20080290543 | Method for Injection Expansion Molding of Thermoplastic Resin - An injection-foaming method for a thermoplastic resin comprising using an injection unit | 11-27-2008 |
20090121375 | Method for multilayer molding of thermoplastic resins and multilayer molding apparatus - A multilayer-molding method includes the steps of mixing at least one thermoplastic resin selected from a plurality of types of thermoplastic resins with a bubble-nucleating agent and a foaming gas, injecting the plurality of types of thermoplastic resins into a mold cavity such that the thermoplastic resins are layered in the mold cavity, and then, after increasing the volume of the mold cavity, foaming the at least one thermoplastic resin mixed with the bubble-nucleating agent and the foaming gas. The multilayer-molding method is characterized in that the foaming gas is supplied at a pressure of 0.1 MPa or more but less than 1.0 MPa to at least one injection-molding machine selected from a plurality of injection-molding machines, and that the thermoplastic resin plasticized in the injection-molding machine is mixed with the foaming gas. | 05-14-2009 |
20090134541 | Method for Foam Injection Molding of Thermoplastic Resin - A method for injection foaming molding of a thermoplastic resin includes the steps of (1) injecting the foaming-agent-containing plasticized resin from an injection apparatus | 05-28-2009 |
20100308500 | Resin multiplayer injection molding method - While a second layer resin is being charged, a movable platen is moved backward to reach a given movable platen position (S | 12-09-2010 |

20150097360 | CURTAIN AIRBAG DEVICE - A curtain airbag device where an airbag main body provided along a roof side rail is deployed in the form of a curtain inside the vehicle compartment by operation of an inflator. The airbag main body includes a first expansion part disposed at a position overlying a center pillar and supplied with gas by operation of the inflator during deployment; a second expansion part disposed to the rear of the first expansion part and supplied with gas from the first expansion part; and a gas communication part providing communication between the first expansion part and the second expansion part. The gas communication part is provided above a seatbelt interference region where the deployed airbag main body interferes with the seatbelt. When the vehicle is subjected to an external impact and the airbag main body expands, gas flows from the first expansion part to the second expansion part. | 04-09-2015 |
