An inspection device is a device that inspects the position of an electrode plate in a multilayer body, which is obtained by bonding a separator and the electrode plate to each other by means of an adhesive, from the separator side. This inspection device is provided with: an infrared light irradiation unit that irradiates the multilayer body, from the separator side, with infrared light that has a peak wavelength within the range of from 6.5 μm to 9.6 μm; a camera that takes an image of the infrared light that transmits through the separator and is reflected by the electrode plate; and a detection unit that detects the position of the electrode plate.

Inspection device, method for producing multilayer electrode body and inspection method

An insulation inspection device includes: a conveyance unit that conveys a laminated electrode in which a first separator, a first electrode plate, a second separator, and a second electrode plate are laminated; a pressure roll that presses the laminated electrode against the conveyance unit; a first terminal electrically connected to the first electrode plate; a second terminal electrically connected to the second electrode plate, further electrically connected to the conveyance unit when the first separator is disposed on the conveyance unit side, and further electrically connected to the pressure roll when the first separator is disposed on the pressure roll side; and an insulation inspection unit that applies a voltage to the laminated electrode to inspect insulation condition of the laminated electrode.

Insulation inspecting device

A thin pouch battery, which is used as a power source of a portable electronic apparatus, a portable electronic terminal, or the like, includes protrusions, into which an electrode group is inserted, formed in both a laminate film on the upper side and a laminate film on the lower side. Then, concentrically concave and convex wave shapes (concentric crest ridges or trough furrows) are formed on the top surface of each of the protrusions such that the protrusion can extend or shrink in any direction, or the protrusion has a side surface that is gradually inclined and a wave shape is formed on the side surface of the protrusion.

Flexible battery

There is provided a pouch-type battery that includes an exterior packaging member having an accommodating space in which an electrode and an electrolyte are accommodated and which has a curved shape at least in a first direction. The exterior packaging member includes a first film member on which a cup section having the accommodating space inside is provided, a second film member disposed to face the first film member, and a sealing section around the cup section, with which the first and second film members are bonded to each other and the accommodating space is sealed. A top surface of the cup section of the first film member has a curved shape and is provided with a plurality of concave portions or convex portions, and the sealing section has a curved shape in the first direction and is configured of a flat surface on which neither concave portion nor convex portion is provided.

Pouch-type battery and method of manufacturing the same

A deterioration of reproduction light is occurred by a laser drive current on which a high-frequency current is superimposed. The present invention, for example, is an optical information reproducing apparatus which irradiates a laser beam to an optical discand reads an information, the optical information reproducing apparatus includes a semiconductor laserwhich generates the laser beam, a laser drive unitwhich supplies a drive current on which a high-frequency current are superimposed to the semiconductor laser, a spindle motorwhich drives the optical discand a control unitwhich controls the laser drive unitand the spindle motor, and the control unitdetermines a parameter of the high-frequency current based on magnitude of a current on which the high-frequency current is to be superimposed.
