Title: Near-toll quality 4.8 KBPS speech codec
Inventor: TZENG FORREST FENG-TZER
IPC: G10L19/10
Filed: 1990-11-29
Granted: 1994-05-11
Abstract: A speech codec operating at low data rates uses an iterative method to jointly optimize pitch and gain parameter sets. A 26-bit spectrum filter coding scheme may be used, involving successive subtractions and quantizations. The codec may preferably use a decomposed multipulse excitation model, wherein the multipulse vectors used as the excitation signal are decomposed into position and amplitude codewords. Multipulse vectors are coded by comparing each vector to a reference multipulse vector and quantizing the resulting difference vector. An expanded multipulse excitation codebook and associated fast search method, optionally with a dynamically-weighted distortion measure, allow selection of the best excitation vector without memory or computational overload. In a dynamic bit allocation technique, the number of bits allocated to the pitch and excitation signals depend on whether the signals are "significant" or "insignificant". Silence/speech detection is based on an average signal energy over an interval and a minimum average energy over a predetermined number of intervals. Adaptive post-filter and the automatic gain control schemes are also provided. Interpolation is used for spectrum filter smoothing, and an algorithm is provided for ensuring stability of the spectrum filter. Specially designed scalar quantizers are provided for the pitch gain and excitation gain.

Title: Recording apparatus with ink jet recording head
Inventor: SHIMAMURA YOSHIYUKI
IPC: B41J2/165
Filed: 1991-02-13
Granted: 1994-10-05
Abstract: A recording apparatus for performing recording on a recording medium with an ink jet recording head (9) capable of ink jetting is described. The recording head is closed by capping after closure of power source or during waiting or when no data is provided from a host unit for a predetermined period of time. To ensure reliable capping, the position of carriage (11) carrying the head (9) is recognized. According to the invention, in case when jumping of teeth occurs in a carriage motor drive system gear (31) due to external disturbance of carriage running, the error that occurs in the carriage position recognition is held within one step so that there is no adverse effect on the capping executed during non-recording time such as then recording is ended or when absorbing recovering is executed. <IMAGE>

Title: Ultrasonic welding knit polyamide sheets
Inventor: PONS ROVIRA JUAN
IPC: D06H/
Filed: 1986-05-14
Granted: 1988-02-04
Abstract: Welding comprises setting the sheets between an ultrasonic oscillator and welding mould having a weld part to form a weld line, setting an ultrasonic transmitting layer between the ultrasonic oscillator and the sheets, applying a pressure to the ultrasonic transmitting layer via the oscillator, and moving the ultrasonic oscillator on the ultrasonic transmitting layer to transmit the pressure to the sheets through the ultrasonic transmitting layer. As a result, the sheets are cut along the weld line and welded. The ultrasonic transmitting layer may be formed softer than the welding mould, this allows the sheets to be cut, without damage. A shield layer may be put between the ultrasonic transmitting layer and the sheets so that no part of that layer contacts the sheets.
