摘要： An ink supply port is opened in an Si substrate on which an ink discharge energy generating element is formed, by anisotropic etching, from a back surface opposite to a surface on which the ink discharge energy generating element is formed. When the anisotropic etching is effected, OSF (oxidation induced laminate defect) is remained on the back surface of the Si substrate with OSF density equal to or greater than 2×104 parts/cm2 and a length of OSF equal to or greater than 2 μm.

摘要： A substrate for a recording head includes a circuit through which current flows upon impression of a source voltage, irrespective of the operating state of an energy converting element, and a current cutoff means for cutting off current to the circuit in response to an entered control signal. A reset signal for achieving a standby state of the printing operation serves as the control signal. The current cutoff circuit is operated when the reset signal is active in an H state, and it cuts off the constant current. By cutting off the constant current, the leak current of a heater power source VH may be accurately measured, permitting determination of whether the source voltage wiring is properly insulated from other circuit elements of the substrate. The constant current may also be cut off in the standby state, in which printing is not performed, so as to reduce power consumption.

摘要： In a liquid discharge head having a movable member displaced by generation of a bubble, endurance of stepped portions of the movable member and of root portions of movable parts of the movable member is enhanced and flexure deformation of the movable member is prevented to enhance endurance of the member. A pressing member for covering stepped portions of a movable member and root portions of branched movable parts is provided within a flow path. A part of the pressing member is tapered and extends to a downstream side (toward a discharge port) to be spaced apart from the movable member, thereby forming a flexure regulating portion opposed to and spaced apart from an intermediate portion of the movable member. The pressing member and the flexure regulating portion suppress excessive deformation of the movable member.

摘要： An ink jet head circuit board is provided which has heaters to generate thermal energy for ink ejection as they are energized. This circuit board has the heaters formed with high precision to reduce their areas. It also has provisions to protect the electrode wires against corrosion and prevent a progress of corrosion. The substrate is deposited with the thin first electrodes made of a corrosion resistant metal. This is further deposited with the resistor layer. The second electrodes made of aluminum are deposited to overlap the first electrodes to form the heater without causing large dimensional variations among the heaters. With this construction, if a defect should occur in a protective layer on or near the heater, a progress of corrosion can effectively be prevented because the material of the resistor layer is more resistant to encroachment than aluminum and the first electrodes are corrosion resistant.
