    Abstract: In the sample-and-hold circuit for laser power detection signal and servo signal, the sample-and-hold operation timing is controlled to set by monitoring the output from the sample-and-hold circuit. In the invention of this application, the sample-and-hold timing is changed to be larger or smaller than the estimated timing, and reference is made to the result of the monitoring, thus determining the optimum timing. The sample-and-hold timing is controlled to fix to this optimum value.

    Abstract: The invention is to a non-woven fabric sheet for a storage battery separator. The sheet has an excellent property of holding electrolyte by using conjugate fibers having a specific sectional form. The sheet comprises an ethylene copolymer having a specific structure which can introduce a desirable amount of sulfo groups efficiently under mild reaction condtions. Conjugate fibers having a split sectional form include a first component and a second component having a radial arrangement. The conjugate fibers are obtained by forming an ethylene based random copolymer containing a unit represented by a formula --CH.sub.2 CH(COOH)--, with polypropylene. Subsequently, a non-woven fabric sheet of a thermally bonding type is obtained by mixing the conjugate fibers with polypropoylene fibers. Subsequently, a non-woven fabric sheet for a storage battery separator is obtained by sulfonating the non-woven fabric sheet using gas such as SO.sub.3 to form a unit of the formula --CH.sub.2 C(SO.sub.3 H)(COOH)--.
