Abstract:
The present invention is to provide a display device capable of displaying a prescribed display pattern by making the pattern luminous as needed, while the rear side can usually be seen through easily. In order to achieve it, a display pattern 20 is formed with minute recesses 29 provided on at least one surface of a translucent substrate 10, and at least one light source 30 is disposed on a side end face of the translucent substrate 10. The area density of the minute recesses 29 constituting the display pattern 20 is set to not more than 20%, and the opening area of one recess 29 is set to not more than 0.03 mm2.
Abstract:
A contact formed by electroforming and extended in a direction roughly perpendicular to a voltage application direction in the electroforming has a contact portion disposed at one end of the contact, which is brought into sliding contact with a conductive member along the voltage application direction in the electroforming.

Abstract:
A resin molding body has two faces (front face 15 and lower face 19) perpendicular to each other, and also has a total reflecting face 23 approximately having an angle of 45° with respect to these two faces. Plural collimating lenses 16 and a spacer 17 are integrally formed on one face. Plural collimating lenses 20 and a spacer 21 are also integrally formed on the other face. A wall taking-away portion 26 is concavely arranged between the two faces so as to be located on the rear face side of the total reflecting face 23. Guide holes 18, 22 for inserting guide pins thereinto and connected to optical connectors, etc. are bored on the two faces of the resin molding body.
