An information processing device is provided. The information processing device includes a frame acquiring unit for acquiring a frame using a signal transmitted via a network, a computing unit for computing a check sequence on the basis of data included in the frame, a checking unit for checking whether the frame is corrupted by checking whether the check sequence coincides with a check sequence added to the frame in advance, a storing unit for storing a table that is a list of check sequences computed in advance on the basis of a plurality of pieces of data representing addresses of frames to be received by the information processing device, and a determining unit for determining whether the frame should be received by determining whether a check sequence computed by the computing unit on the basis of data representing a destination address of the frame coincides with any one of the check sequences included in the table.

A tube joint for a fuel tank includes a joint body having a tubular shape, and a barrier layer covering the inner surface of the joint body. The joint body is formed of a material which is weldable to a tank body, and the barrier layer is formed of a material which has fuel impermeability and a predetermined hardness. The barrier layer has an extension portion extending from a distal end of the joint body along an axial direction of the joint body. The extension portion includes a projecting portion which protrudes radially and outwardly of the extension portion at or adjacent to a proximal end of the extension portion such that a seal groove is formed between the projecting portion and the joint body, and a nail portion which protrudes radially and outwardly of the extension portion at or adjacent to a distal end of the extension portion.

An acceleration sensor comprises a fixed case member and a cover assembly collectively defining a closed space in which the oscillation plate and the piezoelectric element received therein. The oscillation plate and the piezoelectric element are oscillatably supported by a supporting portion formed on the central bottom portion of the fixed case member. The oscillation plate and the piezoelectric element are integrally oscillatable in two different modes consisting of: a 1/1 oscillation mode where the oscillation plate is irregularly deformed to have the peripheral portion oscillated with a single vector in the oscillation direction of the oscillation plate when the oscillation plate is oscillated with respect to the fixed case member at a resonance frequency f0; and a 1/2 oscillation mode where the oscillation plate is irregularly deformed to have two different half parts of the peripheral portion oscillated with their respective different vectors opposite to each other in the oscillation direction of the oscillation plate when the oscillation plate is oscillated with respect to the fixed case member at a noise frequency f01, and the resonance frequency f0 and the noise frequency f01 are out of the range of effective oscillation frequencies. Thus constructed acceleration sensor is of high performance and appropriate for automatic production at a low cost.

A developing device develops an electrostatic latent image formed on an electrophotographic photosensitive member. The developing device is mountable to a main assembly of an electrophotographic image forming apparatus. The developing device includes a developer carrying member for feeding a developer to the electrophotographic photosensitive member to develop the electrostatic latent image formed on the electrophotographic photosensitive member, a first electroconductive portion, a second electroconductive portion for cooperating with the first electroconductive portion to provide an electrostatic capacity, a first electrical contact for receiving a voltage to be applied to the first electroconductive portion from the main assembly of the electrophotographic image forming apparatus, and a second electrical contact for transmitting, to the main assembly of the electrophotographic image forming apparatus, an electric signal corresponding to an electrostatic capacity between the first electroconductive portion and the second electroconductive portion when a voltage is applied to the first electroconductive portion to detect a remaining amount of the developer by the main assembly of the electrophotographic image forming apparatus.

A cartridge includes a developing apparatus equipped with a developer containing portion containing a developer, a residual developer amount detecting device for detecting a residual developer amount in the developer containing portion, and a storage device capable of storing the latest residual developer amount information. An image forming apparatus includes a continuous rest time counter configured to count a continuous rest time of the image forming apparatus, and a controller which is configured to prohibit updating of the residual developer amount information to the storage device for a predetermined period after the end of the continuous rest time of the image forming apparatus when the continuous rest time counter indicates a time not shorter than a predetermined time. This structure provides an image forming apparatus and an image forming system in which no deterioration in detection accuracy occurs even if an unstable toner state occurs due to a long printing rest time.

An ink ribbon cassette is constructed such that it is unnecessary to wind off an ink ribbon at the start of every line printing process. The cassette includes two pairs of reels, each pair including an ink ribbon-winding off reel and an ink ribbon-winding up reel. The pairs of rails are rotatably mounted one above the other on a cassette casing which is detachably mounted on a carriage of a printer. The casing is provided with a driving shaft which is rotated in normal and reverse directions in response to reciprocal movement of the carriage. The driving shaft being provided with two one-way clutches transmitting the rotation of the shaft in opposite directions. Conveying members separately convey the ink ribbons for the respective pairs of reels and are driven by respective to the one-way clutches.
