Title: Solution and method for etching thin copper foil
Inventor: YAJIMA AKIMASA
IPC: C23F1/18
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To execute uniform etching to a circuit board even if the etching rate is reduced to the value suitable for thin copper foil by allowing the soln. to contain ferrous chloride and a copper-noncorrosive inorganic salt as effective components. SOLUTION: Since the etching soln. contains the copper-noncorrosive inorganic salt as an effective component, even if the concn. of ferrous chloride is reduced, it does not erode an etching resist, little copper remains between circuits, and the control of the concn. of the etching soln. is easy. Moreover, the etching rate can be made slower. As the copper-noncorrosive inorganic salt, sodium chloride, calcium chloride or the like can be considered, but, among them, chlorides having high solubility to water are preferable. Its concn. is suitably controlled to 5 to 40 wt.%. The etching soln. is preferably mixed with a small amt. of hydrochloric acid by (about 0.05 to 5 wt.%) as well.

Abstract: PROBLEM TO BE SOLVED: To continuously control the rotating speed of a rotary blade with the change of the water level in a washing and spinning tub by continuously increasing the rotating speed of the rotary blade at a fixed proportion according to the detection data obtained from a water supply data detecting means to reach a designated rotating speed. SOLUTION: When a water supply valve 18 is turned on to start the supply of water and water is supplied to the minimum level, the level is detected by a water level detecting means so that a motor 8 starts to rotate at a rotating speed r1. When the water is supplied to the low water level, the rotating speed of the motor comes to r2. At this time, by an inverter control device, the output frequency is continuously increased at a preset fixed proportion to the output frequency for giving the rotating speed when a pulsator 7 starts to rotate, the rotating speed of the pulsator 7 is continuously increased to reach a designated rotating speed, whereby according to the rise of the water level in a washing and spinning tub 6, the rotating speed of the pulsator 7 is continuously increased at a fixed proportion.

Filed: 1998-03-03
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of such a problem that a burrlike part of adhesive which is solidified in a joint part after being pushed out of the joint parts is dropped into an oil pan. SOLUTION: When members 2, 3 are joined, an excess of an adhesive applied to end parts of parts 2a, 3a to be joined, is pushed out of the end parts. Of this adhesive, an adhesive part 8 pushed out toward opposite ends of the parts 2a, 3a to be joined is retained in cut-outs 6, 7, thereby it is possible to prevent the adhesive 8 from being pushed out from the opposite ends of the parts 2a, 3a to be joined. Thus, the adhesive 8 which is solidified so as to have a burr-like shape, can be prevented from being dropped into an oil pan, thereby it is possible to prevent oil form being mingled therein with foreign matter.

Abstract: PURPOSE:To prevent a code discriminating margin in a comparator from being largely affected with the deviation of a serial resistor, and to improve the yield of products by printing-forming a pull-up resistor inside a first or a second membrane sheet where the serial resistor is formed. CONSTITUTION:A pull-up resistor Rj as well as a serial resistor Rij is formed on the same membrane sheet 22 in the same manufacturing process. In such a method, even when the resistance values of the serial resistor Rij and the pull-up resistor Rj are dispersed from a standard value, the dispersion in Rij and Rj is made comparatively smaller, and the input voltage error of the comparator is made smaller. For this reason the level discriminating margin in the comparator becomes larger, and the yield of the products can be improved.
