Abstract: An inflatable bag assembly is suitable for a seat of a vehicle such as an assistant driver's seat and has a bag which is inflatable in a curved configuration offset to one side. The bag is accommodated in a retainer case in a folded position. A gas generator has a gas outlet which is offset to one side with respect to the bag. Alternatively, the bag itself may be distributed less to one side of the retainer case than to the other side. Such a configuration of the gas generator or the bag allows the bag to begin inflating at the particular side mentioned above.

Abstract: An apparatus for preparing output data representative of an output image consisting of output image segments each defined by output picture elements such that each output image segments corresponds to each input picture element. The apparatus includes a pattern data memory for storing at least one set of basic output-image unit pattern data each representative of a basic pattern of position of output picture elements defining a basic output image area, and a device for preparing the output data for each output image segment whose pattern of positions of output picture elements is identical with the basic pattern represented by any set of basic output-image unit pattern data stored in the memory. The output data are prepared based on the appropriate set of unit pattern data, without determining the positions of the output picture elements lying within the outline of that output image segment obtained from the corresponding input picture element.

Abstract: A sheet feeder for a printer selectively feeds a continuous sheet and a cut sheet to a printing mechanism including a platen and a print head. The continuous sheet is fed by a pair of pin tractors and the platen while the cut sheet is fed only by the platen. At least one sheet presser roller is provided for guiding the feeding of the cut sheet, which moves toward the platen when the cut sheet is fed so as to hold the latter against the platen, and moves away from the platen when the continuous sheet is fed. A switching lever sets the sheet feed mode, which when moved to a first position causes to feed the cut sheet by rotating the platen and when moved to a second position causes to feed the continuous sheet by rotating both the pin tractors and the platen.

Abstract: A sewing machine comprising a threading device and a needle-bar raising means. A threading switch is operated and a sewing machine motor is stopped. Subsequently, thread is passed onto a linkage, a needle bar is disconnected from an arm shaft, and the needle bar is raised to a given position. After the needle bar is set in its uppermost position, thread stretched out from the linkage 38 to the front of an eye in a needle is passed through the eye in the needle. If the end of thread is manually held in front of the eye in the needle to stretch out prior to threading operation, the needle bar does not lower, thus enhancing operational safety and preventing thread from loosening.
