A wiper apparatus for use in a motor vehicle with a pivot extending from an interior side of a vehicle body toward the external and penetrating a pivot holder that is fixed integrally onto the vehicle body. The pivot is rotatable with respect to the pivot holder and further holds a wiper arm at its penetrating tip portion. An outer circumferential surface of the pivot has an engaging groove that is fitted with an elastic retainer ring to retain the pivot on the pivot holder. An upper side surface of the engaging groove is an inclined surface so that the retaining ring can get out of the engaging groove with the aid of the inclined groove side surface when the pivot is pressed downwardly. Thus, the pivot can be easily removed from the pivot holder for replacement or the like, and if a large shock load acts on the pivot, it is possible to prevent the shock load from reaching the entire wiper apparatus or the vehicle body.

Also disclosed is a process for producing the solid-ink printing original plate.
摘要:
An electro-luminescent conversion light emitting device for use in an information communication field. The light emitting device includes a semi-transparent reflective film substrate. On the semi-transparent reflective film is formed a transparent conductive film. On the transparent conductive film is formed a light emitting layer of organic thin film on the transparent conductive film. On the light emitting layer is formed an electrode. The semi-transparent reflective film 2 transmits parts of the light emitted by the light emitting layer to the glass substrate and reflects parts of the light to the light emitting layer. The semi-transparent reflective film acts as a light resonator with the Ag-Mg metal electrode on back of the light emitting layer.
摘要:
A first half-mirror, a buffer layer, a second half-mirror, a transparent electrode, an organic luminescent layer and a metal electrode which also serves as a reflector are formed on a transparent substrate thereby to constitute a first resonator between the second half-mirror and the metal electrode and a second resonator between the first half-mirror and the metal electrode. Light output of a desired wavelength is obtained from the light emitted from the organic luminescent layer utilizing resonance characteristics of the first and second resonators.
