Title: Pll frequency synthesizer
Inventor: JOKURA ATSUSHI
IPC: H03L7/191
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To reduce frequency channel intervals and to speed up convergence by inputting the output of a frequency divider to a phase comparator as a feedback signal and generating the control voltage of a voltage control oscillator, based on a phase difference signal. SOLUTION: An external oscillation frequency signal fr is inputted to the phase comparator 2 and a part of the voltage control oscillator VCO5 is inputted to the comparator 2 as the clock of FF10. VCO5 is inputted to the frequency divider 7 composed of n-pieces of frequency dividers 71-7n, and it is inputted to the comparator 2 through an OR gate 8. Then, respective FF61-6n permit signals generated when a channel switch operation is taken place in a control circuit 9 to be reset inputs and make the signals fr clock inputs. First FF61 sets an operation signal S to be D-input and 62-6n of next and succeeding stages sequentially input the output of the former stages. Respective FF61-6n are cascade-connected and they transmit enable signals EN1-EN2 to the frequency dividers 71-7n as the feedback signal at timing shifted at every period.

Title: Optical recording medium
Inventor: NAKAKUKI HIDEO
IPC: G11B7/254
Filed: 1998-07-29
Abstract: PROBLEM TO BE SOLVED: To obtain an optical recording medium which is free from deterioration by repetitive overwriting, such as the degradation in jitter characteristics, the deterioration at the beginning ends and terminals of sectors, the degradation in contrast and the occurrence of a burst defect and is excellent in an overwriting shelf characteristic and erasing characteristic by providing both sides or one side of the recording layer of the medium with a layer consisting of a carbide so as to bring this layer into contact therewith. SOLUTION: The representative constitution of the component members of the optical recording medium is obtd. by laminating a first dielectric layer, carbide layer, recording layer, second dielectric layer and reflection layer in this order on the transparent substrate. The mass transfer of the recording layer is suppressed and the diffusion of sulfur from the dielectric layers to the recording layer is prevented by forming the carbide in contact with the recording layer, by which the deterioration by the repetitive overwriting may be ameliorated. The reason thereof lies in that crystallization is accelerated by the carbide layer to enable the rapid crystallization of the recording layer. The layer consisting of the carbide is selected from silicon carbide, titanium carbide, tungsten carbide, and tantalum carbide.

Abstract: PURPOSE:To prevent the deterioration of a recording medium after repetition of recording and erasing of optical information by forming an underlying film on the recording medium, then subjecting the surface thereof to sputter etching to remove an oxide film, etc., thereby improving and uniformizing the adhesiveness of the recording medium. CONSTITUTION:The underlying film 12, the recording medium film 14 and a protective film 15 for said recording medium film are successively formed on a substrate 10. The boundary 13 of the underlying film is subjected to the sputter etching prior to the formation of the film 14 and while the vacuum at the time of the sputter etching is maintained, the film 14 is formed. The natural oxide layer formed on the surface of the underlying film and the impurities, etc., sticking thereto are completely removed if the underlying film is subjected to the sputter etching in the above-mentioned manner, by which the boundary of the underlying film of the recording medium is uniformized. Since the formation of the recording medium to be formed is continuously executed under the same vacuum conditions, the at mospheric pollution of the boundary is obviated and the adhesive power of the boundary is improved.

Title: Neutral steering angle estimating device
Inventor: TANABE MASAHIKO
IPC: B62D113/00
Filed: 1989-08-23
Abstract: PURPOSE:To reconcile a high response during low speed running with a high steering angle estimating precision during high speed running by a method wherein a correction steering angle is contained in a computing condition of a varying neutral steering angle estimating value, and a lenient computing condition for a neutral steering angle estimating value is set during low speed running and the more a speed is increased, the more the computing condition is severely set. CONSTITUTION:In a means (d) to set a computing condition responding to a car speed, a neutral steering angle estimating value computing condition in which at least a handle steering angle is within a correction steering angle range and a running distance within this range exceeds a set value is liniently set when a car speed is low, and the more a car speed is increased, the more the computing condition is severely set. In a neutral steering angle estimating value computing means (e), when a handle steering angle obtained by a handle steering angle detecting means (a) and a running distance by a running distance detecting means 6 satisfy a computing condition responding to a car speed, based on a handle steering angle detecting value obtained during running in which a correction steering angle condition is satisfied, a neutral steering angle estimating value is computed. Thus, right after the starting of running and when a car speed is low, a neutral steering angle estimating value is set rapidly with excellent response, and during middle and high speed running, the neutral steering angle estimating value is set with gradually increasing precision.

Filed: 1987-09-01
Abstract: PURPOSE:To remove skip and fog, etc., and to improve image quality by providing a density setting means for setting the density of a copied image, respectively corresponding to plural original colors, and forming a set monochromatic copied image by the set density. CONSTITUTION:Red, black and green are selected according to the color of the original by using an original color selection switch 31. Then the setting of the density is executed according to the position obtained by sliding the density setting knob 32. When the knob 32 is slided toward thick, density control voltage rises and the density increases. If the color is light the skip occurs and if it is too dark the fog occurs. Since the proper density is different every color, the setting of the density is executed while switching colors. Thus, the skip, the fog, etc., in the copied image are removed and the image quality can be improved.
