Title: Waterproofing of submersible thermally spraying gun and submersible thermally spraying gun
Inventor: KON TOSHIHARU
IPC: C23C4/12
Filed: 1994-07-23
Abstract: PURPOSE:To easily and perfectly prevent infiltration of water into a submersible thermally spraying gun by increasing the pressure in this gun higher than the water pressure, thereby preventing the infiltration of the water into the gun. CONSTITUTION:A nozzle 30 is fixed via a nozzle fixing cap 29 to the front end of a gun body 28 of the thermally spraying gun 1. Plural shielding flow ejection ports 19 are disposed around an atomizing air ejection port 31 in the central part thereof. Compressed air is supplied from an air hose 15 to inject the thermally spraying jet flow. High-pressure air is supplied through a small hole 39 into the thermally spraying gun 1 to make the pressure in the gun 1 higher than the water pressure, by which the infiltration of the water into the gun 29 is prevented. As a result, the thermally spraying gun is easily and completely subjected to waterproofing even if the thermally spraying gun has parts of which the hermetic sealing is infeasible or difficult.

Title: Sprueless disk mold
Inventor: ASAI IKUO
IPC: B29C45/28
Filed: 1990-07-20
Abstract: PURPOSE:To save resin and to shorten the time of a production cycle by providing a heating means around a reservoir of resin and fitting a plunger energized by a spring to an introduction port side and equipped with a male cutter in the reservoir of resin. CONSTITUTION:Molds 1, 2 are clamped and both a piston 32 of a cutter and the male cutter 20a of a plunger 20 are allowed to abut in the opposite faces. The nozzle chip 8 of an injection molding machine is allowed to abut against the introduction part 1a of the fixed mole 1. When molten resin is injected to the reservoir 15 of resin, one part of resin filled in the reservoir 15 of resin pushes forth the plunger 20 and is filled into a cavity 3 through a formed gate 16. After resin is solidified or cooled, the solenoid 42 of a hydraulic circuit is magnetized. The piston 32 of the cutter is moved to the male cutter 20a side to perform gate cut. A molded form is taken out by performing mold opening. Since the resin in the reservoir 15 is overheated by a heating means 19, this resin is not solidified and sprue is not generated. Since the sprue is absent, the material is saved by the amount thereof. The time of a production cycle can be shortened because the interval of mold opening is favorably made narrow.

Abstract: PURPOSE:To improve response performance and permit stress to be controlled, by controlling the flow-rate of combustion assisting fuel by selecting the smaller signal among the both signals supplied from a steam-pressure controlling means and a steam-pressure variation-rate controlling means, in a gas-steam turbine combined type generation set. CONSTITUTION:The sum of each output electric power of a gas turbine and a steam turbine is calculated in an adder 190, and is compared with a set value in a comparator 191, and the main steam pressure signal corresponding to the deviation is obtained through conversion in a converter 181, and an aimed control value A196 is obtained in an adder 192 from the actual steam pressure, and is input into a lower-value priority circuit 186.

When a combustion assist control excluding apparatus 195 is made unavailable, the smaller signal among the both signals A and B is set as the valve opening degree signal 24 of a combustion assisting fuel flow-rate controlling valve. Thus, the improved response performance is obtained, and the proper stress control is permitted.

Title: Material strength evaluation method of metal material and method and device for diffusion layer thickness evaluation
Inventor: KUBO TAKAHIRO
IPC: G01N27/72
Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To make possible evaluation of material strength by measuring conductivity of precipitation strengthened metal material strengthened by precipitating a precipitation phase in a parent phase and obtaining a mutual boundary length based on relationship between a predetermined conductivity and the mutual boundary length of the precipitation phase. SOLUTION: For a precipitation strengthened nickel group ultra-alloy IN 738 LC, a precipitation phase of a NI3 AI phase is dispersed in a parent phase of a Ni solid solution body, material strength of a material in which a fine precipitation phase is dispersed evenly is generally strong. This conductivity is measured by a tetra terminal method. The conductivity of this material varies depending upon a mutual boundary length L of the precipitation phase. That is, when the mutual boundary length L is long the conductivity is lowered, and when the mutual boundary length L is short the conductivity is higher. Assuming that an average mutual particle size of the precipitation phase is d and that a distance between crystal granules is λ, the result is L=πd/λ<2> and d/λ<2> has correlation with a creep strength.  Consequently, the mutual boundary length L is obtained from correlation database predetermined by measuring conductivity and converted into d/λ<2> , making it possible to estimate the creep strength.

Title: Bonding wire for semiconductor element
Inventor: TOYOFUKU KATSUYUKI
IPC: H01L21/60
Filed: 1990-07-20
Abstract: PURPOSE:To make strength of a neck part equivalent to that of a busbar or more and to improve the drawing strength of wire by coating an outer peripheral surface of a core which consists of a specified metal or an alloy thereof with a coating material which consists of a specified metal or an alloy thereof. CONSTITUTION:A coating material 1 which consists of high purity Pt or Pt alloy is clad on a core 2 which consists of high purity Ag or Ag alloy. Then, wire drawing processing is performed. After annealing treatment is performed in the middle of the processing, a busbar of a specified wire diameter is formed by wire drawing processing. Furthermore, stress is removed. In the constitution, a neck part is thermally affected during ball formation, and an outer peripheral part of the core and an inner peripheral part of a coating member of the neck part mutually diffuse; thereby, a diffusion layer consisting of Ag-Pt alloy is formed and strength of the neck part is improved compared with a busbar without a diffusion layer. Therefore, it is possible to make strength of the neck part equivalent to that of the busbar or more. It is thereby possible to obtain thinner bonding wire, to reduce bonding pitch accordingly and to realize high density package of an LSI.

Title: Pin hole correcting method for definition pattern filter
Inventor: TACHIBANA SHINYA
IPC: G09F9/30
Filed: 1989-07-26
Abstract: PURPOSE:To set retouch processes of three colors to a single process of an achromatic color, and also, to prevent the generation of a color mixture caused by a protrusion by executing a retouch using ink being an achromatic color and having intermediate transmittivity to a pin hole. CONSTITUTION:Pin holes 3r, 3g and 3b generated at the time point when printing of red, green and blue patterns 2R, 2G and 2B of a definition pattern filter 1 is finished, are corrected by executing a retouch process only once by one color of ink 4 being an achromatic color, and also, having intermediate transmittivity. In this case, in a very narrow vision range, a man's visibility characteristic is scarce in the discriminating capacity of each color, only a luminance difference is detected chiefly, and by matching the transmittivity of the ink 4, it does not occur that one picture element containing the pin holes 3r, 3g and 3b is sensed as a different color. In such a way, a single retouch process is enough and the production efficiency is improved, and also, even if a protrusion is generated at the time of process, no color mixture is generated since ink of an achromatic color is used.
