Title: Frame of machine tool and its reinforcing method
Inventor: TSUBOTA TOSHIO
IPC: B23Q1/01
Filed: 1988-11-11
Abstract: PURPOSE:To obtain a light and rigid structure without damaging property of material of a machine tool body by welding a reinforcing member being different from the machine tool body material in mechanism property to structure members such as bed, column, etc., of the machine tool monolithically. CONSTITUTION:A cross girder 5 of a gantry type boring machine is made of casting material, and provided with partition walls vertically and horizontally to increase its rigidity. A sliding face 11 is formed in front of the cross girder 5. Maximum bending moment is generated in the central part of the cross girder 5, compressive stresses are generated on the upper face 12, and tensile stresses and generated on the underside 13. Thus, in order for the underside 13 to withstand the tensile stresses, a reinforcing member 14 made of I-beam is welded to the underside. For this welding, the reinforcing member 14 is previously buried in a mold, and a molten cast metal is then poured into the mold. By melting heat of the molten cast metal, only the portion adjacent to the surface of the reinforcing member 14, the components of cast iron metal and steel are fused as a unit, and both the metals are welded. When the cast iron and steel are cooled, both metals are firmly welded to form a welded junction 15.

Title: Manufacture of abrasive cloth
Inventor: ITO HAJIME
IPC: B24D11/00
Filed: 1985-12-16
Abstract: PURPOSE:To improve grinding performance of abrasive cloth by forming the abrasive cloth having improved degrees of ventilation and hardness through heating, under no pressure, a porous complex sheet obtained by wet freezing of solution including mainly polyurethane with which a nonwoven fabric made from synthetic fiber having higher melting point than that of polyurethane is impregnated. CONSTITUTION:A nonwoven fabric impregnated with solution including mainly polyurethane is made from synthetic fiber such as polyester etc. having higher melting point than that of polyurethane, and formed in porous complex sheet having minute continuous bubbles by the well-known wet freezing, washing and drying. This sheet is subjected to heat treatment beyond the temperature capable of softening polyurethane under no pressure or very low pressure. In this case, the heating hour and the temperature are adjusted so that the hardness of more than 80 deg. and the ventilation degree of 25cc/cm<2>/sec can be obtained through softening and fusing and partially fusing polyurethane attached to the fiber. As stated above, since hardness is increased up to more than 80 deg. by heating instead of compressing, the ventilation degree can be increased and blinding can be decreased whereby grinding performance for aging is improved.

Title: Manufacture of semiconductor thin film
Inventor: HIRAYAMA HIROYUKI
IPC: H01L21/203
Filed: 1986-11-28
Abstract: PURPOSE:To perform high concentration doping with B with good controllability so as to exceed the limit of solid solution, in doping with B (boron) in an Si molecular beam growing technology, by projecting Ge whose amount is larger than that of the B onto a substrate. CONSTITUTION:The atomic radius of B is 0.98 Angstrom  and smaller than the atomic radius 132 Angstrom  of Si. Therefore, when the B is independently introduced in Si crystals at a high concentration, strain is yielded in a shape the lattice is contracted, and a film having excellent crystal property is not obtained. In order to allevaite the strain of the Si crystals due to the doping with B, the adequate amount of Ge, which is a group IV element and has a larger radius than those of B and Si, is simultaneously introduced so that the strain due to the doping of the B is allevaited. The crystal property of an epitaxial film, in which the B is doped at a high concentration, is improved by simultaneously doping the B and the Ge, which is more than the amount of B. The doping exceeding the limit of the solid solution of the B can be performed. A higher activating rate can be also obtained.

Abstract: PURPOSE:To simplify the titled receiver and to make the size small by providing a filter bank to a high frequency amplifier stage so as to utilize it for the detection of an interference wave in a frequency hopping system receiver. CONSTITUTION:A signal from an antenna 10 is inputted to a filter bank 13 comprising high frequency band pass filters 1a - 1n and high frequency amplifiers 2a - 2n. A level detector 3 detects each output level of the amplifiers 2a - 2n and stores it. A switch 4 supplies a desired high frequency signal to a mixer 5 by using a switching signal of a hopping pattern generator 9. Since the output frequency of a local oscillator 8 is switched by the pattern generator 9, the reception signal is amplified by an intermediate wave amplifier 6 and demodulated by a demodulator 7. A signal other than the desired channel given by the pattern generator 9 is fed via the switch 4 to the discriminator 11, where the presence of an interference wave is discriminated.
