摘要:
An information processing apparatus includes a communicating section that executes communication with a server, a local storage section that stores subsequent data acquired from the server, and a data processing section that executes an acquisition process of the subsequent data, and a data playback process using data stored on a disc and the subsequent data stored on the local storage section. The data processing section builds a virtual file system for reading data stored on the disc and the local storage section, at the time of the data playback process, and performs the acquisition process of the subsequent data by transmitting a package ID to the server at the time of the acquisition process of the subsequent data, the package ID being information specifying a package corresponding to a file set necessary for building or updating the virtual file system.

Described embodiments receive a signal by a set of fixed taps and a set of floating taps of a receiver, each tap corresponding to a detected symbol. Each of the floating taps is stored in a corresponding shift register to account for process, operating voltage and temperature (PVT) variations of the receiver without calibration of delay elements. Multiplexing logic selects (i) corresponding floating taps for equalization by coupling selected floating taps to the outputs of the fixed taps, and (ii) different phases of each possible floating tap position. The multiplexing logic prunes and/or amalgamates the phases of each possible floating tap position and selects floating taps based on a magnitude of each phase. A combiner adjusts each output value of the fixed taps and the selected floating taps by a corresponding tap-weight, combines the adjusted values into an output signal and subtracts the output signal from the input signal.

There is disclosed a method of producing a pre-oxidation fiber in the production of the pre-oxidation fiber by subjecting a polyacrylic precursor fiber to pre-oxidation processing in an oxidizing atmosphere, including shrinking the precursor fiber as a pretreatment of pre-oxidation at a load of 0.58 g/tex or less in the temperature range of 220 to 260° C. under conditions in which the degree of cyclization (I1620/I2240) of the precursor fiber measured by a Fourier transform infrared spectrophotometer (FT-IR) does not exceed 7%, initially-drawing the precursor fiber at a load of 2.7 to 3.5 g/tex in an oxidizing atmosphere at 230 to 260° C. in the ranges of the degree of cyclization of not exceeding 27% and of the density of not exceeding 1.2 g/cm3, and then subjecting the pre-oxidation fiber to pre-oxidation treatment. A carbon fiber of high strength and high elasticity that is appropriate for composite materials that exhibit high composite performance is obtained by continuously subjecting this pre-oxidation fiber to carbonization treatment.
摘要:
A linear relationship is established between a gain control signal and an amplification factor (value in dB). Described is a current generation circuit including a first current output section which outputs a first current, a second current output section which outputs a second current proportional to the first current, and a variable-current control section which generates a third current proportional to the first current, divides the third current into a fourth current and a fifth current according to a first control signal, and outputs the fourth and the fifth currents. The current generation circuit outputs a sum of the first and the fourth currents as a reference current, and a sum of the second and the fifth currents as an output current.
