If the discharge is accomplished with such construction, the surface potential (a) (partially at about 2000V) initially having a means value of about 300V and considerable roughnesses is discharged to a level of about 200V, after having passed through the conductive brush 8. And, the surface potential is further discharged by means of the corona discharger 1 supplied with an AC voltage until it assumes a uniform value of about 0 volt. Incidentally, the conductive brush may be replaced by conductive rubber rollers.

Title: Electric leakage breaker
Inventor: TODA HARUHISA
IPC: H01H83/02
Filed: 1993-01-20
Abstract: PURPOSE:To make common use of primary conductors of three-pole and four-pole circuit breakers, and shorten the length of the circuit breakers by superposing the primary conductors upon each other, arranging a zero-phase converter in the width center in the four-pole circuit breaker, and arranging it so as to be displaced more than the width center in the three-pole circuit breaker. CONSTITUTION:When primary conductors of an inside pole and an outside pole are superposed upon each other, developing dimensions of the three-pole and four-pole primary conductors can be standardized into two kinds, and an electric power supply - load directional dimension can be shortened. That is, in the primary conductors 8R, 8N and 8S, 8T of the four-pole circuit breaker, the developing dimensions are the same with each other, and the bending directions are opposite to each other, and the primary conductor 8R of the three-pole circuit breaker and the primary conductor 8S of the four-pole circuit breaker are in the same with each other, and 8S and 8T of the three-pole circuit breaker are in the same with 8T and 8N of the four-pole circuit breaker. Thereby, in three-pole and four-pole products of a primary conductor, the developing dimensions are unified and standardized into two kinds of plate conductors. In the four-pole circuit breaker, a zero-phase converter 9 is arranged in the lateral width center of the circuit breaker, and in the three-pole circuit breaker, it is arranged so as to be displaced more than the width center. Thereby, the electric power supply - load directional dimension can be reduced.

Title: Production of microcapsule dispersion
Inventor: IWASAKI HIROSHI
IPC: B01J13/20
Filed: 1979-01-23
Abstract: PURPOSE:To obtain the captioned dispersion effectively removed of aldehyde without imparing performance by introducing inert gas into the microcapsule dispersion having aldehyde polycondensation resin film or aldehyde crosslinked wall films. CONSTITUTION:The microcapsule dispersion having polycondensation resin films or crosslinked wall films such as of formaldehyde is heated to 50 deg.C or more (60- 90 deg.C are best), to which inert gas such as Ar or N2 is introduced. As a result of this, residual aldehyde may be removed with good efficiency and processing time reduced. In addition, the processing of the conventional capsule dispersion which could not withstand water vapor distillation is made possible by the low temperature treatment without impairing the performance of the capsules, thus the microcapsule dispersion which is used for various fields such as pressure-sensitive copying paper and does not contain any residual aldehyde which is considered problem in sanitation control may be obtained.

Title: Method for detecting sludge precipitation state in solid-liquid separation tank
Inventor: IWABORI KEISUKE
IPC: G01N15/04
Filed: 1983-01-20
Abstract: PURPOSE:To make it possible to detect a sludge precipitation state with high reliability regardless of sludge concn., by detecting redox potential at the height position in a solid-liquid separation tank. CONSTITUTION:ORP and pH are almost constant in the upper liquid layer part above a sludge interface but abruptly changed at the sludge interface or therebelow and this changing degree becomes more remarkable as a precipitation time becomes longer. The average value of ORP in the liquid layer is set to (ORP)L while ORP at the arbitrary height position (including the sludge interface) of a sludge layer to (ORP)S to define the index represented by the formula. Because this index value is in almost proportional relation to the precipitation time, the rough calculation of the precipitation time is enabled by calculating the index value and it can be known with high reliability how much sludge is precipitated in a final precipitation basin.

Filed: 1993-01-21
Abstract: PURPOSE:To restrain influence of distortion of a received waveform due to a wraparound wave on the measurement of difference of propagating time so as to improve measuring accuracy. CONSTITUTION:Two sets of a wave transmitter and a wave receiver are organized, ultrasonic wave is propagated by a prescribed distance in the reverse direction of flow in a first set, and in the normal direction of flow in a second set, and the transmitting time point of the second wave transmitter is delayed, so as to receive the respective receiving signals simultaneously at the first and second wave receivers. The delay time is set as the reference delay time tauo, and the flow speed can be obtained because this is the difference between respective propagating times in the normal direction and the reverse direction. Simultaneous receipt of the respective receiving signals is detected based on a mutual correlation coefficient M indicating the degree of coincidence of the respective receiving signals being maximum. When difference between the transmitting trigger signal Tg1 of the first wave transmitter and the transmitting trigger signal Tg2 is tauo, the mutual correlation coefficient M of the receiving signals Y1, Y2 is displayed to be the maximum value Mmax.
