Filed: 1989-09-06
Abstract: PURPOSE: To prevent arcing by connecting an insulation anode supply conductor for connecting a clip to a wire wherein the clip is tightened inside a cap, to a standard type anode button disposed on a glass outer envelope wall of a cathode-ray tube. CONSTITUTION: An anode connector assembly C is attached on a proper part of a cathode-ray tube A, a skirt part 64 of a flexible cap 32 is pushed to an envelope 10, and a connector clip member 34 is coupled with a anode button B.

Title: Probe for scanning probe microscope, its manufacture, recording and reproducing apparatus and fine working apparatus using the probe
Inventor: TODA TAKAO
IPC: G01N37/00
Filed: 1993-09-17
Abstract: PURPOSE:To obtain a mechanically and electrically stable probe by a method wherein a cantilever which is composed of a dielectric thin film covered with a conductive thin film and a conductive needle crystal which is boned to its tip by a low-melting-point metal are provided. CONSTITUTION:A probe is constituted in such a way that a conductive needle crystal 5 is bonded, by a low-melting-point metal 4, to the tip of a cantilever 160 which is composed of a dielectric thin film 2 covered with a conductive thin film 3. It is not required that the probe as a whole is covered with a metal thin film thanks to the conductivity of the low-melting-point metal 4 as an adhesive. As a result, the curvature of the tip part of the probe does not become large. In addition, since the needle crystal 5 and the cantilever 160 are connected electrically via the low-melting-point metal 4 as the adhesive, their electrical connection is made stable. In addition, thanks to the mechanical strength of the low-melting-point metal 4 as the adhesive, the needle crystal 5 is not detached from the cantilever 160.

Title: Circuit apparatus for determining power of cyclic signal
Inventor: UERUNAA RUSHIYUNITSUHI
IPC: G01R19/165
Filed: 1988-09-14
Abstract: PURPOSE: To estimate whether a signal whose band is limited has a larger power than a specific value or not by counting one number of both logic values of the output of an absolute voltage value-comparator. CONSTITUTION: An absolute voltage value-comparator 12 checks to see if the absolute voltage value of an input signal is larger or smaller than a threshold where the absolute voltage value of an input signal is predetermined and supplies a pulsive output signal. A sampling circuit 14 samples the output signal of the comparator 12 and supplies a digital signal to a counter 16. Then, the counter 16 checks to see if how many sample values among the output signals of the sampling circuit 14 have high or low logic values within a predetermined period. The result gives one piece of statistical information regarding the amplitude of the periodical input signal with the voltage of a voltage source as a reference via the uppermost bit of the counter 16, thus estimating a signal power.

Title: Activation method of nickel-metal hydride battery
Inventor: OGURA HIROSHI
IPC: H01M4/38
Filed: 1998-08-19
Abstract: PROBLEM TO BE SOLVED: To effectively prevent leakage of an electrolyte to the outside of a system and thereby perform an activation process with a stable operation, by connecting an electrolyte reservoir container filled with an alkaline electrolyte to a battery lid and performing charge and discharge under the communication of the electrolyte in the battery with the electrolyte in the container when the battery containing the alkaline electrolyte is activated. SOLUTION: Before performing charge and discharge, an upper opening part (a part to which a safety valve is mounted after activation) of a battery lid is filled with an electrolyte, an electrolyte reservoir container of which upper part can be opened is connected to it, a condition that the electrolyte in the container sufficiently communicates with the electrolyte in a battery cell is confirmed, and thereafter, the charge and discharge are performed. For the method for connecting the electrolyte reservoir container to the battery lid, a method to connect the container to the battery lid with a screw-in type is more desirable than a method using an insertion type from a view point of prevention of electrolyte leakage in charging and discharging, and thereby, the container functions as a head tank and easily feeds the electrolyte into the battery cell.
