Title: Recording speed discriminating device
Inventor: KAWAGUCHI SHINTARO
IPC: G11B15/467
Filed: 1987-03-28
Abstract: PURPOSE:To discriminate driving speed at the time of recording, by comparing the frequency ratio of the motor rotating speed of a recording medium and the reproducing output of a control signal, storing a result in a time series way, and detecting the coincidence with past results successively. CONSTITUTION:By frequency-dividing the reproducing output SCP of a control pulse to 1/n and supplying it to a sequence generation circuit 12, signals are generated in sequence of S5, S1...S4, and S5... setting a frequency-dividing signal as reference, and a driving motor frequency signal SG is supplied to an m-bit counter 14 via a processing circuit 13 in the period of the S5-S1, and a value corresponding to the frequency ratio of the SCP and the SG is counted. Counter information D1 is compared with reference information D2 and D3 at comparators 15 and 16, and outputs S11 and S12 are set at an (H) or an (L), and they are inputted to a successive coincidence circuit 17, and also, are latched by one-bit latch circuits 18 and 19 by the signal S3. The circuit 17 detects the coincidence of a latch output with the next signals S11 and S12, and outputs discriminated results as an S13 and an S14. The counter 14 is cleared by the signal S4. By constituting the device in such way, discrimination can be accelerated, and also, erroneous discrimination can be decreased.

Abstract: PROBLEM TO BE SOLVED: To decrease the frequency of key operations for switching an input mode. SOLUTION: When a processing is started, it is judged in a step (1) whether or not a key input device is operated and when not (NO), this step (1) is repeated. When the operation of the key input device is judged in the step (1) (YES), it is decided in a step (2) whether a tone input key is operated. When the tone input key is operated in the step (2) (YES), the input mode is switched 'number' in a step (5). Further, it is judged in a step (6) whether or not one of '0' to '4' or '-' indicating a tone is inputted and when there is no input ('NO', the step (6) is repeated. When one of '0' to '4', and '-' is inputted in the step (6), the input is saved in the step (7); and the input mode is switched to 'English' and a return to the step '1' is made.

Filed: 1989-03-28
Abstract: PURPOSE:To make the analysis easier by forming a conductive membrane on the surface of an insulator to be a sample while leaving a specific width of exposing area, and detecting the secondary ion generated from the exposed area by a position sensitive detector. CONSTITUTION:On the surface of a sample 1 of an insulator, a conductive membrane 2 of a metal or the like is spread by a spattering or the like, and after that, a window with the width less than 100mum is formed on the conductive membrane 2 by an etching or the like to expose the surface of the sample at the window 3. When the primary ion beams 5 are radiated to the window 3, the secondary ion beams 6 generated thereby are detected through a secondary ion optical mass analyzing system 7 and a position sensitive detector 9. In this case, since the potential variation amount of the window 3 is almost proportional to the width of the window when it is less than 100mum, the reduction of the secondary ion intensity can be compensated easily, and the analysis can be carried out easily without using an auxiliary device such as an electron beam radiating device.

Abstract: PURPOSE:To obtain a roll having excellent heat resistance, wear resistance and heat fatigue cracking resistance by covering a roll body surface by a composite padding layer, mixing metal with ceramic grain and forming groove stripes as a grid state on the padding layer. CONSTITUTION:The composite padding layer 2, which protects by covering the surface of the roll body 1, has composite structure, mixing the metal with the ceramic grains, and by this composite effect, the roll has the high temp. wear resistance and the heat resistance.

Further, as the groove stripes B are formed, the heat stress generated in the composite padding layer 2 at the time of using is dispersed are relaxed by the groove stripe B. By the effect, multiplicating the effect of the heat stress dispersion and relaxation by the groove B and the effect of the groove stripe A, the heat fatigue cracking resistance of the roll surface layer is further strengthened.

Abstract: PURPOSE:To obtain sufficient S/N even with mass-produced magneto-optical heads having a phase difference by selecting the refractive indexes and film thicknesses of respective layers in such a manner that the Kerr rotating angle, Kerr ellipticity and reflectivity of Kerr effect reproduced light and the phase difference generated in the magneto-optical disk have specific relations. CONSTITUTION:A 1st protective layer 2, a recording layer 4, a 2nd protective layer 3, and a reflecting layer 5 are disposed in this order on a transparent substrate 1. The refractive indexes and film thicknesses of the respective layers are so selected that Q attains >=0.5 and delta attains <=1 deg. in equations I, II where the Kerr rotating angle of the Kerr effect reproduced light is designated as theta, the Kerr ellipticity as epsilon, the reflectivity as R, and the phase difference generated in the magneto-optical disk as delta. Namely, the refractive indexes and film thicknesses of the respective layers are optimized by taking the protective characteristics and heat transmission characteristics into consideration so as to obtain the largest possible Kerr rotating angle theta and the small Kerr ellipticity epsilon. The sufficiently high S/N at which about + or -15 deg. fluctuations in the internal phase difference are of no problems in practicable use is secured even if the magneto-optical head of a mass production type have the above-mentioned fluctuations.
