摘要:
The present invention provides a biological treatment method of biologically treating the subject water containing phenol, thiocyanate and the like, which improves the quality of treated water, while suppressing a reduction in treatment efficiency. As a means for achieving the aforementioned object, the present invention relates to a biological treatment method including introducing subject water containing a COD component, wherein the COD component is at least one of phenol and thiocyanate, into a biological treatment tank containing sludge containing bacteria capable of decomposing the COD component to thereby biologically treat the COD component with the bacteria, wherein, before the introduction of the subject water into the biological treatment tank, a step of counting the total number of bacteria contained in the sludge is carried out, so that the amount of the COD component loaded on a single bacterium per unit time can be controlled within a predetermined range.

A photoelectric sensor device has a two-dimensional arrangement of a multiplicity of unit structures each including a pixel. The sensor device includes a circuit for simultaneously designating a plurality of pixel blocks of any desired sizes at any desired positions on the two dimensional arrangement of unit structures, each pixel block being composed of pixels which are to be actually used. The sensor device also includes a monitor output circuit for outputting, for each of the pixel blocks, at least one monitor output as the representative of the amounts of charges accumulated in the pixels in each of the pixel blocks. The sensor device further includes a circuit which executes the control of accumulation of charges and the control of outputting of the image signals on each of the pixel blocks independently of other pixel blocks. Disclosed also is a focus detection system using the sensor device.
摘要:
A focus detection apparatus for a camera in which a plurality of focus sensors detect the focus states of a plurality of different areas within the scene. A processor determines whether the focus can or cannot be obtained to a specific area of the scene on the basis of the outputs of the focus sensors. An auxiliary light is emitted to assist in focusing, if the specific one of the different areas is, for example, the central area.

摘要:
A color proof formation method includes the steps of bringing a first color separated film original mounted upon an original mounting table into tight contact with a photosensitive material fixed upon a mounting table, and exposing the film original; separating the photosensitive material mounting table from the original mounting table; replacing or exchanging the first film original upon the original mounting table with a second color separated film original; and bringing the second film original into tight contact with the photosensitive material. The steps are repeatedly performed a predetermined number of times so as to form a color proof. There is also disclosed a color proof formation apparatus including a suction unit for forming a suction groove, for bringing the film original and the photosensitive material into tight engagement with each orther, between the film original mounting table and the photosensitive material mounting table while the film original mounting table and the photosensitive material mounting table are close to or in contact with each so that the film original and the photosensitive material are brought into surface contact with each other, and for evacuating the air interposed between the film original and the photosensitive material so that the film original and the photosensitive material are in fact brought into tight contact with each other.

The disclosed automatic focusing device measures distances by repeatly illuminating an object to the photographed with an auxiliary light. Upon detection of an in-focus state, either the auxiliary light illumination is inhibited or the auxiliary light driving cycle is made longer than the cycle used in a de-focus condition, so that the waste of electric energy is minimized.
摘要:
Disclosed is an automatic focusing apparatus for a camera and, more particularly, to an automatic focusing apparatus for a camera of a type which performs a focus detecting operation under emission of auxiliary light when, e.g., luminance is low. In the camera of this type, if a mode of the automatic focusing apparatus is set to a servo mode, the servo mode can be switched to a one-shot mode when the focus detecting operation is to be performed under emission of the auxiliary light. Since the auxiliary light is not continuously emitted, an auxiliary light source is protected.
