摘要:
The present invention furnishes a method for producing mineral wool wherein a molten mineral material is fed into a spinner (1) the peripheral wall (2) of which comprises a multiplicity of orifices with small diameters wherethrough the mineral molten material is centrifuged to form filaments which are subjected to a supplementary attenuating effect of a gas flow flowing along and heating the peripheral wall (2) of the spinner (1) and generated by a concentric annular burner (8) arranged concentrically to the spinner (1), and wherein the exit area of the burner (8) is subdivided into an annular radially inner hot zone and an annular radially outer cooling zone of substantially lower temperature; the invention moreover concerns an apparatus for implementing the method.
摘要:
In a vehicular electric power generation apparatus having an a.c. generator (1) and an engine (2), a rotation speed (N1) of the a.c. generator (1) at the idling rotation operation of the engine (2) is set to be higher than a rotation speed (Np), at which the driving torque of the a.c. generator (1) becomes a maximum (Tp). Thus, the rotation speed of the a.c. generator (1) does not changes through the rotation speed (Np) at which the driving torque of the vehicle a.c. generator (1) becomes a maximum, even when the rotation speed of the engine (2) is raised high for running of a vehicle. Thus, changes in the load applied to the engine (2) can be restricted.

In the shielding connector, a plurality of angular-shaped elastic tongue pieces 65 are provided on and projected inwardly from the upper and lower surfaces of the rear end portion of a prismatic-shaped shielding shell 60 which is so disposed as to cover a shielding wire 30 to be inserted into a housing 1; and, when the shell connecting portion 52 of a shell connecting terminal 50 is held by and between the upper and lower elastic tongue pieces 65, then they can be connected together electrically. To the shielding wire 30, there are sequentially connected the shell connecting terminal 50 and flat type male terminal 40. Since the shell connecting portion 52 of the shell connecting terminal 50 is formed in an annular shape, the shell connecting portion 52 has no insertion direction limit with respect to the elastic tongue pieces 65. Thanks to this, when connecting the flat type male terminal 40 to the shielding wire 30, there is eliminated the need to pay special attention to the connecting position of the shell connecting terminal 50 in the peripheral direction thereof. This makes it possible to simplify the terminal connecting operation.
摘要:
The present invention relates to a method and system for mobile location estimation in which range measurements between the mobile station and a base station are discriminated as being either from a base station which is line of sight with the mobile station or a base station that is non-line of sight with the mobile station (22). Non-line of sight error present in range measurements from base stations that are non-line of sight with the mobile station is corrected (24). A reconstructed line of sight range measurement is established from the correction of the non-line of sight error. The reconstructed line of sight range measurements can be used with range measurements of base stations determined to be line of sight for accurately locating the mobile station (26).
摘要:
There are provided a connector body (205) having an accommodating recess in which a pair of ferrules (203) and a pair of springs (204), respectively fitted over a pair of optical fibers (202), are accommodated, as well as a connector cover (206). The connector cover is provided with fixing pins (226,227,228), and the connector body is provided with fixing holes (215;221,222) into which the fixing pins are press fitted. A spring pressing portion (232) is provided on the connector cover for pressing the spring with a natural length in the direction toward its distal end at two positions when the fixing pins are press fitted into the fixing holes, and for holding the spring in a compressed state when the fixing pins have been press fitted. A guide taper (232a) is formed at a tip of the spring pressing portion. A pressing-portion fitting groove (233) for inserting and guiding the spring pressing portion is provided in the connector body (205).

The connector comprises a first and second connector housing, a pivotal movement member (49) mounted on the first connector housing (20) and a retaining mechanism provided between the first connector housing and the pivotal movement member (40) for holding the pivotal movement member in a fitting-starting position. The retaining mechanism includes an elastic projection (46), which is formed integrally with and projects from the pivotal movement member (40), and exends in a direction of fitting between the two connector housings, and an engagement hole (26) for receiving the elastic projection (46), which, engagement hole (26) is formed in the one connector housing, and exends in the direction of fitting between the two connector housings, wherein the elastic projection is engaged in the engagement hole (26) when the pivotal movement member (40) is disposed in the fitting-starting position. The second connector housing has an engagement release piece portion which enters the engagement hole (26) to remove the elastic projection (46) from the engagement hole (26) when the two connector housings are fitted together, whereby achieving a non-held condition.
摘要:
An ink jet ink composition and process for printing on vinyl substrates in which the ink comprises an aqueous vehicle containing at least water and a water-miscible glycol or glycol ether, wherein water constitutes no more than 80% by weight based on the total weight of the vehicle; an insoluble colorant (preferably a pigment); a polymeric dispersant; a silicon or fluorinated surfactant; and, optionally but preferably, a graft copolymer binder having a hydrophobic backbone and non-ionic, hydrophilic side chains, which binder is soluble in the aqueous vehicle but insoluble in water.
摘要:
A process for rendering carpet fiber resistant to stains and soil comprising (a) applying to carpet fiber a first aqueous medium of at least one stain resist, (b) applying to carpet fiber a second distinct aqueous medium of at least one fluorochemical soil resist, without any intervening steaming or rinsing, and (c) drying the carpet, is disclosed.
