摘要:
The present invention provides a method for manufacturing a dynamoelectric stator enabling coil ends to be impregnated with varnish simply and to a high fill factor by adjusting varnish viscosity at a temperature of a stator during varnish application to a predetermined range. The configuration includes a varnish treatment process including: a preheating process in which the stator is preheated; a varnish application process in which a varnish adjusted so as to have a viscosity of 16 to 105 mPa·s at a temperature of the stator during varnish application is dripped onto a coil end from radially outside the stator while rotating the preheated stator around a central axis; and a varnish heat hardening process in which the varnish is hardened by heating the stator to which the varnish has been applied. In this manner, a stator can be manufactured in which coil ends are impregnated with varnish to a high fill factor, improving the electrical insulation properties and the galvanic corrosion resistance of the stator winding, and also increasing the overall rigidity of the stator.

A method for varnish application to a dynamoelectric stator is disclosed. The method includes a varnish treatment process and application by preheating the stator; adjusting a viscosity of the varnish; dripping the varnish onto a coil end of the stator from radially outside the stator while rotating the preheated stator around a central axis; and hardening the varnish dripped onto the coil end by heating the stator. The varnish viscosity is adjusted so that said varnish dripped onto said coil end passes through the coil end from radially outside to radially inside, and the varnish is dripped onto said coil end along a direction which is perpendicular to the central axis of the collective coils.

An image forming apparatus includes a conveyance device to convey a recording medium in a first direction and a second direction opposite the first direction; an image forming device; an imaging device; and circuitry to control the image forming apparatus. Controlled by the circuitry, the image forming device forms the colorimetric pattern on the recording medium that has been conveyed in the first direction by a predetermined distance after the marker pattern is formed. Controlled by the circuitry, after the colorimetric pattern is fixed, the circuitry causes the conveyance device to convey the recording medium in the second direction by an amount equivalent to a distance from the marker pattern to an imaging position by the imaging device plus a margin, conveys the recording medium in the first direction until the imaging device detects the marker pattern, and conveys the recording medium in the first direction to a colorimetry position.

An apparatus includes: a light source; a two-dimensional image sensor that receives reflected light from a subject including specular light of the source and outputs an image of the subject; and an optical member arranged in an optical path of light emitted from the source to the subject. When a specular position of the source in the subject arranged apart from the two-dimensional image sensor by a certain distance is defined as a first specular position, whereas a specular position of the source in the optical member is defined as a second specular position, a relative positional relation of the optical member and the source with respect to the two-dimensional image sensor is determined so that a difference between an incident angle from the source toward the first specular position and an incident angle from the source toward the second specular position is a reference value or more.

A lead frame (100) for a semiconductor device is formed by applying nickel plating (102), palladium plating (103), and gold flash plating (104) substantially entirely to lead frame body (101) such as copper thin plate in this order, and further applying silver plating (105) selectively to part of an inner part that is to be enclosed with a package of the semiconductor device. The lead frame (100) may also include a base of the package. The silver plating contributes to an excellent light reflectance and wire bonding efficiency of the inner part, whereas the gold flash plating contributes to an excellent resistance to corrosion and soldering efficiency of an outer part that is outside the package.
摘要:
It is intended to provide a modified DNA or RNA, the cytoplasmic localization of which has been established, and an siRNA, which is localized in the cytoplasm, shows a high activity and, therefore, is appropriately usable as a genetic drug, by using a means generally applicable to DNAs of various types regardless of original tissues. A cytoplasmic localization DNA or RNA modified with a peptide can be constructed by modifying a DNA fragment with an active hydrogen-containing group on a solid support, fusing a peptide having an active hydrogen-containing group therewith and then removing from the solid support. On the other hand, a cytoplasmic localization siRNA can be obtained by introducing chemical modification group(s) into the 5′-terminus of at least one of the sense chain and the antisense chain constituting the double-strand, or a dangling end of the antisense chain, or both of them.
