    摘要: 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.

    摘要: 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.

    摘要: A wafer dividing method for dividing a wafer having a film on the front side thereof. The wafer dividing method includes a modified layer forming step of applying a laser beam having a transmission wavelength to the substrate of the wafer from the front side thereof along the streets so that a focal point of the laser beam is set inside the substrate, thereby forming a modified layer in the substrate along each street, a film dividing step of applying a laser beam having an absorption wavelength to the film from the front side of the wafer along each street to thereby form a laser processed groove for dividing the film along each street, a back grinding step of grinding the back side of the substrate of the wafer to thereby reduce the thickness of the wafer to a predetermined thickness, a wafer supporting step of attaching the wafer to a dicing tape supported to an annular frame, and a wafer breaking step of applying an external force to the wafer by expanding the dicing tape to thereby break the wafer along each street.
