  • Publication number: 20220258990
    Abstract: A substrate transfer device includes: a traveling unit including a traveling wheel that travels on a rail to transfer a substrate in a first direction; a rail unit including the rail and a rail protrusion protruding from the rail in a second direction different from the first direction; and a sensor unit including a first sensor and a second sensor, wherein the first sensor senses the traveling unit, and the second sensor senses the rail protrusion, wherein the first and second sensors are placed at the same position as each other along the rail on a basis of the first direction.

  • Patent number: 10514424
    Abstract: Disclosed is a system for charge-discharge cycler, particularly to a system for charge-discharge cycler in which a structure of a shunt is improved to improve performance/accuracy of a current control as a key component of an instrument for testing a secondary battery charge-discharge. A system for charge-discharge cycler has the effect of improving the degree of precision/performance of the current control during a charge/discharge inspection of the secondary battery, thereby raising the standard of development/aspect of the secondary battery and developing a charge/discharge performance tester of high performance.

  • Patent number: 9233128
    Abstract: Provided are a composition for stimulating differentiation of MSCs into osteoblasts, which includes cryptotanshinone, and an osteogenesis stimulator including cryptotanshinone and MSCs. When the cryptotanshinone is treated to the MSCs, the differentiation into osteoblasts is stimulated, and thus osteogenesis of a patient may be stimulated by directly transplanting the differentiation-induced MSCs to the patient. Accordingly, the composition or osteogenesis stimulator may be used to treat patients having disability requiring stimulation of osteogenesis such as osteoporosis, bone fracture, bone grafting including alveolar bone grafting for implant placement, or other bone defects.
