Title: Picture input system for manual picture input device
Inventor: KOMAGAMINE KATSUMI
IPC: H04N1/107
Filed: 1987-05-19
Abstract: PURPOSE:To realize the high-level picture processing by adding a binarization processing circuit to an interface board. CONSTITUTION:In a picture input system, a manual picture input device 1 and a picture processor (interface board) 3 connected to the device 1 via a signal cable 2 can be directly connected to a CPU bus of a host computer. A binarization processor 18 is added to the system to binarize the analog signal obtained by a line sensor of the device 1 via the processor 3. Then the data binarized by the processor 3 is transferred to the CPU bus and the pictures are outputted in real time to a CRT. In this case, the data obtained by the line sensor is directly sent to the CPU bus. Thus a picture reading part is substantially separated from a picture processing part. As a result, a picture input system can be designed with an extremely high degree of freedom.

Filed: 1988-05-21
Abstract: PURPOSE:To prevent a rib from floating and prevent sound from leaking intensively out of a specific location by embedding a soft sound absorbing material in an inner space surrounded with ribs around a component passing through an insulator. CONSTITUTION:A plurality of ribs 2a are arranged in the shape of a lattice on the reverse side of an insulator 2. The insulator 2 is disposed along a body panel 1 with the fore-ends of the ribs 2a in contact with the body panel 1 to form a plurality of sound insulating closed spaces divided with the ribs 2a between the body panel and a skin material. In this case, a soft, sound-absorbing material 4 is embedded in a space surrounded with the ribs 2a around a component 3 passing through the insulator 2. As a result, the closed space is maintained even if the ribs 2a are floating from the body panel 1 due to lower accuracy of attachment of the ribs 2a relative to the body panel, and intensive noise leak due to the floating of the ribs 2a is avoided. As a result, uniform sound insulation effect is obtained.
