Patent JP-H01317283-A (JP)
Title: Head positioning control system and disk device applying same
Inventor: YANO YOSHIHIKO
IPC: G11B21/02
Filed: 1988-06-16
Abstract: PURPOSE:To shorten the overall processing time by varying the positioning process cycle based on the servo information. CONSTITUTION:When a microprocessor 14 performs the positioning and following processes with high accuracy to a desired track of a head 3, a sector pulse N detours a counter circuit 28 and enters directly an input port P2 of the processor 14. Then the head 3 is positioned by the interruption processing every time the servo information Ic prepared are each boundary of sectors passes through the head 3. In case the high positioning accuracy is not required, the processor 14 inputs the pulse N to the port P2 via the circuit 28. Thus the pulse N is inputted to the processor 14 every (n) times (n: >=2). As a result, the redundant positioning process frequency due to the interruptions can be reduced and the overall processing time is shortened.

Abstract: PURPOSE: To crystallize an α-anomer into a pure form and to separate the compd. of the title by bringing an anomer mixture into contact with a solvent, heating, adding a counter solvent and decreasing the temp.  
     CONSTITUTION: An anomer mixture of formula I and formula II (X is a hydroxy- protecting group; R is a (substd.) alkyl) is brought into contact with a solvent such as dichloromethane and propyl acetate and heated at 30 to 50°C. After heating, a counter solvent such as ethanol, modified ethanol and isopropylalcohol is added to the mixture, and the temp. is decreased to 23 to -10°C (preferably 23 to 5°C) to crystallize 2-deoxy-2,2-difluoro-D-ribofranosyl-3,5-0-benzoyl-1-α- methansulfonate.

Title: Character processor
Inventor: MAEDA KENJI
IPC: G06F17/22
Filed: 1985-07-09
Abstract: PURPOSE:To simplify a process by providing a means that measures the time interval and a recognizing means that performs a recognition process for different KANA (Japanese syllabary) corresponding to a measured time interval. CONSTITUTION:A CPU 2 starts up a timer 3 and makes the timer start the measuring operation of the time interval between the characters and when a key input is not obtained for even after the lapse of a specified time t1 after the timer is started up, the KANA conversion for the character inputted before the start up of the timer is performed. When a consonant is inputted after the character, a regular KANA conversion is performed. On the other hand, when the operation of a vowel is discriminated, the value of the timer is read, and whether the time interval between the inputting time of the character and that of the vowel exceeds a prescribed time t2 or not is discriminated. And when it is an affirmative judge, the KANA conversion is performed as the combination of the character with the vowel, and when it is a denial judge, the process is completed by performing the KANA conversion dealing the character as a regular one. Thereby, a complicated process is eliminated and a character processor can be realized in which the character recognition is exactly performed and operability is superior.

Abstract: PURPOSE: To dampen a vibration of a band by mounting a pair of previously compressed energy absorption grommets to a half of a clamp comprising two portions and absorbing a vibration energy of a metal-driven band used for a positioning by moving a driven element at a motion system of a servo control. CONSTITUTION: A grommet 52 attached to a band clamp 32 and a grommet 54 attached to a keel clamp 30 are the same vibration-dampening grommet and act to mechanically isolate the band clamp 32 from the keel clamp 30 and isolate a driven element 18 from a band 12. The band 12 is tensioned in order to bring the grommets 52, 54 to the final compression value. The grommets 52, 54 are compressed by a force generated by pulling the band 12 and the keel clamp 30 is left from the band clamp 32. A space 56 is loosened to freely rotate on a tightening tool 44. The separation provides the maximum isolation to the two clamps.

IPC: H04N9/73
Filed: 1994-06-30
Abstract: PURPOSE:To provide the method for extending the variable range of color temperature kept by white balance neither increasing the number of bits in a control signal nor degrading the degree of convergence by making arbitrary one of three primary colors a reference color and keeping white balance while variably controlling the levels of signals in the other two colors. CONSTITUTION:Automatic white balancing is started and it is discriminated whether an R signal level is equal with a reference G signal level or not. When the discriminated result is NO, namely, the R signal level and the G signal level are not equal, the level relation of the R signal level and the G signal level, namely, whether the R signal level is higher than the G signal level or not is discriminated. When this discriminated result is YES, the gain of the R signal is decreased and further, it is discriminated whether the control signal of the R signal level is out of the variable range or not. In the case of YES, namely, when the control signal of the R signal level is out of the variable range, error is displayed and automatic balancing is finished. When the R signal level is not higher than the G signal level, the R gain is increased. When the result is out of the G variable range, error is displayed. Similar white balance control is performed for a B signal and well as when the B signal level gets equal with the G signal level, the control is finished.
