Filed: 1985-09-09
Abstract: PURPOSE:To make even the blank having bad workability the bucket product of good quality easily by co-axially fix the blank in the shape corresponding to a formed part with the forming die in the inner face shape of a bucket formed part and by spinning the rotary blank with the specified pressure of a moving roll. CONSTITUTION:The austenitic stainless steel blank (a) having stainless high durability subjected to blank layout in the shape corresponding to a formed part is coaxially fixed with the press of a tail stock 2 to the forming die 1 in the inner face shape of a bucket formed part. The spinning is performed with the transfer of a roll 3 by turning the blank (a) with the forming die 1. In this case, the number of revolutions is taken about 300-500rev/min so that the blank (a) is sufficiently elongated and no wrinkle nor waving are caused, and the pressure per point of the roll 3 is taken more than about 1,500kg so as to elongate the blank (a) sufficiently. The mouth part peripheral edge of the formed partially semifinished part (a) thereof is reinforced with curling to make the bucket product of good shape and quality. The spinning by human power can therefore be executed easily even in case of the blank of bad workability.

Abstract: PURPOSE: To provide a method for calculating the power flow in an AC-DC link system receiving AC power and consuming it by DC power. CONSTITUTION: First, a rated value of a DC link point voltage is initialized (s101). Based on this link point voltage and a DC load, a DC system power flow is calculated to obtain a link point power flow and bus voltage (s102).

Based on this load and voltage in an AC link point set by an operating pattern or the like, an AC system power flow is calculated (s104).  Link point voltage by a result of power flow calculation is compared with the DC link point voltage given in the s102 (s105), and when a deviation is a fixed value or more, the DC link point voltage is corrected to a value obtained in the s104 (s106), and correction in repeated untill changing the DC link point voltage is reduced.

Title: Manufacture of bump
Inventor: MORI KATSUNOBU
IPC: H01L21/60
Filed: 1989-07-31
Abstract: PURPOSE:To make it possible to connect a bump to a wiring board at a low temperature of about 200 deg.C and to prevent the collapse of the bump due to the flow of solder by changing the composition of a solder layer provided on the upper part of a barrier metal so that the melting point becomes low in the vicinity of the upper layer part of the solder layer, and performing plating. CONSTITUTION:For example, alkanol-sulfate-based plating liquid is used. With this liquid, the composition of deposited material can be changed by changing the composition of the plating liquid, current density and the circulating speed of the plating liquid. A solder layer 7 having a high melting point and an alloy ratio of Pb and Sn at, e.g. 60%: 40%, is formed on a barrier metal 4. A solder layer 6 having a lower melting point and an alloy ratio of Pb and Sn at, e.g. 38%: 62%, is formed on the surface of the layer 7. Even if the solder on the surface of the bump is melted, the solder in the inside is not melted. Therefore, the bump is not collapsed. Since only the composition of the plating liquid, the current density, the circulation speed of the plating liquid and the like are changed in the solder plating steps, the steps are simplified.
