  • Perforating machining method with laser beam
    Patent number: 6433304
    Abstract: Assuming that t1 represents a period of time until a detection signal is outputted after a sensor senses a laser beam passed through a through-hole of a workpiece, t2 represents a period of time until the detection signal derived from the sensor exceeds a preset threshold value, and t3 represents a period of time until radiation of the laser beam is actually stopped after the threshold value is exceeded, a total period of time (t1+t2+t3) of the periods of time t1 to t3 is set to be shorter than a time difference (T2−T3) between a pulse width (T3) and one cycle (T2) of a pulse signal for constructing a laser output command signal.

  • Seedling raising sheet, method of manufacturing same, seedling raising method, culturing method, and transplanter
    Patent number: 6240674
    Abstract: A seed top of foamed cells is constructed such that a porous sheet having open cells is affixed to one surface of a thin support band extending in a band-like configuration with its widthwise direction being an up-and-down direction, and accommodation recesses for accommodating seedling seeds are provided in the porous sheet. It is possible to reduce the size and weight of the seedling raising sheet used for raising seedlings and to eliminate the need for soil in raising seedling, thereby enabling an industrial mass-production of the seedling raising sheet.
