Title: Method for manufacturing highly anti-corrosion alloy clad steel plate having no carburizing at surface of cladding metal
Inventor: BABA YUKIHIKO
IPC: B32B15/01
Filed: 1980-12-26
Abstract: PURPOSE:To manufacture highly anti-corrosion alloy clad steel plates having no carburizings at the surface of the cladding metal, by performing a close welding on four sides of the contact surface of a cladding metal and another cladding metal, and also performing the close welding on four sides of the whole combined flanks. CONSTITUTION:To prepare a sandwich type combined plate, a cladding metal 12 is put on a base metal 11, and another cladding metal 12' is put on the cladding metal 12 with a separating agent 13 between them. Then, another base metal 11' is put on the cladding metal 12'. After they are combined in this way, four sides of the contact surface of the cladding metals 12 and 12', in which the separating agent exists, are close welded at a welding part 16. After the close welding is made, four sides of the whole combined blanks are close welded at a welding part 15. The sandwich type combined blanks formed in this way is subjected to a rolling after heating, and thus, two sets of clad steel plates are manufactured.

Title: Tool clamper
Inventor: SATO SANEJI
IPC: B23B31/117
Filed: 1984-09-03
Abstract: PURPOSE:To aim at miniaturization in a tool clamper as well as to improve the dynamic balance of a spindle ever so better, by reducing the number of Belleville springs to be attached to a collect shaft in a state of being layered. CONSTITUTION:A collect shaft 13 is set up inside a spindle 12, while a collet and a collet keep bush 17 are set up free of relative rotation with each other. And, in this collet keep bush 17, there is provided with a concave part 17 so as to make a tip part 14a of the collet enterable. Accordingly, in this clamper, since opening or closing motion in this collet is obtainable out of the relative rotational motion between the collet 14 and the collet keep bush 17, it is unnecessary to move the collet 14 in the axial direction. Therefore, Belleville springs attached to the collet shaft 13 are enough to merely receive pressing force as far as only releasing the clamping force exerted on the collet 14 so that the number of these Belleville springs 19 is sharply reducible.

Title: Document feeder
Inventor: KUBOTA KAZUNORI
IPC: G03G15/00
Filed: 1982-10-20
Abstract: PURPOSE:To reliably convey a document without the occurrence of bending of the forward end of the document even if it is thin, by regulating the tension of a conveying belt, running around a drive roller and a driven rollers, according to the thickness of the document. CONSTITUTION:During ordinary operation, a solenoid 14, forming a document thickness setter 15, is brought in an OFF-state together with a switch 13, a distance between the shaft of a drive roller 2 and that of a driven roller 3 is held at a value l, and a slack is left on a document conveying surface 4a of a conveying belt 4. With this, a thick document is conveyed. Meanwhile, when the document is thin, the switch 13 is closed to turn ON the solenoid 14 to attract a lever shaft 12. This causes a lever 10 to be rotated centering around a support shaft 9 to move a shaft 7 rightwardly along an oblong hole 8, and a distance between said shafts is set to an increased value l+DELTAl. This reduces the amount of the slack left on the document conveying surface 4a of a conveying belt 4, and reduction in its conveying force results in prevention of the occurrence of bending of the forward end of the document due to collision with a stop claw 5.

Title: Sublimating thermal transfer image acceptor
Inventor: SATO KOJI
IPC: B41M5/52
Filed: 1987-07-23
Abstract: PURPOSE:To prevent a recording image from causing transfer omission, by laminating successively an elastic layer and a special image accepting layer on a base material. CONSTITUTION:An elastic layer 32 is provided on a base material 31 and further, an image accepting layer 33 capable of heat transfer recording by using a thermal transfer sheet containing sublimating dye is provided thereon. When the elastic layer exists, the elastic layer portion can be deformed according to minute unevenness of a head and a sample base against application of recording pressure. Therefore, contact unevenness of a head to a medium can be greatly removed, and a recording image can be prevented from omission or the like. Rubber state substance is suitable as material of the elastic layer, and its thickness is preferably within a range of 3-20mum rather than 1-30mum. Thickness under 1mum causes shortage in effect of the elastic layer. Further, when the thickness exceeds 30mum, undulation or the like of the surface become remarkable and recording unevenness will be brought about.

This uniform fluid is extruded or cast to the membrane and the membrane is passed through such >=1 zone where the membrane solidifies, by which the membrane is rapidly cooled or solidified. The membrane is then passed through >=1 zone where at least the substantial portion of the solvent may be removed from the membrane. The membrane is thereafter leached simultaneously or in succession thereto, by which the thin semipermeable membrane having the isotropic or anisotropic syndiotactic polystyrene microporous structure is formed. The semipermeable membrane having the form of hollow fibers is more adequate.
