The reflected light reversely advances so as to be reflected by the beam spliter, and is made incident on a detecting optical system, so that an information signal, a track error signal, a focusing signal, and a focusing error, signal, etc., can be obtained. As to the light spot having the astigmatism; the spot on the medium 6 is controlled to become the elliptic spot having the major axis or the minor axis in the track direction in the case of erasing or reproducing the information. Thus, the excess light is not required to irradiate an adjacent track in the case of erasing and the resolution of the information bit is improved in the case of reproducing.

Abstract: PROBLEM TO BE SOLVED: To eliminate a discontinuous part caused by the variance of the values of respective bits by obtaining the values of the respective bits of a D/A converter taking charge of the upper bits as correction data in a circuit realizing high resolution by using two inexpensive D/A converters. SOLUTION: The values of the respective bits of the 8-bit D/A converter 12 taking charge of the upper 8 bits are stored in a ROM as the correction data.

Abstract: PURPOSE:To measure a flow having intense three-dimensional property in a short time by making two sheet lights having the different wavelengths scan at the different speeds, independently picking up the images of the scattered light with two image sensing devices, and comparing and operating the lengths of the loci of obtained particles. CONSTITUTION:Sheet lights 101a and 101b are laser lights having the different wavelengths and are moved in the direction of (x) at speeds Va and Vb.

Abstract: PROBLEM TO BE SOLVED: To zoom up a photographed image so as to heighten awake degree estimating accuracy by actuating an alarm at the time of judging lowering of an awake degree, setting a reference coordinate position and the deviation allowable value, and adjusting the focal length of a zoom lens. SOLUTION: An image filter extracts eyes accurately from an image of a CCD camera 2 and makes the output image binary. A doze detecting part 13 detects a wink from the inclination change of the corner of the eye on the basis of the binary image and judges lowering of an awake degree. An alarm part 15 actuates an alarm 3 in a cabin when the lowering of the awake degree is judged in the doze detecting part 14. In a bright state based on output data of an image processing part 13, the focal length of a zoom lens is adjusted so that deviation between the measured coordinate position of both eyes on the binary image and a reference coordinate position is within the allowable value. In a dark state, the coordinate position of both eyes on a retinal reflected image is measured, and the focal length is adjusted in the same way.

Abstract: PURPOSE:To discharge the high pressure of liquid from the back chamber of an actuator after high-pressure press work without causing an impact, noise or the like, effectively use the energy of the high-pressure liquid at the time of the pressure discharge and facilitate the adjustment of a pressure-discharging restrictor valve or the like. CONSTITUTION:In a pressure discharge process, the solenoid 43 of a valve 7 does not act and the valve functions as a conventional check valve but the solenoid 44 of a changeover valve 4 acts to shift it to supply pressurized liquid to the external pilot port 34 of a sequence valve 5. At that time, a restrictor valve 15 acts to gradually supply the pressurized liquid to the external pilot port 34 and the sequence valve 5 is gradually opened to the full degree so that pressurized liquid returned from a cylinder 2 and that supplied from a high pressure source 16 are charged into an accumulator 1. Since some amount of pressurized liqid is previously charged in the accumulator 1, the impulsive or noisy sound in the release of high-pressure liquid from the back chamber of the cylinder 2 into the accumulator is reduced.
