Title: Method for driving stepper motor
Inventor: AIZAWA ETSUKO
IPC: H02P8/00
Filed: 1990-06-01
Abstract: PURPOSE:To make a driving sound into a pleasant sound, by producing pulses at intervals corresponding to the reciprocal of musical tone frequency, and by making the driving sound itself of the motor into a melody. CONSTITUTION:By setting a manuscript on a paper feeding tray 14, a sensor 14 for sensing the setting of the manuscript is operated, and by the rotation of a motor 7, the manuscript is sent with paper feeding rollers 8, 9 until it reaches paper sending rollers 10, 11. In the case of this paper feeding operation, the motor 7 is driven by pulses at intervals corresponding to the reciprocal of musical tone frequency. Therefore, its driving sound comes into a melody. Then, pressing a transmission button, by the rotation of the motor 7, the manuscript is sent with the paper sending rollers 10, 11, and its carriage is stopped when its rear end reaches a sensor 13 for drawing out a paper. In the case of this carrying operation, since the motor 7 is driven by feeding the pulses of their equal time interval being 1/(the frequency of a musical scale) to it, its driving sound comes into the melody too.

Title: One shot multivibrator of variable pulse wodth
Inventor: IHARA KEIZOU
IPC: G11B20/06
Filed: 1980-10-09
Abstract: PURPOSE:To achieve excellent FM demodulation, by corresponding the change in pulse width based on the change in a counter output selected at a counter output selection signal generating circuit, into the change in the count number, in an FM demodulation of a magnetic recording/reproducing device. CONSTITUTION:A delay time of conversion from high to low level of the output of an FF10 in response to clock pulses is almost the same as the delay time when the output of the FF10 is converted into low to high level at the next clock pulse. Thus, the ratio of the output pulse width TOUT1 of the FF10 in response to n1-count  to the output pulse width TOUT2 of the FF10 in response to n2-count is n1/n2. Then, the DC level of an analog signal can be kept almost constant even if the reproduction speed is changed.

Title: Parallel data processors
Inventor: KAWAGUCHI HIROSHI
IPC: G06F15/163
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To process continuously inputted data in real time while using irreducibly minimum processor units(PU). SOLUTION: Data continuously inputted from a data input part 2 are distributed and processed by PU 4a-4c and in this case, however, the priority is set to the PU 4a-4c in the supply order of data. The PU 4a-4c request the transfer of their processing results to buffer memories 6a and 6b but when the requests of PU more than two are overlapped, a PU output control part 5 permits the transfer of the processing result in order from the highest priority. While one of buffer memories 6a and 6b writes the processing results from the PU 4a-4c, a BM output control part 7 reads the stored processing result from the other buffer memory and transfers it to a processing result storage part 8. Besides, a control CPU 1 can reset the priority of PG 4a-4c so as to speedily finish data processing as well.

Abstract: PURPOSE:To prevent a read line from being overlapped even if a scanner is carelessly separated by measuring the time required for continuously abutting the scanner upon a precedently read line, outputting an overlapped output when the measured time is short and intending the overlapped output in case of long measuring time. CONSTITUTION:When the scanner is continuously abutted upon the same line and the previously fixed prescribed time Tc has passed, a signal TUP is outputted from a line existence establishing means 22 and sets up the output Q of a SR flip flop (FF) 26 through an AND gate 25. When the output of the FF 26 becomes true, the output is transmitted to an output control part 19 through an OR gate 23 and the output control part 19 outputs (ROUT) its input (RLINE). On the other hand, an original replacement detecting means 20 detects the replacement of an original, and hen the original is replaced, erases the contents stored in a recognizing line storing means 17 and resets the FF 26. Even if the scanner is carelessly separated after reading out respective lines of the original, the already read lines are not overlapped.
