Abstract: A data processing system is described which includes a circuit for storing a plurality of instructions in a sequence together with a circuit for fetching a plurality of instructions. A circuit is provided for dispatching a plurality of the instructions to one or more proces­sors for execution during a single computation cycle. A control circuit is connected to the dispatching circuit to delay the dispatching of an instruction, when the instruction has an execution result that is dependent upon a previous instruction execution that will set at least one bit in a condition register. The delayed instruction is delayed until that condition register has been accordingly set. Similarly, an instruction is delayed if that instruction will set a bit in the condition register which is still being accessed by a previous instruction.

Abstract: A finely divided metal-containing compound can be efficiently prepared by irradiating a mixed vapor phase of an organometallic compound in a concentration to exceed a specified lower limit and a reactant gaseous compound with laser beams having an incident energy density to exceed a specified lower limit. When the reactant gaseous compound in the vapor phase is an oxygen-containing compound, e.g., air, the resultant powdery product is an oxide of the metallic element of the organometallic compound. When the reactant gaseous compound in the vapor phase is a halogen-­containing compound, e.g., methyl halides, the resultant powdery product is a halide of the metallic element of the organometallic compound. When the reactant gaseous compound is a second organometallic compound, of which the metallic element is not the same as the metallic element in the first organometallic compound, the resultant powdery product is a composite metallic powder of which the distribution of the two metallic elements is uniform throughout each particle.

Abstract: The invention is intended to form a recess large in the opening width at the contact hole forming position of the insulator film before opening contact holes in the insulator film, and to open contact holes smaller in opening width at the bottom of the recess. 
     According to the manufacturing method of the inven­tion, since the opening size of the recess in the upper portion of the contact hole may be set larger, and by decreasing the shadowing effect when covering the aluminum alloy wiring layer, the degree of covering of the aluminum alloy wiring layer on the side wall of the contact hole is improved, as that reduction of contact resistance and enhancement of reliability may be achieved. Besides, since the bottom of the contact hole may be opened at high precision, mutual fine connection of wiring layers is possible, and even if the elements are integrated at high density, a proper clearance may be maintained between the contact hole and gate elec­trode, and thereby electrical leak between wiring layers may be effectively prevented.

Abstract: A process for the sequential purification and fractionation of air in a single column and in the absence of pretreating the air feed to remove moisture comprises passing an air feed containing a gaseous component harmful to humans through an adsorber column (13,25) to produce product effluent. The column has at least two adsorption zones (14,26;15,27). The first zone (14,26) comprises a feed purification adsorber for purifying an air feed and having a first adsorbent therein for adsorbing the harmful gaseous component and water vapor from said feed to effect purification. The first adsorbent is capable of being regenerated. The second zone (15,27) comprises an air fractionation adsorber for adsorbing at least one component of air and having a second adsorbent therein to effect fractionation of air. The second adsorbent is capable of being regenerated. The first zone operates as a heaterless   pressure-swing adsorber and said second zone operates as a purge sweep adsorber. The column (13,25) is sized so that the heat of adsorption released during the adsorption of water vapor from the air feed is retained in said column and so that on application of a volume of purge gas to said column said first and second adsorbents are both regenerated. The second zone (15,27) is sized so as to contain sufficient adsorbent to carry out the fractionation unaffected by the heat front generated by the heat of adsorption released in the first zone and to prevent breakthrough of the mass transfer front during fractionation. The product effluent is removed from said column.

Abstract: An actuator (1-21) for the throttle (2) of an internal combustion engine comprises a torque motor (3) and a return spring (19). The spring (19) provides a monotonically increasing return force for increasing throttle opening. The motor (2) has a torque characteristic such that, for constant motor current, the torque decreases monotonically for increasing throttle opening. The actuator (1-21) thus has a single-valued function of throttle position versus motor current and allows open loop control as well as stable closed loop control.

Abstract: A series resonant inverter (12) is controlled to provide a substantially constant output voltage to a load. The control utilizes a combination of optimal control methods and phase modulation to enable time optimal responses to changes in state of the system. State determinants (including resonant capacitor voltage, resonant inductor current, source voltage, and output load voltage) are continuously monitored, and an optimal control signal is generated therefrom. When operating within the operable frequency range of the inverter's controllable switch means, frequency is varied to maintain proper operation. When operating at an extremity of the operable frequency range, phase modulation is employed.

Abstract: A novel fabrication method is disclosed for fabricating a bipolar transistor having a digitated emitter electrode (105) and a contiguous polysilicon region (111) acting as a self-aligned base contact. The process substantially reduces the parasitic capacitances as well as eliminates the need for the intrinsic base region to be exposed to multiple etching, which results in the fabrication of small and reproducible base widths. 
     A first polysilicon layer is deposited over the surface of a semiconductor substrate and, then, implanted with base dopants, which are driven into the surface of the active region by a furnace process for forming an intrinsic base region (116). Emitter dopants are next implanted into the first polysilicon layer. Subsequently, a nitride layer is deposited and the digitated emitter fingers patterned by selective etching. Link-up regions for connecting the intrinsic base region and the extrinsic base regions to be formed later is formed by implanting portions of the substrate free of the emitter fingers with base dopants. Next, oxide sidewalls (109) are formed on the edges of the emitter fingers by depositing a conformal oxide layer and anisotropically etching the oxide layer, leaving vertical portions thereof on the edges of each emitter finger. Finally, a second polysilicon layer is deposited conformally over the entire structure and anisotropically etched back in order to form a planar, contiguous region (111) between each finger of the digitated electrode. Implanting the entire structure with base dopants forms the extrinsic base regions (115) outside the fingers of the digitated electrode. Heating the substrate to cause base dopants from the first polysilicon layer to diffuse into the substrate creates emitter regions (114) under the fingers of the digitated electrode.

Abstract: The invention relates to a method and a system for deskewing data transmitted via a dispersive medium such as a fiber optic link, wherein the relative delays in arrival time for a plurality of bits, propagated in separate channels are measured. The relative delays are used to calculate the wavelength (λ) of one channel and the zero dispersion wavelength (λ₀) of the medium. The relative delays in arrival tides for the remaining bits in a group of bits are predicted using the measured relative delays, the spacing (δ) between the transmitters and the calculated wavelengths. An adjustable delay for storing data bits is provided in each channel. The relative delays are used to deskew the individual bits.

Abstract: In a disk type mass storage facility for data processing systems, a disk format which improves handling of defective segments of medium and reduces access time. The format has three layers. A first, physical layer comprises the bytes, sectors and collections of sectors, as well as error detection and correction codes. A second, logical layer is used to address the physical layer and to collect together sectors to form multiplicity of separately addressable spaces, with space having a distinct functional utility. As a third, functional layer the use of data fields in each space is specified. This layer governs the handling of bad blocks if required, and the use of certain format information. At the physical layer, bits are collected into sectors, sectors are collected into tracks, tracks are collected into groups, and groups are collected into cylinders. These are logically, rather than physically, defined collections. A group is set of tracks wherein individual tracks in a group can be selected in the inter-sector rotation time. At the logical layer, the disk is divided into three main areas, each separately addressable. The first main area is broken down into two sub-areas. The first sub-area (12) is available to the host computing system for its use; the second sub-area (14 and 16) is used for replacement of the bad blocks. The second is for format information. The third main area (18) is for diagnostics. Handling of bad blocks is controlled by a hierarchically layered process. A portion of each disk, distributed across the medium, is reserved as spare sectors to replace defective sectors. After a bad sector is replaced, future attempts to access the bad sector are redirected (i.e., revectored) to the replacement sector. For the simplest revectoring, the bad block is replaced by a replacement block in a known location. If that cannot be done, multiple copies of the replacement block's header are stored in the bad block's data field and the copies are compared to find the replacement address. If the comparison fails, or the header cannot be read, a back-up table is available to match the available replacement addresses with the original address which was replaced. A special code is used to identify blocks wherein the medium is good but the contents of the block are logically corrupted.

Abstract: A rotary member (2) is continually held suspended in the space by a strong pinning force (fishing effect) of high temperature oxide superconductors (1) under superconductive state. The magnetic field of the magnets (3) on thus suspended rotary member (2) is distributed concentrically about the center of the pinning force, so that the rotary member can be continually rotated in a non-contact state while being lifted off the high temperature oxide superconductors (1). 
     Thus, by utilizing the external energy via an input/output device (10,11), the theory member (2) is rotated in a vacuum tank (6) under highly vacuum state and is held continually rotating for an extended period of time. 
     By taking out the kinetic energy of rotary member via the input/output device, the stored energy can be taken outside.
