A signal transmission evaluating apparatus acquires cross talk ratio and type categorized by a relationship between the first transmission path and the second transmission path for each of the pins of the second transmission path. The apparatus computes an occupation ratio of the crosstalk for each of the types with respect to all of the crosstalk supplied to the first transmission path in the connector, and computes a noise source output in the second transmission path on the basis of the occupation ratio for each of the types of crosstalk. And the apparatus computes first transmission path loss and second transmission path loss on the basis of the occupation ratio for each of the types of crosstalk, and computes an amount of received noise of the first transmission path on the basis of the noise source output and the first transmission path loss and the second transmission path loss.

Water contained in cathode effluent from a cathode (1B) of the fuel cell power plant is condensed by a condenser (8) and recovered to a water tank (10). Water in the water tank (10) is supplied from a pump (17) to a humidifier (4) which humidifies hydrogen-rich gas supplied to an anode (1A) via a water passage (9B). When the power plant stops operating, a controller (30) first recovers water in the water passage (9B) to the water tank (10). Also, the freezing probability of the water passage (9B) is determined from the temperature detected by an outside air temperature sensor (31), and a wait time is set according to the freezing probability. By opening a drain valve (15) and draining residual water in the water passage (9B) after the wait time has elapsed, freezing of the water passage (9B) can be prevented with a minimum water drainage amount.

Method and computing apparatus for processing speech signal data. A speech signal is divided into frames. Each frame is characterized by a frame number T representing a unique interval of time. Each speech signal is characterized by a power spectrum with respect to frame T and frequency band ω. A speech segment and a reverberation segment of the speech signal is determined. L filter coefficients W(k) (k=1, 2, . . . , L) respectively corresponding to L frames immediately preceding frame T are computed such that the L filter coefficients minimize a function Φ that is a linear combination of sum of squares of a residual speech power in the reverberation segment and a sum of squares of a subtracted speech power in the speech segment. The computed L filter coefficients are stored within storage media of the computing apparatus.

A connector, which is mounted on a board by applying a solder to terminal leads extending from a connector body, is removed from the board. A heat transfer part is inserted into and attached to the connector. The terminal leads are heated by heating the heat transfer part and melting the solder by heat. Then, the connector is separated from the connector from the board.

A method and related apparatus are disclosed of guaranteeing VIN registration to a vehicle's ECU. A vehicle identifier is entered into a production control system connected to a network. The entered vehicle identifier is compared with an expected vehicle identifier. If a match is obtained between the entered and expected vehicle identifiers, the vehicle identifier is sent from the production control system to a vehicle Immobilizer. A vehicle identifier acknowledgement is received at the production control system from the vehicle Immobilizer. The production control system verifies the vehicle identifier embedded in the acknowledgement. If a match is obtained, an information record associated with the vehicle identifier is sent from the production control system to the vehicle Immobilizer. An information record acknowledgement is received at the production control system from the vehicle Immobilizer. The production control system verifies the information record embedded in the acknowledgement. If a match is obtained, an authorization message is sent from the production control system to the vehicle Immobilizer. The vehicle identifier and the associated information record from the vehicle Immobilizer are written into an electronic control unit incorporated into the vehicle in response to the authorization message. The vehicle Immobilizer then continues to write other data into the vehicle's ECU. After all the writing is complete, the vehicle Immobilizer reads from the vehicle's ECU the vehicle identifier and the information record, and sends them back to the production control system for final verification. If the two pieces of information from the ECU match the two pieces of information held by the production control system, the production control system sends a complete message to the Immobilizer and records the VIN registration record in the central database. Upon receiving the complete message, the Immobilizer resumes to its ready state and the ECU data registration process is complete.

The present invention relates to a microwave heating device, and in particular, a microwave heating device with a microwave heating element mounted on the surface of a heating dish on which food is placed inside a heating chamber. The microwave heating device according to the present invention includes a heating chamber for placing an object to be heated; a magnetron for generating microwaves; a waveguide for supplying the microwaves generated by the magnetron through the bottom of the heating chamber; a heating dish on which the object to be heated is placed; a microwave heating element positioned on the bottom surface of the heating dish to generate heat by absorbing microwaves; and an access passage for allowing the microwaves supplied by the waveguide to reach above the heating dish from below the heating dish. The object on the heating dish is heated by the heating dish, which is heated by the microwave heating element and by microwaves that reach above the heating dish. Therefore, the surface and the inside of the object can be heated in a simple and quick heating operation.

A protocol conversion system is provided to secure a highly reliable and smooth data communication between different two types of networks whose protocols differs in types from each other. A protocol conversion between such networks is realized by replacing headers added to communication data. Information indicating that sending data was success or failure in transmission is included in the headers, thereby sending results being recognized. A serial interface intervenes between the self and party systems in order to detect states of the party system. Further, for data communication, without processing (or terminating) layers up to an application layer, only lower layers, that is, a transport layer and layers lower than it, are processed (or terminated) to raise reliability in data communication.

The inventive clothes dryer is provided with a system for preventing the overheating of the clothes in the drum caused by the abnormality in the V-belt, such as the break or derailment thereof. By the system, the power supply to the motor is halted temporarily while the motor is rotated at a predetermined speed, whereafter the motor keeps rotating due to its inertia. During the inertial rotation of a predetermined period of time, the number of rotations of the motor is counted. When the V-belt is in the normal state, the motor is loaded appropriately, so that the speed of the motor falls rapidly during the inertial rotation, and the number of rotations is accordingly small. When, on the other hand, the V-belt is in an abnormal state, the number of rotations is large. Therefore, the state of the V-belt is checked by comparing the number of rotations to a predetermined value, and when the number is smaller than the predetermined value, the drying operation is stopped.

When characters and the like are written with a writing device, handwriting is detected by a handwriting detection circuit based on outputs from optical sensors and stress sensors and is stored in a handwriting memory section. The handwriting memory section stores the handwriting whereby it can be used as input data for a computer and the like without reductions in the convenience in using the writing device.
