Abstract: The invention involves non-contact sensing of a selected location on a substrate at which material is to be deposited, and positioning of a material depositing tip a preferred distance from this location on the substrate according to such sensing and in preparation for the depositing. Preferably, the tip is advanced to a preferred spacing between it and the substrate, without overshooting the spacing and without contacting the substrate, in preparation for depositing.

Abstract: An acceleration regulator in the driving system of an automotive vehicle comprising an element for transmitting displacement comprising a first portion and a second portion; a differential mechanism having a first input terminal connected to the first portion of the element, a second input terminal, an an output terminal connected to the second portion of the element, and being so arranged that the amount of operation applied through the first portion of the element to the first input terminal is modulated differentially by the piston of the second input terminal so that the modulated amount of operation is taken out at the output terminal; and a fixing mechanism for variably fixing the position of the second input terminal of the differential mechanism, the fixing mechanism being so arranged that when the hydraulic pressure in the hydraulic circuit of the driving system rises to a preset level slightly lower than the relief pressure of the circuit, the second input terminal of the differential mechanism is m

Abstract: Pressures applied to a component for pickup and placement thereof are each selectable, according to introduction of gas under pressure into a piston and cylinder configuration defined by a tool, such as a vacuum spindle, telescopically supported in a tool holder. An actuator with closed loop velocity and displacement control moves the tool holder to and fro along a longitudinal axis according to a known programmable controller. Thus, compression of the gas and relative displacement between the tool and holder allows controlled pick and place pressures to be varied and monitored programmably. The pressurized gas also acts to prevent dirt contamination of the bearing surface between the tool and holder and consequent impairment of telescoping and rotational movements therebetween.

Abstract: A pedestal carrying a television camera and its accessories has constant-torque springs which are housed in a detachable housing. The output shaft of each constant-torque spring is made responsive to the weight of the camera and its accessories, and is connected via a reduction mechanism with a mechanism for winding up a line such as wire.

Abstract: Disease causing material obtained by cultivation of Phomopsis cirsii or Septoria cirsii can be used for controlling weeds such as compositae.

Abstract: A spectrophotometer provided with a plurality of integrating spheres of different types which can be selectively and exchangeably used in accordance with the type of a sample to be measured and the purpose of the measurement.

Abstract: The color filter of this invention comprises a transparent substrate, a porous activated film layer formed on the substrate and made of activated alumina or activated silica or a mixture thereof, a colored area or a pattern formed by the dye fixed in the minute pores of the activated film layer, and a coating layer sealingly closing the upper portions of the minute pores of said activated film layer. This color filter is relatively simple and easy to manufacture, superior in resistivity to heat, water, chemicals, solvents, etc. and suitable for use as a color filter in various display devices, particularly liquid crystal display devices.

Abstract: Routing a circuit board from the bottom side allows router access to areas not generally accessible from the top side, such as board areas which are overhung by electrical connector "headers", as well as variable potentiometer and capacitor controls which may not be easily accessible from the top side. One embodiment combines such routing with shearing to merge their respective advantages.

Abstract: Treatment of colored cellulose fiber fabrics for at least fifteen minutes with an aqueous solution of cellulase containing at least about 250 CMC units per liter under pH conditions conducive to high activity for the cellulase clarifies the color.

Abstract: In separating pecan meats according to weight, removal of acceptable pecans along with lighter, unacceptable pecans is obviated by avoiding the increased vacuum on acceptable pecans which occurs when an unacceptable pecan restricts a vacuum duct used for such separation. In one embodiment, positive and negative fluid pressures are utilized in concert to avoid such a restriction.

Abstract: Electronic components, such as resistors with bodies of different lengths and axially protruding leads, are fed along a feed path and between a pair of rotating members. Each rotating member has fingers that are flexed away from the feed path for reception of the component bodies between cooperating fingers of the rotating members, after which these fingers close onto the bodies to center them on the feed path.An opposed pair of the flexible fingers, one from each rotating member, retain each component in a centered condition along the feed path until corresponding leads of consecutive components are taped together at a subsequent taping station to form a ladder-like belt of components.

Abstract: In accordance with one embodiment of the invention, solder masking material is pressurized by means of a fluid pump to approximately 250 psi and high speed valve is used to turn the flow on and off rapidly in order that small "shots" of fluid are propelled from a tip, through the air, to selected portions of a circuit board. The selected areas of the circuit board to be masked are situated oppositely from the tip , as by a XY positioning system for the tip and/or the circuit board. The drops of masking material, which form upon impinging of the shots onto the circuit board, may be varied in volume and diameter. Where needed, a continuous bead of masking material may be formed on the circuit board by spacing the dots sufficiently close together.

Abstract: In a wire saw drive apparatus having a carriage, a wire drive pulley mounted on the carriage, pulley drive means for rotating the wire drive pulley to drive an endless cutting wire, a pair of adjust pulleys for guiding a tensile side and a loose side of the cutting wire, and carriage drive means for moving the carriage and maintaining the cutting wire under a desired tension, the improvement comprises elastic means mounted between an adjust pulley supporting body for guiding at least the tensile side of the cutting wire and the carriage, for receiving a force applied from the cutting wire to the adjust pulley, and a guide pulley mounted on the carriage near the adjust pulley for guiding the tensile side of the cutting wire, for guiding the cutting wire into S shape fashion in cooperation with the adjust pulley.

Abstract: A trocar type biopsy instrument characterized by:(a) structure for locking the cannula and stylet of the instrument together so as to allow these components to penetrate soft body jointly as a unitary whole;(b) structure for retracting the cannula rearward along the stylet far enough to expose the specimen notch, and for returning the cannula along the stylet to its original advanced position covering the specimen notch;(c) removable stylet retaining structure so that the stylet may be removed while the cannula remains locked in its advanced position.The instrument of the present invention facilitates the manipulative efforts required for performing soft tissue biopsy procedures.

Abstract: In a preferred embodiment, the supply tape is stepped to present each pocket at a pick-up area for removal of a component. Each pocket is opened in turn during the indexing step that positions it at the pick-up area, and a shutter is moved over the pick-up area prior to tape movement so that the pocket is covered by a shutter during the tape movement and peeling of the cover from the substrate. After each indexing step, the shutter is moved away from the pick-up area in order to provide access to the component in the opened pocket.

Abstract: A rotary torso exercise machine, including an upper torso engagement means comprising a back rest, a right side bar and a left side bar.
