    摘要： A polyolefin rubber composition consisting essentially of 100 parts by weight of a polyolefin rubber polymer, 10 to 100 parts by weight of a mono-olefin monomer, 1 to 20 parts by weight of a polyolefin polyfunctional monomer, and 0.1 to 15 parts by weight of an organic peroxide, wherein these components are blended and subjected to heat treatment to form a denaturated polyolefin rubber.The mechanical and electrical characteristics of this denaturated polyolefin rubber do not deteriorate even after long-time subjection to heat treatment, and this material finds application as a rubber for thermally resistant electrical products.

    摘要： The present invention is directed to provide a magnetic head that is capable of effectively preventing TA noise.A slider 1 is provided with air bearing surfaces 111 and 121. Electromagnetic conversion elements 2 and 3, which are provided toward the trailing edge TR of the slider 1, perform electromagnetic conversion at the air bearing surfaces 111 and 121. The slider 1 is provided with indented portions 114 and projecting portions 115 at the air bearing surfaces 111 and 121 where the electromagnetic conversion elements 2 and 3 are provided. The indented portions 114 are provided in the areas corresponding to the width W2 of the electromagnetic conversion elements 2 and 3 viewed in the direction of the track width further toward the trailing edge TR than the electromagnetic conversion elements 2 and 3. The projecting portions 115 are provided adjacent to the indented portions 114 further projecting out compared to the indented portions 114.

    摘要： There is disclosed a magnetic head device in which a head IC chip may be located relatively closer to a magnetic head and a thermal effect may be controlled to be within a range of acceptable degree. Said magnetic head device comprises a head slider having a magnetic head, a suspension member which is made of thin resilient material and supports the head slider at one end thereof, and a head IC chip, wherein the suspension member is attached to other member at the other end thereof. The IC chip is mounted on the suspension member. When the IC chip is selected to have appropriate disc side area and is mounted on the suspension member, the temperature of the IC chip itself may be maintained within a range of acceptable degree and that of the magnetic head may be also kept to be lower. When the electric power consumption of the IC chip is equal to or less than 410 mW, the disc side area thereof should be equal to or more than 1.1 mm2. The IC chip is mounted on a surface of the suspension member at a side facing to the disc at a position where a relative linear velocity equal to or more than 25 m/sec is generated with respect to said disc.
