    摘要: This prevents biting and miniaturizes an entire mechanism. There is provided a lens driver including: a driver having a frame that holds a lens and a bearing for receiving a guiding axis to move the lens in an optical axis direction, a lead screw in which a screw to which a nut is screwed is formed, and a stepping motor for rotating the lead screw; an arm extended from the frame, in such a way a tip being next to the nut, and moving the frame by movement of the nut; a spring for pushing an arm tip towards the nut; and an idle rotation section placed on only side where the arm is placed for the nut at a lead screw end of the driver, and has an axis diameter disabling the nut to be screwed. Also there is provided an image capture apparatus having the lens driver.

    摘要: A zoom lens barrel includes a front lens holder frame with a male helicoid and a rear lens holder frame including a cam follower pin. A linear movement guide mechanism guides the front and rear lens holder frames to move in the optical axis direction. A rotatable drive ring, with a female helicoid, engages with the male helicoid of the front lens holder frame and with a cam groove in which the cam follower pin of the rear lens holder frame is fitted. The cam groove is provided with a plurality of spaced back focal distance adjusting sections parallel with the lead of the helicoids and with a plurality of zoom sections that connect the adjacent ones of the spaced back focal distance adjusting sections and that are not parallel with the lead of the helicoids. The drive ring is always stopped when the cam follower pin is located in any one of the back focal distance adjusting sections.

    摘要: A zoom lens barrel has a rotatable cam ring which is provided on an inner peripheral surface thereof with a female helicoid which can be engaged by a male helicoid formed on an outer peripheral surface of a lens support and a cam groove in which a cam follower pin formed on a lens frame can be fitted. At least a part of said cam groove penetrates in an area of said female helicoid in the axial direction of said cam ring. The cam ring is provided with a first area in which the female helicoid is formed and a second area separate from the first area, in which the cam groove is formed, so that the cam groove does not interfere with the female helicoid.

    摘要: Apparatus for treating exhaust gases comprising a catalyst bed through which the exhaust gas is passed whereby nitrogen oxides and dust present therein are removed from the gas, said catalyst bed being designed such that the catalyst therein is discharged from the bed continuously or intermittantly while being fed in an amount that can compensate for the discharged amount, a heating device for heating the catalyst discharged from the bed to a temperature in a range from about 700.degree. to 1200.degree. C. for reactivation of the catalyst and separation of the dust accumulated on the bed surface and retained in the interstices between the catalyst particles therein, and a device for discharging sulfur dioxides produced during the course of heating the catalyst. This apparatus is very effective in simultaneously removing the nitrogen oxides and the dust from exhaust gases such as boiler exhaust gases.

    摘要: A method for removing sulfur dioxide from waste gases by a wet oxidation-absorption method, which is characterized in that an aqueous solution of ammonium sulfate acidified with sulfuric acid at a pH range of 3 - 4 is used as the absorbent. The SO.sub.2 contained in the waste gases is absorbed with the aqueous solution of ammonium sulfate in an absorption tower and then oxidized with air or oxygen to be converted into sulfuric acid in an oxidation tower.
