Title: Reduction of sulfate
Inventor: TSUJI RYUSUKE
IPC: F01N3/08
Filed: 1998-09-17
Abstract: PROBLEM TO BE SOLVED: To suppress the discharge of a sulfate component (granular material) even at low temp. area. SOLUTION: A reducing agent is supplied to waste gas and the waste gas is brought into contact with an SOx catalytic reducing catalyst consisting essentially of a transition element to partially oxidize at least the reducing agent to partially oxidized hydrocarbon, and also the sulfate component in the waste gas is reduced and purified with the partially oxidized hydrocarbon. The partially oxidized hydrocarbon is very high in reaction activity and selectively reduces the sulfate component by reacting with the sulfate component in the waste gas. Therefore, the sulfate component is suppressed from being discharged as granular material since the sulfate component is efficiently reduced and discharged as SO2.

Title: Electrostatic charge image developing carrier
Inventor: NAKAMURA MINORU
IPC: G03G9/10
Filed: 1995-10-12
Abstract: PROBLEM TO BE SOLVED: To provide a carrier having excellent environmental stability which does not cause fog on a photoreceptor in a high temp. and high humidity environment by coating the core particles with a resin and specifying each of the static electric resistance and the dynamic current of the carrier. SOLUTION: This carrier is produced by coating core particles with a resin. The static electric resistance is specified to 1×10<8> to 5×10<9> Ω.cm, while the dynamic current is specified to 0.2 to 1.0μA. In this method, the static electric resistance is obtd. by measuring a current when voltage is applied on the carrier which is densely packed and then converting the current into the resistance. The dynamic current is a value which indicates the electric resistance of the carrier which practically forms a magnetic brush in a machine actually used. As for the core particles of the carrier, magnetic particles such as iron, magnetite and ferrite can be used, and especially a ferrite is preferably used. As for the coating resin, a polystyrene resin, poly(meth)acryl resin, etc., can be used.

Title: Probe card and testing device using the same
Inventor: NAKABAYASHI MASAKAZU
IPC: G01R31/28
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To provide a probe card making a burn-in test of a chip in a waver state possible and a testing device using this probe. SOLUTION: A probe card 4 is formed using a quartz glass substrate 5 close in the coefficient of thermal expansion to a silicone wafer with a chip to be a measured object. Accordingly, even if the temperature is changed from normal temperature to high temperature in a burn-in test, the dislocation of a probing pad 6 and a bonding pad 3 is not generated, so that positioning can be performed at normal temperature. Since the quartz glass substrate 5 is transparent, there is no need to open a hole for alignment like a conventional glass epoxy board and the probing pad 6 and the bonding pad 3 are easily aligned. The electrical conduction of the bonding pad 3 becomes more positive by forming an Au ball, excellent in stability and conductivity, on conductive rubber.

Title: Step-out preventing operation control system for magnetic driven pump unit
Inventor: OSHIMA MASAKAZU
IPC: F04B49/10
Filed: 1988-10-20
Abstract: PURPOSE:To make any step-out at restarting due to a short time loss in a power source preventable by detecting a momentary cutoff of the power source, interrupting a power circuit of a motor as long as the specified time, and restarting the motor later than a point of time when the power circuit is reset. CONSTITUTION:When a power source is lost as long as a very short time due to power failure during pumping operation, a relay X1 operates as detecting this momentary cutoff of the power source, and thereby the contact X1b comes ON. With this, an operating coil of a magnetic contactor X2 is excited, turning a contact X2b to ON, and a motor power circuit is forcedly interrupted and simultaneously a self-holding contact X2a comes ON, self-holding the magnetic contactor X2. Consequently, even if the power source is recovered within the power circuit cutoff time, a motor 2 is no longer restarted. When limit time of a time-limit relay PTC elapses and its built-in contact is turned to OFF, the operating coil of the magnetic contactor X2 is demagnetized and the contact X2b comes ON again, so that the motor 2 starts its restarting at this point of time. At this time, since the motor 2 is reset to a magnetic coupling state, any step-out is prevented from occurring.
