Title: Inclinometer of photoelectric bubble tube type
Inventor: SUGAWARA SABUROU
IPC: G01C9/06
Filed: 1984-05-30
Abstract: PURPOSE:To measure inclinations of two orthogonal components simultaneously with a high sensitivity in a small-sized constitution by putting a bubble in a glass cylinder and irradiating a parallel luminous flux to the bubble and detecting a shadow due to the bubble by a photoelectric element. CONSTITUTION:A parallel transparent glass 4 is provided in one end of a glass cylinder 2, and a concave disc 3 is provided in the other end, and an alcohol is filled up in the cylinder 2, and a bubble 5 is put in the cylinder 2. The parallel luminous flux is made incident on the cylinder 2 from a light source 9 through a convex lens 8 to irradiate the bubble 5. Then, the illuminance is lower than a half of the illuminance of the external because the bubble 5 has the function of a convex lens, and the shadow is vivid because the light is to totally reflected on the side face of the bubble in the outside edge part of the bubble 5. The light emitted from the cylinder 2 is received by a photoelectric element 10 to detect the image of the bubble 5, and the inclination is measured in accordance with positions in X-axis and Y-axis directions. Consequently, the inclination is detected with a high sensitivity because the parallel luminous flux is irradiated to the bubble to form a vivid bubble image.

Title: Focus servo mechanism of optical head
Inventor: ICHIHARA JIYUNICHI
IPC: G11B7/09
Filed: 1982-06-25
Abstract: PURPOSE:To obtain an optical head of a compact and lightweight structure, by driving a cylindrical permanent magnet provided with an objective lens at its center inside by a magnetic field produced with electric conduction of a solenoid and cntrolling said lens so as to ensure a focus on the optical disk at all times. CONSTITUTION:An objective lens 6 is fixed at the inside of a cylindrical permanent magnet 5. A bobbin 7 is provided with two solenoids 8 and 9 to generate magnetic fields which are opposite to each other with an equal size with electric conduction of those solenoids. The magnet 5 is supported by a diaphragm 10 so that it can have a slight movement to the bobbin 7. Thus the magnet 5 moves up and down in proportion to the level of the current supplied from a power supply and in response to the direction of current. This provision enables focusing as well as a compact and lightweight structure that is so far impossible owing to the iron core of a VCM used in a conventional focus control mechanism. As a result, high-speed access is possible for an optical head.

Abstract: PURPOSE:To ensure the reliability of the display of the allowance of the amount of light by inhibiting the reset of a display state until the next period for judging the presence or absence of a body by an allowance-display setting circuit when the display state is set at the allowance state of the amount of the light during one period for judging the presence or absence of the body. CONSTITUTION:A body-presence judging circuit 6 judges the presence or absence of a body when reflected light R from an object X is higher than the lowest amount of light. An allowance judging circuit 7a judges the fact that there is allowance or there is no allowance, when the judged results as to whether the reflected light R exceeds the amount of the allowance light larger than the lowest amount of the light or not are equal by the specified number of times. An allowance-display setting circuit 7b sets the allowance display based on the result of the judgment of the circuit 6 and the result of the judgment of the circuit 7a. In the circuit 7b, the reset of the display state is inhibited until the next period for judging the presence or absence of the body, when the display state with a display means 9 is set in the allowance state of the amount of the light during one period for judging the presence or absence of the body. Therefore, the sufficient reliability and the stabilized display state are obtained in the judgment of the allowance.
