摘要:
In a displacement detecting method, displacement between a strip-shaped electrode (13) and the strip-shaped separator (14) is detected. The strip-shaped separator (14) is semitransparent. In the method, first, the strip-shaped electrode (13) is photographed through the strip-shaped separator (14) at a position where the strip-shaped electrode (13) and the strip-shaped separator(14) are stacked (photographing step). Based on an image photographed in the photographing step, displacement between the strip-shaped electrode (13) and the strip-shaped separator (14) is detected (displacement detecting step). In a displacement amount measuring method of measuring the displacement amount, the displacement amount between the strip-shaped electrode (13) and the strip-shaped separator (14) is calculated based on the image photographed in the photographing step.
摘要:
A method for producing a wound electrode assembly includes steps of: overlaying electrode strips (11, 13) and separator strips (12, 14) on each other, and winding the electrode strips (11, 13) and the separator strips (12, 14) on a take-up shaft (20) while pressing a pressing member (30) against the electrode strips and the separator strips. In the winding step, the pressing force of the pressing member (30) is increased with decrease in a tension T applied to at least one of the electrode strips (11, 13) and the separator strips (12, 14).
摘要:
An electrode winding apparatus and method of detecting displacement between a strip-shaped electrode and a strip-shaped separator when stacking and winding the strip-shaped electrode and the strip-shaped separator is described. A winding shaft is configured to wind the strip-shaped electrode and the strip-shaped separator, and a guide member is configured to stack the strip-shaped electrode and the strip-shaped separator before the strip-shaped electrode and the strip-shaped separator are wound around the winding shaft. An imaging device is disposed so as to photograph a portion in which the strip-shaped electrode and the strip-shaped separator are stacked between the guide member and the winding shaft from a side on which the strip-shaped separator is stacked. The imaging device is configured to photograph the strip-shaped separator and the strip-shaped electrode through the strip-shaped separator.

A manufacturing method of liquid crystal display device is provided that can increase manufacturing yield by reducing the number of layers and manufacturing costs and by preventing backlight lamp failure.In the manufacturing method of the device, a semiconductor layer 4 and a pixel electrode 5 are formed on a gate insulating film 3. Subsequently, a drain electrode electrically interconnecting the semiconductor layer 4 and the pixel electrode 5 of the pixel region A is formed by overlaying a flat solid conductive film on the substrate, followed by removing the conductive film with the use of a photoresist pattern as a mask, while exposing the semiconductor layer 4 at the pixel region A and the adjacent area C. The semiconductor layer 4 at the pixel region A is etched by using, as an index, an etching amount of the semiconductor layer 4 at the adjacent area.

A switchgear includes a chassis which is partitioned by metal earthed plates and includes a bus bar section located at a central portion, a switch section located below the bus bar section, a cable section located at a rear surface side, and a control section located at a front surface side; an air-insulated earthed disconnecting switch provided in the switch section; and a manipulating device. The switch section is separable from the chassis, and is configured as a case having a semi-closed structure which allows air to pass therethrough but prevents particles of oil and water from passing therethrough.
