摘要： PURPOSE:To improve the controllability with an inexpensive construction by generating a phase output pulse on the basis of an output voltage value, the phase output pulse generating interval and the instantaneous value of the basic wave in the phase output phase of the phase output pulse. CONSTITUTION:An output voltage setter 12 inputs the pattern of the output voltage value of an inverter in response to the operating purpose according to the speed set value inputted through a lamp circuit 12. A frequency divider 14 divides the frequency of a pulse train from an oscillator 13, and outputs a pulse train in response to the interval of the phase output pulse contained in the basic wave. A pulse interval measuring circuit 15 measured the pulse interval of the pulse train from the divider 14, and outputs the measured result. These outputs are inputted to a calculation processor 17, which outputs a pulse width data. A waveform processor 20 sequentially outputs phase output pulse train by the pulse width data and the width pulse signal from a pulse width converter 19.

摘要： PROBLEM TO BE SOLVED: To compress a memory capacity for dynamic content storage. SOLUTION: A dynamic content storage/restoration device (dynamic content storage/restoration proxy device 3) includes: a first storage means (33) for storing a template described with fixed character string data filling variable data; and a second storage means (34) for storing difference data being a difference between the template and dynamic content being a response to a content request from terminal equipment (1, 2). Whether a template is applicable to the dynamic content is verified, and when it is determined that the template is applicable, the difference data is stored in the second storage means, and in response to a restoration request from the terminal equipment, the template stored in the first storage means are combined with the difference data stored in the second storage means, so that the dynamic content is restored.

摘要： PROBLEM TO BE SOLVED: To provide a controller for a PWM power converter which suppresses waveform distortion of a current, even when the pulse width of a command PWM(pulse-width modulation) becomes narrower. SOLUTION: A controller detects the difference in level between a command PWM signal held by a pulse holding section 21 and a phase voltage level signal Uf by means of an error detecting section 22, and the error time is measured and stored at both turn-on time and turn-off time, by means of the counting function of a pulse correcting section 23. Then the controller corrects the turn on/off timings of the held PWM signal by the time corresponding to the stored error amount and outputs the corrected signal as a corrected PWM signal (Uc).

摘要： PROBLEM TO BE SOLVED: To enable reduction in size and price by filling a packaged resin molded case with resin-sealing material, to integrally seal the packaged resin molded case and circuit components, such as semiconductor devices mounted therein. SOLUTION: In a device the resin portion of packaged resin molded case 30 and the peripheral portion of a metal base 15 bonded together using adhesive or the like and further a lead frame 13, semiconductor devices 11a and 11b, a main terminal 17 and a control terminal 24 are electrically connected with one another using metal wires 16. After all the components are mounted on the metal base 15 of the module, resin-sealing material 32, such as epoxy, is placed on the top of the components and thus the semiconductor module is of molded structure, wherein it is integrated with the packaged resin molded case 30. A sufficient quantity of the resin-sealing material 32 for covering and concealing the components 11a and 11b and the metal wires 16 mounted on the lead frame 13 in the module is only required. As a result, the module can be reduced in size and price.

摘要： PROBLEM TO BE SOLVED: To perform the optimum operation suitable for the load condition of an inverter without providing any complicated peripheral circuits by dispensing with a speed command input terminal of the inverter. SOLUTION: When the speed of the operation is set in advance from a console CONS according to the load condition by an inverter INV, the set data are stored in the memory in a microcomputer MCU, and the operation program is stored. The load condition of the inverter is detected by current detecting means CT1, CT2, and incorporated in the microcomputer MCU. The inverter is provided with FW and COM terminals as the operation command input terminal, and the operation is started by inputting the signal therein. The inverter itself determines the pattern for the operation according to the load condition, and the full automatic operation is performed only by connecting an external operation command means to the starting command terminals FW and COM terminals.

摘要： PURPOSE: To output sufficient torque even in the case of regenerative operation by correcting a frequency command on the output of a regenerative discriminating part. CONSTITUTION: The input of a controller into an integrator 11 is not command angular frequency ω, but the second command frequency ω' which is the output of a frequency correction part 10 for correcting the command angular frequency ω. The frequency correction part 10 consists of a regenerative discriminating part 6 for detecting, from the command angular frequency ω and torque correct Iq, that an induction machine is in a regenerative state, a correction quantity output part 7 for outputting the correcting quantity proportional to the torque current Iq, a switching device 9 for outputting the output of the correction quantity output part 7 only in the case of regenerative operation on the output of the regenerative discriminating part 6, and a subtracter 8 for subtracting the output of the switching device 9 from the command angular frequency ω. When the induction machine is in a regenerative state, the quantity obtained by subtracting the correction quantity proportional to the torque current Iq from the command angular frequency ω is inputted into the integrator 11. It is thus possible to output sufficient torque even in the case of regenerative operation.

摘要： PURPOSE:To automatically form acceleration and deceleration ratios without stopping an inverter by controlling a frequency of the inverter by an output of a fuzzy controller which inputs two amounts of a difference of a limited value and a detected value and a change amount of the difference. CONSTITUTION:An acceleration and deceleration controller 93 briefly has an acceleration controller 931, a deceleration controller 932 and a steady controller 933. The controller 931 has a steady accelerator 931a with a fuzzy protection and a fuzzy automatic accelerator 931b, and the controller 932 has a steady accelerator 932a with a fuzzy protection and a fuzzy automatic decelerator 932b. The controller 931 is selected by a SW3 to be executed when a set frequency fr is larger than a command frequency f1 to so decide an acceleration rate that a current detected value IM does not become the vicinity or more of a current limiting value IlimA to accelerate it. The controller 932 is executed when the frequency fr is small to so decide a deceleration rate that the value IM is the vicinity or more of the current limiting value and the voltage detected value ED does not exceed the vicinity of the value Vlim to decelerate it.
