Abstract: Provided is a thawing device for improving the thawing rate by agitation of the contents in a bag. The thawing device includes a first heater and a second heater to heat a bag containing a frozen matter, and a supporting unit to support the bag. The first heater is supported at guide grooves to move back and forth, and descends by approaching the bag, and a component force in the travelling direction of the self weight acts as a biasing force. The second heater is supported via a supporting shaft, and a pressing force acts on the upper and the lower side of the bag alternately. Excessive pressing force acting on the bag is alleviated and a damage of the bag can be reduced when the second heater presses the bag even in a frozen state.

Abstract: A method for producing contact materials being employed in electric/electronic circuits consists of a step 1-1 for supplying a spring base strip 1, a step 2-1 for supplying a noble metal wire 2, a seam welding step 3-1 for welding the metal wire 2 to the spring base strip after the spring base strip 1 and the noble metal wire 2 are held together, and a step 4-1 for winding a welded product. The method further includes a testing step 8-1 for determining a preciseness of a welded position and for determining a welded strength to peel the noble metal wire 2 from the spring base strip 1, which are performed between the seam welding step 3-1 and the winding step 4-1. Specimens for the testing step 8-1 are sampled at the beginning of and at the end of a production lot of the contact material.

Abstract: A diagnostic parameter calculation method, system and program which detect symptomatically abnormal electrocardiogram data of a patient, using R-R intervals detected from electrocardiogram data collected for a patient to generate a time-series data, then generating a series of partial sets B(j)'s, each B(j) consisting of successive elements starting from the j-th element of the time-series data, and calculating characteristic quantity set (yj, xj) for each B(j), wherein yj is the mean value of all elements, and xj is the mean value of each difference of the first element from each element in the B(j), then, after splitting the (y, x)-plane into lattices, parameters u, v, w are calculated as indices for diagnosis, wherein v is the number of lattices including only one characteristic quantity set, u is the difference subtracted v from the total number of the characteristic quantity sets, and w is the maximum number of characteristic quantity sets included in a lattice.

Abstract: The present invention provides a way to prognosticate some abnormality of the heart condition through analyzing the electrocardiogram of a patient. In R-R interval detection section 3, R-R intervals are detected from the electrocardiogram data collected in the electrocardiogram data collection section 1 to generate a time-series data. In the characteristic quantity calculation section 5, a series of partial sets B(j)'s is generated, where the partial set B(j) consists of n successive elements starting from the j-th element of the time-series data and n is a constant integer smaller than the total number of elements in the time-series data, and a set of the characteristic quantities (yj, xj) for each partial set B(j) is calculated, where yj is the mean value of all elements in the set B(j) and xj is the mean value of each difference of the first element from each element in the partial set B(j).

Abstract: The present invention provides a method for producing a contact member being employed in electric/electronic circuits. The method comprises a first process and a second process. The first process comprises a step 1-1 for supplying a spring base strip 1, a step 2-1 for supplying a noble metal wire 2, a seam welding step 3-1 for welding and combining the metal wire 2 with the spring base strip after the spring base strip 1 and the noble metal wire 2 held together; and a step 4-1 for winding a welded and combined product. The second process comprises a step 5-1 for punching the welded and combined product. The seam welding step 3-1 comprises a step 6-1 for setting welding conditions and a step 7-1 for circulating chilled water in a closed channel. A testing step 8-1 comprises a sub-step 8-1a for determining a preciseness of a welded portion and a sub-step 81b for determining a welded strength, is performed between the seam welding step 3-1 and the winding step 4-1.

Abstract: The present invention makes a diagnosis of a patient by detecting changes in the state of the patient appearing in an electrocardiogram from a variation in characteristic quantities repeatedly appearing in the electrocardiogram, for example, an R-R interval in an early stage and reliably. The ordinary distribution calculation section 3 receives the electrocardiogram data measured for a period INT1, calculates characteristic quantities repeatedly appearing in the electrocardiogram as time-series data and generates a set C of differences between neighboring elements of the time-series data. The ordinary distribution calculation section 3 further obtains m subsets by repeating m times the processing of randomly collecting n elements from this set C, and calculates an average value &mgr; and standard deviation &sgr; of the set of average values of these m subsets by assuming that the set of average values has normal distribution indicating the ordinary state of the variations in the characteristic quantities.
