An intravascular obstruction removing wire includes an elongate wire body, at least two non-branched wire portions having distal ends and proximal ends which are connected to a distal end of the wire main body, and a plurality of filament portions extending across the wire portions. The non-branched wire portions and the filament portions form a trapping portion. The trapping portion is deformable from a large-diameter state in which the non-branched portions branch to the distal end of the wire body forward in different directions and the filament portions are separated from each other, so that a space surrounded by the non-branched wire portions and the filament portions is formed to trap therein an obstruction in a blood vessel, to a small-diameter state in which the non-branched wire portions are positioned so that a distance between the wire portions is smaller than that of the wire portions in the large-diameter state.

An external combustion engine 10 is disclosed, wherein a container 11 sealed with a working medium adapted to flow in a liquid state includes a heating unit 13 for generating a vapor of the working medium 12 by heating part of the working medium, and a cooling unit 14 for liquefying by cooling the vapor. The volume of the working medium 12 is changed by the generation and liquefaction of the vapor, and the displacement of the liquid portion of the working medium 12 caused by the volume change of the working medium 12 is converted into and output as mechanical energy. The heating unit 13 is structured so that inner members 51a, 53a arranged on the inside and outer members 51b, 53b arranged on the outside are bonded to each other. The outer members 51b, 53b are made of a second material higher in heat resistance than the first material of the inner members 51a, 53a. Further, the thickness of the inner members 51a, 53a is not smaller than the thermal penetration depth δ of the first material.

A fuel injection system for an internal combustion engine has a lubricity improver supply for adding a lubricity improver to low-viscosity fuel supplied to a fuel injection apparatus of the engine. A controller controls the lubricity improver supply so that the amount of the lubricity improver added to fuel at the inlet to the fuel injection apparatus is increased as engine rotation speed, engine load, or injection pressure is increased. With the system, wear or sticking of the plunger can be prevented even when low-viscosity fuel is used by improving lubrication conditions to secure necessary lubrication condition for the sliding part in accordance with engine operation conditions, fuel temperature and viscosity.

The present invention relates to a portable wireless terminal, and in particular, a portable wireless terminal such as a cellular phone, etc., and its security system that can reliably prevent, by remote control, improper use of the portable wireless terminal by a third party when it is lost or stolen. The portable wireless terminal that uploads backup data to a center by remote control from the center via a wireless network includes: a data access control section 1-1 that, in response to an instructions from the center, prohibits access to the backup data retained by a portable wireless terminal or deletes the backup data; an encryption section 1-5 that encrypts the backup data by using a public key notified from the center or a public key owned by the portable wireless terminal itself in response to instructions from the center; and a data transmission section 1-2 to 1-4 that transmits the backup data split into a plurality of data fragments on a plurality of communication paths to the center according to transmission priority of the backup data that is notified from the center or owned by the portable wireless terminal itself.
摘要:
An accumulator fuel injection system has fuel pressure pulsation in a common rail caused by fuel injection suppressed in an extremely simple way with a low cost system and without using an electronic control device and so on. The accumulator fuel injection system supplies high pressure fuel accumulated in an accumulating room of the common rail through high pressure fuel outlets provided equally spaced along the longitudinal direction of the common rail to a fuel injection valve of each cylinder at predetermined injection timing. The distance from an end of the accumulating room, from where a pressure wave generated therein is reflected, to a high pressure fuel outlet adjacent to the end (L1 or L2) is determined in a range of (N+0.25) times to (N+0.375) times the pitch length L of the equally spaced high pressure fuel outlets each corresponding to each cylinder, N being a nonnegative integer.
摘要:
The force to draw an armature of an electromagnetic valve apparatus driving a valve for opening or closing a high-pressure liquid passage is increased and valve bouncing is alleviated by a surface of the core being flat and a surface of the armature facing the surface of the core being shaped convexly spherical. Interference of the surfaces is prevented by a smaller initial gap in a central portion of the faces, even when the armature is installed aslant due to insufficient accuracy of the component parts. Strong electromagnetic attraction can be secured because the smaller the gap is, the stronger the electromagnetic attraction.

The poppet valve device is composed such that a plurality of axial passages of substantially the same diameter and length communicating to the high-pressure room formed inside the valve seat member between the poppet valve body and the valve seat member are provided in the valve seat member, the passages being located adjacent to each other, or passages being located axially symmetrically, and the annular gap formed between the periphery of the poppet valve body and the inner perimeter of the projecting part on which the valve seat face of the valve seat member is formed is narrow to restrict liquid flow through the annular gap. The electronic controlled fuel injection apparatus equipped with the poppet valve device is composed such that the lower end part of the poppet valve body and the bottom of the valve device accommodating part of the fuel injection apparatus are formed to restrict the flow of the fuel between the lower end of the poppet valve body and the bottom of the valve device accommodation part to the central hollow of the poppet valve body, whereby the occurrence of bouncing is prevented.
