Patent EP-0442540-A2 (EP)
Inventor: COMPTON RONALD E
IPC: B23B21/00
Filed: 1986-04-17
Abstract: A turning machine (40) includes a control and mechanism for positioning the turning tool (56) on the head. A CNC (58) issues command signals for selectively positioning the tool on the head (82). These signals are developed from an encoder (66) which provides the instantaneous position of the rotating part (42) being turned and from a program in the CNC containing information about the part. A closed loop control system (80) receives these command signals and converts same into a control current for a linear motor (72) which is the prime mover controlling the positioning of the tool on the head. The linear motor operates a carriage (128) on the head and the cutting tool (56) mounts on the carriage opposite the connection of the linear motor to the carriage. The carriage is a hollow bar guided on the head by sets of rollers which are cooperatively arranged to provide yieldably forceful constraint of the bar. The rolling action of the bar on the head provides a low friction, low inertia construction enabling rapid response to CNC commands.

Abstract: In order to structure a ground metallic material surface of an impression cylinder (1) electroplated with hard chromium, a thin layer of alkali-resistant negative resist material is first applied to the metallic hard-chromium surface of the impression cylinder (1), a positive screen film is then brought into contact with the alkali-resistant negative resist layer and the latter is irradiated through the film using an ultraviolet light source. In this process, subareas of the alkali-resistant negative resist layer are cured by the light passing through the transparent parts of the film, then unirradiated parts of the negative resist layer are removed with an organic solvent developer and, finally, the hard-chromium layer uncovered after the development process is anodically hollowed out electrolytically in cup fashion through the openings of the alkali-resistant negative resist layer left behind as a network using sodium hydroxide solution. The hydroxide solution is sprayed on through a narrow iron-screen hollow cathode (9) arranged along the impression cylinder (1) at a short distance from the material surface.

Abstract: A method and apparatus are disclosed for speech analysis and speech recognition. Each speech utterance under examination in accordance with the method of the present invention is digitally sampled and represented as a temporal sequence of data frames. Each data frame is then analyzed by the application of a Fast Fourier Transform (FFT) to obtain an indication of the energy content of each data frame in a plurality of frequency bands or bins. An indication of each of the most significant frequency bands, in terms of energy content, are then plotted by bin number for all data frames and graphically combined to create a power content signature for the speech utterance which is indicative of the movement of audio power through the audio spectrum over time for that utterance. By comparing the power content signature of an unknown speech utterance to a number of previously stored power content signatures, each associated with a known utterance, it is possible to identify an unknown speech utterance with a high degree of accuracy. In one preferred embodiment of the present invention, comparisons of power content signatures from unknown speech utterances are made with stored power content signatures utilizing a least squares fit or other suitable technique.

The feedrate may be controlled on the basis of preset rules within a single block without dividing a machining path into a plurality of blocks for controlling the feedrate, the preset rules being changeable by an operator whereby his machining know-how can easily be incorporated into the machining program. Rules incorporating machining know-how are set in a knowledge storage section, an inferring section is provided independently of the knowledge storage section to ensure ease of additions and corrections to the rules, and the inferring section synthesizes the results of inference provided by a plurality of rules and deduces a final conclusion, whereby complex control can be easily achieved with various factors taken into consideration. Rules set in the knowledge storage section can be described in a production rule format, allowing a final conclusion to be achieved by fuzzy inference. In such case, efficient processing is enhanced by providing that inference is only made as to rules judged as necessary to be executed, membership functions in the conclusion part of a fuzzy rule are represented in a simple shape pattern, the results of all selected rules are considered and the relative significance of the selected rules are reflected on a conclusion.

Abstract: An apparatus and method electronically registers or aligns ideal raster data to real raster data for subsequent processes such as inspection systems and defect detection systems. The electronic image registration system receives ideal and real images in scrolling stacks or buffers wide enough to hold the width of the image and high enough to hold the difference in a skewed image. In other words, the real and ideal upper corners must be contained within the stacks for any kind of misalignment or distortion. Each stack has a "funnel" to randomly access frames of image in the vertical direction. Each stack image frame is moved horizontally out of its lower swath and into its new position in the next upper swath. Horizontal movement of each stack is independent, such that adjustable sequential access in the horizontal direction is available. The real image stream stack funnel addressing and clocking are held fixed during the registration phase, while the ideal image stream stack funnel address and clocking are in constant adjustment.

Each latch arm (116) terminates forwardly, in a latching head (134) which lies beneath a side wall (132) of a hood (60) enclosing the forward end of the housing (8). The remainder of each latch arm (116) is substantially coplanar with the hood side wall (132) whereby the latch arms (116) are in-line with the housing (8). The latch arms (116) are connected to the housing by way of the bight (122) of the strap (118). The in-line location of the latch arms (116) avoids the tangling with leads extending from terminals when the housing has been loaded with terminals.
