Abstract: PURPOSE:To make a construction and assembling simple and to make a focusing operation easy by forming a lens composing a main optical system and a deflecting optical part composing a sub-optical system in a body with a plastic and equalizing a focus distance of both optical systems. CONSTITUTION:In a compound lens 3, a surface 3b of a sub-optical system is eccentric in one direction outside a main optical system 3 and formed in a single body.

The sub=spot S5 is reflected from the surface D, the surface 3a of the main optical system is transmitted, and thereafter, the spot is reflected by a beam splitter 2, and converted S5 to the second light detecting device 5. The second light detects a focus error and automatically focused. Incident light from the main optical system 3a is collected as the main spot S4 on the surface D, and the reflecting light is converged S4 to the first light detecting device 4 and the information is read. The focus distance of the main optical system and the sub-optical system is equalized. Thus, the construction and assembling go to be simple and a focus operation is made easy.

IPC: F02D41/04
Filed: 1999-08-30
Abstract: PROBLEM TO BE SOLVED: To reduce adsorbed fuel in a canister efficiently without instabilizing the combustion of a lean operation in a lean burn engine.

Title: Still picture display device
Inventor: SATO HITOSHI
IPC: H04N7/15
Filed: 1988-09-28
Abstract: PURPOSE:To display and store the succeeding still picture by switch start by inputting an input picture signal to a still picture memory and a still picture monitor when an input/output switch is turned on, avoiding the input to the still picture memory when the switch is turned off and sending a readout output to the still picture monitor instead. CONSTITUTION:A timing pulse generated in a timing generating section 7 is a switching pulse for switches 81, 82. With an input switch 81 thrown to the position of a terminal (a), an input picture is stored in a memory 1. In this case, since an output switch 82 is also thrown to the position of the terminal (a), the output picture is the input picture itself while being bypassed through the memory 1. When an input picture (2) is written in the memory 1, a still picture monitor 2 displays the picture (2) as a moving picture. However, it is limited to one pattern and since the switches 81, 82 are both thrown to the position of a terminal (b) in the next input picture (3), the output picture is a still picture (2) read from the memory 1 and it is outputted repetitively. Thus, one pattern just after the memory switch operation is stored in the memory and displayed in the still picture monitor.
