Abstract: An object is to perform discharge of a capacitor using a motor without rotating the motor even when connected to a position sensorless motor. The motor drive apparatus calculates a voltage pulse width at which a motor does not rotate or vibrate using a both-end voltage of a smoothing capacitor and an inductance estimation value of the motor, and applies a voltage with the voltage pulse width to the motor to calculate an inductance. Then, a rotor position is estimated using the inductances calculated for individual switching patterns. A motor current is caused to flow on the basis of the estimated rotor position to perform discharge of charge accumulated in the smoothing capacitor.

Abstract: A refrigerant heating performance is increased while suppressing an increase in weight or cost. A vehicle air-conditioning device (10) is provided with a heat pump cycle (16) for heating operation in which an electric compressor (50) for compressing refrigerant, a vehicle-cabin-interior condenser (26), a throttle (52), and a vehicle-cabin-exterior heat exchanger (54) are connected in that order via refrigerant piping. An inverter for the electric compressor (50) in which a power element comprising a highly heat-resistant semiconductor device is used is disposed on the electric compressor (50) so that the refrigerant compressed by the electric compressor (50) can be heated by the power element. During heating operation of the heat pump cycle (16), the refrigerant is heated by the power element.

Abstract: A terminal uses a web application to control a printer on a network. The web application includes an API that permits the terminal to send instruction and inquiries to the printer over the network. The terminal submits, to the API, the printer's IP address and instructions for defining a print document or printer commands. The API then sends the print document or printer commands to the printer in accordance with the IP address. In this manner, the terminal can request status updates without sending a print job to the printer. The terminal sets the printer's ID address, identifies a type of status event inquiry, and submits the inquiry to receive the printer's current status related to the identified status event. To submit a print job, the terminal creates a print document using the API, sets the printer's ID address, and sends the print document as a print job to be printed.

In redirection control, the print control unit 320 sends the print data and additional information to the second printing device. The additional information includes status information causing the second printing device to print the status of the first printing device.

Abstract: A script language compatible with HTML is used to define methods or objects capable of communicating directly with an intelligent module for printing operations without going through a web browser's print selection option. A print API library provides the needed methods/objects for embedding into a web page. The intelligent module may be a stand-alone electronic device, or may be an intelligent device incorporated into a printer. The intelligent module may manage multiple printers directly or through a network, and it functions to provide a communication bridge for translating/conveying communication between the print APIs on a web page and a target printer. The print API knows the fixed IP address of the intelligent module, and define a print document or print commands and send it directly to the intelligent module by means of the known IP address.

Abstract: An information distribution system reduces the effort required to change an application in conjunction with changes in process content and changes in the receiver type or specifications while also accommodating broadcast processes. A style sheet database stores a plurality of output style sheets, which are information conversion rules including conditional expressions related to information distribution. An integrated device control service acquires output data and receiver information specifying the address of the receiver and the output style sheet corresponding to said receiver. When the output data satisfies the conditional expression contained in the output style sheet, the integrated device control service distributes converted output data, which is the output data converted based on the output style sheet, to the address of the receiver.
