  • Publication number: 20160121527
    Abstract: In order to produce a plastic container (1,2) having a planar electronic element (15), a planar electronic element (15) is introduced into a recess (29) of an inner face of a mold. The mold comprises an outer mold part (10) and a mold core (11), which form a mold cavity (12). Molten plastic material is injected into the mold cavity (12). After the subsequent cooling of the plastic material, mold removal is carried out. The recess (29) is arranged on an inner face (26) of the outer mold part (10). The molten plastic material is injected into the mold cavity in such a way that the molten plastic material flows substantially parallel along a surface (25) of the planar electronic element (15) facing the mold cavity (12). The planar electronic element (15) is an RFID inlay, for example. The planar electronic element does not require a protective casing and can be sprayed directly.

  • Publication number: 20120237725
    Abstract: Before back molding, the planar decorative element is provided with through-holes. At least in the area of the through-holes, a film is applied to the rear of the planar decorative element. When a plastic melt is introduced, for example by way of injection molding or extruding, the pressure of the plastic melt presses the film into the through-holes. The component is used, in particular, to produce an illuminable field, for example, of a door sill protector of a motor vehicle.

  • Publication number: 20090254298
    Abstract: In order to determine at least one surface temperature of an outside of a cooling body (2) at a time xn, at least one temperature measuring device (3) is used to measure the temperature at least one surface point of the outside of the body (2) at at least two different times after the production or processing method which was used to produce or process the body (2) has been concluded. On the basis of the temperatures measured, a temperature/time function (17) is calculated using regression analysis. The surface temperature at the time xn, which is before the at least two different times, is determined using the temperature/time function (17). The temperature at the time xn is used to optimize the production or processing method from which the body (2) results.

  • Publication number: 20080022755
    Abstract: The invention provides a gas detection method and a gas sensor which utilize an amount of change in the electrical characteristic of a gas sensitive thin film with respect to the adsorption amount of a gas to be detected. The gas sensitive thin film (7) having characteristic detection electrodes (5, 6) functioning as a sandwich electrode or a gap electrode is laid out on a crystal resonator (10), and change in the electrical characteristic of the gas sensitive thin film (7) with respect to the adsorption amount of the detection target gas is observed by simultaneously determining change in the oscillatory frequency of the crystal resonator (10) and the electrical characteristic of the gas sensitive thin film (7). Because the sensor is an integral type device, both changes in an adsorption mass and the electrical characteristic can be surely monitored.
