Title: Removal of nickel in potassium hydroxide
Inventor: KAWAGUCHI TOSHIHIRO
IPC: C01D1/28
Filed: 1998-12-28
Abstract: PROBLEM TO BE SOLVED: To provide a method for removing nickel in potassium hydroxide, enabling the easy removal of the nickel in the potassium hydroxide in a short time to give the highly pure potassium hydroxide by filtering an aqueous potassium hydroxide solution containing the nickel by means of a filtration device pre-coated with activated carbon. SOLUTION: By the method, the nickel eluted on the concentration of the potassium hydroxide and contained in a concentration of 0.1 ppm order can efficiently be removed to give a concentration of 0.01 ppm order. The activated carbon used as the pre-coating agent comprises porous carbon which has a large adsorption capacity and is obtained by carbonizing coconut shells, timber, charcoal, lignite, etc. In particular, activated carbon obtained from the coconut shells has an excellent nickel-adsorbing capacity. When a filtration device used herein is a filtration device pre-coated with the activated carbon, the filtration is especially not limited.  The concentration of the potassium hydroxide containing the nickel, the amount of the used activated carbon, the flow rate and volume of the aqueous potassium hydroxide solution passed through the filtration device, etc. are especially not limited, but, for example, 100-2,000 g/m2 of coconut shell activated carbon is used for removing 0.1 ppm of nickel in a 50% aqueous potassium hydroxide solution.

Title: Wave transmitting and receiving device for water ultrasonic wave using ringlike ceramic
Inventor: ISHIDA KIYASU
IPC: G01S15/96
Filed: 1999-12-03
Abstract: PROBLEM TO BE SOLVED: To miniaturize a wave transmitting and receiving device because a main body of a detector in an ultrasonic detector for measuring depth of sea water or water or detecting a fish school can be considerably miniaturized owing to the appearance of semiconductor but the wave transmitting and receiving device is not miniaturized yet at present, although there are various ultrasonic detectors and they are mounted on a small boat for detection recently. SOLUTION: Most of wave transmitting and receiving devices used in practical use at present use a flat plate type ceramic vibrator. In this type vibrator, its outside diameter cannot be greatly reduced because an ultrasonic wave is radiated from a plane part. However, in a cylindrical type ceramic vibrator, its outside diameter can be considerably reduced because an ultrasonic wave is radiated from the whole cylindrical surface. Furthermore, it is possible to provide the considerably miniaturized wave transmitting and receiving device when compared with the conventional device because its machine conversion efficiency is large.
