Title: Illuminator for image exposing device
Inventor: KAKIYA YOTARO
IPC: G03G15/04
Filed: 1991-03-12
Abstract: PURPOSE:To offer an illuminator for an image exposing device preventing the occurrence of shadow of an original with comparatively simple constitution. CONSTITUTION:A reflecting plate 8'for projecting light from an exposing lamp 2 on an original surface is composed of three reflecting parts, and has a function for reflecting the light from the exposing lamp 2 to a third receiving part 23 opposite to a first reflecting part 21, and simultaneously, a mirror surface having the highest reflectance. A second reflecting part 22 has the function for directly irradiating the exposing surface of the original with the light from the exposing lamp 2, the third reflecting part 23 has the function for mainly irradiating the original surface with the light from the first reflecting part 21 and the exposing lamp 2, and is installed on the side opposite to the exposing lamp 2, with respect to an optical path for an exposure, and the reflectance of the reflecting surfaces of the second and third reflecting parts is set lower than that of the first reflecting part. Therefore, the exposing surface of the original can be uniformly illuminated from the left and right with one exposing lamp, and the occurrence of the shadow is prevented even when a patched original, etc., are illuminated.

Title: Ultrasonic flaw detection
Inventor: SUZUKI SHINICHI
IPC: G01N29/26
Filed: 1991-03-12
Abstract: PURPOSE:To reduce ultrasonic flaw detection time for a work which is subjected to friction-pressure-welding or welding. CONSTITUTION:A junction surface S of a work W which is subjected to friction- pressure-welding is divided into regions Z1, Z2. When ultrasonic probes 11A and 11B which generate an ultrasonic beam P are moved from positions X11 and X22 to positions X21 and X22 for performing flaw detection of the region Z1, a rotary speed of the work W and a traveling speed of the ultrasonic probes 11A and 11B are increased for performing a rough flaw detection. When the ultrasonic probes 11A and 11B are moved further from the positions X21 and X22 for performing flaw detection of the region Z2, the rotary speed of the work W and the traveling speed of the ultrasonic probes 11A and 11B are reduced for performing a precise flaw detection.

Title: Apparatus for detecting moving body
Inventor: UEDA TERUO
IPC: H04N7/18
Filed: 1990-03-01
Abstract: PURPOSE:To automatically detect a specific movable object from an object to be imaged without an error signal by setting the passing level of a threshold filter to the inherent value of the specific object. CONSTITUTION:A television imaging part 4 uses only the signal of the certain temp. range or infrared radiation range of an object to be imaged. When only a moving person is desired to be detected, by setting the passing level of a threshold filter 5 to a signal level from 35 to 40 deg., the threshold filter 5 issues output only when the person is present as the object to be imaged. Further, since the movement detection signal 7 of the moving part of a specific object is outputted by taking the difference of the corresponding point between time series frames by a difference-between-frame detection part 6, no error signal is outputted even when a tree moves.

Title: Base paper for vinyl wallpaper
Inventor: YAMAJI YASUYUKI
IPC: D21H17/14
Filed: 1994-03-17
Abstract: PURPOSE:To obtain base paper for vinyl wallpaper capable of controlling the hydrogen chloride gas concentration contained in waste gases to a low value even when the vinyl wallpaper rejected as a waste by repapering, etc., is disposed of by incineration. CONSTITUTION:This base paper for vinyl wallpaper is obtained by using base paper prepared by fixing and supporting one or two or more selected from the group of calcium carbonate, magnesium carbonate, dolomite, hydroglosser and hydrotalcite on a fibrous substance consisting essentially of cellulosic fibers as base paper for the vinyl wallpaper. When the vinyl wallpaper is disposed of by incineration, hydrogen chloride generated from vinyl chloride is neutralized with the inorganic powder. As a result, the hydrogen chloride gas concentration in waste gases can be reduced. When the calcium carbonate, magnesium carbonate or dolomite without any self-extinguishing properties is used, flame retardant treatment is carried out so as to enhance the flame retardancy of the base paper.

Title: Level detector
Inventor: TANAKA TOSHIHARU
IPC: G01F23/28
Filed: 1984-03-13
Abstract: PURPOSE:To make it possible to detect a level with high accuracy, by constituting a level detector so as to drive the same by arranging the vibration plate of the level detector in parallel or slightly oblique relation to the level surface of an object to be detected. CONSTITUTION:The vibration plate 7 of a level detector is arranged so as to be made parallel to the level surface 9 of an object 8 to be detected and a piezoelectric element 5 is vibrated by input voltage in a C-D direction vertical to the surface of said vibration plate 7. When a large amount of the objects 8 to be detected are preset and the vibration plate 7 is embedded in the objects 8 to be detected, vibration is suppressed and output voltage is low. Contrarily, when the objects 8 to be detected are reduced and the level surface 9 is lowered below the vibration plate 7, the suppression of vibration is relieved and the vibration plate 7 is operated in large amplitude while output voltage becomes high. By this method, a level can be detected with extremely high accuracy.

Title: Laser device
Inventor: KAWAKITA TAMOTSU
IPC: H01S3/0977
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To provide a laser device which can prevent heavy wear-out of a preliminary ionizing pin for causing discharging operation to radiate ultraviolet light for preliminary ionization of a gas laser due to concentrated electric field. SOLUTION: Edge parts 11 of an end face of a preliminary ionizing pin 3 where an electric field is expected to be concentrated are covered with an insulator 15. Since the edge parts 11 are covered with the insulator 15, discharge concentration can be avoided. The intensity of the electric field on a surface of the pin not covered with the insulator 15 is even and discharge takes place in the even electric field. Thus concentrated discharge can be avoided and wear-out of the preliminary ionizing pin can be avoided.

Abstract: PROBLEM TO BE SOLVED: To obtain an arrangement wiring result from which an error is eliminated by detecting the hold time error of a path, selecting a delay gate capable of evading the hold time error in a range in which a maximum delay time error is not generated for the net on a path in which the error occurs and inserting the delay gate. SOLUTION: By using a path delay analysis means 104, a hold time error detection means 106 detects a path in which a hold time error occurs by calculating the delay time of the path between each flip flop, adding the clock skew determined by a clock skew calculation means 105 and comparing the clock skew with the minimum delay time constraint of path delay constraint information 114. A delay gate insertion means 107 inserts the delay gate necessary for eliminating the hold time error by referring to delay information 113 and updates logical connection information 111.

Title: Method for detection of gyration information and gyro device
Inventor: HAYASHI SOKICHI
IPC: G01C19/00
Filed: 1995-03-08
Abstract: PURPOSE: To stabilize detection sensitivity when a moving body is inclined whereby a detection axle of a rate gyro is always vertically maintained when the moving body is in the rolling or pitching movement. CONSTITUTION: A sealed type vessel 10 is filled with a liquid 13 such as oil by means of a base 11 and O-ring 12. A rate gyro 18 is so constituted such that it can freely move along with a pendulum 17 by slow movement due to a viscous resistance of the liquid 13 in the vessel 10. A gyro device 2 for detecting gyration movement having the above mentioned structure is attached to a top section of a moving body. When the moving body turns during the arising of a slope, the rate gyro 18 always maintains its attitude in the vertical direction by virtue of action of a gimbal section 17A of the pendulum 17. Thereby, it is possible to obtain the detection sensitivity the same as that in the detection action in a normal and horizontal positioning condition.
