IPC: H01S3/097
Filed: 1983-11-01
Abstract: PURPOSE:To lessen bad influences, which are exerted upon the transformer and the discharge tube due to abnormal high voltage to generate on the output side of the high- voltage transformer when discharge of the discharge tube was started or the discharge ended, by a method wherein, even when the discharge tube is not discharging, voltage in a degree, that the discharge is not started, is kept having been always impressed. CONSTITUTION:When an oscillation starting switch 1 is in an ON state, the contact 8 of a zero detecting circuit 6 is in an ON state, and the output voltage of an oscillating circuit 2 is inputted in the input terminals of a transformer 3 through an auxiliary voltage resistor 7. At this time, voltage (namely, auxiliary voltage) lower than the discharge starting voltage of a discharge tube 4 has been impressed in between the anode 4a and the cathode 4c of the discharge tube 4. Accordingly, discharge of the discharge tube 4 is not performed under this condition. When the oscillation starting switch 1 is turned to OFF, the contact 8 of the zero detecting circuit 6 is turned to OFF. Accordingly, output voltage, which is outputted from the oscillating circuit 2, is directly impressed on the primary side of the transformer 3, afte the zero detecting circuit 6 detected a fact that the voltage between input terminals 6a and 6b is 0(V). At this time, discharge, in which the discharge current thereof is limited by a limiting resistor 5, is performed in between the anode 4a and the cathode 4c of the discharge tube 4.

Abstract: PROBLEM TO BE SOLVED: To remove nickel out of a silicon film which has been crystallized using nickel. SOLUTION: A nickel element is made to contact, while being held, the surface of an amorphous silicon film 102, as shown in 103. Then, crystalline silicon film 104 is obtained by a heating process. At that time, the behavior of the nickel element significantly promote crystallization. During the crystallization, the nickel element is diffused in the film. Then a mask 105 is formed, furthermore, such that a silicon film 106 containing phosphorous in high concentration is film-formed. By a heating process, the nickel element in the crystalline silicon film 104 is moved into the silicon film 106. Thus, the nickel concentration in the crystalline silicon film 104 is decreased.

Filed: 1998-07-07
Abstract: PROBLEM TO BE SOLVED: To solve the occurrence of unnecessary curves and wrinkles after election, and accomplish smooth ejection by providing a frame height adjusting member that heightens the apparatus main body during the use of a continuous material to be conveyed. SOLUTION: The desk printer 1 can use a continuous recording medium 10 as well as a fixed form recording medium as a fixed form material to be conveyed. The printer 1 is attached with a height adjusting member 3 rotatably to the printer main body 3, and when the frame height is heightened, the frame height adjusting member 3 is rotated downward to be set as a leg of the printer 1. When a fixed form recording medium is used, the frame height 3 is folded upward along the side face of the printer main body 2 so as to set the frame height adjusting member 3 low. During the use of the continuous recording medium 10, the height of the printer main body 2 is set high by means of the frame body adjusting member 3.  Thus, the continuous recording medium 10 being ejected hangs down through its dead weight between it and the installation face 5, and then is folded and doubled at the time when its tip end hits against the installation face.

Filed: 1994-07-27
Abstract: PURPOSE:To equalize the amounts of blowout from branch pipes by discharging fluid which is introduced from one suction pipe, from a plurality of branch pipes which are arranged with equal spacings so as to equalize pipe frictional resistance. CONSTITUTION:A metal or synthetic resin cylinder 1 is cut in a transverse manner. Both openings are blocked by an upper mirror plate 2 and a lower mirror plate 3 to form an airtight cylinder. A suction pipe 4 which is opened toward a center of the lower mirror plate 3 is projected upward from the center of the upper mirror plate 2. A plurality of branch pipes 5 are formed at positions with equal spacings from the suction pipe 4 of the upper mirror plate 2. Since the suction port 4 is formed on the center of the cylindrical airtight pipe, blowout into the cylinder is evenly diffused in the cylinder 1. The branch pipes 5 are arranged on the positions with equal spacings from the suction port 4, so that one pipe frictional value is shown from the suction port 4 to the branch pipes 5. The rate of blowout is kept constant from the branch pipes 5. This device can be adopted to a plurality of works for the same purpose.

Abstract: PURPOSE:To eliminate the revolution torque on alignment and improve the lubrication performance of the resin material poured-in, by improving the composition of the raw resin material and the heat treatment before and after molding processing. CONSTITUTION:An outer ring 1 coated with thermosetting adhesive 9 is inserted and set at a certain position in the bearing mounting/demounting hole 7 on a lower metal mold 4, and a preheated inner ring 2 is set at the projection 8 in the center. An upper metal mold 3 is fitted onto the lower metal mold 4, and fused resin material 10 is poured under pressure into the gap between the inner and the outer races. The raw material resin consists of polyamide resin, glass fiber powder, and polytetrafluoroethylene resin. After molding, a bearing A is taken- out from the metal mold and said bearing is heat-treated at the adhesive-hardening accelerating temperature of 140 deg.C or so, before the poured resin material  is hardened and shrunk. Thus, the adhesive 9 is rapidly hardened, and the resin material can be pulled and fixed onto the inner surface of the outer race 1.

Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To easily lay and store cords and to enhance appearance when they are stored. SOLUTION: A rack 8 is placed horizontally at the front of the back plate 5 of a desk 1. A movable plate 9 is provided in such a way as to swing freely so that it takes an upright position relative to the front end 8a of the rack 8 or a horizontal position where it continues with the rack 8 horizontally. At the upright position, the swinging end 9a of the movable plate 9 is placed in proximity to a bottom surface related to the top 2 of a desk 1, and eliminates an upward-open space. Further, a receptacle box 11 hidden beneath the back of the movable plate 9 because of the upright position of the movable plate 9 is provided above the rack 8 and either at the front of the back plate 5 or at the back of the movable plate 9. The swing of the vertical plate 9 to the horizontal position thus makes it easier to lay and store cords and to insert a receptacle into the receptacle box 11.  The swing of the movable plate 9 to the upright position hides any extra cords and the receptacle box 11 from the front of the desk 1 to enhance appearance and to decrease the amount of dust entering the box.
