Abstract: A battery including a separator having a satisfactory ammonia trapping property is speculated to exhibit a less self-discharge and a higher capacity-holding rate. The ammonia trapping property is speculated to be increased with an increasing degree of sulfonation of a constitutive polyolefin fiber. However, a highly sulfonated conventional polyolefin has a deteriorated fiber strength and highly sulfonated portions thereof are peeled or eliminated, and the resulting fiber cannot have a significantly high degree of sulfonation. The invention is therefore intended to provide a separator having an improved ammonia trapping property. The invented separator includes a polyolefin resin fiber having large amounts of introduced sulfonic groups. Specifically, the separator is one containing a fiber obtained by sulfonating a polyolefin resin fiber having an intrinsic viscosity number of 0.2 to 1.0 dl/g, one including a fiber obtained by sulfonating a polyolefin resin fiber and having a BET specific surface area of 0.

There is also disclosed a machine operating-state monitoring system and method employing the rotational phase difference detecting system. The detecting system has a first rotating body (13) with a first mark (12), a second rotating body (11) with a second mark (10), a mark sensor (4) for detecting the first mark, a first camera (2) for imaging the second mark when the mark sensor detects the first mark, and a display section (7) for displaying the second mark imaged by the first camera. The rotational phase difference is detected from a position of an image of the second mark displayed on the display section and is thus detected very accurately with a simple construction comprising the mark sensor, the first camera, and the display section.

Abstract: A picture pickup block (12) of an optical head body (1) is detachably attached to a camera body (2). The picture pickup block (12) includes an EEPROM (129), which stores data in association with a picture pickup element, such as shading correction data, and setup data for the video camera, including signal-use location data. When the power is turned on, a microcomputer (201) in the camera body (2) reads setup data from the ROM (129), and sets up the video camera by controlling each circuit of the picture pickup block (12) and the camera body (2). For example, based on shading correction data, setup is performed so that a video signal for which shading correction has been performed is output. Also, based on signal-use location data, setup is performed so that a video signal in accordance with the appropriate signal standards of a particular signal-use location is output by controlling a level conversion circuit (206) and a setup level signal adding circuit (207).
