Title: Focus error detection
Inventor: HAMAGUCHI SHINGO
IPC: G11B7/135
Filed: 1988-12-12
Abstract: PURPOSE:To output a focus error signal of high precision which is not affected by attaching positions of photodetectors, the inclination of beam, or the like to improve the reliability by outputting the focus error signal based on the output corresponding to the quantity of received light on the whole of photodetectors. CONSTITUTION:The linearly polarized reflected light which is parallel rays, convergent light. or divergent light in accordance with positions of an optical disk 25 and an objective lens 24 is separated to a first reflected beam 31 and a transmitted beam 32 by a half mirror 30. A polarizing beam splitter 33 has dependency upon the angle, and a part of the beam 32 is transmitted through the polarizing beam splitter 33 when it is convergent light or divergent light. First and second photodetectors 36 and 37 to receive beams 31 and 34 are provided, and a third photodetector 38 is provided which does not receive the transmitted light from the plitter 33 at the time, when the beam 32 is convergent light, but receives the transmitted light of divergent light. An operation circuit 45 outputs a positive or negative focus error signal in accordance with the output of the photodetector 38 based on outputs of photodetectors 36 and 37. Thus, the focus error signal of high precision is outputted which is not affected by attaching positions of photodetectors, the inclination of the beam, or the like.

Title: Fine wire feeding method
Inventor: TANAKA MASAYUKI
IPC: B65H59/06
Filed: 1986-12-24
Abstract: PURPOSE:To prevent entwinement and entanglement of a fine wire and to enable the smooth feed of a fine wire, by a method wherein a bobbin around which the fine wire is wound is immersed in liquid, and by pulling the fine wire in the direction of the axis of the bobbin, the fine wire is unwound. CONSTITUTION:When a metallic wire 2 is pulled upward, the metallic wire 2 wound around a bobbin 1 is unwound as it is disentangled. In this case, since the metallic wire 2 is braked by means of viscosity of pure water 12 and is kept in a state where proper tension is normally applied, entangling of the metallic wire 2, equivalent to some full rounds around the bobbin, at one time or drop of the metallic wire from the bobbin 1 is prevented from occurring. Thus, since entwinement and entanglement are difficult to occur the metallic wire 2 and besides so high tension is not exerted on the metallic wire 2 even if the unwinding speed of the metallic wire 2 is increased, the smooth feed of the metallic wire is practicable at any unwinding speed throughout a range of from a low speed to a high speed.

Filed: 1987-12-14
Abstract: PURPOSE:To ensure the highly efficient actions of an industrial joint type robot by deciding the highest working speed, the acceleration and the servo gain of the robot from the tables and the storage value which are previously and experimentally decided and actuating the robot under these working conditions. CONSTITUTION:The tables containing the acceleration and the maximum speed of both joint drive motors MTHETA and MU is previously stored in a ROM 24 for each range of the load weight and also in response to the working ranges of both motors. Furthermore the ROM 24 stores the servo gain decided previously and properly in response to the load inertia. Then the acceleration values, the maximum speed values and the servo gains stored in those tables are recorded to a RAM 26 using a teaching control panel 28. Thus those values are selected out of the tables under the control of a CPU 22 or out of the stored servo gains and set at an axis control unit 34 via a bus 23. In such a way, a robot is operated with high efficiency.

Abstract: PROBLEM TO BE SOLVED: To prevent the controlled variable of a damping force calculated through skyhook control from becoming an error as the relative speeds of upper and lower springs, estimated from the acceleration of the upper spring during a turn, become erroneous values. SOLUTION: This suspension control device, which has a skyhook control means M2 for controlling the damping force of a suspension mechanism M5 based on the theory of skyhook by estimating the relative speeds of upper and lower spring members from the acceleration of the upper spring detected by an acceleration detection means M1 and by using the relative speeds and the speed of the upper spring which is determined from the acceleration of the upper spring, has a steering angle detection means M3 for detecting steering angle and a controlled variable correction means M4 for correcting, during a turn and from the steering angle detected, the controlled variable of the damping force that is based on the theory of skyhook.  Therefore even if the controlled variable of the damping force becomes an error during a turn, damping force control can be prevented from becoming erroneous during the turn, since the controlled variable of the damping force is corrected.
