IPC: G03B9/02
Filed: 1997-08-12
Abstract: PROBLEM TO BE SOLVED: To reduce the number of parts and to miniaturize a lens barrel by rotatably holding a diaphragm interlocking member for operating a diaphragm unit at a holding part formed at the internal end face of a fixed member when a key member guiding a lens group by a straight advance key extended in an optical axis direction is fixed on the fixed member. SOLUTION: The straight advance key 3 is constituted of a mounting surface part 3a fixed on a mount 1 and a key part 3b extended in the optical axis direction, and the key part 3b is fit to be slidable in a straight advance groove 8b formed on a lens moving frame 8, so that an optical system is straight moved. After the diaphragm interlocking member 2 whose almost center part is made a plate-like annulus ring is rotatably fit in the mounting part 1a of the mount 1, the mounting surface part 3a is fixed, so that the movement of the member 2 in the optical axis direction is restricted. At the time of adjusting light quantity, the member 2 transmits the diaphragm operation from a camera main body side to a diaphragm unit 5 by an interlocking lever 2a. In such a case, the plate-like annulus ring of the member 2 smoothly slides and rotates around an optical axis in the mounting part 1a.

Title: J-k flip flop circuit
Inventor: SATO YASUSHI
IPC: H03K3/356
Filed: 1994-09-12
Abstract: PURPOSE: To make an integrated circuit low in cost by making output data a set or reset state when a J signal and a K signal are different and outputting the previous output data when the J signal and the K signal are the same. CONSTITUTION: When a J signal is an H level and a K signal is an L level, an N-MOS5 is turned on and a P-MOS2 is turned off. Because a node N3 is also an H when a node N1 is the H, an N-MOS6 is turned on. At this time, when an inversion clock signal BCP becomes the H, an N-MOS4 is also turned on and the node N1 changes from the H to an L. Next, when a clock CK rises to the H, the node N3 or an output terminal 17 becomes the L and an output terminal 16 becomes the H. Namely, an output signal Q becomes the H and an inversion output signal BQ becomes the L. The both of the J signal and K signal are the L, a clock signal CP becomes the H and the output signal Q maintains its previous state even if a clocked inverter 13 is activated.

Abstract: PURPOSE:To improve the insulating withstand voltage between the gate electrode and the wiring even though the film thickness of the insulating film between a pair of the conductor layers is thin by a method wherein the insulating film is formed of a silicon nitride film, a silicon oxide film and a silicate glass film. CONSTITUTION:A silicon nitride film 14 is made to grow in a thickness of 400Angstrom  or thereabouts, for example, as the first insulating film by an ordinary chemical vapor-phase growth method. Subsequently, a polycrystalline silicon film is made to grow in a thickness of 500Angstrom , for example, by an ordinary decompression chemical vapor-phase growth method, an oxidation is performed in an atmosphere of vapor for 50min at 900 deg.C, for example, and a silicon oxide film 15, which is the second insulating film, is formed. The film thickness of this silicon oxide film 15 becomes 1,000Angstrom  or thereabouts and is uniform despite the roughened surface. By this way, a failure of insulating withstand voltage between the conductor layers due to a decrease in the insulating film between the conductive layers, which is caused by the edge parts with such protruded parts as electrode and wiring and the reduction of the film thickness of the insulating film at the recessed part, is never generated and the improvement of the ratio of the non-deflective of semiconductor device to the defective thereof is brought. Then, a PSG film 16 is formed on the silicon oxide film 15 by a chemical vapor-phase growth method as the third insulating film.
