IPC: B21B37/50
Filed: 1985-04-30
Abstract: PURPOSE:To make faster the timing at which looper height control is started and to smooth looper rise control in the stage of the looper rise control during passing of a rolling material by setting the target angle value smaller than the target looper angle value. CONSTITUTION:The target angle value theta'ref10 deg. smaller than the target looper angle value thetaref shown by a solid line C is set in the rising stage of the looper to the target looper angle value thetaref16 deg. necessary for rolling. The timing for starting the height control of the looper 16 can be therefore made faster by the DELTAT time from the point A to the point B. A smooth displacement curve is obtd. as compared with the actual looper height displacement curve shown by a broken line C. The looper rise control is thus made smooth and the stable rolling is executed.

Title: Semiconductor integrated circuit device
Inventor: SHIMIZU SHINJI
IPC: H01L27/108
Filed: 1985-05-02
Abstract: PURPOSE:To suppress the intrusion of minority carriers into data storing capacitor elements, by providing a semiconductor region, whose conducting type is the same as that of a semiconductor substrate and whose impurity concentration is higher than that of the substrate, in the main surface part of the semiconductor substrate at the lower part of the data storing capacitor elements. CONSTITUTION:A P<+> type semiconductor region 6 is provided in the main surface part of a semiconductor substrate 1 at the lower part of a semiconductor region 5 of the forming region of a data storing capacitor element. The semiconductor region 6 is constituted in an area, which is the same as or larger than that of the semiconductor region 5. The semiconductor region 6 is formed so as to suppress the extension of a depletion region, which is formed on the side of the semiconductor region 5 from a P-N junction of an N<+> type semiconductor region constituting one electrode of the data storing capacitor element and the semiconductor element region 5. Since the region 6 is formed in high impurity concentration in comparison with the semiconductor substrate 1, the region 6 constitutes a potential barrier against minority carriers. Therefore, the semiconductor region 6 can suppress the decrease in capturing probability of the minority carriers, which are yielded in the semiconductor substrate 1 due to alpha rays, and also can suppress the intrusion of the minority carriers into the data storing capacitor element. Thus, software errors can be prevented.

Abstract: PROBLEM TO BE SOLVED: To reduce the formation of an undesired polymer substantially or to inhibit its formation perfectly and to thereby to produce a polymer product having a small polydispersity index by introducing an electron donor into a position higher than the level of the liquid in the reactor to minimize the reaction of isobutene with free boron trifluoride gas in the condenser. SOLUTION: An electron donor (e.g. an alcohol) in the form of droplets or a vapor is introduced into the reactor in an arbitrary position higher than the level of the reaction liquid in the reactor. In order to inhibit the formation of an undesired polymer, the electron donor in an amount of at least 3 mol per mol of free boron trifluoride vapor preestimated to form in the condenser or the connecting pipes is added to a position higher than the level of the liquid in the reactor. The reaction is practiced at -40 to +40 deg.C in a boiling liquid. The pressure in the reactor is desirabJy 0.2-4.0 bar. This process is suitable for the production of a polyisobutene having a number-average molecular weight of 350-5,000. The molecular weight distribution in this case is in the range of 1.2-2.5.

Abstract: PROBLEM TO BE SOLVED: To prevent pin holes from occurring on a packaging film which is packaging an article in a raised manner by making a form positioned inside a line connecting a periphery of a top plate of a lid with a peripheral top of a bank of a tray in the shortest distance. SOLUTION: A peripheral tip 11 of a lid 1 is positioned on a bank 21 of a tray 2, and the lowermost end 12 close to the peripheral tip 11 of the lid 1 remains on a stage 24 on a side wall internal face 23 of the tray 2. The peripheral tip 11 of the lid 1 positioned on the bank 21 of the tray 2 is positioned inside a line connecting a periphery 14 of a top plate 13 of the lid 1 with a peripheral tip 22 of the bank 21 of the tray 2. Thus when packaging such as shrink-packaging is performed, the peripheral tip 11 of the lid may not come into contact with a packaging film. Therefore since the packaging film may be rub against a hard part at the peripheral tip 11 of the lid, pin holes are difficult to occur on the film.
