In a control method for an ink jet recording apparatus with which an amount of head generated by the head is restricted when a condition of a head temperature being not lower than a predetermined threshold is found includes the steps of detecting the head temperature and an environment temperature around the head, and restricting an extent of the amount of head generated by the head depending on the environment temperature or a difference between the head temperature and the environment temperature.

In an ink-jet apparatus employing an ink-jet head having a plurality of heaters corresponding to one ink ejection opening, appropriate preliminary ejection is performed per each ejection amount mode set by a heater to be used among a plurality of heaters. Depending upon a set printing mode, printing is performed in one of large, medium and small ejection amount modes. For example, after printing is performed for a predetermined amount by the small ejection amount mode, preliminary ejection during printing is performed in the medium ejection amount mode which is greater in ejection amount than the small ejection amount mode. By this, the interval between preliminary ejections during printing can be set to be longer to prevent lowering of throughput due to the preliminary ejection operations.

An ink jet printing method for performing printing onto a printing medium with the use of both of a colored ink ejected from an ink jet head and a printing property improving liquid to be applied to the printing medium for improving a printing property for an ink jet printing apparatus, having the steps of: at least one time or more printing a first colored ink on the printing medium, at least one time or more applying the printing property improving liquid onto a region printed with the colored ink, and at least one time or more printing a second colored ink on a region where the printing property improving liquid is applied.
摘要:
An ink jet printing method prints an image on a printing medium by ejecting ink and printabilty improvement liquid containing a substance for improving printablity of the ink to the printing medium. At this time, ejection of the ink and ejection of the printability improvement liquid onto the printing medium are achieved such that the position where the printability improvement liquid is applied and the position where the ink is applied are different from each other, but partially overlap when the ejected printability improvement liquid comes into contact with the ejected ink on the printing medium.

An optical fiber includes a core, a first cladding, a second cladding, and a third cladding. The core has a refractive index n.sub.0. The first cladding is formed around the core and has a refractive index n.sub.1. The second cladding is formed around the first cladding and has a refractive index n.sub.2. The third cladding is formed around the second cladding and has a refractive index n.sub.3. The refractive indices have relationships n.sub.1 >n.sub.2 >n.sub.3 and n.sub.1 >n.sub.0.
摘要:
Antitumor agent which comprises as the principal agent a mixture of organic compounds having amino group and silyl group (reffered to as silamines) and represented by structural formulae with Adriamycin. Use of silamines in the form of a mixture with Adriamycin, which is an anti-cancer agent showing a potent effect but having extremely serious side effects, makes it possible to highly potentiate the anti-cancer properties of Adriamycin. As a result, the dose of Adriamycincan be reduced and thus its side effects can be relatively relieved as compared with the case where it is used alone. ##STR1## �wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7 and R.sub.8 represent each hydrogen or C.sub.1-10 alkyl, aryl or aralkyl, or the pair of R.sub.1 with R.sub.2 and that of R.sub.5 with R.sub.6 may be bonded via alkylene, allylene or aralkylene.!
摘要:
There is disclosed an evaluating apparatus for evaluating a manipulation performance of a commodity with operating parts. Three dimensional position and orientation of a first body like an operator's fingertip is detected to virtually display the first body. Also, configuration and functions of operating parts planned to be attached to a commodity are set, and three dimensional position and orientation of a second body like a commodity model having the same external shape as that of the commodity is detected to virtually display the commodity with the operating parts. When a planned area of the second body is manipulated by the first body, a contact of the second body with the first body is detected, and an operating part Po placed at a position corresponding to the planned area is detected. Thereafter, the operating part Po of which an external shape is virtually changed by the manipulation of the first body is displayed according to the configuration and function of the operating part Po. Accordingly, an operator can actually feel a state that the external shape of the commodity is changed when the operator virtually manipulates the commodity, without making the commodity on an experimental basis.

##STR1## (wherein R 1 and R 2 independently stand for at least one member selected from the class consisting of alkylene groups, substituted alkylene groups, cycloalkylene groups, substituted cycloakylene groups, arylene groups, and substituted arylene groups), is a novel diacetylene-nylon salt compound possessing two kinds of ability of solid-state polymerization, and two-dimensional macromolecular crystals are obtained by severally polymerizing the diacetylene moiety and the nylon salt moiety of the compound. A shaped article of hig rigidity is produced by filling a mold with the aforementioned salt and subjecting the salt in the mold to simultaneous application of heat and pressure.

A wheel bearing assembly for an automotive wheel equipped with a detector for the number of revolutions of a wheel hub. It has an outer member and two inner members mounted in the outer member through rolling elements. A pulse ring in the form of a multipolar magnet is mounted in the bearing assembly so as to be fixedly held in annular grooves formed in the outer periphery of the inner members at their abutting ends or to be supported on one of the inner members. A sensor including a Hall IC is mounted in the outer member at such a position as to face the pulse ring. The pulse ring rotates with the inner members to allow the sensor to detect the rotational speed of the wheel.
