Abstract: PURPOSE:To obtain an infrared solid-state image sensing element being high in the numerical aperture of a photoelectric converter by forming a guard ring and Schottky barrier in a self-alignment system. CONSTITUTION:Silicon oxide film 118 is formed on a P-type semiconductor substrate 115 and silicon nitride film 119 is further formed on the silicon oxide film. Then, a resist 120 is applied and the silicon nitride film 119 is etched until silicon oxide 118 is exposed, an N-type impurity is injected so that an N-type impurity region 113 being a guard ring is formed. Then, the resist 20 is separated, only the part above the guard ring 113 is selectively oxidized so that a silicon oxide film is formed, and the silicon nitride film 119 is separated thereafter. Then, the difference in film thickness of the formed silicon oxide film is used so that only the silicon oxide film of the Schottky barrier part is etched and the surface of the silicon substrate 115 is exposed. After a metal is vapor-deposited the surface of the silicon substrate 115 is made into silicide so that the Schottky barrier is formed.

Title: Read only memory circuit
Inventor: OTANI AKIHIKO
IPC: G11C17/18
Filed: 1990-07-24
Abstract: PURPOSE:To reduce the energy consumption of a ROM by selecting the same fixed address bus as the one of a word line equipped with the highest number of memory cell circuits with lower energy consumption when the access of the ROM is not performed in an address selection device. CONSTITUTION:A fixed address bus 10 is selected by an address selection device 11 when the access of the ROM is not performed, and the lowest power consumption word line 6d is selected in an address decoder part 1. Since no transistor is formed on the lowest power consumption 6d at all, any bit lines 8a to 8d are maintained in a HIGH state. Then, this result is outputted by an output data bus 5. In this way, the lowest energy consumption word line 6d is selected for each clock when the access of the ROM is not performed, and the current does not flow through the bit lines since they maintain the HIGH state through a precharge period and through a word line selection period. Thus, the energy consumption can be restrained to the minimum.

Abstract: PURPOSE:To attain a high density and a high speed in a small-sized reel-to-reel device, by giving a compensating signal, by which the variance of the quantity of torque of a motor driving eacu reel has no influence upon the angular speed, to the driving means of each reel. CONSTITUTION:Reels 2 and 3 driven by motors 4 and 5 have tachometers 6 and 7, and their rotation numbers are detected by detectors 8 and 9 and are sent to a CPU18 to operate momentarily changing diameters of winding of reels. In accordance with diameters of winding of reels at this time, target values 33 and 34 of reel rotation numbers are sent to error detecting circuits 12 and 13. Actual rotation numbers 21 and 22 are compensated in circuits 16 and 17 by feedback to detect errors in circuits 12 and 13, and signals 29 and 30 are servo-amplified in amplifiers 10 and 11 to drive motors 4 and 5. Currents of motors 4 and 5 are detected in detectors 37 and 38, and signals 27 and 28 to compensate the reel inertia of the servo system are generated in operation compensating circuits 14 and 15 and are applied to error detecting circuits 12 and 13. Thus, the tape is always run in a constant speed even if diameters of winding of reels are changed, and a high density and a high speed are attained.

Abstract: PROBLEM TO BE SOLVED: To perform exposure, while placing the surface of a substrate such as a wafer on the image plane of a projection optical system with high accuracy, even when a travel surface and the image plane are not parallel when the substrate is moved. SOLUTION: When scan exposure is carried out by moving the wafer W with respect to an exposure region 3 of a projection optical PL via an XY stage 13, in synchronism with the movement of a reticle R to a lit area 2 via a reticle stage 4, multipoint AF sensors 19A and 19B pre-read a focus position on the surface of the wafer W, and the surface of the wafer W is placed on the image plane of the projection optical system PL through an automatic focusing system. At exposing, the quantity of variation of the attitude of a sample base 11, where the wafer W is mounted is measured by using a laser interferometer 16Y, etc., and according to the measurement results, a target value of the attitude of the sample base 11 for a wafer to be exposed next is set.

Title: Structure for correcting deformation error of t die lip driver
Inventor: TOMITA YOSHIYUKI
IPC: B29C48/08
Filed: 1988-08-09
Abstract: PURPOSE:To accurately control the opening of a lip by elongating upper and lower bellows when compressed air is fed to the bellows to operate a moment from a driver structure to the lip though a lip structure to displace it, and detecting the displaced amount by the user of a displacement sensor. CONSTITUTION:When compressed air is supplied from an air supply port 10 to bellows 2a, 2b, a moment is, since the axially central mechanical rigidities of the bellows 2a, 2b are lower than that of other structure between a body structure 1 and a driver structure 3, transmitted to an elastically deformed part 11. Since the part 11 has lower mechanical rigidity than those of the structures 1, 3, an elastic deformation occurs, and a lip 13 is moved. This displaced amount is substantially proportional to compressed gas pressure, and the opening of the lip can be arbitrarily controlled by controlling the compressed gas pressure. A displaced distance between the structures 1 and 3 is measured by a displacement sensor 15, fed back to be converted to a gas pressure, thereby correcting the displaced amount of a lip structure 12 due to a resin pressure.

Title: Method and apparatus for analysis of biological sample
Inventor: BACUS JAMES WILLIAM
IPC: G01N33/96
Filed: 1994-08-22
Abstract: PURPOSE: To analyze an organismic material of a cell and the others by using an image analyzing method, and quantitatively analyze polyploidy of the cell by using an image recognizing device. CONSTITUTION: A device displays an image of a cell group from one area of a slide of a microscope. This image is digitized further, and is stored in a memory. A processor device automatically discriminates respective cell examinees by a pattern recognizing technology from the digitized image. In an interactive program, an operator successively adjusts a focus to the cells, and makes a determination for classification and measurement on the respective ones. For a quantitative DNA nalysis, the measurement is performed by optical density of the cell examinees, and the classification is performed on whether the cells are normal or cancer by a pathologist. This determination can contain a judgment of whether a specific cell receives or rejects further processing.  The cell examinees can be classified into one of several classifications for a later statistical analysis when they are selected.
