Title: Method of controlling combustion of burner
Inventor: FUJIOKA SADAKAZU
IPC: F23N5/24
Filed: 1987-08-24
Abstract: PURPOSE:To prevent a seizure phenomenon of a fuel valve or a fuel pump from occurring by judging flame failure due to run-out of a fuel by the detected output waveform of a flame sensor and stopping the operation at an automatic reignition step, upon controlling the combustion of the burner. CONSTITUTION:In the case of using the burner 1 in a drier for drying grains, a combustion flame ejected through an ejection port 52 traverses and ventilates a drying chamber in the form of a hot air flow. Consequently, grains which are flowing down within the drying chamber are exposed to the hot air flow dried. During drying, the combustion flame ejected from the burner 1 is detected by a flame sensor 2. When a flame sensor 2 no more detects the combustion flame, it is judged to be flame failure and further judges whether it is due to fuel run-out or other factors from the detected output waveform of the flame sensor 2. When the flame failure is due to fuel run-out, the drier is automatically stopped. On the other hand, when the flame failure is judged due to a factor other than fuel run-out, the burner 1 enters into an automatic ignition step, and the burner 1 is reignited and drying of the grains is resumed.

Filed: 1989-08-18
Abstract: PURPOSE:To improve lubricating characteristics without destroying heat transfer characteristics of cooling structure by forming a fluorine thin film lubricating layer which is formed at each heat transfer surface or at a part of the heat transfer surface in a prescribed thickness. CONSTITUTION:A great amount of heat that is generated by a semiconductor element 2 is transferred by making contact from the base 9 of a heat transfer intermediate block 3 which is in contact with the rear of the element 2. A heat transfer block 6 has a V-shaped groove that is equal to a projection shape of the block 3. Having a flat plane, one side of the V-shaped groove comes into contact with the cylindrical upper face 10 of the block 3. Heat transferred to the block 3 is transmitted to the flat plane of the V-shaped groove from the cylindrical upper face 10 of the block 3. A fluorine thin film lubricating layer 13 is provided at the whole body of cooling structure or at the above block 3 by a thin film lubricating layer. The thin film of fluorine-type lubricating layer is thus either of a fluorine-contained compound having an ordinary greese like lubricating agent and a silanol group at the terminal or an organic film which contains a fluorine-containing compound at the surface. However, it is necessary for respective film thicknesses to be thinner than 5mum or less in order to minimize heat resistance to the utmost.
