Filed: 1989-03-20
Abstract: PURPOSE:To suppress the leakage of light by using InP to which a slight amt. of group III elements and/or group V elements are added as an optical wave guide layer or clad layer. CONSTITUTION:This optical wave guide is so formed that the differences in the refractive index between the optical wave guide layer 6 and clad layers 4, 8 are respectively <=3X10<-3> if the optical wave guide layer 6 is the quaternary mixed crystals formed by adding the group III elements and the group V elements to the InP or the ternary mixed crystals formed by adding the group V elements to the InP and the clad layers 4, 8 are the InP or if the optical wave guide layer 6 is the InP and the clad layers 4, 8 are the ternary mixed crystals formed by adding the group III elements to the InP. Namely, the difference in the refractive index between the optical wave guide layer 6 and the clad layers 4, 8 is decreased and boundary defects are decreased by utilizing the phenomenon that the refractive index decreases if a slight amt. of the group III elements are added to the InP and the refractive index increases slightly if a slight amt. of the group V elements are added thereto. The concn. of light is obviated and the leakage of light is decreased even if the optical wave guide layer is formed by bending the same.

SOLUTION: The character sorting including the English letter, numeric character, symbol, HIRAGANA, KATAKANA, KANJI, full size, half size, etc., of every recognized character code are displayed simultaneously with a recognized character. Then a handwriting recognition part 5232 of this terminal device recognizes the input characters based on the handwriting data, produces the character codes of recognition results and the candidate character codes in case of wrong recognition and sends them to an intermediate frame control part 5233. The part 5233 notifies a character font display part 52331 of the character codes to display the recognized character codes in an intermediate frame and also notifies a type display part of the character codes.  The type display part checks whether the corresponding character code belongs to an English alphabet, a symbol or a numeric character, etc., and shows this checked result under the intermediate frame.

Title: Passage side traffic information detector
IPC: H04H20/55
Filed: 1992-03-26
Abstract: PURPOSE:To know that passage side traffic information is on air even when an information sign is overlocked by allowing an operator to know that the information is on air when the level of the electric field of a received broadcast electric wave is more than a set value. CONSTITUTION:A passage side traffic information private tune 2 is equipped with a signal meter which outputs a direct current voltage according to the level of the received electric field of a traffic information station. Then, synchronized with a broadcast frequency preliminarily so that the voltage can be increased according to the intensity of the electric field. An electric field level comparator 3 receives the broadcast frequency, and resistances R1 and R2 are set so that a transistor Tr1 can be turned on when the level of the electric field is more than the prescribed value.

Abstract: PURPOSE:To improve the utilizing efficiency of a memory by applying coding in response to gradation number of a picture stored in a memory. CONSTITUTION:When a read mode is selected from a key entry section 1 and the start of storage is commanded, a read section 3 confirms the presence of an original to start reading and a control section 2 sends a picture data by one line in the read section 3 to a coding section 4. When the read mode is the binary picture mode, the coding section 4 codes the picture by the modified modified read(MMR) system and when the read mode is the multi-value picture mode, the section 4 codes the picture by the modified Huffman(MH) system and stores the coded data to a picture memory 5. Thus, an intermediate tone picture is coded by the MH system in this way, then the data quantity is substantially reduced and the utilizing efficiency of the picture memory 5 is improved.
