Filed: 1984-05-31
Abstract: PURPOSE:To record on a continuous moving body excellently by opening and closing a microshutter which has normally on type liquid crystals in a dot array at frequencies lower and higher than a cross frequency based upon the anisotropy of a liquid crystal agent as zero. CONSTITUTION:A data signal from a recording control circuit which is not shown in a figure is inputted to a liquid-crystal optical shutter 13 to open and close the mu shutter 15. When it is open, light is passed to form an image on an unshown photosensitive drum to the same size with the mu shutter 15. The liquid crystal shutter 13 is formed by arraying mu shutters zigzag in two lines. The photosensitive drum rotates at a speed (v) as shown by an arrow 16. The length of a mu shutter 15 in the direction of the arrow 16 is L, length perpendicular to the arrow is l, and pitch is (p). Then, the advance in one write period TW, vTW is equalized to L. When a mu shutter is opened for a time TL, an area L+vTL is exposed. The length L of the mu shutter 15 is set less than v(2TW-TL) to obtain black dots having no density difference.

Title: Acoustic device
Inventor: YONEYAMA MASAHIDE
IPC: H04R1/32
Filed: 1984-05-31
Abstract: PURPOSE:To prevent noise from spreading to the neighborhood and to improve acoustic effect to an objective person by providing an acoustooptic transducer which reproduces an original audible tone by the nonlinearity of air on a railroad crossing or pedestrian crossing, and radiating the acoustic wave from the electroacoustic transducer to passersby. CONSTITUTION:Nonlinear parametric speakers 101-106 which have very narrow directivity are used as alarms of a railroad crossing and installed over a road 11. In this case, plural speakers may be fitted in parallel so as to generate an acoustic wave in the same direction and widen the service area. In general, an alarm installed on a railroad crossing is for giving a warning to persons and bicyclists walking or riding on the road ahead, and the conventional alarm has wide directivity, so an acoustic wave is radiated in every direction, causing a noise pollution to a neighboring residential area, specially, at night. On the other hand, when those nonlinear parametric speakers are used instead of the alarm, only persons and car drivers walking and driving on the road ahead are given a warming and no noise disturbs the neighborhood.

Abstract: PURPOSE:To erase a surplus rotational inertia of a rotating body, and to obtain a complete inertial running state, by providing a damping means for applying deceleration torque to the rotating body, detecting torque of the rotating body, determining torque to be applied at that time, and controlling the damping means. CONSTITUTION:A controlling disk 28 detects torque applied to drums 12, 14 due to a fact that a tire of a test vehicle contacts, and also, compares a moment of inertia of the test vehicle and the minimum moment of inertia Ic, Io, and controls torque applied to the controlling disk 28, in accordance with its difference. The torque to the controlling disk 28 is applied to a brake 32 which is provided on an arm 30, by supplying hydraulic pressure through a servo-valve. The applied torque is detected by a load cell 40, amplified by an amplifier 42, and thereafter, multiplied by a distance R by a force/torque transducer 44, and the torque of a shaft 34, and subsequently, torque which is applied to the drums 12, 14 are calculated.

Filed: 1995-04-13
Abstract: PURPOSE: To provide a cut through connector which can correctly set the center of an insulated cable to the center of an electrode blade, and besides the electrode blade of which is hardly bent. CONSTITUTION: An electrode blade 5A has a shape of a circular edge with a radius of curvature larger than the radius of circumference of a cable sheath 6 viewed from the longitudinal direction of the cable and a width D of edge not less than the diameter of a conductor 7, and constitutes the form of a cross section where the center in width direction of the blade is thin and both sides are thick. Since the radius R of curvature on the circular arc of the edge of an electrode blade 5A is larger than the radius of circumference of the sheath 6, even if the center of the insulated cable 3 and the center of the electrode blade 5A are slipped a little, the insulated cable 3 is lead automatically to the proper position by fastening a connector. Since the center of the electrode blade 5A is thin, the force of cutting through the sheath 5 gets off small.  Since both sides are thick, the electrode blade 5A is hardly bent.
