Title: Adaptive type predicitive encoder
Inventor: NAKAMURA MAKOTO
IPC: H03M7/32
Filed: 1982-04-16
Abstract: PURPOSE:To simplify the entire scale and to improve the S/N of a reproducing signal, by using a predictive filter taking partial autocorrelation and spectrum versus parameter as coefficients for both an adaptive type predictive encoder and an encoder. CONSTITUTION:A predictive coefficient is extracted by an analysis circuit 37 from a signal Sn supplied to a terminal 31 and it is applied to a predictive filter 36 at the transmission side and a predictive filter 45 at the reception side, respectively. A substractor 34 performs subtraction between signal Sn set from the terminal 31' and a signal Sn' sent from an adder 35 and supplies an output signal 6n to an encoder 33 for quantization and then to a decoder 43 at the reception side vai a terminal 38. An output signal 6n' is outputted to an adder 35 via a decoder 34 at the transmission side. The adder 35 adds the signal 6n' to an output signal gamman of the filter 36 and gives the result to a subtractor 32 as a predictive signal sn'. The signal of a decoder 43 is added to an output signal of the filter 45 and the added signal is outputted as a reproducing signal from a terminal 46.

Abstract: PURPOSE:To omit the step of removing a burr from a molded product after upper and lower molds are opened by pressing only the product butting surface of one mold on only the other butting surface of the other mold, thereby automatically separating the burr part except the rubber product from the butting surfaces of the molds at the molding time. CONSTITUTION:After unvulcanized rubber is filled in the cavity 4, 5 of molds 1, 2, a push plate 12 and a bearing plate 13 are pressed to contact each other, a ring 6 is pressed to a ring 9, and they are heated. Then, the rubber in the cavity 4, 5 is partly swelled out as rubber burr from the butting surfaces 3, 16. An upper base mold 7 and the ring 8 isolate from the butting surfaces 3, 6 via the rubber burr, float and stops moving when they contact with the push plate 12. After the rubber is completely vulcanized, the molds 1, 2 are opened. Then, the peripheries 14, 15 of the product bear concentrated compression force from the first. Accordingly, the rubber burr and the product have already been separated, and the step of individually removing the rubber burrs can be omitted.
