IPC: G11B20/00
Filed: 1987-04-13
Abstract: PURPOSE:To eliminate only a DPSK signal in an excellent way by providing a BPF extracting the DPSK signal and an arithmetic circuit adding or subtracting the DPSK signal from the BPF to/from a multiplex signal between the DPSK signal and an FM color difference signal. CONSTITUTION:A delay time of the BPF 36 is a half the period (t) of the carrier wave of the DPSK signal. The arithmetic circuit 42 is an arithmetic circuit summing an output of an LPF 8 and an output of the BPF 36. The component of the DPSK signal in the output signal of the LPF 8 is shown in a figure (b). A signal retarded by a half period more than the signal shown in a figure (b) is outputted from the BPF 36 as shown in a figure (c). The component of the DPSK signal outputted from the arithmetic circuit 42 is shown in a figure (d). A noise N1 is produced in 2.44musec from the point of time of data switching, but the component of the DPSK signal is eliminated in an excellent way during the period other than the said period.

Filed: 1983-05-25
Abstract: PURPOSE:To effectively dissipate heat from an LSI by forming a substrate of a silicon carbide. CONSTITUTION:A package for a semiconductor device has a substrate 1 which includes a main surface directed toward the upside of the drawing. This substrate 1 is formed of a silicon carbide. Metallized films 2, 3 are formed by a normal method at the prescribed positions on the substrate 1. The film 2 is covered on a central region to be mounted with a semiconductor device of the main surface, while the film 3 is formed on a peripheral region which surrounds the film 2, and forms a soldered part for soldering. When a LSI is actually bonded on an element bonding part 2 of the package, heat produced at the LSI operating time is transmitted through a metal layer of the bonded part 2 to the substrate 1. Since the substrate 1 has a high thermal conductivity, the heat from the LSI is efficiently dissipated through the substrate 1.

Filed: 1992-03-18
Abstract: PURPOSE:To improve an error rate by providing two D-type FFs, a clock regenerating means, and a discrimination and regeneration circuit, and generating a reference clock by using a data reproducing clock and two outputs of a second FF pair. CONSTITUTION:Detected output is obtained by phase comparators 1, 2, and this output is inputted to the DFFs 3, 4 of a succeeding stage, and H or L is decided at the rise-up of a clock obtained by inverting the clock of a preceding stage by inverters 17, 18. At that time, the period of time of analog displacement in the outputs of the FFs 1, 2 is sufficiently small compared with a clock period. Accordingly, when the outputs of the FFs 1, 2 are decided at the rise-up of the clocks obtained by inverting the clocks of the FFs 1, 2 by the inverters 17, 18, sufficient time to spare is generated in the set-up time and the hold time of the FF. Therefore, the analog displacement is eliminated, and the output of the phase comparator with few jitters is obtained, and this is connected to the improvement of the error rate.
