Title: Method for coating surface of bead of weld metal and its vicinity
Inventor: MATONO MICHIO
IPC: B05D7/14
Filed: 1982-07-15
Abstract: PURPOSE:To perform elimination or reduction of labor in the step of constructing a welded structure, by depositing a weld metal onto a parent metal by gas- shielded welding, applying thermosetting resin-contg. paint onto the surface of the bead of the weld metal, etc., and curing said paint with residual weld heat. CONSTITUTION:During a cooling step after a weld metal 4 is deposited onto a parent metal 2 by gas-shielded welding, an applicator nozzle 7 is let run following the advancing direction D of an arc, so that paint 8 containing thermosetting resin such as melamine one is sprayed through the nozzle 7 and applied onto the surface 4a of the bead and its vicinity. Thereafter the paint 8 is cured using residual weld heat remaining in said weld metal 4 and its vicinity, to form a coating film 9 at the surface 4a of the bead, etc. Since this method enables to form the coating film 9 immediately after the welding, complicated brushing works such as the removal of hygroscopic components in advance of the coating can be eliminated.

Title: Light strain actuator
Inventor: OGATA SHIRO
IPC: G12B1/00
Filed: 1990-05-11
Abstract: PURPOSE:To make small the size of a light strain actuator and integrate by providing a light waveguide layer on the surface or the boundary of light strain materials. CONSTITUTION:A light strain actuator 1 consists of a light strain element 4 of bimorph type made of a pair of plates 2, 3 bonded together on which surfaces light waveguide layers 5 are formed. One side plate 2 of the element 4 is made of a light strain material which expands with light energy and the other side plate 3, of a light strain material which contracts with light energy. Layers 5 are formed on the whole outer surface of the plates 2 and 3. One end of the element 4 is fixed perpendicularly to a fixing part 6 and light fiber 7 is photo-coupled at the end of the light receiver end of both layers 5. When light is led into the layers 5 through both light fibers 7, the light energy is spread in the layers 5 and is absorbed in the element 4. Thus, if one plate 2 expands and the other plate 3 contracts, then the light strain actuator 1 bows and the free end 8 displaces.

Title: Method for detoxicating waste gas
Inventor: YAMADA MAYA
IPC: B01J20/02
Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To miniaturize a facility and save the cost by removing arsine by bringing a waste gas into contact with a solid removing agent which selectively removes arsine and then carrying out combustion detoxification treatment of phosphine by introducing the resultant waste gas to flames of a burner. SOLUTION: A waste gas 4 containing a large amount of phosphine and a small amount of arsine is brought into contact with a combustion of a mixture containing one of manganese oxides such as Mn3 O4 , Mn2 O3 , MnO2 , etc., and one of iron oxides such as FeO, Fe3 O4 , Fe2 O3 , or one selected from one group and a plurality of oxides selected from the other group, or a plurality of oxides selected from each group. In an initial period of the contact detoxification treatment, phosphine and arsine are together adsorbed in the composition and detoxicated. Then, phosphine reaches in adsorption saturated state in an early stage and after the breakthrough, only arsine is selectively adsorbed and removed.  Since the gas 5 does not evolves hazardous arsenic even by combustion treatment after the gas is brought into contact with the composition, detoxification treatment of a waste gas 4 containing a large amount of phosphine and a small amount of arsenic is efficiently and safely treated.

Title: Air-fuel ratio control device of internal combustion engine
Inventor: YOSHIZAWA KEITA
IPC: F02D41/14
Filed: 1994-06-03
Abstract: PURPOSE:To enhance the accuracy of the air-fuel ratio control while an oxygen sensor is not in the activated state. CONSTITUTION:The air-fuel ratio of mixture gas to be actually sucked by an engine before an oxygen sensor (A) equipped with a heater is activated, is sensed (B) through utilizion of the output characteristics of the oxygen sensor, and the clamp value of the air-fuel ratio feedback correction factor alpha is set on the basis of the result from sensing, and therefore it is possible to approach the air-fuel ratio, which is obtained in the feed-forward control (C) before the oxygen sensor is activated, still nearer the target air-fuel ratio. This enables suppressing degradation of the engine stability which may be caused by the ratio being dislocated to the rich side to result in worsening of the fuel consuming rate/exhaust characteristics or dislocateed to the lean side to result in misfire etc., in the condition that the oxygen sensor is not in the activated state.
