A heat receiver includes a casing defining a flow passage on a thermal conductive plate. The thermal conductive plate is received on an electronic component. The thermal conductive plate serves to transfer heat to coolant in the flow passage. At least two inflow nozzles extend into the casing to have discharge openings opposed to the upstream end of the flow passage. The coolant flows into the flow passage through the inflow nozzles. At least two streams of the coolant are thus generated in the flow passage. The streams widely expand or spread in the flow passage. The coolant flows through the flow passage without stagnating. The coolant can thus absorb the heat of the thermal conductive plate in an efficient manner. This results in an efficient heat absorption of the heat receiver.

An outdoor unit of a transmitter-receiver apparatus notifies an indoor unit of normal operation by transmitting an unmodulated carrier to the indoor unit via a cable when operation is normal, notifies the indoor unit of an abnormality by transmitting a monitor signal, which is obtained by modulating a carrier by alarm data, to the indoor unit when operation is abnormal, and restores the carrier to the unmodulated state at recovery from the abnormality. Further, the indoor unit transmits an unmodulated carrier to the outdoor unit via the cable if it is unnecessary to send a control signal, and transmits a modulated control signal, which is obtained by modulating a carrier by control data, to the outdoor unit via the cable if it is necessary to send a control signal. As a result, phase noise and the characteristic of spuriousness in the vicinity of the local oscillation frequency are unaffected even if the unmodulated carrier leaks into the reference frequency signal system. As a result, no deterioration is caused in the quality of the communication system.

A mounted circuit substrate has at least one conductive layer. The side faces of a component mounting pad is formed on a surface of the substrate, and includes at least a columnar pattern made of a metal highly resistant to erosion by solder. The side faces of the component mounting pad are completely covered with an organic insulating layer. Therefore, the component mounting pad can withstand molten solder stresses accompanying component replacement even when component replacement is done many times.

A plurality of dummy bit lines are disposed together with a plurality of bit line pairs in a memory cell array. In selectively driving a memory cell connected to the bit line pair, a timing control circuit controls the timing of the driving operation, based on signal change in the plural dummy bit lines, thereby detecting the influences of the process variation in a plurality of positions in the memory cell array. Thus, the influence of the process variation given to the operation of a semiconductor memory device can be further alleviated, compared with the case when one dummy bit line is used.

A semantic recognition system of the present invention provides a user interface capable of receiving speech input to a user and an application interface that conveys an input content of the user to an application. The semantic recognition system includes a speech signal input part for receiving input speech signals, a speech recognizer for recognizing a corresponding word based on the input speech signals, a recognized word-semantic number converter including a semantic number-registered word list indicating the correspondence between a semantic number representing a meaning of a word and a registered word belonging to the semantic number, an application interface and an application handling the semantic numbers as data. The corresponding word is recognized by the speech recognizer, based on the speech signals input to the speech signal input part. The recognized word is converted to a corresponding semantic number by the recognized word-semantic number converter. The converted semantic number is notified to the application via the application interface.
