Title: Steel plate for welded can
Inventor: HARA TOMIHIRO
IPC: C21D8/02
Filed: 1980-08-01
Abstract: PURPOSE:To obtain a surface-treated steel plate which is superior in a high speed mush welding and is suited for weight reduction of cans by an extremely simple and highly productive method by cold rolling a steel plate wherein a proper amount of a tin-plating layer is alloyed perfectly with iron. CONSTITUTION:Tin is plated umiformly at about 0.01-2.0g/m<2> (per one side surface in the case of both side plating) on the clean surface of a steel plate. Below  this lower limit, the amount of tin is not enough for uniform coating, and the amounts above the upper limit are uneconomical and are undesirable in workability  of final products and the like. Next, in order to turn this plating layer perfectly into an Sn-Fe alloy, the steel plate is heated ususlly for about 2-60 seconds at  300-800 deg.C in a nonoxidating atmosphere. Annealing is carried out simultaneously with this heating or annealing is carried out prior to the in plating. The alloying  reaches the entire part of the plating layer, and the Fe/Sn atom ratio of the surface  layer is kept at about 40-80% for the sake of the final surface characteristics having undergone subsequent cold rolling and working. Thence, this steel sheet is  further cold-rolled at 5-40% drafts to a steel sheet of, for example, around 0.16mm.  thickness.

Title: Phase-jitter measuring apparatus
Inventor: YOSHIDA NAOMASA
IPC: G01R29/00
Filed: 1988-04-26
Abstract: PURPOSE:To make it possible to measure phase jitter in a total digital mode, by obtaining the time domain data of the phase errors of a digital-phase controlled oscillator (VCO). CONSTITUTION:A VCO 20 estimates data thetai which represent the advance of the phase of a signal whose phase is to be followed at a time width T. An averaging circuit 1 is composed of an integrator and a divider and obtains the data thetai. An integrator 4 outputs the integrated value of the inputted data up to that time every time the new data are inputted. The data outputted from the integrator 4 are averaged in an averaging circuit 5. Thus, the data DELTAthetaare obtained. The data outputted from the integrator 4 are delayed by a time T in a delay circuit 6. The data DELTAtheta are subtracted from the delayed data in a subtractor 7. Thus, the time domain data of the phase errors are obtained. At this time, the mean square of the time domain data is obtained by using a square operation circuit 8 and an averaging circuit 9. The root of the obtained mean square is obtained with a root operating circuit 10. Thus, the data of the phase jitter are obtained.

Title: Metallic plate and container for induction heating apparatus and manufacture thereof
Inventor: INASAWA SHINJI
IPC: H05B6/12
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration in heat generating property, formability, corrosion resistance, etc., by forming a conductive layer having a specified rupture elongation value in part of external surface of aluminum or aluminum alloy material. SOLUTION: Part of external surface of a heating metal plate is formed with an electric conductive layer serving as a heat generating layer. The conductive layer is specified to have an elongation value of 1% to 30% at rupture. On the other hand, the aluminum plate used is a soft material and exhibits elongation of 30% to 50% at rupture. Therefore, if a conductive material combined with aluminum has an elongation of less than 1%, the conductive material develops defects such as cracks. As a result, forming process is difficult, and the material has a very small impact strength. The cracks in the conductive layer may lead to gap corrosion occurring on boundary surfaces of different metals.  Furthermore, although the conductive layer has to be placed in alternating magnetic field to induce an eddy current in the conductive layer, heat generating property is remarkably reduced as the eddy current is interrupted by the cracks.

Title: Sodium mist remover
Inventor: YAMAMOTO HAJIME
IPC: B01D1/00
Filed: 1979-08-22
Abstract: PURPOSE: To efficiently remove the sodium mist by a method wherein impactors having nozzles and buffle plates are installed in a metal container and cover gas is flowed at a specified rate or higher.  
     CONSTITUTION: In a sodium mist remove for a sodium coolant type fast reactor, the metal container 10 is provided, in its circulation channel, with a mist trap 9 having plural steps of the impactors consisting of the buffle 11 and the nozzles 12. When the cover gas 2 is flowed into the mist trap 9, the gas flow speeds up at the part of nozzles 12 and is jetted to the buffle plates 11. This causes the mist 7 in the gas to inertially collide against the buffle plates 11 and be collected. Thus, the process prevents clogging due to sodium in the trap and ensures a stable gas flow.

Title: Linear pattern forming method for molded part
Inventor: OGATA MASAHIRO
IPC: C04B41/91
Filed: 1991-05-10
Abstract: PURPOSE:To form a clean linear pattern on the pattern forming section of a molded part by fitting a masking member on the pattern forming section of the molded part, grinding the pattern forming section along the end periphery of the masking member, and removing the masking member after grinding has been processed. CONSTITUTION:When a linear pattern is to be formed on the surface of a molded part A, a masking member 13 is fitted onto a space close to a pattern forming section 12. In the second place, the pattern forming section 12 is ground along the masking member 13 by a grinding means 14. After grinding has been processed, the masking member 13 is removed, a linear pattern equivalent to the periphery of the masking member 13 is formed on the pattern forming section 12. A grinding belt is pressed with pressure only on an upper flat section close to the end periphery of the masking member and a curved section where no masking member is fitted on. Since grinding on the molded part is processed in such a way that the curved section is cut off, a clean linear pattern can thereby be formed along the end periphery of the masking member.
