摘要： An equalizer equalizes a reproduced waveform reproduced by a thin film magnetic head by reproducing information recorded magnetically on a medium. In the equalizer, the reproduced waveform is delayed to a position of an undershot portion, and is attenuated to an amplitude corresponding to a magnitude of the undershot portion, and the resultant waveform is superposed on the reproduced waveform, to thereby eliminate the undershot portion. Furthermore, by superposing a waveform obtained by inverting the reproduced waveform and amplifying or attenuating the inverted waveform, on the reproduced waveform at a half power position thereof, the width is narrowed.

摘要： A magnetic head for reading-out information magnetically recorded on a magnetic recording medium in a waveform varying between two different phases. The magnetic head includes at least one block of high magnetic permeability disposed adjacent to and directly facing a surface of the magnetic recording medium to be read-out so as to provide a magnetic path for passing therethrough magnetic flux emanating from the magnetic record on the magnetic recording medium. A magnetic material member is disposed adjacent to the at least one block so as to cause the magnetic flux emanating from the magnetic record on the magnetic recording medium to pass therethrough and is responsive to transition of the magnetic flux corresponding to variation from one phase to another phase in the waveform representing the recorded information so as to provide a predetermined physical effect. Further, a detecting arrangement is provided for the detecting the predetermined physical effect.

摘要： The invention relates to a method for transmitting power headroom information from a user equipment to the base station. The transmission is made dependent on scheduling type of the uplink resource, for which the power headroom information is to be calculated and over which it is to be transmitted. If the uplink resource is dynamically scheduled, then the extended power headroom report according to Rel. 10 is transmitted; if it is scheduled persistently, e.g. as part of a semi-persistent scheduling configuration, then a basic power headroom report according to Rel. 8/9 is transmitted. The invention circumvents the problem of delaying data in persistently allocated uplink resources when transmitting an extended power headroom report.

摘要： A temporary assembly apparatus includes a support member for supporting heat exchange tube blanks having their lengthwise direction positioned laterally, with their widthwise direction positioned vertically. Header supports are arranged respectively at the left and right sides of the support member and movable leftward or rightward. Tube blank correcting members are each in the form of a plate having slits formed in a side edge thereof and arranged from the front rearward at the same spacing as the heat exchange tubes to be produced. Each of the blank correcting members is movable between a correcting position where the corresponding ends of the tube blanks as supported on the support member are fitted into the respective slits and a noncorrecting position where the tube blanks are not fitted into the slits.
