Abstract: A forced flue type combustion device in which an orifice is provided in at least one of an air supply passage and an exhaust passage, and in which the existence/nonexistence of a clog is determined on the basis of a detected pressure difference between the pressures on the upstream and downstream sides of the orifice, is arranged so that the existence/nonexistence of a clog can be determined with accuracy even during weak combustion with a low rotational speed of the combustion fan. Processing for increasing the rotational speed of the combustion fan is intermittently executed during weak combustion. During weak combustion, clogging determination processing based on the detected pressure difference value is executed only when the rotational speed of the combustion fan is increased. Clogging determination processing is started after the rotational speed of the combustion fan has become stable.

In the presence of an enzyme, an L-?-amino acid of formula (I): (in the formula (I), R1 is a hydrocarbon group) is reacted with an aldehyde of formula (II): (in the formula (II), R2 is a hydrocarbon) to produce an L-serine derivative of formula (III). .

Abstract: A method for producing ?-hydroxy amino acid and its optically-active isomer is provided. The ?-hydroxy amino acid is produced by reacting a predetermined D-?-amino acid and 5,10-methylene tetrahydrofolic acid in the presence of an enzyme derived from a microorganism belonging to the genera Paracoccus, Aminobacter, or Ensifer.

Abstract: There is provided a remote control unit capable of setting time by a simple operation at a time when a battery is attached. In the remote control unit which is operated by the battery to remote-control operation start and stop of an apparatus main body and in which setting of a timer operation by a clocking means is possible, when the battery is attached to start the operation, a forced mode setting means displays a clocking initial value in a liquid crystal display in step 1, starts a monitor timer in step 2, and sets a “time setting mode” in which the setting of a clocking start initial value is possible by UP and DOWN switches without depending on the operation of a time set switch.

Abstract: A forced flue type combustion device in which an orifice 13 is provided in at least one of an air supply passage 5 and an exhaust passage 6, and in which the existence/nonexistence of a clog is determined on the basis of a detected pressure difference value from a pressure difference sensor 14 for detecting the difference between the pressures on the upstream and downstream sides of the orifice 13, is arranged so that the existence/nonexistence of a clog can be determined with accuracy even during weak combustion with a low rotational speed of the combustion fan 8. Speed increasing processing for increasing the rotational speed of the combustion fan 8 is intermittently executed during weak combustion. During weak combustion, clogging determination processing based on the detected pressure difference value is executed only when the rotational speed of the combustion fan 8 is increased by speed increasing processing.

Abstract: An administration terminal, a communication terminal, a wireless communication system, and a wireless communication method, in which frames can be transmitted/received in excellent communication quality by avoiding interference when an administration terminal and a communication terminal suffer from interference with electronic devices that use the same frequency. Between the administration terminal and the communication terminal, while the reference frequency for transmitting/receiving the reference frame is not changed, the switching is performed into a non-reference frequency different from the reference frequency at least one time within the reference frame interval at the same timing, so that frames can be transmitted/received using one or more frequency including the reference frequency and one or more non-reference frequency.
