IPC: G11B21/10

Abstract: PURPOSE: A head control unit of a disk apparatus is provided to precisely detect the locative deviation from the center of a track and the location of the head while not generating a searching error even if a phase difference between two phase-detecting outputs contains a tolerance error. CONSTITUTION: A detector obtains two detecting outputs having different phases. The location deviation from a present head location to the center of a track is obtained based upon an analog method. The head location of the track is obtained, based upon a digital method, by combining the polarities of phase-A output and phase-B output. When the head moves by an external impact and the outputs exceed a maximum point, the area of the head on the track is decided by using the polarities of the phase-A output and the phase-B output. Herein, the outputs of the phases possibly contain the relative phase-shift tolerances. Thus, a dead zone is supplied for fixing a detected value for precisely detecting the head regardless of the phase-shift.

Abstract: PURPOSE: A heat exchange structure for a send/receive module is provided to improve heat exchange effect by exposing a heat exchange unit of the send/receive module to the outside from the bottom of the body of a terminal. CONSTITUTION: A wireless terminal case consists of a cover(10) and body(14). An end/receive module is mounted on a heat exchange unit(18). A concave portion(24) is formed on the bottom(22) of the body(14). The exchange unit(18) is mounted to the concave portion(24) so that it can be exposed to the outside. Accordingly, ambient air and heat generated from the send/receive module(12) are exchanged at the heat exchange unit(18) exposed to the outside. By this heat exchange structure of the send/receive module, the heat exchange unit(18) is exposed to the outside and thus emits heat generated from the send/receive module(12) to the outside directly, so no blow hole is needed at the body(14) of the terminal and heat emission effect becomes excellent.

The multiplexer selectively performs an outputting operation based on the conversion signal(RVRS) after receiving a complement signal and a delaying signal from the data delaying unit. The receiver(200) is composed of the first and second de-flipflops and a multiplexer. The first de-flipflop synchronizes parallel data(d<n-1:0>) to a clock signal(clk) after receiving the data, and then outputs a delaying signal and a complement signal according to the synchronization. The second de-flipflop synchronizes a conversion signal(RVRS) to the clock signal(clk) after receiving the signal, and then outputs the synchronized clock signal. The multiplexer selectively performs an outputting operation on the basis of the outputting signal of the second de-flipflop after receiving the delaying and complement signals from the first de-flipflop.
