Title: Ink jet printing head
Inventor: HAGIWARA YOSHIHIRO
IPC: B41J2/135
Filed: 1993-12-09
Abstract: PURPOSE:To shorten an ink refilling time and to suppress the vibration of a meniscus after refilling by gradually increasing the cross section crossing the flow direction of ink of a nozzle part at a right angle toward a nozzle emitting side through the min. inner diameter part. CONSTITUTION:A nozzle part 2 is formed so that the cross section crossing the direction of the flow 4 of ink at a right angle becomes small from the ink supply side 6 of an orifice plate 1 toward the ink emitting emitting side 7 to reach the min. inner diameter part 2A and subsequently becomes wide gradually. When ink 3 is expanded by the heat generated from a heater 20 to which a current is supplied through an electrode, the ink is emitted from the ink supply side 6 of the orifice plate 1 toward the ink emitting side 7. After emission, the nozzle part 2 is refilled with the ink 3 supplied from the ink passage 30 by the capillary phenomenon of the nozzle part 2 to return to the state before emission. The flow velocity of the ink 3 at the time of the arrival at the leading end of the nozzle part 2 can be lowered and the refilled ink 3 becomes hard to generate vibration.

Abstract: PURPOSE:To improve machining accuracy by obtaining a difference between a target machining dimension and a machining dimension after assembly of parts into an engine body, adjusting the height of the reference plane of a supporting base and clamping pressure by a clamping means according to the difference. CONSTITUTION:In machining a part to be assembled into an engine, for example, a cam shaft housing (work) 26, the heights of the reference pads 52-54 of a supporting base 51 are set at prescribe heights, and a pressure for the work 26 to be clamped by clamp shafts 58-61 is set at a prescribed pressure, and the work 26 is held. In such a condition, mounting holes 31, 32 are ground, the work 26 after machining is assembled into a cylinder head 16, and its coaxial degree is measured. According to the magnitude of dislocation of the coaxial degree, the heights of the reference parts and the clamping pressure by the clamp shaft are adjusted by a control part 68. It is thus possible to machine the work 26 in such a condition that is almost identical to that when it is assembled into the cylinder head 16.

Abstract: PURPOSE:To prevent the damage to a gate insulating film by removing a resist film by dry etching, in the condition that a not patterned first insulating film is covered with a conductive layer. CONSTITUTION:The surface of an Si wafer 1 is coated with an oxide film 2, and thereon a polysilicon layer 3 is made. Then, by CVD method, the obverse and the reverse of the polysilicon layer 3 overlaid on the Si wafer 1 are covered with a nitride film 7. And a resist film 4 is made in the specified region on the nitride film 7 above the surface of the Si wafer 1. Next, with the resist film 4 as a mask, the nitride film 7 is dryetched, thus only the nitride films 7 on the gate electrode formation area at the surface of the Si wafer 1 and on the reverse of the Si wafer 1 are left. Then, by oxygen plasma, the resist film 4 is all removed from the surface. At this time, since the surface of the oxide film 2 being a conductive material is covered with a polysilicon film 3, the plasma damage to the oxide film 2 by oxygen plasma is prevented.
