IPC: G02B6/00
Filed: 1978-02-23
Abstract: PURPOSE:A glass tube that is coated with the interlayer of glass film on the inner surface is shrinked in the inner diameter to the outer diameter of the core rod, thereby producing optical fibers with high roundness and no inclination in film thickness by the rod-in-tube method. CONSTITUTION:After glass tube 1 is coated with glass film 2 as the interlayer on the inner surface, the inner diameter is shrinked by use of burner 4. Then core rod 3 with the outer diameter close to the inner one of glass tube 1 is inserted and the both are integrated by fusing with heat. They are sufficiently treated with heat to adhere core rod 3 closely to glass tube 1 and remove strains at the interface. When the heating process is carried out by standing the glass tube upright, the inclination in wall thickness and reduction in roundness can be effectively reduced. Then, the resulting rod is drawn into small cross section to produce said optical fibers.

Abstract: PURPOSE:To facilitate the tracking adjustment by judging data ineffective and displaying the result if the data representing the difference of deviation exceeds a proportional region in detecting and displaying the difference of deviation toward inner and outer circumferences from a reference track in the off-track quantity measuring instrument of the magnetic head. CONSTITUTION:The magnetic head 1 to be adjusted receives a start signal from an alignment disk of the di-bit system, a comparator 5 and a timing generator 6 receive it to generate a timing signal thereby activating an analog switch 7. Then the succeedingly inputted data are held by sample-and-hold circuits 10, 13 depending on the inner/outer circumference of the reference track, the difference is obtained by subtractor 14 and the result is displayed by an indicator 21. In this case, when the difference is proportional to the actual off-track, it is displayed to be effective depending on the output of an AND circuit 17 via comparators 15, 16. If the result is deviated toward the outer/inner circumference largely, it is displayed to be ineffective by the output of AND circuits 19, 20 respectively.

Title: Manufacture of heat-shrinkable tube
Inventor: NAKAJIMA KOICHI
IPC: B29C55/22
Filed: 1988-02-01
Abstract: PURPOSE:To reduce friction resistance between a heat-shrinkable tube and a molding tube to a large extent by making a supersonic transmitting section in contact with the molding tube and giving supersonic vibrations when a heat- shrinkable tube fore expanded is heat softened with a heater and the tube is expanded until being in contact with the inner wall of the molding tube by means of inner pressure of the tube and molded. CONSTITUTION:A heat-shrinkable tube 3a before expansion is heat softened at the time of passing through a heater 1, during which the inner section of a molding tube 2 is expanded because of the inner pressure applied to the inner section of the tube, and the expansion is discontinued at a point where the outer surface of the tube 3 and the inner surface of the molding tube 2 are in contact. At that time, friction resistance is generated between the outer surface of the tube and the inner surface of the molding tube, and as the molding tube 2 receives supersonic waves from the supersonic transmitting section 4 and vibrates, the apparent friction coefficient in the inner surface of the molding tube 2 gets smaller, which makes the resulting friction resistance actually very small. The friction resistance between the heat-shrinkable tube 3 and the molding tube 2 is reduced to a large extent.

Title: Dynamically compensating circuit of unnecessary magnetic field
Inventor: KOBAYASHI MASAKI
IPC: G09G1/16
Filed: 1982-02-10
Abstract: PURPOSE:To eliminate the influences of a magnetic field apparently on a CRT screen, by measuring the direction and intensity of the unnecessary magnetic field with a magnetic sensor, estimating the influence exerted or an electron beam, and compensating the position of the beam landing. CONSTITUTION:A magnetic sensor section 7 divides a magnetic field into each component of an orthogonal coordinates system x, y, and z, and converts the magnetic field into quantities of electricity corresponding to the intensity of each component. An operating section 8 estimates the influence of the magnetic field to an electron beam in three-dimension based on an electric signal generated by the magnetic sensor section 7, and calculates most suitable correcting amounts for each section of a CRT monitoring circuit 16, and then, transmits them to a control section 9. The control section 9 converts the signal into a correcting amount corresponding to the electric characteristic and transmits it to each circuit, and controls the correction. The CRT monitoring circuit 16 is not used for preventing the influence of the magnetic field to the electron beam, but finally for preventing the variation of the landing position on the fluorescent screen of the CRT.
