Abstract
Abstract A thermal analysis device with a sample transporting machine which automatically carries out pretreatment of a sample to quickly heat or cool it. The configuration includes an electric furnace, a temperature controller, a temperature program setter, a sample placing/removing program setter, and a sample transporter, wherein the said sample placing/removing program setter commands the said sample transporter to place the said sample in or remove it from the said electric furnace in synchronization with a synchronization signal from the said temperature program setter and in accordance with a preset sample placing/removing program and, hence, the said sample placing and removing operations (i.e. to place a sample in the electric furnace or, conversely to remove a sample from the electric furnace) are carried out in the electric furnace which is performing a heating operation or a cooling operation in accordance with a temperature program output by the said temperature program setter.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
199 words
In a thermal measuring and testing system adapted to provide temperature data for analysis on a sample to be tested, the improvement wherein said thermal measuring and testing system comprises: an electric furnace in which a sample is placed; a temperature controller which controls the temperature of said electric furnace; a temperature program setter which outputs temperature control information to said temperature controller, for setting serial steps which have start temperatures, finishing temperatures, heating or cooling rates and holding periods at finishing temperatures, and outputting synchronization signals at each step; a sample placing/removing program setter connected for receiving said synchronization signals of each of said serial steps from said temperature program setter for outputting, in response to each synchronization signal, a selected one of a preset sample maintaining command for maintaining the sample in its existing position, a sample placing command for placing the sample in said electric furnace and a sample removing command for removing the sample from said electric furnace; and a sample transporter which holds the sample and places the sample in or removes the sample from said electric furnace according to a sample placing command or a sample removing command from said placing/removing program setter.
Claim 2
Dependent Claim
199 words
In a thermal measuring and testing system adapted to provide temperature data for analysis on a sample to be tested, the improvement wherein said thermal measuring and testing system comprises: an electric furnace in which a sample is placed; a temperature controller which controls the temperature of said electric furnace; a temperature program setter which outputs temperature control information to said temperature controller, for setting serial steps which have start temperatures, finishing temperatures, heating or cooling rates and holding periods at finishing temperatures, and outputting synchronization signals at each step; a sample placing/removing program setter connected for receiving said synchronization signals of each of said serial steps from said temperature program setter for outputting, in response to each synchronization signal, a selected one of a preset sample maintaining command for maintaining the sample in its existing position, a sample placing command for placing the sample in said electric furnace and a sample removing command for removing the sample from said electric furnace; and a sample transporter which holds the sample and places the sample in or removes the sample from said electric furnace according to a sample placing command or a sample removing command from said placing/removing program setter.
Claim 3
Dependent Claim
50 words
A thermal measuring and testing system as defined in claim 1 wherein said temperature program setter outputs a given synchronization signal when said electric furnace has been heated to a start temperature, and said sample placing/removing program setter outputs a sample placing command in response to the given synchronization signal.
Claim 4
Dependent Claim
43 words
A thermal measuring and testing system as defined in claim 2 wherein said sample placing/removing program setter is programmed to output selected ones of the commands in a selected order and outputs each command in turn in response to a respective synchronization signal.
Claim 5
Dependent Claim
43 words
A thermal measuring and test system as defined in claim 1 wherein said sample placing/removing program setter is programmed to output selected ones of the commands in a selected order and outputs each command in turn in response to a respective synchronization signal.
