摘要:
To provide a non-aqueous secondary battery having a capacity as high as that of a conventional battery using a conventional resin separator and achieving excellent overcharge characteristics and excellent resistance to external short-circuit, a combined electrode plate for a spirally-wound electrode group for a non-aqueous secondary battery including a current collector, an active material layer carried on the current collector and a multi-layer porous membrane carried on the active material layer is used. The multi-layer porous membrane includes a first porous membrane and a second porous membrane. The first porous membrane contains metal oxide particles and a first binder. The second porous membrane contains resin particles and a second binder. The thickness of the multi-layer porous membrane is preferably 15 to 25 μm.

The present invention provides a light-modulation element comprising at least: liquid crystal droplets having a particle size between 0.6 .mu.m-2 .mu.m, which have light-modulating functions to scatter light rays or transmit light rays and polymer matrix having an interstructure thickness of 0.5 .mu.m or less between the liquid crystal droplets. The light-modulation element works to scatter light rays or transmit light rays by turning on a voltage or turning off a voltage. The light-modulation element is produced by a polymerization process and a mixing step to separate out liquid crystal phases in a polymer matrix.

There are provided an optical disk device and tilt correction processing method for performing recording/reproduction by rapidly acquiring an optimal tilt correction value for an optical disk having a plurality of recording/reproducing layers. In an optical disk device capable of recording or reproducing information by irradiating a laser beam to each of a plurality of recording/reproducing layers of an optical disk, the tilt value is stepwise set within a predetermined range at a predetermined radius position of the recording/reproducing layer located at the farthest distance from the laser beam irradiation side so that an optimal tilt correction value can be obtained from the quadratic function by the method of least squares of the jitter or the like obtained from the disk. By applying the optimal tilt value obtained to the other recording/reproducing layer, it is possible to start recording or reproduction in a short time.

The invention provides a multilayer container that comprises a polyglycolic acid layer and a thermoplastic polyester resin layer and is much improved in terms of gas barrier properties, heat resistance, moldability, transparency and durability, and its production process. Polyglycolic acid is used as a gas barrier resin. At the body and bottom, the thermoplastic polyester resin forms an inner and an outer layer, and an intermediate layer comprising at least one polyglycolic acid layer is embedded in the thermoplastic polyester resin layer. The opening end of the container is formed of a thermoplastic polyester resin layer alone, and the body is biaxially oriented. The multilayer container has heat resistance enough to stand up to hot-filling at 93° C. for 20 seconds.
摘要:
A mixed material of liquid crystals and resin is dropped on at least one substrate in an amount greater than the amount needed to cover a display area for the LCD panel. The substrate is adhered to another substrate, and excess material is removed to the outside of a display area. The phase-separation of the liquid crystals and resin is carried out by irradiating light while pressure is added to at least one substrate, so that a liquid crystal display panel applied to a liquid crystal display device or a light shutter can be manufactured without applying a complex vacuum device.
