摘要： PURPOSE:To produce a fibrous formed body for a fiber reinforced composite material used as the reinforcing fibers in the composite body by extruding a solvent mixed with reinforcing fibers in a plasticized state to orient the fibers in one direction and by removing the solvent. CONSTITUTION:Reinforcing fibers such as fibers of carbon, SiC, Si3N4 or l2O3 are immersed two- or three-dimensionally at random in a melt of an org. solvent leaving no residue after combustion such as resin or wax and the melt is extruded with an extruder to form a formed body contg. the reinforcing fibers oriented nearly in one direction. The formed body is inserted into a cylindrical steel body having through holes in the side, dewaxed at about 200 deg.C and fired at 800 deg.C to remove the remaining resin or wax by combustion. A fibrous formed body for a fiber reinforced composite material consisting of uniformly oriented reinforcing fibers is obtd.

摘要： PURPOSE:To restrict transmission of vibration due to the rugged surface to a car-body to improve riding comfortableness by performing sampling of vertical acceleration detection values for a given time to make Fourier transformation of these detection values, and changing control gain in an up and down direction in response to the power spectrum density obtained by the calculation. CONSTITUTION:An active type suspension is provided with a control valve A for controlling a working fluid supplied to a fluid cylinder inserted between a car-body and wheels in response to inputted command values, an upward and downward speeds calculation means C for calculating the upward and downward speeds based on output of an upward and downward acceleration detecting means B for detecting the upward and downward acceleration of the car-body, and a command value calculating means D for calculating the command value by multiplying the upward and downward speeds of the upward and downward speed calculating means C by a changeable gain, thereby controlling the control valve A. In this case, the active type suspension is provided with a Fourier transformation making means E for Fourier-transforming the detection values of the acceleration detecting means B, and changes the above gain by a gain changing means F in response to the power spectrum density near the spring resonance frequency calculated by the Fourier transformation making means E.

摘要： PURPOSE:To respond to a change of torque at a high speed, to obtain DC output free from pulsating flow and to prevent the output variation due to an environmental change such as a temp. change or rotational variation by providing a potential difference detection means and a sample holding means. CONSTITUTION:A shaft 21 to be measured has a magnetic coil 25 provided to the outside thereof so as to form a magnetic circuit wherein the shaft 21 to be measured forms a part of a magnetic path. Further, by detecting the magnetostriction component passing through the shaft 21 to be measured, the torque applied to the shaft 21 to be measured is detected. The potential difference corresponding to the magnetostriction component is detected by a potential difference detection means 30 and the potential difference value is held as a sample in predetermined timing by a sample holding means 40 to detect the torque applied to the shaft 21 to be measured. By this method, a response speed is increased and pulsating flow is eliminated and the output variation due to an environmental change is prevented.
