摘要:
An object of the present invention is to provide a base generator which has sensitivity and is applicable to a wide range of applications, and a photosensitive resin composition which is applicable to a wide range of applications due to the structure of a polymer precursor in which reaction into a final product is promoted by a basic substance or by heating in the presence of a basic substance. The base generator generates a base by exposure to electromagnetic radiation and heating. The photosensitive resin composition comprises a polymer precursor in which reaction into a final product is promoted by the base generator and a basic substance or by heating in the presence of a basic substance.

A printer has a main unit supporting one of a platen roller and a recording head and has a movable blade, a movable blade holder holding the movable blade, a reciprocating mechanism for reciprocating the movable blade holder to slide the movable blade, a drive gear that drives the reciprocating mechanism, a motor that rotationally drives the drive gear, and a gear train mechanism that transmits a rotational force of the drive gear to the reciprocating mechanism. A detachable unit supports the other of the platen roller and the recording head and has a fixed blade for cutting the recording sheet in association with the movable blade. The detachable unit is attachable to and detachable from the main unit and moves close to and away from the main unit along a sliding direction of the movable blade when the detachable unit is attached to and detached from the main unit.

The present invention is directed to an infrared lens that ensures sufficient quantity of light incident on light receiving elements so as to produce a clear infrared picture. The infrared lens comprises a first or leading lens unit of positive refractivity closer to an object, and a trailing lens unit. The trailing lens unit consists of at least a second group of lens pieces located closer to an imaging plane than the first lens unit, and a third group of lens pieces located closer to the imaging plane than the second group of lens pieces. The trailing lens unit is displaced in any direction perpendicular to the optical axis for compensating for image vibration.

A plurality of first oil passageways are recessed in an annular projected portion of a bearing cup of a cross shaft joint, each first oil passageway communicating with inner and outer periphery sides, and being increasing in groove width gradually from the outer periphery side toward the inner periphery side. A plurality of second oil passageways are recessed in the annular projected portion, and each second oil passageway is disposed between the first oil passageways, and communicates with the inner and outer periphery sides, and is decreasing in groove width gradually from the outer periphery side toward the inner periphery side. When the bearing cup is angularly moved relative to a cross shaft, grease in the first oil passageways is flowed from the outer periphery side of the annular projected portion to the inner periphery side thereof, while grease in the second oil passageways is flowed from the inner periphery side of the annular projected portion toward the inner periphery side.

To provide a sheet material cutting unit which can retain the posture of a sheet material when the sheet material is cut such that a movable blade can bite the sheet material with stability. A sheet material fixedly holding portion provided in parallel with a fixed blade and a sheet material movably holding portion linked with a movable blade are provided downstream from a sheet material cutting position in a sheet material transfer direction to retain a sheet material from both sides of the sheet material when the sheet material is cut.

According to the invention, there is provided a tapered roller bearing in which, where D represents a larger end diameter of the tapered roller and L represents a roller length thereof, the roller length L is 18 mm or smaller, and a ratio of the large end diameter and the roller length of the tapered roller which is expressed by D/L is in the range of 0.55 to 0.9. In addition, respective raceway surfaces of the outer ring and the inner ring and rolling contact surfaces of the tapered rollers are crowned, and a total crowning amount is set to be 50 μm or larger, an outer ring crowning rate is set to be 40% or larger, and a roller crowning rate is set to be 20% or smaller.

A printer has first and second units configured for attachment/detachment relative one another and for supporting one of a recording head and a platen roller. The first unit has spaced wall portions provided with first and second recesses. The second unit has engagement pins that detachably fit into respective ones of the first recesses, a latch member that undergoes rotation about an axial line of the engagement pins and has a pair of lock pins that detachably fit into respective ones of the second recesses after the engagement pins are fitted in the first recesses, a biasing member biasing the latch member in a first direction of detachably fitting the lock pins in the second recesses, and a release member for moving the lock pins in a second direction opposite to the first direction to detach the lock pins from the second recesses.

The present invention is directed to an infrared zoom lens that has one or more of its lens pieces made of chalcogenide tractable in processing such as press-molding, grinding, and the like, so as to facilitate compensating for spherical aberration that is generally hard to do, thereby producing a clear and vivid image. The infrared zoom lens has first to fourth lens elements arranged in series from the foremost position closest to the object; each of the first to fourth lens elements being of a single lens piece, and at least one of the first to fourth elements is made of chalcogenide.

Provided is a printer with a cutter, which is capable of separating a main unit and a detachable unit while a movable blade is automatically restored even when the movable blade is stopped halfway through sliding, and regulating the slide of the movable blade at a time of separation of both the units, to thereby increase safety. Provided is a printer with a cutter including: a main unit (10) incorporating a movable blade (8); and a detachable unit (11) incorporating a fixed blade (9) and being separably combined with the main unit, the main unit including: a movable blade holder for holding the movable blade; a reciprocating mechanism for causing the movable blade holder to reciprocate along with rotation of a drive gear (82); a biasing member for biasing the movable blade in a direction of separating the movable blade from the fixed blade; and a gear train mechanism (90) for coupling the drive gear and the reciprocating mechanism to each other when the detachable unit is combined, and for disconnecting the drive gear and the reciprocating mechanism from each other when the detachable unit is separated, the detachable unit moving close to and away from the main unit along a sliding direction of the movable blade.
