    Abstract: PURPOSE: To uniformize the areas or depths of processed predetermined repeating patterns by stepwise sending a work by the integral multiple of the pitch of the predetermined repeating patterns when the predetermined repeating patterns are formed on the work through a mask by using a laser oscillator as a light source. CONSTITUTION: When a large number of orifices 16 are formed to an orifice plate (work) 15 of an ink jet recording head, predetermined pulse irradiation is performed by one laser irradiation due to a laser oscillator. At each time when this irradiation is completed, the work 15 is stepwise sent by one pitch by a stage 11 to be further irradiated with laser beam. By repeating this step many times, pierced orifices 16... and non-pierced holes 21... are successively formed. At this time, when the non-pierced holes 21 are not provided to both ends of the orifice plate 15, a mask shutter 17 fitted with a movable mechanism is used and laser irradiation is performed while the hole patterns of a mask 13 are successively covered.

    Abstract: PURPOSE:To stabilize the quantity of discharge of ink from the early stage by reducing a change of the quantity of the discharge of the ink at every one time discharge. CONSTITUTION:A marking-off groove 9 is formed in the surface of a heating energy generating part 10 including a heating resistor layer 5 to generate heat energy which is used for discharge of ink along an isothermal line of a heating temperature distribution of the heat energy generating part 10. Since the marking-off groove 9 is formed, the marking groove itself acted upon as a forming core and a quantity of discharge of the ink is stabilized from the beginning stage.

    Abstract: PURPOSE:To provide a work transfer method capable of shortening a tact time of an assembly device while preventing the cost of the assembly device from increasing. CONSTITUTION:In a work transfer method in which an operation to transfer an incomplete work B from a pallet 27 which transfers works B and B' onto a specified assembly device and an operation to transfer a complete work B' from the assembly device onto the pallet 27 are made by one transfer device, the transfer device is provided with at least a first holding section 73a for holding the incomplete work B and a second holding section 73b for holding the complete work B'. Then an operation to hold the incomplete work B on the pallet 27 by the first holding section 73a and an operation to place the complete work B' on the pallet 27 by the second holding section 73b are made simultaneously.

    Abstract: PURPOSE:To provide an article assembling method in a process-divided assembling device which can reduce a process time for intermittent operation and improve productivity even if a process is divided into a plurality of work stations so as to assemble one article. CONSTITUTION:A position of a heater board is measured by a first ITV camera 30 in a first process, and while the heater board is moved from a second work station 18 to a third work station 20 based on a measured result of the first ITV camera, a position of a second ITV camera 36 is moved to a position optimum for measuring a position of a top board, and a position adjusting mechanism 38 is moved to a position optimum for position adjustment for the top board for the heater board.

    Abstract: PURPOSE:To prevent the relative dislocation by temporarily bonding a top board member onto a heater board by an adhesive, and fixing temporarily both bonded members onto a board through a spring member, and setting the position of adhesive application apart from the fixing position. CONSTITUTION:A top board member 104, where nozzle holes corresponding to each heater are made, is placed on a heater board 102, where a plurality of heaters for ink heating are made, and adhesives 80a and 80b are applied on one of them, and each other's adhesive faces are temporarily boded. The temporarily bonded heater board 102 and the top board member 104 are fixed firmly onto the board with a spring member 122 for fixation. At this time, the top board 104 and the heater board 102 are positioned relatively with a positioning mechanism. Moreover, the right and left feet 112a and 112b of the spring member 122 are inserted into the mounting hole 208c of the base member 208, in close vicinity to both side margins of the heater board 102. And the application areas of the adhesives 80a and 80b are set apart from the heater arranged region, so the adhesion is not marred, and the dislocation is prevented.

    Abstract: PURPOSE:To adhere a top plate to a heater board in a short time by applying an ultraviolet hardening adhesive to between the top plate member and the heater board, and providing an ultraviolet ray passing hole in that place on a finger which mates with the adhesive applying position. CONSTITUTION:A pair of suction members 26b, 26c as finger to grasp the top plate are installed at the foremost of the body 26a of a mounting mechanism 26, and a suction holes are opened in the under-surfaces of these suction members 26b, 26c'. The communication pipes penetrating the suction members 26b, 26c are connected with a negative pressure generating mechanism and a positive pressure generating mechanism selectively via respective selector valves, and hold the top plate sucked to the under-surfaces of the suction members 26b, 26c or pull the plate away from them. In each suction member 26b, 26c, a hole 57 is formed whose one end is open at the under-surface to the adhesive applying position and while other end is open at the over-surface and which admits for ultraviolet rays cast onto the other end opening through a light guide 56 to penetrate till the under-surface opening.
