Title: Biaxially oriented polyester film
Inventor: MINAMIZAWA HIDEHITO
IPC: C08L67/02
Filed: 1990-06-26
Abstract: PURPOSE:To obtain a biaxially stretched polyester film satisfying the compatibility of the damage of a magnetic surface and the frictional characteristic with a resin guide pin by setting the sphericity, mean particle size, content and thickness orientation index of calcium carbonate particles in a film to specific ranges. CONSTITUTION:A biaxially oriented polyester film contains 0.002-10.0wt.% of spherical calcium carbonate particles having sphericity in the film of 1.5 or less, a mean particle size of 0.010-5.00mum and a thickness orientation index of 1.20 or less. When the sphericity is larger than the above-mentioned range, the frictional characteristic with a resin guide pin becomes inferior and, when the mean particle size is smaller than the above-mentioned range, the frictional characteristic with the resin guide pin becomes inferior and, when the mean particle size is larger than said range, a magnetic surface becomes inferior. When the content is larger than the above-mentioned range, the frictional characteristic with the resin guide pin becomes inferior and, when the content is larger than said range, the magnetic surface becomes inferior. Further, when the thickness orientation index exceeds 1.20, no effect is obtained.

Abstract: PURPOSE:To simplify the construction of a brake gap adjust device for car by setting a flank angle on the forward end side of an adjuster screw larger than that on the trailing end side thereof, and engaging the adjuster screw with a nut by a multiple thread screw reversible in one direction. CONSTITUTION:A multiple thread screw 15 for engaging an adjuster screw 24 with an adjuster nut 25 has a flank angle alpha on the forward end side of the adjuster screw 24 which is set larger than a flank angle beta on the trailing end side thereof to be reversible in one direction.

Title: Semiconductor memory device
Inventor: YAMADA TOSHIRO
IPC: G11C11/409
Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To maintain a long data holding time and obtain a long refresh cycle period even if a little current leakage from a memory exists. SOLUTION: Memory cells 11-15 and 2 are connected to a word line WL. The information memory cells 11-15 are inputted one side input terminals of sensing amplifiers SA1-5 through bit lines bit1-5. The reference information corresponding to the reference potential of information reading is stored in another memory cell 2. The reference information is inputted to the other side input terminals of the sensing amplifiers SA1-5 in common through a bit line bit7. Therefore, even if the potentials of signal charges stored in the respective information memory cells 11-15 are declined by a leakage current, since the potential of the signal charge stored in the memory cell 2 in which the information of the reference potential is stored is also declined accordingly by the leakage current, a time required for the potential difference between them to reach the sensing limit is extended and a long data holding time can be obtained.
