Title: System and device for optical recording/reproducing
Inventor: CHATANI MASAHIKO
IPC: G11B7/085
Filed: 1988-04-26
Abstract: PURPOSE:To improve the transfer speed of recording/reproducing and to facilitate the tracking servo at the time of reproducing by making a laser beam incident upon an acoustic optical deflection element for main scanning after being inputted to an acoustic optical deflection element for subscanning. CONSTITUTION:An output of a semiconductor laser 10 is interrupted by a modulation signal 32 to be incident upon the acoustic optical deflection element 14 via a collimator 12. Its deflection angle is changed by an ultrasonic signal Sy and it is swept by a period Ty in the direction of Y. Then, it is made incident via an optical element 15 upon the acoustic optical deflection element 16 and swept by an ultrasonic signal Sx in the direction of X with a period Tx (Tx>Ty). Consequently, a collective track 21A(Z) of plural subtracts Xs is formed one by one on a recording medium 21 in the traveling direction. A sweep signal among the elements 14 and 16 is selected, and a feed speed is decided so that the period Tx is conformed with a period of a CTL signal 21B of the medium 21. By this constitution, one main track can be recorded with a large quantity of information and reproduced, improving the transfer speed, and a servo mechanism can be simplified by way of giving a tracking control signal to the subscanning element 14.

Title: Waveguide-type liquid detecting sensor
Inventor: INUZUKA HIROMASA
IPC: G01N21/41
Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To obtain a waveguide-type liquid detection sensor which prevents a characteristic from being changed due to an error in an angle, which eliminates a need of a high-accuracy alignment operation and by which a liquid can be detected optically by a method wherein light is incident on an optical waveguide on a substrate and a quantity of reflected light from an exposed part at the end part of the waveguide is detected. SOLUTION: A layer is formed on the surface of a substrate 11 so as to be used as an optical waveguide 12, and a step (a discontinuous face 15) is formed on its surface. The discontinuous face 15 is used as an exposed part. When a slope is worked, the surface of the substrate is used as a reference. The cause of an error in a characteristic is decided by the working accuracy in the formation of the slope, and a high-accuracy alignment operation is not required. In addition, only when a diffraction grating on the surface of the substrate is used as a light input mechanism 13 so as to work the surface of the substrate, an element can be formed, and a single-wafer treatment which is suitable for mass production can be executed.  Thereby, a sensor 1 can be formed by a simple process which is suitable for mass production, in which the surface of the substrate is worked and in which a film is worked. In addition, since the diffraction grating is used as the light input mechanism, a plurality of sensors can be driven simultaneously, and a liquid such as an oil leaked from a petroleum plant whose explosionproofness is required can be detected.
