摘要： A method for manufacturing a liquid discharge head comprises the steps of providing a head main body having liquid flow paths, and an aperture surface having flow path openings communicated with the flow paths; providing a discharge port plate having extrusions each on the circumference of an inside opening communicated with each of the discharge ports, being on the inner face on the side opposite to the discharge port surface provided with discharge ports for discharging liquid, and a base having a substantially flat surface. For this method, the discharge port plate is arranged in a state of these surfaces formed integrally to be in contact; bonding the aperture surface and the inner face to fit the extrusions into the flow path openings by pressing the head main body and the base in the direction of the head main body and the base approaching each other with the discharge port plate between them; and separating the base from other members. With the method of manufacture thus structure, the liquid discharge head presents an excellent discharge efficiency by the provision of the extrusions that enter the flow paths from the orifice plate. It also becomes possible to manufacture a highly reliable liquid discharge head by a simpler manufacturing apparatus in a shorter period of time at lower costs.

摘要： It is an object of the present invention to ensure a desired precision in positioning an orifice plate with respect to liquid flow paths of a head main body, so as to prevent a failure liquid discharge which will possibly be caused due to a problem involved in a process of forming the orifice holes. In detail, a head main body is formed on the lower wall thereof a plurality of heating elements, has a plurality of liquid flow paths formed by dividing an internal space with a plurality of liquid flow path walls and arranged in parallel relationship with one another. On either side of the plurality of the liquid flow paths there are formed two dummy liquid flow paths. An orifice plate is formed with a plurality of orifice holes arranged in parallel with one another for discharging ink. Further, on either side of the plurality of the orifice holes there are formed two projected portions so shaped that they are capable of engaging with the opening ends of the dummy liquid flow paths. Each of the projected portions is formed with a dummy orifice hole which is not used for discharging ink during recording operation. A desired positioning can be effected by engaging the projected portions of the orifice plate with the dummy liquid flow paths.

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： A liquid discharge head includes plural heat generating members, each linearly communicating with a discharge port, a liquid flow path communicating with each discharge port and having a bubble generating area in which a movable member is provided, a limiting portion opposed to the bubble generating area in the liquid flow path for limiting displacement of the movable member, and a circuit for receiving data of a predetermined number of bits for each heat generating member and generating drive pulses for each heat generating member based on the respective input data. Substantial contact between the displaced movable member and the limiting portion renders a portion of the liquid flow path including the bubble generating area a substantially closed space except for the discharge port. The number of drive pulses generated from the input data is larger than the predetermined number of bits for at least one set of the data.

摘要： A method for the discharge of a liquid and a liquid discharge head are provided which produce stable discharge of the liquid and, at the same time, facilitate the supply of the liquid by repressing the oscillation of a movable separation membrane during the extinction of bubbles. The method comprises using a movable separation membrane for separating a first flow path communicating with a discharge port for discharging the liquid and a second flow path furnished with a bubble generating region for generating bubbles in the liquid by the use of a heating element, disposing a movable member opposed to the bubble generating region across the movable separation membrane and furnished with a free terminal in the direction of liquid discharge, causing separation between the movable separation membrane and the movable member during the contraction of the bubbles, and inducing the intrusion of the liquid therebetween.

摘要： A liquid discharge method is designed for a liquid jet head provided with first discharge openings, a first liquid flow path conductively connected with each of the first discharge openings, first energy generating devices for generating energy for the discharge of droplets from the first discharge openings, second discharge openings, a second liquid flow path conductively connected with each of the second discharge openings, and second energy generating devices for generating energy for the discharge of droplets from the second discharge openings. Then, preceding the discharge of the first droplet from the discharge opening at a first discharge speed v.sub.1, the second droplet is discharged from the second discharge opening at a second discharge speed v.sub.2 smaller than the first discharge speed, and before each of the liquid droplets being impacted on an object, the first liquid droplet and the second liquid droplet are allowed to collide with each other to be combined. In this way, it becomes possible to allow two droplets to be in contact or to collide with each other reliably to be mixed between the liquid jet head and the object within a range that does not render any hinderance practically even if discharge speeds may fluctuate, hence obtaining precise images in higher quality.
