摘要:
The object of the invention is to provide a fuel injection nozzle with which occurrence of cavitation erosion due to occurrence of separation of fuel flow near the needle valve and injection holes is suppressed and variation in fuel injection characteristic is reduced, a method of machining injection holes, and an apparatus therefore to attain the object. An insert tool shaped like the needle valve or an insert tool having a conical surface similar to the needle valve and a groove or grooves are on the conical surface to introduce abrasive fluid to the injection holes, is inserted in the central hollow of the nozzle body when performing abrasive fluid flowing processing to round entrance corners of the injection holes, and the processing of each of the injection holes is stopped when flow rate of abrasive fluid flowing out through relevant injection hole reaches a predetermined value.

A method for treating a liver disease such as hepatitis, comprising administering to a patient having the liver disease, an effective amount of a diarylsulfide or diarylether derivative having 2-amino-1,3-propanediol structure, and represented by the following formula (1): or a pharmaceutically acceptable salt thereof.
摘要:
An output-side swing arm is adapted to be swung about a swing axis thereof when the output-side swing arm is urged by a corresponding part of an input-side swing arm, which is driven by a force transmitted from an input shaft. An adjusting mechanism adjusts an amount of swing of the output-side swing arm by changing a location of a point of action of the input-side swing arm relative to the output-side swing arm in a radial direction of the swing axis of the input-side swing arm.

A shaft for a golf club comprises a plurality of fiber-reinforced resin layers. A plurality of circumferentially oriented metal wires are provided at intervals of 1 mm to 4 mm in an axial direction of the shaft having a length in an axial direction of more than 100 mm and less than 300 mm and being centered at a position of 3.25×102 mm from a larger-diameter end of the shaft.
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.

A textile dyeing method includes a drying step 100 of drying a natural material within a set temperature range in which a coloring component of the natural material is hardly altered, thereby bringing the natural material into an absolutely dried state or a nearby state, a pulverizing step 200 of pulverizing the dried natural material obtained in the drying step 100 into fine powder of not larger than particle size being passable through at least 80 mesh in terms of sieve standards while controlling temperature of the natural material not to exceed the set temperature range, and a dyeing step 300 of mixing and dispersing the fine powdery natural material into a liquid, and immersing a textile in the liquid containing the fine powdery natural material in suspended condition, thus causing the fine powdery natural material suspended in the liquid to be physically attached to the textile.
摘要:
An external combustion engine provided with a pipe-shaped main container with a heating portion and a cooling portion, an output part converting displacement of the liquid part of said working fluid generated due to the change in volume of said working fluid accompanying generation and condensation of said steam to mechanical energy for output, a venturi provided at a communicating part of the main container and an auxiliary container, a communicating member forming a communicating passage bypassing the venturi and communicating the main container and the auxiliary container, and a shutting means for closing the communicating passage at the time of normal operation and opening the communicating passage at the time of startup, wherein at the time of startup, the pressure loss at the communicating passage becomes smaller than a saturated steam pressure at the temperature of the heating portion.
摘要:
An external combustion engine alternately repeating a first stroke of making a working fluid evaporate at a plurality of heating portions and making a liquid phase part of the working fluid displace toward an output part side and a second stroke of making the working fluid evaporated at the first stroke condense at the plurality of cooling portions and making the liquid phase part of the working fluid displace toward the side of the plurality of the heating portions and provided with inflow adjusting means for reducing differences in inflows among the plurality of the heating portions, wherein the inflow is defined as the amount of a liquid phase part of the working fluid flowing into the heating portions when the liquid phase part of the working fluid displaces from the output part side to the side of the plurality of the heating portions in the second stroke.
