Title: Production of light-transmitting fiber
Inventor: NISHIJIMA YOSHINDO
IPC: G02B6/00
Filed: 1978-03-28
Abstract: PURPOSE:Quartz tubes for supplying glass materials are irradiated with carbon dioxide laser and the glass material is continuously fed to the double-bottomed quartz crucible by dropping to keep the levels of liquids in the crucible constant, thereby maintaining the constant ratio of the core diameter to the clad diameter. CONSTITUTION:The top parts D and E of quartz tubes 2, 6 for supplying glass materials that are filled with molten glass with high viscosity are irradiated with laser beams that are emitted from carbon dioxide laser 9 and passed through gap F between furnaces 3, 3'. The quartz tubes are heated and the glass materials are kept in low viscosity and drop down in crucible 4 for the core part and crucible 7 for the clad part respectively. They are controlled by furnace 3' provided under the crucible to the spinning temperature and continuously spun from the bottom A. The amounts of dropped liquid is controlled to keep the levels B and C in the double-bottomed crucible constant respectively, thus keeping the dratio of the core diameter to the clad diameter of fiberglass constant.

Title: Secondary battery
Inventor: SHIRAI HIROYOSHI
IPC: H01M10/36
Filed: 1983-03-05
Abstract: PURPOSE:To improve the charge-and-discharge characteristics of a secondary battery, in which an oxygen electrode is used, by using a first electrode having a coating consisting of a high molecular compound in which molecules of a planar annular metal complex are bound together, a second electrode and electrolyte to constitute the battery. CONSTITUTION:A secondary battery is constituted of a first electrode having a coating consisting of a high molecular compound in which molecules of a planar annular metal complex are bound together, a second electrode and electrolyte. As the planar annular ligand of the above planar annular metal complex, phthalocyanine is optimally used in terms of charge-and-discharge characteristics. As a central metallic atom to which the planar annular ligand is attached, Co is specially preferred. In a high molecular compound containing such a planar annular metal complex residue, its side chain may consists of the complex residue. Here, it is preferred that a high molecular main chain to which the complex residue is bound be hydrophobic. As a result, the high molecular compound also carries oxygen during charging thereby markedly improving charge-and-discharge characteristics. In addition, the strength of the coating is increased and the life is improved.

Title: Controlled release coated fertilizer
Inventor: MURAYAMA SHUNICHI
IPC: C05G3/00
Filed: 1988-02-19
Abstract: PURPOSE: To improve a gradually releasing property and a resistance to caking of a fertilizer and to prevent an environmental pollution at the time of production by coating a chemical fertilizer with a resin film having a specified glass transition temp.  
     CONSTITUTION: One or ≥2 kinds monomers consisting of an arom. vinyl compd. such as styrene, an unsatd. carboxylic acid such as acrylic acid and fumaric acid and its neutralized salt and ester, etc., are polymerized. An obtained eq. emulsion of a homo- or copolymer or a mixture of ≥2 kinds aq. emulsions is sprayed on the solid chemical fertilizer to form the resin film having the glass transition temp. of ≥60°C on a surface of the fertilizer. The gradually releasing property and the resistance to caking are improved since the fertilizer exhibits effect by interposing the resin film. The pollution to the environment is prevented since solvent is not almost used at the time of production.

The polyester resin part is the polyester resin obtd. by the co-condensation polymn. of the diol component expressed by the formula, divalent carboxylic acid, etc., and trivalent and higher polyvalent carboxylic acid, etc. The value of the hydroxyl value/acid value of the vinyl resin-contg. polyester resin is specified to >=1.2 to lower the lowest fixing temp. and to improve fluidity. The grindability of the binder resin is not improved if the number average mol.wt. exceeds 11,000. The grindability is not improved if the content is <5wt% of the polyester resin even if the number average mol.wt. is <=11,000. The deterioration in image quality arises after the prepn. of the toner if the content exceeds 42wt%.

Abstract: PURPOSE:To surely write data in a picture element group and to prevent the generation of misdisplay or deterioration in image quality by providing the title circuit with 1st and 2nd sample/hold (S/H) circuits so that a display data writing time goes to a sufficiently long horizontal display period. CONSTITUTION:The 1st S/H circuit 16 holds display data sampled at a horizontal display period t1 and outputs the data to the 2nd S/H circuit 20 at a blanking period t2 following the period t1. The 2nd S/H circuit 20 holds the inputted display data and outputs the held data simultaneously to a column line group of a matrix type display panel 10 at the horizontal display period t1 following the period t2. Since a scanning signal is outputted to the row line group of the panel 10, the display data are written and displayed on the picture element group of the panel 10.
