Ground fault detection apparatus

The present invention provides a technique, by speech input, to specify a location, even when a name or the like of the location is not accurately known, while driving. An in-vehicle apparatus mounted in a vehicle has a speech recognition function, and stores information shown on a signboard and a noun substitute in storage. If speech inputted from a speech input device includes a noun substitute and further includes at least a part of the information shown on the signboard, a response is decided according to the information shown on the signboard, and the decided response is outputted from an output device.

In-vehicle apparatus

It is provided a speech recognition system installed in a terminal coupled to a server via a network. The terminal holds map data including a landmark. The speech recognition system manages recognition data including a word corresponding to a name of the landmark, and sends update area information and updated time to the server. The server generates, when recognition data of the area of the update area information sent from the terminal has been changed after updated time, difference data between latest recognition data and recognition data of the update area information at a time of the updated time, and sends the generated difference data and map data of the update area information to the terminal. The terminal updates the map data based on the map data sent from the server. The speech recognition system updates the recognition data managed by the terminal based on the difference data.

Speech recognition system and data updating method

Provided is an information retrieval method including: retrieving, by a computer, a name including input characters from a database for storing the name, an attribute word associated with the name, and a degree of relevance between the name and the attribute word; outputting the retrieved name as a candidate name; and extracting an attribute word associated with the candidate name, the extracting including: calculating a degree of independency indicating a degree of difference between the extracted attribute words, a degree of coverage indicating an extent to which the combination of the extracted attribute words covers the candidate names, and a degree of equality of a number of corresponding candidate names for each attribute word; and calculating a score of the combination of the attribute words based on at least one of the independency, the coverage and the equality to output the combinations of the attribute words to an output unit.

Information retrieval apparatus, information retrieval system, and information retrieval method

On a computer, components forming a development subject are arranged on a scenario editor by using basic component parts, and the component data are set. And a procedure call sequence is defined by specifying procedures of defined components in order of call. The call sequence data is generated in the computer as scenario data. Then, the defined group of scenarios are selected and reflected on the model editor. A whole requirement is created. At that time, a procedure name to be called subsequently on the connection line between components is acquired from the defined procedure sequence data, and a program for effecting animation is generated. Finally, by executing the generated animation program, the procedure call sequence is displayed in an animation form and the requirement is created. By interactive operation alone of the screen using the scenario editor and the model editor, therefore, the requirement of the development subject from the customer can be easily acquired and the whole requirement can be created.

Method for inputting and acquiring requirement

When a brushless motor is rotated at low speeds (the answer of a step S12 is YES), the brushless motor is driven by exciting a first phase coil, a second phase coil and a third phase coil by a sine wave PWM system having a phase difference of 120.degree. from each other to perform a torque control. Since the crest value of the sine wave is controlled in response to torque greatly fluctuated by a load, an out-of-phase phenomenon which is apt to occur at low rotational speeds can be previously prevented. When the brushless motor is rotated at high speeds (the answer of the step S12 is NO), the brushless motor is driven by a square wave PWM system based on a three-phase 120.degree. conduction type. Since the out-of-phase phenomenon is apt to occur as a frequency is increased when the brushless motor is driven by the sine wave PWM system, the control system is switched to a square wave PWM system to prevent the out-of-phase phenomenon. Therefore, the brushless motor can be driven smoothly without much pulsating torque over the full range of revolutions from a low speed (zero revolution) to high speeds (several tens of thousands of revolutions/min).

Motor-driving circuit

In an animation generating method wherein a component of an apparatus to be designed is defined by an instance of an object-oriented program and a figure is allocated to said instance on a computer, and further an animation method for varying a representation of said figure in connection with the operation of the instance is interactively generated, a designation is made of either a slot of said instance, or a method argument of a method effected to said instance, and further a designation is made of a figure attribute of a figure to be changed in an animation representation. In response to this, an animation method for changing the figure attribute is automatically generated with refererence to the slot of the instance, or the method argument of the method effected to the instance.

Animation generating method in a design supporting system

An invert rectifier is provided in which: cooling medium vapor sent from the evaporator is contacted with a weak solution sent from the regeneration unit, and the temperature of cooling medium vapor and the vapor component of absorbent are increased by the action of invert rectification, so that the enthalpy of cooling medium vapor supplied to the vapor-liquid mixer is enhanced. In this invert rectifier, cooling medium vapor is introduced to a lower portion of the container and a residual portion of the weak solution or all weak solution is introduced to an upper portion of the vapor-liquid mixer 16, so that the introduced cooling medium vapor and weak solution are subjected to vapor-liquid contact by the action of an opposed flow. Due to the foregoing, cooling medium vapor is generated, the temperature of which is high, and the amount of the vapor component of absorbent of which is large, so that the enthalpy of cooling medium vapor is enhanced. Even when the thus obtained cooling medium vapor is mixed with a weak solution in the vapor-liquid mixer 16, the temperature is seldom lowered in the mixing process, and an amount of heat exchange in the absorption regeneration heat exchanging section is increased, and the result coefficient is enhanced.

Absorption type heat pump

A process for architecting a figure input/output interface of an instance is provided in an object-oriented design supporting system or the like. An applicable graphic editor is provided with a figure editor, which expands a function for defining a method to draw a user figure and also a function for defining a slot of a figure attribute when the user figure is designated; and furthermore expands a function to produce an instance when the user figure is drawn and also a function for coupling the instances when the figures are connected with each other. Then, input/output figures of a design component are defined and inputted with employment of this applicable graphic editor. In the output, a slot of the displayed instance is updated and then a display is deformed. As a result, the formation of the figure input/output for the instance such as the design component is available by only operating the screen of the applicable graphic editor. According to another aspect, a user figure corresponding to a class is formed by operating a screen of a figure editor, whereby a connection point and a slot of a figure attribute is designated. As a result, a program for inputting/outputting a figure, coupling the figures and deforming the displayed figure is automatically produced, so that it is possible to input a figure of an instance, couple the instances by the figure connections and to realize an animation description by updating the slot of the instance.
