Abstract: PURPOSE:To obtain a semiconductor device having a capacity element causing a little leak current by a method wherein the surface of a polysilicon film being a lower electrode of a capacity element part is nitrided by RTN treatment, a tantalum oxide film is formed thereafter and further a titanium/tungsten nitride film is formed as an upper electrode. CONSTITUTION:An element isolating oxide film 2 is formed on an N-type silicon substrate 1 and a polysilicon film is deposited. Then, a lower electrode 3 is formed by doping this film with phosphorus and patterning it. After a natural oxide film located on the lower electrode 3 is removed, the surface is nitrided by a lamp annealing processing using an ammonia gas and thereby a silicon nitride film 4 is formed. A subsequent tantalum oxide film 5 is formed on a wafer by a chemical vapor phase reaction with organic tantalum pentaethoxide or the like used as a material gas. After the tantalum oxide film 5 is deposited, moreover, densifying treatment by high-temperature heat treatment is conducted. Subsequently, a titanium nitride film and a tungsten film are formed as an upper electrode 6.

Abstract: PURPOSE:To reduce the probability of occurrence of rumples so as to obtain excellent picture qualities stably by pressing a photosensitive member, transfer member, or both of the sensitive and transfer members against one pressure developing roller by means of the pressing section of pressure developing rollers. CONSTITUTION:When it is detected that a photosensitive member 17 and transfer member 18 are inserted into the space between an upper and intermediate pressing rollers 6a and 6b, a cam shaft 6q which fixes a cam 6d and pushing roller cam 6g rotates.

Abstract: PURPOSE:To reduce manual work by using as an area to be devided a rectangle which is an enlargement of a rectangular region in similar form such that four coordinates indicating the rectangular region circumscribing an illuminance measuring region are each an integer multiple of the length of the interval between dividing lines. CONSTITUTION:A calculating portion for a rectangular region 4 calculates the region 4 circumscribing an illuminance measuring region 1, e.g. a baseball field, by using data about the form of the illuminance measuring region 1 which are stored in a storage portion. A calculating portion for a region 5 to be divided calculates the region 5 which is an enlargement of the area 4 in similar form such that four (x, y) coordinate values indicating the region 4 are each an integer multiple of the length of the interval between dividing lines 2. An identifying portion for illuminance measuring points 8 divides the region 5 using a plurality of orthogonally intersecting lines 2 and, with the points of intersection of the lines 2 proposed as points 6 at which to measure illuminance, it identifies the points 6 as measuring points 8 when a line connecting the points 6 to, e.g. the home plate 3a does not intersect the boundary of the region 1 or when the line intersects the boundary by an even number of times. All the measuring points 8 are thus calculated and the result of this calculation is output to a display portion.

Abstract: PURPOSE:To prevent cloggings of a screen by installing an endless link chain including a dust collecting screen in such a manner that the lower end of said chain is directed to the upstream side of a water channel so as to be inclined to said channel and providing a pipe for discharging air bubbles below the screen. CONSTITUTION:A dust collecting device 100 is formed, wherein an endless link chain 3 provided with a screen frame 4 is driven through a pair of upper and lower sprocket wheels 1, 2. Next, the device 100 is disposed in a water channel in such a manner that it is inclined to the channel, with its lower end directed to the upstream side and the upper end to the downstream side of the channel. An air pipe 50 is provided along the underside of the frame 4 adjacent thereto and a plurality of air outlet ports are provided on said pipe except for a portion thereof near the surface of the water. The frame 4 is driven obliquely upwardly from the lower end to collect dust and discharge it to a trough 10. When a large amount of dust such as jellyfish has been generated and the entire area of the frame 4 has been covered therewith, air bubbles are delivered from the pipe 50 to separate the attached dust, causing it to float, collecting it by the frame 4. As a result, a water passage is ensured, thereby restraining differences of water levels between the front and rear sides of the device to enable safe operation.
