An imaging apparatus includes an image optical pick-up device, first and second driving mechanisms, a shutter, and a driving current controlling mechanism. The image optical pick-up device photoelectrically converts an incident light image of a subject of a photograph. The first driving mechanism drives the image optical pick-up device and performs a rapid sweep function for rapidly draining unnecessary electric charges remaining in the image optical pick-up device. The shutter opens and closes a light passage for passing the incident light image into the image optical pick-up device. The second driving mechanism generates pulses to drive the shutter. The driving current controlling mechanism performs a control such that a first duration in which the first driving mechanism operates the rapid sweep function and as second duration in which the second driving mechanism generates a pulse for closing the shutter do not overlap under predetermined imaging environmental conditions.

An oil filter for preliminarily confirming a correct assembling of a valve body to a holder and for preventing the valve body from being abnormally assembled. A valve seat 22 is welded to a cap 14 covering a filter element 12. A claw portion for a valve body 25e is formed on the valve body 25, and an engagement portion for the valve body 27e to be engaged with the claw portion for the valve body 25e is formed on a holder 15 assembled with the inner peripheral side of the filter element 12. In addition, a spring member 29 is fitted between the valve body 25 and a spring receiving portion 27 provided for the holder 15. By the engagement of the claw portion for the valve body 25e with the engagement portion for the valve body 27e, the valve body 25 is assembled with the holder 15.
摘要:
In a terminal member, a protuberance is formed so as to protrude toward an external electrode, and thereby, a bonding portion where the terminal member is bonded to the external electrode, the bonding portion being formed with solder, is extended substantially linearly across a part of the external electrode. Preferably, the direction in which the bonding portion is elongated linearly is in parallel to that in which internal electrodes are extended. Further, it is preferable that the bonding portion is as wide as possible, and the center of the bonding portion in the width direction is as near to the center of the end-face of the capacitor body as possible.

A method of manufacturing a ceramic electronic part having a desired film thickness and external electrodes such that the part is manufactured without projections and depression of the surface thereof, includes applying an electrode paste of a prescribed thickness on the surface of the ceramic element. The electrode paste is applied by rotating a roller with the electrode paste on its peripheral surface, and by moving at least either one of the roller and the ceramic element in a prescribed direction so that the ceramic element moves relative to and tangentially of the roller in the direction opposite to the rotation of the roller with at least a part of the ceramic element dipped in the electrode paste applied on the peripheral surface of the roller.

A ceramic electronic component satisfies a condition expressed by H1≧0.03L, wherein H1is the distance between the surface of a substrate on which the ceramic electronic component is mounted and a point P at which outer terminals connecting the ceramic electronic component to the substrate first contacts the side surfaces of the ceramic electronic component and L is the length of the ceramic electronic component. The ceramic electronic component also satisfies a condition expressed by H2≧2t wherein H2is the distance from a lower surface of the ceramic electronic element 4 to the surface of the substrate 7 and t is the thickness of the outer terminals.
