Abstract: A method for measuring the liquid mass flow rate exiting a two phase (gas/liquid) feed nozzle includes determining the Power Spectral Density from the output of an accelerometer in close proximity to the restriction orifice controlling the gas flow, or of a pressure transducer in contact with the gas flow on the downstream side of the restriction orifice, and determining the area of the Power Spectral Density over a frequency band including at least one gas flow peak(s). 
     The liquid flow can then be obtained from a predetermined correlation between different magnitudes of the area and corresponding liquid mass flow rates.

Abstract: An EDM machine comprises a machining tank which moves along X-axis. An upper guide and a lower guide are formed integrally with a Y-axis moving block. The Y-axis moving block moves along a pair of rails that are placed on a horizontal plane. The horizontal plane is formed on a column within which portions of the upper and lower arms are located. By having the moving block move on rails that are placed on a horizontal plane, rattling of the moving block is eliminated and the machining accuracy is improved. The workpiece is also more accessible due to the machining tank moving in only one direction and since portions of the lower and upper arms are located within the column.

Abstract: ROM memories made in MOS or CMOS technology with LDD cells may be programmed advantageously in a relatively advanced stage of fabrication by decoupling an already formed drain region from the channel region of cells to be permanently made nonconductive (programmed) by implanting a dopant in an amount sufficient to invert the type of conductivity in a portion of the drain region adjacent to the channel region. In CMOS processes, the programming mask may be a purposely modified mask commonly used for implanting source/drain regions of transistors of a certain type of conductivity. By using high-energy implantation and a dedicated mask, the programming may be effected at even later stages of the fabrication process.

Abstract: A command identifying circuit separates entered image information into a bitmap command representing a line image and an image command representing a half-tone image. A data separating circuit separates layout information, bitmap data and paint-tone data from the separated bitmap command and, in accordance with the layout information, stores the bitmap data in a bitmap memory and the paint-tone data in a block-tone memory. Another data separating circuit separates layout information and image data from the separated image command, and a character/line-image extracting circuit extracts pixels, which constitute a character or line image, contained in the image data separated by the data separating circuit, and stores positional information and tone data regarding the extracted pixels in the bitmap memory and block-tone memory. However, pixels constituting a character or line image are not extracted in an image area within which a line-image area and a half-tone image area overlap each other. An extracted-pixel substitution circuit substitutes prescribed data for a portion of the image data in which a character or line image has been extracted, and a coding circuit codes the image data that has undergone substitution and stores the coded data in an image memory. By thus processing image information in an image processing method and apparatus in which a line image and half-tone image are mixed in one screen and stored, bitmap data is capable of being handled and image data read out of each of the memories may be combined in synchronism with a synchronizing signal from a printer engine. As a result, when text data or the like is outputted to the printer engine, it is unnecessary to combine a line image (characters or graphics) with a half-tone image [such as a photograph having tones (colors)] in a host computer or the like.

Abstract: An improved approach for breaking the bit lines of a semiconductor memory device into small pieces, referred to herein as Embedded Access Trees (EATs), is introduced. Embedded Access Trees enjoy the principal advantage of the banked approach by dividing long bit lines into several smaller bit lines to decrease the effective load which a selected cell must drive. However, EATs avoid most of the limitations of the banked approach, e.g., increased size, power and complexity. In a preferred embodiment of the invention, EATs are embedded into the existing full array and do not require additional peripheral decoders, MUXes or complex and costly global routing. For a given processing technology, the present invention permits a full memory array to be subdivided into more subarrays than the banked approach, with corresponding performance improvements.

Abstract: A method and a device are disclosed, during which a quantitatively proportional analysis sample of less than 50 ml can be taken from a milk flow, even in the case of cows having an expected total milk quantity of up to 30 kg and expected maximum milk flows of 12 kg per minute. The method is in this case distinguished in that, by using a cyclically controlled valve, each cycle comprising a valve open time and a valve closed time, for taking only analysis samples kept below a predetermined maximum quantity of 50 ml, from the empirically determined expected value of the total milk quantity to be milked from the cow in question, a cycle time and a valve open time are determined, the cycle time and the valve open time being in each case selected such that they lie within predetermined value ranges, such that the valve open time or the cycle time are controlled as a function of the milk flow, and such that, in order to avoid values of the valve open time or of the cycle time lying outside the value ranges, as a result of change in the milk flow, the valve open time and the cycle time are changed in the same ratios with respect to the values lying within the value ranges. The device, by means of which such a milk sample collection can be carried out, comprises a milk flow meter, a processor unit and a milk-sampling device which essentially comprises an electrically controllable solenoid, using which a closure member can be moved into a first position which blocks a flow orifice for the sampling flow and a second position which uncovers this orifice. <IMAGE>

Abstract: A low power optional inverter uses P-channel and N-channel transistors in series as in a conventional CMOS inverter, but in one embodiment connects complementary signals to the sources of the P-channel and N-channel transistors. Therefore, when the complementary signals are switched the circuit switches between an inverting and a non-inverting buffer. In the non-inverting mode, there is negligible current drain upon switching because in this mode the circuit does not include a standard CMOS inverter, and there is no conducting path from power to ground when input voltage is in the range of 2 to 3 volts. In one embodiment, in the noninverting mode, at least one bypass transistor between the optional inverter input and output is turned on, and power is not supplied to the inverter. In yet another embodiment, in the inverting mode a CMOS inverter is powered with conventional voltages and in the noninverting mode the CMOS inverter is disabled and a bypass transistor connects input to output.
