Abstract: PURPOSE:To prevent a casing from falling down when a plurality of chassissis are drawn out. CONSTITUTION:A casing side clamper 10 fixed on the inner surface of a casing is formed so as to be able to freely rotate around a shaft 13 as the center. The shaft 13 is provided with a spring 14, by which the clamper 10 is always energized in the opening direction. Protruding parts 15, 16 are formed at the upper part and the lower part of the clamper 10. Chassis side clampers 20, 25 fixed on the side surfaces of the chassis side are formed so as to have nearly U-shaped sections, and square holes 21, 26 are formed at the nearly central parts. When two chassis side are drawn out at the same time, or when one chassis is drawn out in the state that the other chassis has been drawn out, either one of the protruding parts 15 and 16 engages with square holes 21, 26, and the chassis are prevented from moving.

Abstract: PURPOSE:To reduce the polling time by allowing each slave equipment to send reply information while shifting the time. CONSTITUTION:A carrier signal modulated by a reply request signal is inputted form a master equipment and a demodulated reception data is inputted to a control section, then an oscillator 21 is synchronized with a demodulation signal, a carrier-on signal is sent to a switch circuit 22 at a reply start time decided in a slave equipment to close the switch circuit 22 thereby sending the output signal of the oscillator 21 to a modulator 23. Since the transmission data modulates the output signal of the oscillator 21 and outputs the result to a lighting line, a reply request signal is sent to each slave equipment simultaneously in common to allow each slave equipment to make the preparation for the reply.

Abstract: PROBLEM TO BE SOLVED: To obtain a superior optical performance by minimizing an eccentric aberration, against a specific group whose error sensitivity of the eccentric aberration is relatively large in the ordinary design, and thereby reducing error sensitivity of the eccentric aberration of a specific group. SOLUTION: Tertiary aberration coefficients corresponding to coma- aberration, astigmatism and Petzval's sum are taken as II, III and P; a group, which is relatively large in the error sensitivity of nonuniform blurred aberration against parallel eccentricity and which is constituted of lens faces from i-th to j-th from the object side, is set as a specific group; and a group on the image side from it is considered to be an image side group. In this case, the absolute value is minimized for the value which is expressed by the equation of the specific group, namely, (α'j-αi).[3.(III)R+(P)R]-αi.[3.(III)D+(P) D]--(α"#j-α#i).[3.(II)R]+α#i.[3.(II)D].  Provided that () D and () R are each sum of the tertiary aberration coefficients of the specific group and the image side group, and that the initial value of the calculation of these coefficients is α 1=0, h1=1, α#1=-1, and h#1=-t.

Filed: 1985-08-23
Abstract: PURPOSE:To realize omission and simplification of a back-up circuit and to prevent initialization of respective parts by checking the contents of the memory at the time of instantaneous power failure recovering. CONSTITUTION:When an instantaneous power failure occurs, the specified value of the commercial alternating current is reduced from 100V to 0V, at once, the value returns to 100V usually, and at such a time, a direct current voltage V5 is a time constant of an electric power source circuit 33, and therefore, the voltage is reduced from the specified value of 5V and many times, the voltage returns to 5V before it is reduced to 0V.
