  • Patent number: 8582326
    Abstract: A resonance-type power supply is provided in which no short circuit occurs and driving is performed with a constant switching period by performing switching control using a change of magnetic flux of a magnetic component as a trigger. When the change of magnetic flux of the transformer is detected, the first switching control signal is caused to transition to the Hi level. The detection voltage signal is A/D-converted, a first on-time is determined from the level thereof, and a second on-time is calculated by subtracting the first on-time from the constant switching period. When the first switching control signal is caused to transition to the Low level based on the first on-time, the change of magnetic flux of the transformer is detected, and the second switching control signal is caused to transition to the Hi level and is caused to transition to the Low level after the second on-time has elapsed.

    Abstract: A fitting recess portion that connects fitting holes to each other is formed in a peripheral face of a ball screw nut. A circulation member includes a pair of fitted portions that are fitted in the fitting holes, and a connecting portion that provides communication between the fitted portions. A communication groove that has an opening on the fitted end side of the connecting portion and that extends in the axial direction is formed in the connecting portion. When the connecting portion is fitted in the fitting recess portion and the opening of the communication groove formed in the connecting portion is blocked by a bottom portion of the fitting recess portion, a second path that forms a return path together with first paths formed in the fitted portions is formed.

  • Patent number: 8304158
    Abstract: A method for manufacturing a toner includes a pre-mixing step and a coating step. In the pre-mixing step, a secondary aggregate of the fine resin particles is disaggregated, while toner base particles and fine resin particles are mixed and stirred using a rotary stirring apparatus. Thus obtained disaggregated fine resin particles are fixed to the surface of the toner base particle. Thus, a fine resin particle-fixed toner is obtained. The rotary stirring apparatus includes a rotary stirring section, a temperature regulation section, a circulating section, and a spraying section. In the coating step, a liquid is sprayed to the fine resin particle-fixed toner with the spraying section using the rotary stirring apparatus. Thus, a film of the fine resin particles is formed. In the pre-mixing step and the coating step, temperature regulation is conducted in the temperature regulation section.

  • Patent number: 8276007
    Abstract: A processor includes analog signal input ports, an A/D conversion unit, and an ALU in a stage subsequent to the A/D conversion unit, separately from a CPU. The ALU not only stores a comparison result in a RAM independently of the CPU, but also compares an output value of the A/D conversion unit with a reference value set in the RAM, and interrupts the CPU or issues a command to a PWM generator in accordance with a flag based on the comparison result. This realizes high-speed processing in accordance with a change in an analog signal, although the processor has a low cost and a low clock frequency overall.
