Title: Projection aligner
Inventor: TAWA SUSUMU
IPC: H01L21/30
Filed: 1992-12-25
Abstract: PURPOSE:To improve the resolution and the depth of focus of an aligner without sharply lowering a throughput without largely changing an existing system by a method wherein a special filter or a special diaphragm which can set the distribution of intensity on an incident pupil in an apparatus projection lens to a specific condition is installed before or after a mixer lens. CONSTITUTION:The image of a mixer lens 9 is formed on an incident pupil 1 in a reducing projection lens 18 as a secondary light-source image. The optical intensity in the central part of the secondary light-source image is lowered, and the diameter within 6 is decided by a special filter 15 which is situated before the mixer lens 9. At this time, the distribution of intensity is strengthened by a first ring belt-shaped region surrounded by two nearly circular shapes in which the optical axis of an illumination system is used as the center and whose radii are R1 and R2 (where R2<R1) and by a second nearly circular inside region in which the optical axis is used as the center and whose radius is R3 (where R3<R1). When the mean value of the intensity in the first region is designated as L1 and the mean value of the intensity in the second region is designated as L2, L2/L1 = 0.2 to 0.8 is set. Thereby, the resolution and the depth of focus of the aligner can be improved.

IPC: G05D1/08
Filed: 1997-12-17
Abstract: PROBLEM TO BE SOLVED: To perform a directional control without requiring a matrix operation by setting a plurality of thrusters so as to have prescribed angles with respect to three orthogonal axes and be mutually separated, and arranging them in such a manner that any pair of thrusters generate one orthogonal torque. SOLUTION: In a spacecraft 10, a controller 16 receives signals of a posture sensor 14 related to orthogonal X, Y, and Z axes and ON/OFF controls a plurality of thrusters 1-4. The thrusters 1-4 are arranged with selected positions and directions of thruster nozzles to generate controlled X, Y and Z-axial torques, respectively. Namely, the thrusters 1-4 are regulated so that the torque laid along each axis of each thruster 1-4 is equal to the torques laid along each axis of the other three thrusters, or the absolute values are mutually equal with opposite directions. Consequently, when a pair of thrusters are selected from six possible pairs obtained from the four thrusters 1-4 and ignited, a positive or negative torque laid along only one of three axes of the space craft 10 can be generated.

Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To handle an image with efficiency according to the identity between the image to be processed and a specific image even when image data are sent to and received from external equipment by providing an image input means, a receiving means, and a common decision means. SOLUTION: According to the decision result of a connection recognition signal 1107, the output image of an image scanner part 1101 and an input image to a printer part 1102 are processed by AND gates 1108 and 1109 and then when the substrate of a decision circuit 1105 is demounted, copying operation, FAX transmitting operation, and FAX receiving operation can be all inhibited. Thus, all output operations including not only copy output, but also output to a communication line can be controlled, so even if an image decision board is detached on, for example, a user side, a specific image of a specific document is automatically prevented from being outputted to securely evade forgery.

Abstract: PURPOSE:To allow bar graph display on an inexpensive downsized display section by emitting light from light emitting elements on a display board between an original point and a light receiving point by means of the light emitted from a light emitting body moving while interlocked with a recording pen. CONSTITUTION:When a recording pen 3 is moved up and down by means of a motor, a light emitting body (light emitting element) 12 carried on the pen 3 also moves up and down and the light emitted therefrom impinges on five continuous elements (Cds) in an array (drive section) 10. When the pen 3 moves upward from an original point (lowermost point) and the light emitted from the element 12 impinges on Cds R1-2-R5-2 in the array 10, resistances thereof decrease and the light emitting elements (LEDs) 9 in eleventh and subsequent LED arrays (display section) do not light. In other words, LEDs 9 only in first to tenth arrays light and other LEDs 9 unlight thus indicating the position of the pen 3.

Abstract: PURPOSE:To accurately control the acid concn. in pickling tanks with continuous type band steel pickling equipment which continuously pickles and descales a hot rolled steel sheet. CONSTITUTION:The band steel S which is a traveling material to be treated is subjectecl to the pickling treatment in the pickling tanks 1, 2, 3 which are arranged in plural arrays in a progressing direction. A fresh acid liquid is supplied to acid liquid circulating systems of the respective pickling tanks from a supply piping 31 for cascade and branched supply pipes 32, 34, 36 from a supply pipe 23. The circulating tanks 11, 12, 13 are located in correspondence to the respective pickling tanks 1, 2, 3 and are connected by liquid supply pipes 20, 17, 14 and return pipings 21, 18, 15. These systems are so constituted that the waste acids discharged from the acid liquid system of the inlet side pickling tank 1 for the band steel are partly returned by the circulating line 38 to the acid liquid circulating systems of the pickling tanks on the upstream side viewed from the flow of the acid liquid. Consequently, the concns. of the HCL and FeCL2 of the acid liquid in the respective pickling tanks are maintained at an adequate distribution at all times even if the amt. of the steel sheets to be treated fluctuates.
