摘要:
Gas generated from an inflator flows into a first portion of a main bag and each part of an inner bag, and the first portion is inflated toward an area in front of passenger's seat. Then, the gas filling the first portion which has been inflated flows into a second portion of the main bag. In this situation, the inflation direction of the second portion is more downward than the inflation direction of the first portion. As a result, a speed of backward inflation is decreased.

An airbag device which includes a passenger seat airbag module and driver's seat airbag module, detects a vehicle collision by means of an electronic control unit (ECU) thereof and inflates the airbags upon the vehicle collision. In the airbag device, the ECU and passenger seat airbag module are formed as a single unit which is installed in the passenger seat dashboard.

A transfer belt device having a roller unit. The roller unit includes a drive roller, a transfer roller, and a continuous transfer belt that is suspended around the roller unit. The drive roller rotates at a peripheral speed and drives the transfer belt such that a toner image may be transferred to it from an image carrier. The image carrier moves at a speed by means of the transfer roller. The drive roller is composed of a hard core roller that is coated with an outer layer of elastic rubber having a thickness t.ltoreq.1 mm, and is located downstream from the transfer roller in terms of the direction of movement of the transfer belt.

A device for recognizing and matching fabric pattern-forms for cutting is constituted by a marking CAD, a pattern-match control computer, a pattern recognition device body, a camera, a monitor and console, a mouse, a camera positioning robot, a cutter, a camera and video signal changeover mechanism, an iris controller, a pattern-match and cutting table, and so on. In the marking CAD, information concerning cutting point sequence data and pattern-matching points is generated and transferred to the control computer. The pattern-matching control computer moves the camera above each of the pattern-matching points to fetch an image to thereby measure the pattern position. The cutting point sequence data are revised on the basis of the result of the measurement. When poor recognition or erroneous-recognition occurs in the pattern recognition based on the image, the pattern position is determined manually through the monitor and console and the mouse.

2-(2-pyridylmethylsulfinyl)benzimidazole compounds are produced by subjecting 2-(2-pyridylmethylthio)benzimidazole compounds to oxidation with hydrogen peroxide in the presence of vanadium compounds in good yield and with low production of by-products.
摘要:
In correspondence with the graphic data having a spatial extent, there is the address data table configured of arrays, the dimension of which are not smaller in number than the dimensions of the extent of the graphic data. Coordinate transformation is performed between the graphic data and the address data table, whereby any desired point on each figure can be brought into correspondence with one array number of the address data table. Those memory addresses of a graphic data table at which the individual graphic data items are sorted, are subsequently stored in the address data table. In case of searching for graphic data located at any desired position, the corresponding array number of the address data table is obtained on the basis of the position, whereupon the desired figure can be searched for through that memory address to the graphic data which is stored. In a case where the memory space of the address data table corresponding to any desired one of cells (each of which is a subspace of a graphic space) is full, relevant information of indirectly utilizing a memory space assigned to another of the cells is substitutionally stored in the address data table, conjointly with the memory address of the graphic data table storing the corresponding graphic data so that the address data table can be used efficiently. When the figure discriminators of the graphic data are stored in the address data, lines or points, the relevant attribute information items, or the like can be extracted selectively and efficiently by deciding the figure discriminators on the searching operation.
