Title: Ac level meter
Inventor: MIKI HIDETANE
IPC: G01R19/00
Filed: 1996-09-25
Abstract: PROBLEM TO BE SOLVED: To provide easily and automatically optimal precharge, by detecting DC level and removing it responding to supply of a stability judging signal. SOLUTION: A transistor Q1 on a DC level removing circuit 11 conducts responding supply of a H level stability judging signal (s), and quickly starts removing DC level of a signal (a) due to a resistor R2. After time t1 which is determined by a time constant of the resistor R2 and a capacitor C1 passes, the level of a signal (c) rapidly decreases, negative DC level appears, and the DC level is supplied to an addition circuit 6. As a result, the addition circuit 6 outputs an addition signal (f) of almost 0 level. Electric potential of the signal (f) decreases within stable level, and a stability judging circuit 7 outputs L level of the stability judging signal (s) responding to the signal (f).  The transistor Q1 blocks responding to L level of the stability judging signal (s) and returns AC level of the signal (a) to the value to be measured by separating the precharged resistor R2 from a joint A. Thus, the precharge is automatically completed in time t1.

Abstract: PURPOSE:To measure the transition of a network load by providing a token counter, a token counter reading part and a control part counting a token packet to the token counter each time the token packet comes cyclically. CONSTITUTION:A loop side control part 13 always supervises the packet to flow in a receiving circuit 11, decides whether it is the packet of its own or not and whether it is the token packet or not, and transfers the packet as it is to a transmitting circuit 12 when it receives a data packet whose destination is not to the control part 13.

The counter reading request of the token counter 18 is outputted form an external system, the counting number of the counter 18 is read from a token counter reading part 19, and it is transferred to the external system. By executing such an operation at a fixed time interval, the transition of the load of the network in such a unit time can be measured.

Abstract: PURPOSE:To accomplish an induction heating cooking apparatus which performs high precision load sensing at low loss and low cost by comparing the amplitude of resonance voltage generated at No.1 and No.2 resonant capacitor with the input current from a DC power supply, and thereupon judging the load. CONSTITUTION:A DC voltage sensing part 9 senses the voltage (VD) of a DC power supply 1, while a resonance voltage sensing part 10 senses the voltage (VC) at the middle point of No.1 and No.2 resonant capacitors 5, 6, and an input current sensing part 11 senses the input current (Iin) from said DC power supply. A load sensing part 12 performs load sensing from the output signals of the named DC voltage sensing part 9, resonance voltage sensing part 10, and input current sensing part 11 and the output proportional to the continuity ratio (D) from a control part 8. A load sensing part 12 calculates VC-VD.D as the sensed voltage, and the result is compared with the input current (Iin). If the sensed voltage is greater than the judgement level, it is judged as the load is miscellaneous, and if smaller it is judged as normally loaded.

Title: Block address correcting circuit
Inventor: YAMAMOTO YOSHIKAZU
IPC: H03M13/27
Filed: 1984-11-30
Abstract: PURPOSE:To make a block address correction stronger by obtaining a majority of a difference signal between an output of a counter and a block address in the input data by a reference block signal and calculating a block address from the decision output. CONSTITUTION:Since a block address code added to a block each has a continuity, the difference between an output of a counter 13 counted up by a reference block signal and a block address in input data DIN is to be a constant value. The difference is obtained by a subtracter circuit 12 and the difference of a block address, to which influences of transmission errors are given, will not be able to go to a prescribed value. Then, by a majority logic circuit 16, the majority of a difference signal which is continuous, for example, concerning five blocks, is obtained, a correct difference is determined. The output of a counter 20 counted up by a block signal to the determining difference is added by an adder circuit 19 and the value of a block address is calculated. Consequently, even when error correcting code processing is not executed to a block address code, the block address can be sufficiently corrected.

Abstract: PURPOSE:To prevent loss due to support and guide of a vibration trestle and to simu late a vibration waveform accurately by floating and supporting a magnetic body yoke which is provided on the lower surface of a vibration trestle with a magnetic force of an electromagnet for floating which is fixed on a floor and then vibrating it with a vibration machine. CONSTITUTION:Vibration which is generated by a vibration machine 3 is transferred to a vibration trestle 1, thus vibrating an object to be vibrated on the trestle 1. In this case, a magnetic body yoke 13 on the lower surface of the trestle 1 is attracted by an electromagnet 11 for floating which is fixed on a floor with a magnetic force, thus floating the trestle 1 without any contact. A gap g is measured by a displacement sensor 14 so that the gap (g) between the yoke 13 and the electromagnet 11 becomes constant and the output is supplied to a controller 15. The controller 15 excites the excitation circuit of the electromagnet 11 so that the magnetic force of the electromagnet 11 and the weight of the trestle 1 where the object to be vibrated is mounted are balanced. Further, by mounting an electromagnet for supporting horizontal direction, the vibration direction can be guided without any contact. Also, by applying a desired waveform to the electromagnet for floating and horizontal guidance, a fine vibration can be simulated.
