Filed: 1990-05-28
Abstract: PURPOSE:To realize KL (Karhumen-Leave) transformation with a device where the bit precision is limited by preserving the dynamic range before and after KL transformation. CONSTITUTION:N color components are successively inputted to a covariance matrix calculating part to calculate a covariance matrix. This covariance matrix is delivered to an intrinsic right and intrinsic vector calculating part 2 to obtain (n) intrinsic values and (n) intrinsic vectors corresponding to them, and an nxn matrix consisting of these intrinsic vectors is inputted to a transformation part 3 and an inverse matrix calculating part 5. After the end of these processings, (n) color components are inputted to the transformation part 3, and components transformed by this transformation part 3 are multiplied by 1/ n in a constant multiplying part 4 to output transformed data. A transformation matrix for inverse transformation is simultaneously obtained in the inverse matrix calculating part 5. KL transformation is realized without the occurrence of overflow in the condition of the limited bit precision.

Title: Device for controlling air-fuel ratio of internal- combustion engine
Inventor: KATOU KENJI
IPC: F02M7/28
Filed: 1981-09-01
Abstract: PURPOSE:To prevent the fluctuation of an output torque by a method wherein a vacuum delay valve, connecting the vacuum chamber of a vacuum diaphragm device, controlling the opening and closing of an air bleed port, to a suction air path, is provided. CONSTITUTION:The opening and closing control valve 14 is secured to a diaphragm 11 to effect the operning and closing control of the air bleed port 9. The vacuum delay valve 16 is arranged in a vacuum introducing pipe 15 connected to the vacuum chamber 12 of the diaphragm device 10. The vacuum delay valve 16 is consisting of a non-return valve 20 and a throttle valve 21. When a vacuum in the suction air path 2 becomes smaller than a set value, the non- return valve 20 is opened and the opening and closing control valve 14 closes the air bleed port 9. When the vacuum of the suction air becomes larger than the set value, the non-return valve 20 is closed and air in the vacuum chamber 12 cannot be flowed out gradually through the throttle valve 21, therefore, the opening and closing control valve 14 continues to close the air bleed port 9. According to this method, the fluctuation of torque may be prevented.

Abstract: PURPOSE:To prevent an externally extended part of an inner pipe from radially expanding without precluding its axial contraction caused by a radial increase of the pipe, by providing an expansion preventing and pipe reinforcing means, having a diam. smaller than the internal diam. of an outer pipe, to the externally extended part of the inner pipe lapped in layers onto the pipe. CONSTITUTION:An inner pipe 2, formed to have a preliminary set, externally extended and radially small part 2' through a tapered and radially contracted part 2'', is inserted into a heated and radially expanded outer pipe 1 having a prescribed length in a cooled and radially contracted state of the pipe 2, and a reinforcing body 4 of which an external diam. is approximately the same as that of the inner pipe 2 and is smaller than the internal diam. of the pipe 1, is fitly inserted to the pipe 2'. Next, when cooling water is supplied, filled and pressurized as a pipe expanding liquid, the pipe 2 is increased in diam., and also the outer pipe 1 is radially expanded in a state of plastic deformation. During this time, though the pipe 2 contracts axially with an increase of its diam., the part 2' is precluded from radially expanding because the body 4 enters the inside of the pipe 1 and the body 4 is fitly attached to the part 2'.
