Patent EP-0276156-A2 (EP)
Inventor: OHTAKA YOSHIMITSU
IPC: B41J2/16
Filed: 1988-01-21
Abstract: A nozzle plate (5) in which a nozzle (4) through which fluid can pass is formed is prepared, and an insulator layer (14) is located in layer on the nozzle plate (5) except a location of the nozzle (4). An electrode plate (11) is provided so as to cover the insulator layer (14), and a valve beam (19) made of a conductive substance is located in an opposing relationship to the nozzle plate (5). A valve for opening and closing said nozzle (4) is formed at a yieldable portion of the valve beam (19) opposing to the nozzle (4). Upon energization of the electrode plate (11) and the valve beam (19) of a valve element thus produced, the valve is attracted toward the electrode plate (11) to open or close the valve. Binary control of the valve to fully open or fully close the nozzle and infinite control of the valve to infinitely open or close the nozzle can be readily attained in the valve element.

Abstract: Framework for supporting surgical instruments such as retractors at a surgical wound includes a pair of rigid frames (60a and 60b) that together form a rectangular retractor ring (60) from which surgical instruments such as retractors can be suspended above an operating table (18), thus eliminating the need for surgical assistants to hold instruments by hand. Each of the rigid frames (60a and 60b) has a cross arm (66a and 66b) that is releasably and rotatably attached to a crosspiece (27) that extends across the operating table (18). This rotatable attachment enables either of the frames (60a,60b) to be pivotably retracted from time to time to afford better access to the wound. While one of the rigid frames (60a and 60b) is so retracted, the other can continue to support surgical instruments. The framework is especially useful in back surgery in combination with a kneeling attachment (20) including a platform (22) on which a patient (21) kneels.

Abstract: An earth boring apparatus has a pneumatically oper­ated earth boring tool, a flexible conduit or drill pipe connected to the tool and to a source of pneumatic fluid. The tool has an earth boring member and a reciprocally mov­able hammer positioned in the tool to apply a percussive force. A valve assembly in the flexible conduit or drill pipe substantially adjacent to the tool between the tool and the source of pneumatic fluid controls the flow of pneumatic fluid to the tool in response to the pressure of pneumatic fluid in the flexible conduit or drill pipe permitting the valve to be opened to permit flow of pneumatic fluid to the tool at a predetermined operating pressure to transmit an initial pulse of pneumatic fluid to initiate operation of the hammer. The valve is kept open at a lower pressure than that required to open it. One form of the valve is a press­ure operated valve, spring-loaded toward closed position, opened at a first predetermined pneumatic pressure permit­ting flow to said tool and closed at a second, substantially lower, pneumatic pressure. Another form of the valve in­cludes a valve, spring-loaded toward closed position, which opens in response to pneumatic conduit pressure, and spring loaded ball detents or a pneumatic pressure operated latch to secure the valve in an open position. The latch and valve are operated to closed position at a lower pressure.

Abstract: An AGC for a laser amplifier uses a control tone modulated onto the optical signals. During use the modulation on the optical signals is superimposed on the drive current for the laser. The AGC derives a control signal by detecting the modulation in the drive current, multiplying it by the drive current. The drive current for the laser is adjusted to keep the control signal constant. In a preferred embodiment a low level sensor detects when the control tone falls below a threshold level and switches the circuit to a default configuration. The default configuration provides a distress signal to indicate a fault and to identify the affected amplifier. This preferred embodiment is particularly suitable for submarine telecommunications cable which include a plurality of inaccessible amplifiers.

Abstract: The invention relates to a protecting device for a synchronous motor, for detecting an asynchronous state, caused by a mains disturbance, in which a susceptance (1 DIVIDED X) is determined from the stator current (I) and stator voltage (U), which susceptance activates a trip if a protection characteristic (s;s';t), defined by an adjustable response value ((1 DIVIDED X)e), is exceeded. If the synchronous motor is connected to an approximately constant mains voltage, then the detection of the reactive component (IB) of the stator current (I) or the reactive component (PB) of the power (P) is sufficient. With suitable adjustment of the protecting device with respect to asynchronism and lose of synchronisation as a consequence of mains disturbances, it is also possible to detect faulty under-excitation or loss of excitation of the synchronous motor. <IMAGE>
