Title: Washing apparatus
Inventor: TAKAHASHI KAZUMI
IPC: F16L23/02
Filed: 1993-10-14
Abstract: PURPOSE:To inexpensively stabilize the hermetical close degree between washing tanks even against a manufacturing error or thermal deformation by fixing one surface of the first member of the connection components of the washing tanks to the wall surface of one washing tank through a first elastomer and connecting the other surface thereof to the other washing tank by the second and third members being in contact with the connection components of the tanks and a second elastomer. CONSTITUTION:Washing tanks 1, 2 are assembled at a constant position. At this time, the positional relation between the washing tanks 1, 2 is different from the aspect of planning because there is a dimensional error in the washing tanks 1, 2 and there is also an error from the aspect of assembling. Therefore, the gap 4 between the washing tanks 1, 2 is not constant and a stepped part is generated between the flange part leading end of the connection component 7 of the tanks and a wall surface. Since the part on the side of the washing tank 1 is divided into a part 6 smaller than the flange part of the component 7 and a part 5 to which a hole slightly larger than the hole of the washing tank 1 is formed, even when the leading end surface of the flange part of the component 7 and the wall surface 3 are not same, a rubber packing 8 expands and contracts and respective constituent components can be always brought to a close contact state.

Title: Shearing die assembly
Inventor: YOKOYAMA MITSUMASA
IPC: B23D35/00
Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To prevent a clearance from becoming smaller than a prescribed quantity, and to thereby prevent cutting blades of a pushing blade and a receiving blade from being contacted, abraded and damaged, by installing, on the pushing blade or the receiving blade, a clearance retaining member for retaining the clearance between the pushing blade and the receiving blade at a prescribed quantity. SOLUTION: At the time of shearing the end of a long angle steel product 31, if a pushing blade 23 is pushed down in the state where the angle steel product 31 is set obliquely on an angle cutter die assembly 12, the pushing blade 23 is pushed toward the one receiving blade 17 side and the pushing blade 23 is apt to fall obliquely, but as a projecting part 23a of the pushing blade 23 is brought into face contact with the receiving blade 17, a cutting blade 23c of the pushing blade 23 is not contacted with the receiving blade 17, and shearing is executed by utilizing the projection quantity of the projecting part 23a as a clearance. A proper clearance is always kept, and stable shearing can be executed without generation of a scoring wear or a crack.  And besides, the clearance on the receiving blade 17 side does not become larger than required by a projecting part 23b, and burr generation on the shearing face can be prevented.

IPC: H04N5/357
Filed: 1989-10-03
Abstract: PURPOSE:To improve the defect of charge transfer and to improve picture quality by providing a control means in a solid-state image pickup element to simultaneously transfer charges, which are transferred by plural vertical transferring means, to plural horizontal transferring means and transferring the charges, which are transferred by the plural vertical transferring means, in various directions. CONSTITUTION:When driving pulses phi1-phi4 are successively inputted from a pulse driving circuit 12 to the respective transfer electrodes of vertical CCD V1-V5, the charge which exists in the transfer electrode of the vertical CCD V1 is transferred to a horizontal CCD H1, which is arranged in a lower direction, since the transfer electrodes are crossed and connected. On the other hand, the charge which exists in the transfer electrode of the vertical CCD V2 is transferred to a horizontal CCD H3, which is arranged in an upper direction, by the driving pulses phi1-phi4. Samely, the charges of the vertical CCD excepting for the above mentioned vertical CCD are also simultaneously transferred to the horizontal CCD for every four columns. Accordingly, distances for transferring the charges from the plural vertical CCD to the most distant horizontal CCD is made short and the defect of the charge transfer can be widely improved.
