Abstract:
Disclosed is an injection molding device and process for a test tube shaped preform, that can laminate a colored layer at certain positions with a certain thickness accurately. Included is a nozzle section, in which a molten main resin and second resin are joined together to form a joined resin mass, the nozzle section including: an outer flow channel through which the main resin flows, an inner flow channel through which the second resin flows, a cylindrical column-shaped flow channel where the second resin joins the main resin, a first confluence where the main resin flows into the joined flow channel, a second confluence where the second resin flows into the joined flow channel wherein the first confluence is downstream of the second confluence, and a cylindrical shutoff pin inserted in the joined flow channel to open or close one or both the first and second confluences.
Abstract:
Technical problems of this invention is to create an injection molding device and an injection molding process for a test tube shaped preform, that can laminate a colored layer at certain positions of a wall of the reform with a certain thickness in a manner of a high degree of accuracy.A feature associated with the injection molding device to solve these problem comprising a nozzle section, in which a molten main resin and a molten second resin are join together to form a joined resin mass, the nozzle section comprising: an outer flow channel through which the main resin flows, an inner flow channel through which the second resin flows, a cylindrical column-shaped joined flow channel where the second resin from the inner flow channel joins the main resin from the outer flow channel, a first confluence disposed at a point where the main resin from the outer flow channel flows into the joined flow channel, a second confluence disposed at a point where the second resin flows into the joined flow channel wherein the first confluence is located downstream of the second confluence with a predetermined space left in between, and a cylindrical shutoff pin inserted slidably in the joined flow channel, wherein this shutoff pin is capable of shutting off or opening either or both of the first confluence and/or the second confluence, depending on the sliding position.

Abstract:
An electrical apparatus, which is immovable in a facility, comprises plural electric circuits. Each electric circuit has one or more resistance elements and is connected to each input terminal connected a power source. The electric circuits are arranged positionally closely with each other. In each electric circuit, a desired functional circuit is connected in series to the resistance element, and a protection circuit is connected in series to the resistance element and connected in parallel with the functional circuit. A discharge member is provided in each electric circuit and arranged between each input terminal and the functional circuit. The discharge member includes a discharge gap which allows the discharge member to face with the discharge member of an adjacently arranged electric circuit.The discharge gap discharge deliberately to the adjacently positioned discharge member when a voltage applied to a selected electric circuit exceeds a predetermined voltage value.
