摘要:
The present invention provides an ultraviolet light irradiation device having a planer UV light source in which the irradiation intensity of UV light can be adjusted finely in a wider range. The ultraviolet light irradiation device of the present invention comprises an UV light source and a housing that holds the planer UV light source. In the UV light source, a plurality of thin plasma tubes, each of which has an UV phosphor layer formed therein, are arranged in parallel with each other on an electrode support sheet, and drive circuits apply a pulse voltage to electrode pairs provided between the electrode support sheet and an array of the thin plasma tubes. A control circuit controls a factor of the pulse voltage to be applied to the electrode pairs so as to adjust the irradiation intensity of the UV light.

An impact absorber device includes at least one first portion having a short tubular shape, and at least one second portion having a short tubular shape concentrically disposed in a stacked relationship with the first portion. The first portion and the second portion engage with each other at an engagement portion which is inclined with respect to a concentric axis of the first portion and the second portion. With this arrangement, impact energy is absorbed in the case of collision accidents of vehicles such as an automobile and trains, and the dropping accidents of lifts such as elevators.
摘要:
A first electrode is formed on a stacked-layer film, which is formed of a ferroelectric layer and a semiconductor layer, at the ferroelectric layer and a plurality of second electrodes are formed on the stacked-layer film at the semiconductor layer side. Each of parts of the semiconductor layer located in regions in which the second electrodes are formed functions as a resistance modulation element (memory) using the polarization assist effect of the ferroelectric layer. Information (a low resistance state or a high resistance state) held in a memory is read by detecting a value of a current flowing in each part of the semiconductor layer. Information is written in a memory by inverting a polarization of the ferroelectric layer.

Guiding pieces on a bracket cover is engaged with attachment claws on a bracket body. This engagement serves to hold the bracket cover on the bracket body when the bracket cover is set at a first position. When the bracket cover is set at a second position, the engagement between an engagement piece and a hook piece serves to cooperate with the engagement between the guiding pieces and the attachment claws so as to hold the bracket cover on the bracket body. The bracket cover is firmly held on the bracket body when the bracket cover is set at the second position. The bracket cover is thus reliably prevented from detachment from the bracket body.

Flow guides forming an inlet channel are formed on a surface of a metal separator of a fuel cell. The flow guides overlap a section of an outer seal provided on the other surface of the metal separator. When a load is applied to the flow guides and the overlapping section in a stacking direction of the fuel cell, the flow guides and the overlapping section are deformed substantially equally in the stacking direction to the same extent. The line pressure of the flow guides and the line pressure of the overlapping section are substantially the same. The seal length L1 of the flow guides and the seal length L2 of the overlapping section are substantially the same.

摘要:
A light emitting element is mounted on the surface of a board. The light emitting element emits light. The light passes through a translucent optical member. The light enters the translucent optical member through a incident surface. The lines of protrusions make the incident surface jagged. The jagged surface resulting from the protrusions enables diffusion of the light entering through the incident surface. The light spreads along the surface of the board. Simultaneously, the emitted light is partly reflected on the incident surface. The reflected light is reflected on a reflecting surface placed behind the light emitting element. The reflected light then enters the translucent optical member. The translucent optical member is thus allowed to illuminate over a wide range with a sufficient brightness. An impressive illumination can be realized.

The present invention provides a perfluoroelastomer seal material in which adhesive strength, contamination, corrosion and color change of a contacted surface with a seal material are improved, and an amount of an uncrosslinked polymer component is at most 1% by weight, measured under specific conditions, and a process for preparing the same. The present invention relates to a perfluoroelastomer seal material, wherein a rate of weight decrease is at most 1% by weight when the seal material is immersed into perfluoro(tri-n-butyl) amine at 60° C. for 70 hours and is dried at 90° C. for 5 hours, 125° C. for 5 hours and 200° C. for 10 hours after taken out of the emersion. And, the present invention also relates to a process for preparing a perfluoroelastomer seal material comprising a step of treating with a solvent having at least 50% of a swelling rate based on said molded article, when said molded article is immersed at 60° C. for 70 hours.
