摘要： PURPOSE:To provide a monitor function and to switch optical paths without moving an optical path switching part by utilizing the polarizing and separating operation of polarizing prisms, photodetecting a half of input light by a light receiving element and outputting the remaining half as output light directly. CONSTITUTION:The 1st and 2nd polarizing prisms 16a and 16b are arranged their polarizing films opposite each other, and the 1st polarizing prism 16a is used for photodetection and the 2nd polarizing prism 16b is used for optical transmission. The polarizing and separating operation of the polarizing prism 16 utilizes the difference in reflection coefficient between P polarized light and S polarized light at a Brewster angle. A half of the input light is therefore inputted to the light receiving element at all times and the remaining half becomes the output light, and when an LD is used as the light emitting element, the majority of the sent light becomes the output light at the time of optical transmission, but when an LED is used, the half of the sent light becomes the output light and a movable part functions only to cut of the light signal. Consequently, the monitoring function is provided, the optical axes of a movable block and a receptacle which switch optical axes are easily adjusted, and the cost is reduced.

摘要： PURPOSE:To simplify system construction by uniting and assembling an optical switch, photo/electric conversion part and electro/optic conversion part so that a light signal can be directly processed to an electric signal or the electric signal to the light signal by uniting and assembling an optical switch, photo/electric conversion part and electro/optic conversion part. CONSTITUTION:An element module 17 including a light receiving element 16 and a condenser lens 2b is disposed in one of the optical paths changed over from a receptacle 3a for incidence to a receptacle 3d for emission by reflection mirrors 6a, 6b and an element module 19 including a light emitting element 18 and a collimate lens 2c is disposed in the other. The optical switch, the photo/electric conversion part and the electro/optic conversion part are, therefore, directly connectable without using two optical fibers with optical connectors. The cost in the LAN system is thereby reduced.

摘要： PURPOSE:To reduce an insensitive range due to friction by making the controlling force of an actuator actuating a moving mass to be a sum of a controlling force proportionate to the vibratory speed of a vibratory body and a controlling force equivalent to the frictional force of a movable mass. CONSTITUTION:When a vibratory body 1 is excited by an external force, the vibratory speed of the vibratory body 1 as sensed by an accelerometer 7 is sent to an actuator 3 through an integrator 8a, a totalizer 8d and a power amplifier 8e. The relative speed between the vibratory body 1 and a movable mass 4 is detected by a relative speedometer 9 and is added to the vibratory speed of the vibratory body 1 by the totalizer 8d after going through a polarimeter 8b and a vibration generator 8c. Since the output by the voltage generator 8c causes the actuator 3 to generate a force negating the frictional force, an insensitive range due to the frictional force is solved.

摘要： PURPOSE:To obtain a stable control in the vertical vibration of a vibrating body by providing the vibrating body with a movable mass via a spring and an actuator and supporting the weight of the movable mass by the actuator for selecting the spring constant of the spring optionally. CONSTITUTION:Controller 8 receives the acceleration signal of an acceleration meter 7, and outputs a signal to generate a force to offset a control force proportional to the vibrating speed of a vibrating body and the weight of a movable mass 4 in an actuator 3. This construction permits to obtain a stable control for vibration since the weight of the movable mass 4 is unnecessary to be supported by a spring 2 and the spring constant of the spring 2 can be optionally selected without reference to the weight of the movable mass 4.

摘要： PURPOSE:To control the vibration, by providing a detector for the vibration quantity generated in a vibrating body such as a high level road and giving the output of an actuator, which generates a controlling force corresponding to the vibration quantity, to the vibrating body through a two-stage cylinder mechanism and a connecting member. CONSTITUTION:A beam 6 has both ends supported on supporting bases 7, and a pair of arms 8 are attached near both ends of the beam 6, and a moment is generated by the force applied to tips of arms 8 in the longitudinal direction of the beam 6. The output shaft of an oil pressure actuator 10 is connected to a cylinder mechanism 21 consisting of a cylinder 17 and a piston 18, and further, the output shaft of the actuator 10 is connected to a tendon 9 by driving of a cylinder mechanism 22 consisting of a cylinder 19 and a piston 20. A sensor 11 attached to the center of the beam 6 detects the oscillation quantity to drive the actuator 10 through a filter 12, a controller 13, and an oil pressure driving device 14. The force is doubled in this manner to give the force, which acts against the displacement and the speed of the vibration, to the beam 6, thus controlling the vibration.

CONSTITUTION:A pier 1 is fixed onto bases, which are buried deeply in the ground, and consists of a beam part 3 and leg parts 4. A supporting frame 9 supports the beam part 3 in the approximate center of the beam part 3 and has beams 10, which extend obliquely toward leg parts 4 from the supporting point, and vertical supporting legs, which have one ends fixed onto bases 2 and the other ends connected to beams 10, and is provided with actuators 12 in middle points of legs 11. The actuator 12 consists of, for example, a motor and is a mechanism to move vertically the frame 9. The acceleration of the vibration is detected by a sensor 13 provided in the beam part 3 to give a controlling force corresponding to the velocity of the vibration to actuators 12 through a filter 14, a controller 15, and a power amplifier 16.
