Title: Polarization plane controller for delayed self-heterodyne detection
Inventor: RAN MUNEKI
IPC: G02F1/01
Filed: 1987-03-31
Abstract: PURPOSE:To obtain a small-sized and inexpensive polarization plane controller for heterodyne detection by using a 1st polarizing means having a Fabry-Perot resonator and quarter lambda plate in the rear stage in place of a Faraday element and using electrooptic elements for both the 1st and 2nd polarizing means. CONSTITUTION:Light 1 to be measured is bisected by an optical branching filter 21. One of the light is subjected to a frequency shift by an acoustooptic modulator 3 and is entered to the 1st polarizing means 60a. This light is circularly polarized by the electrooptic elements 24a, b of the means 60a and is linearly polarized by the quarter lambda plate 27 through the Fabry-Perot resonator 23. This polarized light enters a polarized beam splitter 28. The voltage on the elements 24a, 24b of the splitter 28 is so controlled as to allow transmission of the more P wave. The other light is entered through a delay fiber 22 to the 2nd polarizing means 60b and the polarization plane is controlled to the linearly polarized light in the same manner as in the means 60a. The P wave transmits the splitter 28, is circularly polarized by the quarter lambdaplate 27, is reflected by the resonator 23 and is again linearly polarized by the plate 27. The S wave is reflected by the splitter 28 and is joined to the primary light from the modulator 3 to constitute the interference light which enters a photoelectric converter 31a.

CONSTITUTION:When an electromagnet for attraction use is constituted of a core and an electromagnetic coil. As shown in the drawing a large electric current is applied at an initial stage when an attraction force is obtained (P2, P3). After an object to be attracted has been attracted, an excitation current which is a necessary and sufficient electric current for attracting and holding it is applied to the electromagnetic coil. When the attraction force is disappeared (P4 to P6), the excitation current is cut off and, after that, DC and/or AC degaussing current is applied. In order to confirm the attraction and the detachment and to detect the disconnection of the electromagnetic coil, a high-frequency current is applied to the electromagnetic coil and a change in an inductance is detected as a change in the high-frequency current.

Title: Method for judging setting state of coating film of lining on pipe interior surface
Inventor: ISHIZAWA TOMOHIRO
IPC: B05D7/22
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To enable a double or a lap coating process to be carried out in an appropriate state by judging a dry setting state based on whether a coating film for lining in a preceding step is fluidized by a specified blast air volume, when forming the coating film by a multilayer lining process after polishing and sweeping the interior surface of an existing water feed pipe. SOLUTION: When performing a lining work on existing piping 1 such as a water feed pipe in order to regenerate the piping 1, a contaminant such as scales in the interior of the existing piping 1 is previously removed appropriately with a polishing/ sweeping means, and then the interior is dried to perform the lining process in a clean state. In this lining work, the piping 1 is internally liquid while a gas for blow- stretching a coating is heated and supplied, with the help of a heating means 11. Further, when determining whether dry or cured state of the lining coating film, a blast air flow from the heating means 11 is set at a correction blast air flow value to send the air, and then the air flow variation is detected by a pressure detection means 22. When the variation is slight, it is interpreted that the coating film is already dry-set.  On the other hand, when the variation is significant, it is judged that the coating film is not yet dry-set.
