Then a zirconium precursor solution is prepared by treating zirconium tetranormalbutoxide in the same way as that for the titanium. Thereafter, a PZT (ferroelectric zirconate titanate) is obtained by mixing both of the precursor solutions together. Then a PZT sol of fine particles having different particle diameters is obtained by mixing butanol and polyvinyl butyral in the PZT precursor solution and precipitating and condensing PZT by agitating the mixed solution. When the sol is applied to a platinum electrode and baked, a PZT film in which small-diameter particles get in gaps between large-diameter particles is formed.

IPC: G01R1/073
Filed: 1992-07-06
Abstract: PURPOSE:To make an operation confirmation and conduction check device applicable without any relation to shapes of a printed wiring board, electronic parts and a conductive pattern by constituting a matrix-like probe with a plurality of probes. CONSTITUTION:A probe 1 consists of an insulation tube 2 incorporating a coil spring 3 and a contact needle 4 penetrating it. The upper projection part 4B of the contact needle 4 is connected to a measurement part with a signal line and a lower projection part 4C is brought into contact with a derivation leg part 6A of electronic parts 6 mounted on a printed wiring board 5. Thereby operation and conduction of the board 5 is confirmed with the measurement part. A plurality of the probes 1 are arranged in the form of a matrix and a matrix-like probe is constituted and pressed on the surface of the board 5. For instance, the projection part 4C of the and left-hand needle 4 comes into contact with the derivation leg part 6A and is conducted to a signal line. But, since the right-hand needle 4 does not come into contact with the other conduction part, it does not conduct electricity and there is no conduction leakage in the right-hand and left-hand needles 4 because the insulation tube 2 is isolated. Accordingly, confirmation of operation and conduction is possible without any relation to the form of the board 5 and the like.

Title: Kana/kanji conversion method
Inventor: KIDO MITSUGI
IPC: G06F17/22
Filed: 1990-07-06
Abstract: PURPOSE:To reduce a case to be converted into a dictionary coincident word not expected by an input operator and correcting operation by referring a cancel word dictionary registering the reading of a converted character string and that of a determined character string as a pair. CONSTITUTION:The 'KANA' (Japanese syllabary)/'KANJI' (Chinese character) converter is provided with a converted character string register 5 for storing a 'KANA'/'KANJI' converted result, a reconversion processing part 6 for executing correcting operation and a determined character string register 7 for storing a determined character string to be a reconverted result. The reading of a converted character string obtained immediately after conversion is compared with that of a determined character string, and when both the reading results are different from each other, the reading of the converted character string and that of the determined character string are registered in the cancel word dictionary 10. At the time of succeeding 'KANA'/'KANJI' conversion, the dictionary 10 is referred at first, and when the reading of an input character string concides with that of the converted character string in the cancel words, the input character string is not treated as a conversion candidate and the precedently adopted reading of the corresponding determined character string is treated as a conversion candidate. Consequently, conversion from an input word into a word not expected by an operator can be reduced.
