Title: Method and apparatus for controlling ph in water-purifying plant
Inventor: SUZUKI NORIHISA
IPC: C02F1/52
Filed: 1981-09-25
Abstract: PURPOSE:To suppress the formation of trihalomethane, by adding an acid to raw water to lower pH below the first estimated value, injecting chlorine, and then injecting an alkali agent to raise pH above the second estimated value before the addition of a flocculant. CONSTITUTION:A pH value (e.g. pH below 5) is set by a pH-setting instrument 12 to enlarge a pasteurizing effect while suppressing the formation of trihalomethane in raw water. Said value and a value from a pH meter 11 for the raw water are inputted into an arithmetic circuit 13 for calculating an amount of sulfuric acid to be injected. On the basis of the calculation result, sulfuric acid is injected to adjust pH of the raw water in a water-collecting well 1. A fixed amount of chlorine is then injected from a chlorine injector 7. A pH value at the point of injecting a flocculant is calculated from the pH of the raw water, the amount of injected sulfuric acid and the amount of injected chlorine by an arithmetic circuit 15 for calculating an amount of an alkali agent to be injected. The alkali agent is injected from a means 10 in response to a difference between said calculated pH value and a pH value from an instrument 14 for setting pH of coagulated water.

Title: Sealed lead accumulator
Inventor: YOSHINAKA MINORU
IPC: H01M50/543
Filed: 1987-06-17
Abstract: PURPOSE:To suppress generation of burrs at fusion deposited parts of an armor case formed through fusion deposition of a metal plate and a frame by making the fusion deposition part of the frame with a specific profile. CONSTITUTION:An armor case is formed from two metal plates 6 sandwiching a group of pole plates and a frame 4 formed around these metal plates 6. The frame 4 is made of synthetic resin of polyolefin type, and this resin is hot deposited to the laminated metal plates 6. The section of frame 4 in its fusion deposited part has a rib with higher bore than the periphery, and the tip of this rib is tapered in such a way as increasing the height toward the side away. Thereby burrs 12 at the time of hot deposition do not extrude the outer corner which the metal plate 6 and frame 4 constitute. This provides near contour to prevent breakage when it is covered with a thermo-shrinking tube, that should prevent shortcircuiting.

Abstract: PURPOSE:To manufacture a resin-made flexographic plate which has superior resolving power and endless constitution by exposing an image formation layer on a light-setting resin sleeve plate to a laser beam with scanning system and thus forming an image, and then printing the image, and developing its latent image. CONSTITUTION:On a metallic cylinder 10, light-setting resin 14 is formed and  onto it, a thin-film image formation layer 16 is formed. A base 12 is coated  with the light-setting resin 14 with an adhesive layer 13 interposed. This plate is  scanned with a laser beam. This laser beam is generated favoraly by an argon  or YAG laser, etc. In this scanning exposure, a film part which corresponds to  a positive image of original image lines are destroyed and blown away. The plate given the image is printed. This printing sets light-setting resin at a part  18 irradiated with light to form a latent image, and a part 20 which is not  irradiate with the light because it is covered with the image formation layer 16  is left as it is unset. Then, the plate is treated by development. Then, the plate  is treated by postprocessing such as drying and post-development to perform  flexographic printing.
