摘要:
A thermal head driving method of driving thermal heads is disclosed. The method includes a step of dividing the thermal heads into plural groups, providing for each of the groups a common potential terminal, a step of using a drive circuit to drive the thermal heads of one or more of the groups, and a step of applying an operating voltage to the common potential terminal of said one or more groups driven by the drive circuit.

A printing apparatus having shorter length in the longitudinal direction and a dust-protecting feature is disclosed. The printer includes a main frame, a subframe assembly, first and second pulse motors each have a reduction gear drive mechanism, a thermal head, a platen roller, a rotary blade, and a stationary blade. The first motor for driving the platen roller and the second motor for driving the rotary blade are disposed between two side plates provided one on each end of the main frame. The reduction gear drive mechanisms are substantially sealed and disposed inside the corresponding side plates. Two pulleys and a timing belt are provided outside each of the side plates.

The present invention provides pharmaceutical formulations suitable for intravenous injection comprising a lyophilized anti-ulcerative agent reconstituted in isotonic solutions suitable for intravenous administration, such as 5% dextrose or 0.9% sodium chloride. The solutions are brought to a pH of between about 9 and about 12, preferably between about pH 10 and 11, by a glycine-sodium hydroxide buffer. Such formulations are chemically and physically stable, and do not significantly change color, for at least between about 6 and about 12 hours at room temperature, and are stable to color change for from between about 24 and 48 hours if kept at 5° C.

Active ingredients such as medicines are mixed with excipient and then kneaded together with binder and solvent such as alcohol or water to prepare a wetted paste. A mold is filled with this paste. Top and bottom surfaces of the paste within the mold are coated with powder such as lubricant in order to avoid possible sticking of the paste to the apparatus during a subsequent compression step. Then a compressive pressure is exerted on the surface of the paste. Thereafter, the tablet is taken from the mold. The molded tablet can contain water-soluble or fat-soluble medicine.

A hydraulic tensioner 10 includes a piston rod 12 slidably fitted in a cylinder 14 with a small gap or clearance therebetween, and a housing 16 containing the cylinder 14. A ball seat 20 is press-fitted in an end of the cylinder 14 opposite to the piston rod 12 so as to define within the cylinder 14 a high pressure oil chamber 21. The housing 16 has a partition wall 26 at a substantially central portion thereof. The cylinder 14 is loosely fitted in the housing 16 with its longitudinal portion extending forwardly from the partition wall 26. The partition wall 26 has an oil passage 32 having an inside diameter smaller than the outside diameter of the ball seat 20, so that the cylinder 14 and the ball seat 20 are in abutment with the partition wall 26 of the housing 16. A force tending to retract the piston rod 12 generates a pressure which acts on the partition wall 26 either directly via a spring 24 and the cylinder 14 or via the high pressure oil chamber 21 and the ball seat 20.
摘要:
An object of this invention is to present a thermal printer for printing at high speed the data with the drive at a low voltage of around 5 V while preventing the printing problems attributable to the voltage drop due to internal impedance and to the loss inside the head coming from the common conductor inside the head. The thermal printer has a plurality of heating elements.The thermal printer comprises a print head consisting of the print blocks which have divided the heating elements at every stipulated quantity and a heating means for electrically heating the heating elements on the basis of the stipulated data at every print block wherein the heating means has been structured to simultaneously heat the heating elements against a plurality of print blocks to color the thermosensitive paper in contact with the heating elements of the print block.

A conjugate formed by the covalent bonding of a prostaglandin or a similar compound thereto and a polysaccharide. The prostaglandin is selected from prostaglandin E1, prostaglandin E2, prostaglandin F2.alpha., prostaglandin I2, carbacycline and iloprost and the polysaccharide is selected from pluran, amylose, amylopectin, cellulose, dextran and hydroxyethylated starch.
摘要:
A three-dimensional object imaging method is implemented on a computer for imaging an object. The three-dimensional object imaging method includes the steps of irradiating ultrasonic waves having two mutually different frequencies on the object which is to be imaged, measuring sound pressures of scattering waves from the object so as to obtain two acoustical holography images thereof, and obtaining a three-dimensional shape of the object based on a phase error between the two acoustical holography images.
