摘要： PROBLEM TO BE SOLVED: To manufacture a battery capable of reducing the degree of swelling of the binder in an electrode body structure to an electrolyte, causing neseparation of an electrode mix layer, safe and excellent in cycle characteristic by preparing the binder solution for forming a nonaquous battery electrode by dissolving a vinylidene-based polymer for specifying a heterogenous binding quantity in an organic solvent. SOLUTION: A binder solution for forming an electrode having a heterogenous binding quantity less than 4% is prepared by dissolving a vinylidene fluoride-based polymer in an organic solvent. The organic solvent preferably has polarity, and a nitrogen contained organic solvent such as N-methyl-2- pyrrolidone and dimethylformamide having large dissolving power is more preferable. In preparing the electrode forming binder solution, the vinylidene fluoride-based polymer is dissolved in the organic solvent at a ratio 0.1 to 15 pts.wt. per 100 pts.wt. of the solvent, particularly preferably 1 to 10 pts.wt. When the ratio is less than 0.1 pts.wt. a ratio occupied by the polymer in the solution is too small to obtain binder effect.

摘要： PURPOSE:To insulate a high molecular piezoelectric film from external acoustic sound and light rays by setting the main direction of propagating vibration wave produced at an input electrode perpendicularly to an electrode confronting direction and reducing the reflecting noise applied to an output electrode. CONSTITUTION:Since the elongating and contracting motion of a film due to reverse piezoelectricity produced at input side electrodes 1, 1' occur in the main orientation axial direction (an MD direction of arrow) of the film when electrode pairs 1, 1' and 2, 2' are confronted in the vicinity at an equal interval, the vibration wave is propagated in the MD direction, and is reflected at both ends of the film in the MD direction. If the MD direction of the film is a direction perpendicular to the electrode confronting direction as designated by an arrow (b), the main direction of the vibration wave propagating from the electrodes 1, 1' is a direction as designated by (b), and almost no reflecting wave noise is applied to the electrodes 2, 2'. Thus, the film can be insulated from external acoustic sound and light rays.

摘要： PURPOSE:To enable the picking-up of an image around an infrared ray reception element, nearly without a dead angle, by moving a rotary shutter having a light transmission slit, along the outside surface of the element. CONSTITUTION:When a shutter 6 is rotated and a slit 8 is moved around an infrared ray reception element 1, a thin partial image made of light transmitted through the slit 8, in an ambient image composed of light condensed by a lens 12, is displaced across the parallel linear electrodes 3 of the light reception element 1. The change in each of electric signals picked out from the parallel linear electrodes 1 is observed to determine the whole distribution of the infrared ambient image.

摘要： PURPOSE:To obtain the pyroelectric image with high precision by providing plural electrodes, which can be regarded as being electrically parallel to each other, to one side at least of a pyroelectric element and by moving a shutter that is provided with a light transmittable slit on crossing the respective electrodes. CONSTITUTION:The pyroelectric element 1 is made up such that parallel black metal electrodes 3 are evaporated onto one side of the pyroelectric film 2 obtained by forming vinyliden polyfluoride and an aluminum electrode 4 is evaporated onto the back of the film. For the shutter 5, a light shielding film 6 such as black colored paper or the like, which has the light transmittable slit 7 the upper and lower widths of which are uniform, is used and its both ends are wound around the right and left rollers 8, 8'. A reversible motor 9 operates so that the shutter film can be moved at a fixed speed and be inverted every time the slit 8 reaches one end of the pyroelectric element. When a thermal photographic object 10 is present in front of the shutter 5, a thermal image can be photographed by one way movement of the slit 7.

摘要： PURPOSE:To enable the element formation with very thin arbitrary area, by providing a plurality of parallel electrodes so that a pair of pyroelectric macropolymer layer can bridge the conductive layer at the center and the matrix shape can be formed at the external surface. CONSTITUTION:The conductive layer 6 is provided over the entire surface of the surfaces opposing between a pair of pyroelectric macropolymer layers 7 and 8 with evaporation. The layer 6 is thinly formed in film shape so that the layers 7 and 8 can be heated at infrared ray radiation. Next, the row detection electrode groups x1-x4 are placed on one surface of the layer 7 with bonding and the column detection electrode groups y1-y4 are placed in contact with one surface with bonding so that matrix shape cross point with it can be formed. Those electrode groups are formed thinly in film shape so that radiated infrared rays can heat the layers 7 and 8 effectively, and the electrode groups at the infrared ray reception surface side are taken as transparent electrodes. The layer 6 is used with grounding so that electrostatic coupling can not be made among the electrode groups x1-x4 and y1-y4. With this constitution, the layers 7 and 8 are heated with infrared rays to produce pyroelectricity and charge to the electrode groups. In this case, electric signal is obtained by using the relation between the layer 6 and the cross point of the electrode groups.

摘要： PROBLEM TO BE SOLVED: To obtain the subject binder capable of manifesting a good adhesive strength, etc., to a powdery electrode material and a collector with a small amount thereof used by using a sulfonated polyvinylidene fluoride-based resin as a binder. SOLUTION: This nonaqueous binder for a battery or a cell is obtained by sulfonating a polyvinylidene fluoride-based resin comprising a homopolymer of vinylidene fluoride or a copolymer of the vinylidene fluoride and a fluorine- containing monomer copolymerizable with the vinylidene fluoride such as vinyl fluoride, trifluoroethylene or chlorotrifluoroethylene. The polyvinylidene fluoride- based resin preferably has 0.5-10.0 intrinsic viscosity. The sulfone groups to be introduced may further be converted into a salt of lithium ion. A solution containing the binder dissolved in an organic solvent can be mixed with a powdery electrode material to provide an electrode mixture.
