That is, it is necessary that not only a certain degree of positive chromatic aberration CLA on the axis is generated by a conversion lens and an Abbe's number V1 of the front group is made larger for the purpose of satisfactorily correcting various other aberrations to correct the chromatic aberrations. Though it is necessary that the front group consists of plural lenses including a cemented lens for the purpose of making this Abbe's number V1 larger, it is necessary that the Abbe's number vp of the positive lens in the front group satisfies the condition vp >=73 for the purpose of constituting the front group of one lens.

Title: Switch circuit
Inventor: TSUCHIYA TOMOTOSHI
IPC: H03K17/78
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To provide a high efficiency isolation switch circuit by adding a time constant imparting means to the input circuit of a pair of photocouplers to give a time constant to the transient change when the level of an input signal is alternated. SOLUTION: A switching transistor 300 is driven via photocouplers 400 and 500. The input signals are applied to LEDs 420 and 520 of the respective photocouplers 400 and 500 with polarities opposite to each other. Thus, one of both phototransistors 440 and 540 is turned on when the other is turned off. A capacitor 900 serving as a time constant imparting means is connected between the input signal supply lines of photocouplers 400 and 500. Thus, the capacitor 900 imparts a time constant to the transient change caused when the levels of the input signals of both photocouplers 400 and 500 are alternated with each other and accordingly the time when the output elements of photocouplers 400 and 500 are turned on is delayed. As a result, a period when both output elements are simultaneously turned on can be eliminated.

Abstract: PURPOSE:To detect a reflected light level from an object under a high S/N ratio and to improve focusing accuracy by selectively outputting a larger output out of outputs of two photodetecting elements to control the gain of an adjusting circuit. CONSTITUTION:When a light beam projected from a light projecting means 11 is reflected by an object 10 and made incident on photodetecting parts 12a, 12b of a photodetecting means 12, an automatic focus adjusting signal is detected from the adjusting circuit 13 by an output signal based on a difference between incident light values. Said signal is used for power supply etc. to a lens driving motor for driving a photographing lens to a focusing position. When a larger output out of the output signals of the photodetecting parts 12a, 12b is detected by a priority detecting circuit 14 and led into a gain adjusting circuit 15, the gain of the circuit 13 is adjusted by the output of the circuit 15. Even when the object 10 is located on a far position and the incident light of the reflected beams is low, only the larger output signal out of the outputs of the photodetecting parts 12a, 12b is selected and the gain is adjusted on the basis of the output signal having a high S/N ratio.
