摘要:
A material 1 to be shaped is reduced and formed by bringing dies with convex forming surfaces, when viewed from the side of the transfer line of the material 1, close to the transfer line from above and below the material 1, in synchronism with each other, while giving the dies a swinging motion in such a manner that the portions of the forming surfaces of the dies, in contact with the material 1, are transferred from the upstream to the downstream side in the direction of the transfer line.
摘要:
A pigment containing particles surface treated with N-acylglycine hydroxyaluminum and/or N-acyl-N-methylglycine hydroxyaluminum, and a pigment dispersion which contains such surface treated particles and a cosmetically acceptable oily material, having excellent dispersion stability and versatility (ease of dispersion and wide range of usage), because the particles are easily and uniformly dispersed in a short period of time at a high concentration in such a cosmetically acceptable oily material, thus a cosmetic product is thereby stable as an emulsion and has better usage than existing products.
摘要:
A pigment or extender pigment treated with a linear reactive alkylpolysiloxane having in the molecule amino groups, imino groups, halogen atoms, hydroxyl groups, or alkoxyl groups, which is oriented and adsorbed to the surface of the pigment or extender pigment by heat treatment; a process for producing the treated pigment; and a cosmetic made with the treated pigment. The alkylpolysiloxane has a degree of polymerization from 25 to 100 and a Mw/Mn ratio from 1.0 to 1.3. The organosilicon-treated pigment, characterized by silicone firmly adsorbed to its surface, freedom from residual hydrogen, very smooth feel, good adhesion to the skin, and ability to permit color pigment of fine particle size to spread well, is particularly suitable for use in cosmetics such as powder foundation, liquid foundation, rouge, and eye shadow.
摘要:
Pigments or extender pigments the surface of which are uniformly coated with hydrogenated lecithin or with the reaction product of hydrogenated lecithin and a metal salt; and a composition for make-up cosmetics containing such pigments or extender pigments and exhibiting excellent protection for the skin, resistance to wear, and good water repellency.
摘要:
In a sheet rolling mill having work rolls and backup rolls, rolling of flat sheets is facilitated by controlling constant the transverse rigidity or deflection in the direction of width of rolls. The rolling force is detected, and based on the rolling force thus detected, the value for correcting the crown of the work roll is calculated by a transverse rigidity coefficient and a function determined by sheet thickness to control the transverse rigidity.
摘要:
An emulsion slurry for cosmetic products, which comprises particles of pigments d/or extender pigments having a lipophilic moiety attached to the surface thereof and cosmetically acceptable oil component or oily material or combination of both dispersed in a liquid suspending medium comprising a mixture of water and oil.

摘要:
Longitudinal axial positions in a roll longitudinal axis of ring pistons fitted into a profile-variable rolling roll are detected with a higher degree of accuracy. In response to outputs representative of the detected longitudinal axial positions of the ring pistons, the positions of the ring pistons can be controlled with a high degree of accuracy, whereby controllability of shape of the rolling roll is enhanced.
摘要:
Disclosed is a hydraulic servomechanism including a control loop consisting of an input device, an adder-amplifier, a servovalve, a cylinder or actuator and a load operatively connected in the order named for controlling the position of the load, a position feedback loop and an acceleration feedback loop. In one embodiment of the invention, the hydraulic servomechanism further includes a feedback loop wherein an output from an accelerometer or pressure sensor for detecting a differential pressure across a piston in the cylinder and an error signal from the adder-amplifier are arithmetically processed and fed back to the adder-amplifier. In another embodiment, the hydraulic servomechanism further includes an additional feedback loop wherein an output from a two-input adder to which are applied a signal representative of a supply pressure of working oil to be delivered from the servovalve to the cylinder and a signal representative of a pressure difference across a piston of the cylinder is arithmetically processed and fed back to a divider inserted between the adder-amplifier and the servovalve. In both embodiments, shocks are substantially eliminated in a hydraulic system.
摘要:
A rolling mill wherein a pair of upper and lower work rolls are rotated at different peripheral velocities with the peripheral velocity ratio being substantially equal to an elongation ratio at which a sheet metal is rolled, and the tensions exerted to the sheet metal entering and leaving the pair of work rolls are controlled in such a way that the velocity of the sheet metal entering the work rolls may be maintained equal to the peripheral velocity of one of the pair of work rolls which is rotated slower than the other while the velocity of said sheet metal leaving the work rolls may be maintained equal to the peripheral velocity of said the other work roll. Rolling may be accomplished without the need of wrapping the sheet metal around the work rolls, and the rolling pressure may be reduced to a degree comparable RD process.
