Title: Joining device for metallic sheet
Inventor: INABA HIRAKAZU
IPC: B21D39/03
Filed: 1985-12-24
Abstract: PURPOSE:To firmly join a metallic sheet by a device having a simple structure, by forming a die body in a hollow cylindrical shape consisting of an elastic material, when bringing plural pieces of superposed metallic sheets to an upsetting deformation by a punch and a die. CONSTITUTION:Two pieces of metallic sheets 1a, 1b are pressed by a punch 3, in a superposed state, and pressed against the upper end face of a die body 4. In this case, the die body 4 is formed in a hollow cylindrical shape made of hard rubber which can be deformed elastically. When a push-in stroke of the punch 3 further increases, a pressure receiving part of the metallic sheets 1a, 1b is bulged in the pressure direction of the punch 3, a bottomed cylindrical projecting part 8 is formed, and it is pushed into a die hole 2. When the projecting part 8 reaches a static pressure receiving surface of the upper end of a shaft-shaped pressure receiving member 6, it stands still, and it is bulged in the radial direction of the die hole 2 by an additional descent of the punch 3. In this way, the projecting part 8 is upset integrally as one body structure, and the metallic sheets 1a, 1b are firmly joined.

Abstract: PURPOSE:To compensate the temperature change of dark currents in a light-receiving region precisely by making the junction depth and impurity concentration of a well region forming a photosensitive picture element section in an OB (optical black) region shallower or lower than a well region shaping a photosensitive picture element section in the light-receiving region. CONSTITUTION:Junction depth in the lower section of an N-type region 10 as a photosensitive picture element section is made extremely shallower than a conventional P well in the shape of a P well 17 in all OB region, and the photosensitive picture element structure of a light-receiving region and the OB region is formed to quite the same shape with the exception of a P-well shape in the lower section of the N-type region 10. That is, both the light-receiving region and the OB region are treated under the same conditions including effects by the formation of an aluminum film, etching and hydrogen, thus generating no difference in the interface level density of Si and SiO2. The OB region is not affected by optical incidence complete1y, and generates quite the same dark currents as the dark state of the light-receiving region. Accordingly, the fluctuation of the dark currents of the light-receiving region due to a temperature change can be compensated accurately by the dark currents of the OB region.

Abstract: PROBLEM TO BE SOLVED: To attain cost down without increasing man-hour for production by connecting a voice coil and a diaphragm while providing a slit between the voice coil and the diaphragm almost in long diameter direction. SOLUTION: A diaphragm 19 comprises a cone 17 and an edge 8. Then, the cone 17 and a voice coil 10 are connected by applying an adhesive agent 19A in the short diameter direction of the slender track-shaped diaphragm 19. At the same time, they are disconnected by applying no adhesive agent in long diameter direction and further, by providing a slit (a), buffering between the voice coil 10 and the cone 17 is prevented. Thus, since arcuate parts near both the sides of the voice coil 10 at a sharp apex angle (b) in the short diameter direction of cone 17 of the diaphragm 19 are connected but the cone 17 and the voice coil 10 are disconnected in the long diameter direction, the high frequency side is emphasized and level-up of high range frequency or expansion of high critical frequency can be attained.

Abstract: PURPOSE:To attain the desired high resolving power and a high feeding speed with a numerical controller by multiplying the counted position command pulse number in response to the position command resolving power and producing a speed command signal of an axis driver based on the deviation between the counted pulse number and a position detection pulse. CONSTITUTION:The count value C1 of the position command pulses synchronous with the clock pulse received from a pulse distribution part 6 via a position command counter 70A of a servo control part 70 is multiplied with a coefficient P corresponding to the resolving power of one of storage parts 23A - 23C obtained via a program analyzing part 4 in response to the command resolving power given from a position command resolving power instruction part 21 via a resolving power conversion circuit 70E. Thus the pulse count value is multiplied in accordance with the command resolving power as (C1XP). Then the control command value C5 is obtained with addition of the basic position command value C4 of a motor 8 of a counter storage circuit 70F and stored in a control command storage part 70G. The deviation C6 is counted by an arithmetic circuit 70H between the value C5 and the count value C2 obtained via a position detector 10 and a position detection counter 70B. At the same time, a servo circuit 9 outputs a speed command signal in accordance with the deviation C6. Thus it is possible to attain the desired high resolving power and a high feeding speed with a numerical controller.

Filed: 1995-10-13
Abstract: PROBLEM TO BE SOLVED: To provide a structure wherein the cutting of a flexible sheet such as toilet paper can surely be performed by one hand, and in addition, the leading end of the paper is easy to be pulled out from the roll at the time of a next usage. SOLUTION: In a flexible sheet roll holder 1, when a flexible sheet 6 is pulled out from a sheet roll 2, a rotating member 4 rotates while interlocking with the pulling out motion. Then, under a state wherein the rotating member 4 has rotated at a specified angle which is 180 deg. or higher, a stopper moving member 12 which rotates while interlocking with the rotating member 4, moves a stopper member 8 to a position where the stopper member 8 is engaged with a stopper engaging part 4a on the rotating member 4 side. The stopper member 8 is engaged with the stopper engaging part 4a, and by doing so, prevents the rotating member 4 from rotating.  When the flexible sheet 6 is cut by a cutter part 16 under this state, the engagement between the stopper member 8 and the stopper engaging part 4a is released, and the rotating member 4 rotates, thus the flexible sheet 6 is let off from the wound roll.
