Title: Arithmetic unit for self-correlation coefficient
Inventor: UKITA MASAAKI
IPC: G06F17/15
Filed: 1985-09-05
Abstract: PURPOSE:To increase the processing speed with an arithmetic unit for self- correlation coefficient by changing the arithmetic order and reducing the data reading frequency at both real number and imaginary number parts of a complex digital signal against a RAM. CONSTITUTION:A complex digital signal is obtained from a complex signal underwent the phase wave detection through the A/D conversion. The values of the real number and imaginary number parts of the complex digital signal are stored in a RAM 2. An address counter part 4 designates successively the reading addresses to the RAM 2. A register part 12 latches the values of both real and imaginary number parts of the complex digital signal which receives designation of an address and is read out through the part 4. A multiplier 18 multiplies the values of both real number and imaginary number parts latched by the part 12. An accumulating means 20 accumulates successively to outputs of the multiplier 18. In such a constitution, the arithmetic time of a self- correlation coefficient is shortened and the arithmetic result of the average frequency is immediately obtained. This also reduces the CPU load.

Title: Method for preventing seamless steel pipe from wall thickness deviation
Inventor: AIYAMA SHIGEKI
IPC: B21B19/06
Filed: 1981-12-07
Abstract: PURPOSE:To remarkably reduce the generation of the wall thickness deviation of a seamless steel pipe, by rolling said pipe at a rolling speed kept away from the inherent frequency of a mandrel bar, in rolling a seamless pipe by a skew rolling mill. CONSTITUTION:The inherent frequency (ni) of a mandrel bar is expressed by the equationI, where li is the distance from the skew roll center to bar-steadiers, lambda1: intrinsic value 3.927, E: 2.1X10<6>kg/cm<2>, I: pi/64 (D<4>B-D<4>1), A: pit (DB-t), gamma: 7.8X10<-3>kg/cm<2>, DB: outside diameter cm of a mandrel bar, t: wall thickness cm of the mandrel bar, D1: internal diameter cm of the mandrel bar. Further, the equation II is applicable by setting the rolling speed as: Vcm/ACC, efficiency: alpha, plug diameter: Dpcm, (n): the number of revolutions transmitted to the mandrel bar, and the rolling speed Vi which causes the generation of resonance is expressed by the equation III. Accordingly, the inherent frequency (ni) of the mandrel bar is avoided by determining the rolling speed by avoiding Vi in the equation III, thus the resonance is prevented and the generation of wall thickness deviation is reduced.

Title: Apparatus and method for mounting conductive ball
Inventor: SAKAI TADAHIKO
IPC: H01L21/60
Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To prevent an adhesive liq. stored in a reservoir from volatilizing contained volatile components to increase the viscosity of the liq. when the liq. is deposited on a conductive ball sucked to the lower face of a mounting head to mount the ball on an electrode of a work. SOLUTION: A first squeegee 17 is slid on the flat upper face a of a reservoir to recover an tacky liq. 4 on this face a to the side of the reservoir 15. The liq. 4 becomes a lump with reduced surface area, resulting in little volatilizing of the volatile components and no increase of the liq. viscosity. A mounting head 22 comes to deposit the lig. 4 to the ball 1 at its lower face, and the squeegee 17 is retreated upward and second squeegee 18 is lowered and slid with a fixed gap G from the upper face to develop the liq. 4 thin on the upper face a.

Title: Solar heat water heater
Inventor: KAWAKAMI AKIO
IPC: F24J2/44
Filed: 1982-11-09
Abstract: PURPOSE:To efficiently collect solar heat, and to increase the quantity of heat collected by a solar water heater, by decreasing the circulating resistance of a heating medium by making the sectional area of a heat collecting tube large in the upper part of a heat collecting plate, while by decreasing the sectional area of a heat collecting tube in the lower part of a heat collecting plate, and by taking the length of the tube in which liquid heating medium remains long and the sectional area of a heat collecting tube large in the upper part of a heat collecting plate. CONSTITUTION:The diameter of a heat collecting tube 18 in the part about one third from its bottom, which is located in the lower part of a heat collecting plate 16, is reduced to decrease the sectional area of a tube. Accordingly, it is not necessary to feed a large quantity of heating medium into a circulating circuit 22, but at least one third over the length of a heat collecting tube 18 from its bottom is enough to be filled with liquid. When the solar heat is supplied to this part and the heating medium rises up along the heat collecting tube 18 in the flow of two phases of gas and liquid, the heat collecting tube 18 can absorb evaporating latent heat from the heat collecting plate 16 over the length of the tube 18, without causing dry-out. On the other hand, the diameter of about two third of a heat collecting tube 18 from its top is made large to increase the sectional area of the tube, as a result, the resistance loss of a gasified heating medium can be made small when the heating medium passes through the upper part of a heat collecting tube 18.

Filed: 1998-07-13
Abstract: PROBLEM TO BE SOLVED: To realize the shortening of the axial dimension by forming a shallow annular recessed part along the pressure receiving side of the circumferential edge of a piston body to provide a thin wall part on the circumferential edge, forming the thin wall part into cover form, and fixing a seal lip thereto. SOLUTION: In the circumferential edge part 2 of a piston body 1, an annular recessed part 12 having a small dimension ΔT is formed along the pressure receiving side (pressure chamber 5 side), and a thin wall part 13 is provided on the circumferential edge part 2. The axial dimension A1 on the circumferential side of a piston 4 itself is reduced by ΔT, and the dimension B1 from the deep end surface 8b to the low pressure end side closer to the circumference of the piston body 1 is also reduced by ΔT. The axial dimension A1 of the piston 4 itself can be reduced, although the reduction is only the dimension ΔT of zero point several mm to about 3 mm, without loosing the strength, elastic repelling force, flexibility and sealing property of a seal lip 3 or while keeping the wall thickness T0 (thickness dimension) of the sheet metal piston body 1 as it is.

Title: Cooling device of molten bath level meter coil in electromagnetic mold
Inventor: NISHIO TERUTSUNE
IPC: B22D11/16
Filed: 1984-09-21
Abstract: PURPOSE:To improve the durability of a molten bath level meter coil in an electromagnetic mold (EMB coil) by providing a coil box of a material quality which is non-magnetic and high in a high temperature strength, for surrounding the EMB coil, so that it is insulated from a mold copper plate. CONSTITUTION:When a cooling air is supplied into a coil box 1 by a purge use pipeline 6, air in the box 1 is pushed by the cooling air and exhausted to the outside from holes 2, 3, and the inside of the box 1 is filled with the cooling air. An EMB coil 7 is in this cooling air and always cooled. A leading- out part of a lead wire 8 connected to the EMB coil 7, and a connecting part of the lead wire 8 and a cable are apt to cause a fault by heat or water, but in case when they are placed in the pipeline 6, they are cooled and dried by the cooling air supplied into the pipeline 6. Also, in case when they are placed outside of the pipeline 6, they are cooled and dried by the cooling air which blows out of the hole 2 after having filled the inside of the box 1, therefore, no insulating failure is generated, and the durability is improved.
