  • Publication number: 20240375060
    Abstract: Conventional porous membranes have a mesh structure having a relatively large pore diameter in order to improve the removability of a relatively large component such as a virus. When a contaminative liquid to be filtered is filtered, contaminants are easily accumulated in the porous membranes, clogging or the like occurs in the porous membranes, and contamination of the porous membranes easily occurs. Accordingly, an object is to provide a porous membrane having high contamination resistance and high-precision removability. To achieve the object, provided is a porous membrane including, in at least one surface, a surface portion spanning 10 ?m in thickness from the surface, being denser than an inner portion, and having a removal rate T of dextran having a weight-average molecular weight of 40,000 Da of 60 to 95%, in which a number of surface pores per unit area observed on the surface of the surface portion is 200 pores/?m2 to 2,000 pores/?m2.

  • Publication number: 20240333446
    Abstract: A base station selects, from among a plurality of code sequences orthogonal to one another, one code sequence by which an uplink signal including a demodulation reference signal repeated in a plurality of subframes is multiplied and transmits, to a terminal for which transmission of the repeated uplink signal is configured, information indicating the selected code sequence by using a field for indicating a cyclic shift and an orthogonal sequence used for the demodulation reference signal. A terminal receives information indicating one of a plurality of code sequences orthogonal to one another using a field for indicating a cyclic shift and an orthogonal sequence used for a demodulation reference signal and multiplies an uplink signal including the demodulation reference signal repeated in a plurality of subframes by the code sequence indicated by the information.

  • Patent number: 12105902
    Abstract: A method to be performed by a sensor controller that periodically transmits an uplink signal, and by a stylus that, upon receiving the uplink signal, determines a transmission and reception schedule for a downlink signal and the uplink signal on the basis of the reception timing of the uplink signal. The method includes executing, by the stylus, an uplink signal receiving operation for a first predetermined period of time according to the transmission and reception schedule. The method includes, responsive to the uplink signal not received through the receiving operation and expiration of the first predetermined period of time, continuing, by the stylus, the uplink signal receiving operation for a second predetermined period of time, instead of transmitting the downlink signal according to the transmission and reception schedule.

  • Patent number: 11767851
    Abstract: A magnetic bearing control apparatus and a vacuum pump which do not require a displacement sensor, which enable control with high accuracy, and which are small and low cost. A rate of change (di/dt) that is a time derivative of a current value Im flowing through an electromagnet varies in accordance with a magnitude of a displacement of a gap between a target member and the electromagnet. The rate of change (di/dt) can be obtained by detecting a voltage value Vs that is generated at both ends of an inductive element. Therefore, by detecting the voltage value Vs, the magnitude of the displacement of the gap can be estimated by calculation. Inductive elements are connected in series to electromagnets and the voltage Vs between the inductive elements is detected by the differential input amplifier. A single period of switching of a PWM switching amplifier is constituted by a current control period of the electromagnet and a displacement detection period for detecting the rate of change (di/dt).

  • Patent number: 11654828
    Abstract: From each of in-vehicle units in vehicles, a travel behavior data indicating a travel behavior of the vehicle is received and recorded in a travel history database. The travel behavior data of the vehicles are read from the travel history database; an avoidance action arising in each of the vehicles is detected based on the read travel behavior data. From the detected avoidance actions of the vehicles, a related avoidance action group being avoidance actions arising due to an identical object at different positions at different points of times in different target vehicles is extracted based on an occurrence position and an occurrence point of time of each detected avoidance action. Information on position change of the identical object as a cause of the extracted related avoidance action group is recorded as an alert target data.
