Title: Production of raw material powder of high temperature superconducting ceramic
Inventor: IGAI SHIGERU
IPC: H01B13/00
Filed: 1988-03-04
Abstract: PURPOSE:To contrive improved fineness and uniformity of particle diameter of raw material powder, by contacting a solution of each compound of Bi, alkaline earth element and copper with a precipitant while irradiating a supersonic vibration and calcining the resultant co-precipitate. CONSTITUTION:A solution of Bi compound, alkaline earth element compound and copper compound is mixed with a precipitant while irradiating a supersonic vibration and a co-precipitate is formed. In another case, a solution of said compound is mixed with a precipitant and a co-precipitate is formed, thus a supersonic vibration is applied to the co-precipitate solution. The methods have no special restriction and many method are adoptable. Next, the solution containing a co-precipitate irradiated of supersonic vibration is separated by filtration and the co-precipitate is washed, dried and calcined. Fine raw material powder having particle diameters smaller than 1mu, a uniform particle diameter distribution and a uniform composition of the component is obtained by this method. The raw material powder is sintered to a superconducting ceramic having high density and high critical electric current density.

Title: Method for welding circumferences of pipes
Inventor: NAGAO KATSUNORI
IPC: B23K9/028
Filed: 1987-03-03
Abstract: PURPOSE:To improve working efficiency of the welding by providing shielding plates to the insides of pipes to be welded respectively to form the space on a joining part and controlling the flowing quantity of inert gas according to the pressure of the inert gas in the inside of the space. CONSTITUTION:The pipes 1a and 1b to be welded are supported horizontally on a driving roller stand 3 via outer rings 2 arranged on the outside peripheral surfaces of the pipes. An inner clamping device 4 provided with plural jacks 41 is set up on the insides of the pips 1a and 1b and the shielding plates 8 and 9 are installed thereon respectively. At the time of supplying inert gas to the inside of the space surrounded by the shielding plates 8 and 9, and the pipes 1a and 1b to perform the welding, a control part 17 controls the flowing quantity of the inert gas via a solenoid value 13 based on a level signal detected by a pressure converter 16. Since the inert gas pressure is maintained in an optimum state to form a penetration bead, the defective welding is prevented. Accordingly, the working efficiency of the welding is improved.

Filed: 1994-02-22
Abstract: PURPOSE:To display a background picture and to attain speedy display so that little video data can correspond to much playing data by changing set time for reading out edited video data in accordance with a genre and reading out the data based upon the set time. CONSTITUTION:Musical program data selected by a user through a remote controller 14a are read out from a hard disk 20 by a controller 12 and data corresponding to video genre data added to the musical program data are judged by the controller 12 and transmitted to a disk player 30 through a serial I/O circuit ISO 16. Then edited video data are divided into plural sections and reproduced at a time interval shorter than the storing time of data at random to obtain a background picture. When playing data are up-tempo data, up-tempo reproducing processing based upon prescribed short set time is executed. Consequently a background picture can be obtained and speedy video data can be displayed by allowing minimum video data required to correspond to much playing data.

Title: Image former
Inventor: TAMEHIRA MASATO
IPC: G03G15/00
Filed: 1990-02-28
Abstract: PURPOSE:To check a curl of fixing paper as well as to miniaturize a paper discharger by installing a curl preventing guide piece for preventing a curl of transfer paper run past an interval between both upper and lower pressure rollers, in the paper discharger. CONSTITUTION:Transfer paper is fixed by an upper heating roller 22 and a lower pressure roller 23 at a fixing unit 1, heading for a selector guide 7. At this time, the transfer paper is discharged as somewhat upper curlish along the roller 22, but since a curl preventing guide piece 24 is set up in proximity to the roller 22 and, what is more, it is formed into such a form as depressing the transfer paper immediately after its passing between both these rollers 22 and 23, the transfer paper trying to be curled upward produces a reverse curl, through which this upward curl is remedied. Moreover, as the transfer paper is kept away from the roller 22 earlier and time of the transfer paper going along the roller 22 is shortened to some extent, any residual heat in the transfer paper is lowered, so when the transfer paper is reached to the guide 7, it is set down to a cold state, so that any possible curl being produced at the guide 7 at time of face down is thus checked.

Filed: 1988-03-03
Abstract: PURPOSE:To perform a sharp marking, by a marking method wherein a laser light is irradiated on the surface of an article made of a material consisting of a phosphoric acid-containing inorganic substance. CONSTITUTION:As a marking material, all phosphoric acid-containing inorganic substances can be used, but a phosphoric glass or an ammonium phosphate anhydride is preferably used for obtaining a coating material having favorable transparency and color forming properties. The phosphoric glass is especially preferable for realizing superior transparency and color forming properties. The phosphoric acid-containing inorganic substance in a coating film is incorporated in the amount of 5-80wt.%, preferably 15-60wt.%. If the content is less than 5wt.%, a sharp contrast cannot be obtained. If more than 80wt.%, the physical properties are remarkably deteriorated. A sharp marking can be obtained by irradiating a laser light having a suitable strength on the surface of a resin molded material or resin coated material consisting of the phosphoric acid-containing inorganic substance through a mask.

IPC: B41J9/24
Filed: 1982-03-29
Abstract: PURPOSE:To enable to sufficiently introduce a magnetic flux coming out from a core in an increased quantity, by a method wherein a leaf spring and attracting parts of an armature member are formed as one body from the same monolithic magnetic material, and the thickness of the material at a peripheral part and that at an attracting position for a core are increased to a predetermined thickness. CONSTITUTION:The single sheet of a magnetic monolithic plate is subjected to blanking or wire-cut machining to form as one body a plurality of pieces centripetally stretched from the peripheral part 25a toward the center. The magnetic plate used is provided by preparing a thick plate of, for example, SK-5 and hardening to a specified hardness so that a spring part 25b has an appropriate strength. The peripheral part 25a is formed to retain such a plate thickness that the number of positions for fixing by screws can be reduced, and the attracting parts 25C are formed to retain such a thickness that a sufficient quantity of a magnetic flux can be introduced. Accordingly, the sufficient plate thickness enables to increase the magnetic flux, thereby securing the attracting force. In addition, since the elastic force of the spring part is enhanced, rapid movement of a wire can be achieved, and high-speed printing can be performed.
