Abstract: PURPOSE:To perform accurate detection by providing a constitution wherein a reference voltage forming part is similar to a detecting part. CONSTITUTION:A first-reference-voltage forming part 40 rectifies and smoothes a pulsating current Vs from an oscillating part, and a reference voltage for detecting wire breakdown is obtained. The DC voltage component is removed from the voltage Vs with a capacitor 41. The voltage is sent into a voltage dividing circuit 40a. Since an intermediate voltage Vm is supplied to one end, a sine wave pulsating voltage Vp is generated at a connecting point P. The voltage Vp is inputted to the non-inverted input terminal of an operation amplifier 44 of a peak hold circuit 40b. A power source voltage Vo is imparted to the output terminal. A negative peak voltage is held with a capacitor 48 to which the voltage Vo is imparted through a large resistor 49. The voltage can be updated and supplied as a first reference voltage Vr1. In this way, the fluctuation of the power source voltage and the temperature change can be compensated, and the accurate detection of the leaked liquid can be performed.

Title: Formation of electrodeposited film, formation of electrode and electrodeposited film forming device
Inventor: TATSUURA SATOSHI
IPC: C25D5/02
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To efficiently form an electrodeposited film with high quality with lower energy consumption by irradiating the surface of an object to be treated with pulse lasers of a pico second or below to excite nearly only the electrons and forming a non-equilibrium state of temperature or energy between electrons and lattice. SOLUTION: The object 10 to be treated is immersed into an electrolyte solution and is irradiated with the femtosecond laser in the state of impressing bias voltage to a conductive film 12. The time for several picoseconds or above is needed in order for the electrons and lattice to attain a temperature equilibrium state and, therefore, the non-equilibrium state is achieved near the surface of the conductive film 12 during the irradiation with the laser and hot electrons are generated. Consequently, the Pt, Zn, etc. in the electrolyte solution are plated to the portions irradiated with the laser on the surface of the conductive film 12 where the hot electrons are generated.  At this time, the energy of the irradiation with the laser is completely applied to the electrons and the unnecessary lattice vibration = heat is not induced and, therefore, a temperature gradient does not arise at the edge portions of the plating and the generation of a sag is suppressed.

Abstract: PURPOSE:To facilitate the handling of the system without the need for any special electrode equipment parts and attaching and detaching operations by making up an electric circuit through suspending healds with two carrier rods as anode and cathode, respectively. CONSTITUTION:An electric circuit is made up by suspending healds 6a and 6b with carrier rods 4 and 5 as anode and cathode, respectively. The heald 6a fallen due to yarn breakage etc. comes into contact with the head 4b of the carrier rod 4, enabling current injection.

The heald 6b cannot come into contact with the head 4b of the carrier rod 4; therefore, the electric circuit is put to 'off' state.

IPC: H04N5/10
Filed: 1995-06-02
Abstract: PURPOSE: To provide a stable vertical synchronizing separator circuit by reducing the amplitude of a noise component and preventing the malfunction of an integrating operation by narrowing the pass band of a variable low-pass filter under a weak electric field. CONSTITUTION: In the case of inputting a video signal 1a under the weak electric field, an electric field detection circuit 4 adds the size of a pedestal level while using an adder 41 during the period of an electric field gate signal 41 showing timing to perform electric field detection. Next, the average value of pedestal levels is calculated by an average circuit 42 and compared with the size of an electric field level 43a by a comparator 43. In the case of weak electric field, the noise is integrated and the average level 42 becomes a larger value than ordinary electric field time. Therefore, by setting the electric field level 43a at a value higher than the pedestal level in the ordinary electric field and optimum for a system, a switch signal 4b at the time of weak electric field is outputted.  At a variable low-pass filter circuit 3, the pass band of the input video signal 1a is narrowed by the signal 4b and the noise component is removed so that the malfunction of synchronous slice can be prevented.
