Abstract:
A printer head which discharges only an ink or mixes an ink with a dilution liquid to discharge the mixed liquid is formed at a portion thereof at least around a nozzle opening on a nozzle opening side surface by a polyimide based polymer to enable forming a recorded image of high resolution and make productivity favorable. The polyimide based polymer is preferably polyimide siloxane which has a water absorption coefficient of 0.4 % or less when immersed in water of 23 °C for 24 hours and is formed through polymerization with heating of 180 °C or less. Further, the portion of the nozzle forming section of the printer head which is not constituted by the polyimide based polymer, is preferably constituted by polysulfone, polyethersulfone and a polyimide based polymer which has water absorption coefficient of 1.0 % or more when immersed in water of 23 °C for 24 hours. Also, a nozzle is preferably formed by ablation processing which uses excimer laser.
Abstract:
In a printer device of the invention, a diaphragm having a thermoplastic layer and a pattern layer rests on a main surface, on which a liquid supply passage of a pressure chamber defining portion is formed, and when the thermoplastic layer of the diaphragm is heated to be bonded to the pressure chamber defining portion under pressure, pressure is concentratedly applied on the pattern layer of the diaphragm, an unnecessary pressure is not applied to that portion opposite to the liquid supply passage, on which the pattern layer is not formed, the liquid supply passage is not clogged by the thermoplastic layer, and an operation of bonding the diaphragm to the pressure chamber defining portion, in which a pressure chamber is defined, is easily performed. Further, in the printer device of the invention, an adhesive layer composed of a thermoplastic resin is formed between the pressure chamber defining portion and the diaphragm to adequately ensure an adhesive strength of the diaphragm relative to the pressure chamber defining portion. Also, in the printer device, if respective nozzles are formed in a nozzle forming member and an adhesive layer composed of a thermosetting resin is formed between the pressure chamber defining portion and the nozzle forming member, the printer device is manufactured such that after adhesion is effected between the diaphragm and the pressure chamber defining portion, the pressure chamber defining portion and the nozzle forming member are bonded to each other at room temperature, by which the adhesive layer composed of a thermoplastic resin is not influenced and which does not apply heat or the like on a liquid repellent film even if it is formed on the nozzle forming member, so that selection of a liquid repellent film is enlarged in range.
Abstract:
In a printer, since a hard member is disposed between a discharge nozzle and a pressure chamber corresponding thereto which has a nozzle introduction hole establishing a communication between the nozzle and the chamber, or a hard member is disposed between a discharge nozzle and a first pressure chamber corresponding thereto, and a constant flow rate nozzle and a second pressure chamber corresponding thereto, the hard members having, respectively, a first nozzle introduction hole establishing a communication between the discharge nozzle and the first pressure chamber and a second nozzle introduction hole establishing a communication between the constant flow rate nozzle and the second pressure chamber, when a pressure is applied to the pressure chamber, the first or second pressure chambers by a pressurising means, the pressures in those pressure chambers increase effectively and stably, and since the discharge nozzle and the constant flow rate nozzle are formed from a resin member, it is possible to form a discharge nozzle and a constant flow rate nozzle in such a manner as to sufficiently satisfy the working properties relative to laser and with good accuracy, whereby reliability and productivity can be improved.

PROBLEM TO BE SOLVED: To provide a biological sample image acquiring apparatus which can improve the detection precision. SOLUTION: A focal plane FP of an objective lens 12A is moved in a thickness direction of a biological sample SPL, and at the same time, an image formed on an imaging device 30 is moved in an in-plane direction. During the movement, the imaging device 30 is exposed to light to acquire a biological sample image. Thereby, the image based on the movement can be distinguished from the noise, the detection precision can be improved. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide: a biological sample image-acquiring apparatus capable of efficiently acquiring the image of a sample region; a biological sample image-acquiring method; and a program. SOLUTION: The blur of the sample region is avoided even when the start period of exposure for an imaging device is prior to the stop time point of a sample stage by making a stage follow to the sample stage. Further, the start period of the exposure for the imaging device is prior to the stop time point of the sample stage, so that the time from a stage start time point to an imaging completion time point is shortened for one sample region.

SOLUTION: A biometric apparatus 1 consists of a light source 10, a glass substrate 11, an image capture lens 12, an image pickup device 13, an image processing section 14, a pattern retention section 15, an authentication section 16, a light source drive section 17, an image pickup device drive section 18, and a control section 19. The light source 10 illuminates a light by selectively changing over between a light L1 in a high-transmission wavelength band relative to a living body and a light L2 in a low-transmission wavelength band relative to the living body. The image pickup device 13 generates captured image data in both cases where illuminating the lights L1 and L2, and the image processing section 14 generates difference image data of the captured data. Images formed by receiving a reflected light L2a formed by the illumination of the lights L1 and L2 and a light L3 such as a stray light, outside light and the like are substantially same so as to exclude the signal components of the reflected light L2a and the outside light L3.
