Filed: 1978-11-17
Abstract: PURPOSE: To inhibit oxygen absorption of molten metal in the mold and obviate the formation of Cu-Cu 2 O eutectic layer on copper wire bar surface by puring molten copper into a horizontal boat type mold then spraying a dilute surfactant solution prior to solidification.  
     CONSTITUTION: A water spray pipe 6 arrayed with water spray holes 5 is installed rotatably between the upper position and lateral position of the opening face of a horizontal boat type mold 7. At the time when pouring of molten copper 8 is finished, the water spray pipe 6 is moved over the opening face of the mold 7 and before the molten metal solidifies completely, a dilute solution 9 of soap such as sodium laurate, etc. or anionic surfactants such as sodium alkyl benezene sulfonate, etc. is sprayed from the water spray pipe 6. This dilute surfactant solution is quickly adsorbed on the molten metal surface to cut off the molten metal surface from the atmospheric air and effectively prevent the oxygen absorption of the molten copper in the mold 7 and therefore the formation of Cu-Cu 2 O eutectic layer becomes less.

Title: Manufacture of ink-jet head
Inventor: YASUHARA MASATOSHI
IPC: B41J2/045
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To facilitate management of a movement locus and realize highly accurate processing, by processing an ink pressure groove with the use of a circular dicing blade while moving a head substrate or the dicing blade linearly. SOLUTION: In order to manufacture an ink pressure groove of a head substrate, an up-down mechanism part is driven at a predetermined position in XY directions calculated from a reference position, thereby lowering a dicing blade 15 in a Z direction. An upper face of a part to be processed (head substrate) 18 fixed on a fixing ring 20 is accordingly cut to a predetermined depth of an ink pressure chamber. Thereafter, an X-directional movement mechanism part is driven to move and process the part 18 in a direction parallel to the X direction by a length of the ink pressure chamber. The dicing blade 15 is raised then in the Z direction, and a blade mount part 16 is driven to move a position of the blade by a pitch of the groove. The same process is carried out afterwards, so that the ink pressure groove is processed at a position separated by a predetermined pitch. The process is repeated by a count of grooves, whereby an ink-jet head is obtained.

Filed: 1983-08-03
Abstract: PURPOSE:To reduce the titled device in its size by receiving parallel light projected from a lens by the 1st mirror out of a pair of mirrors to reflect the parallel light in the reverse direction and then receiving the light by the 2nd mirror to return the light in the advancing direction again and guide the light to a mirror opposed to a photosensitive drum. CONSTITUTION:Light projected from an exposure lamp 6 irradiates the surface of an original 4 and the light reflected from a point (a) is refracted by a reflecting point (b) on a mirror 9, a reflecting point (c) on a mirror 10 and a reflecting point (d) on a mirror 11 respectively, guided downwards and made to reach the lens 8 and optical length l1 is formed at the front half of the lens 8. The light passing through the center point (e) of the lens 8 is made incident on a mirror 22, reflected by the mirror 22 at a reflecting point (f) in the reverse direction, reflected by a mirror 23 at a reflecting point (g) and projected by a mirror 12 from a reflecting point (h) in the direction of a drum 13 and optical length l2 is formed. Since a pair of mirrors 22, 23 are arranged in proximity to the mirror 12, the distance from the lens 8 to the mirror 12 can be shortened without shortening the optical length l2 and the device can be reduced in size without changing the designed structure of the copying machine sharply.

Title: Roll flaw detecting method
Inventor: ITO NOBUAKI
IPC: B21B28/00
Filed: 1994-06-24
Abstract: PURPOSE:To enable flaw detection on the whole surface of a roll efficiently and correctly by shifting the phase in the circumferential direction of a roll corresponding to a flaw detectable width at every path by plural pulses of finishing to perform flaw detection. CONSTITUTION:When flaw detection is made once round a roll in the axial direction of the roll at the final one path, flaw detection is made at certain intervals of the flaw detectable width. Accordingly, if the phase of the next second path is controlled to be shifted, the nest phase to flaw detection on the first orbit is subjected to flaw detection. Further, a part not subjected to flaw detection is again shifted in phase, and flaw detection at the third path is made in the circumferential direction of the roll. thus, when the final plural paths in the whole N-paths of finishing are subjected to flaw detection while the maximum feed speed determined by the flaw detectable width is taken and the phase in the circumferential direction of the roll is controlled to be shifted corresponding to the flaw detectable width at each path, flaw detection for the whole surface of the roll can be accomplished after N-paths. Thus, flaw detection for the whole surface of the roll can be completed simultaneously with finishing.
