摘要： PURPOSE:To obtain excellent characteristics in a low temperature region, by using a polarization beam splitter, which has only multilayered films on one surface in this structure, for each of a polarizer and an analyzer. CONSTITUTION:A polarizer 1 and an analyzer 3 are formed with polarization beam splitters. Each splitter has multilayered films, e.g., MgF2, ZnS and MgF2, on one surface of a substrate. A Faraday effect element 2 is arranged between the polarizer 1 and the analyzer 3. Since the multilayered films are provided in the polarization beam splitter, this sensor has a function for dividing electric vector into a component, which is in parallel with an incident plane to the polarization beam splitter and a component, which is vertical to the incident plane to the polarization beam splitter, when light in a random polarization state is inputted. In this way, excellent characteristics of the polarizer and the analyzer are obtained even in a low temperature region.

CONSTITUTION:A polarizer 1 and an analyzer are formed with polarization beam splitters, which have multilayered films, e.g., MgF2, ZnS and MgF2, on one surface of each substrate. A 1/4 wavelength plate 2 and a Pockels effect element 3 are arranged between the polarizer 1 and the analyzer 4. Since the multilayered films are used in the polarization beam splitters, this sensor performs a function for dividing electric vector into a component, which is in parallel with an incident plane to the polarization beam splitter and a component, which is vertical to the incident plane to the polarization beam splitter, when light in randomly polarized state is inputted. In this constitution, excellent characteristics of both the polarizer and the analyzer are obtained in a low temperature region.

摘要： PURPOSE:To make assembling easy and to attain the measurement of a high magnetic field by arranging a polarizer and an analyzer correspondingly to multilayer films and arranging a Faraday effect element to be also used as a rotary polarizer between the polarizer and the analyzer. CONSTITUTION:The polarizer 1 and the analyzer 3 are polarized beam splitters having respective multilayer films and formed on one side of a substrate. The Faraday effect element 2 acts also as a lambda/4 rotary polarizer having 45 deg. natural rotary polarizing performance. When the multilayer film faces of the polarizer 1 and the analyzer 3 are directed to the element 2, only the element 2 between the multilayer films of the polarizer 1 and the analyzer 3 has Faraday effect and a high magnetic field can be measured. In addition, assembling is simple.

摘要： PROBLEM TO BE SOLVED: To provide a power supply system which operates singly without depending upon commercial power and besides constructs a highly reliable private power generation facility. SOLUTION: This system has a power generation facility 2 connected in parallel with a power supply path 10 to power load and a secondary battery facility 3 as components. In case that the quantity of power generated by a power generation facility falls short of the quantity of power consumed in load, the power accumulated in the secondary battery 4 constituting a secondary battery facility is supplied. In case that the quantity of power generated by the power generation facility is superfluous, the secondary battery is charged with it. The excess and shortage between the quantity of power consumed in the power load and the quantity of power generated by the power generation facility is detected by detecting the phase difference between the voltage phase and the current phase of the power supplied to power load.

摘要： PROBLEM TO BE SOLVED: To provide a distributed power supply control system which prevents the generated power of a distributed power supply from being supplied directly, to both a power system and the load. SOLUTION: The load 5 is connected to a power system 1, and a distributed power supply 4 is connected to the power system 1 via a 1st switch 6 and 2nd switch 7. An battery 2 is connected to a branch point between the 1st switch 6 and the 2nd switch 7 via an AC-DC converter 3. The 1st switch 6 and the 2nd switch 7 are not closed at the same time. When the distributed power supply 4 is in operation, the state in one in which the 1st switch 6 is opened and the 2nd switch 7 is closed and the distributed power supply 4 is connected to the accumulator 2 but not to the power system 1. When the battery 2 is discharged, the 1st switch 6 is closed and the 2nd switch 7 is opened, and the battery 2 is connected to the power system 5, so that the power is supplied to the load 5.

摘要： PURPOSE: To protect a heat storage material from being deteriorated or a heat storage material-sealed vessel from being damaged in a heater which generates hot air by electric heating, using a latent heat storage material. CONSTITUTION: A plurality of heat storage material-sealed vessels 7 are laid out with a proper vent clearance in a casing 1, thereby forming the heat storage material-sealed vessels 7 with an electric heating plate by the application of electric power. A latent heat storage material 10, which phase-transfers from a solid to a liquid by heating, is sealed into the heat storage-sealed vessels 7. An inactive gas 11 is fed in the upper space of the casing while a pressure sensor 12 is installed to either one of the vessels 7.

摘要： PURPOSE:To provide a superconducting magnetic field generator which can arrange peripheral devices close to a superconducting magnet by enhancing a magnetic shield without inviting complication, large size, increase in weight, or the like of the device. CONSTITUTION:An inner tub 1 receiving a superconducting magnet 3 is enclosed with a composite shield plate 5. The composite shield plate 5 is composed of materials integrating a high temperature superconductor with a metal plate having high heat conductivity, and the high temperature superconductor is cooled at a temperature showing a superconducting phenomenon by cooling means (a liquid nitrogen vessel 6 in the figure). Thus, a thermal shield is carried out using a prior art thermal shield structure, while the excellent magnetic shield can be carried out due to the Meissner effect of the high temperature superconductor.

摘要： PURPOSE:To obtain a superconductive wiggler for generating a higher magnetic field. CONSTITUTION:Each coil core 5a, 5b, 6a, 6b, 7a, 7b constitutes a bitter type coil and serves as a coil by itself as well as a magnetic path for passing a magnetic line of force generated from each coil 1a, 1b, 2a, 2b, 3a, 3b. Thus, a very high magnetic field is generated between each coil and each coil core at the upper side and between each coil and each coil core at the lower side by flowing respective electric currents to these coil and by flowing respective electric currents to these coil cores. Accelerated electrons are introduced in the very high magnetic fields. The magnetic field deflects the electron orbit to radiate an electromagnetic wave.

摘要： PURPOSE:To make it possible to detect a vibration state without being affected by the electrical noise, by observing the photoelastic state generated in a photoelastic effect element with beam. CONSTITUTION:The polarized beam emitted from semiconductive laser 5 is guided to a beam splitter 7 by a fiber 6 to be split into two beams. Subsequently, one polarized beam is passed through a photoelastic effect element 10 through a fiber 8 and a lens 9, and condensed by a lens 11 to be guided to an optical coupler 17 by a fiber 12. Further, the other polarized beam is guided by a fiber 13 to be guided to the coupler 17 by lenses 14, 15 and a fiber 16 and coupled with the beam guided by the fiber 12 and passed through the element 10 to be detected by a beam detector 19. When vibration is sensed by a strain sensor 1, the element 10 moves up and down and, therefore, the element 10 is compressed or restored to the original state. As a result, the refractive index of the element 10 is changed and interference is generated by the coupling with polarized beam not passing through the element 10 and the amplitude and phase interval of vibration can be detected by the detector 19. Therefore, a vibration state can be detected without being affected by the electrical noise.
