Filed: 1999-11-19
Abstract: PROBLEM TO BE SOLVED: To provide a method of forming a nonelectrolytic copper plating film on a plastic molded object, which enables stable plating in a short time as compared with the conventional method. SOLUTION: In a method of forming a nonelectrolytic copper plating film on the surface of a plastic molded object by using nonelectrolytic copper plating solution 2, concentration analysis of all the components of the plating solution 2 in a plating bath tank 1 is performed at constant intervals. On the basis of the respective concentration analysis values, the amount equivalent to shortage of each component is supplied to the plating solution 2. Concentration analysis of Cu ion component is performed at least once, during the constant interval. On the basis of concentration analysis value of Cu ion component, almost the same amount of Cu ion component as that of shortage is supplied to the plating solution 2. The amount equivalent to shortage of each component, which is estimated from the shortage of Cu ion component, is supplied at an estimate to the plating solution 2.

Title: Manufacture of positive temperature coefficient thermistor
Inventor: MATSUSHIMA SUSUMU
IPC: C04B35/46
Filed: 1996-12-11
Abstract: PROBLEM TO BE SOLVED: To stabilize a characteristic by adding a dispersant at the time of mixture and further adding thickner so as to uniformly mix in a manufacturing method of a positive temperature coefficient thermistor of a barium titanate type containing lead. SOLUTION: In order to obtain a positive temperature coefficient thermistor of a barium titanate type containing lead, a dispersant is wet-mixed at the time of mixing. In this case, the amount of added dispersant is made about 0.2wt.% to the total weight of a main agent. Further, thickner is added about 5min before the mixture end for preventing separation and settling of mixed slurry. At this time, the amount of addition of thickner is adjusted so as to become about 500cps (B-type viscometer). Thereby, uniform mixed slurry is allowed to be supplied to a later process so as to obtain the positive temperature coefficient thermistor with a stable and excellent characteristic.

Abstract: PURPOSE:To bring all slave sets to a simultaneous notifying state based on the simultaneous notice data by outputting an on-hook signal to a wired line by the simultaneous notice operation of an extension telephone set and outputting the simultaneous notice data to the master set via the wired line. CONSTITUTION:Suppose that a line between a slave set 21 and an extension telephone set 5 is connected and the simultaneous notice operation by an extension telephone set 6, e.g. the operation of a simultaneous notice number by the extension telephone set is implemented, a signal of the simultaneous notice number is inputted to a simultaneous notice controller 7 and the simultaneous notice number signal is inputted to the simultaneous notice controller 7 and a simultaneous notice control signal from the simultaneous notice controller 7 is outputted to an exchange 4 and the on-hook signal is outputted to a line in use among wired lines 3. Thus, the master set 1 interrupts the connection to the busy slave set 21 with the on-hook signal and the master set 1 sends the simultaneous notice data to all salve sets 21-2N via a control channel. Thus, the slave sets 21-2N reach the simultaneous notice reception state.

Abstract: PURPOSE:To improve the degree of freedom in shape, mass productivity, uniformity of holes, etc., by including a thermosetting resin subjected to thermosetting treatment in a prescribed admixture, molding, degreasing and sintering the resultant mixture. CONSTITUTION:An admixture is obtained by mixing raw material powder for sintering such as preburned powder of Ni-Zn ferrite with a binder containing an organic polymeric component such as low-density polyethylene and paraffin, etc. Thermosetting resin powder for forming holes such as a spherical epoxy resin, subjected to thermosetting treatment and having about 0.8mm average grain diameter is added to the admixture and the obtained mixture is kneaded at about 100 deg.C and disintegrated to provide a raw material for forming. The prepared raw material is then molded by injection molding, etc., to afford a molded body, which is subsequently heated to a desired temperature, degreased and sintered at about 1200 deg.C in the air. Thereby, the objective porous sintered compact containing about 59% density of the sintered compact and uniformly dispersed holes of circular cross section is obtained.

Filed: 1988-12-28
Abstract: PURPOSE:To provide the subject quick setting admixture for wet spraying composed of slaked lime, sodium aluminate, sodium carbonate, plaster and alumina cement in a specified weight ratio and having sharp quick setting properties and a short hardening time in a small amount thereof added. CONSTITUTION:With 7-20wt.% slaked lime 10-20wt.% sodium aluminate, 20-30wt.% sodium carbonate, 5-15wt.% plaster and 25-45wt.% alumina cement are blended to produce the objective quick setting admixture for wet spraying. As the sodium aluminate, a material with 1-5 molar ratio of Al2O3/Na2O is preferable and as the alumina cement an ultrafine-powder material with >=6500cm<2>/g grain size (Blaine value) is preferably used. In proportion to the amount of the resultant quick setting admixture for wet spraying added, the setting time is reduced and so control of application thereof at the job site is ready.

Title: Locating equipment of accident section
Inventor: OGAWA MASAHIDE
IPC: G01R31/02
Filed: 1991-11-21
Abstract: PURPOSE:To obtain locating equipment of an accident section which can detect an accident of a short-circuit between power main lines without a false operation. CONSTITUTION:When a ground fault or a short-circuit accident occurs, an induced current due to an accident current flows through an overhead earth-wire 1 and the direction of that current is opposite when it is viewed from an accident point as the boundary. A current transformer 2 detects the current flowing through the overhead earth-wire 1 and gives it to an accident current direction determining device 3. The accident current direction determining device 3 determines the direction of the accident current and holds this current direction. When the rate of a change of the current flowing through the overhead earth-wire is large, a comparator 6 generates an output and makes the result of determination of the accident current direction determining device 3 be outputted. Since the comparator 6 generates the output only when the current changes sharply due to the occurrence of the accident, locating equipment of an accident section generates no output signal in the case when a load current of a power main line becomes large and when the induced current flowing through the overhead earth-wire becomes large, and thus the short-circuit accident can also be detected, in addition to the ground fault accident of a transmission line.

IPC: F24F6/00
Filed: 1987-12-29
Abstract: PURPOSE:To retard a decrease in the sucking-up performance of humidifying plates and enable a humidifier to be matched even to an air conditioner having a small vertical size, by providing each of the humidifying plates with a slit extending upward (inward) from a central lower end part thereof, using one side part of the plate as a water-supplying part, using the other side part as a humidifying part, and providing a water-supplying pipe on the upper side of the water-supplying parts of the humidifying plates. CONSTITUTION:Each humidifying plate 1 is provided with a slit 1c, one side part of the plate is used as a water-supplying part 1a immersed in humidifying water W in a water-supplying tank 6, whereas the other side part is used as a humidifying part 1b, and a water-supplying pipe 2 provided with holes 2a... for dropping humidifying water is provided on the upper side of the water-supplying parts 1a of the humidifying plates 1. Since humidifying water supplied to the humidifying parts 1b is supplied from both the water-supplying tank 6 and the water-supplying pipe 2, the humidifying water dropping from the pipe 2 washes away downward the impurities and hardness components deposited on the water-supplying parts 1a. Further, since the humidifying plate 1 is provided with the water-supplying part 1a and the humidifying part 1b which are arranged laterally, humidifying water moved by capillarity is moved horizontally and therefore favorably without any effects of gravity.
