IPC: G11B15/02
Filed: 1984-02-29
Abstract: PURPOSE:To improve the reproducing function of a cassette tape recorder by reproducing alternately the music of different cassette tapes by means of two mechanisms which can reverse the tape drive. CONSTITUTION:A variable M is set at initial value when an alternate reproduction switch 4 is kept off. When the switch 4 is turned on a mechanism 2 is put under a reproduction mode. Then the drive of the mechanism 2 is reversed when a tape reaches its termination to maintain the reproduction mode. Then the M is changed to 1 when a music interval detecting part 21 detects a music interval. Thus the mechanism 2 is stopped and a mechanism 3 starts a reproducing action. If the tape termination is detected under such conditions, the driving direction of the mechanism 3 is reversed to keep the reproducing mode. When a music interval is detected, the M is set at 0 and the mechanism 2 starts a reproducing action. Hereafter mechanisms 2 and 3 repeat the reproducing actions alternately in the same way.

Title: Train schedule drawing up device
Inventor: KITAGAWA HIDEYUMI
IPC: B61L27/00
Filed: 1995-02-28
Abstract: PURPOSE: To draw up a finely harmonized schedule by, in the case where a selected station is a branched station, referring a planned schedule to a rear station adjacent to the branched station, and then computing an intended arrival time when a train on a different line arrives at the branched station, and when it is earlier than the intended arrival time, outputting a command indicating that another station is to be selected. CONSTITUTION: In the case where a station selected by a station selecting means 4 is a branched station, by referring a planned schedule for a rear station adjacent to the branched station existing on a line different from a line where a train referred by a time deciding means 5 runs, a planned schedule setting up section 7 computes an intended arrival time when a train running on a different line arrives at the branched station. In the case where the computed intended arrival time is earlier than the intended arrival time of the train referred by the time deciding means 5, a varying means 11 outputs a command indicating that an another station is to be selected to a station selecting means 4. Thus even in the case where the branched station exists, a schedule harmonized for the whole lines can be drawn up without giving too much importance to only a train running on one line.

Abstract: PURPOSE:To input en-size characters while fingers are placed on their home positions so that interruption of the flow of thinking can be reduced while a composition is inputted by giving a Kanji (Chinese character) converting, Katakana (square form of Japanese syllabary) converting, and en converting functions to one conversion key. CONSTITUTION:When a conversion key 11c is depressed, a converting means 13 refers to a converting character information storing area 16. Then the means 13 actuates a Kanji converting means 18 when Kanji information is stored in an inputted character storing area 15, Katakana converting means 19 when Katakana information is stored, and en converting means 20 when en information is stored. When Hiragana (round form of Japanese syllabary) information is stored in the area 15, the means 13 causes a display section to display the Hiragana stored in the area 15. Thus the information stored in the converting character information storing area 16 is rewritten by the converting means 13 in corresponding to the operation of the conversion key 11c. Therefore, Kanji, Katakana of em size, Katakana of en size, and Hiragana corresponding to the Hiragana stored in the area 15 are successively displayed on the display section without operating functions keys. Thus flow of thinking is not interrupted.
