Title: Prevention of reverse rotation of screw of injection molder
Inventor: SAKAUCHI SABURO
IPC: B29C45/76
Filed: 1986-04-08
Abstract: PURPOSE:To prevent a screw rotation at a linear movement, by outputting on a motor control section which controls an electric motor just before an injection or a suck-back operation in order not to rotate the motor. CONSTITUTION:Accompanied with the rotation of a screw 11, the screw 11 is moved backward because a resin is stocked in the lefthand side of a heating cylinder 12. The rotation is stopped when the quantity of the resin becomes good enough to be determined, and then the screw 11 is moved a bit backwards as a suck-back by means of a driving mechanism 15 is order to prevent a nozzle 12A from drilling. Next, at injecting, the resin stocked in the lefthand side of the heating cylinder 12 is injected into a mold by moving the screw 11 forward. Just before a suck-back and an injection operations, '0 rotation' is output on the motor control section of 'Position control' is output to fix the position of rotating direction of the screw 11 at the start of injection. Because the motor 17 would not thereby rotate even if it got a driving force, the screw 11 would not rotate even if it got a counter-force of the injection operation or etc.

Abstract: PURPOSE:To simplify the circuit and to avoid load to the demodulator by calculating the absolute phase of a polyphase modulation wave without using a discriminator, multiplying number of phases with the absolute phase and detecting the phase error. CONSTITUTION:A 1st multiplier 1 multiplies the in-phase component of the polyphase modulation wave with the polyphase modulation wave and a 2nd multiplier 2 multiplies the orthogonal component of the polyphase modulation wave with the polyphase modulation wave.
