Title: Catalyst structural body and deodorizing device having catalyst structural body
Inventor: OSHIMA KOJI
IPC: B01D53/86
Filed: 1998-05-12
Abstract: PROBLEM TO BE SOLVED: To obtain a catalyst structural body which is safe and can cope with various kinds of odorous components and in which a catalyst can be permanently used by generating discharge and using at least one of discharge energy, UV energy, heat and ozone to carry out the decomposition of harmful substances, sterilization, decomposition of NOx , synthesis or the like. SOLUTION: In this catalyst structural body, a voltage is applied from an AC power supply 5 to between feeders 3 to generate discharge in small gaps 8 formed between electrodes 2 and a catalyst body 1. In this case the discharge comprising the stream of electrons reaches the inside of the inner part and its discharge energy or the UV energy, heat, ozone or the like produced in the case of the discharge are used to decompose harmful substances present in the catalyst space and to regenerate the catalyst. Then, the flatness of the contact face of the electrode 4 with the catalyst body 1 is not specically limited, however, a face with a little rough surface is preferable than the complete flatness.  Since discharge is easily produced when the distance between the electrode 4 and the catalyst body 1 is shorter, it is preferable to bring the electrode 4 into contact with the catalyst body 1 so that lots of minute gaps 8 are present.

Title: Wire cut electric discharge machine
Inventor: YAMAMOTO MASAHIRO
IPC: B23H7/04
Filed: 1986-06-25
Abstract: PURPOSE:To enable the improvement of machining efficiency by connecting a plurality of switching elements in parallel for a main current circuit and changing the number of the parallel circuits with drive circuits of a parallel element group according to an instruction from a control device depending upon a discharge condition between electrodes. CONSTITUTION:When a gap 1 between electrodes of an electric discharge machine has become unstable, the output of a detecting device 2 therefor fluctuates and a control device 12 gives an instruction corresponding to the fluctuation, thereby stopping the operation of a drive circuit 6d. Then, as the parallel reactance value of a main circuit increases, a main circuit current changes to a reduced current. Furthermore, when the unstable condition has been interrupted and the operation of a drive circuit 6c has stopped due to the instruction from the control device 12, the parallel reactance value gives a further rise and the main circuit current gives a drop. Also, When the unstable condition continues, the operation of drive circuits 6b and 6a stops in turn, thereby reducing the current value. In this state, if a short- circuit current condition has appeared without restoring a stable condition even after the stop of all the circuits 6a-6d, the control device 12 gives an instruction for actuating the circuits 6a-6d at rest, thereby running a small amount of currents through the main circuit, and a large amount of currents after the restoration of the stable condition.

IPC: H04L69/40
Filed: 1995-06-14
Abstract: PURPOSE: To provide a line monitoring system capable of transmitting performance information to a center side by using facility to support a superframe format. CONSTITUTION: A central terminal 1, when detecting step out in reception from a remote terminal, sends out a synchronous alarm to the remote terminal 12. Line quality information is generated by a far end PM(performance) detection circuit 27, etc., based on a signal received by the remote terminal 12. The remote terminal 12 uses all the sync bits of a frame format to be transferred to a central terminal side as ordinary synchronization information while the synchronous alarm arrives from the central terminal side. When no more synchronous alarm arrives, the line quality information is transmitted to the central terminal 11 by using a part (F12 bit) of the sync bit.
