    摘要: A single-pole type magnetic head for perpendicular recording which reduces the amount of side writing even in the presence of a yaw angle and prevents the effective track width from decreasing, and a magnetic recording disk apparatus using the same. A main pole is composed of at least two portions where the width of the first portion continuously increases from the upstream side to the downstream side in the medium moving direction and the width of the second portion is the same as the width of the first portion's downstream edge in the medium moving direction and is constant from the upstream side to the downstream side in the medium moving direction. This prevents the recording magnetic field strength from decreasing at the track edge and increases the effective track width while suppressing side writing, thereby realizing a magnetic recording disk apparatus with a high track density.

    摘要: In a bus network wherein a plurality of devices are interconnected, the devices share an address space that they can access. The position information describing the actual locations of the devices, and the functional information for the devices are stored in a predetermined area in the address space. When a specific device on the network displays information in the address space for each device, a user can easily specify the actual location of a desired device that is connected to the network, and can also identify the functional information for the device.

    摘要: Even with an asymmetric reproduction waveform, or under the noisy environment, an accurate equalizing error is found and temporary judgment value for adaptively controlling the coefficient of FIR filter is accurately outputted. A waveform equalizer for equalizing a waveform of a reproduction signal obtained by reproducing marks and non-marks recorded on a recording medium is provided. The equalizer includes: a detector which detects asymmetry of the reproduction signal arising from physical profiles of the marks and non-marks and outputs a detection signal representing asymmetric amount; a discriminator which discriminates the marks and non-marks based on the reproduction signal to output a discriminated signal; and a selector which calculates a first and second coefficient multiplied by the reproduction signal of the marks and non-marks based on the detection signal, which are different. The selector selects one of the first and second coefficients based on the discriminating signal.

    摘要: In a multi-piece golf ball comprising a core, an intermediate layer, and a cover, the ratio of A/B is set to be 1.10/1 or greater wherein A is a deflection under a load of 100 kg of the core and B is a deflection under a load of 100 kg of a sphere having the core enclosed with the intermediate layer, and the coefficient of restitution of the ball at a firing velocity of 25 m/s minus the coefficient of restitution of the ball at a firing velocity of 50 m/s is less than 0.100. The ball shows performance less dependent on a head speed, a distance exactly corresponding to a particular number of club used, and improved flight performance at a high head speed.
