The control box of the own work which I gained in the wooden box.

From the top, the indication part of the thermometer. The motor & gear box (250 r.p.m.) of TAMIYA company. The shaft connected with the screw.

Backward, watch for the photograph development.

The bottom of the control box.

Measure it with stirring water gently with the screw connected with the gear box. Center is the sensor of the thermometer. Both tips are located at about 5mm from the bottom of the pot. Temperature rise curve approaches in a straight line very much when it turns screw and water is stirred. Error is thought within 1-second.



The setup of a condition that a test is concrete.

  • A thermometer uses DijitalThermometerCT-160 of the CUSTOM company. This is the thing of the high performance indicated once with the type which inserts a stick-shaped sensor in the liquid 3cm and which I measure it with to less than a decimal point 1 digit in 1 second. Measuring range -40 degrees-110 degrees.
  • A pot uses 6 inches of the Hotton company. (It is large with the solo.).
  • Weight measuring uses 1475 electronic-type 1000g meter of the TANITA company. (0-100g : 1g unit, 100-500g:2g unit, 500-1000g:5g unit. Therefore, which measuring of the unit is abundant by 2g in.)
  • I don't measure humidity about 25 degrees-30 degrees by temperature in the inside, and don't measure atmospheric pressure by temperature, and the (about Tokyo Metropolis-height above sea level 20m) weather isn't fixed.
  • Wind breeze (the bottom of the ventilation fan).
  • A boiling point was made a moment 99.9 degrees, and maintenance was done before and after 99 degrees.

Test method (A liquid is different from the gas after NO.7.).

  1. Measure the weight of the fuel in advance. (cartridge gas cylinder body).
  2. Prepare for the water 1L of 10 degrees. (this, very very).
  3. Wipe out the dew which arrived at the surroundings of the pot.
  4. Put a pot on burner, and start time measuring at the same time with the ignition, and heat should be made the biggest.
  5. Measure time in every 10 degrees. (20 degrees 30 degrees 40 degrees---).
  6. Measure a moment 99.9 degrees as a seething moment.
  • In the case of the gas burner.
  1. Extinguish the fire at once, and put a pot in the low heat of the life stove, and maintain seething.
  2. Measure the weight of the cartridge simple substance, and calculate the amount of gas that seething took it.
  3. Set burner again, and put a pot, and ignite.
  4. Remove a pot, and throw hot water away. Start time measuring at the same time, and make it the minimum heat that I maintain seething.
  5. Extinguish the fire after 10 minutes, and measure the weight of the cartridge simple substance, and calculate the amount of gas that maintenance takes it for 10 minutes with seething.
  • In the case of the liquid fuel burner (Do A and B two times.).
  • A
  1. Extinguish the fire at once, and measure the weight of the gas cylinder or the body, and calculate the weight of the fuel which seething took.
  • B
  1. Weaken heat, and make it the minimum heat that I maintain seething without extinguishing the fire after seething as well. the (flame which became stable).
  2. If the heat which became stable is set, I remove a pot, and you may throw hot water away.
  3. Extinguish the fire in 10 minutes from the seething moment, and measure the weight of the gas cylinder or the body, and calculate the fuel weight that maintenance takes it for 10 minutes with seething.

Method Commentary.

  • I measured it twice though it was troublesome because gasoline didn't become stable and there was fuel omission in the separation type though I ignited again when I extinguished the fire and space was vacant. It went from the condition that it got cold twice.
  • The fuel which maintenance takes for 10 minutes is 4g`8g mostly, and reliability is low, and originally I want to measure it for about 100 minutes 2g with measuring of the unit. First of all I compromise because it is actually difficult.
  • Temperature, humidity are thought that there are probably few influences because temperature rises rapidly about burner that it becomes heated before and after five minutes. When I use a gas cartridge in the mountain, it is thought the thing that heat declines remarkably in less than 0 degree.
  • I don't examine a change in heat due to the decrease of the fuel.
  • I don't examine vaporization cooling of the fuel, a change in heat by the degree of heating.
  • It decides to originate in the "good point of the convenience", and I don't correct time loss by the ignition, putting out the fire specially.
  • Gasoline unity-type things are not accurate data because it becomes a unit 5g with weight measuring.
