IPC: B27F7/02
Filed: 1992-04-02
Abstract: PURPOSE:To increase unifying force of a plate material with a frame body by preventing a nail from projecting from the frame body owing to bend of the nail with a conventional nailing machine by a method wherein a nail-driving in direction is made changeable in the nailing machine which drives automatically the nail to be drawn out into the frame body. CONSTITUTION:A roller 31 of a frame moves to a position 31a along a cam groove 29 when a piston rod of one side cylinder advances leftward. Therefore, a nailing machine 9b comes to be inclined to a position 9b1 of a two-dot chain line as a whole, and a nail-driving in direction B comes to be inclined by an angle theta1 from the perpendicular direction A. Besides, when another cylinder of the dual cylinder is actuated and the piston rod moves back relatively, the roller 31 is moved to a position 31b thereby. Therefore, the nailing machine 9b is inclined to a position 9b2 of the two-dot chain line, and the nail-driving in direction C comes to be of a state of being inclined by an angle theta2 on an opposed side to the angle theta1.

Title: Ink-jet printer
Inventor: TANII KEIICHI
IPC: B41J2/085
Filed: 1995-05-25
Abstract: PURPOSE: To obtain a SWEET type ink-jet printer that can prevent a recording paper from being stained when ink pressure are increased or reduced at the start-up or completion time of ink spouting without giving a limitation to a nozzle as an addition of a mechanism such as a valve. CONSTITUTION: Before pressure is increased or reduced, the direction of the electric field between deflecting electrodes 8a and 8b is reversed, and then a negative charge is given to an ink drop. Thereby the ink drop is turned inversely to the direction at the time of image drawing, causing the ink drop to be caught deeper inside a gutter 11. In this state, pressure increase or reduction operation takes place. Therefore, the enervated ink drop is further deflected downward by the magmetic field and jumps over the gutter 11, so that the ink drop does not reach and taint the recording paper at the time of start-up or completion of image drawing.

Title: Preparation of concentrate of titanium dioxide useful as raw material for chlorinaton in fluidized bed
Inventor: ADACHI MASAAKI
IPC: C01G23/047
Filed: 1980-09-12
Abstract: PURPOSE: To make the carry-over of impurities in fluided bed chlorination, easy, and to stabilize the fluidized bed for a long time, by grinding ilmenite into finely divided powder under given coditions, before it is leached with an acid and concentrated to the desired high quality.  
     CONSTITUTION: Ilmenite produced from a bulky mineral deposit is ground into powder wherein ≥80wt% passes through a sieve with a 200 mesh. The finely divided powder is leached with a mineral acid, and iron is removed to give a powdery titanium concentrate having a TiO 2  quality of ≥90%. A small amount of water is added to the concentrate, which is compression molded, and ground to give granulates having 10W150 mesh and high strength. Though a large amount of silica which is not removed by leaching treatment is contained in the concentrate, it is subjected to carry-oven in the fluidized bed chlorination since it is ground into powder, and the silica is not accumulated in the chlorination furnace. Consequently, the fluidized bed is stabilized for a long time.
