摘要:
A method of enhancing the accuracy and reliability of a chemical analysis, wherein a reaction is carried out by combining a sample liquid with at least one reagent to form a test liquid and the test liquid is photometrically scrutinized a plurality of times over an extended period of time to derive a number of photometric values. The derived values are then stored and a plurality of the stored photometric values are preliminarily selected from a given time frame, wherein the plurality of preliminarily selected values are less than a total number of stored photometric values. Successive preliminarily selected photometric values are compared with at least one predetermined standard to derive a comparison result and upon indication that useful data cannot be calculated from the preliminarily selected photometric values, a secondarily selecting step of selecting at least one photometric value from all of the stored photometric values, which were not preliminarily selected, is used to derive an analytical result which represents a concentration of a chemical substance in the test liquid or an activity of the test liquid.

An automatic focussing apparatus for microscopes includes a pair of photoelectric transducer elements disposed short of and beyond the imaging position, respectively, of an optical system which is used for the purpose of focussing. Each element is connected with a separate loop comprising an A/D converter which converts an output signal from the associated element corresponding to each picture element into a digital quantity, a sample-and-hold circuit, a calculation circuit which responds to the digital signal to derive an evaluation function, and an accumulator which stores the resulting value. The individual accumulators are connected with a comparison circuit, which is in turn connected with a focus control circuit controlling the optical system.

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.
摘要:
A method of writing data in a track on a optical card by projecting a writing laser beam whose output power is modulated in accordance with the data to be recorded, wherein immediately after writing the data with the aid of the writing laser beam having a nominal value A.sub.3, the data is read out of the optical card and confirmed whether the data has been correctly written or not. If the data is not correctly written on the optical card, the same data is written again in another track on the optical card with the aid of the writing laser beam whose output power is changed to a higher level A.sub.4. Immediately after this second writing, the data is read out of the optical card to check whether the data has been correctly recorded or not. The data writing operation is repeated by a predetermined number of times by changing the level of the output power of the writing laser beam successively in the order of A.sub.3, A.sub.4, A.sub.2, A.sub.5, A.sub.1, wherein A.sub.1

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.
摘要:
An image acquisition system includes a camera as an image acquisition device and a commanding device configured as a member separate from the camera to transmit a command for controlling the camera to the camera so that the camera can perform the operation corresponding to the command. The ability to transmit/receive the command between the commanding device and the image acquisition device is switchable.
摘要:
An image acquisition system includes an image acquisition device and a commanding device configured as a member separate from the image acquisition device to transmit a command to the image acquisition device for controlling the image acquisition device in such a manner as to permit the image acquisition device to operate in response to the command. The image acquisition device transmits to the commanding device identification information permitting the image acquisition device to identify the commanding device. The commanding device receives the transmitted identification information and transmits a command with authentication information contains authentication information permitting the image acquisition device to authenticate the commanding device, the authentication information containing one of the received identification information and information derived from the identification information.
摘要:
An optical record medium in the form of a wallet-size optical card including a data region in which a number of data tracks are provided in parallel with each other, an identification region provided on one side of the data region, and a mark region provided on a side of the identification regions. Data signals are recorded in the data tracks and addresses of the data tracks are recorded in the identification region. Every time a data signal has been recorded in a data track, a mark is recorded in the mark region at such a position that the mark is aligned with the relevant data track viewed in a track direction.
