Abstract: PURPOSE:To display the color of a scattering color filter regardless of the axis of deflection of a deflecting film by arranging the scattering color filter at a background part where the display of a liquid crystal cell does not change, and shifting the deflection of light at the background part. CONSTITUTION:Substrates 1A and 1B which have a couple of electrodes 2A and 2B are arranged having their electrodes surface opposite each other and their periphery is sealed with a peripheral seal 4; and liquid crystal 5 is charged therein to constitute the liquid crystal cell and a couple of polarizing films 6A and 6B are arranged on the screen of the liquid crystal cell.

IPC: F16D25/12
Filed: 1995-02-16
Abstract: PURPOSE: To minimize both the expense for components and for labor required to fasten a pressure medium line to the connection of a cylinder by enabling a radially expanded portion to be axially fixed at one end via a spring element positioned within a recess and at the other end via the support element of a connection. CONSTITUTION: The radially expanded portion 11 of a pressure medium line 8 has a conical external surface 32 in the direction of a plug-in end. When the pressure medium line 8 is pushed into a hole 6 in a connection 4, the legs 36 of a spring element 9 are pushed apart by the conical external surface 32 and are returned to their initial positions by spring force on the back of the radially expanded portion 11. Then the spring element 9 prevents backward movement of the pressure medium line even if the pressure medium line 8 is axially pulled in a releasing direction.  When the pressure medium line 8 is in a locked position, the conical external surface 32 of the expanded portion 11 is axially and at least slightly pushed into the bore of a support element 30 and their abutment allows the external surface 32 to be axially fixed to a stopper 34 via a seal 38 and radially fixed to the bore surface of the connection 4.

Title: Tig welding method
Inventor: KANBE YOSHIO
IPC: B23K9/16
Filed: 1985-03-15
Abstract: PURPOSE:To obtain the molten metal having the chemical component of the intermedium of a using filler material by melting two pieces of the filler materials having different chemical compositions in a one molten pool simultaneously. CONSTITUTION:Two pieces of filler materials are melted by arc 3 to form a molten pool 4 but the molten pool 4 is stirred up by the convection current caused by the arc force and heat of the arc 3 and becomes that which mixes the components of the two filler materials. And the component of this mixed molten metal can be adjusted if necessary. Namely the composition of the molten pool 4 can be changed by the adjustment in the feeding speed of the filler material because of the molten quantity being adjustable by changing the respective chemical component of the filler material and the feeding speed. Even in case of using more than three pieces of the filler materials, it is better to arrange so as to feed to the molten pool 4 from the front part and rear part of a tungsten electrode 6 or both sides of the front part and rear part. Therefore several kinds of molten metals 12 having the intermediate chemical component of the using filler material are obtainable.

Abstract: PURPOSE:To detect waterdrops adhered to the surface of a glass at a high sensitivity by such an arrangement wherein light rays radiated from a luminous device which are being propagated through the interior of a transparent plate are guided into plural photoelectric conversion elements through a photoconductive wave path, and the detected outputs of these elements are taken out as time serial signals. CONSTITUTION:A luminous device 30 composed of a luminous element 31 and a drive circuit 32 causes pulse-like photosignals to enter a glass plate 10 through a photoconductive wave path 40 at the incidence side. These light rays propagate through the glass plate 10 by repeating total reflection and enter a photosensor 33 in which plural photoelectric conversion elements 33a-33n are arranged in a row through a photoconductive wave path 41 at the radiation side. The output of each photoelectric conversion element is read out by a multiplexer 34 as a time serial signal, and applied to a detection circuit 37 through an amplifier 35 and a band-pass filter 36. If waterdrops adhere to the glass plate 10, the energy density of light rays entering photoelectric conversion elements is varied by each element and this variation of density can be detected by a decision circuit 38.
