  • Patent number: 11930810
    Abstract: Provided is a cryopreservation container that prevents confusion of specimens to be used for treatment and that is suitable for individual management of fertilized eggs and the like to be cryopreserved. IC tags are attached to a cryopreservation tank 61, a canister 51, a cane 41, and cryopreservation containers such as an ovum storage container 1 and sperm storage containers 71, 81. The cryopreservation containers may also have individual identification codes attached hereto. An ovum storage container 11 is configured by fitting an IC tag 12 from the rear end of a rod-like part 2 of a conventional ovum storage container 1. In addition, the IC tag 12 is formed by providing an inlet 15 inside a thin-walled pipe 14 made of a synthetic resin. The inlet 15 may be fixed at both ends by means of fixing members 18, 18 composed of a nonconductive material, or may be integrally molded with a nonconductive synthetic resin material 20.

  • Patent number: 8556005
    Abstract: In a forklift, power is transmitted to a traveling pump and an operating machine pump through a PTO unit provided to an output shaft of an engine along front-rear direction of a vehicle body. The traveling pump is disposed to a first face of the PTO unit facing the hydraulic motor. An input shaft of the traveling pump is offset from the output shaft of the engine. The drive shaft of the hydraulic motor is offset from the output shaft of the engine and the input shaft of the traveling pump. The hydraulic motor is side by side with the traveling pump. The operating machine pump is mounted to a second face of the PTO unit mounted with the engine. An input shaft of the operating machine pump is offset from the traveling pump. The operating machine pump is under the engine to be side by side with the engine.
