Title: Image-forming method, and ink ribbon and a printing sheet used for the method
Inventor: ITO KENGO
IPC: B41M5/39
Filed: 1992-03-16
Abstract: A method for forming images by a thermal transfer process.      The method comprises the steps of providing a printing sheet having an image-receiving layer on one side thereof, providing an ink ribbon having a dye layer comprising a hydrophilic cationic dye, contacting the ink ribbon with the image-receiving layer, and applying a thermal energy to the ink ribbon in an imagewise pattern to thermally transfer the dye from the ink ribbon to the image-receiving layer. The image-receiving layer comprises at least a layer compound which has ion exchangeability with the cationic dye, so that the dye image is fixed through the ion exchange. Since the dye is bonded to the layer compound through ion exchange, the dye is fixed comparable to that of silver salt photography. A thermal transfer system using the ink ribbon and the printing sheet is also described.

Abstract: ABSTRACT OF THE DISCLOSURE A plastic vessel (10) for containing a hot liquid and having the capability of being placed on a hot plate, burner or the like to maintain the liquid hot includes a top portion (11) molded of a first heat resistant plastic material.  A base portion (13) molded of a second plastic material being more heat resistant than the first plastic material is attached to the top portion (11) to close the same and form the container for the hot liquid.  One form of attachment of the base portion (13) to the top portion (11) is the utilization of a gasket (12) preferably formulated of a mixture of the first and second plastic materials which is heated to fuse the top portion (11) to the base portion (13).  A heat shield (14, 40), formed of a third plastic material which is more heat resistant than the first and second plastic materials and which can withstand the heat of direct contact with the hot plate, is attached to the bottom of the base portion (13).  One form of such attachment is a heat stake (32) which depends from the bottom of the base portion (13) and extends through an aperture (33) in the heat shield (14, 40) for attachment by a staking process.

IPC: F16K15/06
Filed: 1992-05-19
Abstract: ABSTRACT    A check valve assembly is disclosed wherein a valve closure means includes a guide means and a connector means as a composite member for use in a pipeline or conduit inclined to the vertical.  The mass of the composite member relative to the angle of inclination and the coefficient of friction between the internal surface of the valve body and the external surface of the guide means is such that there is no risk of valve "jamming" action which would block operation of the valve.  In addition the guide means ensures symmetrical fluid flow whereby the valve operates positively and rapidly eliminating chatter and erratic travel during the course of opening and closing when fluid flow is reversed.
