Abstract: The present invention is directed to a method for developing a bond having a shear strength in excess of 1200 psi (82.68 bars) between dental cements and dental appliances fashioned from glass-ceramic materials. The inventive method consists of contacting the fitting surface of the appliance with an etchant in flowable gel form at a temperature below about 150°F (65.56°C), while protecting the exterior surface of the appliance. Subsequently, a silane solution followed by a dental cement is applied to the etched surface and cured in place.

Abstract: There is disclosed a multi-processing arrangement in which processes running on one processor may utilize processes, called stub processes, running on other processors. One problem that occurs with respect to such a system is that signals, which indicate the occurrence of external asynchronous events, must be processed in a specified order if the system is to work properly. Disclosed is a system for insuring the proper processing of such signals by requiring all such signals to be routed from a receiving process on a adjunct processor to the main user process on the originating processor. Also disclosed is an arrangement for insuring that signals are not lost and that duplicate signals are not processed.

Abstract: In a video camera having an automatic iris function and a gamma correcting function, an object evaluating value is calculated based on an exposure evaluating value in a sampling area designated as a priority area, a target luminance level for exposure control is changed according to the relation between this object evaluating value and exposure evaluating values in sampling areas other than the sampling area selected as the priority area, a ratio with which the priority area is weighted in calculating the object evaluating value is changed, and a correction value for gamma correction is further changed. As a result, overexposure and underexposure in a picture are decreased. Furthermore, if an extremely small value is included in exposure evaluating values in sampling areas, the value is previously replaced with a predetermined fixed value, so that the effect of noises or the like on exposure adjustment is decreased.

Abstract: The silicone rubber adhesive film of the present invention is characterized by simplicity of handling and an excellent workability and useability, as well as by adhesiveness for various types of substrates and an excellent durability of adhesion. These characteristics are obtained because the silicone rubber adhesive film of the present invention comprises a silicone rubber composition which consists of components (A) through (G), particularly the specific wet-method hydrophobicized reinforcing silica comprising component (C) and the specific compounds of components (D) and (E) or components (D), (E), and (F), and because the tensile strength of said uncured silicone rubber composition falls within the range of 1.5 kg/cm² to 5.0 kg/cm² at 25 degrees Centigrade (JIS K 6301). Accordingly, when used on flat substrates such as textiles, glass, rubber sheet, etc., it can tightly bond the adherend partners into a single, integral body.

Abstract: In known machines of this type, it is necessary for exchanging the preparation device to dismantle the latter together with the drive, for which purpose a relatively large opening is required in the container wall and much time and effort is necessary. The new machine is intended to allow the preparation devices to be exchanged more quickly and with less effort. 
<??>In the new machine, the preparation devices are formed from two parts which can be separated from each other so that the part of the preparation devices bearing the comminution tools can be installed and also dismantled from the inside of the container of the machine while the other part is permanently fixed to the outside of the container. 
<??>For mounting the preparation devices, the machine requires only relatively small openings in the container wall which, if they are not required, can be closed in a simple manner by an insertable lid. Installation and dismantling of the comminution tools is fast and can be undertaken by a single person because only one screw has to be screwed in or unscrewed for this purpose.

IPC: C23C16/448
Filed: 1989-11-08
Abstract: A chemical vapor deposition (CVD) system (100) compares the mass flow rates of a gas stream before and after reactant is transported by a carrier gas to determine the mass flow rate of reactant into a reaction chamber (102). This determination is used to control the carrier mass flow rate, which in turn permits regulation of the reactant mass flow rate. The CVD system (100) includes the reaction chamber (102), a delivery section (104) which delivers the reactant gas to the chamber (102), a heat source (106) for providing heat to the reaction chamber (102) to facilitate deposition on a wafer (99), an effluent handling system (108), which evacuates spent reactant from the reactant chamber (102), and a controller (110) which coordinates these components. Carrier gas is transported to and through an ampule (134) containing a liquid source (136) for the reactant gas, which is mixed with the carrier gas to form a combined gas. 
     The delivery system (104) includes sensors (114, 116) to measure the mass flow rates of the carrier gas before entry into the ampule (134) and of the combined gas on route to the reaction chamber (102). The mass flow mesurements are used by the controller (110) to control a valve (118) to regulate the mass flow rate of carrier gas into the ampule (134) thus controlling the mass flow rate of reactant out of the ampule (134) and into the reaction chamber (102). The controller (110) also regulates the removal of spent gases from the reaction chamber (102) by the effluent handling system (108) so that constant pressure is maintained with the reaction chamber (102). This ensures the stability of the delivery system control loop defined above.
