Title: Optical disk device
Inventor: IWAMOTO TOSHITAKA
IPC: G11B7/24
Filed: 1984-03-27
Abstract: PURPOSE:To use selectively a means which records erasably information on a medium and a means which records unerasably information by giving a physical change to the medium. CONSTITUTION:It is possible to drill a hole 9 by irradiating the laser light 1 of a high level. A sector is divided into an index part ID and a data part DA, and the part DA is divided into two parts SA-1 and DA-2. The part ID has no change of its contents and therefore records unerasably information in a write mode with a light spot having the optical power set at a drilling level Pf. Otherwise the information is already recorded to a stamper, etc. In case the important information to which the erasion is not allowed is written through the part DA, an information protecting pattern is written by the light spot set at the level Pf. Then the information is recorded at a photomagnetic writing level Pb or a writing level Pd making use of the physical deterioration. Thus the information can be protected by recognizing the information protecting pattern of the part DA-1 preceding the important information on the part DA-2 even in case the corresponding sector is erased by mistake. Furthermore, the part DA can be used again excepting the drilled area by releasing a protection mode.

Abstract: PROBLEM TO BE SOLVED: To simplify a construction work for a tank to be constructed and an existing tank and maintain corrosion preventing effect at a low cost for a long period of time by interposing a member of zinc or a zinc alloy between an outdoor tank roof plate supported by a supporting material and the supporting material. SOLUTION: Plate-shaped members 10 made of zinc or the like interposed between roof frame rafters 5 and roof plates 6 for a petroleum storage tank 7 are fixed by the dead weight of the plates 6. Or at least a part of one side of each of the members 10 is mounted using an adhesive and the roof plates 6 may be placed and fixed onto the members 10. According to such a method, the members 10 of zinc or members of a zinc alloy both has a lower potential than the plates 6 comprising steel plates or iron plates, and hence the plates 6 have current anodic functions, and a galvanic circuit is formed between the plates 6 supported by the members 10 of zinc or a zinc alloy, which serve as anodes, and the members 10, and hence corrosion prevention current from the circuit effectively prevents corrosion of the plates 6.

Title: Method and apparatus for calibration of printer, and printer
Inventor: FUKUDA KOJI
IPC: H04N1/60
Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To accurately calibrate a printer. SOLUTION: A gray patch of a test print is separated to three colors and subjected to photometry by a densitometer 35. A magenta density, a yellow density and a cyan density are stored in a density data memory 32c. A correction energy amount for magenta is obtained by a calibration-operating processing part 38 on the basis of a difference between the magenta density and a target density. A density change of the other yellow and cyan when the correction energy amount is used is estimated. A correction energy amount for restricting the estimated density change is obtained for each color. Similarly, the correction energy amount for each of yellow and cyan is obtained from a difference of an estimated density and a target density and, the estimated density of the other colors at this time is obtained.  The correction energy amount which reduces the difference of the photometric density or estimated density and the target density is obtained by repeating the processes. In comparison with the case where the density of a single color print is used, the calibration result is obtained more accurately.

Title: Method for monitoring system state
Inventor: IIJIMA KENJI
IPC: H04L12/40
Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To attain data transmission capable of preventing the generation of overlap in the transmission timing of plural devices by setting up the transmission periods of broadcasts of respective devices to mutually different values so that the transmission period of a certain device is not an integral multiple of another device. SOLUTION: Control devices 12 to 14 are mutually connected through a transmission line 11. Each of the devices 12 to 14 transmits the state of its own device to the other devices by a broadcast at a fixed period through the line 11. The transmission periods of broadcasts of respective devices 12 to 14 are set up to mutually different periods by transmission timing processing parts included in respective devices 12 to 14 so that the transmission period of a certain device out of the devices 12 to 14 is not an integral multiple of either one of devices 12 to 14. Consequently the generation of overlap in the transmission timing of broadcasts can be prevented and the omission of receiving processing which may be generated at the reception of a broadcast and the delay of receiving processing can be also prevented.
