Filed: 1996-08-26
Abstract: PROBLEM TO BE SOLVED: To prevent writing failure in advance by storing not only data but also data writing count in an EEPROM (Erasable Programmable ROM) and by prohibiting writing exceeding the writing guaranteeing count. SOLUTION: Every time when a microprocessor 2 writes data to an EEPROM 3 that is a non-volatile memory where data can be erased and written electrically, it updates and stores an accumulative value N of a data writing count, compares a value (N+1) obtained by adding 1 to the accumulative value N of the data writing count with a writing guaranteeing count M that is peculiar to the EEPROM 3 before writing new data, and permits new data to be written in the case of (N+1)<M and generates a warning and disables new data to be written in the case of (N+1)>=M, thus avoiding a writing mistake due to writing exceeding the life limit of the EEPROM 3 and operating a microcomputer system 1 stably.

Filed: 1984-10-26
Abstract: PURPOSE:To recover and reutilize zinc contained in a waste liq. and to reduce the material consumption by neutralizing a waste acidic zinc electroplating liq. with sodium carbonate to deposit basic zinc carbonate which is washed with water and supplied to a plating bath as a zinc source. CONSTITUTION:A waste acidic bath zinc electroplating liq. is neutralyzed with Na2CO3 or Na2CO3 and NaOH to deposit basic zinc carbonate. After the deposited crystal is washed with water and the water-soluble impurities are removed, the crystal in a slurry or the crystal which is separated and dried into solid powder is supplied to a plating bath and reutilized as a zinc source. Before the waste plating liq. is neutralized, an oxidizing agent and then zinc powder are previously added to deposit dissolved impurities of heavy metals having lower ionization tendency than zinc and to remove the impurities. Zinc can be recovered in high purity and reutilized by this method, and the cost of treating the waste can be reduced.

Abstract: PURPOSE:To furnish woody material with high dimensional stability and its manufacture by a method wherein woody particles are impregnated with polyethers and polymerization catalyst, treated by heating, coated with bonding agent, scattered over a mold, packed and finally pressed. CONSTITUTION:Because woody particles are impregnated with polyethers, the dimensions of the woody particles stabilize and consequently the dimensional stability of woody material such as particle board, which is manufactured by forming the woody particles by means of bonding agent into sheet is also improved. In addition, because the woody particles are impregnated with the polyethers together with polymerization catalyst and, after that, treated by heating, the efflux of the polyethers due to the absorption of water content and the consequent loss of dimensional stabilization effect are prevented from occurring. The woody particles consists of shavings, grinds and the like of wood and have no limitation as for the kind of wood, size, form and moisture content of particle, and the like. After being impregnated, the woody particles are dried. The moisture content of the particles is normally conditioned to 3-8%, though it depends to bonding agent. The dried particles are coated with bonding agent with a sizing application of the like. The forming of the particles is performed by hot-pressing the particles, after being coated with bonding agent, scattered over a flat plate mold or the like and packed.
