IPC: H01H1/025
Filed: 1982-05-28
Abstract: PURPOSE:To obtain a composite electrical contact material for sealing consisting of a prescribed percentage of calcium nitride and the balance copper, superior to a conventional copper-nitride type composite electrical contact material in contact performance, and having especially stable low contact resistance. CONSTITUTION:This composite electrical contact material for sealing contains 1-15wt% calcium nitride in copper. Copper powder is mixed with calcium nitride powder in a V-type mixer for a prescribed time.

Title: Melting furnace for waste incineration residue and melting method thereof
Inventor: NAKAO TSUYOSHI
IPC: F23G5/00
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To enable stable operation with the prevention of a short circuiting between an electrode and a melt salt layer by dividing an upper space of the body of a melting furnace into a supply space and an exhaust space with a middle partition wall to allow efficient volatilization of a melt salt produced. SOLUTION: The space above the top surface of a melt slag layer 7 in a furnace tank (furnace body) 1 is divided by a middle partition wall 6 into a supply space 9 (internal atmosphere temperature of furnace: 600 deg.C or lower) on the side of a supply port 3 and an exhaust space 10 (internal atmosphere temperature of furnace: 1,300 deg.C or higher) on the side of an exhaust port 10. On the maximum limit basis, one electrode 2 is arranged on the side of the supply space 3 with respect to the middle partition wall 6 and the other electrode 2 is arranged on the side of the exhaust space 10. The incineration residue fed from a support port 3 expands onto the top surface of a melt slag but not beyond the partition wall 6 and is allowed to stay in the supply space 9.  Thus, as the top surface of the melt slag is covered with none of the incineration residue in the exhaust space 10, the exhaust space 10 boosts up to a high temperature by heat from the melt slag to volatilize a melt salt thereby allowing avoiding of the shorcircuiting between the melt salt and the electrode 2.

CONSTITUTION:The monostable multivibrators MM1, MM2 are connected in cascade and CR time constant circuits 1, 2 having time constants tau1, tau2 are connected respectively to them and a sink pulse P is inputted to the vibrator MM1. Thus, the trailing (leading) of the sink pulse P is taken as a trigger, the time constant of tau1 of the vibrator MM1 and the 1st threshold level decides a time T1, the output of the vibrator MM1 having a leading is triggered at the time T1, and the vibrator MM2 decides a time T2 by using the time constant tau2 and the 2nd threshold level. Then a burst gate pulse (d) having a pulse posi tion at the time T1 and whose pulse width is expressed as W=T2-T1 is obtained as the output of the vibrator MM2.

IPC: C07C50/12
Filed: 1982-05-31
Abstract: PURPOSE:To improve the purity of the collected compound in the collection of the titled compound from a reaction product gas obtained by the catalytic vapor- phase oxidation of naphthalene, using an aqueous medium containing maleic acid in the presence of a molecular oxygen, by carrying out the collection in the presence of iron ions and copper ions in said medium. CONSTITUTION:A reaction mixture gas containing naphthoquinone and phthalic anhydride and obtained by the vapor-phase catalytic oxidation of naphthalene, is brought into contact with an aqueous medium containing maleic acid in the presence of molecular oxygen to collect the naphthoquinone and phthalic anhydride. In the above process, the purity of the collected naphthoquinone can be improved by adding 10-10,000, especially 50-1,000ppm each of iron ion and copper ion originated from inorganic or organic salts to said aqueous medium. The process has additional advantages; for example, the amount of waste water from the naphthoquinone collection process can be decreased by recycling the waste water of the vapor-phase catalytic oxidation process, and the polymerization of the naphthoquinone in the collecting apparatus can be prevented.

Title: Method and device for automatic adjusting of sludge concentration in sewage treating chamber
Inventor: MIHASHI KAORU
IPC: C02F3/12
Filed: 1987-04-13
Abstract: PURPOSE:To maintain specified sludge microorganism by withdrawing sludge from a sewage treating chamber and storing the same in a sludge concn. adjusting chamber when the propagation rate of the sludge microorganisms in said chamber is high and replenishing the sludge into the sewage treating chamber from the sludge concn. adjusting chamber when the concn. is decreased by self digestion. CONSTITUTION:A sludge transferring mechanism 6 is operated when a transmission type optical sensor 14 mounted in the sewage treating chamber 1 or a circulation circuit 2 for the treating water decides that the sludge concn. in the chamber 1 is higher than the prescribed concn. The high-concn. sludge in the chamber 1 is then transferred into the sludge concn. adjusting chamber 5 by the operation of the mechanism 6 and the intermittent or continuous aeration is executed in the chamber 5 at the time other than the concn. adjusting time. In addition, the supernatant in the chamber 5 is made to flow over said chamber into the chamber 1 to dilute the sludge in the chamber 1 to the lower concn. A sludge returning mechanism 9 is operated when the above-mentioned sensor decides that the sludge concn. in the chamber 1 is lower than the prescribed concn. The settle sludge in the chamber 5 is returned into the chamber 1 by the operation of the mechanism 9 to increase the concn. of the sludge in the chamber 1. As a result, the always specified sludge microorganism are maintained in the treating water and the amt. of the excess sludge is decreased.

Filed: 1995-03-23
Abstract: PURPOSE: To prevent malfunction due to delay of the determination of an address line by making the diffusion capacity value of the source region of the transistors whose sources are connected in common larger than a specified capacity value. CONSTITUTION: The device has two transistors 11c, 12c whose sources are connected in common and one of which is definitely made on by an address signal and, in addition, precharge transistors 13C, 14C which bring the drain of each transistor to the high level. Two transistors 17c, 18c connected in series whose drains are connected to the sources of transistors, 11c, 12c and which are each brought to the on/off state by an address signal are connected.
