Filed: 1993-08-31
Abstract: PURPOSE:To cope with a synchronization deviation even in the case of continuous communication in a half-duplex communication system by setting a predetermined communication cycle, and by comparing the setting with the content on the vacuum cleaner body side at every signal receiving so as to compensate the content. CONSTITUTION:A communication cycle is carried out as follows: a header signal HD indicating the forehead of the cycle is transmitted from a portable control part 3b to a vacuum body 2, then a fan motor control signal M1 is transmitted, and finally, a dust quantity signal M2 is transmitted from the vacuum body 2 to the portable control part 3b. The vacuum body 2 is set so as to obey the communication cycle when the signal HD is received, and if the cycle is deviated between the portable control part 3b and the vacuum body 2 due to an instant power failure, the deviation is compensated on the vacuum body 2 side. When a signal is received by a body side transmitting and receiving means 11, the latter compares the content of the signal with a signal from a body side communication cycle setting means 12. If they are coincident with each other, the next communication cycle is carried out, but if they are not coincident, the communication cycle is set in a standby condition for the signal HD, that is, the communication cycle is stopped until the signal HD is received. When the signal HD is received, the original cycle is carried.

Abstract: PURPOSE:To increase an output as a heat sensor by forming the sensor of a pair of overhang elements made up of an electrically insulative material and so provided as to hang over in the air and heater leads provided on the overhang elements respectively, on a substrate. CONSTITUTION:Heater leads 4 and 5, metal oxide thin films 6 and 7 being heat sensors, and leads 8 and 9 thereof for detection, are formed respectively on two overhang elements 2 and 3 of a substrate 1 which are formed by undercut etching. When a current of about several milliamperes is let to flow through said heater leads, heat sensor elements are heated to about 150 deg.C. The two heat sensors are made to have the same temperature, so that resistance values thereof be equal with each other. An output of a Wheatstone bridge circuit is zero in this state. When air is let to flow in the direction of an arrow to a flow velocity sensor shown in the figure, the heat sensor 6 on the upstream side is cooled and the resistance value is increased, while the temperature of the sensor 7 on the downstream side is increased and the resistance value lowers. When a bridge current of 1mA is impressed, therefore, an output of about 1V is obtained without amplification.
