Title: Accommodation device for honeycomb construction
Inventor: YONEMURA MASAAKI
IPC: F01N3/28
Filed: 1984-10-19
Abstract: PURPOSE:To prevent failure as well as to enhance the sealing performance by accommodating a honeycomb construction in a container with a thermo- expansive packing interposed, covering the ends of the packing with a cloth consisting of heat resistance fibers, and by allowing these covered ends to protrude from the end face of the honeycomb construction. CONSTITUTION:A honeycomb construction 1 is surrounded by a thermo- expansive packing 3, whose end part is covered with a silica cloth 8 as a cloth consisting of heat resistant fibers, and is accommodated in a metal container 2. That part of packing 3 covered with said silica cloth 8 is protruded from the end face of the honeycomb construction 1 and butted to a flange 5 so that the honeycomb construction 1 does not directly contact the flange 5. This hinders the thermo-expansive packing 3 from touching the exhaust gas stream directly to prevent failure due to blowing-off. Also the covered part protruding from the end face of honeycomb construction 1 will enhance the sealing effect.

The optical axis direction of the light irradiator 23 in the objective lens displacement detecting means 32 is directed in the focus direction, and for the light-receiving surface of the photodetector 24, the size is set so that most of the light beam can be made insident regardless of the divergency of the light beam of the light irradiator 23 by a movement in the focus direction. As a result, the displacement detection in the tracking direction of the objective 6 cannot be influenced by the drive in the focus direction. Thus, the pure displacement in the tracking direction can be detected, and the start of the accurate access can be brought forward.

Title: Production of alloy powder for rare earth magnet
Inventor: SAGUCHI AKIHIKO
IPC: H01F1/06
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To reduce the activating time of an alloy till hydrogen absorption, to reduce dispersion in pulverizability therein and to increase the efficiency of the production by subjecting an R-T-B series alloy thin piece to immersing treatment into an acid aq. soln., subjecting it to washing and drying to execute surface modification and thereafter executing hydropulverization. SOLUTION: The alloy raw material for an R-T-B series permanent magnet is produced by subjecting electrolytic iron-ferroboron alloy-rare earth metal to high-frequency melting and rapidly solidifying the alloy molten metal by a single roll metal or a twin roll method. The thin piece of this alloy raw material is subjected to immersing treatment into an acid aq. soln., which is subjected to washing and drying to activate the surface of the alloy. Next, it is housed in an absorbable and exhaustible vessel and is allowed to execute hydrogen absorption under >=0.10 kg/cm<2> hydrogen pressure, and hydropulverization is performed. Since the base and main phase base are exposed on the surface of the alloy subjected to the pickling, the probability that hydrogen molecules adsorb into the alloy base increases, and the activating time, i.e., the hydrogen absorption starting time is reduced.  The amt. of hydrogen atoms to be dispersed into the boundaries and grains after the adsorption increases.

Title: Oxygen sensor
Inventor: MORI RENTARO
IPC: G01N27/409
Filed: 1996-08-21
Abstract: PROBLEM TO BE SOLVED: To enhance the heat resistance and improve the responsiveness by forming an electrode on the surface of a base into a laminating structure of particles in which the surface of metal oxide particle is metalized with noble metal. SOLUTION: Since an electrode has a laminated structure of particles in which the surface of metal oxide particle 6 is metalized with noble metal, porosity can be enhanced. Further, since the specific surface area of the electrode can be increased, the interface between gas and electrode can be increased, and when an oxygen ion conductive solid electrolyte is used as the particle 6, the interface between solid electrolyte and gas can be also increased. The side of a primary particle is set to several tens μm or less, whereby penetration of large impurities into the electrode can be prevented. On the other hand, when the particle is too small, the porosity can not be attained by the mutual close contact of particles, and oxygen is sealed within the electrode so that it can not response to the concentration change of the gas.  The laminated structure of the primary particle can be formed on a base 3, and it is formed by mixing the noble metal particle in an organic solvent, immersing a sensor element surface into the solution, and sintering the noble metal particles.

After that, plants or seeds of a ficus-pumila-L 20 are stored in an unglazed vegetation bed rock body manufactured in advance together with the soil 60, and the vegetation bed rock 10 is inserted into the hole 40 mentioned above. As a result, the ficus- pumila-L 20 creeps a stone wall in a short state of height, so that the surface layer of the slope 70 is prevented from sliding down while greening the slope 70. Besides, its stem is strong against pulling force, so that the surface layer of the slope 70 is further prevented from sliding down. It is an evergreen tree, so that greening can be executed in all seasons.

Abstract: PURPOSE:To detect a fault without supplying a power to an external load and to prevent damage from being generated due to the operation of the external load by detecting the switching state of a switch part based on the receiving state of a signal reception means. CONSTITUTION:A high frequency signal generating part 17 is provided, and also, a high frequency transformers 18, 19a, and 19b are mounted on switch cables A and B. And a high frequency signal from the high frequency signal generating part 17 is transmitted to the switch cables A and B by the high frequency transformers 18, 19a, and 19b, and the switching states of the switch parts 13-a and 13-b can be detected based on the reception states of the high frequency signals in the switching cables A and B. Thus, the switching state of a contact can be detected by the reception state of the high frequency signal from the high frequency signal generating part 17 in spite of an external power source. In such a way, it is possible to detect the presence/absence of the fault without operating the external load, and to prevent detecting accuracy from being affected by the magnitude of the external power source. Also, since the high frequency signal with a frequency different from that of the external power source is used in the detection of the fault, no malfunction occurs, and also, since the switching state of the contact can be detected in a non-contact state with the switching cable, the detection can be performed in an insulated state from a heavy electric circuit.
