  • Publication number: 20220255443
    Abstract: According to an embodiment, a power conversion apparatus includes a transformer, an inverter, a rectifier, a first voltage detector, a second voltage detector, and a control unit. The inverter includes a switch and outputs AC voltage to the primary side of the transformer by an ON/OFF operation of the switch. The rectifier converts the AC voltage from the secondary side of the transformer into DC output voltage. The first voltage detector detects input voltage input to the inverter. The second voltage detector detects the output voltage. The control unit sets, on the basis of the input voltage and the output voltage, permissible ON time for which the switch is set to an ON state such that a value of current output from the inverter does not exceed an upper limit value.

  • Publication number: 20220135367
    Abstract: Proposed is an elevator control device in which an unbalance torque estimation unit configured to estimate an unbalance torque in a motor is implemented in accordance with such a new finding that the unbalance torque can be estimated based on a first time period from an output change of a brake state command signal for switching an operation state of a brake from a braking state to a releasing state to a time when the motor starts a rotating operation along with release of the brake, and on a positive or negative sign of a velocity signal obtained when the motor starts rotation. As a result, as compared to the related art, a smaller calculation load can be achieved. Further, the elevator control device can have a sufficient responsiveness for suppressing an influence of the unbalance torque.

  • Publication number: 20210001523
    Abstract: An injection moulding machine makes a long fiber length of reinforcing fibers contained in a resin moulded article to produce a high strength, rigidity, and wear and fatigue resistant resin moulded article. In a screw fiber kneading stage in an injection moulding machine, a longitudinal cross-sectional area between first flights feeding a base resin and reinforcing fibers in a feeding direction in conjunction with rotation of the screw while suppressing passage of the base resin and the reinforcing fibers is made greater at an upstream side than a downstream side in the feeding direction. In an article production method, an elongated roving containing the reinforcing fibers is continuously supplied as it is in the elongated state to the base resin plasticized inside the cylinder of the injection moulding machine to prepare a fiber-reinforced resin and the prepared fiber-reinforced resin is made to fill a mould internal space of a mould.

  • Publication number: 20200101649
    Abstract: A device for assisting molding condition determination is used with a molding method that molds an article by feeding molten material into a mold. The device includes a learning model generating unit, an input unit, and an output unit. The learning model generating unit creates a learning model through machine learning in which a plurality of molding condition element items used to mold the article and a plurality of quality element items of the molded article are used as learning data. The learning model relates to a degree of influence of each molding condition element item on each quality element item. The input unit receives input of a subject quality element item to be checked, selected from the quality element items. The output unit outputs, using the learning model, the multiple molding condition element item that has the degree of influence on the subject quality element item.

  • Patent number: 9601246
    Abstract: A hard magnetic material formed of material powders made of a R—Fe—N compound containing a light rare earth element as R, or material powders made of a Fe—N compound is used as material powders. There is formed a compact in which a density of the hard magnetic material powders differs between an outer face side portion and an inside portion of the compact such that a rate of progress of powder bonding due to microwave heating is higher in the inside portion of the compact than in the outer face side portion of the compact when an outer face of the compact is irradiated with microwaves. Then, the outer face of the compact is irradiated with the microwaves to cause the microwave heating, thereby bonding the hard magnetic material powders by oxide films which are formed on the hard magnetic material powders.

  • Publication number: 20140374643
    Abstract: There is provided a magnet manufacturing method with which a high residual magnetic flux density is obtained without using dysprosium (Dy) and without using a bonding agent. Magnetic powders made of a hard magnetic material formed of a R—Fe—N compound containing a rare earth element as R or formed of a Fe—N compound are used. In a pressurizing step, the magnetic powders are pressurized by molds multiple times to form a primary compact. In a baking step, a secondary compact is formed by heating the primary compact in an oxidizing atmosphere at a temperature lower than a decomposition temperature of the magnetic powders to bond together the outer surfaces of the adjacent magnetic powders with oxide films formed on the outer surfaces of the magnetic powders.

  • Patent number: 8065541
    Abstract: A power consumption controller controls the power consumption of a physical server having a virtual server. A management server determines an unused CPU budget from the difference between the total amount of the loads of respective virtual servers and a hypervisor and the total CPU budget of the physical server. The management server determines the drive frequency of the CPU inside the physical server based on the unused CPU budget. The management server changes a CPU allocation budget related to the respective virtual servers and the hypervisor in accordance with the determined drive frequency. The hypervisor controls the CPU allocation budget and drive frequency in accordance with an indication from the management server. Accordingly, the power consumption of the physical server is controlled.
