Title: Method and device for adjusting focusing position
Inventor: WATANABE KATSUYA
IPC: G11B7/09
Filed: 1990-05-24
Abstract: PURPOSE:To record and reproduce a signal with superior quality on a recording medium by approximating the relation of reproducing signal amplitude for a targeted position when the targeted position of focusing control is varied by a cubic function, and adjusting the convergence state of an optical beam based on an approximated function. CONSTITUTION:The reproducing signal amplitude in accordance with the varied convergence state of the optical beam 6 is stored in a RAM 46 as a numeric value. A microcomputer 42 calculates adjusting data for travel to the optimal focusing position by processing the value stored in the RAM 46, and adds a result on a focusing control system via a D/A converter 41 and a synthesis circuit 43, and sets the convergence state of the optical beam 6 on the recording medium at the optimum state. Therefore, it is possible to automatically adjust the focusing position even when an unknown force is applied from the outside or the state of a focusing control system is changed due to change of lapse of time, etc. In such a way, it is possible to always converge the optical beam 6 correctly on the recording medium 10, and to perform the recording and reproduction of the signal with high quality.

Title: Ac drive system for liquid crystal display device
Inventor: SUGIMOTO TAKAYUKI
IPC: H04N9/12
Filed: 1988-05-31
Abstract: PURPOSE:To prevent production of flicker at a low drive voltage with simple circuit constitution by varying the DC component of a video signal and its amplitude in response to the polarity of the video signal and making the brightness of a liquid crystal panel in both the polarities equal to each other. CONSTITUTION:The display device consists of 6 longitudinal elements and 6 lateral elements, in total 36 elements, and a positive video signal 2 is applied to a source of a thin film transistor(TFT) in case of displaying a video signal of an odd number field and in case of displaying a video signal of an even number field, a negative video signal 3 is applied. Since the brightness is lower in case of the driving by the positive video signal than that in case of the driving by the negative video signal based on the characteristic of the TFT, the DC level (black level) of the negative video signal 3 and the amplitude (gray level, white level) of the negative video signal 3 are set larger than the inverted positive video signal level to make the brightness on the panel equal to that at the application of the positive video signal. Thus, the change in the brightness of the liquid crystal display device is not caused in case of the odd and even number fields. Thus, production of flicker is prevented and the constitution of the drive circuit is simplified by lowering the drive voltage.

Title: Information recording and reproducing device
Inventor: HORIUCHI TADASHI
IPC: G06F12/08
Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To obtain an information recording and reproducing device provided with a data processing function which quickly executes at least write from a cache memory to a recording medium. SOLUTION: When a write request is outputted from a host computer 10 to a CPU 8 of an optical disc device 1, a CPU 8 judges whether the address of unwritten data in a cache memory and the address of received address are continuous or not by a LBA judging means 8-2 after transferring write data in a write command to the cache memory 6, and if they are discontinuous, the CPU 8 judges whether they are discontinuous within a prescribed range where the time required for access with latency is shorter than the time required for seek or not by a LBA range limiting means 8-3. If they are continuous or they are discontinuous within the prescribed range, the data processing to collectively write data without seeking individual addresses is performed to reduce the frequency of seek in comparison with seek of individual addresses, and the write processing time is considerably shortened.

Title: Electrostatic image
Inventor: HASEGAWA TETSUO
IPC: G03G9/087
Filed: 1977-11-11
Abstract: PURPOSE: To form a long lasting electrostatic image of negative polarity, by forming a toner with a binder containing an isobutylvinylether-vinyl chloride copolymer.  
     CONSTITUTION: A toner binder is prepared by mixing an isobutylvinylether-vinyl chloride copolymer (preferably at a monomer ratio of 1:9W5:5 by wt.) with a resin, siuh as polystyrenes, polyvinylchloride, or polyester. This binder is dispersed in an organic solvent together with a colorant, then, the solvent is evaporated, and the toner is formed by pulverizing the solid thus obtained. Since the above copolymer is colorless, it does not hinder expression of the specified hues, such as yellow, magenta, or cyan, when it is used in a color toner for use in color electrophotography, electrophotographic textile printing, or the like.

Title: Semiconductor laser device and manufacture thereof
Inventor: MUTO KATSUHIKO
IPC: H01S5/00
Filed: 1985-06-24
Abstract: PURPOSE:To obtain high output power, by forming a current blocking layer with a high resistance material, whose main component is carbon. CONSTITUTION:On an N-type GaAs semiconductor substrate 9, an N-type AlGaAs layer 10, a GaAs active layer 11 and a P-type AlGaAs layer 12 are sequentially grown. A stripe mask 13 of SiO2 having a width of several mum is formed on the P-type AlGaAs layer 12. Thereafter, introduced CCl4 is activat ed or decomposed by using high frequency. Etching is performed by using CCl4 gas 14. Thus, both sides of the stripe mask 13 are removed. A carbon component is deposited on the removed parts at the same time. Therefore, a current block ing layer is formed by one process, and the process is simplified. Epitaxial growing is not required on an irregular surface. An epitaxial growing process is not required after etching. Since the high resistance layer of the current blocking layer is formed at the same time, deterioration in interface char acteristics is eliminated. Thus improvements such as the reduction in threshold current and the implementation of high optical output power can be realized.
