Title: Focus servo controller
Inventor: NISHIDA NORIO
IPC: G11B7/095
Filed: 1993-10-27
Abstract: PURPOSE:To improve the precision of a focus servo and to reduce a cost of an optical disk drive by controlling an offset voltage so that an integration value of a reflection light quantity difference at every prescribed number of revolutions of an optical disk becomes maximum. CONSTITUTION:The difference of the reflection light quantity between the mirror surface of the optical disk 10 of a sample format and a pit is detected by a quadripartite detector PD 22. The output of the PD 22 is inputted to a head amplifier 23, and an RF signal and a focus error signal FE are latched by latches 27-29, 32 through A/D converters 25, 31. By a PSP 32, the reflection light quantity difference is integrated at the every prescribed number of revolutions of the optical disk based on an ADRF signal latched by the latches 27-29, and a drive amplifier 35 is controlled through a D/A converter 34 so that the integration value becomes maximum. Thus, the automatic offset adjustment is performed, and the precision of the focus servo is improved.

Title: Motor-driven controller and zoom lens operating device
Inventor: MIZUMURA HIROSHI
IPC: H02P29/00
Filed: 1999-09-22
Abstract: PROBLEM TO BE SOLVED: To realize constant-speed automatic zoom function and to apply such technique to other motor-driven controller by converting a zoom position signal commanded by the pushing/pulling operation of an operation bar to a speed signal in the lens operating device of a uniaxial two-operation servo control system. SOLUTION: A lens controller outputs a zoom position command signal in accordance with the operating position of the operation bar. A CPU 86 controls the driving of a zoom motor 72 based on the zoom position command signal received through an A/D converter 84. By pushing a constant-speed automatic zoom switch 30 in the midst of the pushing/pulling operation of the operation bar 22, the variation of the zoom position command signal at such a time is stored and the designation of speed is maintained. By pushing the switch 30 again in the midst of constant-speed operation, a zoom lens 62 is stopped. By pushing the switch 30 further, the zoom position is restored to the designated position of the bar 22.  It is conceivable to restore control by the operation bar when the designated position of the operation bar is aligned with the present position after stopping the constant-speed operation.

Title: Data processor
Inventor: IMABAYASHI TAKEHIRO
IPC: G06F13/28
Filed: 1990-10-08
Abstract: PURPOSE:To execute other processes by a CPU during a DMA without providing a sub CPU and a shared memory by separating the CPU from an internal bus by a bus control means while executing the DMA. CONSTITUTION:When a DMA control part 2 controls a data transfer, a bus mediation part 5 controls a bus control part 6. And while making the output sides of a buffer part 6-1 and a latch part 6-2 a high impedance and separating a CPU 1 from an internal address bus 7 and an internal data bus 8, the data transfer between an I/O control part 4 and a memory 3 is executed. Therefore, the CPU 1 can access another I/O control part and memory 10. And even during the DMA, the CPU 1 can execute only the first right operation by latching an address and data in the latch part 6-2. Thus, without using the sub CPU and the shared memory, it is possible to separate a bus executing a DMA transfer from the CPU 1, so the CPU 1 can execute other processes.

Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device constituted so that the service lives of a developing means and developer are prolonged and image quality is prevented from being deteriorated because of color staining. SOLUTION: This image forming device is provided with plural electrification means 201, plural exposure means 301 being the latent image forming means and plural developing means 401 near an image carrier in turn and constituted so that a toner image is successively formed on the image carrier. When a developing process is executed by the smaller number of developing means 401 than the plural developing means 401, the developing means which is not used for developing is not pressed. Thus, time required for driving the image carrier is also shortened and the service lives of the electrification means, the developing means and the developer are prolonged. Besides, since the color staining is prevented from occurring by the toner of the developing means which is not required, the excellent image quality is obtained and power consumption is saved.
