Title: Two-points calking punch and method and device for calking two points simultaneously to planet carrier of pinion shaft
Inventor: OGAWA EIJI
IPC: B23P19/04
Filed: 1990-03-06
Abstract: PURPOSE:To calk and fix a pinion shaft to a planet carrier by giving specified shape and dimensions to a plate-shaped calked punch part obtained by elongating the tip part of a round bar. CONSTITUTION:The tip part of the round bar part 13a of a two-points calking punch 13 is elongated in the shape of a plate having a thickness (t) to form a calked punch part 13b. The central tip part of the calking punch part 13b is a straight part 13c having a length L which is parallel with the plate-shaped calked punch part 13b and orthogonal to the axial line of the round bar part 13a and an inclined part 13d having a crossed axes angle is formed on both sides in the direction along the calked punch part 13b of the straight line part 13c. The radius R of the corner part between the straight part 13c and the inclined part 13d is given by 1/4-1/2 of the thickness (t) of the calked punch part 13b. In this way, calking can be fixed and the life of the tool can be prolonged.

Title: Developing device
Inventor: YAMAZAKI HIDEO
IPC: G03G15/08
Filed: 1988-03-08
Abstract: PURPOSE:To easily set a developing agent layer carrying body in a state where the carrying body is not brought into contact with an electrostatic latent image surface and, at the same time, the same picture quality as that obtained when two-component development is made by causing charged insulating magnetic toner to be scattered between electrodes and adhere to and develop the picture part of the latent image. CONSTITUTION:In a developing area, insulating magnetic toner 7 is scattered over a developing agent layer carrying body 9 while the toner makes reciprocating movements along the alternating magnetic field produced between electrodes isolated from each other. When an electrostatic latent image 11 approaches the scattered toner 7, the toner 7 is attached to the latent image surface by an electrostatic force and the latent image is developed. The toner 7 which does not contribute to the development is passed through the developing area while the toner repeats the reciprocating movements and again moved to a developing agent hopper 6 by the magnetic force of a magnet roller 8. Therefore, the clearance between the developing agent layer carrying body 9 and the electrostatic latent image holding body 1 can be set larger and, accordingly, non-contacted development in which the carrying body 9 and holding body 11 are easily settable can be realized and picture which are less in photographic fog, etc., can be obtained.

Title: Production of thin metallic strip
Inventor: SATOU SHIYUN
IPC: B22D11/06
Filed: 1984-03-23
Abstract: PURPOSE:To obtain a large cooling effect and to obtain a thin metallic strip having a good characteristic and shape even if the thickness is large in the stage of ejecting and cooling quickly a molten metal onto the surface of a cooling base plate under movement and producing continuously the thin metallic strip by exerting pressing force to the unsolidified thin strip on the cooling base plate. CONSTITUTION:Molten metal flow is ejected onto a cooling base plate 6 under movement such as a cooling roll under rotation or the like from an aperture 1 to form a paddle 3 on the plate 6 when, for example, the nozzle aperture 1 for ejecting the molten metal is one. A thin strip 5 is drawn out of the paddle 3 and is solidified by quick cooling. A gas for pressing is blown to the unsolidified part 4 of the drawn out strip 5 from a nozzle aperture 2 for ejecting the gas for pressing. As a result, the strip 5 is pressed to the plate 5 and the contact force with the plate 6 is increased, by which the cooling effect is remarkably improved and the purpose is achieved.

Title: Danger-preventing method for liquefied gas burner
Inventor: SEKIGUCHI YOSHITOSHI
IPC: F23K5/00
Filed: 1979-05-02
Abstract: PURPOSE:To prevent the liquefied gas in a line from being flown into a combustion chamber, by a method wherein the liquefied gas remaining in the line running from a turning-off valve to a burner is exhausted through a purging line to the outside during the flow stoppage that is required at the time when liquefied gas in a liquid state is burned. CONSTITUTION:A residual liquid purging line 4 is connected to a lower portion of a piping 3 between an emergency turning-off valve 1 and a burner 2, the said line 4 being connected to a flare stack through the medium of a residual liquid purging electromagnetic valve 5 and a liquid pot 6. An opening area ratio of the burner 2 to the purging line 4 is set to be, say, about 1/20. The valve 5 simultaneously opens when the valve 1 closes. Since a resistance at a burner 2 side is far larger than that at a piping 4 side due to the opening area ratio thereupon, almost no liquefied gas flows to the burner 2 side, but it flows to the piping 4 for a short time. This permits the prevention of flow of unburning liquefied gas in a piping 3 into a combustion chamber following closure of the valve 1.

Title: Alloy for roll for transferring hot metallic ingot
Inventor: KUROKI HIRONORI
IPC: B21B39/00
Filed: 1981-04-09
Abstract: PURPOSE:To improve the working life of a roll by specifying C, Cr, Nb in alloy steel for the roll. CONSTITUTION:An alloy for rolls consisting, by weight %, of <=0.1 C, 10.0-14.0 Cr, 0.4-1.0 Nb, and the balance substantially iron and unavoidable impurities. Here, Cr is indispensable for improving oxidating resistance and corrosion resistance, and it is required to be above the lower limit because the improvement in elongation and drawing by Nb is effected on the higher side of Cr and in order to provide the effect of improving high temp. toughness by Nb. However, in excess of the upper limit, there is no considerable improvement in properties, and there is possibility of high temp. embrittlement. Ni converts microstructure to the single phase of ferrite including deposited carbide, improves corrosion and oxidation resistances and increases elongation, drawing and high temp. impact values. Even when it is heated at high temp., there is no degradation in strength and it is stable. Below the lower limit, no ferrite structure is formed at all and the elongation and drawing are degraded considerably; in addition, there is possibility of degrading elongation. In excess of the upper limit, embrittleness is liable to occur.

Abstract: PURPOSE:To eliminate a need for recorrection of the film sensitivity in case of film replacement or the like by holding contents of a second ISO value register if the same ISO value of a DX code that is read just before is read. CONSTITUTION:When the DX code is read by a DX code reading means 4, the DX code is decoded by a decoding means 5 to obtain an ISO value corresponding to the DX code, and it is discriminated by a discriminating means whether this ISO value is equal to the ISO value already stored in a first ISO value storage means or not. If it is discriminated as the result that they are not equal, the decoded ISO value is stored in first and second ISO value storage means by a writing means; but if it is discriminated that they are equal to each other, contents of the second ISO value storage means are held. Thus, it is unnecessary to correct the film sensitivity again when the current film is replaced with a film having the same ISO value as the current film, and the photographing operation is quickly started.
