37 results about "Minutes/day" patented technology

How many minutes in a day. A day is defined as a continuous period in which the earth completes a single rotation around the sun. It is a unit of time with an interval of approximately 24 hours. An hour can be defined as 1/24 of a day or reckoned scientifically as 3599 or 3601 seconds depending on conditions.

Time Certifying Server, Reference Time Distributing Server, Time Certifying Method, Reference Time Distributing Method, Time Certifying Program, and Communication Protocol Program

An object is to perform time certification at a low cost while ensuring high precision and high reliability. In a time stamp server according to the present embodiment, a time is measured by the unit of, for example, 100 milliseconds, and a time stamp is issued by using the time. However, what is important is generally a date in a time stamp although it depends on a certification target. Therefore, it is thought that no adverse affect occurs substantially, even if a second hand is doctored. Accordingly, in the present embodiment, the time measured by the internal clock of the time stamp server is divided into a part regarding the units equal to or larger than the unit of minute (year, month, day, minute) and a part regarding the unit of second (including the units smaller than one second, such as millisecond), and the part regarding the units equal to or larger than the unit of minute is audited by an auditory office, whereas the part regarding the unit of second is synchronized with a time distributed from a time distributing office. That is, as to the part regarding the units equal to or larger than the unit of minute, the coincidence with the reference time is confirmed, whereas the part regarding the unit of second is corrected by using the time distributed from the time distributing office.

Method for detecting picrasma quassioides alkali content in picrasma quassioides

The invention relates to the analytical chemistry field, particularly to a method for detecting picrasma quassioides alkali content in picrasma quassioides. The method comprises the following steps: preparing 1-carbomethoxy-Beta-carboline, nigakinone, and metiiylnigakinone standard solutions and drawing a standard curve; drying and smashing picrasma quassioides, and extracting to obtain a solution to be detected; detecting, wherein the detection chromatographic condition is that a C18 chromatographic column is adopted, the column temperature is 20-40 DEG C, the detection wave length is 205-280 nm, acetonitrile is taken as an A phase of a mobile phase while acid water is taken as a B phase of the mobile phase, the flow velocity is 1 mL/minute, and the elution procedures are performed in the way that the volume percent of acetonitrile is changed from 5% to 45% during the period from 0 minutes to 35 minutes, from 45% to 80 % during the period from 35 minutes to 40 minutes, from 80% to 90% during the period from 40 minutes to 50 minutes, and from 90% to 95% during the period from 50 minutes to 60 minutes; computing the content of three kinds of picrasma quassioides alkali as per the standard curve, wherein acids in acid water are phosphoric acid, formic acid or acetic acid, and the volume fraction of acid in acid water is 0.1-1%. The method can be used for the ration of three kinds of picrasma quassioides alkali at one time.

Hemoglobin storage method

The invention relates to a hemoglobin storage method which is characterized by comprising the following steps of adding a proper quantity of human blood into normal saline (a 0.9% NaCl solution) with the volume being 3-6 times that of the human blood, centrifuging at the temperature of 4 DEG C and the rotating speed of 2800r/min for 15-30 minutes to obtain a supernatant containing leukocytes, plasma proteins and platelets, extruding the supernatant, retaining deposited erythrocytes at the lower layer, repeating the washing process for more than 3-5 times until the supernatant is basically colorless, and removing other substances except for the erythrocytes to the maximum extent to obtain clean deposited erythrocytes; adding a certain quantity of deposited erythrocytes into equivoluminal sterilized high-purity deionized water to pre-expand for 5-15 minutes, finally, adding water with the volume being 2 times that of the deposited erythrocytes to carry out low permeation for 10-20 minutes, centrifuging at the rotating speed of 10000r/min for 30-60 minutes, and extracting the supernatant after centrifuging to obtain a hemoglobin solution; and subpackaging the purified hemoglobin solution into a 10ml sample bottle, sealing by using paraffin, and storing the purified hemoglobin solution in a brown bottle filled with a pyrogallic acid solution at the temperature of 4 DEG C, wherein the content of hemoglobin does not exceed 3% after the sample is stored for 4 months and is kept on the relatively-low level.

Detection and self-repair control method of temperature sensor error in dual-compressor air-conditioning system

The invention discloses a dislocation detecting and self-repairing control method for temperature detectors of a dual-compressor air conditioning system. The method comprises the steps that a, a control circuit is set up; b, a unit is started to operate for a minutes, one compressor (12) is started, the other compressor (12) is shut down, judgment is carried out, if one of the following two conditions is met, inserting dislocation of the temperature detectors is judged, according to the condition 1, detection is carried out once every b minutes, the exhaust temperature of the compressor (12) which is not started is increased by m DEG C or above, meanwhile, the exhaust temperature of the started compressor (12) is decreased by n DEG C or above, and according to the condition 2, the shutdown time of the compressors (12) exceeds c minutes, and the exhaust temperature of the compressors (12) is larger than or equal to z DEG C; and c, a master controller (1) turns on two normally open switches and turns off two normally closed switches. According to the method, whether inserting dislocation of the temperature detectors happens or not can be detected fast and accurately, and the dislocated temperature detectors can be automatically corrected to the correct compressors (12).
