Patent JP-H08191586-A (JP)
Title: Motor
Inventor: ISOBE TOMONORI
IPC: H02K29/03
Filed: 1995-01-09
Abstract: PURPOSE: To prevent the bias of the delay in detection of a signal owing to the through of a chopping signal and to suppress the hunting of a control circuit, extraordinary vibration of a rotor, etc., by correcting the generation timing of the chopping signal on the occasion when the rotational position of the rotor comes to a prescribed position. CONSTITUTION: A difference computing part 12 determines a difference between a speed signal (a signal showing the number of revolutions of the rotor of a motor) outputted from a speed detecting part 11 and a speed specification (a value showing a speed) given from outside. A chopping signal generating part 13 outputs to an electrification control part 10 a chopping signal for an ON/OFF signal of which the ON duty is controlled in accordance with the output of the difference computing part 12, and thereby the ON/OFF signal outputted to an inverter circuit 2 from the electrification control part 10 is subjected to chopping. A correcting part 14 corrects the generation timing of the chopping signal generated in the chopping signal generating part 13, on the occasion when the rotational position of the rotor comes to a predetermined position.

Title: Magnetic recording and reproducing device
Inventor: IWASAKI KEIJI
IPC: G11B15/28
Filed: 1992-01-08
Abstract: PURPOSE:To contrive miniaturization and light weight of the device by obtaining clutch force at the time of reproducing in the reverse rotation in utilizing a permanent magnet of a capstan motor and a hysteresis plate. CONSTITUTION:At the time of reverse reproducing, because of no clutch means provided inside a supply reel base, force for preventing the rotation of the supply reel base due to the tension of a magnetic tape is worked upon a capstan gear 40. Now, since the gear 40 and the hysteresis plate 39 are freely rotatively fitted to a capstan shaft 30 by magnetic force of the permanent magnet 35, slippage takes place between the plate 39 and the shaft 30. Consequently, the magnetic tape cannot be taken up by force more than torque generated by the magnet 35, and take-up torque of the supply reel base is kept constant. At the time of normal recording and reproducing, the magnetic tape fed from the capstan is taken up by a take-up reel. At this time, no slippage takes place between the magnet 35 and the plate 39. By this method, since a magnet clutch means is not required in the supply reel base, the device can be miniaturized with light weight.

Abstract: PURPOSE:To measure a sample consisting of light element with high sensitivity by placing a movable mask for shielding an X-ray between an X-ray detector set in a transmitting position and a sample to partially shielding the X-ray incident to a detector. CONSTITUTION:An X-ray bundle 1 is converged and collimated by a condensing mirror 2 into an X-ray bundle 3, and incident into a sample 4. The X-ray transmitted to the back of the sample 4 passes a mask 5 and reaches a detector 6. The signal X-ray 8 detected there is differed in component depending on the position of the mask 5. When it is situated in the position just shielding an X-ray 7, a slightly deflected X-ray is detected. This corresponds to a refracted on reflected X-fay. Namely, a contrast can be provided when no absorption is principally present. In case of a small absorption contrast, the statistical error of X-ray count signal is minimized even when the total intensity of the scattered beams is lower than the quantity of the absorbed X-ray, and a highly sensitive measurement can be preformed.

Abstract: PURPOSE:To drive the titled circuit with a simple circuit and to shorten an access time by separating X system, Y system address signal generator circuits while retaining said circuit in common on an address signal line concerning a circuit suitable for an address.multiplexer system dynamic MOS memory. CONSTITUTION:In case of the X system an outer address signal An is inputted into a Y system address signal line 4 through a X system inner address generator 1X, X system width circuit 2X, X system switch circuit SWX, and -SWX, and in case of the outer address signal An of the Y system, the signal is also inputted to the Y system address signal line 4 through circuits 1Y, 2Y, SWY, and -SWY.
