  • Patent number: 9382094
    Abstract: An elevator renovation method, which is capable of reducing a renovation period and enabling effective use of a space when an existing hydraulic elevator is renovated to a non-hydraulic elevator. The elevator renovation method involves renovating a hydraulic elevator in which a plunger provided integrally with a car is hydraulically driven to a non-hydraulic elevator. The elevator renovation method includes; providing a driving device for generating a driving force for raising the car; leaving the plunger so that the plunger can be raised and lowered inside an existing jack; and obtaining the non-hydraulic elevator by exerting the driving force of the driving device in a direction in which the plunger is moved up to raise the car.

  • Patent number: 9207607
    Abstract: An image forming apparatus that heat-fixes a toner image onto a recording sheet passing through a fixing nip formed by pressing a pressurizing member against a heating rotational body heated by a heater, comprising: a storage unit storing a basic power consumption level of the heater determined in advance in a situation where inflow of inrush current to the heater is not occurring; an estimation unit calculating an estimated power consumption level of the heater by estimating an increase in the power consumption level, with respect to the basic power consumption level, brought about by inflow of inrush current to the heater; and an output unit outputting the estimated power consumption level. The heater switches between a heating state of receiving power supply and a non-heating state of not receiving power supply.

    Abstract: An electric power supply control device comprises AC/DC converter, DC/DC converters, and an output electrical voltage monitor unit of the AC/DC converter. When output electrical voltage of the AC/DC converter increases to the first preset value P1, the AC/DC converter stops the convert. When the output electrical voltage decreases to the second preset value P2, the AC/DC converter restarts the convert. The first preset value P1 is equal to or less than the lowest value, out of the upper limit values in electrical voltage ranges in which the DC/DC converters CV1 and CV2 can work. The second preset value P2 is more than or equal to the highest value, out of the lower limit values in electrical voltage ranges in which the DC/DC converters CV1 and CV2 can work.
