Title: Capacity controller of variable hydraulic pump
Inventor: FUJIMA HIDEKI
IPC: F04B49/00
Filed: 1978-12-25
Abstract: PURPOSE: To keep the consumption torque of a stationary pump matched with the total consumption torque of variable hydraulic pumps at the maximum output point of a driving source regardless of load or no load of the pump, by reducing the viriable pump's consumption torque by just as much as the stationary pump's consumption torque.  
     CONSTITUTION: The discharge pressure P 2 , P 1 , P 3  of variable hydraulic pumps 50, 51 and a stationary pump 30 is introduced to the right chambers of pins 24, 23, 25, respectively. When the stationary pump's pressure is P 3 , the relation of (P 1 +P 2 ) to the discharge pressure q is shown by straight lines 9, 10 and the total torque of the hydraulic pumps 50, 51 decreases. The lines 9, 10 are almost approximate to an ideal curve, for other poins, when the stationary pump 30 is under no load. Subsequently, the total consumption torque of hydraulic pumps 50, 51 is reduced by just as much as the consumption torque T 3  of the stationary pump 30 when the pump 30 is under no load, and both torque are matched with each other at the maximum output point, regardless of whether the stationary pump 30 is under load or no load.

Title: Shape measuring instrument for cylinder body
Inventor: NAGAHISA TOMOAKI
IPC: G01B11/24
Filed: 1990-06-19
Abstract: PURPOSE:To easily and accurately measure the crowning shapes of both end parts of the cylinder body and the angle to the center line in a short time by irradiating the cylinder body with a light beam through an optical system from outside the right- angled direction of a reference surface and obtaining interference fringes formed by the interference between reflected light from a surface to be measured and reflected light from the reference surface by an interference fringe analytic processor. CONSTITUTION:The monochromatic light emitted by a light source is expanded to light the component surface and the reference surface and its reflected light is converged on an image input part 11 through a lens 10. At this time, the shape of the component surface based upon the reference surface is obtained from the observed interference fringes. Namely, the interference fringes are contour lines intervals of lambda/2 height from the reference surface because of the constant relation between the interval between the reference surface and measured surface and the wavelength lambdaof the light source 6 at each point on the image lane. They are inputted to an input part 11 and image processing 12 and analysis 15 are carried out to obtain the shape. After both flanks are measured, the sectional shape is constituted according to the interval angles of the reference surface.

Title: Separation of terephthalic acid particle from filter medium
Inventor: TOKIYAMA YASUHIRO
IPC: C07C67/00
Filed: 1978-12-22
Abstract: PURPOSE: To prolong the life or a cleaning cycle of a filter medium for the separation of BHET, by thoroughly removing fine particles of terephthalic acid accumulated on a filter medium through reverse pressure cleaning with ethylene glycol vapor.  
     CONSTITUTION: In the operation of separating transparent BHET, by filtration, from a mixture of esterification products wherein terephthalic acid and ethylene glycol are used as principal raw materials, terephthalic acid particles accumulated on a filter medium are removed through cleaning by passing ethylene glycol vapor under pressure from the downstream side of the filter medium. Even fine terephthalic acid particles which cannot be thoroughly removed by conventional reverse pressure cleaning using an inert gas or steam, can be easily separated from the filter medium because the size of the particles is reduced by the esterification with ethylene glycol vapor and the sublimation is promoted with the stream of ethylene glycol vapor.
