A sunshade for a vehicle sunroof is structured to have a base member for shielding sunlight from striking the inside of the vehicle through an opening formed in the vehicle body when the sunshade is closed, which is housed within a housing space formed adjacent to the opening when the sunshade is opened, and an edge member integrally provided with a handle, which has a shield integrally mounted on the advancing-side end portion of the base member to shield the advancing-side terminal portion from the view of the vehicle occupant. This construction of the sunshade improves the productivity and reduces the cost of the sunshade.

A divider which multiplies both divisor and dividend by a first multiplier generated from the divisor to compute an intermediate divisor and an intermediate quotient, and iterates such computations by the number of times needed, so that the intermediate divisor approaches a predetermined value, and the intermediate quotient approaches the quotient obtained by dividing the dividend by the divisor. This makes it possible to implement a fast divider with a configuration simpler than that of a conventional divider which feeds back the outputs of multipliers many times depending on the accuracy required, which involves delay times in the multiplication and makes the configuration complicated.

An apparatus for waste water treatment, wherein fluorine contained in waste water is treated into a fluoride through a chemical reaction and sludge containing the fluoride is thickened and dehydrated into a sludge cake, has first and second tanks each packed with calcium carbonate mineral. In the first tank, waster water containing fluorine is agitated by air discharged from an air diffuser and caused to react with the calcium carbonate mineral. Through this reaction of the waste water with the calcium carbonate mineral and action of microorganisms on the surface of the calcium carbonate mineral, a pH value and a fluorine concentration of the waste water is adjusted till the pH value and the fluorine concentration fall within their respective predetermined ranges. In the second tank, an aluminum agent is added to the waste water coming from the first tank while the waste water being agitated so that the pH value and the fluorine concentration of the waste water are further adjusted through a chemical reaction of the fluorine with the calcium carbonate mineral and aluminum agent and action of microorganisms propagating on the surface of the mineral so as to fall within their respective target ranges.

A sign inverting Booth encoder included in an encoding circuit generates a control signal designating a partial product having a sign different from that designated by an output signal generated from a conventional Booth encoder. A partial product generating circuit generates a partial product according to the control signal from the encoding circuit. A partial product having a sign inverted or non-inverted is generated from a shifter/inverter circuit. A converting circuit generates three-value redundant binary numbers using a sign inverted partial product and a sign non-inverted partial product as a set. An intermediate sum generating circuit performs a redundant binary addition of the three-value redundant binary numbers to generate a final redundant binary number. A final adding circuit converts the finally generated three-value redundant binary number into an ordinary binary number to generate a product Z of binary numbers X and Y. As a result, a multiplier performing multiplication at a high speed with a smaller number of elements is implemented.

An electric motor, in which the thrust bearing action is performed by the magnetic attraction forces induced between a annular stator core with toroidal coils and magnets confronting the stator core, includes at least a cup-shaped member with a central cylindrical portion opened at the center, the cup-shaped member serving as a magnet yoke and a seat on which an element to be driven by the motor is mounted, and a cylindrical rotary sleeve press-fitted in the central cylindrical portion. This construction contributes to a reduction of the weight, size and manufacturing cost of the motor.

In an automatic focusing apparatus which detects sharpness signals from high-frequency components of brightness signals contained in video signals from video cameras and which stops a focusing lens of the video camera at a position at which its peak value is obtained, the movement of the focusing lens is started by detecting received light signal levels by performing projection-reception operations with a specified amount of infrared light and detecting their variations with a received light signal level detector or with a micro-computer. Furthermore, depending upon the focal depth of the focusing lens, priority is given to processing of distance information based on sharpness signals or distance information determined by the infrared light projection-reception operation in the lens driving controller for performing the focusing operation. According to the automatic focusing apparatus of the present invention, movement of the lens only due to variations of contrasts can be avoided, and stable image pictures are thus obtainable. Also, the most suitable focusing operation mode for a particular focal depth of a lens in use can be selected.
