Title: Mutual dispersion type two-phase ferrite composite material, carrier particle, dry developer composition, and development of electrostatic image
Inventor: BIJIYAI SHIYANKAA SAHA
IPC: G03G15/09
Filed: 1992-12-17
Abstract: PURPOSE: To develop a high density electrostatic image rapidly by using a developer which is a mixture of carrier particles, including a mutual dispersion type two-phase hard magnetic ferrite composite material which consists of a ferromagnetic phase and a ferroelectric phase and toner particles electrified in the opposite polarity. CONSTITUTION: For a ferromagnetic phase, a hexagonal hard magnetic ferrite material is used which has a specific coercive force and a specific dielectric magnetic moment and is expressed by Rx P(1-x) Fe12 O19 (R is a rare earth element, P is Sr, Ba, Pb or Ca, or one type of mixture of these, and x=0.1-0.4). For a ferroelectric phase, a ferroelectric material is used which includes one or more kinds of double oxides, consisting of one of Ti, Hf, Zr, Sn and Ge and either an alkaline earth element or Pb or Cd. The mole ratio of the ferromagnetic phase to the ferroelectric phase is 1:1-1:4. By using carrier particles, including such as these mutual dispersion type two-phase ferrite composite material, a high density electrostatic image can be developed at high speeds.

IPC: E02D5/58
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To impart a large elongation performance to a steel product by once stretching a reinforcement with a load exceeding a yield point strength to cause all of its yielding distortions, and then newly placing it under a tensioning state to fix it. SOLUTION: Ten high strength reinforcements obtained by once stretching a high strength reinforcement having a yield point strength of a prescribed value, for example, 75kg/mm<2> , or more with a load exceeding the yield point strength to remove yielding distortions are used as reinforcements 2, and these reinforcements are stretched with a load lower than the yield point load to impart a prestress to concrete 4, whereby a centrifugal prestressed concrete pile 1 is provided. Since the steel quantity to use is relatively increased more than the case of a conventional PC pile when a steel product having a yield point lower than that of the conventional PC pile is used, the initial bending performance is enhanced also against compression force or shearing force, compared with the same PC pile.
