Title: Image reader
Inventor: OISHI KENJI
IPC: H04N1/04
Filed: 1999-06-09
Abstract: PROBLEM TO BE SOLVED: To fast read an image by allowing 1st and 2nd motors having simultaneously drivable control means to move a sensor which converts optical image information into an electrical image signal and a lens on which an image recorded on an original is formed relatively in a 1st direction with respect to the original.

Title: Method and device for controlling motor actuator
Inventor: MIZUNO KUNIO
IPC: F24F13/10
Filed: 1996-06-04
Abstract: PROBLEM TO BE SOLVED: To make the deviation in driving position as small as possible by storing a phase a predetermined value before a driving phase at the stopping of operation and restarting the operation from the stored driving phase. SOLUTION: When a control is started, it is judged whether the supply voltage is within a predetermined range or not. In the case that the supply voltage is below the specified range, it is judged that the supply voltage is abnormal and then it is judged whether a motor actuator is being driven or not. When the motor actuator is being driven, the operation is stopped and the data about a driving step at the stopping of operation is stored as a variable S1 is a memory built in a CPU. After that, '1' is subtracted from the stored value and then the calculated value is stored as a new value of the variable S1.  Then, on the assumption that there is a deviation in position of the stepping motor, a variable 'm' for obtaining an estimated value S for the deviation in position of the stepping motor is set to '1' and the variable 'm' is added to the estimated value S for the deviation in position at this point of time and then the up-to-date estimated value S for the deviation in position is obtained. When starting the operation again, the operation is restarted from the driving step stored as the variable S1. By this method, the deviation in position can be lessened to the utmost.

Title: Magneto-optical recording and reproducing device
Inventor: MAZAKI YUTAKA
IPC: G11B5/02
Filed: 1987-06-30
Abstract: PURPOSE:To contrive the miniaturization of a power unit by selecting the intensity of a magnetic field giving effect onto the recording/erasure of leaked magnetic field generated from an objective lens driving device to be a prescribed relation with respect to the intensity of the magnetic field required for recording/erasure at a spot position on a recording medium face. CONSTITUTION:A laser beam is radiated to a point O on a recording medium 100 through an objective lens 211 to cause a current to flow through a coil 301a of an electromagnet 301 and to apply the magnetic field Hw generated thereby to the point O to record information and read out the information through the radiation of a weak laser beam. Moreover, a current is given in the coil 301a to apply a magnetic field He to the point O, thereby erasing the information through the use of an intensive laser beam. in this case, the power consumption consumed in the coil 301a of a device 300 is reduced by selecting the arrangement between the magnetic circuit of an objective lens driving device 200 and a magnetic field application device 300 so as to obtain the relation of Hm=1/2(Hw+He), where Hm is the magnetic field intensity, thereby reducing the heat production. Thus, the small-sized device is realized.

Abstract: PURPOSE:To widen an effective magnetic-flux variation range by enabling a unidirectional switching element to be used by applying a pulsating current to the primary side of a transformer through a switching circuit and applying a reverse bias amgnetic field to the core of the transformer prior to primary- side conduction. CONSTITUTION:The output of an AC power source 2 is converted by a rectifying circuit 3 into a pulsating current, which is applied to a primary winding 1a through a unidirectional switching circuit 4. The output voltage of a secondary- side smoothing circuit 5 is detected by a detecting circuit 7 to control the on- period of the circuit 4 through a primary-side conduction-phase-angle control circuit 6.
