摘要:
A medium oil to be used for a synthesis reaction in a slurry-bed reaction procedure. The medium oil has as a main component, a branched, saturated aliphatic hydrocarbon having 16 to 50 carbon atoms, 1 to 7 tertiary carbon atoms, 0 quaternary carbon atoms, and 1 to 16 carbon atoms in the branched chains bonded to the tertiary carbon atoms; and at least one of the tertiary carbon atoms is bonded to hydrocarbon chains with a chain length having 4 or more carbon atoms in three directions.

A simple, inexpensive and highly efficient fuel cell has boundary structures made of a photo-sensitive material in combination with selective patterning. Printed circuit board (PCB) fabrication techniques combine boundary structures with two and three dimensional electrical flow path. Photo-sensitive material and PCB fabrication techniques are alternately or combined utilized for making micro-channel structures or micro stitch structures for substantially reducing dead zones of the diffusion layer while keeping fluid flow resistance to a minimum. The fuel cell assembly is free of mechanical clamping elements. Adhesives that may be conductively contaminated and/or fiber-reinforced provide mechanical and eventual electrical connections, and sealing within the assembly. Mechanically supporting backing layers are pre-fabricated with a natural bend defined in combination with the backing layers' elasticity to eliminate massive support plates and assist the adhesive bonding. Proton insulation between adjacent and electrically linked in-plane cell elements is provided by structural insulation within the central membrane.

In a fuel cell assembly (1) comprising a pair of separators (11, 12) each for defining a recess (10) serving as a conduit for a fuel fluid or an oxidizer fluid, a feedthrough conductive path for connecting top and under surfaces of each separator is achieved by a second electroconductive film (36) formed on a side wall of a through-hole (33) extending through each separator (11, 12) in such a manner that the second electroconductive film (36) connects a first electroconductive film (35) constituting a top surface of a projection (30) provided in the recess (10) to a third electroconductive film (37) formed on a surface opposite to that formed with the recess (10).

摘要:
In a fuel cell comprising a tubular casing, an electrolyte layer received in the tubular casing, and a pair of gas diffusion electrodes interposing the electrolyte layer and defining a fuel gas passage and an oxidizing gas passage, respectively, each gas diffusion electrode is formed by stacking a plurality of layers of material therefor, for instance in the axial direction of the casing. Because the gas diffusion layers are formed layer by layer, components can be formed in highly fine patterns so that a highly compact tubular fuel cell can be achieved. Similarly, the dimensions of the various elements of the fuel cell can be controlled in a highly accurate manner. Also, the geometric arrangement can be changed at will in intermediate parts of each gas passage.

It is an object of the invention to provide an opening/closing rear component structure of a vehicle, comprising a luggage space being divided into a upper luggage space and a lower luggage space, a openable/closable door being provided to the upper luggage space and the lower luggage space respectively, and the door for the upper luggage space and the door for the lower luggage space being adapted to selectively adopt either a mode of opening/closing the door for the upper luggage space and the door for the lower luggage space integrally so that the upper luggage space and the lower luggage space may be opened/closed at the same time, or a mode of, opening/closing the door independently so that the upper luggage space and/or the lower luggage space may be opened/closed, whereby it becomes possible to selectively adopt an independent luggage space separated from the compartment (such a luggage space as a sedan-type vehicle has) or a large luggage space in which large luggage can be loaded and unloaded easily (such a luggage space as a hatchback-type vehicle has), and it becomes also possible to keep the air-conditioning from lessening its effect when the independent luggage space is opened/closed, and also possible to store, for example, dirty luggage and the like in the independent luggage space.
摘要:
A waterproof connector housing is provided. This waterproof connector housing includes a housing main body, a hood portion for engaging with a mating housing via a stair portion provided on the housing main body, an elastic seal ring for maintaining water-tightness with the mating housing inside the hood portion, and a holding portion for the elastic seal ring on the terminal insertion surface of the housing main body. With this waterproof connector housing, the elastic seal ring can be easily molded, and the amount of wasted raw material can be dramatically reduced. Also, the hood portion can take various forms and be made smaller.
