  • Publication number: 20220051828
    Abstract: Provided is a target transport system which is advantageous in simplifying and downsizing a configuration in production of radio-isotopes using an accelerator and in which components are hardly affected to be damaged by radiation. The target transport system includes: a transport pipeline through which a target body is transported; a target holding part that holds the target body and allows the target body to be irradiated with particle beams; and a pump, the transport pipeline, and a target entry port that transport the target body to the target holding part by a cooling water. The pump, the transport pipeline, and the target entry port cause the cooling water to flow in the transport direction, and the target body is recovered from the transport pipeline by the cooling water.

  • Patent number: 11125325
    Abstract: A shift range switching system includes: a motor that includes a motor winding and generates a cogging torque by a permanent magnet; a drive circuit; an output shaft; a shift range switching mechanism that includes a trough providing member with troughs and crests and integrally rotates with the output shaft, an engagement member that fits in one trough corresponding to a shift range, and an urging member that urges the engagement member toward the one trough; and a control unit. The engagement member drops into the one trough with an allowance. When an abnormality occurs in a motor drive system in an ascending action in which the engagement member moves from one trough toward one crest, the shift range switching system reduces an occurrence probability of an intermediate range stop abnormality.
