Title: Optical disk medium
Inventor: MORI KUNITAKA
IPC: G11B7/24
Filed: 1985-06-06
Abstract: PURPOSE:To prevent a circuit from malfunctioning by recording a clock signal which indicates a sector position as a diffracting means which performs optical reflection or transmission on radial lines of a sector groups arranged radially. CONSTITUTION:An optical disk 1 is provided with grooves 2 for track following, sector marks 3 which has track and address information on respective tracks, and sector indicators 5 where a diffraction grating is formed by arranging plural sector indicator grooves 4 which have heads and tails on prolongations of a sector mark group positioned on the medium radially in constant position relation with the sector mark group in a peripheral direction at constant pitch. Sector marks 3 recorded on the grooves 2 for track following are read with laser light converged by an optical disk device, but variation in the quantity of reflected light due to diffraction is obtained on a sector indicator 5 even with ordinary light which is not converged. Thus, the clock signal which indicates a recorded sector position is provided as a diffracting means, so a clock signal for controlling the recording and reproduction of the optical disk medium is obtained stably and easily.

Title: Image coding decoding device and image decoder
Inventor: SUGIYAMA KENJI
IPC: H04N19/126
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To reduce a data amount to be sent by providing a means to detect a change in an activity, improving the image quality of a block with a higher activity than that of surrounding blocks through more minute quantization steps and applying variable length coding to class information of an adaptive quantization. SOLUTION: An activity detector 6 detecting a change in the activity detects a block (edge part or isolated image) with a higher activity than that of surrounding blocks and an adaptive quantization device 3 applies more minute quantization steps to a detected block. Thus, mosquito noise is reduced and image quality deterioration is avoided. Furthermore, class information of the adaptive quantization is subjected to variable length coding by a variable length coder 4 so as to reduce a transmission data amount so as to attain more proper adaptive quantization.

Title: Servo controller
Inventor: TAJIMA HITOSHI
IPC: G05D3/12
Filed: 1988-05-20
Abstract: PURPOSE:To perform the servo position/speed control in a short tact time by using an acceleration correcting means to change the acceleration of a commanded speed based on the difference between a commanded position and an actual shift position. CONSTITUTION:The transfer of data is carried out between the control units 1 and 2 consisting of the CPUs, etc., via a 2-port RAM 3. At this time point, the unit 2 reads the droop value and calculates the optimum acceleration alphaM from this droop value. Then a speed VA=VN-1+alphaM is calculated (VN-1: preceding control command). An acceleration table is included into a program to the droop value and the alphaM is read out to the read droop value by reference to the acceleration table. For the value of said table, the alphaM is decreased in response to the increase of the droop value. In such a constitution, the tact time is shortened without increasing the motor load.

Inventor: MIYAMOTO YOSHIHIRO
IPC: H04N5/335
Filed: 1984-06-15
Abstract: PURPOSE:To improve the quality of a picture and to miniaturize an image pickup device by forming a detecting element where a forbidden band of a semiconductor substrate, i.e., the cut-off wavelength of the photodetection sensitivity is changed monotonously as to one direction onto the semiconductor substrate face. CONSTITUTION:The detecting elements 11 are arranged in a form of a two- dimension matrix on a semiconductor substrate face and one direction of the arrangement is matched to the direction where the cut-off wavelength is changed. The detection elements 11 arranged in this way have identical photo sensing characteristic as to a direction where no cut-off wavelength is changed ( in longitudinal direction in figure) and show a characteristic where the band is shifted sequentially as shown in S1, S2, S3-Sn in figure (c) as to a direction where the cut-off wavelength is changed (in lateral direction in figure). Thus, the signal obtained from each detection element 11 by the scanning is subject to time series multiplex in the order of arrangement every element having an equal spectral sensitivity characteristic, a one0dimensional array is formed and the result is detected by a detector 12.

Abstract: PURPOSE:To make an optical recording and reproducing device compact, by using a cylindrical information carrier to irradiate the light beam, which is emitted from an optical system, with a spot of a diffraction limit, which is determined by the number of apertures of the optical system, at the recording time. CONSTITUTION:The light flux emitted from a light source 1 is made into a parallel light flux by a coupling lens 2 and is incident to a recording object lens 3. Next, the light emitted from the object lens 3 is condensed to a spot of a diffraction limit determined by the number of apertures of the object lens 3 and is irradiated onto a rotating cylindrical recording drum 4. Since the optical system is fed in a constant speed in a direction parallel to the recording drum, a spiral track 5 is formed on the recording drum. Thus, a bulk recording and reproducing device is made compact in three dimensions.

Abstract: PURPOSE:To compensate a deterioration in S/N accompanying the lowering of input electric field intensity by detecting and transferring own S/N to another station and then by varying the own modulation degree according to information on S/N sent from the station. CONSTITUTION:In radio equipment 1, a received signal is demodulated 5 and the demodulated signal is passed through voltage control low-frequency amplifier 6 and has a noise of a partial band detected by noise detector 8 to develop an S/N voltage proportional to S/N. This voltage is converted into a change in frequency by data modulator 14 and the change is amplified by voltage control low-frequency amplifier 12 and then modulated 11 and amplified 10 before being sent out. In party-side radio equipment 1', this S/N voltage is regenerated by data demodulator 9 and according to the voltage, the gain of amplifier 12 is varied to vary the modulation degree of modulator 11. If S/N of equipment 1 deteriorates, the modulation degree of equipment 1' is increased with the S/N voltage and when S/N improves, the demodulation degree is decreased, so that the deterioration of S/N due to fluctuations of an input electric field can be improved.
