Title: Filler for correcting surface
Inventor: OROFU SUNDEN
IPC: C09C3/10
Filed: 1980-05-28
Abstract: A surface modified pigment formed from kaolin material and a process of producing same are described. The pigment consists of pigment particles of kaolin material, and on the surface of the particles a primary and a secondary layer are precipitated. The primary layer consists of an anionic Al2O3-SiO2 hydrate gel having a molar ratio of SiO2:Al2O3 of from 3 to 30 and is present in a quantity corresponding to from 2 to 15% by weight of SiO2, based upon the original quantity of kaolin material. The secondary layer consists of a polymeric binder which is bonded to the primary layer by hydrogen or ion bonding and which is included in a quantity of at least 2% by weight, based upon the original quantity of kaolin material. The pigment is prepared by dispersing the pigment particles in water and providing them, while they are dispersed, with precipitated primary and secondary layers. The primary layer of anionic Al2O3-SiO2 hydrate gel is precipitated by acidifying water glass with an aluminium salt and acid, and the secondary layer is formed by adding a polymeric binder, the primary and secondary layers being bonded to one another by hydrogen or ion bonding. The pigment is retained in aqueous dispersion until after application. The surface-modified pigment is intended for use in paper and coats of paint.

IPC: C08F4/64
Filed: 1981-05-11
Abstract: PURPOSE: To obtain the titled polymer, consisting of a polymer of low intrinsic viscocity and a polymer having an intrinsic viscosity twice or more that of said polymer, having improved moldability without forming fly ashes, and useful for food containers, etc., by polymerizing propylene or its mixture with an α-olefin in the presence of a specific polymerization catalyst in two stages.  
     CONSTITUTION: Propylene or its mixture with an α-olefin is polymerized in the presence of a catalytic system containing a solid catalytic component containing titanium and an organoaluminum compound essentially. In the process, 40W 70wt% (co)polymer having an intrinsic viscosity (η) of 0.6W2.5dl/g is prepared  in the first stage, and 30W60wt% (co)polymer having an intrinsic viscosity (η) of 2.5W10dl/g and twice or more that of the former polymer is prepared in the  second stage by the two stage polymerization method. Thus, the aimed (co) polymer having an intrinsic viscocity (η) of 2W4dl/g based on the total polymer  is obtained.

Title: Ion-source device
Inventor: SUGAWARA TOORU
IPC: H01J27/08
Filed: 1981-05-11
Abstract: PURPOSE:To enable the ability of a cusp-field formation magnet to be maximally exerted, and increase the spatial homogeneity of plasmas by providing a magnetic member so that it unifyingly encircles a discharge chamber and a number of magnets located around the discharge chamber, and magnetically connecting magnetic poles located on the opposite side to the discharge spaces of the said magnets to the magnetic member. CONSTITUTION:Lines of magnetic force discharged from permanent magnets 3 form a cusp field inside a discharge coamber 2 as is indicated by a broken line 12 in the figure, and pass within a magnetic cylinder 11 outside the discharge chamber 2. Since the magnetic reluctance of the above outer magnetic route can be made sufficiently small compared to that of a conventional device, a cusp field can be formed inside the chamber 2 by making the gretest abilities of the magnets 3 to be displayed. In addition, since a mighty cusp field can be formed due to the reason mentioned above, the spatial homogeneity of plasmas can be increased.

Title: Nuclear reactor shutdown device
Inventor: SEKIGUCHI MINEO
IPC: G21C9/02
Filed: 1990-03-20
Abstract: PURPOSE:To increase the holding power of an electromagnet by providing cylindrical bellows which can expand and contract upward in the outer peripheral position of the upper part of a control rod, forming a stopper which comes into tight contact with the top end of the bellows near the upper aperture of a lower guide tube and forming a small-diameter flow passage hole penetrating axially through the control rod. CONSTITUTION:While the control rod 11 is magnetized and gripped by the electromagnet 3, the top end of the bellows 22 comes into contact with a stopper 23 and the flow of the coolant flowing into the lower guide tube 15 is shut off from flowing the outer side of the control rod 11 and is limited to only the flow through the small-diameter flow passage hole 27 in the control rod 11. The upward fluid force (buoyancy) acting on the control rod 11 is, therefore, increased and the upward force loaded on the electromagnet 3 is correspondingly decreased. The larger margin of the holding power of the electromagnet 3 is taken in this way.

Title: Current transformer
Inventor: KUBOSHIMA RIYUUICHIROU
IPC: H01F38/28
Filed: 1979-06-05
Abstract: PURPOSE:To rationalize the constitution of a current transformer by arranging a sheathed shielding core covered on the secondary coil between the primary coil and the secondary coil wherein the space of the core is reduced comparing with the case when a shielding core is separately provided. CONSTITUTION:After the secondary coil 3 is wound around a core 2 and insulation is applied, a shielding core 5 is arranged on the coil 3. Main insulation 6 is applied to the surroundings of the core 5. Furthermore, the primary coil 1 is concentrated and wound to constitute a current transformer. In this case, the location of the core 5 is not necessarily the inside of the main insulation 6 but the outside of the main insulation 6 will be allowed if the location is a place between the primary coil 1 and the secondary coil 3. The reduction of the primary coil 1 is contrived by covering the secondary coil 3 in a sheathed state and by raising the space factor of the core 5 without separately arranging the cores 5. And any type of current transformer is effectively manufactured.

Title: Master disk manufacturing device
Inventor: TAKEMORI HIROTOSHI
IPC: G11B7/00
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To obtain good tracking and a high quality address information signal in forming a groove and a pit in desired shapes without being mutually influenced by controlling a voltage level at the time of making grooves to correspond to the presence/absence of a pit in the process of manufacturing a master disk for a magneto-optical disk. SOLUTION: A pit signal Sp is inputted to a drive driver 11a and is also converted by an inversion circuit into an inversion signal S1 at a high level Vp or a low level 0. On the other hand, a groove signal Sg at a voltage level V2 is converted into a signal S3 at a level V2' by a conversion circuit 3, and a signal S2 and the signal S3 are added up by a synthesizing circuit 4, so as to obtain V1=V2' and V2=Vp'+V2'. In this case, V1<V2, and V1/V2 is <=90%, and input voltage levels to the drive driver at the time of making the groove to correspond to the presence/absence of the formation of a pit are V1 and V2 respectively. Consequently, the depth of the groove is uniformized irrespective of the existence of an adjacent pits, so that a tracking servo is stabilized, while influence of the groove is eliminated to prevent address information of pits is prevented from deteriorating.
