Reflowing is conducted so that plated materials are heated in the atmosphere or a reduction atmosphere to melt plated films and then the plated materials are rapidly cooled. A tin- bismus alloy of an uniform composition is produced by reflowing and rapid cooling. It is preferable that a temp. of the object to be plated in reflowing is <=300 deg.C and rapid cooling is done within 5 sec after a tin plated film starts to melt.

Title: Nonslippery footwear sole
Inventor: MORIOKA MITSUO
IPC: A43B13/22
Filed: 1991-03-20
Abstract: PURPOSE:To substantially prevent the dislodgment of abrasive grains by embedding chips formed by binding the abrasive grains with a binder into the ground contact part of a footwear sole body and exposing these chips to the ground contact surface. CONSTITUTION:The shoesole body 1 is rubber and the chips 2, 3 are moldings formed by bonding the abrasive grains with a phenolic resin. The chips 2, 3 are sized to enter the inside of projecting parts 4, 5 patterned to take the antislipping of the rear surface of the shoesole body 1 into consideration. The process for production is executed by charging the chips 2, 3 into the recessed parts forming the projecting parts 4, 5 of the shoesole body 1 in metallic molds for vulcanization and charging unvulcanized rubber into the molds, then vulcanizing the rubber. The resulted nonslippery shoesole 6 is exposed with the chips 2, 3 in positions deviating toward the rear surface side. The chips 2, 3 are powerfully held in the footwear sole body and the dislodement of the abrasive grains is drastically decreased by the binder as compared to heretofore. In addition, the next abrasive grains are exposed even if the exposed abrasive grains are dislodged and worn down and, therefore, the effect of maintaining the nonslippery effect over a long period of time is obtd.

Abstract: PURPOSE:To use a clock of a low speed, and to improve an operating speed of a demodulator by executing a processing by using a clock signal of a speed of two times of a modulating speed. CONSTITUTION:An analog signal A is quantized to a digital signal of (k) bits by a clock signal B of two times of a clock signal (fs) being a modulating speed of the signal A, in an A/D converter 4. This (k) bit quantizing signal C is brought to a sampling delay at a speed of (fs) in a delayed FF (DFF) 5 of (k) bits. In this case, an (fs) clock signal D which has divided the clock signal B of a speed of 2fs, whose phase is synchronized with an (fs) reference clock signal, into two by a frequency divider 6 is impressed to a clock input CK of the DFF 5. A sampling delay signal E by the DFF 5 and the (k) bit quantizing signal C are multiplied by a multiplier 7, and its result F becomes a phase difference signal output.

Abstract: PURPOSE: To provide a distributed constant circuit within the small volume having a long electric length as designed by folding zigzag a flexible printed circuit board composed of two layers of a signal line layer and a ground layer for each fixed length and convolving the signal layer and the ground layer while inverting the front side and the rear side. CONSTITUTION: Closely checking a section C, where an EPC is folded zigzag and dropped from a hill to a dale, and the section where it is moved upward from the dale to the hill, it is found that continuous signal lines 11 at both sections face each other. More closely checking the place where a front face cover coat layer 5 at the section and a front face ground layer 2a at a section D are interposed between these confronted signal lines 11, these signal lines 11 are shielded each other by the ground layer 2a and do not directly face each other. Therefore, electrostatic coupling between signal lines is eliminated. This is similarly established even concerning a section E dropped from the hill, where the continuous signal lines 11 face each other, to the dale and a section F raised from the dale to the hill as well.  Therefore, the distributed constant circuit having the required electric length can be easily provided as designed.
