Title: Lance apparatus for top blowing in converter
Inventor: YOSHIKA HIROSHI
IPC: C21C5/46
Filed: 1987-05-23
Abstract: PURPOSE:To reduce eroding speed of inner peripheral wall and to extend the service life of furnace lining by making difference of fitting state for lance nozzles to lance bodies, so that positions of blowing holes at peripheral direction to a converter body between one side lance and the other side lance are different. CONSTITUTION:At lower part of the nozzle 8 of the lance 5, 6, the plural oxygen blowing holes 11 are opened at some interval to the peripheral direction and axes of the above holes 11 are inclined to the lance axial line by alpha angle so as to blow oxygen outward diameter. Then, the above nozzle 8 is welded to the body 7 of the lance 5, 6, so that the positions of the holes 11 at peripheral direction to the converter body 1 at the time of blowing between the one side lance 5 and the other side lance 6 are different. By this method, the inner wall positions in the converter, at where the blowing oxygen from the holes 11 points, are different in the case of using the lance 5 or the lance 6. By alternatively using both lances 5, 6, the eroding position 13 of the converter refractory is dispersed, and the service life of the furnace lining can be extended.

Title: Wave absorber for 900mhz-band
Inventor: INAGAKI MASAYUKI
IPC: H01F1/34
Filed: 1992-04-20
Abstract: PURPOSE:To enable effective unwanted wave absorption thereby for achieving a thin wave absorber by using as a ferrite powder a manganese-zinc ferrite material whose permeability and dielectric constant are greater than a fixed value, respectively, and causing the ferrite powder to be contained within a specific range. CONSTITUTION:A manganese-zinc ferrite material having a permeability of 2000 or greater (at 100kHz) and a dielectric constant of 1000 or greater (at 100kHz) is used, and the ferrite powder is contained within the range of 55 to 95wt%. Further, a carbon powder or non-magnetic metal powder is contained by 5wt% or less, and an adjustment may be made so that the total content of the ferrite powder and the carbon powder or non-magnetic metal powder is 85 to 95wt%. As the non-magnetic metal powder, for instance, an aluminum or copper powder is used. The use of the high-permeability ferrite powder enhances the magnetic loss, thereby enabling the wave absorber to be thin. Moreover, the dielectric constant of the whole wave absorber increases, and the absorption peak shifts to the low frequency side.

Title: Production of shadow mask
Inventor: UEDA RYUJI
IPC: G03F1/00
Filed: 1988-05-25
Abstract: PURPOSE:To easily produce a shadow mask having fine hole of a required shape free from a defect without necessitating a backing stage by utilizing etching liquid having concn. difference and simultaneously photoetching both surfaces of a metallic plate for a base material. CONSTITUTION:A photoresist 3 is provided on both surfaces of a metallic plate 1 of a base material for a shadow mask. Then the metallic plate 1 is etched simultaneously from both surfaces by applying high-concn. etching liquid 6 on one surface and applying low-concn. etching liquid 7 on the other surface. In this case, the high-concn. etching liquid 6 is higher in viscosity and lower in etching velocity and on the other hand, the low-concn. etching liquid 7 is higher in etching velocity. After etching treatment is finished at a point of time when a prescribed through-hole has been formed, the photoresist 3 is removed. Thereby the fine hole having such a cross-sectional shape that irregular reflection of the electron beam is not caused in the side of the hole is perforated by one time of etching without performing backing and the shadow mask is obtained with good yield.

Title: Ink jet recording method
Inventor: KUBOTA HIDEMI
IPC: B41J2/045
Filed: 1988-05-25
Abstract: PURPOSE:To increase discharge without deterioration of image quality and making discharge of ink instable, by method wherein an operation in which after suddenly contracting an electric machine conversion element by applying an electric signal to the element, said state is kept as it is for a certain time, is repeated and thereafter, the element is returned to a state before applying the electric signal. CONSTITUTION:After contracting a conversion element 4 by applying a voltage step 14, voltage is kept constant for a certain time like a waveform part 15. One of positive parts 10, 11 which are generated by the voltage step 14 and are propagated in an ink passage reaches an ink discharge port 9 and an ink drop is formed. Then, when the element 4 is further contracted by applying a steep voltage rise waveform part 16 again, two positive pressure parts are further generated in the ink passage, and one of them reaches the ink discharge port 9 after a certain time has elapsed. Thereafter, voltage is gently decreased like a waveform part 17 and is returned to a state before applying a signal i.e., a waveform part 18 of zero in electricity. Since said conversion element 4 is gradually expanded in that case, any excess pressure wave is not generated in the ink passage.
