Title: Correcting method of spherical aberration
Inventor: NAKAYAMA HIROKI
IPC: G02B9/12
Filed: 1984-02-03
Abstract: PURPOSE:To correct satisfactorily a spherical aberration by sticking a refractive index distribution type line whose refractive index is varied in the radial direction, and a lens consisting of a homogeneous medium, and equalizing refractive indexes of both the lenses at a prescribed position in the effective diameter of the lens. CONSTITUTION:A cemented lens consists of a refractive index distribution type lens 2 having such a variation as the refractive index drops gradually in the radial direction centering around the optical axis, and a lens 1 consisting of a homogeneous medium. As for these two lenses 1, 2, a difference of the refractive indexes scarcely exists in the vicinity A of the optical axis, therefore, a refraction of light does not occur, but at a point B separated from the optical axis, a refraction occurs due to a difference of the refractive indexes. As a result, on the cemented surface, in the point separated from the optical axis, a refractive index of a luminous flux becomes large. Accordingly, an out-of-axis luminous flux in each image height can be led in a desired direction, and a spherical aberration can be corrected satisfactorily by only one lens.

Filed: 1980-02-19
Abstract: PURPOSE:To halve the effect of an error, by providing a speed servo means detecting the moving speed of head and feeding back the deviation from an objective  speed from an objective speed generating means to a drive source. CONSTITUTION:A high speed objective speed signal VH is produced from a constant voltage source 60 and the objective low speed signal VL is produced by dividing it with resistors R1, R2. First, the switching circuit 70 selects the high objective speed signal VH and adds it to the differential circuit 50. Actual mobile speed signal of the head is fed to another input of the circuit 50. This mobile speed signal is formed at an addition circuit 90 by adding a voltage fed to the drive device 40 added with the output of the differential circuit 50 via the correction value pickup circuit 80. By producing the difference between this voltage and the voltage of the drive device 40 at the addition circuit 90, speed electromotive force, i.e., speed signal is obtained.

Abstract: PURPOSE:To measure the real moving quantity in a high temperature state within a reduced period of time by subtracting the thermal expansion generated during the measuring time from the measured displacement making use of the fact that the thermal expansion of an article to be measured at a high temperature can be approximated by a linear expression with the time as variable. CONSTITUTION:After an article 1 to be measured is heated to a prescribed temperature by an external temperature adjusting device 2, the displacement of the article 1 to be measured is measured during prescribed period of time t1 by a displacement meter 4, and the measurement H and the measuring time t1 are stored in an operating means 5, i.e., stored as the thermal expansion of the article 1 to be measured H=alpha.t1 (where, alphais a constant and the ratio of time change of the thermal expansion). Then, while the movement quantity (displacement) of the article 1 is measured, the force is applied to the article by a moving means to move the article during the prescribed period of time t2, and the displacement H' is outputted to the operating means 5. The operating means 5 substrates the total thermal expansion S, {S=alpha.(t1+t2)} from the raw data H' of measurement to obtain the true movement quantity L and realize the display 6. This constitution reduces the waiting time until the thermal expansion of each component is settled.
