Title: Injection-molding die and method for molding injection-molded product using this die
Inventor: HIRAIWA NAOKI
IPC: B29C45/14
Filed: 2002-10-02
Abstract: <P>PROBLEM TO BE SOLVED: To provide an injection-molding die which diminishes the positional deviation of an insert component and a method for molding an injection-molded product using this die.  <P>SOLUTION: In the injection-molding die equipped with a holding pin 5 for holding the lead part 2b of an insert component 2 arranged at a specified position inside a cavity 3 and a drive part 6 for moving the holding pin 5, the drive part 6 moves back the holding pin 5 from the cavity 3 before the holding pin 5 comes into contact with a resin 9 after the start of injecting the resin 9 into the cavity 3. In this case, the holding pin 5 moves along its contact face with the lead part 2b while being kept in contact with the lead part 2b. Thus the holding pin 5 keeps the lead part 2b in its contact with the latter during receding from the cavity 3, so that the positional deviation of the insert component 2 from the lead part 2b on account of the injection of the resin 9, is diminished.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To newly provide a method for vector control and a device using the same without requiring a position detector such as an encoder so as to solve various problems caused by the position detector such as the encoder mounted to a rotor in a method for drive control of a permanent magnet synchronous motor and a device using the same.  <P>SOLUTION: A minimum dimension state observer 12a is driven by utilizing signals of a stator current and a stator voltage in a phase determiner 12. In addition to this, the minimum dimension state observer estimates a rotor magnetic flux phase on a rotary dq coordinate system by utilizing a rotation speed of the rotary dq coordinate system and an estimated value of the rotor speed, and outputs it toward a phase synchronizer 12b. An estimated value of the rotor magnetic flux phase viewed from a fixed αβ coordinate system, an estimated value of the rotor speed as its differential value, and a rotation speed of the rotary dq coordinate system are generated and outputted in the phase synchronizer. The problems are solved by utilizing the estimated value of the rotor magnetic flux phase for the vector control instead of position signals by the position detector.  <P>COPYRIGHT: (C)2004,JPO
