Title: Positively chargeable toner
Inventor: TAKAGIWA HIROYUKI
IPC: G03G9/08
Filed: 1989-12-27
Abstract: PURPOSE:To obtain the toner which has excellent positive chargeability and exhibits excellent developability and colorability by incorporating a specific carbon black subjected to a surface treatment into the toner so that the toner has a specific dielectric constant of a specific range. CONSTITUTION:The carbon black which has 240 to 1,500m<2>/g BET specific surface area by a nitrogen adsorption method and is adequate for adjustment to the specific dielectric constant of the toner is adequately selected and the surface thereof is treated by an ionic silicone compd. This carbon black is incorporated into the toner so that the toner has 8 to 30 specific dielectric constant. Such carbon black is liable to constitute a structure and decreases the inter-particle distance of the carbon black with a lower content. The control of the specific dielectric constant to the 8 to 30 range is possible and since the content of the carbon black can be decreased, the toner having the adequate specific dielectric constant is obtd. without impairing the fixability. The toner which has the good positive chargeability, the excellent developability and the sufficient colorability is obtd. in this way.

Title: Fixation construction method of ground anchor using spring
Inventor: KODA MAKOTO
IPC: E02D5/80
Filed: 1994-12-13
Abstract: PURPOSE: To improve anchor functions by assembling a spring member to a connecting member so as to increase the spring function, and giving a tension force to the connecting member, when a structure is fixed to a resistant body buried in a shallow ground through a short connecting member. CONSTITUTION: When a ground 4 is contracted and sunk by a pressure contacting force 9 received from a structure 2, a spring function is operated by a connecting member 3 and a spring member 5. And as a result, even though the connecting member 3 is short, a tension force 8 applied thereto is not declined largely, and the pressure contacting force 9 is maintained so as to prevent the separation of the ground 4 and the structure 2. Consequently, even though a short ground anchor buried in a shallow ground is used, it can exercise the function sufficiently, and furthermore, a floating of the structure foundation and the like can be prevented.

Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To orient the magnetization of each magnetic film of multilayer structure, in a specified direction specified by design, by alternately applying uniaxial compressive stress or tensile stress to soft magnetic films which sandwitch a non-magnetic film, are vertically adjacent, and have magnetostriction. SOLUTION: A magnetoresistance effect multilayered film D is constituted by repeatedly forming a necessary number of layers (seven in this example) of soft magnetic films 31, 31' and non-magnetic films 32 on a non-magnetic substrate 30. A compartively large tensile stress is applied to the first soft magnetic film 31 and the third soft magnetic film 31, and the direction of their axes of easy magnetization is made right (arrow mark (a)). A small compressive stress is applied to the second soft magnetic film 31' and the fourth soft magnetic film 31', and the direction of their axes of easy magnetization is made perpendicular to the arrow mark (a).  Hence the direction of magnetization of the soft magnetic film 31 to which the large tensile stress is applied is films fixed by pins, and the direction of magnetization of the soft magnetic film 31' to which the small compressive force is applied is the film in which the direction of magnetization is made free.

Filed: 1989-12-26
Abstract: PURPOSE:To provide the titanium alloy with excellent corrosion resistance in a corrosive environment such as high temp. and high concn. nonoxidizing acid by incorporating specified amounts. of Mo, Nb, and Ru into a Ti alloy. CONSTITUTION:The compositional ratio of a corrosion-resistant Ti alloy is formed of, by weight, 10 to 40% Mo, 1 to 20% Nb, 0.05 to 2.0% Ru and the balance Ti with inevitable impurities. By the incorporation of Mo, a surface protective film in which Mo is concentrated is formed in a corrosive environment to improve its corrosion resistance. Moreover, by the addition of Nb, a surface protective film is formed in the same manner as Mo. The addition of Ru is the reason for polarizing the anode to the passive electric potential of Ti in a corrosive environment. By their synergistic effect, its corrosion resistance in the high temp. and high concn. aqueous soln. of H2SO4 or the like can be improved. Furthermore, maintenance cost is unneccessiated in the alloy.

(L, m, n, and O... each is a positive integers and P is an average synchronization of pattern for a pattern which becomes a reference phase and a phase difference corresponding to the combination of the sum of the phase differences, thus nearly eliminating odd-order distortion components for the component of fundamental synchronization. Even-order distortion components can be eliminated by obtaining the difference with an inverse-phase signal to cancel an offset voltage.
