Title: Real time control electric power adjusting device
Inventor: GOODON DABURIYU PAARUMAN
IPC: H02M5/257
Filed: 1991-06-18
Abstract: PURPOSE: To stably supply a necessary output by correcting in real time the effects of the input disturbance fluctuation like the distortions of a power waveform, etc. CONSTITUTION: The driving signal of a forward power switch element 311 is turned on via a driving circuit 321, and the driving signal of a reverse power switch element 312 is turned off via a driving circuit 322 before the zero crossing time when the input voltage changes from negative to positive value. A microcomputer 325 reads an output voltage value at fixed interval via an output voltage detection circuit 315 to calculate the execution output voltage, compares the execution output voltage with its target value and reverses the on/off operations of both switch elements 311 and 312 when coincidence is secured between the executing output voltage value and its target value. Thereafter, the microcomputer 325 repeats the reversal of on/off operations between the elements 311 and 312 whenever the target execution output voltage value and its actual result coincide with each other.  Thus the output is stably supplied with no influence of the disturbance fluctuation.

Title: Tone controller
Inventor: HORI FUMIO
IPC: H03G5/00
Filed: 1981-09-16
Abstract: PURPOSE:To prevent oscillation when the tone controlling function is cut off, by connecting independently a changeover switch so that a phase inverse secondary function  LPF and a control circuit are not connected in series when the changeover switch is  switched. CONSTITUTION:A signal is supplied to an input terminal 1 at the positive side of an amplifier 3, and a resistance R1 is connected between an input terminal 2 of the  negative side and an earth. The resistances R2 and R3 are connected in series between  the terminal 2 and an output terminal 4, and the resistances R4 and R5 are connected in series between the terminal 4 and an earth. Thus a feedback circuit is formed for  the amplifier 3. A voltage dividing tone controlling circuit 5 and a phase inverse  secondary function LPF6 can be connected to the feedback circuit independently from  each other by means of the changeover switches SWS1 and S2 having their output  sides interlocking with each other. When the SWS1 and S2 are connected at the side  (a), the gain is controlled at low and high bands to perform the control of sound  volume. The functions of the circuit 5 and the LPF6 are cut off independently by the  SWS1 and S2. As a result, a series connection is avoided between the circuit 5 and the  LPF6 in the switching mode. This can prevent the oscillation that is caused with a peak produced at a specific frequency.

Filed: 1990-06-05
Abstract: PURPOSE:To obtain an R-Fe-B-based permanent magnet whose corrosion- resistant property is excellent by a method wherein a protective layer is constituted of Ni or an Ni alloy which contains one or more kinds of Co and Fe at a specific wt.%. CONSTITUTION:A protective layer on the surface of a permanent magnet which contains R (where R is one or more kinds of rareearth elements including Y), Fe and B and whose main phase is substantially a tetragonal system is constituted of Ni or an Ni alloy which contains one or more kinds (whose total content is within a below-mentioned range even when they are added in a composite manner) of Co and Fe at 0.4 to 3wt.%. Two or more protective layers are formed. When the content of Co and Fe in the protective layers is less than 0.4wt.%, a pinhole is easy to produce, coarse crystal particles in an Ni-plated film are easy to produce and a corrosion-resistant property is not sufficient. It is undesirable when the content exceeds 3wt.% because a stress in the Ni- plated film becomes large and the film is easy to exfoliate.
