Title: Metallic mold for rear extrusion
Inventor: NAKANO TAKASHI
IPC: B21C25/02
Filed: 1984-04-26
Abstract: PURPOSE:To obtain a titled metallic mold for improving the working accuracy and its life by providing a guide bush for guiding a punch, so as to be freely liftable, guiding the punch in the vicinity of a die, and preventing the eccentricity and breakdown of the punch. CONSTITUTION:First of all, air is fed to an air cylinder 17 of a punch 11, and a plate 14 is energized downward through a piston 18. When the punch 11 having a punch 12 whose tip part is slightly thick is lowered, the plate 14 also descends together with the punch, and the punch 12 and a guide bush 13 for guiding its axial part so as to be freely slidable descend in the same related position. When the punch 11 is lowered after the bush 13 has been fitted by prescribed length into a center hole 7 of a die 8 of a die 5, the punch 12 descends by a guidance of the bush 13, and a blank 6 is pressed and formed. In this regard, the cylinder 17 descends together with the punch 11, but a piston 18 lifts relatively in a state that it remains stopped, and energizes the plate 14 downward. Also, the cylinder 17 sets in advance the upper limit position of the punch 12 to a state led slightly into the bush 13.

Abstract: PURPOSE:To eliminate a sense of incongruity of a reproducing sound in case a noise is being generated, by executing a noise elimination processing of a sum signal, executing a reverberation addition processing to the sum signal which has been brought to the noise elimination processing and generating a pseudo difference signal. CONSTITUTION:In case of a normal state, a coefficient K of each multiplier 7-10 is set to '1' and the multiplier 7 and 8 are made to conduct, the multiplier 9 and 10 are cut off, and an L+R signal (sum signal) and an L-R signal (difference signal) of a converter IC 3 are led directly to a multiplexer 4. On the other hand, when a noise has been generated, the coefficient is set to '0' extending over the whole period in which the noise has been generated and the multiplier 7 and 8 are cut off, and the multiplier 9 and 10 are made to conduct, by which an L+R signal from a noise eliminating circuit 5 and a pseudo L-R signal from a reverberation adding circuit (a system of a shredder) 6 are led to the multiplexer 4, respectively. In this way, light and left output signals L, R which are separated by the multiplexer 4 become those which have a pseudo stereo reproducing sense.
