Abstract: A lid body 200 is divided, on its front side, into three parts, that is, a pair of first movable parts 220 in the form of curved plates on both sides of the body and a second movable part 230 in the form of a flat plate in the middle of the body. A container body 100 is provided with a front engagement member 131 which is displaceable in front and in the rear of the body 100. The first movable parts 220 have front engagement members 221 formed at their front ends to be engageable with the front engagement member 131. While, the second movable part 230 has a disengagement member 231 formed at the front ends. The first movable parts 220 on elastic deformation are engaged with the front engagement member 131. When the second movable part 230 is subjected to depression of its upper face at the front end so that the disengagement member 231 causes the front engagement member 131 to be displaced forward, the engagement of the front engagement member 131 with the front engagement members 221 is released.

Abstract: The cover glass adhering device is capable of dropping fixed amount of mounting medium, using cover glasses having various length, and being small in size. In the cover glass adhering device, a drop nozzle drops the mounting medium onto a specimen on a slide glass, which is held horizontally. A removing member removes a drop of the mounting medium dangling from the drop nozzle. The removing member is located outside of the slide glass. A traveling unit travels the drop nozzle, from which the dangling drop of the mounting medium has been removed by the removing member, along the specimen on the slide glass so as to drop a prescribed amount of the mounting medium over the specimen.

Abstract: The method of the present invention is capable of securely removing air from a space between the cover glass and a slide glass and securely locating a damaged part of a specimen outside of a visual field of a microscope. One end of the cover glass is held by a sucking pad, which is provided to an arm capable of rotating and vertically moving. Then, cover glass is obliquely held in a state. The one end of the cover glass is located on the upper side with respect to the other end thereof. A position of a rotational axis of the arm is moved to a position under the slide glass, and the arm is rotaed to make the other end of the cover glass contact the slide glass and curve the cover glass, and the one end of the cover glass is gradually moved toward the slide glass.

One end of the cover glass is held by a sucking pad, which is provided to an arm capable of rotating and vertically moving. The cover glass is obliquely held with respect to the slide glass. The one end of the cover glass is held higher than the other end of the cover glass. A position of a rotational axis of the arm is moved to a position under the slide glass. The arm is rotated to make the other end of the cover glass contact the slide glass and curve the cover glass. The one end of the cover glass is gradually moved toward the slide glass.

Abstract: A liquid-processing apparatus for processing vital specimens, such as an automatic staining apparatus for staining specimens of vital tissues or the like for microscopic examination, has a cabinet (7) internally provided with a lower plate (8) and an upper plate (9). Rinsing vessels (10) and chemical solution vessels (11) are placed on the lower panel (8), and chemical solution vessels (11) are placed on the upper plate (9). A hanger arm (24) supporting a staining basket (13) containing glass slides carrying specimens affixed thereto moves longitudinally in a lower space (26) extending over the lower plate (8) or an upper space (28) extending over the upper plate (9). The staining basket (13) can be moved between the spaces (26, 28) through a passage (29) formed in the upper plate (9). The liquid-processing apparatus requires a small floor space for installation and can be installed in a small place.

Abstract: Apparatus for dyeing tissues sampled from a living body for the purpose of observing immunoreaction of the tissues has a dyeing tray with a plurality of plateaus arranged in parallel disposition. A slide is so placed over each plateau that a wedge-shaped gap of capillary dimension is formed between the plateau and the undersurface of the slide to which a sampled tissue is attached. A liquid drip surface and a liquid discharge port are formed at one end of the top surface of each plateau. A liquid delivery port is formed on a side wall of the tray so as to communicate with the liquid discharge port. The liquid delivery port and the drip surface are always exposed. A dyeing liquid or a rinsing liquid is dripped onto the exposed drip surface and spreads into the gap for dyeing the tissue or rinse the relevant parts. After the dyeing or rinsing, the used liquid is sucked and discharged by way of the liquid delivery port.

Abstract: A device for dyeing tissues of living bodies for immune response observation comprises dyeing block on which are formed a plurality of adjoining base portion each having a flat upper surface. On one side of the base portion is formed a ridge, and on the other side of the base portion is formed a supporting surface which is slightly higher than the ridge. A slide glass having a tissue attached to one surface is placed above each of the base portion with the surface thereof facing the upper surface of the base portion, so as to bridge the ridge and the supporting surface in such a manner that a thin wedge-shaped gap is defined between the upper surface of the base and the undersurface of the slide glass. Dyeing liquid is dripped from above onto the upper surface of the base portion which is not covered by the slide glass. The dripped dyeing liquid spreads into the wedge-shaped gap by capillary action, whereby the tissue on the undersurface of the slide glass is dipped in the liquid and dyed.

Abstract: An apparatus for dyeing the skeletons of animal fetuses with medical liquids includes a treating tank for accommodating a cage in which the fetuses are put, in which tank the medical liquids are circulated by a medical liquid pump. When fed into the treating tank, the circulating medical liquids are dispersed over the liquid surface. The skeleton-dyeing apparatus further includes a neutralization tank for neutralizing used-up medical liquids discharged from the treating tank.
