Title: Mis-jetting detector for ink jet printer
Inventor: FUKANO TAKAKAZU
IPC: B41J2/01
Filed: 1987-05-12
Abstract: PURPOSE:To securely detect a mis-jetting of a jot, by jetting an ink droplet toward a vibrating plate disposed opposite to a jet nozzle, and detecting a mis-jetting on the basis of the presence or absence of vibration. CONSTITUTION:When a printing signal at an H level is inputted to a driving circuit 63, a piezoelectric element 1 is driven to push a pressure chamber 8, whereby an ink droplet 2 is jetted from a jet nozzle 9 to collide against a vibrating plate 3, thereby generating an electrical signal. The signal is amplified to be a signal C through an amplifying circuit 64 comprising operational amplifiers 38-40, resistors 23-28, 30, 31 and capacitors 22, 29, and the signal C is inputted to a comparing circuit 65. When the ink droplet 2 is normally jetted, a detection signal (d) is at an L level. In the cases of jetting the ink droplet 2 in an erroneous direction, incapability of jetting the ink droplet 2 or when the ink droplet 2 is insufficient in size, vibration which enables detection of an electrical signal is not generated in the plate 3, and a detection signal (d) at an H level is outputted. Thus, mis-jetting of a dot can be detected, for any recording head with any dot pitch, dot diameter or nozzle number.

Abstract: PURPOSE:To attain a word processor which has the excellent operability and the reduced candidate correcting frequency by providing a means which converts automatically a word modified by a word changed by a KANA (Japanese syllabary)/KANJI (Chinese character) conversion means into a correct word according to the changed word. CONSTITUTION:Some words contained in a character string converted by a KANA/KANJI converter 3 are changed into other homonyms with retrieval of a KANA/KANJI conversion dictionary 4. Thus a meaning sorting dictionary 5 which stores the meaning sorts obtained by sorting the meaning categories of the substantives by the words modified by the changed words is retrieved together with a case frame dictionary 6 which stores the meaning sorts obtained by sorting the meaning categories of the substantives controlled by the declina ble words as well as the descriptions, the parts of speech, and the case informa tion of the declinable words. Then the words are automatically converted into the correct Japanese words in accordance with the changed words. As a result, the correcting operations of a homonym part can be decreased together with the excellent operability for a word processor which contains a KANA/KANJI conversion means.

Title: Pressure-tight tube element for submarine optical fiber cable
Inventor: HYODO KENJI
IPC: G02B6/44
Filed: 1985-05-29
Abstract: PURPOSE:To considerably improve corrosion resistance by coating the surface of a metallic wire or metallic plate as a pressure-tight tube element with a copper or copper alloy plating layer of 0.5-15mum thickness. CONSTITUTION:The metallic wire or metallic plate 7 as a core is coated with the copper or copper alloy plating layer to form the pressure-tight tube element for a submarine optical fiber cable. The metallic wire or metallic plate 7 operates as the reinforcing material of the optical fiber cable and is formed by coating an Al material with the copper or copper alloy plating layer 8 so as to prevent hydrogen gas from being produced by the corrosion reaction of metal when sea water enters the submarine optical fiber cable. This plating layer 8 is formed to a thickness of 0.5-15mum; when the thickness is >=0.5mum, prevention effect is small and when >15mum, the cost becomes high.
