Title: Regeneration of nitrogen dioxide absorbent
Inventor: FUKUJU ATSUSHI
IPC: B01D53/56
Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To provide a nitrogen dioxide absorbent maintaining NO2-absorbing capability for 1 year or longer without replacement. SOLUTION: This nitrogen dioxide absorbent comprises a porous carrier and a basic amino acid together with an organic amine compound and/or an alkaline hydroxide deposited on the carrier. The used absorbent deteriorated by nitrogen dioxide absorption is washed with water to elute the basic aminoacid together with the organic amine compound and/or the alkaline hydroxide simultaneously with absorbed nitrogen dioxide into the washing water. After being dried, together with an organic amine compound and/or the alkaline hydroxide, the basic aminoacid is again deposited on the support of the resultant absorbent. Consequently, the used absorbed can repeatedly be regenerated and used without deteriorating the absorption capability.

IPC: H02H3/26
Filed: 1990-11-28
Abstract: PURPOSE:To elevate reliability by providing transmission fault detecting functions in every transmission route, and preventing the changeover to the transmission route where the transmission fault is detected. CONSTITUTION:If transmission fault occurs on the side of a down signal A route, a transmission fault detection circuit 13 detects the transmission inferiority, and it outputs a transmission fault signal 16 and an A route transmission infault signal 21 to a transmission route changeover circuit 14. The transmission route changeover circuit 14, due to the materialization of the condition of an AND circuit 211, sets the flip flop circuit 224 through an on delay timer 231 and an OR circuit 221, and a route changeover circuit 24 gets on 1 level from 0 level, and performs the changeover from A route to B route. At the same time, it sends out a route changeover signal 25 to the counterpart terminal, and the counterpart terminal also seeks to perform the changeover from A route to B route, but with the counterpart terminal, the B route is in maintenance and inspection, and B route transmission fault is being detected, so the route changeover is locked, and it can be operated with A route intact.

Filed: 1988-12-23
Abstract: PURPOSE:To prevent the traveling of a cage in the door opened state by installing a rectifier in parallel to an opening/closing means for opening and closing the conduction electric current for the conduction of an opening door side driving element and connecting the anode side of the rectifier with the output side of a closing door side driving element and connections the cathode side with the output side of the opening door side driving element. CONSTITUTION:Even if the cage of an elevator is in traveling or in stop, an opening/ closing means 19 opens a door outside the door opening/closing permission range, and closes the door under other conditions. In the state where the opening/closing means 19 is in opened state, a rectifier 18 is connected in parallel with the opening/ closing means, setting an anode on a closing door side driving element 13 side and a cathode on an opening door side driving element 11 side, in order to suppress the conduction of electric current into the door opening side driving element 11. Therefore, during the traveling or stop of the cage, and outside the door opening/closing permission range, the opening/closing means 19 is in opening sate, and the rectifier 18 is in the conduction cut-off state, and the electric current does not flow in the door opening direction in an electric motor 20, even if the opening door side driving element 11 erroneously operates or is ON-operated because of troubles.

Title: Die for pipe making by hot extrusion
Inventor: YAMADERA YOSHIMI
IPC: C22C38/24
Filed: 1994-11-30
Abstract: PURPOSE: To prolong the life of the above die longer than the life of a costly die formed by build-up welding of a hardly hardenable material by forming a decarburized layer in the front layer part of the inside surface of a material contact part from at least an approach part to a bearing part. CONSTITUTION: The layer thickness and surface hardness of the decarburized layer have a proportional relation. Namely, the surface hardness degrades as the decarburized layer is thicker. If the layer thickness is small, plastically flowable parts decrease and, therefore, the effect of prolonging the life is low. The layer thickness is specified to >=0.2mm in this viewpoint. If, conversely, the layer thickness is too large, a problem arises in the die strength and the deformation, etc., of the die arise. The upper limit of the layer thickness is, therefore, confined to <=1.5mm. A heat treatment for forming the decarburized layer is executed prior to a heat treatment of hardening and tempering in order to form the decarburized layer.  Namely, while the distinct decarburization takes place at a temp. above the A1 transformation point, the tempering is executed at a temp. below the A1 transformation point.

Abstract: PROBLEM TO BE SOLVED: To enable a lid member and a container main body to be engaged with each other while a sealing characteristic is being kept between a flange part and the lid device before and after a seal film is removed from the flange part of the container main body. SOLUTION: An engaging sidewall 21 of a lid device 20 is installed at a flange part of a container main body 10. In the case that a seal film 32 is heat sealed on the flange part 15, the flange part 15 is engaged between a first protrusion 22a and a second protrusion 22b, and an outer circumference 32a of the seal film 32 is held between the flange part 15 and the engaging sidewall 21. In the case that the seal film 32 is peeled from the flange part 15, the flange 15 is engaged between the first protrusion 22a and a circumferential edge plate 23.  An inner diameter L2 of the engaging sidewall 21 between the first protrusion 22a and the circumferential edge plate 23 is smaller than an inner diameter L1 of the engaging sidewall 21 between the first protrusion 22a and the circumferential edge plate 23, so that the flange part 15 engaged between the first protrusion 22a and the circumferential edge plate 23 and the engaging side wall 21 are closely contacted with each other to keep a close sealing characteristic therebetween.

Title: Feeding voltage application circuit
Inventor: KAJIWARA SHINJI
IPC: H04B3/46
Filed: 1989-12-14
Abstract: PURPOSE:To inhibit feeding from other feeding power supply while power is fed from one feeding power supply to a monitor line by providing a current block means monitoring a balanced pair cable and inhibiting the current flowing to a relay during voltage application even when a voltage is given. CONSTITUTION:A contact 3 of a relay 2 is provided between a feeding power supply 10 and a balanced pair cable and a relay 2 is provided with a current block means 4 monitoring the cable voltage and inhibiting current flowing to the relay 2 during voltage application even when a voltage V is applied. While power is fed from one feeding power supply to, e.g. a monitor line of a cable, even when a voltage V is applied to the relay 2 for power feeding from other power supply 10 to close a contact 3, the means 4 inhibits a current flowing to the relay 2. Thus, the contact 3 is not closed and the voltage is not applied from the power supply 10. Since the feeding power supplies 10 of both ends or the like do not apply voltage to the monitor circuit simultaneously, the occurrence of a fault is prevented.
