摘要:
A channel switching valve is disclosed. The channel switching valve has a stator and a body section each having a connecting surface. The stator and the body section are removably fixed to each other by bolts at their connecting surfaces. Each of the connecting surfaces has a protruding/recessed pattern formed thereon, and the patterns are designed to fit into each other. By rotating the stator and the body section relative to each other, the stroke of a spring is changed between a position where the protruding/recessed patterns of the stator and the body section are fitted into each other and a position where they are not fitted into each other. The spring is held in the body section in its compressed state to urge the rotor toward the stator. An urging force for pressing the rotor against the stator is adjusted by changing the stroke of the spring.
摘要:
This invention provides a display apparatus, control method, and control program, which display hue differences and color difference values of respective patches as lists, and display the hue direction of the hue difference of each individual patch on a chromaticity diagram in an easy-to-understand manner. To accomplish this, a display method of this invention includes a specifying step of specifying a color determined by a hue difference calculated from first and second values associated with spectral reflectance characteristics, and a display step of displaying the color specified in the specifying step as a graphical object. The specified color is specified as a representative color that indicates a hue on a chromaticity diagram to which the hue difference biases.
摘要:
A toner composition including toner particles, wherein the toner particles are prepared by a method in which toner constituents including at least a binder resin and a colorant are kneaded upon application of heat to prepare a toner constituent mixture; the toner constituent mixture is dissolved or swelled in an organic solvent capable of dissolving or swelling at least the binder resin to prepare an oil phase liquid; the oil phase liquid is emulsified in an aqueous liquid to prepare an emulsion; the emulsion is coagulated; and then the coagulated emulsion is dried to prepare the toner particles.

In a preferred embodiment, a channel switching valve has a stator having a connecting surface and a body section having a connecting surface, and the stator and the body section are removably fixed to each other by bolts at their connecting surfaces. Each of the connecting surfaces has a protruding/recessed pattern formed thereon, and the protruding/recessed patterns are designed to be fitted into each other. By rotating the stator and the body section relative to each other, the stroke of a spring is changed between a position where the stator and the body section are fixed to each other in a state where their protruding/recessed patterns are fitted into each other and a position where the stator and the body section are fixed to each other in a state where their protruding/recessed patterns are not fitted into each other. The spring is held in the body section in its compressed state to urge the rotor toward the stator. An urging force for pressing the rotor against the stator is adjusted by changing the stroke of the spring.
