Title: Optical mechanism for detecting displacement of displacement member in apparatus for inflammable gas
Inventor: SAITO TOSHIHARU
IPC: G01B11/00
Filed: 1987-08-27
Abstract: PURPOSE:To make it unnecessary for an operator to go for detection and thereby to save time and labor, by a method wherein the displacement of a displacement member of the main body of an apparatus is detected sequentially in the main body of a detector constructed remote from the main body of the apparatus. CONSTITUTION:A scale 3 showing an optical pattern 2 for measuring displacement is provided movably for the main body (e.g. a governor) 1 of an apparatus for inflammable gas so that it corresponds to a displacement member 4(16, 17) of the main body 1, while a light- transmitting elements 5a and a photosensing element 5b for measuring displacement are provided corresponding to the scale 3. The light-transmitting element 5a and the photosensing element 5b are connected to the main body 6 of a detector constructed remote from the main body 1 by optical fibers 7a and 7b. A light from the main body 6 passes through the fiber 7a and is projected from the light-transmitting element 5a onto the pattern 2 of the scale 3, and a transmitted light or a reflected light therefrom is received through the photosensing element 5b and the fiber 7b. When the displacement member 4 is displaced, the scale 3 is also displaced and the photosensitivity for the transmitted light and the like of the pattern 2 is varied. Therefore, the displacement of the displacement member 4 can be detected sequentially by detecting and processing the variation in the main body.

Title: Sedimentation tank for cleaning pigment and method for cleaning and settling pigment
Inventor: TAKANO KEIICHI
IPC: C02F1/52
Filed: 1988-08-29
Abstract: PURPOSE:To simultaneously and efficiently remove the impurities and fine particles in waste liq. by changing the liq. discharge position as the height of the liq. surface changes due to the liq. discharge, and discharging a cleaning solvent always from the upper end of the liq. when the liq. is discharged. CONSTITUTION:A slit cover 4 is fixed to a liq. discharge slit 3 on the side face of a columnar tank 1. An org. photosensitive material and cleaning solvent are charged into the tank 1, and then an agitating rod 2 provided with an impeller is rotated. The liq. agitation is stopped, and the pigment is settled. The cover 4 is then moved in the direction (a), and the solvent is discharged from the slit 3. The process is repeated several times, a valve 5 is opened, and the pigment is discharged from a discharge pipe 6. The liq. discharge position is changed as the height of the liq. surfaces changes due to the liq. discharge to discharge the solvent always from the upper end of the liq., and the redispersion of the settled pigment due to the turbulent flow caused by the liq. discharge can be prevented. By this method, the impurities and fine particles in the waste liq. can be simultaneously and efficiently removed in the high yield of pigment.

IPC: F16K31/04
Filed: 1991-07-31
Abstract: PURPOSE:To improve durability in a screw mechanism by giving output pressure of a motor-driven pilot pressure control valve to a pressure governing piston so as to move the pressure governing piston. CONSTITUTION:Under a condition that a spring bearing 62 of a motor-driven pilot pressure control valve 41 is on the rightward movement final edge and pressure is set according to the lowest spring force of the first/the second pressure governing springs 31 and 32 in a pilot valve 27, an electric motor 56 is rotated in one direction by a prescribed quantity. Thereby, the spring bearing 62 moves leftward by a prescribed distance, and the second pressure governing spring 53 is deflected, so that spring force is increased. Thereby, pressure of an entrance chamber 47 in the electrically driven pilot pressure control valve 41 is heightened by the extent that the spring force of the second pressure governing spring 53 is increased. This pressure acts on a pressure governing piston 37 through a pressure governing chamber 38, and moves the piston leftward while deflecting the pressure governing springs 31 and 32 until it can be balanced with the spring force. Thereby, pressure of an entrance chamber 28 in the pilot relief valve 27 is heightened due to the increased spring force of the pressure governing springs 31 and 32.
