Title: Polyvinyl chloride resin composition for powder molding
Inventor: KOBAYASHI MASANORI
IPC: C08K3/16
Filed: 1987-05-15
Granted: 1992-04-21
Abstract: ABSTRACT     This invention relates to a polyvinyl chloride resin composition for use in powder moulding.  The prior art polyvinyl chloride resin compositions are known to stain the surface of moulds during use.  This staining necessitates frequent stoppages in order to clean the mould and hence productivity decreases whilst costs increase.  In this invention, a fatty acid soap having an alkyl chain of 5 to 8 carbon atoms and a zinc or barium metal ion is used as a stabilizer in the resin composition.  The stabilizer reduces staining of the surface of a mould in use.

Granted: 1992-04-28
Abstract: ABSTRACT OF THE DISCLOSURE A self-cleaning type cooking oven with a cooking chamber which has a function to pyrolytically eliminate food soils accumulated on walls of the cooking chamber.  The cooking oven includes a heater for supplying heat into the cooking chamber so as to allow to pyrolytically degrade the food soils and an exhausting passage coupled to the cooking chamber to exhaust gases generated due to the pyrolytical degradation to an ambient atmosphere.  In the exhausting passage is provided an oxidizing catalyst which oxidizes the gases introduced thereinto for exhausting and also provided a gas sensor to detect a gas component therearound.  Also included in the cooking oven is a heat control unit electrically connected to the heater for controlling heat supply into the cooking chamber, the heat control unit being responsive to a gas signal therefrom to determine a heating time period for chamber cleaning.  With the temperature of the cooking chamber being kept at a predetermined cleaning temperature, the heat control unit samples the gas signal at a given time interval to detect a variation of amount of the gas component and detect an inflection point from decreasing to increasing or vice versa in the gas-component variation to determine the heating time period in conjunction with the inflection point, the food soils being substantially degraded by heating during the heating time period.

Abstract: TITLE: COLOUR CHANGE DEVICES INCORPORATING THIN ANODIC FILMS A laminated colour change device which exhibits an irreversible colour change upon delamination. The device comprises two layers capable of generating a colour by a light interference and absorption phenomenon that requires direct and intimate contact between the two layers. One of the layers is a colour-generating metal, such as a valve metal (e.g. tantalum), and the other is an overlying lighttransmitting film thin enough to cause light interference effects The film is produced by coating the colour generating metal with aluminum or an aluminum alloy and then anodizing (preferably porous anodizing) the aluminum to consumption in the presence of an adhesion-reducing agent, e.g. fluoride, that reduces the strength of attachment between the layers so that the laminate can be uniformly and reliably separated at the interface between the adjacent two layers. An overlying layer of transparent or translucent material is normally adhered to the laminate to facilitate the separation of the layers. when the thin film is detached from the colour-generating metal, the generated colour is lost, thus providing a colour change that is in effect irreversible. The device can be incorporated into a variety of closable articles or products to provide evidence of opening or tampering, or can be used for other purposes.
