Title: Electrolytic cell for producing metal
Inventor: MAEHARA KUNIO
IPC: C25C7/02
Filed: 1989-03-30
Abstract: PURPOSE:To obtain the electrolytic cell for producing metal in which the metal constituting the electrolytic bath and gaseous halogens are surely separated and collected by forming at least one of bipolar electrodes so that the flow passage cross section of an electrolytic bath set at the upper part of the electrode is expanded toward the partition wall port side. CONSTITUTION:The upper part 4 on the cathode surface is downward graded toward the lower side of the partition wall port 5 between the graphite anode 1 inserted from outside and steel cathode 1. Consequently, the flow passage cross-sectional area of the graphite bipolar electrodes 3 arranged in the electrolytic cell is expanded. A DC voltage is then impressed on the cell, and Cl2 is generated from the anode 1 and the anode surfaces of the bipolar electrodes 3, and Mg is generated from the cathode 2 and the cathode surfaces of the electrodes 3. The Mg generated between the cathodes is taken into the electrolytic bath in the narrow gap between the electrodes by the ascending force of the gaseous Cl2, ascends and reaches the structural part 4 formed at the upper part of the electrode 3. Since the part 4 is extended to the lower end part of the partition wall port 5, the cross-sectional area of the flow passage is increased and a fin protruding from the upper surface of the electrolytic bath is provided to the electrode 3, the electrolytic bath flows stably from the rear wall to the partition wall 5 without being affected by the flow of the electrolytic bath at the upper part of the adjacent electrode.

Title: Input processor
Inventor: UMEDA HIROYUKI
IPC: H03H17/06
Filed: 1988-03-31
Abstract: PURPOSE:To prevent influences of noises to processed signals even if excessive noises are mixed by executing the filtration process to the currently inputted signals based on a noise probability outputted from a noise probability calculating section. CONSTITUTION:This input processor is provided with an A/D converting section 2, storing section 4, noise probability calculating section 3, and filter section 5. When a signal I is inputted, the signal I is compared with either one of the preceding input signal and output signal and a noise probability is calculated at the noise probability calculating section 3 and, at the same time, a filtration process is executed on the currently inputted signal I based on the calculated noise probability at the filter section 5. Therefore, no influence can be given to processed signals even if excessive noises are mixed.

Title: Level shift circuit
Inventor: TSUJIKAWA TOSHIAKI
IPC: H03K5/003
Filed: 1989-03-30
Abstract: PURPOSE:To attain the change in a DC level of a signal and to change the amplitude by shifting a level of an inputted signal in terms of DC, and attenuating the signal in terms of AC. CONSTITUTION:A resistor R2 (its resistance is R2) connects to a common connecting point between a resistor R1 and a constant current source 2 and the other terminal of the resistor R2 connects to ground in terms of AC. As a result, the level is shifted in terms of DC by R1XI1 and the signal is attenuated in terms of AC by R2/(R1+R2) and the result appears at an output terminal 3. Since the circuit acts like an AC attenuation circuit in addition to the DC level shift, when the circuit is employed for an inter-stage circuit among circuits connected in multi-stage, the difference from input and output DC levels, amplitude and dynamic range is arranged.

Title: Inspection of artificial barrier junction
Inventor: HIDAKA MUTSUO
IPC: H01L39/24
Filed: 1989-03-28
Abstract: PURPOSE:To surely evaluate the covering property of an overlay metal to a lower electrode with ease by a method wherein the overlay metal is formed in film, a reactive ion etching is executed using fluorine gas under a required condition, and it is examined whether the lower electrode of niobium is etched or not. CONSTITUTION:When a specimen or an overlay metal 13 formed in film on a lower electrode 12 of niobium is subjected to a reactive ion etching using fluorine gas, the region of the Nb 12 covered with the overlay metal 13 is not etched as the overlay is hardly etched by fluorine gas. On the other hand, the region of the Nb 12, where the overlay metal 13 is not well deposited and Nb is exposed, is etched by fluorine gas. In result, there occurs a much difference in level between a part covered with an overlay metal and the rest not covered, so that the coating failure of the overlay metal can be easily detected.

Title: Cooling method of rolled wire
Inventor: ISHIGAMI OSAMU
IPC: B21B1/18
Filed: 1985-04-11
Abstract: PURPOSE:To improve the cold workability of a wire by subjecting a hot rolled wire to gradient cooling in a cooling zone. CONSTITUTION:The temp. of the wire rolled at a high temp. is controlled to a prescribed temp. via automatic control for a cooling water flow rate prior to coiling with a coiler. The wire is subjected to the gradient cooling by increasing gradually the cooling water flow rate in the beginning of coiling in the cooling zone of the wire. The gradient cooling is executed in such a manner that the water cooling temp. of the wire inclines along the straight line 1 and therefore the temp. at the beginning T and end B of coiling of the wire is maintained approximately constant when the wire is charged into a slow cooler. The tensile strength in each part prior to the drawing of the wire is maintained constant by the above-mentioned method. The cold workability in the drawing stage is thus improved.
