Title: Method for controlling speed of joint type robot
Inventor: WATABE YUJI
IPC: G05B19/416
Filed: 1985-09-02
Abstract: PURPOSE:To allow a common setting system to control a joint type robot in the case of linear interpolation and joint interpolation by calculating a distance between two points, a joint angle difference and a speed and applying a joint angle displacement. CONSTITUTION:Orthogonal coordinate values at two points stored in a memory 1, between which distance is interpolated, are converted into joint coordinate values by a converting part 5. Simultaneously the distance between two points in the orthogonal coordinates is calculated by an arithmetic part 7. Then these results are inputted to an arithmetic part 11 to obtain an angle displacement vector between two points from the joint coordinate values, and a ratio of the distance to the speed stored in the memory 1 is calculated to obtain a numeric showing how the distance is divided for interpolation. Then the angle displacement vector available from the result is divided by the dividing number, which turns out to be the value showing the joint angle displacement per unit hour and is outputted to a robot servo system. Accordingly the action obtained by equally dividing the joint can be available.

Title: Manufacture of gasket
Inventor: SESHIRU ARUBAATO BEITO
IPC: F16J15/06
Filed: 1984-09-14
Abstract: A gasket of the kind comprising particles of compressed expanded graphite bonded to an apertured reinforcement plate is made by pressing the graphite particles onto the face of the plate without lateral support of those particles at the periphery of the plate, as by pressing between two compressor belts. In thus dispensing with vertical moulding elements, the method enables a more uniform density of graphite to be obtained over the surface of the plate, and yet leaves the graphite coating at the periphery acceptably uniform with the remainder. 
<??>The method is specially applicable to the manufacture of gaskets for the cylinder head of an internal combustion engine.

Abstract: PURPOSE:To increase the output capacity by uniformly distributing the welding pressure between a stator and a rotor with a cylindrical member arranged between the rotor and a spring means. CONSTITUTION:An ultrasonic motor 100 is composed of an approximately disc- shaped base 4, a stator 3 having a ring-shaped piezoelectric element 2 and an elastic body 1, a cover member 5, a rotor 6 and a cylindrical member 10 as well as a belleville spring 13 between the above elastic member 1 and a bearing 15, a side member 12, etc. Between the rotor 6 and the cylindrical member 10, a rubber sheet 14 is interposed. Between the cylindrical member 10 and the belleville spring, a rubber sheet 19 is interposed, as well. Further, on the outside circumferential edge of this cylindrical member 10 a ring-shaped projection 10a is formed, with which the rotor 6 is pressed through the rubber sheet 14. The welding pressure applied between the stator 3 and the rotor 6 is thereby so uniformly distributed along the circumferential direction of the ring-shaped projection 10a, that the natural oscillation peculiar to the rotor 6 will hardly be generated.
