Title: Formed articles having coated layers
Inventor: TAKADA RYOICHI
IPC: C08J7/04
Filed: 1992-02-07
Abstract: PURPOSE:To provide formed articles with no fluctuation in the coated layers each article by forming the coated layer on the resin base material and forming the exposed part whose exposure is gradually changed by removing a part of the coated layer with laser beams or the like. CONSTITUTION:The base material 1 (for example, the back panel of a car) formed from a synthetic resin such as poly(methyl methacrylate) or polycarbonate is applied and baked with an acrylic lacquer on its inside surface to form a coated layer 2 of 10 to 30mum thickness. Then, the layer beam L is focused on the part from which the coated layer should be removed and allowed to irradiate the part with the output of 1 to 30W/m<2>. Only the coated layer irradiated is vaporized off. At this time, as the laser goes near the edge part, the interval I between the slit 3 of the removed coat layer and the slit 3 are made narrower (I1<I2<I3...) to form the exposed part in which the exposure density gradually changes. Thus, the formed articles having uniform color tone to the gradual change in the coated layer are produced.

Title: Reflection type photo amplifier
Inventor: MASUDA SHIGEFUMI
IPC: H01S5/00
Filed: 1987-03-12
Abstract: PURPOSE:To increase a light output and reduce the noise level without using an optical isolator, by rotating a polarized light output 45 deg. in the direction of polarization, introducing it into a laser medium provided with a reflecting film on the terminal end, amplifying it, reflecting it and rotating again the direction of polarization 45 deg. to obtain an output. CONSTITUTION:Polarized light P is input to a polarized beam splitter 1, whose light output is made to pass through a Farady rotator 2 to rotate the polarization direction 45 deg.. This light is input to a laser medium 3 provided with a non- reflecting film on an input end and a reflecting film on a terminal end. It is amplified and then reflected by the reflecting film 5. The output light from the input end is again input to the Farady rotator 2 to rotate the polarization direction 45 deg.. This light is again input to the polarization beam splitter 1, and an output light S is obtained as a reflected light. The light by spontaneous radiation in the laser medium 3 is entirely reflected by the reflecting film 5, and output together with a residual reflected light. Therefore, the output light is almost doubled, and so the noise level of an amplifier can be reduced. Further, as the light reciprocates in the laser medium 3 and is subjected to a spontaneous radiation, an expensive isolator of high quality is not required.

Title: Detecting method of accident point on power transmission and distribution line by photosensor
Inventor: KURIHARA MASAYUKI
IPC: G01R31/08
Filed: 1984-03-27
Abstract: PURPOSE:To reduce speedily and securely the cost of construction and detect the generation point of a wire breaking accident by providing an optical fiber line which pieces photosensors provided at respective accident detection points successively and sends light to the respective photosensors in series. CONSTITUTION:Light pulse signal transmitters 7 and 8 are controlled by a pulse signal oscillator 6 to send out light pulse signals PA and PB continuously, and photocouplers 9 and 10 send them into the optical fiber line PL. If one wire breaking accident occurs between accident detection point (c) and (d), zero- phase voltage detectors Fd-Fn generate outputs although respective zero-phase voltage detectors Fa-Fc between a power station T to the accident generation point (c) are zero. Therefore, light which passes throgh the zero-phase voltage detectors Fd-Fn from the accident generation point (c) changes in plane of palarization to vary the level of a light pulse signal. Then, level variation detectors 13 and 14 connected to optical receivers 11 and 12 detect the points of time when the level varies and an accident point detector 18 calculates the time difference to detect the accident generation point.

Title: Moving control system of electromagnetically driven shutter
Inventor: DATE NOBUSHI
IPC: G03B7/083
Filed: 1979-05-10
Abstract: PURPOSE: To increase the speed in the initial period of shutter travel, by designing to obtain a stronger driving force in the initial period of shutter travel.  
     CONSTITUTION: When a driving current is passed into a coil 1a for driving a front blade, the coil 1a exerts force in upward direction, which causes a shutter front blade 1 to move upward. In this case, the interval between a yoke 2 and yokes 3, 4 grows wider toward the coil traveling direction, so that the driving force of the drive source to run the front blade 1 is larger in the initial travel period and decreases as nearing the end of travel. In specified second time after start of travel of the front blade 1, an electric power is supplied to a coil 11a for driving the rear blade, and a shutter rear blade 11 is caused to run. The force of the drive source to drive the rear blade 11 is larger in the initial travel period, as in the case of traveling of front blade 1, and decreases as nearing the end of travel. Thus, the travel speeds of the both blades 1, 11 are kept almost at a constant value while passing over the surface of exposure opening window 10 of a camera, so that a uniform exposure may be obtained.

Filed: 1987-03-12
Abstract: PURPOSE:To obtain a core tube for a metal vapor laser having a long life and excellent characteristics, by using a specified alumina ceramics polycrystalline material. CONSTITUTION:An alumina ceramics polycrystalline material is used, wherein the total amount of impurity except magnesia or magnesium compounds is smaller than or equal to 1000 ppm, and the density is more than or equal to 3.95 g/cm<3>.

As to the correlation between the total amount of impurity except magnesia and characteristics of a metal vapor laser tube, the smaller amount of impurity the preferable, and the value less than or equal to 1000 ppm is satisfactory. When the density is more than or equal to 3.95 g/cm<3>, the plastic deformation speed is small at a temperature higher than or equal to 1500 deg.C, operating temperature of the metal vapor laser tube. Therefore, a laser alumina core tube having excellent characteristics and a long life can be obtained.

Then while current is allowed to flow via the hook 24 and to flow to the earth from the lower end of the substrate member 22, enamel frit is applied to the substrate member 22 fitted to the supporting frame 20 by an electrophoresis method. In this case, the electric force lines (a) are unallowed to act on the supporting frame 20 made of the insulator and therefore unconcentrated to the circumferential part of the substrate member 22 and thereby excess enamel frit is unstuck. A plurality of enameled substrate members 22 having the uniform film of enamel frit are obtained by calcining the substrate member in a kiln and thereafter cutting the substrate member 22 in the connecting parts 26.
