Title: Echo detector employing simulated noise system
Inventor: TOKURA NOBUYUKI
IPC: G01R31/08
Filed: 1981-09-28
Abstract: PURPOSE:To remove noise components in the measurement by allowing the output of a correlation detecting means to be zero theoretically when the reflection is zero at a measuring point in the computation of a correlation based on reflection signals of a simulated noise system received after it is transmitted to an object to be measured. CONSTITUTION:A simulated noise generator 13 generates a simulated noise system containing 0 and 1 at random. When this system is delayed by a timer to obtain a self-correlation, the correlation is 1 at an interval of Mt with the cycle set at M and otherwise 1/2. So, a simulated noise system exclusive ORed with a  clock with a cycle of 2t is given a delayed time D with a variable delay circuit  17 and inverted with an exclusive OR circuit 18 at an interval of 1/f0. The output of the circuit 18 is inputted into a switch 16 with an output b and taken out alternately therewith. When those thus obtained are transmitted to an object to be measured, a variation in the correlation of (M 1)/2M develops at a point + or -(D+t/2) at an interval equal to odd multiplication of Mt and, at the points other than the above, the output becomes zero thereby improving the signal noise ratio.

Title: Method and device for detecting leakage acoustically
Inventor: YAMADA IZUMI
IPC: G01M3/24
Filed: 1991-06-25
Abstract: PURPOSE:To enable accurate detection of leakage by capturing changes in the acoustic characteristics of a sound propagating medium due to leakage, and determining whether or not there is leakage. CONSTITUTION:Water introduced into a steam generator 1 from feed water inlet piping 2 is allowed to pass through a coiled heat transfer pipe 3 and is heated by high-temperature sodium (Na) fed from inlet piping 6 and is converted into steam and taken to the outside from steam outlet piping 4. Sounds applied to the container 7 of the steam generator 1 by echo sounders 9a-9c pass through the wall face of the container 7 and the inside Na and are detected by sound detectors 11a-11c. Detected sound signals are detected by synchronous wave detectors 13a-13c and a leakage judging unit 14 determines according to wave detection signals whether or not there is leakage. If the water leaks into the Na from some part of the heat trasfer pipe 3, hydrogen bubbles are generated through the reaction of the Na with the water and mixed in the Na. The speed of sound is lowered in the mixture of Na and steam as compared with in pure Na and sound attenuation is increased. Thereby the occurence of leakage is judged by the leakage judging unit 14.

Title: Method for gravure printing
Inventor: CHIBA HIROSHI
IPC: B41C1/04
Filed: 1989-06-16
Abstract: PURPOSE:To avoid a shift in registering by adjusting the register when a printing plate formed by machine engraving and a printing plate formed by etching are printed in mixture by use of the position of pin holes of a film original plate. CONSTITUTION:In the general transfer, the starting position of the transfer shifts between the first time and the second time depending on whether a carbon tissue is present. In order to remove the difference between a plate formed by etching and a plate formed by machine engraving, a distance 7 from a pin hole of a film original plate to a pattern is adjusted. Taking the film original plate for machine engraving as a reference, the position of a pin hole on the surface of a film original plate for etching for the second transfer is separated from the pattern so that the distance 7 is within 0.2-0.5mm in addition to the reference. This value is dependent on the thickness of the carbon tissue transferred at the first time. If the film original plate for etching is taken as a reference, the position of a pin hole on the surface of the film original plate for machine engraving for the second transfer is brought closer to the pattern so that the distance 7 is within 0.2-0.5mm.

Title: Variable capacitance element
Inventor: KOUNO MOTOHIRO
IPC: H01L29/94
Filed: 1983-08-23
Abstract: PURPOSE:To increase the ratio of capacitance change by constructing an insulating film in a laminated structure of the first insulating film formed on the surface of a semiconductor substrate and the second insulating film formed on the first film. CONSTITUTION:An insulating film 25 for forming a capacity read-out unit 24 is constructed in a laminated structure of the first insulating film 25A formed on the surface of an N type semiconductor region 11 such as an oxidized film (SiO2) and the second insulating film 25B formed on the first film such as a nitrided film (SiN). Thus, when the film 25 of the unit 24 is constructed in a laminated structure, the deterioration of insulation due to small thickness of the film 25A is supplemented by the upper film 25B even if the thickness of the film 25A is formed to be small, and H/L ratio can be increased without deteriorating the insulating property. Particularly, the nitrided film has excellent insulation and excellent masking property against an invasion of organic and inorganic impurities from the exterior. Accordingly, even if the thickness is small, sufficiently large H/L ratio can be obtained even if combined with the oxidized film.
