Title: Device and method for runner-less molding of thermosetting resin and rubber
Inventor: TANAKA YOSHIAKI
IPC: B29C45/27
Filed: 2002-10-01
Granted: 2009-05-26
Abstract: A runner-less molding device for thermosetting resins and rubbers, characterized by a movable runner bush (15), through which an uncured or unvulcanized fluid material kept at a low temperature supplied from a pouring nozzle (31) can flow, is slidably arranged in a temperature controlling bush (13) communicating with a gate (4) of a cavity (1); an insulation space (A) is formed by moving the movable runner bush (15) apart from the gate (4) during heating; a valve pin (18) is movably inserted into said movable runner bush (15); and the valve pin (18) is arranged so as to open and close the gate (4) in accordance with a pouring operation of the fluid material. A runner part of the movable runner bush containing molding material is constituted so as to move forward/backward relative to the cavity for preventing heat from conducting from the cavity, which is kept at a molding temperature, to the runner positioned apart from the gate for a long time, so that material loss generated in a sprue runner is reduced to almost null in order to reduce fabricating costs after molding and amount of wastes generated during after treatments. Thus, the improved molding device for the thermosetting resin and the rubber is obtained, and burdens on the global environment are alleviated.

Abstract: A method for removing the air wave effect from offshore frequency domain controlled source electromagnetic survey data. The region of interest is modeled with (111) and without (113) a top air layer. The electromagnetic field due to the source is computed at the survey receiver positions for each source position for both models. The difference between the fields computed (116) from the two models is the air wave effect, which is then subtracted (117) from the field data for the corresponding source-receiver geometry.
