Abstract: PROBLEM TO BE SOLVED: To provide a separator for battery which has a good shutdown property and a good heat resistance, by laminating a minute porous layer consisting of a cellulose fiber, and a synthetic fiber generating no thermal melting; and a minute porous layer with thermal melting property. SOLUTION: A minute porous layer 44 (an adiabatic layer) generating no thermal melting is formed from a pulp slurry which consists of a cellose fiber, and a synthetic fibril refined to the water retentivity less than 210 to 450%. And a thermal melting type of minute porous layer 45 (thermal melting layer) which consists of a polyolefin resin is formed from a pulp slurry made by mixing a polypropylene synthetic pulp or the like, and a polypropylene/polyethylene core sheath fiber or the like. By laminating both slurrys to manufacture a paper by using an inclined wire to the adiabatic layer 44, and a circular net to the thermal melting layer 45, to form a laminate sheet. The laminate sheet laminating the adiabatic layer 44 and the thermal melting layer 45 is calendered at about 80 deg.C and the line pressure about 50kg/cm, to obtain a separator for battery 34. This separator is used to a secondary battery and the like.

Abstract: PROBLEM TO BE SOLVED: To provide an ink-jet printer capable of suppressing generation of satellite drops and, an apparatus and a method for driving an ink-jet printer recording head. SOLUTION: Two piezoelectric elements 116a, 116b are set for each ink chamber 114 corresponding to a nozzle 118. After one piezoelectric element 116a starts to discharge ink drops, the other piezoelectric element 116b is displaced while the ink chamber 114 is shrunken because of a displacement of the piezoelectric element 116a, so that the ink chamber 114 is shrunken further. Trailing of ink drops is accordingly stopped at an early stage and generation of satellite drops is restricted. Generation of the satellite drops can be restricted most effectively particularly if the piezoelectric element 116b is started to be displaced at a time point when the piezoelectric element 116a has been displaced most.
