Title: Bulky nonwoven fabric and its production
Inventor: NAKANO YUSUKE
IPC: D04H1/4391
Filed: 1995-05-10
Abstract: PURPOSE: To produce a bulky nonwoven fabric excellent in strength and drape even at a low weight by laminating short-fiber webs containing a sterically crimping synthetic fiber on one side or both sides of a long-fiber nonwoven fabric and subsequently integrating under entanglement by a high-pressure water-flow treatment. CONSTITUTION: At first, a short-fiber web containing a crimping synthetic fiber in an amount of >=50% is formed. The crimping synthetic fiber is composed of a conjugate fiber having an eccentric sheath-core structure in which the sheath consists of the first component of an ethylene-propylene random copolymer and the core consists of the second component of a polypropylene or a structure of the both components placed side by side, or a conjugate fiber in which two kinds of polyester polymers having different shrinkages are placed in an eccentric sheath-core structure or a side- by-side structure. Further, the crimping synthetic fiber has a shrinkage of >=14% and is capable of exhibiting 10-20 steric crimps for every one inch.  Subsequently, the obtained short-fiber web is laminated on one side or both sides of a spunbonded nonwoven fabric and the laminate is treated by a high-pressure water-flow treatment to integrate under entanglement. Thus, the objective bulky nonwoven fabric having a specific volume of >=17cm<3> /g at a load of 3g/m<2> is obtained.

Filed: 1979-10-25
Abstract: PURPOSE:To make the size of a memory smaller by a method wherein a complementary connecting inverter which is a P and N channel element with N type polycrystalline Si as a gate is used as an input circuit, while a pair of P channel composed of P type polycrystalline Si and N channel composed of N type polycrystalline Si are used for a circuit inside the memory.

Of these two elements, the circuit inside the memory consists as usual of a P channel made of P type crystalline Si and an N channel of N type crystalline Si. Although the input circuit is constituted by an inverter in which P and N channel elements are complementary connected, gate electrodes 211 and 212 to be provided with the elements are not to be used separately depending upon the types P and N, but formed with the N type polycrystalline Si uniformly. By so doing, the threshold voltages of the two elements become approximately the same, while the input circuit can be made smaller without reducing the response speed.
