Abstract: PURPOSE:To obtain the ftheta lens which is small in thickness and is constituted of one element by forming the curved surface within the main scanning plane of the lens face on a deflecting point side to an aspherical face shape which projects toward the deflecting point side particularly near the optical axis and further specifying the shape within the main scanning plane of this face. CONSTITUTION:The curved surface within main scanning plane of the lens face on the deflecting point side of the deflecting face is formed to the aspherical face shape which projects toward the deflecting point side particularly near the optical axis. The radius of curvature near this optical axis, designated as r1 and focal distance near the optical axis within the main plane, designated as fm, have the relation of equation I. The face shape within the main plane is expressed by a function S1(y) with the coordinate system having the origin at the intersected point of the lens face on the deflecting face side and the optical axis, the (x) axis in the optical axis direction and the (y) axis within the main plane. When the max. effective diameter within the main plane of this face is designated as Ymax, S1(y) is defined between O and Ymax and is so determined as to satisfy equation II when r1<Ymax and equation III when r1>=Ymax, respectively. The ftheta lens which is reduced in the thickness of the lens and is constituted of one element is obtd. in this way.

Title: Loop control system
Inventor: YANAGIDA IKUO
Filed: 1987-06-26
Abstract: PURPOSE:To prevent a control circuit of a controlled station from entering an infinite closed loop due to mis-control by initializing periodically a control signal controlling a loop by a master station. CONSTITUTION:A master station initializes an output of a gate circuit 2 periodically at a period T1 generated from a period generating circuit 1 to output the output to a low-order station as a transmission control signal S2. On the other hand, a slave station to be controlled passes a received control signal S3 from a high-order station as it is and outputs it to a low-order station as a transmission control signal S4 and outputs a signal S5 to apply the control of an internal circuit actually from a storage circuit 3 to an internal control circuit. Thus, even if a control bit is in error and the slave station to be controlled enters an infinite loop, the station is restored normally.
