摘要:
A drive unit of a magnet coupling pump, in which leakage of the magnetic flux to the outside and the effect of the external magnetic field are suppressed. The drive unit includes: a driving magnet (219) positioned at an outside of the driven magnet (19) of the magnetic coupling pump (100) with respect to a rotation axis (A) of the magnetic coupling pump (100) to face the driven magnet (19) with a gap; a cup tube portion (221) made of a ferromagnetic material and in a tubular shape centered on the rotation axis (A); a case main body (231) including a cup (220) in which the driving magnet is fixed inside of the cup tube portion; a motor (210) rotating the cup around the rotation axis, and a tube portion (232), which is tubular in shape. The cup is provided in the tube portion (232) with a gap.

An artificial cardiac pump includes an impeller (3) rotatably supported on a fixed shaft body (2) in a housing (1) and a drive mechanism rotating the impeller, wherein blood is taken in from the front side and force-fed to the rear side by the rotation of the impeller (3). The shaft body (2) is connected between a front side fixed body (5) fixed to a straightening plate (4) joined to the housing (1) at the front of the impeller (3) and a rear side fixed body (7) fixed to a diffuser (6) joined to the housing (1) at the rear of the impeller (3). The impeller (3) further includes a sleeve (8) having an inner peripheral surface opposed to the outer peripheral surface of the shaft body (2) through a minute clearance and front and rear end faces opposed to the rear end face of the front side fixed body (5) and the front end face of the rear side fixed body (7) through minute clearances, and an impeller (9) joined to the outer peripheral surface of the sleeve (8). The drive mechanism further includes a polar anisotropical permanent magnet (10) enclosed in the sleeve (8) and a rotating field generator (11) enclosed in the housing (1).

A target information storage unit (203) stores information regarding a group of targets (target panels) which are disposed dispersedly on a virtual race course and which each have an objective speed set therefor. An operation input reception unit (201) receives an operation input for a moving object (racing car) to be run on the course. Then, a running condition managing unit (204) manages the running condition of the moving object based on this operation input. Meanwhile, a passage determination unit (206a) sequentially determines whether or not the moving object has passed on the course by contacting the respective targets, based on the managed running condition. Further, a speed comparison unit (206b) compares the speed of the moving object at the time of the passage and the objective speed of each target. Then, an evaluation unit (206) evaluates the operation input from a user based on the determination result and comparison result.
