Filed: 1990-12-05
Abstract: A process for making a component by (A) depositing a first layer of a powder material in a confined region and then (B) depositing a binder material to selected regions of the layer of powder material to produce a layer of bonded powder material at the selected regions. Such steps are repeated a selected number of times to produce successive layers of selected regions of bonded powder material (C) so as to form the desired component (D). The unbonded powder material is then removed (E). In some cases the component may be further processed as, for example, by heating it to further strengthen the bonding thereof.

Abstract: Image defining toner is transferred to cut sheets and fused at one of two fuser stations (21,22). One station (22) is positioned to fuse the image on one side when duplex copying or printing is selected. The other fuser station (21) performs fusing when simplex copying is selected but fuses the second side copy for duplexing. When flash lamps are employed for the fuser station, the lamps are composed of multiple bays with a single power source coupled to each bay in sequence so that the power source size need only accommodate the power level demand of one bay. The time between trigger pulses is extended by commencing fusing with an intermediate bay followed by the initial bay and then the final bay as the image area requiring fusing passes along its path in proximity to the faces of the flash lamp bays.

Title: Tape cassette loading mechanism
Inventor: OHSHIMA MINEO
IPC: G11B23/087
Filed: 1991-02-26
Abstract: A cassette loading mechanism operable with any one of first and second cassettes each accommodating therein a reeled magnetic recording tape. The first cassette is of a type having a uniform thickness and a head access window and at least one roller access window defined at a front thereof and also has a normally closed slide shutter for selectively opening and closing both of the head and roller access windows. The second cassette has a head access window and at least one roller access window defined at a bulged region at a front thereof and has therefore maximum and minimum thicknesses. The cassette loading mechanism comprises spaced apart holders for holding any one of the first and second cassettes, a detecting lever assembly movable in a plane parallel to a cassette inserting plane between first and second positions and also for movement in a direction generally diverging from the cassette inserting plane. The assembly normally biased to the first position by a biasing element is moved towards the second position in response to the insertion of only the first tape cassette. The assembly includes an actuating element for moving the slide shutter towards the opened position as the lever assembly is moved towards the second position. The lever assembly is also moved in a direction away from the cassette inserting plane in the event that the second tape cassette is inserted to allow the bulged region of the second tape cassette to pass clear of the actuating element.

Filed: 1991-03-14
Abstract: A bit-serial division method is disclosed for computing the value v/u, where v and u represent vectors in a canonical basis constituting elements in a finite field consisting of 2 n  elements. Vector u is converted from canonical basis to a dual basis, and each basis comprises n elements in the finite field ordered according to an index i that takes on values from 0 to (n-1). All bits n of the converted vector u are loaded into a shift register in parallel, then converted from dual basis back to canonical basis to produce a single bit output w₀ from a lookup table which generates bitwise the inverse of the n-bit vector u. The bits in the shift register are shifted (n-1) times to generate successive additional single bit outputs w i  with said lookup table. Then each bit w i  is multiplied by the vector v and a corresponding element c i  in dual basis to generate a cumulative sum of these products that provides, upon completion of said number of shifts, the bit-serial division result v/u.

Abstract: Tracks scanned by a playback head (H) have a first signal (f₁) recorded in every nth track (T), a second signal (f₂) recorded in a track (T) which precedes and is adjacent to each nth track (T) and a third signal (f₃) recorded in a track which follows and is adjacent to each nth track (T). When a preceding track (T) is scanned, the second signal (f₂) recorded therein is detected; and at a time delayed from the detection of that second signal (f₂), the first signal (f₁) picked up as a cross-talk component is sensed. When a following track (T) is scanned, the third signal (f₃) recorded therein is detected; and at a time delayed from the detection of the third signal (f₃), the first signal (f₁) picked up as a cross-talk component is sensed. The difference between the first signal (f₁) sensed when a preceding track (T) is scanned and the first signal (f₁) sensed when a following track (T) is scanned is indicative of a tracking error.

Abstract: A call processing method for distributed switching substantially increases the percentage of calls that are intra-module calls by distributing the members of trunk groups (TG1, TG2) among a plurality of switching modules (13000-1... 13000-4) and biasing the processing of a call originating on one switching module such that an available trunk group member on that same switching module is assigned to the call if possible. The path hunt function for intra-module calls is separated from the corresponding function for inter-module calls and only the latter function is performed by the system central control (14000). The separation is achieved by dividing the set of switch path resources, e.g., channels or time slots, associated with a switching module into two disjoint subsets--a first subset for intramodule call connections and a second subset for inter-module call connections.

Abstract: A burner assembly (10) for process heaters or the like comprising a burner block (14), primary gas jets (20), secondary gas jets (22), a flame holder (26), and an air register for installation in a furnace wall or furnace floor is described. The burners are characterized in that primary fuel is introduced into the primary combustion zone (24) of the burner at an angle horizontal to the flame holder whereby the fuel induces furnace gases from the furnace into the primary combustion zone. Similarly, the secondary fuel jets introduce a secondary fuel through the burner block for consumption in a combustion zone at the surface of the burner block. The secondary fuel also draws furnace gases into the combustion zone for consumption. The design provides for intense mixing of combustion air with the fuel and furnace gases, resulting in low NOx levels.

Abstract: A generalized analysis-by-synthesis method and apparatus are disclosed. A plurality of trial original signals are generated based on an original signal for coding. The trial original signals are constrained to be perceptually similar to the original signal. Trial original signals are coded to produce one or more parameters representative thereof. Estimates of the trial original signals are synthesized from these parameters. Errors between the trial original signals and the synthesized estimates are determined. A coded representation of the original signal is determined which comprises parameters of the trial original signal having an associated error which satisfies an error evaluation process. Trial original signals may be generated by application of time-warps or time-shifts to the original signal. Coding of a trial original signal may be performed with conventional analysis-by-synthesis coding such as code-excited linear prediction coding (CELP). A minimum square error process may serve as the error criterion.

Abstract: The invention relates to the production of a pressure glass passing-through in a metal body. Such pressure glass passing-throughs are used in metal housings for semiconductors, in particular integrated circuits. These passing-throughs must hermetically seal the interior of the housing from the exterior. For this purpose, a glass bead is fused into a bore of the housing and the connecting lead of the integrated circuit is passed through the glass to the outside. It has now been found that alloys of the Cu, Al, Mg systems show, during cooling after the fusion step, a hardening effect with the result that, with these alloys, pressure glass passing-throughs can be produced which show hermetic sealing even after high thermal and/or mechanical stress. They have a high thermal shock resistance and good corrosion resistance. <IMAGE>
