension is applied to the base paper 1 between the points S1 and S2. Since base paper is wound under the high tension, it cans be wound very tightly.

Title: Automatic gain controller for servo mechanism
Inventor: HONGIYOU TADAHIKO
IPC: G05B13/02
Filed: 1989-03-31
Abstract: PURPOSE:To always keep the gain of a closed loop to a constant characteristic, and to compensate load fluctuation by receiving the output of a differential amplifier, which detects the differential signal between a signal outputted from a first detecting circuit and a signal outputted from a second detecting circuit, and amplifying an error signal according to the output. CONSTITUTION:A detecting reference signal superimposed to the error signal of the closed loop is amplified by a closed loop gain, then detected by a second detecting circuit 4. The differential signal between the signal outputted from the second detecting circuit 4 and the signal outputted from a first detecting circuit 3, which detects the output of a detecting reference signal generating circuit 1 as it is, is detected by a differential amplifier 5, and thus the closed loop gain is detected. When the differential signal is outputted from the differential amplifier 5 to a differentiating circuit, the error signal is amplified according to the closed loop gain. Thus the closed loop gain can be always set to the constant characteristic, and the load fluctuation can be compensated.

Title: Semiconductor device
Inventor: KANEKO KATSUYUKI
IPC: H04B15/00
Filed: 1990-03-29
Abstract: PURPOSE:To interrupt propagation of noise caused in an output circuit into the inside of the semiconductor device and to prevent malfunction by interrupting the transmission of a signal from an input circuit to the inside of the device for a prescribed period from the output start or output change of the output circuit. CONSTITUTION:When a signal rises on an output control signal line 10, a signal on a signal line 12 is logical 0 for a prescribed period, then an output circuit 2 is operated and a signal on an output pin 3 changes. Noise is generated on a power line 6 and a ground line 7 by the operation of the circuit 2 and similar noise is caused in the output of an input circuit 5. Since a delay time of a delay circuit is set so as to include major part of noise appearing at the output of the circuit 5, the noise does not appear on a signal line 9 by a MOSFET8 whose gate is controlled with the signal on the signal line 12. Thus, the switching noise caused in the circuit 2 is not propagated in the inside of the device and malfunction due to noise is prevented.

Abstract: PURPOSE: To transcripe and record signals easily magnetically, by bringing the magnetic face of a magnetic recording medium to be transferred into contact with the magnetic recording medium, where signals are recorded in concaves and convexes, and by applying a magnetic field from the external in the thickness direction of these magnetic recording media.  
     CONSTITUTION: Magnetic face 4 of magnetic recording medium to be transferred is brought into contact with magnetic face 2 of master magnetic recording medium 1, where signals are recorded in concaves and convexes, oppositely. Magnets 5 and 6 are so arranged that their different magnetic poles may be opposite to each other while interposing these magnetic recording media 1 and 3, and an intensive magnetic field is applied to magnetic recording media 1 and 3 in their thickness direction.
