Title: Decoding device of two-cycle data signal
Inventor: KURARENSU HARISON
IPC: G06K7/00
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To accurately and efficiently decode a deteriorated double-cycle signal by providing the microprocessor of an intelligent digital filter. SOLUTION: When a data signal is read out by magnetic reading heads 9A, 9B, 9C, the sample of a double-cycle data signal is repeatedly obtained, and the sample is converted into a series of values expressing the value a digital signal (amplitude and polarity) therebetween. The double-cycle signal is sampled by a sufficiently high frequency so that the digital sample may accurately express the double-cycle signal. The microprocessor 17 of an intelligent digital filter processes the digital value to decode the double-cycle data signal. Therefore, a method and a device for accurately and efficiently decoding a deteriorated double-cycle signal by one-time reading operation can be obtained.

Title: Printing method of dot printer
Inventor: HAYASHI MIKIO
IPC: B41J2/485
Filed: 1993-12-10
Abstract: PURPOSE:To enable the speed-up of printing to be done without impairing print ing qualities by effecting print at higher speed than that of original dot pattern printing based on the secondary dot pattern produced by selecting the secondary dot data at intervals of (m) pieces in a continuation of 2n-pieces or above secon dary dot data. CONSTITUTION:Each of respective dot data is converted into four secondary dot data being in continuation of the line direction and, next, the secondary dot data developed on the place corresponding to a dot distance of 1.5 times to the smallest dot distance in the original dot pattern, i.e., only the secondary dot data at intervals of 5 pieces is selected, while omitting anything other than this. Although one-piece original dot data Is converted into the four-pieces secondary dot data at this time, It can be converted into the arbitrary (n)-pieces secondary dot data by setting the storing capacity of RAM 3. In this instance, when the 2n-pieces or above secondary dot data continue, the secondary dot data at intervals of (m) pieces is selected, and further, as the scanning velocity of a printing head is made K-times during the period of printing the original dot pattern, the velocity becomes K-times during the period of printing the original dot pattern.

Title: Adhesion strength measuring apparatus
Inventor: YANAGISAWA MASAHIRO
IPC: G01N19/04
Filed: 1989-11-29
Abstract: PURPOSE:To enable measurement of an adhesion strength of a thin film in various directions by giving a shape of a wedge to an indentor adapted to detect a cracking propagation state (AE characteristic) generated inside when a test piece is forced to deform to prevent a breakage thereof. CONSTITUTION:A side 13 and an edge face 14 of an wedge-shaped indentor 4 mounted at the tip of a piezo-electric actuator 5 are forced into a test piece 1 and forcing values thereof are measured. In other words, light 8 from a photonic sensor 9 is reflected to a mirror 6 carried on a sample tray 3 through an optical fiber 7 moving simultaneously with the indentor 4 and a change in intensity of the reflected light returning to the fiber 7 is converted to a change in voltage gain with the sensor 9 to measure a change in distance between the fiber 7 and the mirror 6. Then, an AE signal from the indentor 4 undergoes a data processing with an AE analyzer 10 to perform an analysis on a frequency distribution, an amplitude distribution and a counting and an AE signal attributed to a peeling between the thin film and a substrate is detected. In this manner, the indentor 4 employs a wedge-shaped AE converting element having a piezo-electric property to reduce breakage during a forcing thereby enabling measurement of adhesion strength of the thin film in various directions.
