Title: Discriminating method for variation factor of reproducing output of magnetic recording and reproducing device
Inventor: YASUE HIDETAKA
IPC: G11B5/02
Filed: 1985-05-15
Abstract: PURPOSE:To decide factors of output variation of a reproducing signal accurately and easily by measuring the quantity of variation in the output spectrum of an equalizing circuit with time at least two frequencies as to the reproducing signal which is corrected by the equalizing circuit. CONSTITUTION:The reproducing signal from a recording medium where a signal is recorded with white noise is corrected by the equalizing circuit so that spectra S0 corresponding to >=2 optional frequencies f1 and f2 are uniform almost at the frequencies. Then, the quantity of variation in output spectrum with time at the frequencies f1 and f2 of the equalizing circuit is measured by, for example, a spectrum analyzer. Consequently, when the spectrum variation corresponding to the frequency f2 is larger than that corresponding to the frequency f1, it is decided that the output variation of the reproducing signal is caused by variation in spacing. When both quantity of spectrum variation are nearly equal, on the other hand, it is decided that the output variation of the reproducing signal is caused by tracking variation. Thus, the factors of the output variation of the reproducing signal are discriminated accurately and easily.

Title: Printing system, printer, printing data generator and printing method
Inventor: KURATA KENICHI
IPC: B41J5/30
Filed: 1998-04-15
Abstract: PROBLEM TO BE SOLVED: To complete copy printing by optimally transmitting printing data by confirming an amount of mounted memory at a printer side when the copy printing is executed. SOLUTION: When the copy printing is executed, the printing data are arranged between a copy start command and a copy end command and transmitted to a printer 10 by a printer driver 2. A judging part 34 of a copy control part 32 judges whether all pieces of the printing data are stored in a copy buffer 44 or not and informs a judgment result to a command issuing part 4 of the printer driver 2. When all pieces of the printing data are stored, it is the case that the copy printing is executed by one time of data transmission, therefore, a processing at the side of the printer driver 2 is completed. When the printing data are not stored due to shortage of the amount of the mounted memory, the printing data are repeatedly transmitted by a number according to the number to be printed. Consequently, the copy printing is executed irrespective of size of memory amount of the copy buffer 44.

Filed: 1991-05-10
Abstract: PURPOSE:To simply and precisely make possible the detection of zero phase voltage by forming an electrode capable of receiving electric fields of polyphase electric conductors at an arbitrary position thereabout and detecting the electric field generated on the outside surface thereof. CONSTITUTION:A cylindrical electrode 3 is provided around three-phase high voltage distribution lines 1 and an electric field sensor 4A, a signal processing part 5, an input optical fiber 7 and an output optical fiber 8 are set so as to become vertical to the electric field E of the electrode 3. By the constitution, electric charges generated at the outside of the electrode 3 formed at an arbitrary position around the distribution lines 1 are proportional to the whole electric charges in the cylindrical electrode 3 in accordance with the Gauss' theorem and thereby they are proportioned to zero phase voltage. Accordingly, the electric field generated at the outside of the electrode 3 is proportional to the zero voltage whose the distribution lines 1 can be detected by the use of a sensor 4A. Since the electric field observed with the use of the sensor 4A does not include an unnecessary positive phase and an opposite phase and even an error in accordance with the interaciton of the three phase distribution lines 1 is negated, the data having a small error can be obtained.
