Title: Coding system
Inventor: KAWARABAYASHI SHIGEYUKI
IPC: G11B5/09
Filed: 1979-07-17
Abstract: PURPOSE: To prevent the increase in DC component, by controlling the consecutive 0 or 1, through the specified maximum inversion interval, by controlling the coding in response to the number of accumulation of 2-bit binary signal 11,00 coded.  
     CONSTITUTION: The binary signal 0,1 in bit period T input from the terminal 8 is converted into the binary bit 00 or 01 for the signal 0 and 01 or 10 for the signal 1 depending on the bit coded immediately before, by means of the MFM code converter 20, and output from the OR gate 17 via the 4-bit buffer circuit 21. The output of the addition and subtraction circuits 26,27 is made to high level according to the difference of accumulated number of the binary bit 11,00, and the code conversion is controlled with the output of the memory circuits 24,25 storing the 4-bit 1..., 0... . Thus, the maximum inversion interval of the converted code is controlled to 2.5T to be the conversion code suppressed for the consecutive 0 or 1, allowing to increase the DC component. As a result, the conversion code for control in which malfunction is hardly taken place can be obtained.

Title: Text coding
Inventor: SUTEIIBUN JIEIBESUPARUKO
IPC: G06F40/189
Filed: 1990-04-05
Abstract: PURPOSE: To efficiently insert and delete characters by adding a new peculiar token to advance the control to the next atom in the case that a present atom in a string is not equal to any preceding atoms encountered before. CONSTITUTION: A text processing function is advanced by using successive tokens to access a present token attribute. A line feed algorithm uses successive tokens to access measurement information in token attributes. Normally, a present line is terminated by the preceding token in the case of excess over the line width; however, if the text is right justified, spaces between words can be extended. If the line cannot be sufficiently extended finally, a token corresponding to a word making spaces too narrow is checked, and it is discriminated whether it can be hyphenated or not. Thus, line feed is efficiently performed, and other editing functions are executed at a higher speed.

Filed: 1990-04-05
Abstract: PURPOSE:To output a pulse even when a drive input signal level is close to zero by driving a load according to a differential component between the two phases of pulse-shaped outputs to be outputted from the first and second output means. CONSTITUTION:A load 14 connected between the outputs of first and second output means 12 and 13 is driven by the two phases of pulsative output signals to be outputted from these first and second output means 12 and 13. Then, the width of the output pulses from the first and second output means 12 and 13 is successively controlled by applying a drive timing command B1 corresponding to a drive input signal A, which is inputted to a drive timing generating means 11, from the driving timing generating means 11 to the first and second output means 12 and 13. Thus, the problem of not outputting the pulse when the drive input signal level is close to zero can be prevented.

Abstract: PURPOSE:To obtain metallic powder having a large specific surface area and high coersive force and being superior in anti-corrosiveness by forming compound layer of Si or the like on the surface of needle goethite, reducing and dehydrating thus formed chemical compound to obtain magnetite, and then forming and reducing non-ferrous transition metal compound layer on the obtained magnetite. CONSTITUTION:Forming Si and/or Al compound layer onto the surface of needle goethite is realized by precipitating insoluble matter from the chemical compound solution, depositing colloidal compound, and so on. After that, the resultant matter is reduced and hydrated to obtain magnesite. On the surface of this magnesite, non-ferrous transition metallic compound layer is formed and then Al compound layer is formed onto the nonferrous transition metallic compound layer. The non-ferrous transition metal used in this invention is represented with Cr, Mn, Co, Ni, etc. Further, the Al compound is formed by adding alkali water solution to the magnetite slurry and further adding water solution of aluminum sulfate, or the like so as not to lower pH of the system by means of precipitation. The magnetite having the non-ferrous transition metallic compound layer and Al compound layer thus obtained can be reduced as it is.

IPC: H04N5/57
Filed: 1986-04-23
Abstract: PURPOSE:To easily obtain the optimum brightness on the screen of a display by detecting the peripheral brightness of the display and displaying an image indicating the peripheral brightness on the display screen. CONSTITUTION:An illuminace sensor 1 detects the peripheral brightness of a display 10 and sends the detecting signal to an image signal generating part 3 to form a sending image signal (d). On the other hand, a time control part 5 to which a control signal (e) is applied from an operation part 4 outputs a time signal (f). Consequently, the image signal (d) is applied from a display control part 6 to a luminance control part 7 as an image signal (g) only in the period of the time signal (f). The control part 7 mixes the main image signal (a) with the image signal (g) and supplies the mixed signal to a CRT 8, so that an image 12 indicating the peripheral brightness is displayed on the prescribed position of the display screen 11. The display of the image 12 makes it possible to detect the peripheral brightness and to easily obtain the optimum brightness on the screen of the display.

Abstract: PURPOSE: To synchronously control each step guide vane of a reversible pump- turbine, by controlling the switch motion of a guide vane in the way introducing a revolving speed signal sent from a speed detecton device connected to hydraulic machinery into a speed governor.  
     CONSTITUTION: When a power system load 16 is increased, a revolving speed 14  of a generator motor comes lower than a target value 71 and this upper-step revolving speed deviation signal S 01  makes a primary distributing valve 75 go upward. With this motion, an upper-step auxiliary servomotor 76 operates toward 'OPEN'. In addition, a stroke signal S 02  of the servomotor 76 makes an upper- step servomotor 20 operate toward 'OPEN' in order to cause a secondary distributing valve 79 to go upward. Opening of an upper-step guide vane 8 is set by the servomotor 20. The stroke signal S 02  is transmitted to a cam 80 and makes a lower-step servomotor 40 operate toward 'OPEN'. This servomotor 40 is connected to a lower-step guide vane 9 and thereby relationships of an opening position between guide vanes 8 and 9 becomes equalized.
