Title: Zeolite for detergent builder
Inventor: ROBEERU GURUSE
IPC: C11D3/12
Filed: 1983-06-17
Abstract: Type A, especially type 4A zeolites are well adapted as detergent builders, said zeolites comprising (i) primary particles having a mean particle diameter ranging from 0.1 to 10 mu , (ii) a cation exchange capacity in excess of about 100 mg CaCO3/g of anhydrous material, and (iii) a rate constant, relative to the surface area of the zeolite per liter of wash solution, in excess of about 0.15 s-1 lm-2. The builders are prepared by first determining the value of the rate constant for a given zeolite sample. Since a higher rate constant value corresponds to a lower degree of salt incrustation on fabrics, only those zeolites having a value above the predetermined minimum will be incorporated into detergents. Thus, zeolites otherwise appearing identical can be differentiated, with only those not causing high levels of incrustation being selected.

Title: Copper alloy for wiring connector
Inventor: YAMATO KOUZOU
IPC: C22C9/04
Filed: 1984-05-29
Abstract: PURPOSE:To obtain the titled Cu alloy having high strength, workability, superior compression connectibility, glow resistance and resistance to the growth of cuprous oxide by providing a specified composition consisting of Zn, Sn, Si and Cu. CONSTITUTION:This Cu alloy for a wiring connector consists of, by weight, 1- 15% Zn, 0.3-2.0% Sn, 0.1-1.5% Si and the balance Cu with inevitable impurities. Glow is hardly generated, cuprous oxide is hardly grew, and the generation of heat from a connected part is prevented. Among said components Zn inhibits the growth of cuprous oxide in case of >=1%, but >15% Zn deteriorates the glow resistance. Sn improves the resistance to the growth of cuprous oxide even in case of <0.3% or >2.0% but does not improve the glow resistance. Si improves the glow resistance and the resistance to the growth of cuprous oxide in case of >=0.1%, but >1.5% Si deteriorates the bendability as well as the glow resistance.

Title: Mixed and compound damping material
Inventor: JIYON EE ROBAATSU
IPC: F16F7/08
Filed: 1989-05-01
Abstract: PURPOSE: To obtain high damping of a combined damping material by hysteresis damping and Coulomb damping by making the yield stress of a first element larger than that of a second element, and providing a friction generating means which frictionally contacts the surface of the damping material when the material is strained by a load. CONSTITUTION: When a complex 20 is stressed by a weight W, strains are generated in respective parts of the complex. In this case, tension acts on the upper side of an intermediate shell 21 and an outer shell 23, while compression acts on the underside of these shells, and the intermediate shell 21 is strained in its elastic limit. Since a soft core 22 is integrally connected to the intermediate shell 21, the core is plasticized to generate heat when stress over critical is applied to it, and the material is damped when repeated loads are applied. When the intermediate shell 21 and the outer shell 23 are strained, since both the elements are not integrally connected, relative movement of both the elements generates friction, which converts mechanical ettergy into heat energy, and the repeated loads increase damping.  Thus, a combined effect of Coulomb damping and hysteresis damping can be obtained.

CONSTITUTION:Whether each block is a shading picture or a character picture is decided from two deciding conditions of (1) whether the maximum level value of a variation portion of a tone between plural blocks of a dither picture exceeds a prescribed level or not, and (2) a picture element of a block of a single threshold level is not all white nor all black. A signal 1 in which the shading picture and the character picture are mixed is inputted in parallel to comparators 10, 11. The comparator 10 binary-codes the signal 1 by a single threshold level 2, and the comparator 11 binary-codes it by a dither threshold level 3. The binary-coded signal is brought to a logical operation and is inputted to a multiplexer 33, in which in accordance with the conditions (1), (2), it is made to pass through a simple binary data and a binary dither data when the input is a character picture, and when it is a shading picture, respectively.
