A cartridge includes a casing, a printing material containing portion, a printing material flow path and first and second insertion holes formed in a front face of the casing. A rod used for detection of the out-of-printing material state is inserted into the first insertion hole, and a printing material supply tube is inserted into the second insertion hole. The first insertion hole is located on the front face at a middle position between a first side face and a second side face of the casing.

A threaded joint for steel tubes has a contact surface (30) including a threaded portion and a non-threaded metal-to-metal contact portion. The contact surface of at least one of a pin and a box of the joint is coated with a first plating layer (34) made of a Cu—Zn alloy or a Cu—Zn-M1 alloy (wherein M1 is at least one element selected from Sn, Bi, and In). An undercoat (32) of one or both of a Ni plating layer (32a) and a Cu plating layer (32b) and an overcoat of a Sn-M2 alloy plating layer (36) (wherein M2 is one or more elements selected from Bi, In, Ni, Zn, and Cu) may be formed below and above the first layer, respectively. A solid lubricating coating (38a) and a viscous liquid or semisolid lubricating coating (38b) may also be formed atop the plating layer as a lubricating coating (38).

A liquid ejection apparatus including an ejection head having a nozzle in which liquid is ejected through the nozzle, a plurality of cartridges that retain the liquid and supplies the liquid to the ejection head, and a switching mechanism that switches liquid to be supplied to the ejection head from a plurality of types of liquid supplied from the cartridges. The switching mechanism includes a body having a communication passage in communication with the ejection head, a first diaphragm chamber and a second diaphragm chamber that communicate with each other through the communication passage and located to facing each other, a first diaphragm and a second diaphragm arranged in the first diaphragm chamber and the second diaphragm chamber, respectively, and capable of opening and closing the communication passage, and an operation mechanism provided in the communication passage. The operation mechanism includes a first operation end and a second operation end that operate the first diaphragm and the second diaphragm, respectively, when the communication passage is opened to allow communication between at least one of the first and second diaphragm chambers and the ejection head, and an urging member that urges the first and second operation ends in a direction in which the communication passage is opened by the first and second diaphragms.

The present invention provides an image coding apparatus and an image coding program that execute quantization control so that a generating bit is made close to a target bit. The image coding apparatus according to the present invention includes a generated bit measurement unit, a target bit setting unit, a residual bit computing unit for computing a residual value between the generated bit and the target bit, a remaining video buffer capacity measurement unit, and a quantization parameter computing unit for computing a quantization parameter to set the same to the quantization unit. The quantization parameter computing unit computes a quantization parameter for next image data to be encoded on the basis of at least one of the residual value computed and the remaining video buffer capacity measured.

Whether mail transmitted is unwanted mail is discriminated even in a case where the mail is transmitted from a zombie PC is determined by an unwanted mail discriminating apparatus. The unwanted mail discriminating apparatus has a mail receiver for receiving e-mail; an information extractor for extracting discrimination information for discrimination on whether or not unwanted mail, from the e-mail received; a reliability evaluating part (a sender information reliability evaluator and a URL information reliability evaluator) for connecting to a reliability evaluation database storing information corresponding to the discrimination information, which is for evaluating reliability of the discrimination information, and for evaluating the reliability of the extracted discrimination information with reference to the information stored in the reliability evaluation databases; and a discriminator for discriminating whether the received e-mail is unwanted mail, based on the reliability of the discrimination information evaluated.
