Title: Optical gyro
Inventor: NUMAI TAKAAKI
IPC: H01S3/083
Filed: 1998-10-19
Abstract: PROBLEM TO BE SOLVED: To enhance optical coupling efficiency without requiring any special optical system by providing a ring resonant semiconductor laser where the light propagates circulatingly, and a total reflection face for laser light and arranging a light detecting means within the leaking distance of evanescent light present on the total reflection face. SOLUTION: An optical gyro comprises a ring resonant semiconductor laser 1 where the light propagates circulatingly, and a laser light detecting means 2. When a current is injected from an anode 11 to the laser 1, a reverse bias voltage is applied to the light detecting means 2 from an anode 21. An active layer 12 and an absorbing layer 22 comprise an InGaAsP film sandwiched by optical guide layers of InGaAsP which are sandwiched by clad layers of InP. Gain of total reflection is lower by an amount corresponding to mirror loss than that of other mode. Consequently, oscillation begins at a low injection current level and oscillation in other mode is suppressed. Distance between the laser 1 and the light detecting means 2 is set equal to the leaking distance of evanescent light.

Abstract: PURPOSE:To reduce frictional resistance moment by a large margin by providing a supporting seat that stretches out in a direction perpendicular to a shaft and having a cylindrical section on both side faces nearby the center of the axial length of a bearing shell, and a bearing stand that supports the supporting seat. CONSTITUTION:In an automatic aligning type journal bearing, a supporting seat 5 that stretches out horizontally and in a direction perpendicular to a shaft 1 on both side faces nearby the center of the axial length of a bearing shell 2 composed of an upper half part 2a and a lower half part 2b when divided into two parts and having a cylindrical section, and a bearing stand 6 that supports this supporting seat 5 are provided. At the time of machining the supporting seat 5, after the supporting seat is machined to a cylindrical shape keeping the bearing shell 2 in a body, the bearing shell is divided into upper and lower two parts. Since bearing load is supported by the cylindrical supporting seat having a short turning radius, frictional resistance moment that acts on the bearing when it is in motion is reduced by a large margin. Therefore, the supporting seat is forced to follow up vertical axial eccentricity to perform automatic aligning by means of this cylindrical supporting seat.

Filed: 1996-10-18
Abstract: PROBLEM TO BE SOLVED: To resolve such inconveniences that, even if the number of sector regenerated continuously is large or small, probability when an absolute address is not correctly obtained should be equalized between the both, and when generation of errors is detected by a threshold set irrespective of the number of sector from which data is reproduced, many errors are generated when a great number of sector is continuously reproduced.

A ratio of the number of times that an absolute address is not incoincide with an address of an objective sector to the number of sector from which data is reproduced is computed every sector. Next, when the ratio value of each sector computed exceeds a first threshold value, errors are reported and an objective sector is accessed again.

Filed: 1989-11-17
Abstract: PURPOSE:To reproduce a signal level faithful to the transmission level of a training signal by detecting a signal part having the specified frequency characteristic of the received training signal and controlling a gain by means of a different set point in a period when the signal concerned is detected. CONSTITUTION:A switch means 106 supplies the output set point at the time of detecting an AB pattern or an output set point at the time of random data, which is the exception of the set point to a subtracter 104. An AB pattern detector 105 detects the AB pattern by using the characteristic of a frequency spectrum among input signals, connects the switch 106 to the side of the output set point at the time of detecting the AB pattern while an AB pattern signal concerned is detected and connects the switch 106 to the side of the output set point at the time of random data except for the time. The output set point at the time of the AB pattern is set to be smaller than the output set point at the time of random pattern by a known rate (about 3dB), for example. Thus, the output signal level comes to the faithful to the transmission level as illustrated.
