Patent EP-0682989-A2 (EP)
Inventor: SEYED-BOLORFOROSH MIR SAID
IPC: H04R17/08
Filed: 1994-09-21
Abstract: An ultrasonic transducer (10; 64; 80; 98) for controlling an elevation aperture utilizes the electric field-induced polarization properties of relaxor ferroelectric materials (12; 70; 82, 84; 110). The Curie temperature of the material is typically close to room temperature, so that the application of a bias voltage provides piezoelectric activity. By varying the thickness of a dielectric layer (18; 74; 92, 96 and 100-106) that spaces apart the relaxor ferroelectric material from an electrode (16; 66; 90, 94; 108) or providing the bias voltage, the piezoelectric activity can be tailored. That is, degrees of polarization of the relaxor ferroelectric material are varied spatially in correspondence with changes in thickness of the dielectric layer. The effective elevation aperture of the transducer can be varied by adjusting the bias voltage.

Abstract: An ECL to CMOS signal converter circuit including built-in toggle-fault detection circuitry and method of conversion are provided in which an RF transformer (420) is used to translate ECL level digital signals to CMOS level signals. A diode biasing circuit (CR₁,CR₂) shifts the average DC level of the CMOS level signals in a positive direction to avoid signal undershoot. An AC peak detection circuit is connected to the inactive leg (A) of the RF transformer (420) to monitor toggling of the ECL level input signal lines. A DC comparator circuit (430) compares the detected peak voltage with a predetermined threshold voltage, and generates an alarm signal representing a toggle-fault whenever the detected peak voltage is lower than the predetermined threshold.

Abstract: An apparatus and method for processing the input digital signal is disclosed. An input digital audio signal at an input terminal 11 is supplied via a one-block delay unit 17 to a difference unit 20, an output of which is processed by an annexed noise-shaping circuit 21 and restored by a near-instantaneous compressor 26, a near-instantaneous expander 27 and an accumulator 28 so as to be fed back to the difference unit 20 to find a difference between a signal of a directly preceding sample and a signal of the current sample. The annexed noise shaping circuit 21 modifies the spectrum of the quantization noise by taking aural characteristics, such as equal-loudness characteristics or masking characteristics, into account for diminishing the level of the quantization noise as perceived by the ear. The noise level as perceived may be reduced in a manner desirable for the sound quality without changing the existing format.

Abstract: A cassette case which allows positioning and fixing of a hub without biting of a hub pawl, and enhances the convenience with which the case is used. A plate-like portion comes at its edge into contact with a corner of a peak of a hub pawl without the plate-like portions of the projection coming at their edges into engagement with the hub pawl when a cover section of a storage case has been closed relative to a casing section. The sum of pushing forces exerted on the hub pawl by the plate-like portion causes the hub to rotate to thereby introduce the hub pawl into a space formed between the plate-like portions. In order to carry out the above-mentioned operation, the plate-like portion is designed to have an edge extending in a direction from a front to a rear, and vice versa, of a magnetic tape cassette to be encased in the storage case, and the plate-like portion is designed to have an edge making a predetermined angle with the above-mentioned direction.

Abstract: An electrical I/O connector is particularly suitable for docking-type connection applications and has a terminal block assembly held within a protective exterior casing. The terminal block assembly includes two interengaging halves which receive a plurality of metal terminals disposed thereon in a spaced-apart order. The terminals define two groups of terminals on each surface of the terminal block assembly halves and the two groups are defined by staggering the terminals lengthwise. A spacer is provided between the terminal block halves to maintain the terminals in their spaced apart order and includes projections which support insulation displacement terminals which extend from the terminals on opposite sides of the terminal block assembly. These insulation displacement terminals are arranged in a two separate tiers, which enable the connector to have an increased terminal density.

Abstract: A method, especially applicable on a continuous basis to commercial process streams, for treating unwanted by-products and/or impurities contained in those streams. The method comprises the reaction  in situ  of such by-products or impurities with a reagent, preferably selected for its reactivity under ambient conditions of the process stream, to produce one or more materials which may then be separated from the process by economical means. The treated stream may be recycled to the process for further processing. While the method is not limited as to the process to which it is applied nor to the reagent or reagents used, in one convenient embodiment, formaldehyde in aqueous solution is reacted with an alkali metal sulfite or bisulfite to produce the corresponding salt, which may then be separated essentially completely by, e.g., distillation or membrane separation, etc., or its concentration in the process may be controlled by, e.g., continuous removal of a purge stream, etc.

Abstract: A no-ID zone-bit-recording data recording disk drive system having an interface processor and a servo processor is described wherein track seek time is substantially reduced by the following two step seek process. The interface processor converts a logical block address (LBA) to an estimated physical block address (EPBA) using a defect map where the EPBA is communicated to the servo processor. The servo processor uses a zone table and converts the EPBA to an estimated zone-cylinder-head-sector (ZCHS) value which is used to initiate actuator arm movement and moving the appropriate head over the disk in the direction of sought after track. Concurrently with the servo processor computation and actuator arm motion, the interface processor generates an exact PBA and communicates the exact PBA to the servo processor. The servo processor converts the exact PBA to exact ZCHS values and modifies the actuator arm motion so the head can be exactly positioned over the sought after track. By allowing the servo processor to map PBA to ZCHS and further utilizing EPBA to initiate actuator arm motion before the exact PBA becomes available, substantial reduction in track seek time is attained.

Abstract: A traction control system for a vehicle, which, during normal driving of the vehicle, if a driven wheel speed becomes less than a deceleration-control starting reference value which is set lower than a vehicle speed, a feed-back control of an opening degree of a throttle valve is started so as to converge the driven wheel speed into a target driven wheel speed. If a downshifting is conducted, the feed-back control of the throttle valve opening degree is feed-back controlled by using, in place of the driven wheel speed, a pseudo driven wheel speed calculated based on the number of revolutions of an engine and a gear position. With this arrangement, it is possible to open the throttle valve at an earlier stage to increase a driven wheel torque, and to avoid a deceleration slip at the time of downshifting at a high speed.
