摘要:
A device for advancing and retracting a writing element in a writing instrument, of the type comprising a cylinder, a stationary cam provided on an inner surface of the cylinder, a rotary cam follower disposed inside the stationary cam to be rotatable and slidable axially of the cylinder, the rotary cam follower being in abutting engagement at a front end thereof with the writing element, and a knocking rod disposed in the cylinder and having a front cam portion. When the knocking rod is pushed forward, the knocking rod, the stationary cam and the rotary cam follower cooperate to advance the writing element and maintain the same in an advanced position and to allow the writing element to retract to a retracted position. The knocking rod has projections which are in slidable engagement with slots formed axially through the cylinder. The knocking rod has slots to make it resilient. The knocking rod is inserted into the cylinder through the rear opening of the cylinder until the projections snappingly engage the slots. The capability of inserting the knocking rod from the rear side makes the assembly easy and simple.

A fetal movement information processing device and method for accurately grasping and predicting the healthy development state of a fetus, namely, the well-being state of the fetus by adequately detecting and recording information on the fetal movement of a pregnant woman. The fetal movement information processing device comprises detected information storage means (20) for storing fetal movement detection signal detected by a fetal movement sensor (11) and detection day information associated with the fetal movement detection signal, pregnancy number-of-elapsed-days calculating means (38) for calculating the number of elapsed days from the fetal movement detection signals, fetal movement amount measuring means (54) for measuring the fetal movement amount per unit time from fetal movement signals read out from the detected information storage means, and displaying/outputting means (60) for displaying the fetal movement amounts acquired by the fetal movement amount measuring means and arranged in order of week of pregnancy.

A fixing device for a tensioning member of a prestressed concrete may unimly act holding force for the tensioning member on the overall peripheral surface of the tensioning member mating with the wedge. The device includes a stationary grip through which the tensioning member extends, a wedge press fitted to the grip with holding the tensioning member for fixing the tensioning member relative to the grip under a given tension, and a buffer member disposed between the tensioning member and the wedge, the buffer member having both elasticity and plasticity.

A method of continuously draw-molding a fiber reinforced plastic rod formed with a spiral groove includes the steps of arranging in parallel a plurality of reinforcing fibers under tension, impregnating an unhardened thermosetting resin in the reinforcing fibers with tension being applied to the reinforcing fibers, winding a tape having a resin impregnable property and an expandible and contractible property around a fiber bundle composed of the thermosetting resin impregnated reinforcing fibers in a spiral fashion with a winding angle being substantially equal to an angle of the spiral groove with respect to an axial direction of a rod to be molded, passing the fiber bundle with the wound tape in a heating mold provided with a hole having a cross section substantially equal to that of the rod to be molded to heat and harden the thermosetting resin, and taking up the tape thereafter.
