Title: Coil drive circuit
Inventor: FURUYA MISAO
IPC: H04N3/23
Filed: 1990-11-26
Abstract: PURPOSE:To correct the linearity of a deflection current over a wide range by means of a circuit able to be circuit integration by connecting a negative resistance circuit in series with a coil and setting a negative resistance to be almost cancelled with the resistance of the coil. CONSTITUTION:A negative resistance circuit 1 consists of two operational amplifiers 2, 3 connecting a positive power supply and five resistors R1-R5 is connected in series with a coil 6 and a negative resistance of the negative resistance circuit 1 is set to be a value almost cancelled by a resistance RH of the coil 6. Since the resistive component of the coil is cancelled, the deflection current is not saturated but linear. Thus, the correction range of the linearity is wide and the adjustment for each receiver is not required and the coil drive circuit is realized, in which the productivity is high, the circuit integration is attained and which is advantageous for miniaturization of the receiver with simple configuration.

Title: Power converter with overvoltage-preventing device
Inventor: KUBOTA YUZURU
IPC: H02M7/483
Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To prevent the overvoltage of a multiplex power converter and at the same time reduce the voltage load to a specific switching element by independently determining the operation/non-operation of a chopper circuit that is provided for each capacitor so that a DC voltage for each capacitor of a power converter can be set within a predetermined range. SOLUTION: When a DC differential voltage is generated between DC smoothing capacitors 5 and 7 when a system fails, an upper chopper circuit 6 and a lower chopper circuit 8 are operated and the energy of the DC smoothing capacitors 5 and 7 is discharged if a first predetermined voltage is exceeded, based on the DC voltage detection signal of the DC smoothing capacitors 5 and 7 by an upper control circuit 13 and a lower control circuit 14. When the level becomes lower than a second predetermined level, operation is stopped. As a result, by allowing each different chopper current to flow to the upper and lower chopper circuits 6 and 8, the upper and lower DC voltage is controlled a given value or less and the overvoltage of power converters 1 and 2 is prevented, thus reducing the load of voltage to a switching element.

Abstract: PURPOSE:To make positioning of a recording paper sheet secure without employing any special guide by longitudinally forming an insert port, an outlet port, and a transfer passage such that the recording paper sheets are inserted, transferred and discharged in laterally upright condition. CONSTITUTION:When a recording paper sheet 4 in upright condition is inserted into an insert port 12 at the time of printing, its bottom end edge, namely one of the edges of the width direction, comes to the bottom surface of the insert port 12 by its own weight and printing is performed thereafter while the bottom end edge slides on the bottom surfaces of a transfer passage 14 and an outlet port 13. As a matter of course, the paper sheet remains to be transferred while sliding on the bottom surface even if there is some changes in the dimension of the paper width. Also, it is not necessarily necessary to put the paper sheet in the upright condition, but it also can be put in oblique condition as long as the paper sheet is in contact with the bottom surface by the own weight of the recording paper sheet 4. As a result, positioning is always performed securely without requiring any special guide.
