Title: Fluid-sealed type vibrationproof bush
Inventor: MIYAGAWA SHINJI
IPC: F16F13/14
Filed: 1987-12-21
Abstract: PURPOSE:To eliminate an expensive solenoid valve mechanism, by a method wherein, by deformation of a flexible film through outflow and inflow of working fluid through the port of a port member, throttle passages are respectively opened and closed. CONSTITUTION:When working fluid is forced to flow through a port 48 of a port member 18 to a space between an outer cylinder metal 12 and a rubber sleeve (flexible film) 16, the rubber sleeve 16 is pressed against the outer peripheral surface of a rubber resilient body 14 to close a throttle passage 42. Thus A route between fluid chambers 32 and 34 is disconnected, the fluid chambers 32 and 34 are prevented from a change in volume, and spring characteristics in a opposing direction between the fluid chambers is hardened. Meanwhile, when the working fluid is forced to flow out from a space between the outer cylinder metal 12 and the rubber sleeve 16 through the port 48, the rubber sleeve 16 is adsorbed to the outer cylinder metal 12 side to open a passage 42. Thus, since the change in volume of each of the fluid chambers 32 and 34 is produced by fluid of non-compressive fluid through the passage 42, spring characteristics in an opposing direction between the fluid chambers are softened.

Title: Measuring operation method of boiling water nuclear power plant
Inventor: FUJII TOSHIHIRO
IPC: G21C17/032
Filed: 1995-11-20
Abstract: PROBLEM TO BE SOLVED: To calculate the true reactor core flow from a measured reactor core flow by conducting operation in a specified formula on the basis of a measured value, a primary delay time constant and a Laplace operator in the case where a primary delay characteristic is provided in obtaining a measured value from the true value of physical quantity. SOLUTION: A recirculating pump 2 circulates cooling water in a reactor pressure vessel 1, and a reator core support plate 4 fixes nuclear fuel 3 to the vessel 1. A differential pressure between the upper and lower sides of the support plate 4 measured by an instrument piping 5 is converted to a current signal by a differential pressure converter, and a computer system 7 computes a reactor core flow W (t) from the reactor core support plate differential pressure P' (t). At this time, if a primary delay characteristic is provided in obtaining a measured value from the true value of physical quantity, a measuring device 9 to which the flow W' (t) is input obtains the true value XS from the expression: XS=(1+TS)Y(S), taking the flow W'(t) as Y(S), primary delay time constant as T, and Laplacian as S.  Thus, it is possible to obtain the true reactor core flow from which the influence of time delay of the instrument device for measuring the physical quantity is removed.
