摘要:
A stencil printing ink container includes an ink container body. An ink charge port is provided in an end wall of the ink container body and an inner plug is mounted on the ink charge port. The inner plug is provided with an ink discharge port smaller in the outer diameter than the inner diameter of the ink charge port and gives an ink suction nozzle of an ink pump access to the ink discharge port.

A piston-type ink container is inserted into an ink container holder of a stencil printer so that an ink suction nozzle of the stencil printer is fitted in a small diameter portion of the ink container to suck the ink in the ink container through an ink discharge port on the tip of the small diameter portion. A vacuum release mechanism at least partly releases vacuum in the space evacuated by the ink suction nozzle before the tip of the nozzle and the tip of the small diameter portion are aligned with each other when the ink container is drawn from the ink container holder.
摘要:
An ink container includes an ink container body and a memory attached to the ink container body for storing predetermined information. The memory is bonded to a part of the surface of the ink container body at its surface opposed to the surface of the ink container body over an area not larger than 90% of its surface facing toward said part of the surface of the ink container body.

Disclosed is a laser light source apparatus. The laser light source apparatus includes a pumping light source and a pair of resonator mirrors. In the laser light source apparatus, the pumping light source includes at least a laser medium and a wavelength conversion element, and the laser medium is pumped by light having a multi-transversal mode pattern and the wavelength conversion element are irradiated with a line beam of fundamental wave obtained by the oscillation by the laser medium to output a line beam of converted wave. The laser light source apparatus further includes at least one reflector bending light path is provided in the resonator such that a longitudinal direction of the line beam of fundamental wave is approximately perpendicular to an incident plane of the reflection unit.
摘要:
A locus interpolation device characterized in that the device is attached to an end of a wrist of a movable structure such as a robot, with a tool supported by the device, and a circular or noncircular locus is interpolated by controlling the operation of the tool independently from that of the movable structure.

An elongate molding member for automobile body components and the like, as well as a method of producing such molding members are disclosed. The molding member (11) includes a core element (12), and a cover element (13) made of synthetic resin material co-extruded about the core element (11). The core element (11) has a strip-like ornamental portion (15) which is different in color from the synthetic resin material of the cover element (13) and is to be disclosed outside by removing a separable portion (18) defined by at least one longitudinal slit (17) in the cover element (13). The ornamental portion (15) of the core element (12) has a longitudinally variable width (W.sub.1, W.sub.2) to provide an aesthetically refined appearance and to thus satisfy various ornamental design requirements.
摘要:
Novel phosphorsulfide derivatives of deoxynucleosides or deoxynucleotides are provided, which have the general formula: ##STR1## wherein R.sup.1 is a hydroxy-protecting group; R.sup.2 is a phosphate-protecting group; R.sup.3 is an aryl group; B.sub.1 and B.sub.2 may be the same or different and each are a base residue which may have a protecting group; and n is zero or a positive integer, provided that if n is 2 or larger, the respective R.sup.2 may be the same or different. They are prepared by reacting a deoxynucleoside or deoxynucleotide with a 1,2,4-triazolylphosphine compound and are useful as intermediates for the preparation of oligodeoxy-nucleotides.
