Abstract: NEW MATERIAL:The tropolone derivative of formula I (R<1> is H or lower alkyl; R<2> is aryl or substituted aryl; R<3> is substituted aryl or substituted or unsubstituted heterocyclic group). EXAMPLE:3-[ alpha-( 2-Hydroxy-6-isopropyltropon-3-yl )-4-methoxybenzyl]-4- hydroxy coumarin. USE:It has antitumor activity and is useful as a medicinal drug. PREPARATION:The compound of formula I can be produced by reacting a monotropolone derivative of formula II (R<4> is lower alkyl) with a compound of formula R<3>-H in the presence or absence of a solvent under heating. The amount of the compound of formula R<3>-H is equimolar or slightly excess to the compound of formula II. The reaction is carried out e.g. at 120-130 deg.C in the absence of solvent, or in the case of using a solvent, it is carried out under refluxing at 100-180 deg.C in the presence of a catalyst.

Title: Infrared image pickup device
Inventor: NASU YOSHINORI
IPC: H04N5/228
Filed: 1988-03-10
Abstract: PURPOSE:To reduce the influence of the wiring in a Dewar by transmitting the output signal of an image pickup device after converting the output signal into a low impedance via an impedance converting circuit set in the Dewar. CONSTITUTION:An impedance converting circuit 3 which is thermally isolated form an image pickup device 1 is set close to this device 1 in a Dewar 2. As a result, the wiring can be shortened between the device 1 and the circuit 3. The circuit 3 iputs the output signal of the device 1 and performs the conversion of impedance to outputs the signal to a signal detecting circuit 6 at a low impedance. A wiring 20 has its small section area so as to suppress the heat conducted to the device 1 from the circuit 3.

Title: Conductive paste and laminated ceramic electronic part
Inventor: SATO YUICHI
IPC: H01G4/12
Filed: 1995-03-16
Abstract: PURPOSE: To reduce the occurrence of delamination in using Ag/Pb paste, by containing at least one kind of a metal of Ti, V, Cr, Zr, Nb, and Mo, etc. of less 1wt.% in metallic powder. CONSTITUTION: In metallic powder having a main component of silver and palladium, at least one kind of a metal of a Ti, V, Cr, Zr, Nb, Mo, Ta, W, Si, and Ge of less 1wt.% is added. This can sinter and contract silver/palladium on a higher temperature side to restrain the occurrence of delamination.
