Publication number: 20240094745Abstract: A control method includes the following. First information indicating a group control level is determined based on operation skills of operators who each perform remote monitoring or remote operation on a moving body. Second information indicating an attribute-dependent control level is determined based on attribute information on the operators. Third information indicating individual control levels of the operators is determined based on the first and second information. Moving bodies present within a predetermined range from a predetermined notification device are identified. Fourth information indicating a device control level is determined based on the third information determined for operators of the moving bodies identified. A detail of notification to be output from the predetermined notification device is determined based on the fourth information. A control command for notifying of the detail is output.Type: ApplicationFiled: November 28, 2023Publication date: March 21, 2024Inventors: Yoshihiko KAMIYA, Motoshi ANABUKI, Yuki MATSUMURA

Patent number: 4069155Abstract: A hemodialysis system for use with any type of dialyzer, such as coil-type, Kiil-type and capillary-type or hollow fiber-type dialyzers, which has a fluid circulation circuit and a bypass circuit short-circuiting the fluid circulation circuit. At one junction between the fluid circulation circuit and the bypass circuit, an ejector is employed. The ejector has a nozzle, a diffuser axially aligned with the nozzle and defining an orifice and a suction chamber communicated with the orifice. During circulation of the dialysate in the circulation circuit and from the nozzle onto the diffuser of the ejector, a negative gauge pressure is developed in the suction chamber so that the dialysate can be drawn through the bypass circuit. The circulation circuit and the bypass circuit have respective coupling assemblies for removable connection with the coil-type dialyzer and with the Kiil-type or capillary-type, or hollow fiber-type, dialyzer.Type: GrantFiled: June 1, 1976Date of Patent: January 17, 1978Assignee: Takeda Chemical Industries, Ltd.Inventors: Yasuhiro Tsujimoto, Junichi Azuma, Yoshihiko Matsumura, Katsumi Noda

Patent number: 4034126Abstract: A process for coating granular materials particularly applicable in coating granular materials each having a particle size within the range of 100 to 1,000 microns, wherein supply of a coating or binding liquid is effected in response to a specific measured electro-resistance of a fluidized means of the granular materials while supply of a coating powder is continuously effected in a predetermined variable rate. To this end, at least one electrode cooperates with a portion of the wall forming a coating apparatus to detect the specific electro-resistance which is in turn compared with a predetermined value in a comparison circuit.Type: GrantFiled: October 10, 1975Date of Patent: July 5, 1977Assignee: Takeda Chemical Industries, Ltd.Inventors: Yoshiro Funakoshi, Yoshihiko Matsumura, Masaki Yamamoto, Hiromu Komeda
