Title: Light beam scanner
Inventor: NAITO HIROYUKI
IPC: B41J2/44
Filed: 1989-09-20
Abstract: PURPOSE:To obtain the scanner of a small size and a high speed by displacing one piece of mirror by the magnetic force generated by a set of a permanent magnet and a driving coil. CONSTITUTION:The front surface of the mirror 1 for reflecting a light beam is a reflecting surface and is fixed at a linear fulcrum 3 to a supporting base 2. The permanent magnet 4 having magnetic polarities in the direction perpendicular to the reflecting surface of the mirror 1 is provided on the side face on the opposite side and the mirror 1 can be moved vertically in an arrow 7 around the fulcrum 3. A driving coil 5 is fixed to the supporting base 2 on the surface facing at a suitable spacing to the magnet 4 and is connected to a driving signal 6. The polarities of the magnet 4 are assumed to be an N pole in the front surface direction of the mirror 1 and an S pole in the rear surface direction of the mirror 1 at this time. The mirror 1 is held static at a mid point while the driving signal 6 is not impressed. Reaction acts between the magnet 4 and the coil 5 and the magnet 4 is pushed upward in an arrow 7 direction when an electric current is so impressed that the front surface of a coil 5 acts as the N pole and the rear surface as the S pole. The mirror 1 is eventually tilted upward around the fulcrum. The mirror 1 is tilted backward when the current to be impressed to the coil 5 is reversed.

Abstract: PROBLEM TO BE SOLVED: To activate each impurity implanted region by making specific the ratio of hydrogen concentrations in n-type and p-type impurity implanted regions, on the occasion of emitting a high-energy beam on hydrogen, n-type and p-type impurity implanted regions formed on the same substrate, and activating impurities. SOLUTION: A buffer layer 10 and a polycrystalline silicon film 11 are formed on an insulating substrate 9, and this polycrystalline silicon film 11 is composed of a channel region 11a and a source/drain region 11b. An n-channel is formed by implanting impurities such as phosphrus, arsenic, into a polycrystalline silicon and a p-channel is formed by implanting impurities such as boron. In this process, it becomes possible to perform simultaneous activation of the n and p-channels by the use of an ELA activating method, capable of obtaining a high ratio of activation by a low-temperature process, by setting the hydrogen concentration ratio of a p-channel source/drain region 11p to an n-channel source/drain region 11n in a range of 0.5-2.

A diaphragm surface R1 and the first optical element B1 are fixed at the time of variable power. The second optical element B2 moves to a Z minus direction at the variable power from a wide angle end to a telephoto end. The 10th surface R10 which is the image plane moves once to the Z minus direction then to the Z plus direction at the time of variable power from the wide angle end to the telephoto end.  At this time, the spacing between the first and second optical elements B1, B2 narrows and the spacing between the second optical element B2 and the image plane R10 widens.

Abstract: PURPOSE:To detect a diseased part shade with high accuracy by providing a difference arithmetic means obtaining a 2nd diseased part shade emphasis picture and a diseased part shade extraction means extracting a diseased part shade from the 2nd diseased part shade emphasis picture to the detector. CONSTITUTION:A tumor shade emphasis means 51 in a computer system generates a tumor shade emphasis picture in which a tumor shade is emphasized on an X-ray picture based on an inputted picture data SD. Moreover, a vein shade emphasis means 52 generates a vein shade emphasis picture in which a vein shade is emphasized on the X-ray picture. Then a difference calculation means 53 releases the emphasis of the shade emphasized by the vein shade emphasis picture from the shade emphasized by the tumor shade emphasis picture and generates a 2nd tumor shade emphasis picture in which only the tumor shade is truly emphasized. A tumor shade extraction means 54 extracts only the true tumor shade based on the 2nd tumor shade emphasis picture with high accuracy. Thus, it is prevented that part of a linear pattern is extracted as a tumor shade and the tumor shade is extracted with high accuracy.

Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To simplify a hardware configuration by providing a defect relieving analyzer having a row fail number storage memory which directly stores the number of fails every row address of a semiconductor memory to be tested and a column fail number storage memory which directly stores the number of fails every column address. SOLUTION: Write enable is not allowed and an output is zero at the time of designating an address 0, 0 in order of a row and a column with respect to addressing in the semiconductor memory to be tested. Next, 0 being cleared data is read from the row fail number storage memory 3 and inputted with a row fail number adder 31. When an address 0, 1 is designated, a storage content of the row fail number storage memory 3 is 0, and then the storage content of the memory 3 is not changed even though an address 0, 2 and succeeding addresses are successively designated. When an address 0, 5 is designated, the row fail number storage memory 3 becomes write enable and the storage content of the memory is rewritten from 0 to 1. Thus, the capacity of the fail number storage memory is reduced and the hardware is simplified.

Abstract: PURPOSE:To improve the general usability of a connector for AV apparatus such as a TV receiver and a video tape recorder by making it possible to adjust the interval among an image pin plug, a left voice pin plug, and a right voice pin plug by means of a presser bar. CONSTITUTION:When the center of a presser plate 5 is pushed by a force F, the interval between an image pin plug 1 and a left voice pin plug 2, and the interval between the left voice pin plug 2 and a right voice pin plug 3 can be widened equally. When the right side of the center of the presser plate is pushed down by the force F, the interval between the left voice pin plug 2 and the right voice pin plug 3 is widened. When the left side of the center of the presser plate 5 is pushed by the force F, the center of the presser plate 5 is pushed by the force F while the presser plate 5 is slid to the left side by the force F to widen the interval between the image pin plug and the left voice plug 2. The interval among these three pin plugs can thus be adjusted freely.

Title: Method and apparatus for evaluating surface condition
Inventor: SATO TAKAO
IPC: G01N23/227
Filed: 1989-09-22
Abstract: PURPOSE:To prevent alteration of an object to be measured and disturbance of measurement environments for permitting quick and highly sensitive measurement by radiating ultraviolet rays in pulses in a short time and collecting generated electrons as current. CONSTITUTION:When pulse-like ultraviolet rays emitted from a pulse ultraviolet radiation lamp 1 is radiated to an object 4 to be measured placed in the atmosphere, pulse-like electrons are emitted in the atmosphere due to a photoelectric effect of photo excited exoelectron emission. A part of the electrons are trapped by oxygen in the atmosphere to be oxygen ions, a part of which are collected by a detector 2. Electric charge of the detected oxygen ions becomes a pulse-like electron current. The electron current is amplified by a current-voltage exchange amplifier 6 to be output as a pulse-like voltage value and measured by a pulse signal supporting measurement device 7 such as a storage synchroscope or a boxcar integrator. The measurement results are stored in a memory device 11. Thus alteration of the object to be measured and disturbance of measurement environments can be prevented to enable rapid and highly sensitive measurement.
