A method for inspecting whether a print pattern composed of a number of dots is acceptable, an apparatus for inspecting such a print pattern, and an automatic print sorting system are disclosed. A print pattern of an acceptable print sample and a print pattern printed on an article to be inspected are compared with respect to dot distribution, dot density, and other factors. The print patterns on all articles on a high-speed production line can be automatically inspected.

A selecting mechanism for a vehicular transmission operating apparatus having an interlock plate rotatably mounted to a mounting base plate. A selection shaft fixed at one end to the interlock plate is directly connected to the shift rod so as to transmit rotation of the shift rod directly to the interlock plate. A selection snugness arm is rotatably mounted to the mounting base plate and interacts with the selection shaft. A torsion spring retains the snugness arm in its non-rotated position. A snugging mechanism is connected to the snugness arm and has a spring loaded snugging member which rides on a variable heighth cam face so as to impart a variable resistance upon rotation of the shift rod.

A centrifugal separator comprises a centrifugation chamber, gas inlet ports for introducing a gas into the centrifugation chamber so as to whirl the gas, a clean gas discharge pipe provided on the upper portion of the centrifugation chamber, and a guide member secured to the lower portion of the centrifugation chamber. The guide member has an annular groove, outer fine holes made in the groove, a guide portion projecting conically inward the centrifugation chamber, and an inner hole made in the center of the guide portion. A gas including particles is introduced into the centrifugation chamber, in which the particles are separated. The separated particles are trapped in the groove with gas, then discharged from the outer holes. The clean gas removed of the particles is guided by the guide member to direct to the gas discharge pipe, at the same time the particles with gas toward the guide member also are guided by the guide member to be subjected to the centrifugal force.

Disclosed is a fire extinguisher (100) comprising a fire extinguisher cylinder (10) for a fire-extinguishing agent. The fire extinguisher cylinder (10) comprises a mouth portion as an opening, a shoulder, a cylindrical body portion, and a bottom portion and is shaped with use of a resin provided with no joint. In addition, the body portion in the fire extinguisher cylinder (10) has a thickness from 1 mm to 5 mm, and a crystallinity of the resin is from 13% to 30% at the sites other than the mouth portion and the bottom portion. Accordingly, the fire extinguisher (100) is lightweight and does not rust. Further, the fire extinguisher (100) has high strength or high pressure resistance.
摘要:
A transmitting circuit transmits data to which an error detection code is attached to a receiving circuit via a transmission path. When detecting the error of the data received via the transmission path, a receiving circuit transmits a retransmit request for the data in which the error is detected to the transmitting circuit. The receiving circuit enters a termination unit adjustment period using the error detection of the received data as a trigger and updates the resistance values of a receiving side termination unit installed at the termination of the transmission path to an appropriate value within the termination unit adjustment period.

A memory controller which is connected to a memory module having an ECC (Error Check and Correction) function and which controls access to the memory module, the memory controller, has an error detection unit configured to detect an error bit and a position of the error bit by reading, from the memory module, information on codes of the ECCs corresponding to a plurality of read data read from the memory module, a buffer configured to temporarily store the plurality of read data, and a determination unit configured to determine, when the plurality of read data stored in the buffer include a number of data in which a correctable error is detected by the error detection unit and error detection positions of the detected data are the same as each other, that a correctable error is included in a group of the plurality of read data.
摘要:
Binary information previously recorded in an innermost rim side area is enabled to be stably reproduced. A record medium is formed by sequentially laminating a first information layer 2, an intermediate layer 3, a second information layer 4, and a cover layer 5 onto a substrate 1. First grooves are previously formed in the innermost rim area of the substrate 1. Second grooves are previously formed in an area where data is recorded. The first grooves are set to be shallower and narrower than the second grooves. Thus, such a situation that a BCA signal is modulated by diffraction due to the grooves can be reduced.

A parallelism adjusting mechanism of a probe card is provided. The parallelism adjusting mechanism can bring probes held by a probe card into uniform contact with a wafer even if a parallelism between a mounting reference surface for the probe card and the wafer as a test object is lost. To achieve this purpose, specifically, to adjust a parallelism of a probe card (101) that holds a plurality of probes (1) for electrically connecting a wafer (31) as a test object and a circuitry for generating a signal for a test with respect to the wafer (31), adjusting screws (22) as at least part of an inclination changing unit are provided. The inclination changing unit changes a degree of inclination of the probe card (101) with respect to a mounting reference surface (S1) of a prober (202) for mounting the probe card (101) thereon.
