Abstract: A laser welding structure includes a lead, a conductive member, and a welding part. The lead has a nickel plating layer and is made of copper or copper alloy. The conductive member is joined with the lead and is made of copper or copper alloy. The welding part is formed by a laser welding so as to join the lead and the conductive member. An end portion of the welding part has a rounded convex shape.

Abstract: A thick film circuit board that can be produced at a low cost, a method of producing the same, and an integrated circuit device. A first thick film circuit board has conducting layers of a copper-containing conductor fired at not higher than 750° C., and includes conducting portions formed by using a silver-containing conductor. A second thick film circuit board has conductors that are formed in the through holes so as to close the openings of at least the one side thereof. The thick film circuit board is produced at a low cost and suppresses a drop in electric conductivity when it is in use.

Abstract: An odor-emitting port is provided in a housing member composed mainly of an inorganic material. An odorous material is contained in the housing member, and the odor-emitting port is sealed with a low-melting metal to constitute a heat-sensitive odor-emitting component. In this heat-sensitive odor-emitting component, as soon as the temperature of a heat generation site has reached a predetermined value, the low-melting metal is instantaneously melted down to open the odor-emitting port through which the odorous material contained in the housing member is immediately spread around the odor-emitting component. Therefore, the odor-emitting component is highly sensitive to temperature. Further, since the housing member is formed of an inorganic material, the long-term stability can be improved.

Abstract: An advance transaction processing method in a transaction processing system for conducting transaction by inserting a card as a recording medium into an automatic teller machine by a user and carrying out input operation by the user, involves registering transaction assigning data for assigning transaction operation to be conducted by the user, a transaction restriction condition, and card identifying data on the card carried by the user; allowing an internal storage or a storage of the central processing unit connected to the automatic teller machine to store a transaction-operational procedure by using the transaction assigning data as a key for search; confirming as to whether the transaction restriction condition is satisfied, when the card is inserted into the automatic teller machine; reading the transaction-operational procedure by using the transaction assigning data recorded on the card as the key for search; and allowing the automatic teller machine to execute the processing for the transaction in a

Abstract: This invention relates to fungicidal novel derivatives of 6-(3,5-dichlorophenyl)perhydroimidazo[5,1-b]thiazole derivative. These compounds may be used for controlling fungal infection, especially in agriculture.

C. is 2 to 10 centipoises.

Abstract: Chemicals containing an effective amount of homopolymers of dialkylaminoalkyl acrylate derivatives or dialkylaminoalkyl methacrylate derivatives or copolymers of such derivatives with ethylenically unsaturated monomers copolymerizable therewith. The chemicals exhibit a remarkable effect of preventing agricultural plants from being infected with plant virus diseases. A method for controlling the plant virus diseases is also described.

Abstract: A.DELTA..sup.1 - tetrahydrophthalic anhydride is reacted with an amine in the presence of lower fatty acid. Alternatively N-(4-hydroxyphenyl)-.DELTA..sup.1 -tetrahydrophthalimide or a salt thereof is reacted with an aralkyl halide. A N-substituted-.DELTA..sup.1 -tetrahydrophthalimide compound having herbicidal activity is produced. This compound has the formula ##EQU1## wherein R' is naphthyl; phenyl; phenyl substituted by 1-3 substituents selected from the group consisting of halogen, nitro, cyano, thiocyano, carboxyl, haloalkyl, lower alkyl and alkylthio; --CH.sub.2 Y wherein Y is phenyl, naphthyl or phenyl substituted by 1-5 substituents selected from the group consisting of halogen, nitro, lower alkyl and lower alkoxyl; or ##SPC1##Wherein Z is phenyl, naphthyl, or phenyl substituted by at least one substituent selected from the group consisting of halogen, nitro, lower alkyl and lower alkoxyl.
