Title: Apparatus for controlling flow rate of sewage
Inventor: KITAO TAKANE
IPC: G05D9/00
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To average the flowing amt. of sewage by varying the ratio of the outflow amt. of sewage to the inflow amt. thereof by simple constitution. SOLUTION: A storage tank 2 is demarcated by first and second partition walls 4, 10 to form an anaerobic tank 5 and an aerobic tank 6 and a sedimentation tank 11. A disinfection tank 13 is demarcated at the upper part of the sedimentation tank 11 by a wall part 14 formed so as to enable sewage 3 to overflow the sedimentation tank 11. A raw water pipe 7 allowing sewage 3 to flow in is connected to the anaerobic tank 5 and a discharge pipe 19 is connected to the disinfection tank 13.  A small hole like communication hole 16 of the max. flow amt. almost small to the day average flow rate of the sewage flowing into the storage tank 2 is formed to the wall part 14 and, when sewage 3 flows in an amt. less than the max. flowing amt. of the communication hole, sewage passes through the communication hole from the sedimentation tank 11 while it is subjected to purifying treatment in the anaerobic and aerobic tanks 5, 6 to flow in the disinfection tank 13. When sewage 3 flows in an amt. more than the max. flowing amt. of the communication hole, the water level in the storage tank 2 to be stagnated in the sedimentation tank 11 to be delayed in its flow rate to be allowed to overflow the wall part 14. An outflow amt. is averaged.

Title: Two-dimensional and three-dimensional change-over device of transfer feeder
Inventor: MATSUSHITA KEIJI
IPC: B21D43/05
Filed: 1979-02-19
Abstract: PURPOSE:To make possible the two-dimensional and three-dimensional changing- over of the feed bar, simplify constitution and reduce size and weight by selecting the revolutions of a drive system to an equal speed and an unequal speed by a clutch means. CONSTITUTION:In the case of letting a feed bar 33 make three-dimensional operation, a jaw clutch 6 is moved downward by an operating handle 8, by which the revolution of a drive shaft 3 is transmitted to a drive gear 5, by which the housing 12a of an unequal speed mechanism 12 is revolved. As a result, the dwell in the return end and advance end becomes wider than that of equal speed revolutions and the three-dimensional motion of the feed bar 33 becomes feasible. On the other hand, in the case of changing-over the feed bar 33 to two-dimensional operation, the jaw clutch 6 is moved upward and since this causes the revolution of the drive shaft 3 to revolve gears 19 and 20 at an equal speed, the feed stroke suited for the two-dimensional operation of the feed bar 33 becomes obtainable for the feed stroke of the feed bar 33.

Abstract: PURPOSE:To keep a fish preserve in stable posture and to facilitate the control of the depth of the fish preserve, by disposing an integrated sinking and floating member in a fish preserve frame independent of the frame and sinking or floating the fish preserve frame by varying the weight or buoyancy of the sinking and floating member. CONSTITUTION:Water is supplied to a sinking and floating member 5 through a pipe 6 by a supplying means such as pump. When the amount of water supplied to the member is increased, the member 5 loses excess buoyancy and begins to sink. The vertical downward component of the force of an anchoring rope 9 is applied to the fish preserve frame 1 around the rope-supporting member 2 to effect the sinking of the main body of the fish preserve. When the fish preserve is to be floated, compressed air is supplied to the sinking and floating member 5 through a pipe 7 to discharge sea water from the member through the pipe 6.
