Patent JP-S6416110-A (JP)
Title: Digital circuit
Inventor: NEGISHI SHINJI
IPC: H03F3/42
Filed: 1987-07-10
Abstract: PURPOSE:To always properly suppress a bad influence of the mirror current by connecting the base of a bipolar transistor TR, which absorbs the mirror current, to the driving input side of a high level-side bipolar TR of an output state and connecting its base and collector to the base of a low level-side bipolar TR. CONSTITUTION:A bipolar TR Q4 which absorbs the mirror current is turned on and started by a base current Ibt temporarily supplied through a capacity element Ct from the base side of a high level-side bipolar TR Q1 of the output stage at the time of switching of the output from the low level to the high level. At this time, a mirror current IM is by-passed and absorbed by conduction of the TR Q4. As the result, the timing when the low level-side TR Q1 of the output stage is turned off is quickened at the time of switching of the output from the low level to the high level to prevent a large through current from flowing between TRs Q1 and Q2. Thus, a bad influence of the mirror current is suppressed.

Title: Document preparing device
Inventor: YAMAMOTO HIDEKI
IPC: G06F17/21
Filed: 1986-07-22
Abstract: PURPOSE:To synthesize documents even in document files different in a document format by invalidating the row modification information of a document to be synthesized and setting the format to the format set value of a generated document if the number of characters on one row in one document does not coincide with that in the other. CONSTITUTION:The document name of the document to be synthesized is selected and instructed by a keyboard input device 11. When the document is selected, a document synthesizing processor 18 reads out the number of characters on one row of the document to be synthesized from a floppy disk through a floppy disk device 16 and compares this number of characters on one row with that of the generated document. If they do not coincide with each other as the result, the row modification information of the document to be synthesized is invalidated and the format of the document to be synthesized is set to the format set value of the generated document. Thus, it is unnecessary to preliminarily allow the document formats to coincide with each other even if the document files different in the document format are synthesized, and documents are easily synthesized.

Title: Paper feeder
Inventor: KIMIZUKA JUNICHI
IPC: B65H3/06
Filed: 1987-07-10
Abstract: PURPOSE:To enable accurate control of stopping position of a semi-circular paper feed roller by operating a means for absorbing counter-electromotive force of a paper feed motor upon detection of the stopping position of the semi-circular paper feed roller through a detecting means. CONSTITUTION:When an optical path of a roller position sensor 19 for detecting the stopping position of a paper feed roller comprising a photo interruptor is blocked by a barrier board fixed to the shaft of the paper feed roller, a paper feed motor 2 is stopped so as to stop the paper feed roller. Upon stoppage of the paper feed roller 2, a transistor 37 is turned ON to turn OFF a motor drive transistor 43, while a transistor 36 is turned ON to turn ON a counter- electromotive force absorbing transistor 44 so as to absorb the counter- electromotive force of the motor 2 thus applying brake onto the motor 2. Consequently, a semi-circular paper feed roller can be stopped accurately at a stopping position in a short time through a simple structure.

Title: Mode detecting mechanism of vtr
Inventor: ISHIKAWA NOBUO
IPC: G11B15/06
Filed: 1984-08-20
Abstract: PURPOSE:To obtain a VTR with high long-term reliability, low power consumption and good workability by arranging a magnetic sensor and a permanent magnet fitted to a loading ring so as to be coincident within a plane when the ring is turned up to the play/stop state and arranging the ring and the sensor so as not to be contacted together. CONSTITUTION:The loading ring 1 is driven at the outside of a roller by a motor in the direction of arrow 10 and when a magnet 3 fitted to the ring 1 passes through while being overlapped with a Hall element 2 in a plane, a pulse signal is generated to the element 2. The turning angle of the ring 1, that is, the VTR mode is detected by this signal. Since the mode detection evice does not contact the loading ring 1, wear of contacts and fatigue/deformation of a spring do not occur and the long-term reliability is excellent. Since it is not required to thicken the ring 1 to prevent the interference with other rollers and levers, thin profile and miniaturization of the VTR are attained. Further, the workability at after service and assembling is excellent.

Title: Power supply device using fuel cell
Inventor: TAKABAYASHI YASUHIRO
IPC: H01M8/04
Filed: 1985-08-06
Abstract: PURPOSE:To make the secondary cell be of small capacity to be miniaturized, by outputting as assigned amount of electric power forcibly from a fuel cell through the controlling part when load current becomes overcurrent in excess of rated current. CONSTITUTION:When the value of detection signal 8a in a load current-detecting part 8, in which load current I1 flowing on a load 5 is detected, becomes in excess of assigned voltage, a signal 13a with the value proportional to the excessive value is added to a set-up signal 9a, and the united voltage is outputted as a set-up voltage Vs from an adder 14. A deviation amplifier 15 outputs a deviated signal 4 dependent on the difference between an output voltage signal 7a and the set-up voltage Vs, and fuel cell current If is regulated in a d-c converter so that the deviated signal 4 becomes zero. Hence, with one part of overload shared in the fuel cell 1, the secondary cell 2 of small capacity is obtained in small size.
