IPC: H05B41/24
Filed: 1978-06-05
Abstract: PURPOSE:To improve reliability, by positively protecting output stage switching elements by wave-form shaping original rectangular wave signals in the switching elements of a power circuit and by driving the elements by rectangular wave signals that an interval is mounted between signals. CONSTITUTION:Signals from a TTL oscillation circuit 7 are wave-form shaped to original rectangular wave signals and the inversion signals by means of wave- form shaping circuits 9, 10 through a binary counter 8, each delay signal is AND composed and output signals g, h are obtained. The signals are input to drive circuits 12, 12' to drive a power circuit shown in the figure produced by connecting a fluorescent discharge tube 6 to the nodes of power transistors 1, 2;3, 4. Consequently, the power transistors 1, 2 or 3, 4 are not simultaneously brought to conductive condition because the power circuit is driven by rectangular wave signals i, j that an interval is mounted so that the signals not each be stacked, and the transistors are not broken by dead short-circuit, thus positively protecting the transistors.

IPC: A47L9/24
Filed: 1978-06-05
Abstract: PURPOSE: To easily hold a cord of an electromotive suction tool for floors, to make the adjustment of sucking force impossible during the time when using the suction tool and to prevent the loading of dust to a hose, etc., by disposing a sucking force adjusting ring near a cord metal clasp of the suction tool, and by fitting the ring to a suction pipe in a revolution-free shape.  
     CONSTITUTION: When an approximate U-shaped groove 17 of a sucking force adjusting ring 10 and a cord guide portion of a cord guide plate 13 agree, a hole 16 for adjusting sucking force is brought to a totally-enclosed condition. When the adjusting ring 10 intends to turn during the time when using an electromotive inlet for floors, the adjusting ring 10 is returned to the original location by the elasticity of a power source cord 8 because an end portion of the cord guide plate 13 is located near the ring and the cord 8 is located at a fixed position. Thus, the adjusting hole 16 is hermetically sealed all the time, and the loading of dust in a hose, etc. causing the lowering of sucking force can be prevented.

Title: Fault tracing method and fault tracing device for realizing the method
Inventor: TANAKA YASUHIRO
IPC: H04L69/40
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To surely trace important fault information such as the number of times of generating faults and the fault generation time, to cancel tracing suppression in the case that fault generation is stopped for fixed time and to accurately provide conditions at the time of starting the tracing suppression again by suppressing fault contents to be traced in the case that the fault is repeatedly and continuously generated. SOLUTION: A fault tracing identification part 5 outputs the fault information to a tracing suppression part 6 in the case of judging that the fault generated in an ATM communication system is the fault to be traced. A tracing suppression control part 6 judges whether or not the fault is during the tracing suppression, and in the case that it is during the tracing suppression, traces the fault code, the number of times of generation and generation time of the generated fault without tracing all the fault information of the generated fault by controlling a monitoring timer 7. Thus, without filling up a tracing area even for the frequently generated fault, generation tendency is recognized and a fault generation cause is easily investigated.

Abstract: PROBLEM TO BE SOLVED: To provide a power unit which can start the supply of high-frequency power to load immediately after power, even through it is equipped with a partial smoothing circuit. SOLUTION: A current flowing to the primary winding of the drive transformer CT1 for driving transformers Q1 and Q2 is inverted by the resonance action of a resonance circuit including an inductor L1 and a capacitor C2, and both transistors Q1 and Q2 are turned on and off alternately by self-excited oscillation. The transistor Q2 constitutes a boosting chopper circuit together with a smoothing capacitor C1, an inductor L2, and a diode D3. The primary winding of the driving transformer CT is inserted into a course, which lets a charge current flow into the smoothing capacitor C1 when transistor Q2 is turned on.  When the power is made, the transistor Q2 is turned on, and at this time the charge current of the smoothing capacitor C1 flows into the primary winding of the driving transformer CT, so that turning on and off of the transistors Q1 and Q2 are started without waiting for the voltage rise of the smoothing capacitor C1.
