Abstract: 1291552 Olefin polymerization catalyst MONTECATINI EDISON SpA 8 Jan 1970 [10 Jan 1969] 916/70 Heading C3P Olefins are polymerized utilizing as a catalyst a reaction product of a hydrated magnesium halide of the formula MgX 2 .nH 2 O, wherein X is halogen and n>0, with a halogen containing titanium or vanadium compound under such conditions that the hydrated magnesium halide is transformed at least on the surface into an anhydrous magnesium halide, which product is activated with a hydride or organometallic compound of Groups I-III. The reaction product of the magnesium halide and Ti or V compound may be prepared by reacting the hydrated magnesium halide with a stoichiometric excess of the Ti or V compound, either in a normally liquid state, or, if it is normally a solid, in solution in a solvent which is inert to the magnesium halides, preheated to the boiling temperature of the compound or solution, followed by removal of the liquid phase from the reaction zone. In the examples, (1) ethylene is polymerized in n-heptane in the presence of hydrogen utilizing as catalyst a mixture of Al(iso- C 4 Ha) 3  and the reaction product of TiCl 4  and MgCl 2 .6H 2 O, MgCl 2 .2H 2 O, MgCl 2 .1H 2 O or MgBr 2 .6H 2 O; and (2) propylene is polymerized in n-heptane in the presence of hydrogen, utilizing as catalyst a mixture of Al(C 2 H 5 ) 2 Cl and the reaction product of TiCl 4  and MgCl 2 .- 6H 2 O.

Title: Method and apparatus for forming pretzels from paste fibres made in advance
Inventor: ZWICKER HORST
IPC: A21C3/08
Filed: 1990-02-07
Abstract: In a process for shaping pretzels from preprepared dough strands 4, the dough strands 4 are continuously transported at variable intervals between a receiving station 1, a knot-forming station 2 and a release station 3, the ends 6 of each dough strand 4 being moved against each other between the receiving station 1 and the knot-forming station 2, and the central part and side sections of the dough strand being lowered beneath the ends 6, so that they form an arch-shaped loop, which is rotated through 360 DEG  at the knot-forming station with the aid of two rotatable brush rolls 18, 19. After this the central part and the side sections are shifted upward to a horizontal position. After their release the ends 6 of the dough strand fall on to the side sections of the dough strand. The ends 6 of each dough strand are clamped between the arms of two upper sides, folded inwards in a U- shaped manner between the receiving station 1 and the release station 3, of gripping belts and conveyed in the transport direction. The upper sides 10 of the gripping belts 5 come together between the receiving station 1 and the knot-forming station 2 and separate again between the knot-forming station 2 and the release station 3. The process and the device for carrying it out permit a high throughput, supply of dough strands to the receiving station 1 at variable intervals being an advantage. …<IMAGE>…

Title: Method and device for driving antiferoelectric liquid crystal element
Inventor: KIMURA SATORU
IPC: G02F1/133
Filed: 1997-01-06
Abstract: PROBLEM TO BE SOLVED: To suppress a change in a threshold value characteristic due to the difference of a display pattern and to reduce cross talk by inverting polarity of a voltage applied to a scan electrode and the voltage applied to a signal electrode for very selection of the scan electrode and for every frame period. SOLUTION: One frame period in the drive voltage of the scan electrode consists of a selector period when the scan voltage Vr is applied as a written pulse, a non-selection period when a hold voltage Vb is applied and an erase periods when an applied voltage is made zero (reset voltage). A third polarity signal f is inverted in its polarity for every frame period and for every selection of the scan electrode. The polarity of the applied voltage to the scan electrode and the signal electrode are set according to the polarity of this third polarity signal f. For instance, in scan electrode waveforms a1 -a3 , respective scan voltages Vr are made the positive polarity. The scan electrode Vr is inverted to the negative polarity in the selection period of the scan electrode waveform a4 .

Title: Microcomputer
Inventor: UCHIMURA HIROSHI
IPC: G06F12/06
Filed: 1994-01-06
Abstract: PURPOSE:To lay out a memory space of an external device (extention memory) which is added to a chip while securing a least necessary memory space for a storage such as a built-in ROM, etc., when a memory map is laid out for a single-chip microcomputer. CONSTITUTION:In reference to a single-chip microcomputer, a memory space used for a built-in ROM is divided into a working memory space and a non- working memory space based on the variable address value set on an area register. Then the non-working memory space is laid out in a memory space set for an extension memory. Thus it is possible to set/change the memory space of the built-in ROM to a least necessary space in response to the acutaul working state just by making a user set/change the variable address value even if the memory space of the built-in ROM is decided according to the storage capacity of the ROM when the microcomputer 18 shipped plant. Therefore the non-working memory space can be best used.

Abstract: PURPOSE: To obtain a high-dielectric strength planar semiconductor device by enlarging the curvature radius at the edge of a planar-structure pN junction part by ion injection.  
     CONSTITUTION: One main face of N-type Si substrate 10 is oxidized to form mask layer 11 such as SiO 2 , and hole 12 is formed by photo etching to expose a part of substrate 10. Substrate 10 is held by holder 13, and holder 13 is set in an ion injecting unit under the state where holder 13 is inclined by prescribed angle θ in respect to the incident direction of ion beam 14. While rotating continuoulsy holder 13 at the center of the axis under the state where holder 13 is inclined by angle θ, ion beam 14 is injected to one main face of substrate 10 from the oblique direction. Since ion beam 14 is injected to one main face of the substrate from the oblique direction, edge Y of PN junction part 16 can be formed with a large curvature radius.

Title: Dihydropyran for wafer priming and wafer priming method using the same
Inventor: TEI SHINKO
IPC: C07D309/18
Filed: 1998-01-06
Abstract: PROBLEM TO BE SOLVED: To enable the priming of dihydropyran using the dihydropyran as a primer to obviate the production of harmful byproducts in the process of forming a hydrophobic org. film by reaction with a wafer by using the dihydropyran as the primer for processing the wafer surface. SOLUTION: The dihydropyran is used as the primer for processing the wafer surface before coating of a photoresist for production of semiconductor devices. Namely, the hexamethyl disilazane mainly used heretofore as the conventional primer generates harmful gaseous ammonia at the time of reaction with the wafer surface. In contrast, the dihydropyran as the primer reacting with the surface of the wafer does not generate gases as the byproducts at all. Then, the need for discharging the gases is eliminated. Namely, the dihydropyran is formed by the addition reaction of the double bonds of the dihydropyran on the wafer surface and, in such a case, there is the advantage that the reaction byroducts are not generated in the addition reaction.

IPC: H01J29/76
Filed: 1978-01-09
Abstract: PURPOSE: To avoid misconvergence, by providing fine slit to which the insert can be inserted, at the joint of sectioned cores.  
     CONSTITUTION: Each sectional core is provided with the vertical winding 13 and the deflecting yoke is assembled by mating the sectional planes. A part of the sectional core provides the slit 15 where the insertion material 16 such as paper is inserted. Thus, the horizontal magnetic field due to the horizontal winding at left side is totally weakened with the increase in the magnetic resistacne of the closed magnetic path and the entire horizontal magnetic field is shifted left. Accordingly, when only the horizontal magnetic field is condidered, it is equivalent to deflect the core to left, avioding misconvergence.
