Title: Magneto-optical recording system
Inventor: WATADA ATSUYUKI
IPC: G11B11/105
Filed: 1990-03-15
Abstract: PURPOSE:To realize the two-side recoding and the direct overwrite of high reliability by setting the direction of a magnetic field to be impressed to the recording layer of double-layer structure at the time of initialization if there is an initializing process and at the time of recording if there is no initializing process so as to be a definite direction whichever side is recorded. CONSTITUTION:After passing through the initializing process to make the direction of the magnetization of one, at least, or more layers among two or more layers uniform by the magnetic field, or without the initializing process, a bias magnetic field is impressed, and simultaneously, magneto-optical recording capable of direct overwriting is executed by changing the intensity of irradiation light. In this case, the direction of the magnetic field to be impressed at the time of the initialization if there is the initializing process or the direction of the magnetic field to be impressed at the time of the recording if there is no initializing process is set so as to be always the definite direction to a magneto-optical recording medium 1 whichever side is recorded by magnets 5, 4. Thus, since the large magnetic field is not impressed in a reverse direction, a recording state is stabilized, and the two-side recording and the direct overwrite of the high reliability can be attained.

Title: Polarization interference spectroscope
Inventor: SASADA KATSUHIRO
IPC: G01J3/45
Filed: 1989-03-20
Abstract: PURPOSE:To measure spectrums at multiple measuring points at a high speed simultaneously at all measuring points over all the wavelengths by arranging a Wollaston prism, two polarizers and a two-dimensional multichannel photodetector. CONSTITUTION:An interference fringe generated at a point of a light source 1 to be measured forms an image in the x-axis at a point A' of a two-dimensional multichannel photodetector 7. Likewise, interference fringes generated at points B and C of the light source 1 form images in the x-axis at points B' and C' of the photodetector 7. In other words, light of the light source 1 is converted into an interference fringe by a polarization interference optical system to be incident into the photodetector 7 with an imaging lens 6. On the other hand, one row of photoelectric elements in the y-axis of the photodetector 7 is made to correspond to each of sections in which the light source 1 is subdivided in the y-axis so that interference fringes in the respective sections are detected with corresponding one row of respective photoelectric elements in the x-axis of the photodetector 7. Thus, spectrums at points of the light source can be obtained corresponding to bits in the y-axis of the photodetector 7 by a reverse Fourier transform of interference fringe waveforms in the x-axis of the photodetector 7.

Title: Reactor initial loading core
Inventor: YAMANAKA AKIHIRO
IPC: G21C3/326
Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To secure a thermal margin in a reactor core where an average concentration is increased by mixing a flammable toxic substance into a fuel assembly with the lowest concentration in the fuel assembly consisting of a plurality of concentration types. SOLUTION: A reactor initial loading core consists of fuel assemblies 11 and 12 with two types of concentration. With the average concentration of the fuel assembly for constituting a reactor core, a flammable toxic substance where the fuel assembly 11 is mixed with 2 wt.% is 8 wt.%, a flammable toxic substance where the fuel assembly 12 is mixed by 3.7 wt.% is 10 wt.%. In this case, when the flammable toxic substance to be mixed is set to 8 wt.% or higher and the concentration of the assembly is set to 2 wt.% or higher, the effect of the flammable toxic substance continues for a required period in the fuel assembly with low concentration.  Also, when the average concentration of the assembly reaches approximately 2 wt.% or higher, the difference in neutron spectrum with a high-concentration fuel is reduced, thus effectively suppressing a thermal margin even in a reactor core where the degree of combustion is increased by increasing the concentration of the reactor core.

Title: Thermal head
Inventor: INOUE NOBUHIRO
IPC: B41J2/345
Filed: 1988-03-18
Abstract: PURPOSE:To reduce powder consumption and to enable recording of high quality which has little tailing and density irregularity by a method wherein a size of each minute heating element of a thermal head is so constructed that a recording paper feed direction width is made narrower than a line direction width. CONSTITUTION:A heating element 201c is formed on a substrate 201a so that a length L in recording paper feed direction (sub scanning direction) is shorter than a length l in a line direction (main scanning direction). This apparatus executes recording of one line by repeating recording by the same image signal a plurality of times, feeding the recording paper at a pitch corresponding to the sub scanning direction. When the heating element 201c is made to be of an above-mentioned dimensional relation, thermal responsibility becomes good, influence of heat accumulation energy decreases, and a tailing phenomenon in transfer time from a black dot to a white dot is reduced. Further, since an area of the heating element narrows, the thermal responsibility is improved, and an amount of electricity for obtaining the same energy is preferably less. Furthermore, recording density which is homogeneous and near maximum density can be obtained.
