Title: Automatic focus controller
Inventor: OIKAWA MASARU
IPC: H04N5/232
Filed: 1998-11-16
Abstract: PROBLEM TO BE SOLVED: To attain a fast and highly accurate focus adjusting action by restoring an image against the image data obtained by performing the photographing by means of a restoring filter corresponding to an optional spot image radius to calculate the AF evaluation value and referring to this evaluation value for every driving of a focal lens to decide the final focus adjusting position. SOLUTION: This controller contains a lens system 1, a diaphragm 2, a CPU 6, etc. An image is restored against the image data obtained by performing the photographing at an initial focal lens position by means of plural restoring filters, the AF evaluation value is calculated about a restored image data group and a rough focus adjusting point is decided by referring to the AF evaluation value. Then an image is restored against the image data obtained by performing the photographing while a focal lens is moved from the rough focus adjusting position by means of a restoring filter corresponding to an optional spot image radius, the AF evaluation value is calculated and the final focus adjusting position is decided by referring to the AF evaluation value. The CPU 6 calculates the AF evaluation value and performs the one-shot AF control.

Title: Manufacture of cylinder coating body
Inventor: UMEHARA NORIJI
IPC: B05D3/00
Filed: 1992-12-04
Abstract: PURPOSE:To prevent the generation of coating defects by carrying out the gas reducing treatment in a manner that the base melting amount of coating fluid satisfies the given condition in a body forming a continuous film on the base end surface by moving a fluid discharge nozzle in the base axial direction while the cylindrical base is rotated. CONSTITUTION:In the manufacture of a cylindrical coating body such as an electronic photosensitive drum forming a coating film of an organic photoconductive material on the surface of the cylindrical base, coating fluid is discharged and applied helically on the surface of a base while rotating the cylindrical base with its axis as a center and moving a fluid discharge nozzle in the base end axial direction to form a continuous film. In that case, the gas reductive treatment is carried out in a manner that the gas dissolving amount of coating fluid is less than the saturated solubility of gas to the coating fluid under the discharge condition, and the coating fluid after the gas reducing treatment is applied. The gas reducing treatment is carried out in the method of heating the coating and deaerating fluid and then cooling in the state of being not in contact with gas or the like. Thus the generation foams in the coating fluid is eliminated and the defective coating is prevented.

Title: Method, device, and system for file synchronization for fault-tolerant network
Inventor: DAO THOMAS KIET
IPC: G06F12/00
Filed: 1999-11-16
Abstract: PROBLEM TO BE SOLVED: To prevent a communication service from being interrupted by synchronizing frames for a very short time by allowing a standby network entity to take over the function of an active network entity if the active network entity gets out of order. SOLUTION: When an active device 20A accesses a file in a 2nd memory 50A, the access is double in real time in a 2nd memory 50S that a standby device 20S corresponds to. When processors 30A and 30S always perform file synchronization at the time of file access to the device 20A, the active processor 30A sends a corresponding access request to the standby processor 30S through a network interface 35A and a communication link 15. Then the processor 30S processes the access request and returns confirmation to the processor 30A through the communication link 15 and network interface 35S. Consequently, the networks are given several-second file synchronism to evade service interruption.

Abstract: PURPOSE:To enable a die clamping force to be maintained stably by obtaining the thickness of a die in detecting the temperature of the die per each molding cycle and shifting a movable platen to the position producing a setting die clamping force. CONSTITUTION:During the die thickness adjustment performing at the time when another die is mounted, a die touching position (P), die thickness (e) and the temperature (Tp) of the die at that time are detected and memorized to a register (R), and the expansion rate (DELTAe) of the die is obtained from the difference between the die temperature (Tm) detected per each cycle through die temperature detecting means 9a, 9b and the memorized die temperature (Tp), and then the die thickness (e) per each cycle is obtained.

Abstract: PURPOSE:To change an etching rate of a polycrystalline silicon film and enable formation of a polycrystalline silicon pattern having excellent uniformity of size except for the polycrystalline silicon film at the area where impurity is not implanted by selectively implanting impurities into the polycrystalline silicon film on a semiconductor substrate.

Title: Spiral antenna
Inventor: UEMATSU HIROYUKI
IPC: H01Q11/04
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To reduce the outermost diameter of a spiral antenna without changing the lower working frequency limit of the antenna by connecting a radio wave reflection suppressing member to the end point of a conductor line. SOLUTION: Extension lines 1e and 1f made of metallic conductor are connected to end points 1c and 1d, i.e., winding end parts of spiral conductors 1a and 1b at each of both ends of lines 1e and 1f, and then extend toward a bottom plate in parallel to the points 1c and 1d respectively. Thus, both lines 1e and 1f pierce through an absorber 5 that is filled into a case 3 of a cavity structure. Thus, waves reflected from the points 1c and 1d are absorbed by the absorber 5 for the lines 1e and 1f which are connected to the end points of the lines 1a and 1b. Thus a radiation pattern is not disturbed even with frequencies radiated from the points near the winding end parts of the lines 1a and 1b. As a result, a satisfactory antenna radiation pattern is secured even with a lower frequency limit.

Abstract: PURPOSE:To enhance accuracy, strength and durability by alternately coaxially arranging a plurality of cylinders connected to a driving and a driven shaft at equal intervals, surrounding the cylinders by rubber elastic bodies, connecting the adjacent elastic bodies by a disk made of a synthetic resin, and forming axial projections between the cylinders. CONSTITUTION:Inner cylinders 20 each made of metal and connected to a shaft on a driving side and inner cylinders 21 each made of metal and connected to a shaft on a driven side are alternately arranged coaxially with each other on the same circumference. Rubber elastic bodies 22, 23 surround the whole circumferences of the inner cylinders 20, 21 so as to absorb vibration and alleviate an abrupt load during rotation, and further to reduce noise and absorb a bend and torsion of a coupling. The rubber elastic bodies 22, 23 are independently arranged in the predetermined portions of a disk 24 made of a synthetic resin so that tensile force between the inner cylinders 20, 21 during the rotation can be transmitted. Projections 26, each edge of which is formed into an arcuate shape surrounding the outer periphery of each inner cylinder 20, 21, are formed between the inner cylinders 20, 21 in the disc 24 made of synthetic resin, for restricting an angle between the driving shaft and the driven shaft if both the shafts are rotated with torsion. Consequently, it is possible to enhance accuracy, strength and durability.
