Abstract: PROBLEM TO BE SOLVED: To suppress the thickening in the tip part of a material and to obtain products excellent in surface quality by imparting tensile force in the neighborhood of the middle part of width in the tip part to the material at the time of width-pressing the tip part of the material with press dies. SOLUTION: An edging press device provided with press dies 1 which have a tapered part and a parallel part following the tapered part and is movable in the width direction of a material, press rolls 4 which are movable in the plate thickness direction of the material and a means for imparting tensile force in the neighberhood of the middle part in the tip part of the material is used. The carrying-in of the tip of the material 10 is confirmed with a sensor 7 on the inlet side and width pressing is started. Until the carrying out of the tip of the material 10 is confirmed with a sensor 8 on the outlet side, a tensile force setting device sets the tensile force with a tensile force setting device based on a press load detected with a press load detector 3.  After the carrying out of the tip of the material is confirmed with the sensor 8 on the outlet side, the tensile force is released with the tensile force setting device. The tensile force is adjusted or released with a control part of a press roll driving device according to an output signal from the tensile force setting device.

Abstract: PURPOSE:To improve the performance of a vector instruction with vector postprocessing arithmetic operation. CONSTITUTION:An inner product and total sum instruction for a case wherein vector length(VL) is longer than the maximum storage word length(VRL) of a vector register is executed. Data read out of the vector register 2 stored with the data by the VRL are distributed to four vector computing elements 3a-3d and processed at the same time. The four found data are sent to a postprocessing computing element VAP 6 and an adder 8 calculates the total sum of the data and data in a scalar register SR 11 or work register WR 14. This value is the current arithmetic result of the VL. The result is written in the WR 14 and SR 11 and those processes are regarded as one loop. In a 2nd loop, the data written in the WR 14 in the VAP 6 are used instead of the data of the SR 11 to perform the arithmetic of the VAP 6.

Title: Solid-state image pick-up device
Inventor: YAMAMOTO HIROMASA
IPC: H04N5/341
Filed: 1990-10-30
Abstract: PURPOSE:To manufacture the title solid-state image pick-up device capable of reducing smear by a method wherein said device is provided with a charge transfer part to transfer the signal charge photoelectronically converted by a photo-detector to an output circuit, a conductive film formed on the charge transfer part through the intermediary of an insulating film as well as a metallic photo-shielding film selectively deposited on the conductive film. CONSTITUTION:A polycrystal silicon film 9 is formed on transfer electrodes 6-1, 6-2 comprising the polycrystal silicon as if covering said electrodes 6-1, 6-2 through the intermediary of a thin insulating film, besides, an interlayer insulating film 4a covering the surface of a substrate is partly removed above transfer region so as to expose the polycrystal silicon film 9. Next, a photo-shielding film 5a in specific thickness is deposited on the removed part using e.g. the tungsten selective deposition. In such a constitution, since the sidewall of the interlayer insulating film 4a on the upper part of a photodetector part 3 (n type impurity region) is covered with the photo- shielding part 5a, the oblique incident beams obstructed by the sidewall parts does not reach the charge transfer region. Through these procedures, the smear of the title solid-state image pick-up device can notably be reduced thereby enabling a vivid image to be produced.
