摘要： Changes in states giving rise to electrode breakage and ball formation are made less likely during firing step for sintering the laminated body, and the improvement in DC bias characteristics is achieved in laminated ceramic electronic components with a laminated body which has internal electrodes, even when ceramic layers and the internal electrodes are reduced in thickness. The laminated body is divided into a large grain region in which the ceramic has a relatively large grain diameter and a small grain region in which the ceramic has a relatively small grain diameter. The large grain region is located outside the small grain region, and a boundary surface between the large grain region and the small grain region is located inside the outer surface of the laminated body while surrounding a section in which the internal electrodes are present in the laminated body. In order to obtain the laminated body, a heat treatment is carried out in the firing step with a temperature profile in which the average rate of temperature increase from room temperature to the maximum temperature is 40° C./second or more.

摘要： The present invention relates to an optical camera having a zoom function in which a focal length can be varied or the variation is actuated by a focal length changing member, and in particular to a camera in which a focal length is varied through a motor. The optical camera has a zoom lens operable by a rotatable zoom ring for changing the focal length thereof. An automatic focusing operation is effected by a control means when the focal length is changed so that an image of an object viewed through a viewfinder remains in focus. The zoom lens can include a motor and an in-exposure zoom control means can be provided for controlling zooming movement of the lens during an exposure operation.

摘要： An information setting and displaying device for a camera, has a ring-like rotary dial rotatably mounted in an adjustable manner on a camera body. A display member includes at least a pair of display sub-areas arranged inside the rotary dial and successively along an inner periphery of the rotary dial. An information setting mechanism changes information in a predetermined order responsive to rotation of the dial. A display control mechanism displays current set information in one of the display sub-areas, and displays proposed information, to be set as the rotary dial rotates, in the direction from the current display sub-area toward another display sub-area.
