Filed: 1991-04-26
Abstract: PURPOSE:To record a luminance signal and a color signal in a video signal separately without increasing tape consumption quantity by using a magnetic recording tape for double side recording so as to double simultaneous recording area of the tape. CONSTITUTION:At first, a magnetic substance is coated to both sides of a tape, and magnetic heads 5, 6 are provided to both sides of a middle cylinder 7 placed between upper and lower cylinders 8. Then a folded tape is wound to a rotary cylinder head 1 so as not to be in duplicate and in a way of oblique recording. Then the magnetic head 5 is used to record a luminance signal on the surface of the tape supplied from the upper stage tape supply reel 3 and the magnetic head 6 is used to record a color signal to a rear side of the tape folded by a tape winding guide 2 and the tape is returned to a lower stage tape winding reel. Thus, the luminance signal is recorded on the front side and the color signal is recorded on the rear side simultaneously. Furthermore, the magnetic heads 5, 6 adopt 2-head oblique recording.

Title: Hot press
Inventor: NEMOTO MASAMI
IPC: B30B15/34
Filed: 1985-09-02
Abstract: PURPOSE:To eliminate the uneven surface on the surfaces of both upper and lower hot platens occurred from leaked cooling water by providing a feed valve for cooling water and a drain circuit for removing the cooling water leaking from a drain valve and entering the inside of a cooling passage to the outlet side for the cooling water of both hot platens. CONSTITUTION:The feed valve 13 and drain valve 8 are opened in the stage of cooling both the upper and lower hot platens 7, 5. The cooling water passes a strainer 14 and the feed valve 13, flows through the cooling water passage on the upper and lower hot platens 7, 5 and is discharged through a strainer 17 and the drain valve 18. The feed valve 13 and the drain valve 18 are closed to shut off the flow of the cooling water to the cooling water passage in the stage of heating the hot platens 7, 5. However, the cooling water cannot be thoroughly shut off even if the feed valve 13 and the feed valve 18 are held closed in the stage of heating. The cooling water, therefore, leaks from these valves and intrudes into the cooling water passages of the upper and lower hot platens 7, 5. The valves 20 and 21 of the drain circuit 19 are thereupon opened, then the leaking cooling water is discharged through he drain circuit 19. As a result, the remaining of the cooling water in the hot platens 7, 5 is obviated and the temp. distribution on the surfaces of the hot platens 7, 5 is made uniform.

Title: Optical fiber zero phase current transformer
Inventor: TOMAKI YOSHIAKI
IPC: G01R31/08
Filed: 1986-08-20
Abstract: PURPOSE:To obtain a small-sized light wt. safe zero phase current transformer, by winding an optical fiber around a three-phase distribution line so as to surround the same and connecting a signal converter between both ends thereof. CONSTITUTION:An optical fiber zero phase current transformer 2A is constituted of the single mode optical fiber 4 wound around a three-phase distribution line 1 and the signal converter 5 connected between both ends of the optical fiber 4. The converter 5 has a light emitting element 6, a polarizer 7, a light receiving element 9 and an electronic circuit 10 mounted therein. The light emitted from the element 6 is linearly polarized by the polarizer 7 permitting the passage only of light of a wave component in one direction to be incident to the optical fiber 4. When a magnetic field is applied to the optical fiber 4, the plane of polarization thereof rotates in proportion to the magnetic field applied by Faraday effect. Now, when an earth accident is generated, as the result of the flowing of a zero phase current to the distribution line 1, the circumference integration of the magnetic field surrounding said line 1 becomes the value proportional thereto and the plane of polarization of the linearly polarized light passing through the optical fiber 4 also receives the rotation proportional to the zero phase current and the electric signal photoelectrically converted by the element 9 through the detector 8 also changes to make it possible to detect the zero phase current.
