摘要:
In, for example, a direct methanol type fuelcell, fuel is allowed to be injected little by little when the fuel is injected and supplied from the outside to a fuel receiving part reduced in the amount of remaining fuel on the fuelcell body side and an electromotive part can be prevented from being damaged by keeping the pressure in the fuel receiving part at a fixed level or less when the fuel is injected. Specifically, when a fuel CL filled in a refuelling container C is injected into a fuel receiving part T in several lots, a fuel injecting operation is repeated in which the volume of the refuelling container C is shrunk and reduced to supply the fuel into the fuel receiving part T in a proper amount and then the original volume of the refuelling container is restored to thereby absorb the atmospheric gas in the fuel receiving part T, which makes it possible to inject fuel continuously without any hindrance to the injection of the fuel.

Liquid fuel received in a container can be injected manually in a safe, easy and convenient manner. In a fuel cell cartridge for fuel cells in which at a port portion (14) of the container (10) in which the liquid fuel is received, there is provided a plug (30P) that is adapted to be connected with a fuel cell for filling the fuel thereinto, a bellows portion (15) acting as a portion capable of extension and contraction is formed in at least a part of the container (10), and on the plug (30P), there is provided a valve mechanism (34) which is held in a normally closed state in a free state thereof, and is opened when the plug is connected with the fuel cell (70).

A fuel bottle 10 for a fuel cell having a bottle main body 12 for containing fuel for a fuel cell and comprising a nozzle portion 11 at the tip portion of the bottle main body 12 on which a coupler for connecting with a main body of a fuel cell can be attached and a trunk portion having a generally elliptic shape in cross section and having been formed by blow molding. In this bottle 10, length L1 in one direction of minor axis from the center On of the nozzle portion of the elliptic shape in cross section differs from length L2 in the other direction of the minor axis from the center On of the nozzle portion. By this structure, a moving space of a push button when the fuel bottle 10 is housed in a hard case can be secured while necessary capacity of the fuel bottle 10 is secured. Pinch portions 13 and 14 are formed in lowly stretched portions of the bottle main body 12 in a manner to protrude outwardly whereby contact areas of the pinch portions 13 and 14 are increased and contact strength thereby is improved.

An intraocular lens insertion device having a novel configuration, capable of more accurately arranging front and back surfaces of an intraocular lens in a proper direction. The intraocular lens insertion device is adapted in such a manner that the intraocular lens is set on a stage in a state placed flat with a pair of haptics extended facing front and back sides in a movement direction by a plunger. Also, an interfering acting part is provided to an insertion tube part, and the interfering acting part interferes with the haptic, which is extended facing the front side in the movement direction of the intraocular lens moved by the plunger, to apply on the haptic an external force toward the back side in the movement direction. Thus, the interfering acting part curves and deforms the haptic to a side approaching an optical portion.

An insertion tool of an intraocular lens permits the lens to be deformed while rotation of the lens in an insertion tube is effectively prevented. Upper and lower flat planes are formed to spread flatly over a length of a through hole in the insertion tube and the upper and lower flat planes are connected smoothly with right and left wall faces over the length of the through hole. The right and left wall faces have longitudinal linear portions extending substantially in parallel in a vertical direction on a proximal end opening side. With its radius of curvature decreasing gradually in a covered shape which becomes inwardly concave as it approaches a distal end opening the upper flat plane gradually approaches the lower flat plane, and a tapered portion having a reduced cross-sectional area is formed, thus obtaining the distal end opening of substantially oval shape.
摘要:
An intraocular lens insertion tool with a tool body for accommodating an intraocular lens and adapted to insert into an eye the intraocular lens through displacement of the lens in an axial forward direction by a plunging member, and to push out the lens through an insertion tube section disposed at an axial distal end of the tool body. The insertion tube section has an inclined orifice that opens on diagonal to the center axis of the insertion tube section. The plunger member has a sliding part that during displacement thereof in a direction of plunging into the tool body will slide against the tool body. A resistance graduating mechanism is provided for gradually increasing operation resistance of the plunger member by gradually increasing contact force on the sliding part as the lens gradually emerges from the inclined orifice through plunging of the plunger member into the tool body.

A one-piece intraocular lens realizing adhesion of the intraocular lens to the inner surface of a capsule more advantageously by viscosity imparted to the intraocular lens, and being deployed more positively after it is inserted into the capsule and secured therein while being positioned at a specified location. The intraocular lens has an optical portion (12) and supporting portions (16, 16) that are formed integrally with a soft material exhibiting viscosity, wherein viscosity reducing portions (32, 32) having irregularities are formed on at least one-end faces of the supporting portions (16, 16) in the longitudinal direction.

Multi-level modulation that is hardly affected by non-linear characteristics of a power amplifier and is equal to or above 64-valued quadrature amplitude modulation (64-QAM) is provided.N (integer equal to or above 3) quadri-phase shift keying (QPSK) outputs having different amplitude levels, i.e., r2=r1·2−(i−1), i=2 . . . N with respect to a maximum amplitude level r1 are superposed after power amplification to form M(=22N)−valued/quadrature amplitude modulation (QAM), and N-1 outputs si except the quadri-phase shift keying QPSK-1 having the maximum amplitude r1 are subjected to power amplification in this formation, then the outputs are combined by a directional coupler to obtain a combined signal, and an output of the quadri-phase shift keying QPSK-1 and the combined signal are transmitted from two systems of antennas to be vectorially superposed and combined in a space. A series/parallel converter is provided before each QPSK unit to divide and input input data of 2N bits, and a variable gain unit and a variable phase shifter adjust a gain and a phase.
