Title: Anisotropic rare earth element bond magnetic powder and its manufacturing method
Inventor: IKEDA HIROSHI
IPC: H01F1/055
Filed: 1997-01-21
Abstract: PROBLEM TO BE SOLVED: To enable obtaining magnetic powder having superior characteristics and higher mechanical strength by mixing a resin, containing a viscosity- adjusting agent which is effective for reducing the resin viscosity with rare earth magnetic particles. SOLUTION: The anisotropic rare earth element bond magnetic powder produced by mixing Sm2 Co17 powder with a viscosity-adjusting agent which is effective for reducing the resin viscosity within the range of 10-15wt.% with respect to the resin. For the resin viscosity, the viscosity prior to containing the viscosity-adjusting agent, i.e., the viscosity at the normal temperature (25 deg.C) of the resin proper exceeds 300 poise, furthermore, the viscosity at the normal temperature (25 deg.C) of the resin to be mixed in the state of containing the viscosity adjusting agent, i.e., immediately before mixing with the Sm2 Co17 , does not exceed 50 poise. Later, the produced bond magnetic is molded in the magnetic field, to produce a magnet molded body.

IPC: B23K1/012
Filed: 1990-01-19
Abstract: PURPOSE:To shorten the transporting distance of a printed wiring board and to miniaturize the device, too, by transporting this board in a preheating zone, a reflow heating-up zone and a reflow zone and providing a means for heating the rear of the board on the reflow heating-up zone with a device wherein hot air is blown and solder is reflowed. CONSTITUTION:The heating means 14 for the rear of the printed wiring board 55 is provided on the reflow heating-up zone 14. Since the printed wiring board transported to the reflow heating-up zone 14 of a solder reflow device made up in this way is heated from the rear side at a temperature higher than the temperature of the surface on which a surface packing component is arranged, the temperature is elevated up satisfying the temperature of the printed wiring board pad part > the temperature at a package IC lead part. In this way, since, at the reflow time, solder, first, wets the printed wiring board pad 54 and spreads, then, wets and joins the package IC lead 52, defective wicking and defective shortage of solder, etc., are removed and good joint by soldering can be obtained and improvement of quality can be expected.

IPC: B64G1/50
Filed: 1998-01-20
Abstract: PROBLEM TO BE SOLVED: To generate the irregular reflection on the skin of a honeycomb sandwich panel and increase the infrared ray radiation dose rate.

Abstract: PURPOSE:To vary the incidence optical axis of a receiving telescope of a laser radar comprising a main mirror and a submirror by a slight angle as desired by enabling the submirror alone to slide at the right to the incidence angle. CONSTITUTION:The solid line (a) indicates the optical path where there is no offset angle to be formed by the optical path of a transmitting telescope and the optical path of a receiving telescope and light coming along the solid line (a) is reflected on a main mirror 1 and condensed at the focal point P1. A submirror 3 is positioned at the point 3a so that the focal point of the submirror 3 coincides with the focal point P1. Light reflected on the main mirror 1 is reflected on the concave surface of the submirror 3 and led to a beam splitter 2 passing through the optical path as indicated by the solid line (b) with which it is mixed with a locally oscillated beam along the optical path (e) for heterodyne detection. When an off-set is generated at an angle alpha, light coming along the optical path (c) is reflected on the main mirror 1 and condensed at the focal point P2. Therefore, the submirror 3 is moved to the point 3b in the direction of the arrow (f) so that the reflected light from the submirror 3 can be led to the splitter 2.

Title: Production of thermosetting polymer blend
Inventor: TANMACHI MASAMI
IPC: C08K5/5425
Filed: 1989-01-17
Abstract: PURPOSE:To obtain a thermosetting polymer blend having excellent heat resistance and mechanical properties by blending a component prepared by mixing EPDM with a vulcanizer with a specified component in the presence of a platinum compound and heating the blend. CONSTITUTION:100 pts.wt. component prepared by mixing an ethylene/propylene/ diene terpolymer (EPDM) with a vulcanizer is blended with 2-60 pts.wt. component comprising two-component liquid silicon compounds capable of addition reaction of formula I and II in the presence of a platinum compound. By heating this blend, the respective components can be crosslinked to form an interpenetrated polymeric network structure. In this way, the purpose blend can be obtained. When the amount of the silicon compound is below 2 pts.wt., there is no effect of improving the heat resistance, and when it is above 60 pts.wt., the tearing strength is low; therefore such conditions are excluded. In the formulas, R1 is CH3, C2H5, C6H5 or the like; and R2 is H, CH3, C2H5, C6H5 or the like.

A pawl surface 2c of a lock pin 2 as a mold opening regulating means is brought into contact with a reference surface of a lock slide 3 of a movable side of a movable side latched means. Here, movement of an urging force of a mold opening spring 6 inhibits movement of a movable side mold 34, and opens only a temporary mold opening amount t1 set to a fixed side mold 35. Resin is foamed. After cooling, a taper shaft 5a is engaged with a taper hole 3b, and the slide 3 moves to a non-latching position. The die is opened. The slide 3 moves to a latching position by a lock slide spring 7 in association with the opening of the mold. A molding is taken out, the mold is again clamped, and continuously molded.
