A fluid coupling power transmission is constructed such that a pump impel let and a turbine runner are arranged to face each other in a housing, to which torque is inputted, and such that a lockup clutch is disposed in the housing for transmitting the torque from the housing to the turbine runner. The fluid coupling power transmission comprises: a damper mass made rotatable relative to the housing and arranged at the side facing the pump impeller across the turbine runner; an elastic member adapted to be compressed by the revolution of the, damper mass relative to the housing; a lockup piston interposed between the damper mass and the turbine runner and pushed by oil pressure toward the damper mass into selective engagement with the damper mass; a first oil pressure chamber adapted to be fed with the oil pressure for pushing the lockup piston toward the damper mass; a second oil pressure chamber formed between the lockup piston and the damper mass, when the lockup piston engages with the damper mass, and adapted to be fed with oil pressure for separating the lockup piston from the damper mass; and a reaction mechanism for applying a reaction to the damper mass In a direction to separate the damper mass from the housing against the force for the lockup piston to push the damper mass.

A head suspension prevents a read element from electrostatic discharge damage without employing a static electricity remover, and at the same time, secures the frequency characteristics of a write signal. The head suspension has a load beam to apply load to a slider that writes and reads data to and from a hard disk, a flexture made of a conductive thin plate attached to the load beam, to support the slider, write wires connected to the slider and formed on an insulating base layer that is made of flexible resin and is formed on the flexure, and coating made of conductive flexible resin to discharge static electricity. The coating is formed over the read wires and is extended to the surface of the flexure.

A wired flexure comprises a metallic substrate, a polyimide layer formed on the metallic substrate, and read conductors and write conductors formed on the polyimide layer. The polyimide layer has a thick-walled portion and a thin-walled portion that are different in thickness. The read and write conductors extend covering the thick- and thin-walled portions. In order to obtain a desired impedance, the width of the conductors in the thin-walled portion is smaller than that of the conductors in the thick-walled portion.

In a mask ROM device, a plurality of recesses extending parallel to each other are formed in a memory cell array region on the surface of a silicon substrate. In the direction intersecting the recesses, first and second transistor trains are formed in which select transistors and memory transistors are connected in series. The MOS transistors of the transistor trains have the sidewall of recess 5 formed as a channel region. A depletion implantation layer corresponding to data to be stored is formed on the sidewall of the recess. The first transistor train and the second transistor train are insulated and isolated from each other by an LOCOS isolation film.

The yarn is improved in modulus and shrinkage. A textile reinforcement for tire cord obtained from the multifilament yarn, exhibits exceedingly improved resistance to fatigue and durability to heating. The polyester multifilament yarn is obtained by (A) melt-spinning polymer at high speed (B) solidifying the spun yarn through a solidification zone comprising (a) a heating zone and (b) cooling zone adjacent to the lower part of the heating zone, and (C) withdrawing the solidified yarn, and (D) hot drawing the yarn.
