Abstract: METHOD OF PREPARING A DIELECTRIC-ISOLATED          SUBSTRATE FOR SEMICONDUCTOR INTEGRATED CIRCUITRIES            ABSTRACT OF THE DISCLOSURE  In the preparation of a dielectric-isolated substrate for semiconductor integrated circuitries which comprises a plurality of silicon single crystalline islands in which circuit elements are formed, a region made of an alternate laminate of silicon polycrystalline layers and silicon oxide films for supporting the plura-lity of silicon single crystalline islands, and a silicon oxide film interposed between the silicon single crystal-line islands and the support region for isolating each of the silicon single crystalline islands from the remain-ing ones and the support region, the formation of three to twelve silicon polycrystalline layers in the support region can remarkably reduce the bending of the substrate resulting from the growth stress of the silicon polycrystal-line layers or from the difference in thermal expansion coefficients between the single crystalline silicon and the polycrystalline silicon, and therefore produces a dielectric-isolated substrate showing little bending.

Abstract: ABSTRACT OF THE DISCLOSURE        A hermetically- sealed vaporization chamber contains heat-producing electrical apparatus such as a transformer to be cooled while dielectrically protected, and also contains a two-phase dielectric fluid (a liquid and a vapor).  The liquid resides at a bottom portion of the chamber, and is further distributed of vertical cooling ducts which extend through the apparatus.  The vapor is produced by vaporization of the liquid by heat from the apparatus, the vapor occupying space in the chamber above the liquid level.  A condenser has one end connected in communication with an upper portion of the vaporization chamber occupied by the vapor.  A reservoir containing a predetermined mass of non-condensible dielectric gas is above the condenser, and the condenser has another end connected in communication with the reservoir and the gas within it.  A liquid dam is positioned on the upper edges of the apparatus adjacent the vertical ducts.  A distribution pan in the chamber is located above the liquid dam for receiving liquid condensate from the condenser and distributing the liquid condensate from the condenser and distributing the liquid condensate uniformly to the liquid dam.  The liquid dam distributes the liquid condensate uniformly as a film over the wall surfaces of the adjacent vertical ducts.  A condensate make-pump is included for pumping liquid from the bottom portion of the chamber to the distribution pan.

Abstract: Abstract Pressure vessels for holding liquefied gases under pressure are provided with an interior wall covering of expanded highly heat-conductive mesh and a heat penetration-reducing exterior coating comprising an insulative, intumescent or ablative material.  On accidental exposure of the vessel to a fire hazard, the interior covering and coating serve to disperse and dissipate heat that is absorbed by vessel and its contents and delays the penetration of heat into the vessel from the exterior, so that weakening of the vessel wall to the point where it may rupture under the internally-generated pressure is prevented or delayed.

Abstract: OVEN HAVING A DILUTING VENTILATION SYSTEM        ABSTRACT         The specification discloses a self-cleaning oven including an outer housing with an oven liner disposed within the housing in a spaced-apart relationship forming cavities between the housing and liner walls.  A duct system is provided for directing air from the vicinity of the lower front and rear of the oven to the cavity between the top walls of the housing and liner.     A heating element is mounted in a proximate relationship to a smoke eliminator panel mounted on the top liner wall.  Smoke and gases emanating from the oven pass through apertures formed in the smoke eliminator panel to a vent tube.  The vent tube discharges gases from the smoke eliminator panel into a discharge duct above the oven liner.  A diluter tube encompassing the vent tube allows air to pass from the cavity between the top walls of the oven liner and the housing into the discharge duct.  The air dilutes the smoke and gases from the oven liner, and the diluted smoke and gases are then exhausted from apertures in the front of the oven.  In this arrangement, air flow results from thermal currents, and a fan is not required.
