Title: Shaftlike rough shape material for form rolling of under head recess of thread portion
Inventor: IKUSHIMA KOICHI
IPC: F16B35/00
Filed: 1995-03-31
Abstract: PURPOSE: To eliminate a swell due to excess thickness remained on the side face of a flange by forming on an end face of the flange a recessed part for storing the excess thickness produced in the roll forming of an under head recess of a thread portion. CONSTITUTION: Thread rolling, as well as under head clearance rolling, is performed on the other end of the shaft part 2 of a rough shape material by the use of a form rolling device, forming a thread part and also recessing to provide an under head recess 2b. In this case, the excess thicknesses 4, 5 are still produced, of which the excess thickness 4 moving in the radius direction of an end face of the head 1 successively fills the recessed part to form a bearing surface 4a with a new end face. As a result, the excess thickness 4 is not caused to swell on the side face 1b of the head 1. The excess thickness 5 swelling on the other end of the under head recess 2b of the shaft part 2 is neither caused to interfere with the rod by being crushed easily through burnishing because the shaft part 2 is a simple cylindrical face.  Therefore, such a product can be fixed by a large axial tension by expanding the flat face of the bearing surface 4a.

Abstract: PURPOSE:To easily and visually recognize the present position of a working ship with a control station by loading a loran C, a transmission data processor and a ship transmission telephone set to the working ship. CONSTITUTION:A working ship obtains a coordinates signal to show a present position with a loran C6 and inputs this through an RS-232C input part 7 to a transmission data processing part 8. The transmission data processing part 8 overlaps the coordinates signal and the classification data of its own ship to other ships and forms the transmission data together with the code number of its own ship. The transmission data are transmitted through a modulator 9, a ship transmitting telephone set 11 and a transmitting antenna 10 to a control station. At the control station, the received data are processed by a data processor and visually displayed at a display device.

Title: Liquid crystal electro-optic element
Inventor: CHINO EIJI
IPC: C08F220/28
Filed: 1991-04-09
Abstract: PURPOSE:To provide a liquid crystal display body having high display quality and reliability by making the resistivity of a light scattering film almost equal to a liquid crystal single body. CONSTITUTION:When a polysilane is used as a polymn. initiator of a light scattering film 1, the polysilane opens and changes into radicals by irradiation of UV ray. These radicals crosslink the polysilane in a three-dimensional state as well as act as a polymn. initiator to polymerize a UV curing resin. The polysilane which is soluble in a solvent becomes insoluble by irradiation of UV ray, and at the same time, low mol.wt. polysilanes and UV curing resin are polymerized and fixed to the polymer matrix. Thereby, elution of unreacted low mol.wt. matter and polymn. initiator as impurities into the liquid crystal is prevented, and as a result, the resistivity is increased.

Abstract: PURPOSE:To suppress increase in the number of vanes associate with lower drive voltage by furnishing a No.2 group of vanes to be at a neutral potential in terms of high frequency between a No.1 group of vanes. CONSTITUTION:An arbitrary one of No.2 group of vanes 24 is arranged in the middle and the resonance cavities of a positive electrode part is divided by two No.1 vanes adjoining to this one of the No.2 vanes 24. Accordingly a high-frequency electric field is generated between the vanes 21, but in a space with No.2 vane 24 in the middle, the high-frequency electric field emitted from the No.1 vanes intrudes into adjoining No.1 vanes 21 via No.2 vane 24. That is, if one resonance cavity is assumed, there are three high-frequency electric fields, one generated between No.1 vanes 21, another generated between No.1 vane 21 and No.2 vane 24, and a third generated between No.2 vane 24 and No.1 vane 21, wherein these high-frequency electric fields are oriented in the same direction. This reduces the number of vanes if the drive voltage is the same, and No.2 vane 24 can be with greater plate thickness.

Title: Electron gun
Inventor: NAKANISHI TOSHIO
IPC: H01J29/56
Filed: 1986-04-03
Abstract: PURPOSE:To enable any deflection aberration caused by deflection magnetic field to be corrected electrostatically by connecting a pair of electrode pieces on one side to a focusing electrode, and at the same time applying a compensatory focusing voltage synchronous with the deflection magnetic field to a pair of elecrtode pieces on the other side. CONSTITUTION:A voltage (V+v), which is higher than the focusing voltage V applied to vertical electrode pieces 6a, 6c, is impressed on horizontal electrode pieces 6b, 6d. Then electric forces 12 act on a traveling electron beam 7 on account of an electric field generated inside a quadripole and its cross-sectional form becomes a longitudinal ellipse. If the compensatory focusing voltage v is negative, the directions of the electric forces 12 are reversed so that the cross-sectional form of the electron beam 7 becomes lateral ellipse. Since electrode pieces 6a, 6c are maintained at the focusing voltage V in either case, the electron beam 7 can be deformed in either longitudinally or laterally long shape on account of attractive or repulsive action depending upon positive or negative sign of the focusing voltage v impressed on the electrode pieces 6b, 6d. Therefore, when the focusing voltage v is applied to electrode pieces, 6b, 6d, the cross-sectional form of the electron beam can be changed in preset shape so that the deflective aberration can be corrected.

Abstract: PURPOSE:To reduce the quantity of He gas transmitted through a vacuum vessel wall by inserting a layer, in an intermediate section thereof a mica base material is impregnated with a resin, to the plane section of the vacuum vessel wall and a primary curved surface section. CONSTITUTION:Since a mica base material 14 is fitted excellently to a primary curved surface section as seen in a section A and a section C in a vacuum vessel 2, the layer 14 in which the mica base material is impregnated with a resin is inserted into glass base-material glass fiber base-material reinforced resin layers 13. Since the mica base material is difficult to be fitted to the secondary curved surfaces in a section B, a metallic foil 15 may be inserted. Consequently, the layers 14 in which the mica base materials contain the resin are inserted to intermediate sections in plane sections and the primary curved surface sections occupying the greater parts of the surface areas of a liquid He vessel 1 and the wall of the vacuum vessel 2, thus remarkably reducing the quantity of He gas transmitted through the wall of the vessel 2 by the overlapping effect of mica flakes constituting the mica base materials. Accordingly, the degree of vacuum of a vaccum laminated heat-insulating layer is kept at a sufficiently high value for a prolonged term, and the quantity of the internal liquid He being evaporated can be reduced extremely.
