IPC: H04N7/15
Filed: 1995-02-02
Abstract: PURPOSE: To prevent confusion of communication among multi-points after mis-interruption advance by receiving a line interrupt signal and a retire command signal and conducting line interrupt processing when a system control means commands line interruption. CONSTITUTION: A hook switch 5a of a hand set 5 is closed and its ON signal is given to a system control section 10 as a line interrupt signal via a voice input output interface section 7. When a busy line among multi-point is interrupted by a multi-point communication terminal equipment, the handset 5 is placed on a cradle or a line interrupt switch of an operation section 9 is closed to enter the line interrupt signal to a control section 10. Furthermore, a line interrupt control section 10a in the control section 10 monitors whether or not the line interruption is available. Upon the receipt of the line interrupt signal by the control section 10, when the control section 10a is interrupted, the control section 10a commands interruption to a line interface section 12.  When the interruption is disable, the control section 10a invalidates the entry of the line interrupt input operation.

Title: Optical recording medium
Inventor: KOGURE SHIGERU
IPC: G11B11/10
Filed: 1991-03-05
Abstract: PURPOSE:A variable track pitch system as a technique for increasing the density of a sample system optical dish has the drawback that the data of adjacent tracks is affected if a specific track is rewritten many times and the purpose of this invention is td provide the variable track pitch system optical disk having high rewriting reliability. CONSTITUTION:The positions of individual bits for rewriting the data are determined and, therefore, projecting parts or recessed parts are previously provided in these positions on the surface of the optical disk. A recording film, protective film, reflection film, etc., are formed thereon. The inflow of heat to the adjacent tracks is prevented by the heat insulating effect of the level difference of the projecting parts or the recessed parts when the projecting parts or the recessed parts are heated. Consequently, the specific tracks can be rewritten many times without affecting the adjacent tracks.

Abstract: PURPOSE:To reduce the correction error of the title navigator regardless of the intersecting angles of intersecting roads by correcting the present position of a vehicle to a road of map data with the minimum error when the azimuth of a running road changes and a straight section continues for a prescribed distance. CONSTITUTION:A direction sensor 1 and distance sensor 2 respectively detect the advancing direction and moving distance of a vehicle and send detected values to a controller 4.

Title: Water stagnant place detecting method for synthetic resin conduit
Inventor: NAKAMARU TETSUYA
IPC: G01V3/12
Filed: 1994-03-09
Abstract: PURPOSE:To easily detect a water stagnant place in a synthetic resin conduit without requiring labor or cost. CONSTITUTION:From aboveground; an electromagnetic wave 5 is radiated to a synthetic resin conduit 2 buried in the soil 1. When stagnant water exists in the conduit 2, intensity of a reflected wave 6 of the radiated electromagnetic wave 5 is heightened, and an image displayed on a display means 12 becomes dark. On the other hand, when the stagnant water does not exists in the conduit 2, the intensity of the reflected wave 6 is reduced, and the display image becomes light. Thereby, when the intensity of the reflected wave 6 is not less than predetermined reference intensity, it is detected as a water stagnant place in the conduit 2.

Abstract: PURPOSE:To perform the conversion of a character string at high speed by setting the character string as the one unselectable a homonym in input character strings such as a KATAKANA (square form of Japanese syllabary), an alphabetical character, a numerical character, etc., other than a HIRAGANA (cursive form of Japanese syllabary). CONSTITUTION:A character string input part 11, a KANA (Japanese syllabary)/ KANJI (Chinese character) conversion part 12, a dictionary table 13, a homonym selection part 14, an input character string kind discrimination part 15, and a display part 16 are provided. It is decided whether or not the character string inputted at every KANA/KANJI conversion unit is the HIRAGANA character string, and when it is decided as the KATAKANA, the alphabetical character, or the numerical character, etc., that is not the HIRAGANA character string, no homoniym selection processing at every KANA/KANJI conversion unit is performed. Thereby, since no substitution of the input character string self- evident for the absence of the homonym other than the HIRAGANA character string for the character string selectable the homonym is performed, a desired character string in which the KANA and the KANJI are mixed is efficiently obtained.
