Abstract: A spark plug has a pressure detector (2) which includes a diaphragm (214) and semiconductor strain gauges. The diaphragm is provided in the vicinity of the combustion chamber within the housing (7) and extending substantially in the axial direction of the housing to thereby form a reference chamber separated away from the combustion chamber and to thereby generate a strain due to a differential pressure between a pressure within the combustion chamber and a pressure within the reference chamber. The semiconductor strain gauges are formed in the diaphragm for changing its electrical signal in accordance with the strain of the diaphragm.

Abstract: An ultrasonic inspection and imaging instrument is characterized by storing reduced image examples (images by means of reduced image display data obtained by scaling down picture display data) of an ultrasonic measurement picture beforehand, together with measurement conditions at the time the measurement picture is obtained prior to a scale-down imaging process. When the measurement is started or the measurement conditions are otherwise changed, the measurement conditions are set as those obtained from the measurement picture prior to the scale-down processing with one of the reduced image examples thus selected as an index while a list of image examples is indicated on a display and read from a memory unit for ultrasonic measuring purposes. 
     When a reduced image example or what is similar to the example desired by an operator is selected, proper measurement conditions are automatically set in the ultrasonic inspection and imaging instrument. When the operator wants to change or switch the measurement picture, moreover, he/she is able to make ultrasonic measurement on confirming what the subsequent image is like or what an image is desired to be selected by means of the reduced image example beforehand.

Abstract: A method of welding stainless steel, such as a stainless steel end plug into a stainless steel nuclear fuel rod is disclosed. The welding process has a reduced arc wander and deeper arc penetration. A treated welding electrode for practicing the method also is disclosed. A layer of stainless steel is placed on the working arc discharge end of a nonconsumable tungsten arc welding electrode before welding. The stainless steel coating on the electrode reduces arc wander and permits deeper arc penetration. Approximately .001 to .005 inches of stainless steel is placed on the working arc discharge end of the electrode. The electrode coating can be formed by positioning the working arc discharge end of the electrode into close proximity to a grounded piece of stainless steel and then electrically shorting the electrode to the stainless steel so that the working arc discharge end sticks to the stainless steel. The working arc discharge end of the electrode is broken from the stainless steel so that a layer of stainless steel remains thereon.

Abstract: A scene recognition system and a method employing low and high level feature processing are disclosed. Image data is processed by a low level feature detection processor (31) that extracts low level features from an image. This is accomplished by converting a matrix of image data into a matrix of orthogonal icons that symbolically represent the image scene using a predetermined set of attributes. The orthogonal icons serve as the basis of processing by means of a high level graph matching processor (37) which employs symbolic scene segmentation, description, and recognition processing that is performed subsequent to the low level feature detection. This processing generates attributed graphs representative of target objects present in the image scene. High level graph matching compares predetermined attributed reference graphs (36) to the sensed graphs (35) to produce a best common subgraph between the two (35, 36) based on the degree of similarity between the two graphs (35, 36). The high level graph matching (37) generates a recognition decision based on the value of the degree of similarity and a predetermined threshold. The output of the high level graph matching (37) provides data from which a target aimpoint is determined, and this aimpoint is coupled as an input to a missile guidance system (24) that tracks identified targets.

Abstract: A method of knitting in pleats includes knitting a succession of surface knitted sections (A), fold-back knitted sections (B), and overlap knitted sections (C), with the use of arrays of knitting needles mounted on at least a pair of front and rear needle beds, one or both of which are arranged movable leftward and rightward. The fold-back knitted sections (B) are removed from the corresponding needles after fastening of thread ends. The surface knitted section (A) and/or the overlap knitted section (C) close to the needles, is or are displaced from which the fold-back knitted sections (B) are removed, so that they are located next to each other. A succession of the surface, overlap, and surface knitted sections (A, B, C) are loaded onto the array of needles on one of the two needle beds. After moving the other needle bed in a direction opposite to the fold-back direction of the fold-back section (B), the overlap or surace knitted section (A or C) is loaded onto the knitting needles of the other needle bed. After moving the other needle bed in the knitting direction of the fold-back knitted section (B), the overlap section (C) overlapped with the surface section through stitch shifting. The overlapped regions are bound in pleats.

Abstract: A variable wavelength light source or semiconductor laser device using a semiconductor laser element (1) suitable for use in optical communications is provided. Light (b') emittted from one end surface of the semiconductor laser element (1) is led along a path through a light wavefront converting element (Fresnel lens) (20) and a spatial light modulating element which are both formed in a waveguide layer, to a diffraction grating which is also formed in the waveguide layer (6). Light reflected from the diffraction grating (30) is caused to travel back along the same path but in the opposite direction and to impinge on the semiconductor laser element (1). Wavelength selection of the spatial light modulating element and the diffraction grating (30) is utilized for generating and maintaining oscillations at a selected wavelength in the laser element (1). The selection of the wavelength of light is done by selecting a wavelength of surface acoustic wave (8) of the spatial light modulating element by changing the frequency of a high frequency electrical signal applied to the modulating element.

Corresponding amplitude sample signals are integrated and stored in a plurality of registers (96) and for each symbol, the register (96) storing the maximum value is ascertained to identify the associated sample number, which is stored in a sample number register (160). This sample number is utilized to determine the time of a symbol clock signal (RXCLK) used for clocking the received data.

Abstract: A method of controlling the current in a resistance welding arrangement, in particular a multi-spot system, is proposed. The primary current is adjusted by means of thyristors by phase-shifting control. According to the method, the phase lag (32) between primary current I (31) and primary voltage (30) is measured during every half wave of the primary voltage (30). The value determined for the phase lag is compared with the value provided for the following thyristor ignition angle. If the value of the phase lag (32) is greater than the intended ignition angle, the intended ignition angle is confirmed, otherwise a new ignition angle dependent upon the value of the phase lag (32) is set. For the calculation of the ignition angle ( alpha ), the voltage-time area belonging to a half wave is conveniently determined by that area being determined which in the representation in a voltage-time diagram is enclosed by the primary-voltage curve belonging to a half wave and by the zero line of the primary voltage (30). <IMAGE>
