Title: Method for adjusting focus at scanning and recording of picture
Inventor: YOSHIMOTO TAKESHI
IPC: H04N1/06
Filed: 1983-03-01
Abstract: PURPOSE:To adjust an image forming point of scanning luminous flux within the depth of focus of a lens at all times by feeding back the amount of change of a drum diameter stored in advance to an image forming lens thereby moving the lens to correct the position of the lens. CONSTITUTION:An amount of change (y) in the direction of normal of a diameter of a recording drum 2 obtained from a micrometer 28 and an amount of change y' in the direction of normal of the diameter of the drum attended with a temperature change are stored in advance in an ROM22. A CPU21 reads and corrects the amounts of changes y, y' from the ROM22 based on the temperature obtained by a temperature sensor 27 and the result is stored in an RAM23. Position information is formed by the amount of movement of a moving stand 8 in the arrow 7 and from the amount of revolution of the drum 2, the information is inputted to an address counter 26 and a data in the RAM23 is read every moment from the output value of the counter 26. Thus, a motor 12 is controlled via a lens drive interface 29 thereby moving the image forming lens 10 to focus an image on a film 3.

Filed: 1982-03-02
Abstract: PURPOSE:To increase gm and thus contrive the reduction into low noises, by shortening the gate length of a JFET, utilizing an Si3N4 film. CONSTITUTION:After an N epitaxial layer 2 on a P type Si substrate 1 is isolated by P<+> layers 3 resulting in the formation of N type source and drain 7 and 8, a window 11 of the size W2 is opened on an SiO2 film 4 and filled with the Si3N4 12. Next, an island-shaped Si3N4 layer 13 of W2>W1 is selectively formed, accordingly clearances 14 and 15 are formed, and it is etched by hot phosphoric acid into the formation of an island 16 of W3<W1. After oxidation, the Si3N4 layer 16 is removed by etching again with hot phosphoric acid. A P type gate layer 18 is formed by the thermal diffusion from the obtained window 17, and an Al wiring is performed resulting in completion. By this constitution, since the gate length of the JFET can be formed remarkably short, gm can be increased, and accordingly noises can be reduced.

Title: Color solid state pickup device
Inventor: TANAKA OOMICHI
IPC: H04N9/04
Filed: 1979-03-20
Abstract: PURPOSE:To secure the correction to the white balance in a simple constitution by adding the modulation signal of the carrier chrominance signal which gave the change to the liminance signal every 1H-period to the signal converted into the carrier frequency and then carrying out the phase control of the 1H-period. CONSTITUTION:For the color camera in which the mosaic filter is installed in front of solid state pickup device 201, the sequential modulation chrominance signals which are contained in the output of element 201 and vary every 1H-period are converted into the carrier frequency via the horizontal driving frequency of element 201 and by means of frequency converter circuit 209. Then the modulation signal of the carrier chrominance signal which gave the change to the luminance signal every 1H-period and is sent from LPF203 is added to the converted signal. This added signal then receives the phase control with the signals which are and aren't made to pass through 1H-period delay line 213 and then receives mixture 217. As a result, the white balance can be corrected in a simple circuit constitution.

Filed: 1982-03-02
Abstract: PURPOSE:To attain to stabilize the rotation of a rotor operated in a pressure atmosphere varied corresponding to the rotary speed of a rotor main body and to suppress the vibration thereof. CONSTITUTION:A rotor apparatus is constituted from a bottomed cylindrical container 2, a rotor main body 3, a lid body 4, a magnetic bearing 5, a molecular pump 8 fixed to the inner peripheral surface of a side wall 7 opposed to the upper part of a peripheral surface 6, a cylinder 9 with an oval cross area concentrically arranged to the rotor 3 and an atmospheric layer 11 present in a gap 10. When the rotor 3 initiates rotation, the gas between the peripheral surface 6 and the inner surface of the cylinder 9 is exhausted from an exhaust port 11 provided to the lid body 4 by the molecular pump 8 and the pressure of the atmospheric layer 11 is reduced. Because the thickness of the atmospheric layer 11 between the cylinder 9 with an oval cross area and the peripheral surface 6 of the rotor 3 with a circular cross area becomes non-uniform along the peripheral direction of the rotor main body 3 and thick places and thin places are symmetrically present at two places, unstable vibration can be suppressed even if the rotor 3 exceeds minute vibration.
