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.

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.

PROBLEM TO BE SOLVED: To solve the problem of an acoustic droplet ejector that the temperature of liquid being ejected can not be controlled sufficiently. SOLUTION: The droplet ejector 200 for ejecting second liquid acoustically as a droplet is provided with a first fluid chamber 220 being fed with first fluid (e.g. cooling liquid) continuously as a high velocity laminar flow in addition to a second fluid chamber 230 storing second liquid being ejected as a droplet.

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.

PROBLEM TO BE SOLVED: To make ink drops supplied from a plurality of supplying sources uniform. SOLUTION: This system includes a cooling system 260 for compensating non-uniform heating effect in a print head causing the variation of a temperature. By setting a distribution and an efficiency of the cooling system, the temperature of ink is maintained in a constant level through the print head.
Abstract:
PROBLEM TO BE SOLVED: To correct the non-evenness of the size of individual liquid droplets and the ejection velocity of an acoustic ink jet printing head. SOLUTION: Control signals CS1-CS32 control appropriate switches Z1 respectively and also control time for an RF signal to be applied to each of transducers 52 and lasting time of the application. In this case, the pulse width of the control signal CS1-CS32 can be changed based on the correction data of a reference table 66. The ascending edge of the control signals CS1-CS32 is retarded but the descending edge is not changed, based on correction data and thus the pulse width of the control signals CS1-CS32 is modulated. The liquid droplet size or the ejection velocity is controlled using the modulation of the pulse width.
