Patent EP-0487737-A1 (EP)
Inventor: TORII NOBUTOSHI
IPC: B23K9/127
Filed: 1991-05-28
Abstract: A method of controlling the operations of a galvanometer for a scanner for moving sweepingly a laser beam in conjunction with a rocking mirror of an arc sensor for searching a welding line of a welding robot. A memory (43) stores waveform data of a galvanometer driving command current obtained by the combination of a constant speed command current and an acceleration/deceleration command current. An address circuit (42) causes the memory (43) to output the waveform data at predetermined intervals, a D/A converter (44) converts the data in to the analogue value on receiving it from the memory (43), and a drive circuit (45) drives the galvanometer (22). The galvanometer (22) rocks the rocking mirror to search the welding line. For a successful search, the galvanometer, in accordance with the waveforms of the galvanometer driving command current, is operated at a constant angular velocity at points other than bent points of deflection angles, or is operated at a constant angular acceleration at the bent points of the deflection angles. Accordingly, deflection angles are accurately controlled over all the operation angles. Furthermore, at bent points, changes in directions of the deflection angles can be performed in very small periods of time. Further, overshoots, which used to occur at the bent points of triangular waveforms, do not occur. As a result, measuring for searching the welding lines by the laser beam scan can be performed most effectively and efficiently.

Abstract: An arc plasma torch (10) includes a moveable cathode (14) and a fixed anode (16) which are automatically separated by the buildup of gas pressure within the torch after a current flow is established between the cathode (14) and the anode (16). The gas pressure draws a nontransferred pilot arc to produce a plasma jet. The torch (10) is thus contact started, not through contact with an external workpiece, but through internal contact of the cathode and anode. Once the pilot arc is drawn, the torch may be used in the nontransferred mode, or the arc may be easily transferred to a workpiece. In a preferred embodiment, the cathode (14) has a piston part (48) which slidingly moves within a cylinder (50) when sufficient gas pressure is supplied. In another embodiment, the torch is a hand-held unit and permits control of current and gas flow with a single control.

Abstract: A scroll type compressor with a variable displacement mechanism is disclosed and includes a housing having an inlet port and an outlet port. A variable displacement mechanism controls an opening and closing of a communication path communicating the suction chamber to the pair of intermediately located sealed spaces. The variable displacement mechanism includes a cylinder a part of which is defined within the communication path, a piston member which is slidably disposed within the cylinder and a conduit which permanently links the discharge chamber to the cylinder so as to introduce the discharge pressure to one end surface of the cylinder opposite to the part of cylinder. A location of the piston member within the cylinder is varied in response to changes in the discharge pressure so as to control the opening and closing of the communication path, thereby varying the displacement of the compressor.

The fiber-reinforced composite according to the present invention includes: a base formed of carbon-fiber reinforced composites having a good mechanical strength characteristic and good fracture toughness; and a surface portion covering the base and formed of ceramic-fiber reinforced composites having good oxidation-resistance, wherein the carbon content rate of the base decreases almost successively from a central portion of the base to an interface portion of the base and the surface portion. This results in the fiber-reinforced composite which has good oxidation-resistance, a good mechanical strength characteristic and good fracture toughness even at high temperatures not lower than 1500°C and in which an abrupt change in respective thermal expansion coefficients of the base and the surface portion in the interface therebetween is reduced by its gradient composition.

Abstract: Conventional Boolean Logic Control is augmented to provide enhanced diagnostics, monitoring, and fail safe operation for dynamic systems having distributed discrete-valued sensors and actuators. A decentralized model of a controlled system defines behavior and timing models for both sensors and actuators, termed Control Elements (CEs). Each CE has a first model for transition from state 0 to 1, and a second model for transition from state 1 to 0. Each behavioral model is defined by an Event Signature comprising a sequence of state changes in neighboring CEs. A continuous evaluation of event signatures is performed to compute a probability that a given CE will change state. An Expectation Function is used to check and enforce the correct behavior of a CE. A statistical temporal model predicts delays in the states of a CE as a function of its previous and current delays. The distributed behavior and on-line timing models are used to detect and diagnose incorrect behavior and failures of decentralized sensors and actuators.

The lower dielectric layer (48) overlies the lower common electrode layer (42) and bottom substrate layer (40). The middle light-energy generating layer (52) is deposited over the lower dielectric layer (48). The upper dielectric layer (50) is deposited over the middle light-energy generating layer (52). A light emitting face (54) on a front edge of the EL stack (46) is disposed at an angle relative to a street (56) on the front edge portion of the substrate layer (40) that is greater than ninety degrees. The angle selected should be sufficiently greater than ninety degrees relative to the substrate layer street (56) so that a divergent zone of light (58) emitted by the face (54) is not obstructed by the street (56). A focussing lens (60) is located at a position spaced in front of the inclined light emitting face (54) of the TFEL edge emitter structure (38) where the lens (60) will intercept and intensify a zone of light (58) emerging from the inclined face (54).

Abstract: An infusion device which permits transcutaneous access to an implanted catheter for use in introducing an external filament such as a optical fiber, external catheter, guide wire or rigid needle. In accordance with this invention the device includes a valve assembly (34) including a first valve element (36) defining an aperture (38) with a sealing member (40) which is normally to engage and seal against the aperture. The sealing element is made from a hard material such as a metal. Upon introduction of a rigid external introducer such as a needle, the needle directly contacts the sealing member plug (92) unsealing it from the valve element aperture which then closes against the external element. The device enables repeated access using a sharp introduced element such as a needle without it contacting soft sealing elements which could be degraded by such repeated access.
