Title: Speech coding system
Inventor: SERIZAWA MASAHIRO
IPC: G10L19/12
Filed: 1993-02-23
Granted: 1998-08-04
Abstract: An input speech signal is splitted into a time section and generating the splitted signal as a speech vector and LPC coefficient sets are developed by linear prediction analysis for every time section of the speech vector. The speech vector is weighted based on the developed LPC coefficient sets, then a plurality of the weighted speech vectors are connected and the connected speech vector having a predetermined frame length is generated.          An excitation codevector whose weighted synthesized signal is the most similar to the weighted speech vector is determined among from a plurality of excitation vectors each having the frame length which are previously stored as a sound source. A plurality or adaptive codevectors each having the frame length and obtained by cutting out a sound source signal produced from the determined excitation vectors at predetermined timing points are stored in an adaptive codebook. An adaptive codevector whose weighted synthesized signal is the most similar to the weighted speech vector is determined among from the plurality of adaptive codevectors.

Granted: 2004-08-03
Abstract: A print material handling system is described which comprises an input tray, and an output tray, with the trays having at least one common side wall which is adjustable laterally relative to the other side wall such that adjustment of the moveable side wall simultaneously adjusts the width of the input and the output trays.  As the moveable wall is adjusted, the support structures defining the bottom of the input and the bottom of the output tray are simultaneously adjusted such that the input and output trays support print material of various widths. Additionally, the invention includes at least one retractable wing positioned on one of the side walls. The wing can be manufactured in a relatively narrow width because the wing will always be positioned adjacent a print material side edge due to the simultaneous adjustment of the input and output trays.

Title: Monitor screen-integrated video camera
Inventor: IKEDA HIROSHI
IPC: H04N5/445
Filed: 1994-07-07
Granted: 1997-10-07
Abstract: An address for a character generator ROM is composed of an upper readout address portion which is a character code loaded from a text memory for storing texts edited by a microcomputer and a lower readout address portion which is a value of a counter. Output data from the character generator ROM accessed by the above addresses are loaded in parallel by left-shift and right-shift registers. The output data is serialized by the left-shift register to form character pattern data, which in turn is superimposed on a video picture signal to be outputted to a VTRportion. In response to a self-image picture-taking mode signal, a selector selects as an output either the output of the left-shift register or the output of the right-shift register. The thus-selected output is superimposed over the video picture signal for delivery to a monitor screen driver circuit. The monitor screen driver circuit horizontally-inverts the scanning direction in order to display a mirror-image of the picture on the monitor screen when the video camera is operated in the self-image picture-taking state.

IPC: H05K3/30
Filed: 1994-10-28
Granted: 1999-08-31
Abstract: An apparatus for and a process of batch assembly of sundry leaded or padded devices, encapsulated and non-encapsulated, onto a printed wiring board (PWB), which exhibit significant improvements in both manufacturability and reliability. A pressure frame assembly apparatus permits an application of uniformly distributed pressures to a variety of leaded packages and padded semiconductor chips during cure of conductive adhesives (AdCons), and leads to the reduction of variations in initial interconnection resistance, and thereby to the enhancement of the reliability of AdCon interconnections. The pressures are applied to the devices by an external application of a fluid under pressure to a flexible, resiliently stretchable membrane which conformably envelops outlines of the devices and adjacent areas of the PWB. Application of vacuum suction to within the cavity, formed by the pressure frame and the membrane, prior to the external application of the fluid pressure to the membrane, further improving the reliability of surface mounted assembly of packages on the interconnection board. Assembly yields approaching 100% were observed for a variety of surface mounted packages indicating that thesystem will be highly reliable.

Abstract: A low bit-rate (192 kBits per second) transform encoder/decoder system (44.1 kHz or 48 kHz sampling rate) for high-quality music applications employs short time-domain sample blocks (128 samples/block) so that the system signal propagation delay is short enough for real-time aural feedback to a human operator. Carefully designed pairs of analysis/synthesis windows are used to achieve sufficient transform frequency selectivity despite the use of short sample blocks. A  synthesis window in the decoder has characteristics such that the product of its response and that of an analysis window in the encoder produces a composite response which sums to unity for two adjacent overlapped sample blocks. Adjacent time-domain signal samples blocks are overlapped and added to cancel the effects of the analysis and synthesis windows. A technique is provided for deriving suitable analysis/synthesis window pairs. In the encoder, a discrete transform having a function equivalent to the alternate application of a modified Discrete Cosine Transform and a modified Discrete Sine Transform according to the Time Domain Abasing Cancellation technique or, alternatively, a Discrete Fourier Transform is used to generate frequency-domain transform coefficients. The transform coefficients are nonuniformly quantized by assigning a feted number of bits and a variable number of bits determined adaptively based on psychoacoustic masking. A technique is described for assigning the Fated bit and adaptive bit allocations. The transmission of side information regarding adaptively allocated bits is not required. Error codes and protected data may be scattered throughout formatted frame outputs from the encoder in order to reduce sensitivity to noise bursts.

Title: Method for crown plating a camplate and a metal-plated camplate formed thereby
Inventor: TOMBERS MICHAEL D
IPC: F02B3/06
Filed: 1995-01-31
Granted: 2000-06-13
Abstract: A method is provided for improving the load distribution on a ramp surface of a clutch mechanism, such as the camplate of an overrunning clutch for the turbocharger of a locomotive diesel engine. In addition, an improved camplate produced by such a method is also provided in accordance with this invention. The method involves an electroplating process in which the electrostatic field is uniquely shaped so as to concentrate the electrostatic flux at a central region of the ramp surface, such that a greater amount of plating metal is deposited in the central region of the ramp surface as compared to the edges of the ramp surface. As a result, the ramp surface has a crowned contour as defined by the plating alone, and does not require a pre- or post-plating crown grind operation. The crowned contour serves to advantageously distribute a load over the ramp surface, so as to promote a longer service life for the camplate.
