Title: Producing device for metallic powder
Inventor: IMAHASHI KUNIHIKO
IPC: B22F9/08
Filed: 1980-12-05
Abstract: PURPOSE: To prevent the generation of variance in the gain sizes and apparent density of the metallic powder produced by providing wave suppressors for water surfaces within a cooling water spray tank in the lower part in producing metallic particles by pulverizing molten metal flow by means of water  films formed by the spray of high pressure water.  
     CONSTITUTION: Molten metal 2a in a tundish 2 is flowed out through a hole 2b in the bottom part, and the molten metal is pulverized by the inverted circular cone shaped water films 4a' formed by the spray of high pressure water 4a through a spray nozzle 4. At this time, plural sheets of wave suppressors 5 consisting of disc bodies 5 provided with a large number of small holes 5a are disposed at equal intervals in the cooling water 3a in a spray tank 3 in the lower part. By these devices, the generation of large waves at the water surface of the cooling water 3a in the tank 3 is prevented and the generation of  large variance in the grain sizes and apparent density of the formed by the  breakdown of the water films 4a' owing to the waves thereof is prevented.

Title: Image forming device
Inventor: NOAMI TSUNEO
IPC: G03G15/01
Filed: 1988-07-12
Abstract: PURPOSE:To prevent an excess of carriers by providing a destaticizing means to directly behind a 2nd developing means, disposing an auxiliary magnet member behind the developing means, and impressing an auxiliary bias weakening an electrostatic field in a direction in which a toner image formed by a previous developing means is electrically attracted. CONSTITUTION:Since a two-component containing developer made of toner and magnetic carriers C whose bulk density is <= 4g/cm<3> is used in a 2nd developing stage 3b, the force that the toner image T formed in a previous developing stage 3a rubs the developer is minimized. Here, the destaticizing means 6 lowers the surface potential of a latent image carrier 1, and accordingly the electrostatic attraction of the latent image carrier 1 to the magnetic carriers C drops, and the moving magnetic carriers C are readily attracted to the side of the auxiliary magnet member 7. Since a desired auxiliary bias Vb is impressed on the auxiliary magnet member 6, the existing toner image T is not attracted electrostatically. Thus, quality deterioration due to the excess of carriers can be prevented without affecting the toner image T.

Title: Production of thick steel plate
Inventor: HORIE MASAYUKI
IPC: B21B1/38
Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To enable the rolling of large rolling reduction by avoiding biting restriction to a rolling roll by controlling tension between stands to roll a steel plate so that compression stress acts on the steel plate between the respective stands of a tandem rolling mill consisting of plural stands. SOLUTION: Rolling torque and a rolling load in the state that a steel plate is bitten in a first rolling stand and there is no compression stress in the longitudinal direction are measured. The rolling torque and the rolling load in the state that the steel plate is bitten in a second rolling stand are measured. Compression stress in the longitudinal direction between the first stand and the second stand is calculated by these data. The number of rotations of the first stand is adjusted so as to generate compressed force in the prescribed longitudinal direction. When the steel plate is bitten in a third stand, the number of rotations of the second stand is adjusted in the same way. Successively the same operations are performed up to a final stand.

Filed: 1988-07-11
Abstract: PURPOSE:To remove produced ground dust so that a disk cassette can be loaded/unloaded easily by providing a rotary brush which operates in an interlocking way with disk cassette loading/unloading operation at a prescribed cassette loading position before a drive lever which releases the cassette. CONSTITUTION:A rotary brush 14 which is used for removing ground dust which is produced as a result of sliding friction between a driving lever 4 and window plates 13 of a disk cassette 11 and adhered to the lever 4 and plates 13 is provided inside a cassette holder 3 in the main body of this device so that the brush 14 can be positioned before the lever 4. The brush cleans the contacting surfaces of the plates 13 and lever 4 whenever the cassette 11 is loaded/unloaded in an interlocking way with the loading/unloading operations. Therefore, the lever 4 can smoothly load/unload the cassette because the frictional load when the lever is pinched between the window plates of the disk cassette can be reduced.

Next, when the metal panel 1 is subjected to bending processing in such a state that the lead panel 2 is arranged inside, compression stress is applied to the lead panel 2 but, since the lead panel 2 is soft, the lead panel 2 generates compression deformation easily and, since to shift is generated between the lead panel 2 and the metal panel 3 provided through the adhesive 4, no gull phenomenon is generated. Since the adhesive is provided between the lead panel 2 and the metal panel 3, the composite metal panel 1 is enhanced in rigidity as compared with the case of the lead panel along and the shear cutting thereof becomes possible in a large dimensional state at the time of cutting and cutting workability is enhanced. Further, the bonding work of the metal panel 1 to a wall can be performed in a large dimensional state and bonding workability is enhanced.
