Abstract: Methods for testing proper operation of drop ejection units in a multi-ejector system are provided to determine whether the drop ejectors have been properly filled and/or the ejectors are emitting fully formed droplets. The method include testing the ejectors prior to drop ejection. In this method, a priming system is ejected onto a test substrate to allow a scanner to determine the existence of the fluids at selected locations.

Abstract: A method for manufacturing precise complex three dimensional structures in which minute drops of both a product layer and a sacrificial layer are emitted from an acoustic device. The process is a two step process wherein first the three dimensional structure is built in layers which are composed of either a sacrificial layer or a product layer or some configuration of both. Once the structure has been completely built up, then the sacrificial layer is removed leaving only the complex three dimensional structure.

Abstract: PROBLEM TO BE SOLVED: To accurately work a bioliquid particle discharging apparatus from the start of a discharge process as bioliquid is expensive and the liquid particle must be formed at a very exact position. SOLUTION: A priming device 250 is disposed above a nozzle 204 having a structure discharging bioliquid from a discharge liquid reservoir 192. The priming device 250 is equipped with a vacuum nozzle 252 connected to a vacuum unit 254. A tube or sleeve 256 is disposed around the vacuum nozzle 252. The vacuum nozzle 252 is set above the discharge nozzle 204, and then the vacuum nozzle 252 moves downward, which causes slight contact of the tube 256 with the nozzle 204. The discharge liquid reservoir 192 is vacuum-deaerated by the vacuum action.

Abstract: PROBLEM TO BE SOLVED: To provide a method for accurately inspecting whether a biofluid discharge ejector included in a multiple ejector system normally operates or not. SOLUTION: The method for inspecting whether the droplet discharge unit included in the multiple ejector system is in normal operation or not comprises scanning a test substrate having discharged the fluid and detecting whether a vacuum unit corresponding to the specific droplet discharge unit has released the fluid or not.

Abstract: PROBLEM TO BE SOLVED: To provide an improved organic liquid particle discharging device. SOLUTION: A organic liquid particle discharging mechanism comprises a transducer which generates an energy used to discharge organic liquid particles, and a chemical cartridge which is a organic liquid holder holding an organic liquid. The chemical cartridge has such structure as to hold a small volume of the organic liquid, with the organic liquid avoided from contaminated. The chemical cartridge is connected to the liquid particle discharging mechanism when actuated so that the organic liquid particles are discharged when the liquid particle discharging mechanism is actuated. The liquid particle discharging mechanism is very efficient, capable of configured as a two-piece type device or as a one-piece type disporsable device.

Abstract: PROBLEM TO BE SOLVED: To provide a method and mechanism to ensure the quality control of printed biological assays. SOLUTION: Various bio-fluids put fully in a multiple ejector system comprising a plurality of individual fluid drop ejectors are printed on a base board 172 as fluid drops 174. Each bio-fluid includes at least a carrier fluid, a bio- substance used in the test, and a marker such as fluorescent dyes. When the biological assays 170 formed from bio-fluid drops are printed, it is scanned by a scanner 176 capable of sensing the marker, and a signature output signal for respective fluid drop is determined. This signature output represents a signal from respective fluorescent marker included in the bio-fluid. Then the signature output determined by the scanning is compared with a predicted signal output for the bio-fluid put fully in the corresponding fluid drop ejector, and thus quality control is conducted.

Abstract: PROBLEM TO BE SOLVED: To provide an organism liquid level-controlling mechanism that is used for an organism liquid drip discharging device having a satisfactory shape while no organism liquid drips to be discharged are contaminated. SOLUTION: The organism liquid drip discharging device has an acoustic type liquid drip-discharging mechanism 14 where a transducer is provided, and retains organism liquid 38 where an organism liquid cartridge 12 is provided separately from the mechanism 14. When the acoustic liquid drip-discharging mechanism 14 is operated, energy that is generated by the transducer is gathered while focusing on the liquid surface of the organism liquid cartridge 12 by a Fresnel lens 22 via acoustic coupling liquid, and the organism liquid 38 is discharged in a liquid drip shape. When the height of the organism liquid 38 in the organism liquid cartridge 12 becomes a certain level or less, additional acoustic coupling fluid is supplied by a plunger 96, and the height of the entire organism liquid cartridge 12 is increased, thus adjusting the height in the organism liquid level.

Abstract: PROBLEM TO BE SOLVED: To resolve a problem that a conventional bio-fluid discharging ejector causes much biological pollution and its function for correctly dripping bio- droplets is low, and the volume of each bio-droplet is large so that a large number of bio-droplets are needed. SOLUTION: The problem can be resolved by providing a plate having plural sets of pins extending outward from its surface, a printed wiring board having at least one power connection pin extending from its surface, and plural droplet discharging units 10 each including positioning slots 48 and 50 and a transducer 16, and mounted by fitting the positioning slots 48 and 50 to at least one of the sets of pins, for a multi-ejector system for discharging an array of a bio-fluid as the droplets.
