Abstract: A vertical type bipolar transistor has a base region on a semiconductor substrate (1, 2, 4) formed by a graft base region (11), an intrinsic base region (12) separated from the graft base region (11) and having an emitter region (14) within it, and a link impurity diffusion region (13) linking the graft and intrinsic base regions (11, 12). During production, the graft base region (11) is formed by diffusion of impurities from a base contact electrode layer (6) and the emitter region (14) formed in the intrinsic base region (12) may be formed in self-alignment. In the vicinity of the junction between the base region and the semiconductor substrate (1, 2, 4), there is formed a diffusion suppression region (15) composed of an impurity diffusion region of a conductivity type opposite to that of the base region; this prevents the depth of the junction from being increased.

Abstract: An automotive transmission control is shown having pressure switches to sense the state of actuation of solenoid valves to provide logic signals to a microprocessor type of transmission control. The pressure switches, which sense the pressure of hydraulic fluid controlled by the solenoid valves, use a dished shaped metallic diaphragm characterized in that the pressure-deflection curve of the center of the diaphragm has minimal hysteresis and reflects that the diaphragm is relatively stiff having a positive coefficient of pressure with increasing deflection up to and above a selected pressure level at which level the center accelerates between d₁ and d₂. The diaphragm is loosely held on a conductor at 0 psig with the fluid pressure when it increases forcing the diaphragm into sealing and electrical engagement with the conductor.

Abstract: A p-type tub in a CMOS integrated circuit is isolated from the adjacent n-type tub by means of a field oxide (65) having a p-type channel stop region (66) formed by a boron ion implant. The depth of the ion implant is selected so that the peak of the boron concentration is located immediately under the field oxide region that is subsequently grown. In addition, the implant is allowed to penetrate into the active device regions, producing a retrograde boron concentration in the n-channel region. This technique simultaneously improves device isolation and n-channel transistor punch-through characteristics, allowing the extension of CMOS technology to sub-micron device geometries.

Abstract: There is a growing demand for high molecular weight polyester resin. For instance, the market for high molecular weight polyethylene terephthalate resin is rapidly expanding. High molecular polyethylene terephthalate resin is currently being used in vast quantities in manufacturing bottles for carbonated beverages, trays for frozen foods which can be heated in either microwave ovens or convection ovens, and in tire cord. There is a growing trend toward higher molecular weights in many applications for such polyester resins. Unfortunately, it becomes progressively more difficult and expensive to produce polyester resins having higher and higher molecular weights utilizing standard commercial polymerization techniques. This application discloses a technique by which polyester resin having extremely high molecular weight can be prepared utilizing a very rapid solid state polymerization process. This application more specifically discloses a process for preparing ultra-high molecular weight polyester resin which comprises: (1) dissolving a polyester prepolymer in a suitable organic solvent: (2) recovering the polyester prepolymer from the organic solvent to produce a porous, fibrous mass of the polyester prepolymer; and (3) solid state polymerizing the porous, fibrous mass at an elevated temperature to produce the ultra-high molecular weight polyester resin.

Abstract: A lead of a lead frame cannot be made close to a very small semiconductor chip in view of processing dimensions. If a TAB technique is used to directly con­nect the semiconductor chip and the lead in order to improve in reliability, a device for forming a bump on an electrode of the chip is required, which increases the cost of investment in equipment. A printed circuit board (33) is formed between the lead (34) and bed (31) and a bonding wire (37) is used to shorten the length of wiring and thus to decrease in cost and improve in reliability. Since an electrode pad (35) of the semi­conductor chip (32), the printed circuit board (33), and the lead (34) are connected to each other using the TAB technique, the productivity of semiconductor devices is increased. Using the TAB technique, no bumps are formed anywhere and the cost of investment in equipment is not so increased.

Abstract: The system and method of this invention provides an access control list which spans across object boundaries in an object oriented database. In addition to providing read and write access permissions, the access control list provides execute semantics which apply to the execution of methods in an object oriented database. Within the entries of the access control lists, each of the permissions for read, write, and execute can be assigned separately to each of a number of ids representing user ids or group ids. Upon request for access to the data by the user, the user id of the user and the group ids for which the user is a member are searched for within the entries to determine whether the user has the privileges to perform the operation requested against the objects. In addition, the access control policies are inherited from an object's superobject; resulting in a least privilege for the object.

Abstract: A system and method is disclosed for enabling a plurality of computers and associated computer resources. some or all of which may be of heterogeneous configuration, to cooperatively process a variety of applications such that the execution is transparent to the user regardless of where the application is actually executing. This distributed applications architecture performs an information distribution service between multiple transaction processing systems by working with a transaction processor via communication channels to other hosts within the network and a dialog manager (26) which uses a transaction processor interface (78) to communicate with the transaction processor. Additionally, the architecture employs a map service (36,40) to provide an editor to allow application programmers to create the maps (40) for the application panels, a compiler to generate the maps into linkable form, and a linkable interpreter which translates the linkable form into the screen presentation format for that platform. Furthermore, to distribute an application, the source code for the procedures (32), views (38) and panels are moved as a block to the new system. This is possible because once the application source code is complete, all of the application logic, user interface control tables, view definitions, and other application-specific tables for one transaction definition are packaged by the present invention in a single load module on the system where the application will reside. The load module is then compiled using the target system's compiler, link editor, and bind process. Thus, all environment-dependent vanations of import/export, including network protocol, operating systems, processor types, etc., are automatically integrated with the application at load module bind time. Therefore, no source code changes are necessary.
