Abstract: There is provided a drug which exhibits preventive and therapeutic effects on virus infectious diseases by inhibiting virus-derived protease on the basis of various physiological activity actions of an active sulfur compound(s) which exists in living organisms.

Abstract: A display control device includes one or more processors configured to: acquire information regarding a plurality of driving evaluation items set in advance; count, as the number of times of measurement, the number of times that at least one of a vehicle state and a driving state meets each of the driving evaluation items while a driver is driving a vehicle; display the driving evaluation items in a display region in a vehicle cabin; and visually display information relating to the remaining number of times that is a difference between the permissible number of times set for each of the driving evaluation items and the number of times of measurement.

Abstract: The present invention is a biomarker for diagnosing infectious disease wherein the biomarker is a sulfur metabolite, and the sulfur metabolite may be a sulfur metabolite present in exhaled air, and the sulfur metabolite can be detected from exhaled air condensate. The biomarker for infectious disease includes a biomarker for diagnosing bacterial and viral infection, especially new coronavirus infection; a biomarker for diagnosing pneumonias such as infectious pneumonia, especially interstitial pneumonia due to new coronavirus infection, and additionally alveolar pneumonia; and a biomarker for diagnosing exacerbation due to infection, especially for diagnosing the risk of the transition to exacerbation due to new coronavirus infection. The present invention is further a diagnostic system for detecting a biomarker for diagnosing infection comprising a sulfur metabolite from exhaled air, and is a system for determining infection, especially for diagnosing new coronavirus infection.

Abstract: A gas detector having an intake to let in the gas to be detected and detecting the gas let in through the intake by a gas sensor, in which a porous film is horizontally arranged over the gas intake, in order to prevent the gas permeability of the porous film from being affected by water, oil and/or dust riding on the porous film, wherein a water-repellant and oil-repellant porous film is horizontally provided in a stretched state over the upper end of the intake, and the outside of the outer circumferential edge of the porous film is so structured as to allow liquid on the porous film to fall externally.

Abstract: A jet opening 13a for injecting fuel can be opened and closed by a ball valve 23 of a movable element 20. An orifice plate 14 is disposed on a downstream side of the jet opening and has between about eight to eighteen circular jet holes formed for further atomizing fuel particles exhausted by the jet opening 13a. Upstream side openings of the jet holes can be dispersed on a plurality of circles. A thickness t of the orifice plate and a diameter &phgr;d of the jet holes can be set to be 0.53≦t/&phgr;d≦0.82. A shortest distance L between said upstream side openings of the jet holes and a diameter &phgr;d of the jet holes can be set to be L>&phgr;d.

Abstract: A fuel injector includes a tubular core 3 which attracts an armature 10 of a valve 12 by energizing a solenoid coil 6, and an outside magnetic path forming member 7 which partly surrounds the solenoid coil 6 and which constitutes a magnetic path M together with an armature 10 and the core 3. The outside magnetic path forming member 7 is provided with an end plate 7b having a mounting hole 8, and the core 3 is provided with a flange 3a in contact with the end plate 7b. The core 3 is inserted into the mounting hole 8 of the outside magnetic path forming member 7 such that the end plate 7b comes into contact with the flange 3a of the core 3, thus readily positioning the outside magnetic path forming member 7 on the core 3.

Abstract: An orifice plate to be mounted at a fuel jet section of an injector has a plurality of jet holes formed therethrough for injecting fuel. The orifice plate includes a curved surface formed at an inlet peripheral edge of each of the jet holes, and a cylindrical projection formed at an outlet of each of the jet holes. The cylindrical projection has the same inner diameter as that of the jet hole.

Abstract: A fuel injector including an injector casing having a fuel inlet at a side portion thereof; a valve housing having a fuel injection hole at a front end thereof and having a guide hole at an axial central portion thereof, the guide hole being communicated with the fuel inlet; a valve reciprocably accommodated in the guide hole, the valve being adjusted to close the fuel injection hole when advancing and open the fuel injection hole when retracting; a valve driving device for driving the valve to advance and retract the valve; and a fuel strainer mounted on an outer circumference of the injector casing, the strainer comprising a synthetic resin frame having annular portions at front and rear ends thereof and a metal ring connected to at least one of the front and rear end portions of the frame by insert molding of synthetic resin, the metal ring being press-fitted with the injector casing.

Abstract: An electromagnetic fuel injector comprising a fixed iron core, a solenoid formed by winding a coil around the fixed iron core, a coil holder fixed to the solenoid, an injector casing surrounding the solenoid and the coil holder and formed of a material having high magnetic permeability, a movable iron core inserted between the fixed iron core and the injector casing, a compression spring normally biasing the movable iron core toward an injection nozzle of the injector, a valve body connected at its base to the movable iron core and formed with a flange at a base portion thereof, a stopper adapted to abut against the flange of the valve body and restrict a movable range, a valve housing incorporated in a front portion of the injector casing and slidably supporting the valve body, the valve housing being formed at its front end portion with a valve seat adapted to abut against the valve body, and a radiation member closely fitted on an outer periphery of the injector casing.

Abstract: An electromagnetic fuel injector comprising a valve body composed of a spherical valve member and a hollow cylindrical slide member which is adapted to slide along a guide hole and the interior of which is a fuel passage. The slide member is provided with openings for passing liquid fuel therethrough at its peripheral wall. A circumferential clearance ranging from 4 to 30 .mu. is provided between the outer surface of the slide member and the inner surface of the guide hole. At least one of the valve member and the slide member which members constitute the valve body is formed of titanium, titanium alloy, ceramic or ferric material. With this arrangement, the slide member may be fabricated without a strictly high accuracy and the mass of the valve body may be reduced, thus increasing the response characteristics of the valve body to the on-off operation of an exciting coil.
