To this end the image is repeatedly scanned by means of radiation emitted by radiation projecting means that are transported at a constant scanning speed from a boundary outside the image beyond the image portion to be stored.

Abstract: A data processor for chromatography operates to separately recognize the peaks of a composite peak of a chromatogram. At first, in order to separate the peaks, the maximum point of the peak of the chromatogram is determined, and extrapolation lines are drawn from said maximum point to the individual points of the chromatogram, and then the gradients of the lines changing from the minimum to the maximum are determined. By determining the changes of the gradients of the extrapolation lines and intersection points of the extrapolation lines and the chromatogram, the major and minor peak are separated so that the shoulder peak can be judged remarkably accurately.

Abstract: The present invention provides for a process and apparatus for detecting the level of a liquid in a vessel. The method involves sensing the pressure head of the liquid level in column disposed with the vessel wherein the column liquid level has been adjusted to a first predetermined level. The level in the column is then adjusted to a second predetermined level. The pressure head of the second predetermined level in the column then sensed. The pressure of the liquid head in the vessel outside the column is sensed. The three pressure values are then used to determine the liquid level in the vessel.

Abstract: The speed of a motor or a moving body driven by a motor is detected by interpolating by an estimated speed, the speed between pulse signals generated by a pulse generator. The estimated speed is obtained by updating a variable representing the torque disturbance obtained by compensating for a variable representing a motor torque by a variable representing a torque disturbance synchronously with a clock pulse of a predetermined interval, and the initial value of the estimated speed and a compensatory amount of the torque disturbance is updated each time the pulse generator generates a pulse. In the prior art, the mean speed of the present pulse signal section was regarded as the initial value in the immediately following pulse signal section, while in the present invention, the real (spontaneous) speed is obtained when the pulse generator generates a pulse signal, and this real speed is regarded as the initial value of the estimated speed of the immediately following pulse signal section.

Abstract: A method for increasing the wirability of complementary metal oxide semiconductor (CMOS) differential cascode voltage switch (DCVS) logic circuits which comprises designing the circuitry to permit as many of the internal tree connections as possible to be wired using diffusion techniques. The method utilizes differential pair and load microblocks which have been designed so as to allow mirroring on a vertical center line. Utilizing the availability of mirroring for individual pairs plus relocation of individual pairs in the logic tree the crossings may be largely eliminated in a shortened period. It utilizes a step by step row and column analysis of the initial or starting tree design resulting from the basic Boolean logic to be performed by the particular circuit and makes required load mirroring and differential pair relocation decisions in an iterative process. The transistor pairs and load devices may be mirrored about a vertical center line.

Abstract: An arrangement is described for the selection of a tariff level "n" by repeated actuation of a key T1 or T2, which can be actuated in series, whereby the desired tariff level is adjustable by forward switching or reverse switching. Each selected tariff level is displayed immediately after detecting the key actuation by an allocation sentinel (27) in a display (10), and the start of a waiting time, which can be preset, can be triggered in each tariff selection. After the expiration of the waiting time, a parameter assigned to the last selected tariff level appears in the fare display field (26) and, accordingly, signals the acceptance of the last selected tariff level including the activation of all of the rest of the parameters assignable to the selected tariff level. It is possible, thereby, to select a tariff level by skipping over undesired tariff levels without the fare display being changed during the selection process.

Abstract: A display method in a computer tomographic apparatus is disclosed wherein a plurality of bar graphs representing the scanning schedule are generated on a display. The bar graph depicts the scanning time extending one distance and the margin time extending a second distance at a smaller width. When the scanning is taking place, signals are generated to plot over the scanning bar graph during the scanning time and plot over the margin bar graph during the margin time. The scanning time and margin time bar graphs adjoin one another and are distinguishable by the margin time extending from the scanning bar at a narrower width. This configuration allows an operator to readily determine at a glance the scanning step and progress thereof.

Abstract: Light transmitted through a thin section of reservoir rock whose pores are filled with blue-dyed epoxy is passed sequentially through red, blue and green filters and the density levels in the filtered images thereafter converted into pixels.

From the calculated values of intensity, hue and saturation, the pixels representative of pores and pores underlain by mineral are separated from the non-pore representative pixels.

Abstract: In such an operation mode that the vehicle is accelerated upon turning-on of the switch and, when the vehicle has reached a given vehicle speed, the switch is turned off to memorize the vehicle speed at that time for effecting constant-speed control at the memorized vehicle speed, a throttle valve is returned to apply the engine brake after turning-off of the switch. If at least one of several given conditions is satisfied, adjustment of opening degree of the throttle valve is started so as to maintain the current vehicle speed at the goal vehicle speed. This makes smaller overshoot of the controlled vehicle speed caused by a response deley of the vehicle. The given condition may be related to differences between current speed and set speed, elapsed time, elapsed distance, or degree of acceleration.
