摘要:
An evaporative fuel discharge-preventing device for an engine which comprises a surge tank for leveling out fluctuations in the amount of evaporated fuel so as to provide a stabilized engine rotational speed, and to prevent the impairment of drivability. The surge tank has outlet and inlet side pipes arranged at a height position to avoid storing the evaporated fuel in a liquid state within the surge tank. The surge tank, having a predetermined volumetric capacity, is disposed midway of an air communication passage between an intake manifold and a purge valve, and is located at a height position greater than the intake manifold.

In order to effect an automatic focus control in an image pick-up apparatus, a photography lens for forming an image of the object onto a two-dimensional solid state image sensing device is arranged in a fixed position, while the two-dimensional solid state image sensing device is arranged movably in the optical axis direction of the photography lens, and the image sensing device is moved in accordance with a focusing error signal detected by a focusing condition detecting circuit having an additional light receiving element mounted on the same substrate as the image sensor but discrete from and operating independently of the image sensor. Since the light and small solid state image sensing device is moved for the focus control instead of the heavy and large photography lens, it is possible to perform the focus control in a prompt manner and to make a mechanism for driving the image sensing device small and simple.

An apparatus for detecting a focus condition of an imaging lens of a still camera by detecting a lateral shift of two images formed on a light receiving element array by means of light fluxes transmitted through different sections of the exit pupil of the imaging lens divided by a stripe mask is disclosed. The variation of outputs from light receiving elements of the array due to an image height is corrected electrically by means of a correction circuit including first and second triangular wave generating circuits for generating first and second triangular waves having negative and positive inclinations, a clock pulse generator for producing clock pulses, a signal selection circuit for selecting alternately the first and second triangular waves in synchronism with the clock pulses to produce a correction signal, and a multiplying circuit for multiplying the outputs from the light receiving elements with the correction signal to provide a corrected signal from which the lateral shift can be detected accurately.
