  • Publication number: 20020020233
    Abstract: A hybrid pipette including a pipette casing (11) and a slide shaft (22) vertically movable in response to the operation of a pushbutton (23). A plunger (31) is disposed below the slide shaft and urged upwardly by a spring (33, 34). An engagement member (41) is coaxially and movably fitted on the slide shaft (22) and extends through a hole (12a1) in a casing member (11) so as to be movable at least vertically. An electric motor (51) is provided on an axis different from the axis of the slide shaft and operatively engaged with the engagement member (41). In a manual operation mode, the slide shaft (22) and the plunger (31) move vertically in response to the operation of the pushbutton (23) to perform suction and discharge of a liquid. In a motor-driven operation mode, the engagement member (41) is driven to move vertically by the electric motor (51), whereby the plunger (31) is moved vertically to perform suction and discharge of a liquid.

  • Patent number: 5300166
    Abstract: A film is delivered from a delivery roller and another film is delivered from another delivery roller. The two films are introduced between a heater and a receiver. The heater presses the two films against the receiver to bond the films. Then, the rear end of the film is cut off with fusing and the front end of another film is cut off with fusing by wire heaters. The bonded film is transferred through drive and pinch rolls to an accumulator for storing the film and is spread to open slits by holding rolls to form a longitudinal web, which is laminated on a lateral web manufactured in another process to form a reticulate non-woven fabric.

  • Patent number: 5259097
    Abstract: A pair of stretching pulleys are rotatably mounted on a pair of support plates within a housing. A belt is wound around the upper part of the stretching pulley and a number of turn pulleys. A film introduced onto the stretching pulley is held between the belt and the stretching pulley and is transferred. Air flow generated by a fan and heated with a heater is blown against the film through a louver and circulates through bellows mounted to the housing to return to the fan. The stretching pulley is partially cooled in a water bath. The support plates are rotatably connected to screw shafts, thereby changing a distance and angle between the plates. The stretch width or stretch ratio of the film is thus adjusted with the change of the distance and angle.
