Title: Motor driving apparatus
Inventor: SUZUKI HITOSHI
IPC: H02P1/42
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To realize a motor driving apparatus which can be soft-started to generate the rated number of rotations even if it is started again with a cycle shorter than the time required for soft-start. SOLUTION: Since a transistor Q2 turns on with a current bypassed to a bypass route 31 and an electrolytic capacitor C1 is charged with a base current of the transistor Q2, the soft-start time can be set longer even if an electrostatic capacitance of the electrolytic capacitor C1 is small. Moreover, since the electrolytic capacitor C1 is inhibited to discharge while the transistors Q3 turns off during the operation, the rated number of rotations can be generated by eliminating a bypass current. In addition, the capacitor is discharged when transistor Q3 turns on during the off condition. This discharge is conducted quickly because an electrostatic capacitance of electronic capacitor C1 is mall. Therefore, soft-start can be enabled in the next on condition.

Title: High permeability alloy
Inventor: WATANABE MIKIO
IPC: C22C38/08
Filed: 1987-03-02
Abstract: PURPOSE:To obtain a high permeability alloy excellent in wear resistance without deteriorating magnetic properties, by blending an Fe-Al-Si magnetic alloy and an Fe-Ni magnetic alloy in a specific ratio. CONSTITUTION:The high-permeability alloy has a composition consisting of, by weight, <=50%, preferably about 2.5-25%, of Fe-Al-Si magnetic alloy and the balance Fe-Ni magnetic alloy. This alloy has superior wear resistance and is suitably used as magnetic head material. As the above Fe-Al-Si magnetic alloy, e.g., the one principally composed of about 4-12% Si, about 3-8% Al, and the balance Fe and further containing, if necessary, Ni, C, Ti, Zr, Ta, Nb, Mo, W, Ru, etc., is used. On the other hand, as the Fe-Ni magnetic alloy, e.g., the one composed principally of about 35-90% Ni and about 5-55% Fe and containing, if necessary, Mo, Cu, Cr, Mn, etc., is used. The above- mentioned high permeability alloy can be obtained by mixing both magnetic- alloy powders mentioned above in an inert atmosphere, etc., and by subjecting the resulting powder mixture to compacting and sintering.

Title: Positioning device for electron gun
Inventor: SHIMIZU YUKIO
IPC: H01J9/00
Filed: 1978-04-21
Abstract: PURPOSE: To secure an correct positioning for the rotary component of the electron gun to the  fluorescent screen with no effect of the size of the electron gun or the shape of the through hole  by obtaining the coincident point for each electron gun between the positioning through hole  and the reference beam.  
     CONSTITUTION: Light source 13 and photoelectric conversion element 19 are distributed linearly  across electron gun 11 via positioning through hole 12 and 12. The electron gun is turned in a  fixed speed via driving unit 22 with the command given from control unit 24, and beam 14  begins to pass through hole 12 and 12 to pass through from point α where the current of element 19 begins to flow through point β of the maximum value where the beam is in agreement  with the axial line of hole 12 and 12. And the rotation of the electron gun is topped at the point  where beam 14 gets out of hole 12 and 12. The operation amount is measured by counter 24a  from point α to point γ right before stoppage, and 1/2 value measured in set as the preset value  of preset counter 24c. Thus, the electronic gun is turned reversely from driving mechanism 22  by the amount of the above preset value, and so the gun is stopped at point β where a coincidence is obtained between the axis of the beams which are coincided previously with the reference  direction of the fluorescent screen and hole 12 and 12. Thus, the positioning completes.

Title: Image processing unit
Inventor: TOYAMA KATSUHISA
IPC: H04N1/60
Filed: 1995-03-07
Abstract: PURPOSE: To select another content of image processing by converting three- primary R, G, B signal obtained from a read original into a lightness signal, generating the histogram of the signals, analyzing automatically the histogram so as to discriminate the type of the original. CONSTITUTION: A lightness generating section 200 calculates lightness data close to a specific visual sense of human being based on R, G, B data. A 1st histogram memory 202 is used to simply obtain the lightness histogram of an original and 2nd histogram memory 204 is used to obtain the histogram of achromatic dots in the original. A minimum value circuit 212 and a maximum value circuit 214 detect a minimum value and a maximum value of the received R, G, B data, and a subtract circuit 216 obtains a difference between the minimum value and the maximum value. When a comparator 218 discriminates it that the difference is smaller than a prescribed level, the original data are discriminated to achromatic data and the write of the lightness data to the 2nd histogram memory 204 is allowed.  Thus, it is identified as to whether an original is a black/white original or a color original and its copy made is automatically decided to increase the copy speed of a black/white original.

Title: High voltage generating circuit
Inventor: MATSUMOTO MASAHIKO
IPC: H04N3/185
Filed: 1992-02-04
Abstract: PURPOSE:To enhance the response by increasing an electromagnetic energy transferred to a prescribed capacitor as a high output voltage drop is increased so as to omit the provision of a choke coil or a large capacitance of smoothing capacitor. CONSTITUTION:As an ON period of a switching transistor (TR) 15 gets longer, a larger electromagnetic energy is stored in a primary coil 6. The electromagnetic energy having been stored in the coil 6 is stored in capacitors 17, 18. When a high output voltage drop is increased in the circuit operation, an ON pulse width of a drive signal of the TR 15 is widened and the ON pulse width of a MOSFET is made narrow and a peak value of a flyback pulse as a collector voltage of the TR 15 is increased and a high output voltage is made stable. In this case, the relation of capacitance sets C1, C2 of the capacitors 17, 18 is selected to be C2>=C1. Thus, the collector voltage of the TR 15 is increased and fed to the coil 6 of the flyback transformer 5 and the boosting ratio of the transformer 5 is decreased by the increased voltage.

Abstract: PURPOSE:To prevent damage to yarn by arranging a plurality of bobbin holders in a line, changing over supplied yarns with a traversing device moving in parallel with holder shaft, and thereby lessening bend of the system during changing-over of yarn. CONSTITUTION:When a bobbin holder 3 is fully wound, a clutch brake 36 stops the traversing motion, and a solenoid valve is switched to allow the piston 26a of an air cylinder to move a traversing device 20 to the left following a guide bar 24 so as to attain the position mating with an empty bobbin 6' on the other bobbin holder 3'. At this time, the holder 3' is accelerated to a speed due to step of winding start, and the yarn a moves so as to mate with said empty bobbin 6' while being held by a yarn guide 23, and when yarn changeover is made and movement of the traversing device 20 is completed, a traverse cam roller 21 starts the traversing motion of the yarn a followed by pulse counting and winding operation. This changing-over while yarn is held at the yarn guide, in this manner, should lessen bend of the yarn to ensure that even a thin yarn is processed without risk of being cut.
