Abstract: Provided is a liquid ejection apparatus, liquid ejection method, dispensing apparatus, and compound introduction apparatus capable of inhibiting contamination of a liquid after being ejected. The liquid ejection apparatus has an ejection unit having an ejection part and an ejection energy generation element that ejects a liquid from the ejection part by using a principle of inkjet ejection into an internal space in a storage part capable of storing the ejected liquid. When ejecting the liquid, the ejection unit covers an opening portion of the storage part to thereby screen the internal space in the storage part from an external space.

Abstract: An electric leakage detection method includes: measuring a set of a first voltage and total voltage times to be recorded in a memory by the control apparatus in a state that one of first and second switches is closed and another of the first and second switches is opened; measuring, by the voltage detector, at least one second voltage corresponds to the total voltage whose difference from any one of the total voltages recorded in the memory is equal to or less than a voltage threshold value; computing a total insulation resistance between the storage battery group and the ground by using the total voltage, the first voltage, and the second voltage; and determining presence of electric leakage when a value of the total insulation resistance is equal to or less than an electric leakage threshold value.

Abstract: A method of manufacturing a double-raschel knitted fabric tube W for artificial blood vessels is provided, which is configured of N cocoon filaments each formed of paired core parts formed of fibroin and a skin part surrounding the core parts and formed of sericin, separating the paired core parts with the sericin partially removed and partially left to form 2N plies of the fibroin with a skin core structure to obtain a sericin-coated silk thread configured of the 2N plies of fibroin having the skin core structure, then subjecting the sericin-coated silk thread to a first twist to produce a first-twist silk thread, further combining a plurality of the first-twist silk threads together and subjecting the combined first-twist silk threads to a second twist to produce an organzine silk thread, and then further knitting a tube shape by using the organzine silk thread T as a knitting thread Y.

Abstract: The present invention has an display section for displaying an operation state of a program to a user in a time series manner based on program execution history information, an input section for allowing the user to designate a portion of a defect in the displayed operation sate, and an operation analysis section for analyzing a cause of the defect from the portion of the defect pointed out from the user by the input section and from the operation state of the program, and for specifying a solution for solving the cause of the defect. The operation analysis section regenerates the operation state on which the specified solution is reflected, and the display section displays the cause of the defect, the solution and the regenerated operation state to the user.

Abstract: An improved control system with an embedded microcomputer is described which makes it possible to facilitate procedures for maintenance and modification of the specification and effectively use existing software resources by means of a configurable real-time OS. The real-time OS comprises an operation descriptor for storing control data for controlling the plurality of the tasks respectively, a kernel for controlling the operation of the control system with reference to the operation descriptor, and an interface provided for receiving data for modification of the control system and rewriting said operation descriptor in order to update said real-time OS.

Abstract: The engines which have output shafts connected to traction speed change mechanisms via freewheel clutches are decelerated or accelerated at a desired speed change ratio and then rotate and drive a collector gear and a main rotor shaft. A part of output torque of the engines is diverted into gears to drive and rotate accessories and a tail rotor. Such an arrangement is useful for a power transmission for a helicopter in that it enables the speed of rotation of the main rotor to be varied while the speed of rotation of the engines is kept constant.

Abstract: Electrode for tungsten inert gas welding having a body of a circular cross-section with a frustoconical tip end having a cone angle less than 120.degree.. The electrode is formed with an axially extending cylindrical recess at the tip end to leave an annular area. The configuration of the electrode is effective to decrease the intensity of the arc force so that the welding process can be performed with a heavy current and high speed.
