摘要:
A combustion apparatus (1) with a burner port assembly (3) comprises an elongated first array of main burner ports (53) for jetting and burning a fuel gas mixture of a concentration to make main flames. The combustion apparatus (1) comprises at least one second arrays of auxiliary burner ports (63) for jetting and burning a further fuel gas mixture of a different concentration to make auxiliary flames, wherein the second arrays of said auxiliary burner ports (63) extend along the first array of said main burner ports (53). The burner port assembly (3) is constructed using inner and outer wall segments (52) together with outermost wall segments (52a,52f) or bands (58). One of the bands (58) faces the corresponding one of said outermost segments (52a,52f) so as to define between them collateral burner ports (61a,61b).
摘要:
A combustion apparatus (1) is generally composed of a principal part (5), a supplementary part (6) and a burner port assembly (3). Four metal plates (7,8,10,11) constituting the principal and supplementary parts (5,6) are pressed to have in them several protuberances and recesses. These metal plates are laid one on another to form in them some hollow spaces and sealed regions. These hollow spaces communicate with each other to form a thin gas passage (22) together with a thick gas passage (73) in this combustion apparatus (1) in such a manner that its condition of thick and thin fuel combustion is rendered more stable.

A syringe device and a method of preparing medicine using the device capable of easily and accurately performing operations for mixing and dissolving a lyophilized product into a dissolution liquid before use. A double ended needle assembly and an intermediate holder are fitted to the first cylindrical part of a connection holder, a first syringe in which the dissolution liquid is stored is inserted into the first cylindrical part through the intermediate holder, and a second syringe in which the lyophilized product is stored in a depressurized state is fixedly inserted into the second cylindrical part of the connection holder. First, the intermediate holder is locked by a finger hooking projected piece, the first syringe is pushed into the intermediate holder in the locked state of the double ended needle assembly at an initial position by locking ribs, and the first syringe is unsealed by one end of the double ended needle. Next, the intermediate holder and the double ended needle assembly are pushed into the first cylindrical part by the first syringe, and the second syringe in the second cylindrical part is unsealed by the other end of the double ended needle.

A method of forming a pattern which comprises the steps of, forming a matrix pattern on a work film, filling an opened space in the matrix pattern with a mask material layer containing at least one kind of a network carbon polymer having a repeating unit represented by the following general formulas (CP1) to (CP4) on the work film, forming a mask material pattern by removing the matrix pattern, and forming a work film pattern by transferring the mask material pattern to the work film: wherein R is halogen atom, hydrogen atom or a substituted or unsubstituted hydrocarbon group, A is a polyvalent organic group, and m, n and k denote respectively a positive integer.
摘要:
An optical element molding method for molding an optical element having an asymmetrical optically functional surface by pressing a heated preform in which, after a center part of a transfer surface of a molding die and a center part of the preform are brought into contact with each other, peripheries of the center part of the preform are brought into contact with the transfer surface, to transfer the form of the transfer surface to the preform. Consequently, the optically functional surface shape can be favorably transferred to the preform.
