摘要:
An electronic instrument is adapted to communicate with another electronic instrument. The electronic instrument includes an acquisition section, a storage section, an inquiry section and a processing section. The acquisition section is configured to acquire identification information from a managed article used by the electronic instrument, the identification information being read-only information uniquely assigned to the managed article. The storage section is configured to store the identification information acquired by the acquisition section. The inquiry section is configured to inquire another electronic instrument as to whether the identification information acquired by the acquisition section is already stored in another electronic instrument. The processing section is configured to perform processing in response to a result of inquiry by the inquiry section.
摘要:
A central processing unit sets which of the following modes a data processing device is to operate in accordance with a user program. The high-speed operation mode allows operation within a first range in which an external supply voltage is relatively high. The wide voltage range operation mode allows operation within a second range in which the external supply voltage includes the first range and a relatively low voltage range, and an upper limit of a frequency of the first clock in the wide voltage range operation mode is lower than an upper limit of a frequency of the first clock in the high-speed operation mode. The frequency of the first clock in the low power consumption operation mode is lower than the frequency of the first clock in the high-speed operation mode and the frequency of the first clock in the wide voltage range operation mode.

A thin and highly transparent coating having excellent air tightness, adhesion to a substrate, lubricating properties, galling resistance, and corrosion resistance is formed on the surface of a metal substrate and particularly on the surface of a threaded joint which is used for connection of oil country tubular goods. A photocurable composition comprising (A) a photocurable (meth)acrylate resin, (B) a (meth)acrylate monomer selected from a monofunctional (meth)acrylate monomer and a difunctional (meth)acrylate monomer, (C) a trifunctional or higher multifunctional (meth)acrylate monomer, (D) a photopolymerization initiator, (E) a benzotriazole anticorrosive agent, (F) an anticorrosive pigment selected from a phosphate anticorrosive pigment and calcium ion-exchanged silica, and (G) a phosphate ester is used to form a photocured coating.
摘要:
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).
摘要:
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.
