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.

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.

A solid golf ball comprising a core and a cover has a number of dimples in its surface. The core has a deflection of 3.5-5.5 mm when under a load of 100 kg, and has a JIS-C hardness at its surface of at least 70 and a JIS-C hardness at its center which is at least 10 units lower than the hardness at the core surface. The ball, when hit with a driver at a head speed of 50 m/s, has an effective contact area A and an apparent contact area B with the club face such that the ratio A/B is from 0.40 to 0.60. The ball has a soft feel, fully adequate spin characteristics, and excellent control on approach shots, and is well suited for use by golfers having a head speed of less than about 40 m/s.

A host computer logs in an image providing device such as a scanner connected by a serial bus, and reverses flow control of data transfer by issuing a Reverse command. The image providing device opens a transfer channel by an OpenChannel command, transfers image data in form of blocks. When the transfer of the image data has been completed, the image providing device closes the transfer channel by a CloseChannel command, and reverses the flow control of the data transfer again by the Reverse command. This changes the data transfer direction of a device having a bi-directional data transfer function, i.e., a device having a data reception function and a data providing function.

An optical disc has a plurality of tracks for recording information represented as marks and spaces between the marks. The marks are formed by an optical beam modulated by a plurality of drive pulses (202) where a number of the drive pulses is determined according to a length of a mark part in the original signal to be recorded to the track. The optical disc has a control information recording area (2504) for storing a first pulse position Tu value indicative of rising edge of the first drive pulse for determining a start position of a mark to be recorded, and a last pulse position Td value indicative of falling edge of the last drive pulse for determining an end position of a mark to be recorded.
