Title: Controlling device of rotary electric machine
Inventor: ASHIKAGA TADASHI
IPC: H02P23/00
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To obtain an output torque accurately corresponding to a torque command even if temperature increases by calculating a torque current command from a magnetic flux which is obtained from a magnetic flux table based on a temperature detected by a temperature sensor and a torque command and controlling a rotary electric machine from the torque current command. SOLUTION: A magnetic flux table 21 is a data table for storing the demagnetization characteristics of magnetic flux according to a temperature created, for example, by the data sheet of the permanent magnet of a PM motor 2, a motor stator temperature is detected by such a temperature sensor as a thermistor, and a temperature 6mg of the permanent magnet at a rotor side is supplied as a substitution for temperature information. As a result, a magnetic flux table 21 transmits the information on the magnetic flux Amg corresponding to a temperature tmg. A part 22 for setting the number of poles multiplies the magnetic flux Amg by the number of poles before outputting. A divider divides a torque command T* by the output of the part 22 for setting the number of poles.  The output of a divider 23 becomes T*/Pn Amg and a torque current command becomes Ig, thus compensating the demagnetization characteristics due to temperature increase and obtaining a desired torque.

Title: Frost detecting method
Inventor: SUZUKI CHIYUUJI
IPC: G01N21/59
Filed: 1981-05-20
Abstract: PURPOSE:To prevent variance in detection due to drops of water formed during defrosting by using the output of a photodetecting element in a frozen state at a certain time after the defrosting as a reference, and then detecting the amount of relative variation from the reference level. CONSTITUTION:When a power source is turned on while no frost sticks to a cooling fin 4 fitted to a refrigerant pipe 3, light from a light emitting element 1 is received by a photodetecting element 2, whose output is converted into a digital signal by an A/D converting circuit before being inputted to a microprocessor 7. In the microprocessor 7, a timer means makes an advance in operation and the signal from a frost sensor circuit 5 is not stored until a certain time elapses after the power source is turned on. During this constant time, the frosting condition of the optical window part of the frost sensor is stabilized by freezing drops of water. After said constant time, the signal from the frost sensor circuit 5 is stored as a reference level in the storage means of the microprocessor 7. Then, the signal from the frost sensor circuit 5 is compred with the reference level at prescribed intervals of time to detect the presence of frost.

Title: Length-breadth converter
Inventor: SUGIURA SUSUMU
IPC: B41J2/485
Filed: 1982-05-11
Abstract: PURPOSE:To reduce the memory capacity remarkably and to attain ease of control, by writing data in a buffer memory continuously in the order of addresses, and reading out the data in the order of addresses added with a recording head scanning words' share based on the initial address. CONSTITUTION:The buffer memory BM storing a bit pattern data is 128X2048 bits, where the number of nozzles of the recording head is assumed as 128, the moving distance as 256mm. and the nozzle pels as 8. Since the value of a counter CNT represents the column address of the memory BM and the value of a latch circuit LAT indicates the line address, the address goes to 127 when the value of the circuit CNT is 127 and the value of the circuit LAT is 0, and goes to 128 when the value of the CNT is 0 and the value of the LAT is 0. Thus, the designation address at reading is a continuous address started from 0. The designation address starts from the address 0 at the readout from the memory BM and after the values of the CPU internal registers X and RP are subtracted and added by one respectively and the circuit LAT is advanced; this operation is repeated. Thus, the designation of the readout address is executed at each 128 words, by using 0 as the reference.

Title: Route high speed changeover method and router
Inventor: TSUKAGOSHI MASAHITO
IPC: H04L69/40
Filed: 1994-03-24
Abstract: PURPOSE:To reduce considerably a time switched to a backup route after the occurrence of a fault in the router in a network system having a redundant route between LANs and to switch a route at a high speed by having only to mount an additional function to the router without imposing any modification onto a communication terminal equipment. CONSTITUTION:Routers 1, 3 and routers 2, 4 being respectively in backup relation in a route between LANs 7 and 8 send periodically a monitor packet for mutual monitor with each other at an interval shorter than an interval of routing protocol packets in addition to the routing protocol packet for generating a routing table. Thus, the switching time to the backup route on the occurrence of a fault in a router is considerably reduced more than the case with using only a standard routing protocol such as RIP by means of the mutual monitor using the monitor packet. Furthermore, since this method does not give effect on the standard protocol, the effect is obtained without needing revision of an existing communication terminal equipment at all.

Title: Cutting method for corrugated member and device thereof
Inventor: NOZAKI KIMIO
IPC: B23D23/00
Filed: 1987-03-30
Abstract: PURPOSE:To enable good cutting at all times as well as to prolong service life for a cutting upper tool, by installing two fluid spray nozzles in front and in the rear sides of the cutting upper tool, making this upper tool go down while widening the pitch interval of a corrugate member, and cutting this widened part into the specified length. CONSTITUTION:Two fluid spray nozzles 51 and 53 are installed in front and in the rear sides of a cutting upper tool 23, making the sprayed fluid so as to be crossed on the extension of a tool surface 27, and thereby these nozzles 51 and 53 also go down with the lowering of the upper tool 23, therefore a corrugate fine 35 being situated in an intersection point of the sprayed fluid is extended wider, thus a widened part 59 is cut by the upper tool 23. In this case, if the upper tool 23 goes down up to the specified position, a limit switch comes on, a solenoid valve 61 of a fluid feed pipe 49 is opened, and air is fed out of a compression pump 47. Accordingly, at the time of the upper tool 23 lowering, even if a trough part of the corrugate fin 35 gets out of position just under the tool surface 27 more or less, good cutting is possible, and since excessive force will not act on the upper tool 23, its service life is prolonged.
