Filed: 1984-10-09
Abstract: PURPOSE:To use a flash light emitting device properly by providing an exposure correcting means which selects a higher brightness decision level as photographic range information from a range measuring circuit shows shorter range. CONSTITUTION:The light measurement output of the light measuring means consisting of a photodetecting element 1, diode 2, and operational amplifier 3 is compared with brightness decision levels by a comparator 27 to decide whether the flash light emitting device 29 is usable or not. In this case, the brightness decision level generating means consisting of constant current circuits 23 and 24 and diodes 25 and 26 generate plural brightness decision levels. Then, the exposure correcting means consisting of a reference power source, 18, comparator 19, D.FF 20, resistance 21, and switching transistor 22 selects a higher brightness decision level as the photographic range information from the range measuring circuit 17 shows shorter range. Consequently, daylight synchronized flash photography is performed more properly and the flash light emitting device is prevented from performing unnecessary light emission.

Abstract: PROBLEM TO BE SOLVED: To prevent the development of cracks in a ferrite substrate for an MIC isolator. SOLUTION: In the MIC isolator, a thick strip conductor 2 and an ground conductor 4 are formed on the wide surface of a soft ferrite board 1 and a microstrip line having a three-terminal junction part is constituted of these three components, i.e., the ferrite board 1 and the conductors 2, 4, on the center part of the board 1.

Title: Speech input method and recording medium
Inventor: TANAKA MASAHIDE
IPC: G10L15/183
Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To automatically insert a punctuation mark into a natural flow of dictation by discriminating a predetermined specific character string from character strings recognized according to an inputted speech and adding one punctuation mark. SOLUTION: When speech input is started (S2), a KANA(Japanese syllabary) character string is discriminated (S3) corresponding to the progress of speech. A clause structure is analyzed from the KANA character string (S4) and KANJI (Chiniese character) automatic conversion is performed by clauses (S5). Then the necessity of punctuation mark addition is analyzed from the character string recognized according to the inputted speech and a punctuation mark is automatically added (S6). In concrete, it is decided that the ending of a clause is a predetermined specific character or character string and one punctuation mark is added. Then it is confirmed whether or not the speech input ends (S7).  Consequently, even when the speech input of a document is performed along a natural flow of dictation at the time of the creation of the document, the document is punctuated properly with punctuation marks to facilitate corrections after the speech input.
