Title: Injection of resin to produce a moulding with a thick section on one side and a high quality surface finish
Inventor: YASUDA KAZUHARU
IPC: B29C45/17
Filed: 1997-10-06
Abstract: A process for injecting moulding a resin to produce a component with a thick section on one side and a higher quality surface finish uses a tool with two opposing plates (1a,1b) enclosing a moulding cavity (2) with first (2b) and second (2a) walls for forming the rear and front walls of a moulded product and the first wall having one or more recesses for forming cavities in the moulding. The cavity (2) is connected to a gas inlet (10) and a polymer injection inlet and a gas release passage (3) runs from an opening in an inner wall surface of the cavity to atmosphere along a land face between the tool halves. An excess amount of resin, compared to the cavity volume, is injected to fill the cavity (2) and form the rear and front faces of the moulding while forcing trapped gas out to atmosphere via the gas release passager (3). A compressed gas, inert to the resin, is then injected through the first cavity wall (2b) to create a closed chamber full of gas which presses against the rear f ace of the resin to force the latter against the second cavity wall (2a) to enhance surface finish.

Abstract: The device (TR) is located in a heated area of an electric heating (Q), comprising a sealed regulator casing (RG), housing a control processor (ST) with a nominal point generator (P), a temperature sensor (TH), and a power switching element (R). The control processor produces a real-time switch on/off ratio for the switching element in periodic intervals, dependent on a comparison of an actual temperature value and the nominal point, whereby it controls the heating. The device (TR) is located in a heated area of an electric heating (Q), comprising a regulator casing (RG) which is sealed against dust, and which houses a control processor (ST) with a nominal point generator (P), a temperature sensor (TH), and a power switching element (R) which controls the heating.  The control processor produces a real-time switch on/off ratio for the switching element in periodic intervals, dependent on a comparison of an actual temperature value and the nominal point, whereby it controls the heating. The comparison is respectively performed with the actual value measured at half the switch-off time period or with an average value of both actual values measured in the beginning and at the end of the switch-off time.

Filed: 1998-03-09
Abstract: A component (1) consists of an electrically conductive ceramic, in particular, a filter element, which is penetrable by a flow through its pores, and is provided with contact regions for attachment of electrodes. An electrically conductive metal is infiltrated into the contact regions (10, 11, 12, 13). An Independent claim is also included for a method for producing contact regions by infiltrating an electrically conductive metal into these contact regions. Preferred Features: The ceramic consists of a metal and ceramic compound, whose metal constituent is the same as the infiltrated metal. The ceramic of the contact layers is the same as the material of the main body of the component. The contact layers have finer bores than the main body of the component. The contact layers can be at least partially pressed into the main body of the component. Component consists of a main body (2) and a connector body (3) joined to one another. Both have the same ceramic as a basic material. The two bodies are joined by active soldering, high temperature soldering or diffusion welding. Alternatively they are joined by means of an electrically conductive connector layer. The metal infiltrated into the connector layer is partially also infiltrated into the main body of the component. For infiltration the metal is heated at least up to its melting point. Infiltration takes place in vacuum or under a protective gas. For infiltration a mixture is used in which the metal content is above the stoichiometric ratio, so that at the reaction temperature only a part of it is converted into an electrically conductive ceramic component. The connector bodies are attached to the ends of the main body (2) of the component.
