Title: Laminated piezoelectric actuator
Inventor: KATOU TOMOYOSHI
IPC: H01L41/083
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To prevent part of inner electrodes from being poor conduction if part of outer electrodes is broken, by placing corrugated linear conductors parallel to the outer electrodes and fixing the conductors to both ends of the electrode electrodes in their laminating direction and their contact parts with these electrodes. SOLUTION: Corrugated linear conductors 5 are placed to contact with outer electrodes, 3, except the crests 8a and troughs 8b of their corrugations arranged in the laminating direction X of a laminated actuator while their height is winder than the width A of the electrodes 3 and the contacted parts are fixed through solder 6 to the electrodes 3, together with their both ends 9. Since the crests 8a and troughs 8b of the corrugations of the conductors 5 are not contacted with the electrodes 3, they are linear, obliquely passing through the electrodes 3. As the result the displacement exerted on the linear part of the conductor 5 contacted with the electrodes 3 per unit length is a little to result in a low load on the conductor 5. Since the crests 8a and troughs 8b of the conductors 5 are not fixed to the electrodes 3, they is subjected to no stress due to the displacement.

Title: Method for measuring stress of steel material from vibration characteristics by compulsory vibration impressed thereto
Inventor: OTSUKA KOJI
IPC: G01L1/00
Filed: 1990-04-19
Abstract: PURPOSE:To easily measure the stress of a steel material in an actual structure on the spot by forcing the steel material to vibrate, and measuring/analyzing the vibration characteristics of the steel material. CONSTITUTION:A steel material 2 in a circular rod (iron reinforcing rod) having the diameter 16mm is set at the upper and lower chucks of a tensile strength tester 1. An accelerometer 3 is fixed to the steel material 2 in order to measure the vibration. The steel material 2 is forced to vibrate by a small hammer at each stage as the load of the tester 1 is increased every 1 ton from zero. The vibration of the steel material 2 is measured by the accelerometer 3 and amplifier by a dynamic distortion measuring apparatus and further analyzed by a waveform analyzer. The output is recorded by a printer. The recording result is compared with samples of, e.g., the distance of the steel material 2 between the chucks, material, diameter and the like of the steel material 2, whereby the load of the steel material 2 is obtained from the measured specific frequency.

Title: Method for examining approximate amount of nitrogen oxide contained in environment
Inventor: NAKAJIMA HIDEKAZU
IPC: G01N23/223
Filed: 1993-04-30
Abstract: PURPOSE:To easily monitor the approximate amount of nitrogen oxide contained in atmosphere at any location by placing a brass test piece where a constant inner stress is applied within a measurement environment atmosphere and then determining and analyzing the nitrogen oxide adhering to the brass surface after a specific period passes. CONSTITUTION:Brass which is desirable for adsorbing NOx consists of that containing 20-50wt.% zinc or that further containing 8-12wt.% nickel and has an inner stress which is equal to or more than 100MPa. When Zn of the brass is equal to or less than 20%, stress sensitivity is reduced. When it is equal to or more than 50%. the brass becomes brittle. Also, by rolling a brass piece with 85%, or more machining rate, preferably 90-95%, machining rate, approximately 100MPa inner stress is generated. The brass with the inner stress 100MPa or more indicates an improved NOx adsorption property, thus resulting in corrosive crack. The adsorbed NOx is determined for a physically and chemically adsorbed substance and the amount of adsorption is proportional to NOx concentration and time, thus measuring the NOx concentration easily.
