Title: Objective lens driving device, optical head and optical information recording and reproducing device
Inventor: YASUDA AKIHIRO
IPC: G11B7/095
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To suppress the resonance of a rolling mode employing a simple constitution in an objective lens driving device used in an optical disk recording and reproducing device. SOLUTION: A tracking driving force is resolved into two parts by arranging two magnets 2a and 2b vertically. The magnets 2a and 2b operate on a movable body while sandwitching the center of gravity of the body so that the resonance of a rolling mode caused by the off-centered gravity of the body is suppressed. Moreover, for a thinner type objective lens driving device, the off-centered gravity of the body is compensated for and the resonance of the rolling mode is suppressed by varying the strength of the magnetic field of the magnets and the rigidities of the wires and a damper material.

IPC: G11C8/04
Filed: 1988-01-29
Abstract: PURPOSE:To transfer the data on an optional address to another register during the serial output of said data by setting a 2-step selection switch between the bit line pairs and the register groups. CONSTITUTION:The switch circuits 5a and 5b select one of two bit line pairs 2a/2a' and 2b/2b' by the selection switch signals phiGa and phiGb for bit line pairs and also connect the corrected output set after the selection to the corresponding pair. Then the data is transferred to one of register groups 6a and 6b by the register selection switch signals phiSa and phiSb. In such a way, a 2-step selection switch is set between the bit line pairs and the register groups. As a result, the optional data on two pairs bit lines can be transferred to the register groups and the data on an optional address can be transferred to another register during the serial output of said data. Furthermore the limitation of the register transfer cycle can be released without increasing the number of register groups compared with the number of bit line pairs.

Filed: 1994-02-17
Abstract: PURPOSE:To transmit the pulse signals, etc., without changing the existing wiring of a flow meter by outputting the detected request signal to the outside via the data signal line of a data storage means. CONSTITUTION:A flow rate pulse output means 33 always outputs the flow rate pulse to the outside via the signal lines A and B. Then each power supply is switched on in its starting state, and an ON state, i.e., a request signal of a power line C is detected by a request signal sensor means 40 of a controller 30. Thus a data output means 39 outputs the data E stored in an output data storage means 34 via a signal line A, for example, and also outputs a clock pulse F of a clock pulse transmitter means 38 to a local computer via the other signal line B for synchronization of the data signals. When the transmission of the data E and the pulse F are finished and a flow rate pulse is inputted, the controller 30 applies the correction of device difference and temperature to the pulse signals received from the pulse transmitters 24 and 25 by revolutions of a flow meter 21. These corrected pulse signals are transmitted to the local computer from the means 33.
