Title: Storage retrieval system for picture information
Inventor: YAMASHITA MITSUO
IPC: G11B27/28
Filed: 1979-11-19
Abstract: PURPOSE: To enable the storage of a series of continuous picture information by inputting a representative index code in its storage or retrieval process, by storing a single index code with an additional series code.  
     CONSTITUTION: To record a series of documents continuously, CPU7 sets the contention flag and stores a special code, page information and index code in temporary memory part 11 repectively. After the 1st-sheet information is stored and processed, the storage as to the 2nd sheet or following sheet can be performed only through storing operation without inputting any index code. To retrieve a series of documents continuously, CPU7 sets the contention flag in the same way with the storage mode and also stores the memory part with the special code, page information and index code. After the 1st document is retrieved, the retrieval as to the 2nd sheet or following one is carried out automatically without inputting the index code because the flag is set.

Abstract: PURPOSE:To measure a state of fluidized bed by a method wherein a main body of a boiler is provided with a plurality of pressure sensors and there is provided a calculator for calculating the ratio of each of frequencies to a variation width from a variation wave forms of the pressure. CONSTITUTION:Combustion air of high pressure is supplied from an air supplying line 4 into a pressure vessel 2. The inside of the vessel 2 becomes a high pressure and the air in the vessel 2 is made to flow into a main body 1 of a boiler through an air dispersion plate 2. Then, a particle coals and bed material are fluidized under a high temperature and a high pressure so as to form a fluidized bed 5. During this operation, the pressure variation of the main body 1 of the boiler is detected by seven pressure sensors 15. Variation waveforms of pressure got by these sensor 15 have the higher frequencies (N) and the smaller variation width (B) in the lower portion of the fluidized bed 5. Due to this fact, each of the frequencies and variation width are calculated by a calculator 16 from the variation waveforms of the pressure got by each of the pressure sensors 15 and then the ratio (B/N) is calculated, thereby the B/N in a height direction of the fluidized bed 5 is calculated and the value B/N indicates a uniformity of the fluidization of the fluidized bed 5 and the state of the fluidized bed 5 can be measured.

Title: Temperature-sensitive gel and its production
Inventor: HIROTSU SHUNSUKE
IPC: C08F20/56
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To obtain a temperature-sensitive gel which rapidly causes volume phase transfer by entangling hydrophilic polymer chains showing no sensitivity to temp. in the mesh of a temperature-sensitive hydrophilic polymer get in such a manner that the polymer chains can not desorb and/or by chemically linking the polymer chains to the mesh. SOLUTION: As for the monomers to form a temperature-sensitive hydrophilic polymer gel, N-isopropyl acrylamides, cyclopropyl acrylamides and N-n-propyl acrylamides are preferably used. Polymer chains showing no sensitivity to temp. are entangled in the polymer gel of the monomers above described so that the polymer chains can not desorb, and/or the polymer chains are chemically linked to the mesh of the get to obtain a temperature-sensitive get. In this method, the polymer having no temp. sensitivity is preferably a homologous series of the temperature-sensitive polymer in order to form a dense entangled state of the mesh and the polymer chains. For example, when a N- isopropylacrylamide is used as the temperature-sensitive hydrophilic polymer, homologous acrylamide polymer chains are preferably used for entangling.
