Auxiliary lens mounting part

A shading hood member for a digital camera, which can easily be attached to a liquid crystal monitor of a digital camera of the existing type, and which has a simple structure and is compact in size, and which can be manufactured at low cost, is disclosed. The shading hood member is detachably attached to the liquid crystal monitor in such a manner as to cover the periphery of the liquid crystal screen of the liquid crystal monitor that is openably provided on the outside surface of a camera body.

In an ultrasonic probe for use in ultrasonic endoscope, ultrasonic diagnosing apparatus and other ultrasonic apparatuses, an ultrasonic vibrator is arranged in a recess formed in a cylindrical housing and is secured thereto such that portions of first and second electrodes are exposed out of the recess. First and second lead wires are embedded in the housing such that tips of the lead wires are exposed within connecting areas formed in the housing in communication with the recess. The tips of the first and second lead wires are connected to first and second electrodes of the ultrasonic vibrator with the aid of conductive members made of solder, conductive paste or conductive adhesive agent. The other end of the first and second lead wires are extended from the same end face of the cylindrical housing.

A method for dislodging cultured cells has the steps of preparing a culture container which has a growing surface on which cultured cells are grown, and which is filled with a culture solution in contact with the cultured cells, supporting the culture container on a pedestal to be reciprocally movable in a direction parallel to the growing surface, and reciprocally moving the culture container in the direction parallel to the growing surface and thus applying an inertial force on the cultured cells in the direction parallel to the growing surface, thereby dislodging the cultured cells from the growing surface. An apparatus for dislodging cultured cells has the pedestal for supporting the culture container and a reciprocating device for reciprocally moving the culture container supported on the pedestal in the direction parallel to the growing surface.

Biological substances such as tissues, cells, vaccines and viruses are cultured by the steps of: introducing a culture solution having the substances suspended therein into a closed culture vessel having a plurality of disc-like implantation plates arranged horizontally with a certain space between successive plates so that a predetermined number of the implantation plates is immersed in the culture solution; culturing the substances on the surface of the implantation plates; removing the substances from the implantation plates; suspending the removed cultured substances in a new culture solution; and successively repeating the steps of culturing, removing the cultured substances and suspending in a new culture solution while each time increasing the amount of newly supplied culture solution to progressively increase the number of implantation plates immersed in the culture solution. This process enables production of a large amount of biological substance from a small amount of seed substance by mass production in a simple operation without any contamination.

An image processing system converts gradation data of an image signal from a television camera into a digital code and transfers it to a computer. In the image processing system suitable means slice a portion which contains data of the image signal at a given level, means quantize a signal waveform obtained by the slice means, means count how many numbers of pulses obtained by the quantizing means at a given portion of one horizontal scan during each horizontal scan, and means for transfer counted values of the counting means to the computer at every completion of one horizontal scan.

Tissues or cells of a living body, especially a human body, are automatically and successively cultivated in a nutrient solution filled culture container disposed in a gas-sealed culture box by detecting, within the culture box, a multiplication condition of the tissues or cells and culture conditions which are represented by temperature, humidity and gaseous atmosphere in the culture box and pH value of the nutrient solution, controlling the culture conditions and apparatus for subculture of the tissues or cells within the culture box in accordance with the information detected.

Method for automatically and successively cultivating tissues or cells

An apparatus for automatically cultivating tissues or cells of a living body comprises a main body the inside of which is maintained in a predetermined atmosphere by an atmosphere control means. A container containing the tissues or cells and a nutrient solution is disposed in the main body and cultivated or multiplied tissues or cells in the container divided and fed for subculture into a plurality of empty cultivating containers disposed in the main body by an operating means which performs necessary operations for subculture. The atmosphere control means and the operating means are totally controlled by an apparatus control means.

An illuminating device for a microscope provided with a lighting control circuit controlled by changing the firing angle for which an impedance means is inserted between the output side of said lighting control circuit and primary side of the transformer in order to obtain a gentle rising curve for the current at the time of firing, thus to reduce the noise.
