Title: Formation method of pb-substituted perovskite material for thin-film dielectric material and structure containing said material
Inventor: SUKOTSUTO AARU SAMAAFUERUTO
IPC: H01B3/12
Filed: 1993-05-28
Abstract: PURPOSE: To maximize the dielectric constant of a thin-film perovskite material, without maintaining a substrate at a high temperature by adding lead to this material. CONSTITUTION: The dielectric constant of a perovskite material increases below the queue temperature according, as the crystal grain size is decreased. Lead reduces the critical crystal grain size of the perovskite material. Therefore, the lead is added to an original perovskite material having an original critical crystal grain size, and then the layer of a lead-strengthened perovskite material having a mean crystal grain size smaller than the original critical crystal grain size is formed. Thus, the dielectric constant of this layer can be made to be higher than the dielectric constant of the original perovskite material, having a mean crystal grain size similar to the mean crystal grain size of this layer, and preferably, the resistance of this lead-strengthened material can be increased and/or the dielectric tangent can be reduced by doping it with an acceptor dopant.  A structure on a substrate surface includes a conductive layer and the layer of this lead-strengthened perovskite material brought into contact with the conductive layer.

Filed: 1987-05-25
Abstract: PURPOSE:To avoid the need for external energy at all, by forming the self- starting permanent-magnet rotary-machine of a multi-magnetic phase magnetic- circuit composed of two sets of closed magnetic circuits. CONSTITUTION:A multi-magnetic phase magnetic-rotary machine is composed of permanent magnets 1 for a stationary field system, permanent magnets 2 for a rotor, field pole magnetically-permeable-discs 3, stationary field poles 6, magnetic shield rings 8, magnetic conduction elements 9, magnetic feed sections 10, a rotor frame 13 and a main shaft 15, a main unit frame 17, and the like. To apply magnetic polarity, the magnetic proportion of multi-magnetic phase patterns is performed by the magnetic shield rings 8 and the magnetic conduction elements 9 rotating in the same manner as that of the rotation of a rotor. According to the magnetic proportion, from the rotor, the rotational torque of magnetic repulsion and magnetic attraction is generated. Besides, by the magnetic poles 4-5 of the rotor, magnetism is branched to the magnetic conduction elements 9 and is combined with magnetism for a field system, and a stationary field system magnetic-force is intensified. As a result, the permanent magnets are set to be energy sources, and so the energy of a power source is not needed at all.

Title: Nut attaching and detaching apparatus
Inventor: OKADA KENJI
IPC: G21C13/02
Filed: 1984-06-23
Abstract: PURPOSE:To diminish radiation exposure for a workman of atomic reactor by providing, in a nut attaching and detaching apparatus of a reactor pressure vessel, an absorbing mechanism for nut motion inside the apparatus, a lifting and holding mechanism for a disconnected nut, and a soft-touch mechanism. CONSTITUTION:An arm 9 lowers an apparatus so low that the lower end of the apparatus will touch on the nut 4. A moter 13 rotates to make a rotating groove 4a to engage a pawl 4b, and as the moter rotation raises the nut 4, elements below a holding nut 20 also rise. Consequently, a lifting pawl 16 is closed by a spring 18 on a return stroke of an air cylinder 17, and rises holding the nut 4. When coupling of the nut 4 with a stud bolt is released, a nut holding spring 21 mounted at the lower end of a movable shaft 14b supports the weight of the nut 4 to prevent a screw thread from damaging. When the apparatus moved to the fixed position and the moter 13 rotates reversely, the nut 4 breaks away from the lifting pawl 16. In addition, a load lying on the screw thread can be reduced in mounting the nut 4 because the holding spring 31 supports the nut 4.

Abstract: PURPOSE:To stably manufacture a carbon film at high film-forming speed over a long period by synchronizing the output of high-frequency waves or microwaves producing plasma decomposing a carbon compound-type gas with a positive or negative A.C. bias to be impressed on a substrate. CONSTITUTION:A carbon compound-type gas is introduced via a gas-introducing hole 3 into a high-frequency plasma CVD apparatus and discharged through a gas exhaust port 4. Further, high-frequency electric power is impressed from a high-frequency electric power source 2 on a high-frequency coil 1 to produce plasma. The above gas is decomposed by means of this high-frequency plasma, by which a carbon film of diamond, etc., is formed on a substrate 5 of the prescribed temp. held by a substrate holder 6 containing a heater 8. In the method of manufacturing the above carbon film, an A.C. bias is impressed from an A.C. bias electric power source 7 on the substrate 5, and further, the above high-frequency output is outputted while being synchronized with a positive or negative A.C. bias. By this method, a diamond-like carbon film or an isometric carbon hard carbon film can be formed at high film-forming speed, and this speed can be maintained even if film formation is continued for a long time.

Abstract: PURPOSE:To ensure a large degree of compression so as to ensure a satisfactory sealability by covering the outer periphery of a core made of low density porous polytetrafluoroethylene which has been fibrillated, with a sheath member made of high density sintered polytetrafluoroethylene. CONSTITUTION:A jacket gasket 1 is used as a seal for flange part coated therewith a lining made of PTFE(polytertrafluoroethylene) or a rubber lining. In this case, in order to manufacture the gasket 1, low density (less than 1.8) porous PTFE is stretched into a sheet-like shape so as to be fibrillated. Then, the porous TOUGH sheet is stamped so as to form a ring-like core 2. Next, opposite end surfaces of the core made of porous PTFE are covered with a sheath member 3 made of high density sintered porous PTFE. Accordingly, since the porous PTFE has a degree of compression as more than two times as high as that of a joint seal or PFE monomer, a satisfactory sealability can be ensured.
