Title: Biaxial orientation blow molding method and preform holding jig
Inventor: SEKI NOBUICHI
IPC: B29C49/58
Filed: 1995-04-28
Abstract: The present invention is intended to prevent the deformation of a cylindrical mouth portion of a preform when a blow pressure acts thereon in a diameter expanding direction during biaxial orientation blow molding.  During biaxial orientation blow molding, sealing of the blow pressure is accomplished by means of a neck ring P1 circumferentially provided on a lower end of the circumferentially provided on a lower end of the circumferential surface of a cylindrical mouth portion P2 of a preform to thereby make the blow pressure act uniformly on the whole area of the cylindrical mouth portion P2, whereby the unreasonable deformation of the cylindrical mouth portion P2 due to the ununiform application of blow pressure thereto can totally be eliminated.

Each battery monitoring module will monitor a number of batteries, and the current carrying wire (38) between them, so that incipient problems may be detected before failure or significant damage occurs. A serial communications bus (24) is provided between the main control module and the battery monitoring modules, and data transmitted over that bus is generally digitally encoded. Sensitive analog circuitry in the battery monitoring modules is located in proximity to the battery modules with which it is associated, and is galvanically isolated from the digital communication circuitry and the data communications bus transmitting the data to the main control module. Any switching or other controllers in the battery are galvanically isolated from the battery monitoring modules and the main control module. Means (70) are provided to isolate specific cells or battery modules, as required; other means are provided to ensure that important voltage and/or current samplings are indicative of equilibrium of the electrical charge or discharge reactions, so that erroneous readings taken during fast acceleration or braking, or other circumstances except essentially steady state conditions, may be discarded. Other means are provided whereby the driver of an electric vehicle receives warnings as the available energy still within the battery depletes below specified levels; and further means are provided to ensure that rate of discharge or regenerative charging of the battery do not exceed predetermined limits.
