IPC: F23K5/04
Filed: 1988-06-10
Abstract: PURPOSE:To prevent the liquid from spilling outside from the connecting portion between an adapter and a spout, and to decrease wearing-out and deformation of a discharge pipe for extending the life-time by making the discharge pipe of the adapter of a metallic material, and providing a discharge port formed at a position on the discharge pipe lower than the lower end of the spout. CONSTITUTION:A discharge pipe 30 of an adapter 20 is made of a metallic material. The adapter 20 is connected to a spout 23 causing a valve body 43 to be pushed open by the end of the discharge pipe 30. At this state, a discharge port 38 formed on the discharge pipe 30 is located 30mm or more below the opening of the spout 23. Thereby, even if the liquid is vigorously discharged, the liquid does not spill out with air from the opening of the spout 23 because the liquid does not collide with the inner wall of the spout 23. A long life-time can be expected with less wear-out and deformation in detaching and attaching of the adapter 20 because the discharging pipe 30 is made of a metallic material.

Title: Original base cover
Inventor: NAKAHATA KIMIO
IPC: G03B27/62
Filed: 1979-11-08
Abstract: PURPOSE: To prevent a picture disorder due to deformation of the original base cover, by forming the close contact part with an original by use of a material of transparent quality, providing the reflecting surface of the original lighting beam on the reverse side of the material of transparent quality, and locating this reflecting surface out of the depth of focus of the image formation lens.  
     CONSTITUTION: The original base cover consists of a base body 1 made of rubber quality, a reflecting layer 2 obtained by performing white coating to this base body or sticking white silicon rubber, etc., and a transparent material layer 7. And the light beam reflecting surface by the reflecting layer 2 is located out of the depth of focus of the image formation lens 6. When the original is copied, the original base cover is slightly deformed, a small gap is caused between the original sheet 4 and the transparent layer 7 in several places, and a shadow of the original pattern is made on the light beam reflecting layer. In this case, when thickness of the transparent layer 7 is made 1.5mm or more, the shadow becomes blurred swiftly. Also, since the light beam reflecting surface is located out of the depth of focus of the lens, the surface of the photosensitive drum is scarcely influenced by the shadow. In this way, a picture disorder can be prevented.
