  • Publication number: 20190292723
    Abstract: Disclosed herein is a method for producing an elastically stretchable artificial leather, which includes the steps of forming microfiberizable fibers into a web, entangling the obtained web to produce an entangled nonwoven fabric, converting the microfiberizable fibers in the nonwoven fabric to microfine fibers thereby producing a substrate for artificial leather, producing an artificial leather from the obtained substrate for artificial leather, bringing the obtained artificial leather into close contact with an elastomer sheet stretched in a machine direction by 5 to 40%, shrinking the artificial leather in the machine direction simultaneously with the elastomer sheet by relaxing elongation of the elastomer sheet to obtain an artificial leather in shrunk state, heat treating the artificial leather in shrunk state, and then peeling the heat treated artificial leather off from the elastomer sheet.

  • Patent number: 9806653
    Abstract: A control apparatus calculates a total loss change amount that is a power loss change amount of a motor control system including respective power loss change amounts of a converter, an inverter, and a motor of the motor control system. Based on the total loss change amount, during a correction-allowed period that is a period during which square wave control is performed, the control apparatus performs correction to decrease a current output voltage command value of the converter when the current output voltage command value is determined to be greater than the output voltage of the converter at which actual total power loss change amount becomes minimum. When the current output voltage command value is determined to be less than the output voltage of the converter at which actual total power loss change amount becomes minimum, the control apparatus performs correction to increase the current output voltage command value.

  • Patent number: 9166511
    Abstract: A converter controls a system voltage, which is a DC link voltage of an inverter, in accordance with a voltage command value. The inverter outputs a rectangular wave voltage having the system voltage as amplitude to an AC motor during application of rectangular wave voltage control. During application of rectangular wave voltage control, a voltage command value for the system voltage is modified such that a current phase on a d-q plane of the AC motor is brought closer to a target current phase line. The target current phase line is set on an advance side relative to an optimal current phase line which is a set of current phases at which output torque is maximized for the same amplitude of a motor current in the AC motor.

  • Patent number: 8625029
    Abstract: A circuit for detection of an HDMI source device to an HDMI sink device through an HDMI sink connector without regard for the activity state of the HDMI source device has a pull-up resistor having first and second terminals with the first terminal coupled to a DC power source. A switching device is coupled between the pull-up resistor's second terminal and ground at a circuit node. The switching device is switched on to couple the circuit node to ground when power is applied to a control terminal thereof from the HDMI sink connector power pin, and being switched off otherwise. The circuit node is coupled to a DDC/CEC GROUND pin of the HDMI sink connector. The circuit node is readable as a binary signal to indicate the presence of a source device to the HDMI sink connector, wherein the node exhibits a logic low signal when either the node is grounded by the DDC/CEC GROUND pin connection to a source device or when the switching device is switched on.

  • Patent number: 8602859
    Abstract: To reflect a player's degree of skill in a battle between a player character and an enemy character, and increase a strategic element. In the event that a player selects magic as an action of a player character in a battle between a player character and an enemy character, a puzzle battle is started. In the puzzle battle, a magic army (a block frame) is displayed on a display device in accordance with a kind of magic selected, the player moves or rotates a block falling from above the display device by operating an input device, stops it in a desired position, and fills the magic army. In the event that all squares of the magic army are filled with the blocks before a time elapsing from a start of the puzzle battle, displayed on an elapsed time gauge, reaches a prescribed time, the magic selected by the player is unleashed, and inflicts damage on the enemy character. An effectiveness of the magic depends on an overlapping, and a protrusion from the magic army, of the blocks.

  • Patent number: 8317579
    Abstract: A video game is provided in which a player can switch a player character in a battle to an enemy character by a switching operation. With such a switching operation, the player performs the battle with the enemy character. If a predetermined time elapses, the enemy character is switched back to the player character. At this time, an HP of the enemy character reflects on an HP of the player character. If a special ability of the enemy character is used, the special ability is inherited by the player character and can be used in battles thereafter.
