  • Patent number: 4452682
    Abstract: An apparatus for electrochemically measuring clinical emergency check items of blood for a short time by flowthrough system, using a small amount of whole blood as a blood sample, which comprises a blood pH/gas component sensor unit, an electrolyte component sensor unit, and/or a biochemical component sensor unit, arranged in series in this order, a sampler and these sensor units being communicated with one another through a blood sample flow passage or channel, each of the sensor units being provided with sensor electrodes and at least one reference electrode as electrochemical sensor means.Detected values from each of the sensor units are transmitted to a computer or calculator through a current amplifier and/or a differential amplifier for a differential voltage from the voltage of the reference electrode to compute pH, pressure, or concentrations from the detected values, and numerically displayed on a display device connected to the computer.

  • Patent number: 4413574
    Abstract: An automatic sewing machine wherein a plurality blocks of unit pattern information including many position data which are respectively corresponded to each of various unit stitch patterns such as letters, symbols, etc. are stored in memory means. In this machine a first manual means for selecting an individual unit pattern information from the plurality blocks of unit pattern information stored in the memory means in a desired order and a second manual means capable of determining at will an individual size, an individual inter-distance, and arrangement direction of the selected unit stitch patterns when they are formed on a workpiece are disposed in an operable manner by an operator.

  • Patent number: 4412640
    Abstract: An apparatus for attaching a plurality of studs on a flexible sheet material such as work fabric, leather or the like according to a desired pattern comprizes a holder for holding the sheet material, a supply device for supplying studs severally, a plastic working device including a punch and die set for attaching the studs on the sheet material, and a drive device for varying the relative position between the holder and the plastic working device. The studs may be supplied severally and attached sequentially to the sheet material while the relative position between the holder and the plastic working device is varied by the drive device.

  • Patent number: 4388884
    Abstract: An automatic sewing machine for forming a desired pattern on a workpiece by means of varying the position of a workholder for holding the workpiece in relation to a needle which is vertically reciprocated due to pattern data stored in advance in memory means. A sewing machine of this type is provided with a manual input device for setting up a numerical limit indicating an allowably movable sphere of the workholder without impacting or interfering with the needle and a controller for calculating a numerical result indicating the movement amount of the workholder in relation to the needle during the pattern forming operation based on the pattern data prior to the pattern forming operation. The controller makes a comparison of the calculated numerical result with the numerical limit set by the manual input means, and generates a signal for warning the operator of the exceeding, if so being the case, of the calculated numerical result over the above-mentioned set numerical limit.

  • Patent number: 4388883
    Abstract: An automatic embroidery or stitch pattern sewing machine provided with a memory for storing plural blocks of cell pattern information respectively including zone data related to figure and location of a triangular or quadrangular zone on which a cell stitch pattern is to be formed, and a manual input device for setting up desired number of stitches to be formed in the zone. Based on the position data stored in the memory and the stitch number data set by the manual input device, a microprocessor connected thereto calculates the position data of the actual stitch forming positions; and a drive mechanism relatively moves the needle and the workpiece according to the position data calculated. Many cell stitch patterns thus formed on the workpiece turns out to be a desired unit stitch pattern such as a letter, symbol and other patterns.

  • Patent number: 4383489
    Abstract: A sewing machine provided with a needle capable of vertically reciprocating as well as laterally oscillating, a workholder so disposed as to be movable, in an X-Y coordinate plane which is in substantially right-angled relation with the needle, in the direction of the X axis and the Y axis, and memory means for storing data for controlling the oscillation movement amount of the needle and the shift amount of the workholder. The workholder is disposed in such a posture that each movement direction of X axis and Y axis thereof intersects the oscillation movement direction of the needle, whereby embroidery or stitch patterns of letters, symbols, and other patterns can be formed on the workpiece held on the workholder exclusively with slant stitches at a predetermined angle against a horizontal reference line of the letters, etc.
