Inventor: SAKURAI SHINYA
IPC: C08L29/10
Filed: 1998-10-16
Abstract: PROBLEM TO BE SOLVED: To obtain a fluoroelastomer composition which gives a crosslinking product which retains its low-dusting properties in a plasma atomsphere, has such a heat resistance as to enable it to be used at high-temperatures, and is excellent in mechanical strengths and abrasion resistance by compounding a crosslinkable fluoroelastomer with a cocrosslinker excellent in compatibility and a polymerization initiator.

Title: Storage device
Inventor: SENGOKU SHINJI
IPC: G11B33/14
Filed: 1985-12-27
Abstract: PURPOSE:To detect the increase of dust on the periphery of a recording/ reproducing head or a disk as a recording medium by fitting a dust detector to a storage device to be used for an electronic computer, peripheral terminal equipment or the like for the electronic computer. CONSTITUTION:The dust detector 22 is constituted of a laser oscillator 20 and a laser receiver 21 and the laser oscillator 20 projects laser beams to the laser receiver 21. When the floating of a head 6 is normal, dust is not generated in the periphery of the head 6 or the disk 3, so that laser beams projected from the laser oscillator 20 are received by the laser receiver 21 as they are without being attenuated. If the head 6 or the disk 3 starts to be damaged, the floating of the head 6 is made unstable and abnormal and much dust is generated in the periphery of the head 6 or the disk 3, so that the laser beams projected from the laser oscillator 20 are attenuated and the attenuated laser beams are received by the laser receiver 21. The drop of an output from the laser receiver 21 due to the reception of the attenuated laser beams is detected by a detecting circuit 22A.

Abstract: PURPOSE:To quickly perform lock with simple circuit configuration even when an input frequency changes by controlling the oscillation frequency of a voltage controlled oscillator with a first voltage control signal and a second voltage control signal corresponding to the fluctuation value of the first voltage control signal. CONSTITUTION:The first voltage control signal Sd1 corresponding to a phase difference between an input signal frequency fi and the output signal frequency 0 of the voltage controlled oscillator 4 is inputted from a loop filter 3 to the voltage controlled oscillator 4.

Therefore, it follows that the voltage controlled oscillator is controlled with the second voltage control signal other than the first voltage control signal. In sush a way, the PLL circuit can be pulled in to a capture range even when the input signal frequency remarkably changes, and the lock can be performed in a short time with the simple circuit configuration.

Further, as the temp. measuring means is not necessary to directly fit to the raw material S, the productivity can be improved by simplifying the work.

Title: Information reproducing device, information recording device, recording medium used for information reproducing or recording using near visual field light beams, information reproducing method and information recording method
Inventor: OMI MANABU
IPC: G11B7/1387
Filed: 1998-10-19
Abstract: PROBLEM TO BE SOLVED: To further improve a recording density by using a reproducing and recording system using near visual field light beams. SOLUTION: A linear shaped edge 7 is formed on a sample glass substrate 6. When the substrate 6 is illuminated by near visual field light beams, intense scattered light beams are obtained when the edge 7 crosses orthogonally against the polarizing direction. When the edge 7 is made in parallel to the direction, the scattered light beams keep small. Thus, since the strength of the scattered light beams becomes different depending on the directional relationship between the formation direction of the edge 7 and the polarizing direction of the near visual field light beams, by using this effect, a high density reproducing/ recording device is obtained.

Abstract: PURPOSE:To always bring a peak position to the center of the observance period by generating a period signal specifying the length of a data period so that the peak position approaches the central position of the observation period in a succeeding data period in response to the deviation direction from the center of the peak position and its degree. CONSTITUTION:Whether or not the peak position of a correlation peak of a correlation signal between a reception signal and a code series with a prescribed code length is within the observation period set tin the data period, the direction of deviation from the center of the observation period and its degree are decided. Then a period signal specifying the length of a data period so that the peak position approaches the middle position of the observation period in a succeeding data period in response to the deviation direction from the center of the peak position and its degree is generated. Thus, after the period is established once, the length of the succeeding data period is adjusted in response to the location of the peak in the observation period of the data period and the peak position is controlled always to be in the center of the observation period.
