Title: Signal reproducing circuit
Inventor: UCHINO SEIJI
IPC: H04L27/227
Filed: 1989-01-30
Abstract: PURPOSE:To reproduce more stable clock and carrier wave with a simple circuit constitution by controlling the gain of an IF amplifying circuit so that the output of an LPF always coincides with a set voltage. CONSTITUTION:An output signal as the even function of an input signal is outputted from a nonlinear circuit 2 to which the output of an IF amplifying circuit 1 is supplied. A BPF 4 extracts a first frequency component (clock frequency component) included in the output signal of the nonlinear circuit 2 and outputs it, and a BPF 5 extracts a second frequency component (higher harmonic component of carrier frequency) and outputs it. Meanwhile, an LPF 3 extracts only a DC component included in the output signal of the nonlinear circuit 2. A control circuit 6 integrates the differential voltage between the output of the LPF 3 ad a preliminarily set voltage to generate a control signal. The gain of the IF amplifying circuit 1 is controlled by this control signal so that the output of the LPF 3 always coincides with the set voltage.

IPC: B21D22/02
Filed: 1984-02-10
Abstract: PURPOSE:To improve yield by making drawing using a die and a punch by holding only opposite edges of one direction out of edges of a blank. CONSTITUTION:A panel W is supported by die faces 13b, 13b on a die 13. When a blank holder 11 is lowered, beats 11c of blank holder faces 11b, 11c come into contact first with the panel W, and only opposite edges of smaller inclination side are held by the blank holder face 11b and die face 13b.

Title: Audio data decoder
Inventor: SATOU HISAAKI
IPC: H04N19/59
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To improve reproduction of audio data through the use of a D/A converter with a simple configuration by providing an interpolation data generating means to interpolate basic time base information through the similar arithmetic operation to that of a frequency/time conversion means in the case of reproducing audio data. SOLUTION: A multiplexer means 3 conducts multiplex processing between basic time base information generated by a frequency/time conversion means 1 and interpolation data generated by an interpolation data generating means 2. Digital decoded audio data are generated by applying prescribed processing to the output data from the multiplexer means 3. Furthermore, interpolation data are generated simultaneously in addition to basic time information according to the coding standard by applying finer setting to a processing rate of the frequency/time conversion than the processing rate according to the standards. Thus, many interpolation data are obtained by using a finner rate without the use of a complicated 1-bit D/A converter system to obtain the interpolation data.
