Abstract: In a cell analyze apparatus, a light beam is irradiated onto cells (or particles like the cells) flowing through a flow cell so as to measure cell light information for each cell with respect to a plurality of parameters (for example, the forward scattered light intensity, the right angle scattered light intensity and the intensity of fluorescence by different dye). Based on a minimal point of a histogram associated with the cell light information with respect to one or more parameters, the cell population is subdivided into fractions. When the minimal point is missing in the histogram, the parameters above are converted by use of a predetermined conversion expression (for example, a coordinate conversion is effected on the parameters) such that a minimal point is detected from the histogram of cell light information related to the new parameters obtained by the conversion, thereby subdividing an objective cell population.

Abstract: An IC card is provided with a data storage area for storing data, an identification code area for storing a plurality of identification codes and directories for storing information indicating which of the identification codes is an identification code authorized to access the data.When an identification code and information for identifying data are applied so as to make access to a data area in the IC card from the outside of the IC card, the IC card references the directories, recognizes which of the identification codes is an identification code authorized to access data, corresponding to the externally applied information for identifying data, and determines whether or not the identification code corresponds to the externally applied identification code.

Abstract: A programable controller includes a cycle time setter, a counter, and a calculator. The cycle time setter sets a cycle time for one round of execution of a sequential series of processing routines. The counter counts an execution time between the start of a first predetermined processing routine of the series and the termination of a second predetermined processing routine of the series subsequent to the first. The time difference between the execution time counted by the counter and the cycle time is calculated and, if positive, is allocated to execution of the remainder of the processing routines in the series.

Abstract: An imaging device is formed by a transparent substrate having opposite surfaces on which are formed a plurality of micro aspherical lenses. The axes of the lenses on one surface coincide with the axes of respective lenses on the other surface.

Abstract: A first device (1) and a second device (2) can be communicated by an electromagnetic coupling. Data to be transmitted from the first device to the second device is converted into pulse signals of different duty ratios in accordance with the H or L level of the transmission data. Further, the oscillation of an oscillator (15) of the first device is intermittently performed in accordance with the H/L level of the pulse signal. Switching elements (39, 40) are provided for a resonance circuit (30) provided in the second device. When data is transmitted from the second device to the first device, the switching elements are turned on or off in accordance with the data. Thus, the electromagnetic coupling is intermittently performed. The oscillator of the first device at that time intermittently executes the oscillation at a third duty ratio.

Abstract: A multivalued Arithmetic Logic Unit (ALU) is composed of a multivalued signal source, a memory array, a selection array, an AND array and an output circuit. The multivalued signal source generates signals each of which represents a logic value of multivalued logic. The memory array is provided with an address line group for each and every function to be inplemented, each address line group comprising a number of address lines. Which multivalued logic signals will appear on the address lines of each address line group depends upon a program based on the truth table of the corresponding function. Any one of the plural address line groups is selected by the selection array, to which a signal designating the function to be implemented is applied. One address line in the selected address line group is selected by the AND array, which has an input signal applied thereto, and the logic value signal on the selected line is delivered via the output circuit.

Abstract: In an electronic blood pressure meter for measuring blood pressure from a finger, there is provided a photoelectric sensor including a light emitting element and a light receiving element for detecting pulse wave components from a finger placed in a cuff. Since the variation of the DC component of the pulse wave from one person to another may exceed the linear range of pulse wave measurement, the brightness level of the light emitting element is adjusted according to the level of the DC component contained in the output from the light receiving element. Thereby, favorable extraction of the variational component of the pulse wave is made always within an accurate range of pulse wave measurement.
