Title: Float structure
Inventor: MATSUMOTO KOICHIRO
IPC: B63B35/44
Filed: 1986-04-18
Abstract: PURPOSE:To enable the operation to be stably performed by a processing equipment on a float, by decreasing the sectional beam of a float main unit from its deep draft line to shallow draft line and holding metacenter height CM equivalent to when the float main unit is in the deep draft line in no relation to a change of the draft. CONSTITUTION:A sectional width from a deep draft line (deep draft dF) reaching a shallow draft line (shallow draft dE) is gradually decreased, and the metacenter KM is prevented from increasing larger than when a float is in the deep draft dF. In this way, metacenter height CM almost in a fixed value is set so as to be in the equivalent value to when the float is in the deep draft dF in no relation to a change of draft. That is, the float, which suitably sets a tilt angle thetaformed by a line A-B gradually decreasing the sectional width from the deep draft line to the shallow draft line, holds the value GM equivalent to when the float is in the deep draft in no relation to the change of the draft, in this way a small response of rolling and pitching can be expected even in the shallow draft. Consequently, an operation by a processing equipment on the float can be stably performed with no large influence by a storage amount of processing oil on the float and waves or the like.

IPC: H04N1/028
Filed: 1985-04-24
Abstract: PURPOSE:To form a contact type image sensor reading an original in contact with the original by providing a lens to the rear side of a light-transmitting insulation substrate. CONSTITUTION:The lens 13 for condensing light 10 from a light source 9 on an original face 11 through a lighting window 3 is fixed to the rear side of the transparent insulation substrate 1. Since the irradiated light 10 of the light source 9 enters the lens 13, passes through the lighting window 3 and is condensed on the original face 11, all the irradiated light is condensed on the original face 11 in comparison that only the parallel light made incident on the lighting window 3 is irradiated on the original face 11 and the outer light is reflected conventionally, and the light quantity is increased remarkably, then the power consumption of the light source 9 required to obtain the same original face light quantity is lowered and heat dissipation is also decreased.
