  • Publication number: 20200071675
    Abstract: The present invention relates to a method for producing endothelial cells, including carrying out: (a) inducing a population of mesoderm-lineage cells containing endothelial progenitor cells from pluripotent stem cells without forming an embryoid body; and (b) culturing the population of mesoderm-lineage cells containing endothelial progenitor cells in the presence of RepSox, in this order. According to the present invention, endothelial cells with high quality can be efficiently produced from pluripotent stem cells. The endothelial cells obtained by the method of the present invention are useful for the production of, for example, a myocardial sheet, and expected to be utilized in the treatment of a heart disease. A myocardial sheet can be produced by mixing the endothelial cells obtained by the method of the present invention with myocardial cells and mural cells and culturing the cells.

    Abstract: The present invention relates to a signal processing apparatus and a signal processing method, an encoder and an encoding method, a decoder and a decoding method, and a program capable of reproducing music signal having a better sound quality by expansion of frequency band. An encoder sets an interval including 16 frames as interval section to be processed, outputs high band encoded data for obtaining the high band component of an input signal and low band encoded data obtained by encoding the low band signal of the input signal for each section to be processed. In this case, for each frame, a coefficient used in estimation of the high band component is selected and the section to be processed is divided into continuous frame segments including continuous frames from which the coefficient with the same section to be processed is selected.

  • Publication number: 20200019358
    Abstract: An image forming apparatus includes a communication device, a received data processing portion, a human detection sensor, a sensitivity setting portion, a rest control portion, and a return control portion. The sensitivity setting portion sets, based on content of the job data, the sensitivity of the human detection sensor for a time when specific devices including the received data processing portion are in a predetermined rest state. The rest control portion causes the specific devices to transit to the rest state when a predetermined rest condition is satisfied. The return control portion causes the specific devices to transit from the rest state to a return state when the human detection sensor detects a human body in the situation where the specific devices are in the rest state, wherein larger power is consumed in the return state than in the rest state.

  • Patent number: 10536601
    Abstract: A controller of an information processing device changes a current state among standby states including a first standby state, a second standby state, and a third standby state, in which power consumption decreases in this order. When the non-operation duration runs for a first period, the controller changes the current state from the first standby state to the second standby state. When the non-operation duration subsequently runs for a second period, the controller changes the current state from the second standby state to the third standby state. When the sensor detects a detection target in the second standby state or the third standby state, the controller changes the current state to the first standby state. When the non-operation duration runs for a third period starting from state change, the controller changes the current state from the first standby state to the previous standby state.

  • Publication number: 20190324697
    Abstract: An image forming apparatus operates in a normal mode in a first electric power state and in a power saving mode in which more electric power is saved than in the first electric power state. The image forming apparatus includes a motion sensor, an operation section, and a controller. The controller executes a first timer process in response to receipt of the detection signal and executes a second timer process in response to receipt of the operation signal. At a time when a first period elapses indicating that the first timer process times out, the controller transitions from the normal mode to the power saving mode. At a time when a second period elapses indicating that the second timer process times out, the controller transitions from the normal mode to the power saving mode. The first period is shorter than the second period.
