Title: Method and device for processing information
Inventor: TASHIRO HIROHIKO
IPC: G06F12/00
Filed: 1996-02-15
Abstract: PROBLEM TO BE SOLVED: To input/output information corresponding to management information while keeping secrecy. SOLUTION: It is discriminated whether a scret document mode is set or not (step S401) and when that mode is not set, image data read from an original is stored in a hard disk together with a file allocation table (FAT) (step S405) and when these stored image data are outputted (step S406), copy processing is immediately finished. When the secret document mode is set, on the other hand, after the image data are stored and outputted (steps S402 and S403), the FAT and image data stored in the hard disk are erased (step S404) and then, copy processing is finished.

Title: Manufacture of brazed bellows
Inventor: WATABE KAORU
IPC: B23K1/00
Filed: 1987-03-05
Abstract: PURPOSE:To reduce the cost of a bellows and to improve the durability by screen-printing a solder paste on the peripheral edge part of a sheet stock and a joining preventative on the other parts respectively, then, heating the sheet stock inside a furnace by its assembling. CONSTITUTION:The brazing filler metal 5 as a past is subjected to screen printing over the whole periphery of the inner peripheral edge part of one part face of the sheet stock 3 for a circular annular bellows and solidified by drying. A joining preventative 6 is subjected to screen printing on the parts excluding the inner peripheral edge part of the same face and solidified by drying. The brazing filler metal 5 and joining preventative 6 are then printed on the outer peripheral edge part of the sheet material 7 for bellows of the other part adjoining with the sheet stock 3 and the other parts and the sheets 3, 7 are alternately laminated and heated inside a furnace to form the bellows part of the bellows 1. Since the brazing filler metal 5 and joining preventative 6 can be subjected to mass production by printing the manufacturing cost is reduced and the stress concentration of a brazing part can be prevented, hence the durability of the bellows is improved.

Filed: 1978-04-28
Abstract: PURPOSE:To attain highly-efficient current amplification, without losing bothway operation stability, maintaining the operation margin of an I<2>L, by integrating the I<2>L and an ordinary bipolar element on one substrate at the same time. CONSTITUTION:A current is supplied via resistance 5 to the emitter of lateral transistor Q4 of the bipolar circuit, its emitter is grounded via base resistance 6, and one of collectors is connected to the base. With resistance 5 made higher than resistance 6, the emitter current can be controlled and, in consequence, resistance 6 increases the base potential of Q4 when Q4 serves as the base current supply of longitudinal transistor Q3, thereby preventing the saturation of Q4. At this time, the values of resistances 5 and 6 are selected so as to make emitter-base forward voltage VF of Q4 less than the base potential and the emitter current is made approximate twice that of injector 2 of the I<2>L. In the above constitution, the current amplification factor can be secured sufficiently, unstable operation such as the saturation of Q4 never occurs, and the I<2>L operation margin is maintained.

Further, the operational amplifier 23 is connected to constitute the current-voltage converting circuit; and a charging current i1 flows from a member 5 to be charged to the inverted input terminal 21 as a current is and a voltage corresponding to the current is is developed at the output 24. The univerted input terminal 22, on the other hand, is grounded to hold the input terminal 22 at the earth potential. The differential inputs 21 and 22 are in an imaginary short- circuit state, so the inverted input terminal 21 is also at the earth potential. Therefore, the bias voltage at a point B of a control voltage source 7' never varies with the current is and the voltage applied to a grid 6 is controlled accurately.
