摘要:
The surface-coated optical fiber of the invention is composed of a fibrous body of a vitreous material, e.g. fused quartz glass, and a coating layer thereon formed of a coating composition comprising an organosiloxane-modified organic polymer, of which the backbone is formed of recurring organic units such as a polybutadiene, an acrylic polymer and the like having modifying pendant groups containing an organosiloxane unit. The workability of the coating composition in the coating application is excellent so that a high uniformity is obtained in the coating layer in comparison with a coating composition comprising an unmodified organic polymer. The coating layer thus formed has a remarkably improved mechanical strength over a coating layer formed of an organopolysiloxane resin alone.

A shift register which is formed by a memory, the number of shift stages of the shift register is determined by the count value of a counter and designating a read address of the memory by a value obtained by subtracting an arbitrary constant from the count value of the counter through an operator. A multiplexer is provided at the input side of the operator. Output data, obtained by selecting a constant for determining the number of shift stages of the counter and a scan address in accordance with a scan enable signal, are provided to the operator. When the constant for determining the number of shift stages of the counter is input, the operation of the shift register is carried out and when the scan address is input, the content of each stage of the shift register is scanned out.

The present invention relates to a binder composition for making self-hardening foundry molds that is capable of improving the hardening speed of the molds and the strength of the molds, and is excellent in storage stability; and a method for producing a foundry mold, using this composition. The binder composition for making self-hardening foundry molds of the present invention is a binder composition for making self-hardening foundry molds, comprising a furan resin and an ion compound, wherein the ion compound contains at least one anion selected from the group consisting of a hydrogensulfite ion, a sulfite ion, a pyrosulfite ion, a thiosulfate ion, a thionate ion, and a dithionite ion; the content of the anion is from 0.006 to 0.60 parts by weight for 100 parts by weight of the furan resin; and the composition has a pH of 6 or less at 25° C.
摘要:
An image forming apparatus includes an image bearer to bear a black toner pattern formed with a black toner image under an increased exposure amount and an increased developing bias. A first optical sensor detects an amount of reflection light reflected by the black toner pattern on the image bearer. The first optical sensor includes a light-emitting element to emit light toward the black toner pattern on the image bearer and a light-receiving element to receive the reflection light reflected by the black toner pattern on the image bearer. A toner adhesion amount converter converts the amount of the reflection light detected by the first optical sensor into a toner adhesion amount of toner adhered to the image bearer and adjusts an image density according to the toner adhesion amount.

An image forming apparatus includes a developer bearer and a toner pattern bearer rotatable in a given direction of rotation to bear an adjustment toner pattern formed with the developer bearer. A toner pattern detector detects an amount of reflection light reflected by the adjustment toner pattern on the toner pattern bearer. A controller performs an adjustment mode to convert the detected amount of reflection light into a toner adhesion amount of toner of the adjustment toner pattern adhered to the toner pattern bearer. The controller forms an adhesion amount suppressing toner image on an upstream region on the toner pattern bearer that is upstream from the adjustment toner pattern in the direction of rotation of the toner pattern bearer. The upstream region is defined by a circumferential length of the developer bearer in the direction of rotation of the toner pattern bearer.

摘要:
An ozone generator generates ozone gas; a gas-liquid mixer mixes the ozone gas and a liquid; a liquid storage tank separates an introduced gas-liquid mixture into gas and a liquid; a circulation path circulates gas among the ozone generator, the gas-liquid mixer and the liquid storage tank; and an opening and closing control means controls a flow of gas flowing out through a gas outlet port of the liquid storage tank in accordance with a stored liquid amount in the liquid storage tank. As a result, the stored liquid amount of the liquid stored in the liquid storage tank can be adjusted.
