Title: Extinction filter device
Inventor: HAYASHI NOBUTAKA
IPC: G02B5/22
Filed: 1984-06-06
Abstract: PURPOSE:To execute continuously an adjustment of a light quantity by superposing suitably two filter elements whose transmissivity is varied linearly, and also whose variation ratios of transmissivity are equal, and placing one filter element so as to be movable along the direction in which the transmissivity is varied with respect to the other filter element. CONSTITUTION:A variation ratio of the transmissivity of each element A, B is shown by a gradient of characteristic lines (a), (b), and (a) and (b) become right-down and right-up, respectively, at the same inclined angle, therefore, in the part where both the elements A, B are superposed, a variation of the characteristic line (a) is negated by (b), and extending from the right end of the element B to the left end, a prescribed transmissivity as shown by a horizontal part (c) is obtained. The position of the direction of an axis of ordinate of this horizontal part (c), namely, the magnitude of the transmissivity is varied in accordance with a position where the elements A, B are superposed, and it becomes large and small, when the element B is in the left direction, and when it is in the right direction, respectively. In this way, a continuous variation of the transmissivity can be executed, and when the whole aperture of a lens is covered in the part where the elements A, B are superposed, a light which is made incident on the lens becomes that which has been brought to extinction by a uniform transmissivity.

IPC: H04L12/40
Filed: 1991-05-22
Abstract: PURPOSE:To attain total management of operating parameters by reducing an operation parameter calculation time and improving the quality of the operating parameter in the network system. CONSTITUTION:A parameter setting element acquisition section 7 of a network management node 2 acquires a parameter setting element in response to the current state of the network from a transmission line 1 from each prescribed time and a fuzzy deduction section 91 generates a new operating parameter by using the parameter setting element and an operating parameter setting value such as a communication cycle time stored in a storage section 5 as input values. The generated parameter is compared with the operating parameter setting value in the storage section 5 and when they are non coincident, the content in the storage section 5 is rewritten into a new operating parameter. Then an operating parameter setting section 8 sends the operating parameter to another node together with a rewrite command to set a new operating parameter to another node.

Title: Screw rotor machine
Inventor: DEBITSUDO HATSUKU
IPC: F04C18/16
Filed: 1985-05-29
Abstract: A screw rotor machine for compressing air or other working fluid comprises a housing (11) including two intersecting bores axes which together define a working space (14). The pair of intermeshing rotors (22, 23) are rotatably mounted one in each bore. The rotors have helical lands and intervening grooves whereby rotation of the rotors in connecting engagement is effective to compress the working fluid (or to expand the fluid if the machine is used as an expander). A low pressure port (16) and a high pressure port (19) formed in the housing at opposite ends thereof permits inlet and outlet of the working fluid. The grooves (28, 34) of the rotors each have a primary flank (31, 37) and a secondary flank (32, 38). The tips of the primary flanks of both the male and female rotors are formed by parabolic arcs which generate major portions of one of the flanks of the opposite rotors. A major portion of the secondary flank of the female rotor is also a parabolic arc.
