Abstract: An image forming apparatus counts a number of sheets to be printed with a limited number of colorants or a limited amount of colorant using an other counter that is provided other than a color counter and a monochrome counter. The counter value of the other counter is adjusted using a weighting factor before being added to or subtracted from a counter value of the color counter or the monochrome counter.

Abstract: A printing system including a plurality of host devices and a plurality of printing devices connected. The printing system includes: a storage unit; a first storage processing unit for storing, in the storage unit, a print status of a print job; an information updating unit for monitoring the plurality of printing devices and updates the execution status identification information stored in the storage unit; and a job management unit for determining, based on the print status, whether the print job is to be executed on the one printing device. When a processing request for the print job is sent from another host device while the printing process for the print job sent from the one host device is suspended in the one printing device, the job management unit allows the one printing device to execute the print job sent from the another host device.

Abstract: A time limit for a printer to be restored to a printable state after an occurrence of a print error that prevents the printer from printing is variably set. If the printer is not in a printable state when an elapsed time since the print error occurred in the printer reaches the time limit being set or exceeds the time limit, a print start command is transmitted to another printer, and a job assignment is switched to the other printer.

Abstract: An image forming apparatus prints images of different document sizes on paper having a predetermined paper size. The image forming apparatus includes a computation processing part to compute a print position of the image with respect to the paper, based on the document size, the paper size and moving amount computation information that is input thereto, and a print processing part to arrange and print the image on the paper, based on the print position computed by the computation processing part.

Abstract: An image forming apparatus, a client PC, and a thin client PC are connected to a server device via a network. The client PC, or the thin client PC, transmits a printing instruction to the server device and the server device transmits the printing instruction to the image forming apparatus. In a thin client environment, a network between the server device and the image forming apparatus can be a narrowband network. Therefore, the server device compresses the whole printing instruction and then transmits the compressed printing instruction to the image forming apparatus.

Abstract: Titanium dioxide powder with a greatly decreased volatile moisture content can be obtained by surface treating with titanium dioxide powder with addition of a calcium salt and/or a silane coupling agent, or by a surface treatment by addition of an aluminate together with these surface treatments. A masterbatch containing this titanium dioxide powder is of high quality, having no defect due to foam generation upon high temperature processing.

Abstract: To hydrous titanium dioxide obtained by hydrolysis of titanium sulfate was added a predetermined amount of a water-soluble aluminum compound and/or a water-soluble zinc compound, the mixture is calcined, and a suitable amount of aluminum and/or zinc is introduced into the crystals to make up the crystal defects of anatase-type titanium dioxide, so that it has increased stability and excellent color stability.

Abstract: Diamond bur A has base metal 1 formed with cylindrical shank 1b on one side of diamond bur A, and cutting portion 1a formed on base metal 1 on the other side of diamond bur A extending over a given length from an end of diamond A. A mixture 2 of various abrasive grains with three different grain sizes are secured to cutting portion 1a. Since various abrasive grains with different grain sizes are secured to cutting portion 1a, with the increase of load applied on artificial tooth, the number of abrasive grains contributing to cutting increases, and the machinability is improved. This tendency is equal to the machinability of the diamond bur on the market for cutting human dentin, or dental enamel.

Abstract: The invention provides a method of quantitating reticulocytes with high sensitivity and high accuracy at low cost employing a fluorescent dye suitable for the staining of reticulocytes. A blood sample stained with a fluorescent dye composition containing TOTO-3, TO-PRO-3, POPO-3, PO-PRO-3, YOYO-1, YO-PRO-1, YOYO-3 or YO-PRO-3 as the fluorescent dye is exposed to light in the red-wave length region in the case of TOTO-3 or TO-PRO-3, light in the green region for POPO-3 or PO-PRO-3, light in the blue region for YOYO-1 or YO-PRO-1, or light in the orange region for YOYO-3 or YO-PRO-3 and the resultant fluorescent emission from the blood sample is measured to enumerate reticulocytes.

Abstract: In a flame detector having an optical head, a plurality of light-taking optical fibers are arranged so as to provide different directions of fields of vision at their front ends. Therefore, the watching regions of burner flame has been widened, and even if the primary combustion zone moves back and forth with respect to the tip of the burner due to the change in load, the flame can be accurately detected providing high reliability. Junction optical fibers and wiring optical fibers are separately provided in addition to the light-taking optical fibers. Therefore, when one or more optical fibers are damaged, only the damaged optical fibers are required to be replaced with new ones providing cost reduction in maintenance. Two or more photosensitive elements having different sensitive wavelength regions are used. Therefore, various types of flames having various wavelengths can be effectively detected providing wider detection range when compared with conventional apparatus.

Abstract: Processes for producing an oligoester and producing unsaturated polyester resin by use of the oligoester using unsaturated dibasic acid or its anhydride and isophthalic acid as dibasic acid components, and propylene oxide as a polyol component, characterized by (a) the step of reacting isophthalic acid with propylene oxide in the presence of an amine compound catalyst to form an oligoester, (b) the step of removing volatile components from the oligoester by heating it at a temperature range of 180.degree.-300.degree. C., (c) the step of treating the resulting oligoester with silica-alumina compound having adsorbing property, and (d) the step of reacting the oligoester so treated with the unsaturated dibasic acid or its anhydride.
