Title: Switch circuit
Inventor: TOKUNAGA KIICHI
IPC: H03K17/73
Filed: 1984-02-17
Abstract: PURPOSE:To attain stable operation with low loss over a wide current region by providing a capacitor circuit playing a role of absorption of circuit energy at OFF state and of operation of drive energy supply at ON state to MOSFETs operated sequentially in series connection. CONSTITUTION:When a positive gate signal is applied to an MOSFET11, the 11 starts conduction, a capacitor 31 starts discharge and an MOSFET12 starts conduction. The MOSFETs 13-1n start conduction sequentially in the same way as the 12 and the switch circuit is turned on. The MOSFET11 keeps the ON state during the ON period even with a small voltage drop. This is the same as the 12 and preceding MOSFETs. Thus, even if lots of MOSFETs are connected in series, the voltage drop of the switch circuit at ON state is decreased sufficiently. When the application of a gate signal to the MOSFET11 is stopped, the MOSFET11 is interrupted and the drain current reaches 0. Thus, the current of the load circuit flows via the MOSFET12, a diode 61 and a capacitor 31, the current of the MOSFET12 is drawn at ON state and the MOSFET12 is cut off. The same way is applicable to the MOSFET13 and preceding FETs, and the circuit is turned off.

Abstract: PURPOSE:To obtain the material of fin made of aluminum, which is provided with excellent hydrophilic property, anticorrosion property, resistance to degreasing and molding property while showing little abrasion of a mold or cracking upon molding, by a method wherein a hydrophilic organic film of polyacrylic ester series or polymethacrylic ester series is formed on the surface of the fin made of aluminum or aluminum alloy. CONSTITUTION:The organic molecular resin of polyacrylic ester series or polymethacrylic ester series is employed and it is not questioned whether it belongs to an independent polymer or copolymer. The thickness of the film consisting of the organic high molecular resin is preferable to be 0.5-10mum. In case the thickness of the film is thinner than 0.5mum, there is a question in anticorrosion property but when it is thicker than 10mum, the thermal conductivity of the fin is precluded and the molding property becomes worse. The material of fin made of aluminum is consisting of an aluminum sheet and the film of organic high molecular resin prominent in anticorrosion property, resistance to degreasing, molding property or the like and formed on the surface of the aluminum sheet, therefore, the ductility thereof is good, a crack will never be generated upon forming the fin and the abrasion of a mold at molding may be very little.

Title: Delay circuit of electronic switch
Inventor: FUKUYAMA TOSHIBUMI
IPC: H03K17/94
Filed: 1984-02-15
Abstract: PURPOSE:To prevent malfunction when a pulse with a short period is inputted by detecting it by the 2nd comparator that a voltage changed with the discharge of a charge/discharge circuit discharged after an output of the 1st comparator is opened exceeds a prescribed level. CONSTITUTION:A square wave signal is fed to one input of an exclusive OR circuit G1 from an output terminal of a detection circuit 12. Since a transistor (Tr) 1 to which a signal at a point (e) is fed back is turned off, when the level of a point (a) is at ''H'' level, the level of a point (c) is dropped to ''L''. The output of a comparator CM1 is opened, an electric charge charged in a capacitor C11 is discharged and the potential at an output terminal of the comparator CM1 is increased. When the potential at a point (d) is increased, a potential at an output terminal of a comparator CM2 reaches ''H''. An ''L'' signal is led out to the output terminal of an exclusive OR circuit G3 and the ''H'' output of the comparator CM2 is led as it is to the output terminal of the exclusive OR circuit G2. The Tr2 is turned on, a relay Ry is activated and the level of a point (f) reaches ''L''.

IPC: B65H51/32
Filed: 1991-01-29
Abstract: PURPOSE:To prevent the end edge of a cut linear material from coming into contact with the surface of a winding bobbin on fully wound side and its external surface from being damaged, when the winding bobbin on the fully wound side changed over to a winding bobbin on an empty side, in the continuous winder of a linear material such as optical fiber. CONSTITUTION:Winding rollers 6, 7 and suction nozzles 8a, 8b are disposed in the middle between winding bobbins 2a and 2b. At the time of changeover, while the winding rollers 6, 7 are coming into contact with each other to hold a linear material 1 between them for winding, rotation of the winding bobbin 2b on a fully wound side stops, and the linear material 1 wound by the winding rollers is processed by sucking with the suction nozzle 8b, so it is possible to change over the winding bobbin 2b on a fully wound side to an empty winding bobbin 2a.

Title: Character string processing unit
Inventor: YAMAMURA TAKASHI
IPC: G06F17/22
Filed: 1984-02-18
Abstract: PURPOSE:To simplify the operation even when no error exists by urging the operator to discriminate the propriety of the conversion and input a command before a converted character string is confirmed so as to progress smoothly an error correcting procedure. CONSTITUTION:When a converted character string ''It was rain yesterday, and it will be ...tomorrow'' is converted to the part and displayed on a conversion character display area 44, a Kana (Japanese syllabary) string ''fine'' is inputted from a read character key 12. A straight write converting section 24 converts the Kana string ''fine'' into a Kanji (Chinese character)/ Kana mixed character string ''fine'', transfers the result to a storage section 28 and a converted character string ''weather'' is introduced from the input character string ''weather''. Then the converting character storage section 28 detects that a character is stored in a storage area corresponding to a hot zone 48 of the converted character storage area and gives a command of generation of a warning tone to a warning generating section 32. The operator operates a confirmation key 14 when the converted character string displayed to a converted character string display area 44 is coincident with the string intended for the operator. When the converted character string displayed the converted character string display area 44 differs what the operator intends for, the operator does not operate the confirmation key 14 and corrects it by operating the function key 16 and the read character key 12.

IPC: H03K17/00
Filed: 1993-02-18
Abstract: PURPOSE:To obtain a multiplexer circuit with a synchronizing function whose constitution is relatively simple with the highest operating speed. CONSTITUTION:A phase comparator circuit 2 detects the phase mismatching of a timing signal for fetching a low speed digital input data signal generated by an N frequency-divider circuit 4 with an input timing signal indicating the phase of the input data signal. A control circuit 3 temporarily stops the operation of the N frequency-divider circuit 4 each time the phase mismatching is detected. Thus, the operating phase of the N frequency-divider circuit 4 can be automatically adjusted by repeating the temporary stop, and the phase of the timing signal generated by the N frequency-divider circuit 4 can be adjusted to the phase optimal to the fetch of the input data signal.
