摘要:
A MR magnetic head with a sensing element which comprises a plurality of superposed magnetic layers which have a magnetoresistance effect in at least one and a nonmagnetic intermediate layer sandwiched between the magnetic layers, and a sensing current is fed so as to flow in the sensing element in the same direction as a signal magnetic field which is applied to the element. Each of the magnetic layers is formed so as to have an easy axis of magnetization which is substantially perpendicular to the signal magnetic field or to have an isotropic magnetic characteristic in the magnetic film plane, which eliminates Barkhausen noise.

A magnetic disc has a magnetic recording area on or from which the information may be recorded or reproduced by a recording head loaded on a slider. The magnetic recording area has a data area including a recording track as a crest and a guard band as a valley, and a servo area having servo marks as crests and valleys. A CSS area for contact-start-stop (CSS) with the slider is made up of CSS data areas radially consecutive to the data areas and CSS servo areas radially consecutive to the servo areas. The entire surfaces of the CSS servo areas may be planarized at the same height level as the recording tracks. The CSS servo areas are provided with the same pattern of crests and valleys similar to that of the data areas. This suppresses generation of powder debris during CSS while optimizing the amount of float of the slider and the floating posture in the CSS area.

A tire having superior cut resistance and less belt separation comprising a tread with steel cord belts in which a center rubber for middle part of the tread and a side rubber for both sides thereof are respectively formed of different rubber compositions, and in which at least an inner portion of the center rubber is composed of a rubber composition of superior cut resistance wherein either a natural rubber of a SBR blended natural rubber is compounded with carbon black of large iodine absorption number, silica and silane coupling agent expressed by a formula of (OR).sub.3 SiCnH.sub.2 nSmCnH.sub.2 nSi(OR).sub.3 or (OR).sub.3 SiCnH.sub.2 nX, while the side rubber is composed of a rubber composition having small heat build up.
摘要:
Method for measuring resistance to slippage comprising the steps of mounting a sample of rubber at the bottom of a pendulum freely swinging on a shaft, sliding the sample of rubber along a road surface sample which is either dry or wet during swinging of the pendulum, measuring kinetic energy loss of the pendulum due to sliding of the sample thus obtaining resistance to slippage, in combination with the step of either heating or cooling the sample of rubber to a predetermined temperature for performing the method.
摘要:
There are provided a cooling device and a heat sink that can effectively radiate heat generated by a heat source while reducing the volume of discharged gas to avoid noise, and an electronic apparatus in which the cooling device and the heat sink are mounted. A heat sink 3 includes cutouts 24a and 24b through which air serving as gas can be taken in from the outside and which are provided on a side where air discharged from first and second nozzles 6 and 7 serving as openings of a jet generating mechanism 2 is received. Therefore, the pressure near the cutouts is decreased by air flow discharged from the first and second nozzles 6 and 7, and outside air is taken in through the cutouts 24a and 24b. Consequently, more gas than gas discharged from the first and second nozzles 6 and 7 is discharged from an outlet of the heat sink. This can minimize the volume of jetted gas to avoid noise, and effectively radiate heat generated by a heat source.
