Patent EP-0416809-A2 (EP)
Inventor: HILLS GRAHAM WILLIAM
IPC: H01L21/28
Filed: 1990-08-30
Abstract: A method of semiconductor fabrication which permits the creation of openings which have dimensions smaller than what may be achieved by conventional lithography. In an illustrative processing sequence, a pattern transfer material is deposited upon another material layer. The pattern transfer material is covered with photoresist which is subsequently patterned. With the patterned photoresist as a mask, the pattern transfer material is etched with a process which creates inward sloping walls. Then the pattern transfer material is used as a mask to etch the underlying material. The inward sloping walls of the pattern transfer material permit creation of an opening in the underlying material which is smaller than the corresponding opening in the photoresist. The method may also be used to create trenches or field oxides which have dimensions smaller than those achievable by lithography.

Abstract: A new structure, called a recursive run array, stores data as storage nodes linked in a tree structure, each storage node being adapted to store codes describing a run of data. A run of data is one or more consecutive, equal data elements. The codes describing a run of data include a count of the number of data elements within the run, and the data for the data elements of the run. The storage node can also store a starting index for the data elements of the run. Storage nodes can be linked in a tree structure by a first link to the first data element of a preceding run, and a second link to the first data element of a following run. A method in accordance with this invention includes identifying runs within the data; and for each run, storing codes describing the run in a storage node; and linking the storage nodes in a tree structure. The storage of data in a tree structure of storage nodes, with the contents of each storage node describing a run of the data, allows the data to be efficiently stored, searched, modified, and expanded.

Abstract: Measuring arrangement for the measurement and calculation of forces and torques in joints (2) of rotating torque-loaded universal-joint shafts (4, 6) and during angular movements of the universal-joint shafts relative to one another. For this purpose, one universal-joint shaft is subdivided into a first section (4a) as measuring shaft and a second section (4b) which are axially connected to one another via a coupling (20) which connects these two shaft parts in such a way that they are rotationally rigid and radially rigid but can move in an angular manner and can move axially relative to one another. The first section (4a) serving as measuring shaft can thereby perform pivoting movements about a pivot point (24) formed by the coupling (20) so far as clearance spaces in the joint (2) permit such movements. These movements are sufficient to measure radial and axial pressures of the measuring shaft (4a). With due allowance for the lever arms, the forces correspond to the actual forces in the joint (2). <IMAGE>

Abstract: In the semiconductor memory composed of divided dynamic memory cell arrays when a drive signal is supplied to a word line selected by a row decoder, data stored at the memory cells connected to the word line are transferred to bit lines, respectively. A change in potential at the bit line pair is amplified by the sense amplifier to completely read the data. To prevent the bit line pairs from being sensed erroneously due to fluctuation of the timings at which the word line driving signals are generated in the divided cell arrays, a bit line sense signal is generated a predetermined delay time after all the word line driving signals have been generated, in order to drive all the sense amplifiers simultaneously, so that data can be definitely read from the memory cells to the bit lines. To detect that all the word line driving signals have been generated, a drive signal detection circuit (7) is connected between word line driving circuits (6a, 6b, ... 6n) for all the divided cell arrays and a delay circuit (10) connected to a sense amplifier driving circuit (11).

Abstract: An incoming data signal (101) including so-called gaps is synchronized to a new outgoing clock signal by employing a single elastic store (103) and a smooth write address. An elastic store write address (107) is generated in response to an incoming clock signal (105) and is inhibited from advancing during the gaps in the incoming data signal. A smooth clock signal (108) is obtained by appropriately dividing (109) the incoming clock signal by a value dependent on the duration of the gaps in a predetermined portion of the incoming data signal. The smooth clock signal is used to control a counter (111) to generate a smooth write address. The smooth write address is supplied to a phase detector (112). An adjusted read address (117) is generated in response to the new outgoing clock signal and is supplied to the elastic store and to the phase detector. A counter (117) used to generate the adjusted read address is inhibited from advancing during intervals in which gaps are to appear in the output data signal from the elastic store. A stuff decision is made at predetermined stuff decision points which are strategically placed relative to the positions of the gaps to be inserted in the outgoing data signal so that apparent jumps in a write-read separate signal generated by phase detector do not affect the stuff decision.

Abstract: For the enhancement of toner release from an imaging surface on a flexible belt member (10) in an electrophotographic device a resonator suitable for generating vibratory energy is arranged in line contact with the back side of the belt member, to uniformly apply vibratory energy to the member. The resonator includes a horn (152) divided into a linear array of segments (158b), and an array of vibration producing elements (150a), each coupled to at least one horn segment, and driven with a voltage to produce a high frequency vibratory response. To avoid the problem of roll-off in response that occurs at the outer segments of the array of horn segments, the vibration producing elements coupled to the outer horn segments are driven with a higher voltage than those coupled to horn segments in the central portion of the array.

Abstract: An ultrasonic diagnostic imaging system is provided for scanning with a linear transducer array and displaying an image area which is truncated with respect to a conventional triangular image sector to take the form of a trapezoid. Uniformity of image resolution and ease of signal processing enhancement is provided by transmitting adjacent ultrasonic beams at equal angular increments over the sector area. The ultrasonic beams transmitted are focused around predetermined transmit focal points and the transmit aperture employed for each transmission is determined by a transducer sensitivity criterion applied to the focal point. Means are provided for delaying signal components received from the beam directions so that the sum of the components will form a coherent echo signal. Means are provided for dynamically focusing received signal components by dynamically focusing received signal components by dynamically varying the sampling frequencies of laterally disposed signal components, and the receive aperture is dynamically varied in correspondence with the number of array elements which satisfy a sensitivity criterion at different depths of field.

Abstract: In a method and apparatus for continoulsy producing a heated roll-shaped food, a horizontal type of cylindrical or bell-shaped heating drum is rotated and heated while coated with a scorch-retarding oil film on the inner peripheral surface thereof and raw material is poured onto the inner peripheral surface thereof. The raw material is heated while spreading out on the inner peripheral surface of the heating drum with aid of fluidity of the raw material and the rotation of the drum. The heated raw material swells up along the inner peripheral surface of the heating drum, and is exfoliated from the inner peripheral surface due to its weight and reversed at a head edge portion thereof. Thereafter, the exfoliated and reversed tip edge portion of the gelled raw material is overlaid over a portion of the raw material which continuously swelling up to thereby form a core of the overlaid portions of the raw material and the continuously swelling raw material is rolled up around the overlaid portions serving as the core by means of its weight and an angular moment which is applied to the overlaid portions of the raw material due to the rotation of the heating drum. Finally, a roll-shaped product is taken out from a tip portion side of the heating drum. All of the above steps are continuously carried out.

Abstract: A digital communication network has a plurality of remote terminals (RTs) which communicate with a plurality of base stations (BSs) by radio links operating at a single frequency. Each RT monitors the signal strengths of outbound messages and keeps an ordered table indicating which BSs produce the highest strength signals. At sign-on, an RT sends a message to the BS at the top of the list. The message includes the first predetermined number of entries at the top of the list. Each BS monitors the number of RTs it can hear and the number of users attached to each BS. The BS to which the sign-on message is sent then decides on the basis of signal strength, number of users attached, and BS coverage which BS should be attached to the particular RT and then notifies a communications controller. Such decision thus levels the workload. Each RT monitors errors and requests re-evaluation of attachment when the error rate for the BS to which it is attached exceeds a predetermined value.
