Title: Deflection coil
Inventor: KUWABARA YASUNAGA
IPC: H01J29/76
Filed: 1989-02-15
Abstract: PURPOSE:To freely control a deflecting magnetic field generated by a deflection coil by adjusting an impedance of a changeable inductance coil which will not generate a deflection magnetic field connected parallel with one zone of the deflection coil. CONSTITUTION:One zone of winding forming a deflection coil 1 is connected parallel with a changeable inductance coil 6 which will not generate a deflecting magnetic field directly.

Title: Driving method for pulse motor
Inventor: HANAKATA TAKAMASA
IPC: H02P8/22
Filed: 1982-03-05
Abstract: PURPOSE:To reduce power sonsumption, and to cheapen the manufacturing cost by selecting and controlling exciting methods in response to the frequency of input pulse signals applied to each phase of a pulse motor. CONSTITUTION:A CPU 14 outputs driving-system informations to the pulse motor 8 through a driver 16 while bringing frequency to 1500PPS by two-phase excitation in a carriage return instruction 19 and frequency to 500PPS by one- phase excitation in a printing instruction 18. According to said driving method for the pulse motor, since one-phase excitation is executed during printing revolving torque is weak though time per one step is long, thus resulting in no vibration. Since two-phase excitation is executed during the return of a carriage, revolving torque is strong though time per one step is short, thus resulting in the state of smooth drive through which vibration is not generated. Power consumed in the pulse motor and a printing head is reduced.

Title: Voltage/frequency converter
Inventor: NUKUI TADASHI
IPC: H03K7/06
Filed: 1994-03-04
Abstract: PURPOSE:To reduce a linearity error even when an operational amplifier of an integration device receives an input offset voltage by obtaining an average frequency from frequencies obtained based on an input voltage and an inverted input voltage. CONSTITUTION:A charge by a synthesis current I3 resulting from an input voltage E and a negative reference voltage VSS is discharged by integrating the input voltages E (positive integration period) and a charge by a synthesis current I3 resulting from an inverted input voltage EN and a positive reference voltage VDD is discharged by integrating the input voltages EN (negative integration period) and then a prescribed number of the positive integration periods and the negative integration periods is repeated complementarily. In this case, since the time required for charging/discharging is respectively proportional to the input voltage and the inverted input voltage, an output period of a selection signal K obtained by the repetition of the operation is proportional to the input voltage. Thus, the input voltage and the inverted input voltage are converted into corresponding frequencies.

Title: Heat pump hot water feed heating cooling device
Inventor: KURAMOTO SHINJI
IPC: F25B29/00
Filed: 1988-02-19
Abstract: PURPOSE:To enable execution of stable operation even when a heat load is low and to produce high temperature hot water even during the wintertime, by a method wherein, when a delivery pressure or a delivery gas temperature from a compressor is increased to a value outside an allowable range, heat exchange is effected by means of a refrigerant and storage hot water. CONSTITUTION:When an indoor load is low even if a compressor 4 is run at a minimum capacity, a delivery pressure or a delivery gas temperature is detected by a delivery pressure sensor 12 or a delivery gas thermostat 11. A heating load is apparently increased through the flow of hot water in a hot water storage tank 13 to a heat exchanger 3 between a refrigerant and water, and a load is controlled to a proper value through drive of a capacity varying type circulating pump 14. As a result, even when a heating operation load is low, a stable operation can be performed. Since hot water heat-exchanged by the heat exchanger 3 between a refrigerant and water is stored at a high temperature in the hot water storage tank 13, a hot water temperature can be obtained sufficiently even during the wintertime.
