Title: Optical recording material and optical recording method
Inventor: TANAKA MASAOMI
IPC: G11B7/243
Filed: 1987-08-14
Abstract: PURPOSE:To obtain an optical recording material having excellent environmental stability, by providing a particle layer comprising single dispersed particles arranged in order on a surface of a substrate, and reading the presence or absence of diffracted light from the particle layer or the differences in the magnitude of the diffracted light as signal information. CONSTITUTION:This optical recording material strongly reflects only rays of a specified wavelength as a recording signal, and the wavelength of the rays reflected as the recording signal can be arbitrarily varied by varying the size of single dispersed particles used as the recording medium. For example, when spherical single dispersed particles having a diameter of 0.15-0.4mum constitute a regulated structure, the surface of the particle layer emits monochroic rays with clear metallic luster due to the diffraction of visible rays. As a substrate 1, any of conventionally known substrates may be used. The thickness of the regulated structure layer 2 is preferably 0.5-10.0mum, from the viewpoints of higher intensity of diffracted rays and higher accuracy in writing. A hardened layer 3 is provided for fixing the regulated structure layer 2, and it is necessary to pay attention to the refractive index of a resin being used therefor.

Title: Hot-water supplier
Inventor: AOKI YUTAKA
IPC: F23N5/26
Filed: 1996-07-11
Abstract: PROBLEM TO BE SOLVED: To prevent overheating or freezing of a hot water supplier with an inexpensive constitution by a method wherein the overheating of a combustion chamber is detected based on the value of resistance, which is detected by energizing a conductive body, while the amount of supplying electric power to the conductive body is increased when there is the possibility of freezing during stopping combustion. SOLUTION: An overheating and freezing preventing device 40 is obtained by a method wherein one series of a meandering linear conductive pattern is printed uniformly on the whole area of an insulating sheet made of a resin by carbon ink or the mixture of conductive carbon and the resin while the overheating and freezing preventing device 40 is inserted and installed between a combustion chamber 12 as well as a heat exchanger 13 and an outer cylindrical casing 11 to connect the device 40 to a controller 20 through a lead wire 43.  During the combustion of a burner 14, the abnormal overheating of the combustion chamber 12 is detected based on the change of an electric resistance, detected by energizing the carbon ink, to stop the combustion of the burner 14 while the device 40 is utilized as a freezing preventing heater when there is the possibility of freezing during stopping the combustion of the burner 14. In this case, the amount of conducting current is increased to generate heat and accordingly, the freezing of a water supplying passage and a hot-water supplying passage is prevented by heating.

Title: Concentrated separation of fatty acid ester
Inventor: TOKUMORI TSUNEO
IPC: B01D11/00
Filed: 1995-08-09
Abstract: PROBLEM TO BE SOLVED: To effectively and economically conduct concentrated separation of a specific fatty acid ester such as docosahexaenoic ester by extractive separation of a fatty acid ester mixture by a specific means using a fluid in supercritical state. SOLUTION: First, a fatty acid ester mixture is subjected to extractive separation with a fluid in supercritical or subcritical state to remove low-molecular- weight fatty acid esters. Subsequently, the resultant extraction residues is introduced into an extraction column having rectification function to conduct both extraction and rectification with a fluid in supercritical or subcritical state, thus accomplishing the objective concentrated separation of a specific fatty acid ester in the extraction phase or extraction residues. For the concentrated separation of an eicosapentaenoic or docosahexaenoic ester as an example of the fatty acid ester, it is preferable that extraction temperature and extraction pressure be at 46-100 deg.C and 80-300atm, respectively. The fluid in supercritical state to be used is e.g. carbon dioxide < 75kg/cm<2> G in pressure and <31 deg.C in temperature.  The extraction column having rectification function can be obtained, for example, by installing a reflux means etc.
