Abstract: An SOI-type insulated-gate FET is constituted such that an electrical resistance across pn-junction of the source region is less than that across pn-junction of the drain region, by being provided with a metal dopant, such as aluminum or tungsten; semiconductor dopant excessively doped more than normal source region; an amorphous source region; or a layer formed of a material having different thermal expansion coefficient from the thermal expansion coefficient of material forming the source region, upon the source region. In a thus fabricated transistor, there is generated a carrier generation centre or a precitipation of the impurities at a pn-junction formed between the source region and the semiconductor substrate. Thus, a current path is formed across the pn-junction of the source region in both the forward and reverse directions of a diode of the pn-junction so as to substantially eliminate the potential difference between the source region and the semiconductor substrate. Accordingly, a kink phenomena in the drain voltage-current characteristics is eliminated.

Abstract: A method for adjusting a spinning piezoelectric beam of a dual-axis angular rate sensor, in which the spinning piezoelectric beam is excited in a direction at right angles to the lengthwise direction of two piezoelectric sensors (22a, 22b) and to a rotary shaft (21); detected voltages of the two piezoelectric sensors (22a, 22b) are measured by a signal measuring circuit (30); a bending portion of at least one of the two piezoelectric sensors is ground so that the levels of the two measured signals and the difference therebetween become small; the spinning piezoelectric beam (20) is excited again in the lengthwise direction of the piezoelectric sensors (22a, 22b) at right angles to the rotary shaft (21); detected voltages of the two piezoelectric sensors are measured by the signal measuring circuit (30); and a weight mounted on the free end of at least one of the two piezoelectric sensors is ground so that the levels of the two measured signals and the difference therebetween become small. Thus, acceleration components applied to the spinning piezoelectric beam, in the detected voltages of the two piezoelectric sensors, are rendered to have the same phase and the same amplitude. On both sides of each piezoelectric sensor there are formed electrodes which are spaced 1.5 times the thickness of the sensor from support washers (24).

Abstract: The present invention refers to a system for calculating the DCT of dimension M*M with the property of being orthogonal and sepa­rable under the form of two monodimensional transforms calculated by a fast algorithm, by operating on incoming and outgoing words, that are disposed in the form of parallel bits, and by operating onto the data internal to the system onto words represented by means of 2 Mbits. 
     According to a feature of the invention, the operations of sum­mation and subtraction between variable data and the operations of multiplying by the variable data using fixed coefficients are made onto the data represented in the form of M couples of se­rialized bits, so that the speed of the incoming and outgoing words, in the form of words by parallel bits, is equal to the speed of bit couples that represent the internal data. 
     A circuit implemented onto silicon basis for the fulfilment of this system includes at least: 
- an input interface 
- a converter for incoming words for the conversion from the form of parallel bits to the form of words represented by means of serial bit couples for the incoming words and viceversa for the outgoing words 
- a first operator for the DCT monodimensional transform 
- a transpositor from lines to columns. 
- a second operator for monodimensional transform 
- a scaling device for outgoing words.

Abstract: In production of a gate oxide film of the MOS type semiconductor device, oxygen is added with trichloroethane to effect oxidation at a temperature from 1000°C to 1100°C so as to suppress generation of electron trap in the oxide film and interface trap which would be caused when electrons are injected into the oxide film. Alternatively, gas containing chlorine is dissociated to form a polysilicon gate electrode of the MOS type semiconductor device, and thereafter the chlorine is diffused into a gate oxide film by heating process, thereby suppressing generation of electron trap in the oxide film and generation of interface trap caused by injection of electrons into the oxide film.

Abstract: The process consists in moving all the needles of the machine into the lower cylinder before the forming of the pattern begins. The pattern is produced by moving a preset number of needles to knit at a feed of the machine so as to engage at least one pattern thread (3) which differs in color with respect to the background thread (5) used to form the region of the sock or stocking which is proximate to the pattern, so as to obtain a first pattern portion on a row of the sock or stocking. During the rotation of the lower needle cylinder, the pattern thread (3), engaged on the last needle moved to knit at this feed, is tensioned and progressively recovered and is then fed again to the same needles, or to contiguous needles, which are moved to knit at the same feed to form a new portion of the pattern row. When the pattern is complete, the pattern thread (3) is cut.

Abstract: A data processor (11) executes a table look-up and interpolate instruction which retrieves two adjacent table values from memory, interpolates between them and stores the result in a register. The same register contains, prior to the execution of the instruction, a value which is used both in calculating the address in memory from which the values are obtained and in performing the interpolation calculation. A major variant of the instruction involves obtaining the values to be interpolated between from registers, rather than from a table in memory. The combination of the two facilitates the performance of three-dimensional, or surface interpolations. It is also possible to select whether rounding is performed during the interpolation.

Abstract: A computer system is provided having apparatus (11) between a central processing unit (CPU) (19) and a peripheral device (15) which ensures compatibility between existing software for the peripheral device (15) and a CPU (19) of any speed. The apparatus (11) waveshapes read or write strobe signals in a transfer cycle between the peripheral device and the CPU (19) in order to ensure timing parameters of the peripheral device (15) are not violated by fast CPUs. If the waveshaping causes a change in the timing between first and second consecutive read or write strobe signals, the interface (11) provides a wait signal to the CPU for the purpose of instructing it to extend the transfer cycle of the second strobe signal. In the illustrated embodiment, an apparatus (11) according to the invention is part of a video subsystem connecting a microprocessor unit (MPU) (19) and a video digital-to-analog converter (video DAC) (15). Writing or reading color data to or from the video DAC occurs by way of the apparatus (11) of the invention. The MPU (19) is slowed while it writes or reads color data only when it is required to prevent violation of the timing parameters of the video DAC (15). In this regard, slower MPUs are not penalized by the invention since wait states are inserted into a transfer cycle only when it is necessary to re-space consecutive read or write strobe signals to prevent the violation of timing parameters.
