Title: Ultraviolet-curable ink
Inventor: OSATO MITSUO
IPC: C09D11/02
Filed: 1988-06-17
Abstract: PURPOSE:To obtain the title ink which has a markedly increased curing rate and can give printed matter free of offset and discoloration of paper itself by adding a fine powder of an acrylic resin to an ultraviolet-curing ink. CONSTITUTION:2-5wt.% fine acrylic resin powder (surfactant-free fine (0.2-0.5mum) acrylic resin powder prepared by the soap-free emulsion polymerization process) is added to 100wt.% ultraviolet-curable ink. Because of the improved curability of the ink, it is not necessary to increase the intensity and time of irradiation of ultraviolet rays in printing, and good printed matter free of offset and discoloration of paper itself can be obtained. The efficiency of printing work can be improved because the printing speed can be heightened.

Filed: 1995-06-16
Abstract: PURPOSE: To produce a double oriented silicon steel sheet excellent in magnetic properties.

Title: Pipe joint
Inventor: SHIMADA HARUMI
IPC: F16L37/12
Filed: 1990-06-07
Abstract: PURPOSE:To obtain a pipe joint which is hardly spoiled on its surface when torque acts onto piping by forming a sliding face between an annular locking means and a supporting member to make their mutual relative rotation possible. CONSTITUTION:An annular locking means 4 is composed of a locking ring 41 and a receiving ring 4 fitted on the outside of the ring 41. A supporting member 5 is composed of a spacer 51 and a collar 52 which sandwichedly hold the means 4 from its axial front and back sides. The outer end face 51a on the side of the means 4 of the spacer 51 is provided with a notched part 51b so that the open end 42a of the receiving ring 42 may fit slidably in a rotational direction to make free relative rotation between the both elements possible. The outer periphery of the receiving ring 42 is formed somewhat smaller in comparison with the inner wall 3 of a main body 1 opposite to the ring 42, and sliding faces 42b, 52b between the ring 42 and the collar 52 are formed as a gliding face so as to make smooth relative rotation possible. Thus, when torque acts onto piping 6, relative rotation does not occur between a locking claw 41a and the piping 6, and the surface of the piping 6 is therefore hardly damaged.

Title: Multi-microprocessor system
Inventor: SAKURAI AKIHITO
IPC: G06F15/16
Filed: 1985-07-10
Abstract: PURPOSE:To enable plural microprocessors to share a peripheral device control circuit IOC by providing a pseudo interruption generating circuit to transmit an interruption signal given from the IOC and making other processors use the IOC. CONSTITUTION:A microprocessor 21 has a request to use an IOC 15 and a microprocessor 11 approves this request. Then the processor 11 sets an interruption code corresponding to the interruption of the IOC 15 to an idle one of registers 51-5n in the pseudo interruption generating circuit 1. Hereafter the processor 11 has no working to the interruption given from the IOC 15. Thus the interruption given from the IOC 15 is sent to the processor 21. While the processor 11 neglects this interruption and therefore has not corresponding working.

     CONSTITUTION: The catalytic reaction under pressure is conducted by supplying a mixture of an alcohol containing a metal catalyst in platinum group and a nitrite ester from pipe 12 and a gas containing carbon monoxide and oxygen from pipe 13 to reactor 1. The reaction product is introduced through pipe 16 into dehy- dration column 2 where warter formed is distilled off as an azeotropic mixture with the nitrite ester. Then it is separated in separator 3 and the nitrite ester is recycled to dehydrator 2 and the water is taken out of pipe 20. In the present process effective dehydration is conducted and the formation of by-products is inhibited. When the waste gas contains a small amount of the alcohol and nitrite ester, it may be cooled to condense them, which are reused. Then a part of the dehydrated product is circulated through pipe 27 and the oxalic ester is obtained from pipe 26.

On the other hand, if the cathode 15 is put in negative potential with respect to the  anode 16, the positive ions in the plasma become ion beams 20 from a beam takeout port 19 and collide against the material 23 to be etched. The hydrogen molecules admitted into a preliminary chamber 27 are dissociated to active hydrogen  atoms by a tungsten filament 28 and stick on the material 23 to be etched.
