摘要： A simply configured thermal flowmeter can provide high measurement accuracy over a long period of time by suppressing the characteristics degradation due to adhering contaminants. On the surface of a diaphragm part, a heater resistor is formed. Temperature difference sensors through are disposed on the two sides of the heater resistor (upstream and downstream sides in the flow direction of an air stream). The temperature difference sensors are disposed upstream of the heater resistor while the temperature difference sensors are disposed downstream of the heater resistor. Outside the temperature difference sensors, heating temperature sensors are formed. Control is performed so that the temperature of the heating temperature sensors is set higher than the air stream temperature by a certain degree. Therefore, even if contaminants adhere to the sensor device, the temperature of the heating temperature sensors is held constant. Since the temperature difference sensors to detect the flow rate is located between the heating temperature sensors, the temperature change due to the contamination is small. This suppresses the characteristics degradation, making it possible to provide high measurement accuracy over a long period of time.
摘要翻译：简单配置的热流量计可以通过抑制由于污染物附着引起的特性劣化，从而在长时间内提供高测量精度。在隔膜部件的表面上形成加热电阻器。温差传感器通孔设置在加热电阻器的两侧（气流的流动方向的上游侧和下游侧）。温度差传感器设置在加热电阻器的上游，而温差传感器设置在加热电阻器的下游。在温差传感器之外，形成加热温度传感器。进行控制，使得加热温度传感器的温度被设定为高于气流温度一定程度。因此，即使污染物粘附到传感器装置上，加热温度传感器的温度也保持恒定。由于用于检测流量的温差传感器位于加热温度传感器之间，因污染导致的温度变化小。这抑制了特性劣化，从而可以在长时间内提供高测量精度。

摘要： To reduce power consumption by a thermal flowmeter while good flow-rate detection sensitivity is maintained, it is only necessary to reduce power consumption by a heat resistor under predetermined conditions. Specifically, provided that a width Wh of the heat resistor is between 100 micrometers and 400 micrometers inclusive (100≦Wh≦400), it is only necessary that a relationship among the length Lh of the heat resistor, a temperature increase ΔTh for the heat resistor, and a maximum permissible power Phmax to be supplied to the heat resistor be set so as to satisfy a formula 1.4≦ΔTh·Lh/Phmax≦2.8 in order to maintain good flow-rate detection sensitivity. Accordingly, the length of the heat resistor and the temperature increase in the heat resistor are set so that the maximum power consumption can be reduced within a range in which the formula is satisfied.

摘要： A master unit sends a start signal to a slave unit. When receiving the start signal from the master unit, the slave unit sends, to the master unit, a synchronization field that is a data train (pulse signal) indicative of a transfer clock with which the slave unit is able to perform transferring and receiving operations. The master unit sends, to the slave unit, command data in accordance with the transfer clock indicated by the synchronization field sent from the slave unit. In response to the command data sent from the master unit, the slave unit sends, to the master unit, response data in accordance with the transfer clock indicated by the synchronization field. Thus, in a communication system employing a serial data transferring apparatus of the present invention, the master unit establishes the synchronization for the data transfer, while the slave unit is free from a burden of establishing the synchronization for the data transfer. A serial data transferring apparatus is realized which can simplify the structure of the slave unit, cut the total cost, and reduce noise.
