Title: Production of gas turbine rotary blade
Inventor: MORIKAWA MINORU
IPC: C22F3/00
Filed: 1978-03-08
Abstract: PURPOSE: Laser, electron beam, etc. is impinged on about the embedded portion of gas turbine rotary blade having one-directional structure, changing the structure of the surface to nondirectional one, thereby enhancing toughness and heat shock resistance of the material.  
     CONSTITUTION: High energy density generating source 2, or 2' such as laser, electron beam, etc. is arranged at the surface near the embedded portion 4 of gas turbine rotary blade 1 having one-directional structure. The generated energy beam 3, or 3' is used to produce thin molten layer on the surface. When the energy source is moved from the surface, the surface is rapidly cooled by heat transmission from the molten layer to the internal portion, resulting in the formation of nondirectional microcrystal structure. The mechanical property is thus drastically enhanced.

IPC: G01L7/18
Filed: 1979-03-08
Abstract: PURPOSE:To heighten resolving property in the detection of liquid level and enable automatic reading with high accuracy, by using two semiconductor optical units and prisms. CONSTITUTION:Light source lamps 2 and triangular prisms 3 are so placed that they face each other across the liquid level detection parts 8a, 8b of a U-shaped tube 8. Semiconductor optical units 4a, 4b are provided in a vertically symmetric positions over and under each triangular prism 3, one vertex edge of which faces the lamp 2. Liquid level detectors 6a, 6b are thus constituted. The output of each of the detectors 6a, 6b takes a peak value when the liquid level coincides with the height of said vertex edge of the triangular prism 3. Feedback is effected to always place the detectors in the position of the coincidence. The detectors 6a, 6b are moved on screw rods 11a, 11b by pulse motors 10a, 10b. At that time, the positional relation between the liquid levels is determined by a length measuring unit 7. This results in avoiding the influence of the change in the characteristics of the semiconductor optical units due to that in the temperature or the like.

Abstract: PURPOSE:To prevent a deformation and a disconnection of a bonding wire and to enhance reliability and a yield by a method wherein the bonding wire is arranged obliquely with reference to an inflow direction of a sealing resin so as to run along a partial flow direction of the sealing resin flowing inside the cavity. CONSTITUTION:Both bonding wires 12a, 13b are arranged obliquely so as not to be oppose an inflow direction, of a sealing resin, into cavities. Accordingly, both bonding wires 12a, 13b become nearly parallel to a flow direction of the resin flowing inside the cavities and run parallel to a flow of the resin. As a result, a resistance to the flowing resin of the bonding wires 12a, 13b is reduced sharply as compared with a case where, e.g. the bonding wires 12a, 13b are arranged perpendicularly to the inflow direction of the sealing resin. Thereby, even when a thermoplastic resin is adopted and injected at high speed, the bonding wires 12a, 13b are not disconnected by an injection pressure, reliability and yield are enhanced.
