Abstract: A system for providing input to a computer comprises a touchscreen apparatus for generating a grid of horizontal and vertical light beams and producing a set of output signals, each indicating whether a corresponding one of the light beams strikes an object. A scanning device repeatedly scans the states of the output signals, stores data representing the last scanned state of each output signal, and transmits a first interrupt signal to the computer whenever the state of any one of the output signals changes. In response to the inter­rupt signal, the computer reads the stored scan data, determines whether the data indicates that a horizontal and a vertical light beam is striking an object, and if so, sets parameter values to iden­tify the horizontal and vertical light beams. In response to a second interrupt signal periodically generated by a clock, the computer determines whether or not the parameter values have remained constant for a predetermined period, and if so executes a routine responsive to the parameter values.

Abstract: In the fabrication of bipolar transistors by the single poly process, polysilicon sidewalls are formed along portions of a polysilicon layer that functions as a device contact. The sidewalls serve both as dopant sources which determine the width of underlying base and emitter regions, and as contacts to these devices. Since the thickness of the polysilicon sidewalls, and hence the width of the underlying device regions, are precisely controllable through conventional polysilicon deposition techniques, relatively relaxed design rules can be employed while making possible the formation of emitters having widths less than one-half of a micron.

Abstract: An explosive powder charge operated tool for driving nails includes a housing with a muzzle part mounted in and projecting axially outwardly from the housing. By moving the muzzle part rearwardly into the housing, the tool is in the ready-to-fire condition. A magazine is supported at one end within the muzzle part and extends generally radially outwardly from it. A slide in the magazine feeds individual nails in a nail strip into the bore in muzzle part into position to be driven by a piston located within the housing. When all of the nails in the strip have been driven from the tool, one end of the strip projects into the muzzle bore. A stop shoulder on the one end of the strip faces toward an end face on the housing and contacts the end face when the muzzle part is pressed into the housing, preventing the placement of the tool in the ready-to-fire condition.

Abstract: This invention relates to a method of enhancing linear impressions formed in the surface of grain oriented electrical steel strip, by electrolytically etching said impressions with e.g. citric acid. The impressions may be formed by mechanical wheel scribing or by surface ablation, e.g. by spark discharge or laser treatment, and may be continuous or discontinuous in the form of spots or lines. In accordance with this invention therefore, the initial generation of light impressions in steel strip formed by mechanical wheel scribing or spark ablation techniques can readily be enhanced by application of the electrolytic etching technique to produce a material exhibiting values of power loss (reduced from the original unscribed loss value) which are substantially anneal-proof. In comparison, conventionally scribed material shows no resistance to a high temperature anneal as far as loss reduction is concerned.

Abstract: An object based data processing system including an extensible set of object types and a corresponding set of "object managers" (196) wherein each object manager is a program for operating with the data stored in a corresponding type of object. The object managers in general support at least a standard set of operations. Any program can effect performance of these standard operations on objects of any type by making an "invocation" request. In response to an invocation request, object management services (194, 218) (which are available to all object managers) identifies and invokes an object manager that is suitable for performing the requested operation on the specified type of data. A mechanism is provided for linking data from one object into another object. An object catalog (252) includes both information about objects and about links between objects. Data interchange services (812) are provided for communicating data between objects of different types, using a set of standard data interchange formats. A matchmaker facility (810) permits two processes that are to cooperate in a data interchange operation identify each other and to identify data formats they have in common. A facility (222) is provided for matching shared data   "resources". Customized versions of resources can be created and co-exist with standard resources. A resource retrieval function determines whether a customized or a standard resource is to be returned in response to each request for a resource.

Abstract: A power transition circuit (2) protects a bipolar-­CMOS (BiCMOS) circuit during power transitions. Reference signals (Vref+, Vref) proportional to the voltage supplied to the protected circuit (Vcc, Vee) are monitored, and the power transition circuit (2) determines from the voltage differen­tial between the reference signals (Vref+, Vref) whether a power transition is occurring. If a transition is present, the transition circuit (2) disables the protected BiCMOS circuit for as long as the power transition exists. An independent input signal (Vcsm) allows the power transition circuit (2) to disable the protected BiCMOS circuit in response to other conditions.

Abstract: A simulation engine for logically simulating a logic network, which is divided into several levels of hierarchy. At the lowest level is a logic chip which has stored in an instruction memory a sequentially executed program of logical operators and operand addresses. The operand addresses refer to an input memory of the chip. The next highest level is the logic unit, on one circuit board, comprising a plurality of such logic chips. Each of the logic chips of the unit has its input memory receiving the same data from an input bus and a local bus and provides as its output one of the bits of an output bus and one of the bits of the local bus. At the next level, called a cluster, several logic units have their input and output buses interconnected by a plurality of switch units. All the logic chips of the several logic units operate in parallel with the exchange of data through the switch units. Several clusters can be combined into a super cluster by connecting together two or more sets of switch units.

Abstract: In a method of controlling speed range shifting, an input-output speed ratio (= output speed/input speed) in a shifting means by which a power transmitting route for the pre-shift speed range is selected is detected when a shift signal to shift from a speed range in which engine brake is available to another speed range in which engine brake is also available is transmitted. An intermediate power transmitting route in which engine brake is not available is selected after the transmission of a shift signal as long as the change of the speed ratio is within a specified range. Then, a power transmitting route for the post-shift speed range is selected based on the shift signal when the change in the speed ratio becomes bigger than the specified range.
