Title: Boom structure
Inventor: IMANISHI AKIRA
IPC: B66C13/12
Filed: 1994-06-28
Abstract: PURPOSE:To provide a boom structure which does not damage an oil feed hose provided in a boom during the telescopic motion of the boom, and is lighter in weight and can increase its strength. CONSTITUTION:Driving force transmitting member holding spaces 21d, 21e are formed by providing reinforcing partitioning members 21b, 21c which extend longitudinally in a boom member 21 and moreover stretch vertically in the boom member 21, and oil feed hoses H, H' serving as the power transmitting member and a wire W are arrangably composed. Thus, since the driving force transmitting member such as the oil feed hose H moving longitudinally in the boom during the telescopic motion of the boom does not come into contact with an expansion cylinder 24 arranged in the boom, and moreover external force acting on the boom does never directly act, the oil feed hose H or the like is not damaged. In addition, the vertical deflection of the boom member can be checked by the reinforcing partitioning members 21b, 21c provided so as to vertically stretch in the longitudinal direction of the boom member.

Filed: 1989-06-29
Abstract: PURPOSE:To obtain an image with high reliability and high image quality which is excellent in dimensional stability by providing a silicone rubber elastic layer, an oil barrier layer made of fluororubber and a specified releasing layer on a metallic shaft core. CONSTITUTION:By providing the elastic layer 2 made of the silicone rubber having high thermal conductivity, an appropriate hardness is accomplished and the responsiveness to heat from a heat source provided inside a shaft core becomes excellent, then it is possible to delay the deterioration of the rubber layer near a boundary between the shaft core and the rubber layer. Then, the oil barrier layer 3 made of the fluororubber is provided to cover the elastic layer 2, so that silicone oil applied to the surface of a roller as offset prevention liquid is prevented from penetrating even into the elastic layer and causing a failure. The releasing layer 4 is formed on the surface of the roller by using a composition consisting of resin-reinforced 100% siloxane which does not contain a solid filler such as active silica. Therefore, the roller excellent in releasing from toner and surface smoothness is obtained. Thus, the high-quality image is fixed for a long time.

Abstract: PROBLEM TO BE SOLVED: To easily provide legible additional information into a generated image, in the case of generating a binary color image, by generating a binary image signal having a plurality of recording dots, having a prescribed position relation to each other. SOLUTION: For example, a mark is configured by 72 picture elements, and three pixels area adopted for B pixels and the position is fixed definitely and its level is set to a highest density '255'. In the case of applying binarization to the 72 pixels, three dots 108, 109, 110 are generated independently of a substantial image signal. Since the position relation of the three dots is fixed, it is easy to identify the mark position from the generated image. Thus, A binary mark depending on the additional information is provided for each prescribed line interval of a Y (yellow) signal. Since the pixel position, corresponding to the B-pixel being always set (black level pixel) is fixed in this mark, the mark is easily identified from the formed image, and the additional information is analyzed accurately.
