Title: Printing equipment
Inventor: ENDOU MASAKAZU
IPC: B41J25/316
Filed: 1984-06-01
Abstract: PURPOSE:To prevent the generation of jamming by driving a print head with an operation member before a conveying roller to separate the print head from the platen ahead thereof so that a recording paper is conveyed and set with the conveying roller. CONSTITUTION:After a lever 12 is turned by a certain angle, an inclined surface S is provided to press a shaft 15 in contact therewith to separate. At the first position where the lever 12 is turned by a certain angle, a convex part 13 displaces a link rod 9 to isolate a print head 1 from the platen 5 so that a conveying roller 14 is pressed against the platen 5. When the lever 12 is further turned to the second position, the inclined surface S isolates the conveying roller 14 from the platen 5 and the print head 1 and the conveying roller 14 are isolated therefrom to facilitate the correction of the position of a recording paper.

Title: Light rolling reduction casting method
Inventor: MASAOKA TOSHIO
IPC: B22D11/12
Filed: 1987-05-12
Abstract: PURPOSE:To reduce center segregation of a cast slab and to improve quality by dividing multiple pairs of rolls executing light rolling reduction to the non-solidified cast slab, measuring rolling reaction received from the cast slab and adjusting the roll reduction rate and cooling water injection rate, so as to come to the specific strain speed by grasping the strain speed of the cast slab. CONSTITUTION:At the time of applying the light rolling reduction at suitable strain speed to the cast slab 30 at the end time of solidification, the reaction (b) is acted to the divided roll 16b. The roll 16b is pushed by the cast slab 30 and detecting part of a measuring instrument 39b is deformed and the resistant value of the detecting part is changed, to generate current. This current is converted into voltage signal and inputted to a storing part of CPU40 and based on the input data of the reaction (b), the strain speed of the cast slab is calculated as a parameter. Then, the parameter is compared with the prescribed suitable strain speed and the difference is transmitted to a hydraulic control device 42 as the voltage signal. Then, the different signal is transmitted to a cooling water control device 44, too, to adjust the spray water rate injected to the divided roll 16b, so that the different signal comes to zero. Further, the reducing the rolling reduction rate of the roll 16b, the reaction (b) is relaxed, and by making the strain speed of the cast slab 30 at the suitable speed, flowing of the molten steel in the internal part of the cast slab 30 is prevented and the center segregation is reduced.

Title: Continuous jet type ink jet recording apparatus
Inventor: MUTO MASAYUKI
IPC: B41J2/045
Filed: 1994-04-28
Abstract: PURPOSE:To correct the delay of a recording ink particle row caused by air resistance depending on a dot size and record a dot at a specific position regardless of a dot size. CONSTITUTION:A pulse width modulator PWM outputs a charge control signal Sc having the pulse width corresponding to the value of pixel density data Dp in synchronous relation to an encoder clock fE and a data converter DC outputs data DA obtained by converting the pixel density data Dp in synchronous relation to the encoder clock fE. A D/A converter (negative) DAN converts the data DA only when the PWM signal Sc is active to output a charge correction signal phiA. A high voltage switch HVS applies charge control voltage (phic+phiA) wherein the charge correction signal phiA is superposed on a charge control signal phic obtained by converting the PWM signal S to high voltage to a control electrode 4. As a result, the recording ink particle row emitted from a nozzle 1 is deflected toward a deflection electrode 8 in a pixel unit corresponding to the piexel density data Dp and the delay of the recording ink particle row due to air resistance is corrected.

IPC: B65H29/40
Filed: 1996-05-08
Abstract: PROBLEM TO BE SOLVED: To reduce useless power consumption by controlling the rotating speed of one stacking impeller in a stacking state between two stacking impellers to the specified high speed rotating speed, and controlling the rotating speed of the other stacking impeller in a stand-by state to the specified low speed rotating speed. SOLUTION: Two stacking impellers 41a, 41b are rotatory-driven by stepping motors 42a, 42b through a belt. The stepping motors 42a, 42b are driven by motor drivers 103a, 103b through impeller controllers 102a, 102b. In this case, the rotating speed of one impeller between two alternately operated stacking impellers 41a, 41b is set to the specified high speed rotating speed, and the rotating speed of the other impeller put in a stand-by state is set to the specified low speed rotating speed. Since the rotating speed at the stepping motor 42a or 42b for driving the impeller in the stand-by state is made lower than the rotating speed at the time of stacking, useless power consumption is positively reduced by that part.

Filed: 1979-09-05
Abstract: PURPOSE: To prevent the separation phenomenon of a molding flask and sand from a pattern plate by performing jolting by the impact owing to the gravity fall of a jolting table at the prejolting.  
     CONSTITUTION: When a jolt hammer 12 is moved upward by supplying pressure air through an air feed and exhaust hole 16 and the pressure air is fed through an air feed hole 14, a jolting table 13, a pattern plate 20 and a sand falsk 21 packed with sand 22 move upward on one piece. When the exhaust hole 15 of the table 13 comes above the top of the hammer 12, the compressed air in the hollow part 23 is exhausted through the exhaust hole 15. Thereupon, the table 13 descends again until its bottom 13b collides against the shoulder top 12a of the hammer 12. At this time, the table 13 as well as the pattern plate 20, sand 22, sand flask 21, etc. are pressed to a stopper 19 by the compressed air, so that impact is given to the hammer 12. The sand flask 21 and the sand 22 collide with a downward velocity and the formation of a clearance between the pattern plate 20 and the sand flask 21 is prevented by the inertia thereof.

Abstract: PURPOSE: To produce a classifier with an excellent separating property for solids in suspension by installing side plates, an upper water flow checking plate, a lower water flow checking plate, and a cross partition plate to the accelerator of a drum type plassifier.  
     CONSTITUTION: The settling accelerator of a drum type classifier is constituted by a pair of side plates 19 arranged in parallel with the axial line of the drum, an upper water flow checking plate 20 attached to the one end of the side plates 19 to guide raw water into the bottom, a lower water flow checking plate 21 attached to the other end of the side plates 19, and a cross partition plate 22 attached between the side plates 19 so as to intersect the side plates 19. Raw water supplied to the drum flows under the drum and then rises up through the cross partition plate 22. Since the water flow around the bottom of the drum is checked by the lower water flow checking plate 21, only the upper water flows into a discharge hole. Thus, water flows from the bottom to the surface, separating the solids from suspension effectively.
