摘要： PURPOSE:To provide a magnetic field analyzing method capable of simply analyzing an analytical object such as a rotary machine subjected to skew and made unknown quantity to be not uniform in z direction in a two-dimensional field. CONSTITUTION:At least two or more meshes are prepared (11), non-steady magnetic field analysis (12) is performed regarding at least one unknown quantity as an eddy current by using the two or more prepared meshes, correction calculation (13) for the eddy current obtained as a result of the non-steady magnetic field analysis is executed to calculate an eddy current correction value, and static magnetic field analysis (14) is executed by the use of the eddy current correction value and the two or more meshes. Consequently, the analysis of a rotary machine considering a skew which can not be executed by a conventional method can be simply executed by two-dimensional magnetic field analysis and a magnetic field of a rotary machine subjected to skew such as an induction motor can be numerically calculated.

摘要： PURPOSE:To calculate the secondary current of an induction motor in a short time and with high precision by calculating the secondary current from, while time, position and phase are considered, the secondary currents flowing in secondary coils extracted by an secondary current extracting means. CONSTITUTION:Slip (s) of the rotor in magnetic field analysis is represented in an equation based on multiple ns of primary current time cycle (integer), rotor slot numbers NS2(2P) (integer) per two poles of to-be-analyzed machine and rotor slot numbers N2t (integer) delayed in rotating from cycle speed of magnetic field generated by a stator coil during ns times of primary current time cycle. The time amount of magnetic field analysis time interval is set to at least ns times of primary current time cycle, and the secondary current generated at each rotor coil in the analysis time interval is synthesized in time series in synchronous to the movement state of the rotor slots, so that the amount of one cycle of secondary current is calculated and displayed.

摘要： PURPOSE:To inform a user of reception even in the case of a FAX which is produced by a different maker and is already installed by reporting the presence or the absence of the delivery destination of a reception document or a FAX reception message selected from the status of the pertinent user. CONSTITUTION:A main control part 3 of a FAX server 1 controls a LAN control part 7 which transmits and receives data through a LAN 12, a communication control part 8 which communicates document data with a FAX of the other party through a public line 13, a delivery information detecting part 9, a user management part 10, and a document management part 11 which controls write and read of document data. The status of each user, correspondence relations between delivery destinations and user names, group names to which users belong, and security information are stored in a user management file 6. The delivery information detecting part 9 extracts the delivery destination from communication procedure information or reception document data from the FAX of the other party, and the user management part 10 retrieves the destination user extracted by the delivery information detecting part 9 from the user management file 6 and sends the FAX reception message to a client 2.

摘要： PURPOSE:To enhance the ciphering of confidential reception more than that of a conventional equipment by realizing a confidential reception function not requiring a picture memory with respect to the facsimile equipment not especially provided with the picture memory. CONSTITUTION:Ciphering specific to a facsimile equipment receiving picture information is applied to the picture information sent together with a password through confidentiality and the result is printed out (103,104). An original on which compression picture information ciphered with a password added thereto is printed out is read from the facsimile equipment and when the password and a password inputted (115) by a recipient are discriminated to be coincident (116), read compressed picture information is decoded and printed out (119, 120).

摘要： PURPOSE:To allow the user to improve the job efficiency by displaying a message stored in an operating message storage section and registering a parameter to a setting function storage section when the parameter required for a service function. CONSTITUTION:When the user sets a service function in use, an operation information input section 11 displays a message stored in a message storage section 12 sequentially on an operation panel. The user commands whether or not a service function corresponding to the displayed message is in use by depressing a YES key or a NO key. When the user depresses the YES key and enters a parameter required for the said service function, an input section 11 registers the said service function and the required parameter to a setting function storage section 10. When the input section 10 displays all messages in the storage section 12 and the user completes all the service functions, the communication using the service function is executed based on the information registered in the storage section 10.

摘要： PURPOSE:To eliminate a data wait time at a receiver from a transmitter by sending a line whose compression processing is finished from the transmitter at a predicted point of time when unanalyzed lines in the receiver reaches a prescribed number or below. CONSTITUTION:A receiver unanalyzed line prediction section 8 predicts number of lines not yet analyzed by the receiver in a sent picture data and stores the number to an unanalyzed line number storage section 10. When a value of the unanalyzed line number storage section 10 reaches a preset line number separately or below before a compression processing section 3 generates a compression data of a quantity corresponding to a data length of one frame, a frame transmission control section 7 sends the compression data generated so far as a CDUI(Command Document User Information) short frame (cdui frame) not over a data length of one frame. Thus, the time of awaiting the reception of a picture data without expansion recording for the receiver is minimized to reduce the communication time.

摘要： PURPOSE:To allow the sender side user to fulfill the object with one transmission procedure by using a printer of a transfer destination facsimile equipment at hand and registered in advance in place of a printer of a facsimile equipment whose paper supply is in shortage. CONSTITUTION:A number of a transfer destination facsimile equipment to print a received original in the paper shortage is registered in advance by the user. When a control section 1 detects a paper shortage signal 15, a transmission reception selection signal 18 throws a switch 11 to the position of a terminal E and a switch 12 to the position of a terminal C to cause the transmission wait standing state, and further, a mode selection signal 17 is used to connect terminals G, I of a switch 10 and the input is sent to a transfer number storage device 3. After the changeover of the switches 10, 11, 12 the control section 1 reads the number of the transfer destination facsimile equipment of the trans fer number storage device 3 is read from the terminal G and outputted to the terminal E via the terminal 1. A transmitter 6 generates a dial signal based on the transfer number inputted to the terminal E and sent to a line 8 via the terminal C to call the transfer destination facsimile equipment.

SOLUTION: The refrigeration cycle device has the refrigeration cycle composed by sequentially connecting a compressor 130, a condenser 140, a condenser air blower 145, a evaporator 150 and an expansion valve 160. The refrigeration cycle device comprises: the motor that drives the compressor 130, is formed with a basket-shaped winding 110 at the external periphery of a rotor, and embedded with permanent magnets magnetized to a plurality of poles inside the winding; and an operation current detection means 180 that detects an operation current of the motor. The refrigeration device obtains a value related to the distortion of the operation current, and when the value is not higher than a set value, electricity applied to the motor is cut.
