Title: Method for observing electromagnetic field related to premonitory symptoms of an earthquake and device therefor
Inventor: FUJINAWA YUKIO
IPC: G01V3/12
Filed: 1995-10-12
Abstract: PROBLEM TO BE SOLVED: To transmits low frequency earthquake electromagnetic field signals, local characteristic value signals and improved local characteristic value signals of a plurality of observing stations to a base station, determine delay time, half-value width and main characteristic value signal of an electromagnetic field signal from the correlation function of each station, and estimate the generating time, place and magnitude of an earthquake from them with high precision. SOLUTION: In a plurality of observing stations, the electromagnetic field signal accompanying a minute breakage of earth crust is observed by a sensor 1 and made into an earthquake electromagnetic signal free from noise by a local discriminating part 3, and local characteristic value and improved local characteristic value are formed by a local characteristic value calculating part 4. A transmitting part 5 transmits them to the receiving part 6 of a base station, a correlation processing part 7 finds the delay time and half-value width from the correlation function between the data of each observing station, and a tomographic part 8 finds the spatial distribution and extension of an earthquake electromagnetic field signal generating source.  A main station discriminating part 9 extracts the electromagnetic field signal within an arrival allowable time width from the delay time, and a main station characteristic value calculating part 10 finds the main station characteristic value. A three-factor estimating part 11 synthetically estimates the earthquake generating time, generating place, and magnitude from them.

Title: Sliding material, piston ring, and manufacture of sliding material
Inventor: HASEI SEIJI
IPC: C23C14/06
Filed: 1992-10-02
Abstract: PURPOSE: To provide a sliding material or a piston ring of an excellent sliding characteristic in a Ti-N-O film by increasing oxygen atom % ratio discontinuously or continuously from the surface of a base body toward the surface of the film. CONSTITUTION: Titanium makes a stable hard substance together with nitrogen and oxygen. In particular, nitrogen remarkably heightens the hardness of titanium. Nitrogen content is desirable to be decided so that the Vickers hardness is not under 1000, because the hardness of the film is lowered even when the quantity is too small or too large. Further when the hardness of the film exceeds Vickers hardness 2000, abrasion of a mating material increases, and hence the oxygen addition quantity is desirable to be controlled so that the hardness becomes under this hardness. The above-stated ratio of titanium, nitrogen, and oxygen is desirable in the range of atom % ratio Ti:N:O=1:0.9-0.3:0.3-1.0.

Title: Picture profile emphasizing equipment
Inventor: TAKAYA KAZUYASU
IPC: G06T5/20
Filed: 1985-12-23
Abstract: PURPOSE:To eliminate the effect of a noise component onto an output picture by discriminating whether or not a noise component is included based on an output of a digital differential filter and inactivating the filter when the noise component is included. CONSTITUTION:An absolute value circuit 31 of a noise discrimination circuit 30 takes an absolute value of a Laplacian filter output from an adder 22 and converts it into simple amplitude information, the value and a reference value are compared by a comparator 32 and stored in a latch 33. The output of the latch 33 is outputted as profile information before one picture element. The output of the latch 3 and the output of the comparator 32 are ANDed by a NAND gate 34. The gate 34 gives an L level when the replay output is due to gray-white noise and gives an H level when the output is due to the normal profile. The output of the adder 22 or a 0 level output is selected depending on the output level of the gate 34 while the output of the discrimination section 30 is inputted to a NUX 41. Thus, the emphasizing processing is applied to the normal picture profile and no emphasizing processing is applied to a white- gray noise picture element.
