Abstract: A digital control provides adaptive feedforward torque control for a robot [Figs. 1-3] having a plurality of arm joints. An electric motor (20) drives each of the robot arm joints and a power amplifier [Fig. 1 (22)] supplies drive current to each motor under controlled operation. Each joint motor has feedback control loop means including position (PFB) and velocity control loops (VFB) driving a torque control loop (8) in accordance with position commands (PCOM) to generate motor commands for controlling the associated power amplifier. The motion of said joint motor is sent to generate position and velocity feedback signals respectively for combination with the position and velocity commands to generate an error signal (TQCOM) as a torque command for each of the torque control loops from the corresponding position and velocity control loops. Load force is sensed (19) at the endmost robot joint. A feedback signal [Fig. 1 (21)] representative of the joint motor drive current is combined [Fig. 2 (168)] with the torque command to generate a torque error signal in each torque control loop.

Abstract: The invention relates to a placement head assembly (100) for use in an electrical component placement machine and to a method of placing components on a circuit board. A hollow main shaft (34) has a carriage assembly (124, 126) disposed thereabouts. Rollers (144, 146, 148, 150) on the carriage assembly engage the shaft outer surface (34), providing for axial movement along the shaft. A vacuum support shaft (106) in coaxial alignment within the main shaft telescopes down­wards to pickup and retain a component for subsequent align­ment in a plane substantially normal to the longitudinal shaft axis. 
     The carriage assembly carries actuator means (152, 154, 156, 158, 136, 160, 162) urging the carriage assembly into axial movement in response to fluid pressure differentials. Tweezer means are pendantly disposed in quadrature from pivot points about the shaft. Jaws at the lower ends of the tweezer means are thereby positioned circumferentially about the component when suspended from the vacuum support. 
     Downward movement of the carriage assembly causes roller surfaces thereon to engage corresponding surfaces of upper ends of the tweezer means, thereby forcing these upper ends radially outwards. Pivoting action of the tweezer means correspondingly forces the jaws radially inwards from four quadrants into contact with the component, thereby aligning it for subsequent board placement. 
     In one embodiment, the actuator means includes a piston-­cylinder assembly. Pressure differential across the piston causes downward movement of the carriage assembly. Reverse pressure differential urges the carriage assembly upward. Spring-loaded return of the jaws to the radially outwards position prior to contact with the component is thereby facilitated.

Abstract: The counter has a rotating element with an optical reflectivity which periodically changes along its circumference or a changing optical transparency. A light beam (LE) is directed onto the rotating element and the reflected or transmitted light beam (LR) is analysed with respect to the periodicity of the light intensity. From the period determined, the speed of rotation of the rotating element is determined. To increase the accuracy and the resolving capability of the method, a light beam (LE) consisting of coherent light is used which can be generated, for example, by a laser semiconductor diode (2). The reflected light beam (LR) is received via a photoreceiver (5) and supplied to an evaluating device (6-7-8).

     An optical pickup device comprises an optical element wherein a grating which grating pitch is approximately equal to the wavelength of an incident light, is formed on a transparent base. An optical pickup device comprises a polarized light detecting unit provided with a diffraction grating which grating pitch is approximately equal to the wavelength of an incident light, that is formed on a transparent substrate, and that splits the incident light into two polarized lights having mutually orthogonal polarizations; a first photodetector that is mounted integrally and virtually in parallel with the substrate, and that receives a zeroth-order diffracted light produced by the diffraction grating; and a second photodetector that is located in the same plane as the first photodetector and mounted integrally with the first photodetector and the substrate, and that receives a first-order diffracted light produced by the diffraction grating. 
     As a result, a simple and inexpensive optical element may be fabricated, and a compact and light optical pickup device may be designed. Furthermore, the access to a magneto-optical recording medium may be performed accurately, and recording signals of high quality may be   obtained.

Abstract: A seismic pulse generator comprises a body 1 having an internal gas-pressurizable first chamber 2 adjoining a second chamber 6 for containing a fluid. A flap valve member 21 is rotatable about a pivot axis for closing a bore 24 communicating with the first chamber. A latch 22 releasably retains the flap valve member in the closed position and a gas operated piston 13 slidably moves within an associated cylinder 12. When the first chamber 2 is pressurised with gas and the flap valve member 21 is released from its closed position to uncover the bore 24, the piston 13 moves to cause communication between the chambers 2,6 and generation of a shock wave in the second chamber. The second chamber has outlet means 7 to permit a pulse of energy to be transmitted from the second chamber in response to the shock wave generated in the second chamber. The flap valve member can be arranged to be openable such that full bore opening of the bore 24, loss of gas pressure from bore 24, and the response of piston 13 to cause communication between the chambers can all be achieved very rapidly.

Abstract: Drive means for recording and/or reproducing apparatus includes a first gear train (26, 45, 46 or 47, 3 a  or 4 a ) causes a supply or take-up reel table (3, 4) to rotate at a first speed, and a second gear train (26, 40, 46, 3 a ) which causes the supply or take-up reel table to rotate at a second speed higher than the first speed. By selecting one of these gear trains, the apparatus selectively operates in a FF/REW mode or a high-speed FF/REW mode. In the FF/REW mode, the tape forwarding or rewinding is performed in a tape loaded condition in which tape is arranged in the usual tape travelling path. In the high-speed FF/REW mode, it is performed in a tape unloaded condition in which the tape is arranged at a location other than in the tape travelling path, or is housed within a tape cassette. The system has a torque limiter (17, 27) between a driving source (5) and the first or second gear train. When the apparatus operates in a forward or reverse reproduction mode, the torque limiter acts on the first gear train so as to decrease the rotation speed of the supply or take-up reel table depending upon a load applied to the first gear train.
