Abstract: A gene encoding a polypeptide having an activity to support proliferation or survival of hematopoietic stem cells or hematopoietic progenitor cells is isolated by comparing expressed genes between cells which support proliferation or survival of hematopoietic stem cells or hematopoietic progenitor cells and cells which do not support the proliferation or survival. Proliferation or survival of hematopoietic stem cells or hematopoietic progenitor cells is supported by using stromal cells in which the isolated gene is expressed or a gene product of the isolated gene.

Abstract: A flat type DC motor applicable for disc drive of an electronic still camera in which vibrations of the rotor axle are prevented without increasing manufacturing costs by providing the magnetic field between the stator and rotor to by asymmetrical so that the magnetic attracting force of the rotor to the stator is also asymmetrical. The asymmetrical attracting force causes the axle of the rotor to be urged in the same radial direction relative to the axle bearing in the stator, thus, movements of the axle in radial directions in the clearance between the axle and bearing of the stator are eliminated and the rotor rotates without vibrating.

Abstract: A disc spindle motor of the axial air-gap type includes a record disc chucking portion having a center boss with a disc support surface formed around the center boss. A magnet is arranged adjacent and beneath the disc support surface to hold a magnetic central core of the record disc against the support surface. The rotor of the spindle motor has a rotor magnet affixed to a rotor yoke and facing the stator coils. The center boss and disc support of the disc chucking portion and the rotor yoke of the rotor are all integrally formed in one piece by molding a resin, such as nylon-6, with a magnetic powder, such as iron powder.

Abstract: A binding lace for a novel automatic binder developed by the present inventors is disclosed. The binding lace is continuously thrusted from only one side of the binding lace into a lace guide positioned around an object to be bound and then travels while sliding along the lace guide without buckling to form loops of several turns overlapping each other. During travelling, the binding lace is sent in the lace guide without standing still, due to the properties of an outer portion and a core portion of the binding lace, while the binding lace always expands elastically outwardly in radial direction of the lace guide due to the larger rigidity and tensile stress of the core portion to hold a looped configuration with the loops having substantially the same diameter as the lace guide. After travelling stops, the binding lace is capable of holding the same diameter of the loops and a tip portion of the binding lace is held in the neighborhood of the overlap of the loops.

Abstract: An automatic binding device or binder for binding a long material such as a bundle of electric wires with a lace by actuating the mechanisms associated therewtih according to pilot signals produced when the lace passes through the mechanisms. In this respect, a lace used should afford given rigidity and flexibility. This binder includes a guide member which may be opened and closed, and is formed with guide channels running along its inner peripheral surface for guiding a lace for use in binding. The guide member is formed with a lead-in hole for a lace on one side and a lead-out hole on the opposite side. For smooth guiding of a lace through guide channels, there is used a reversibly rotatable roller mechanism or a combination of the roller mechanism with a vibrating mechanism for vibrating a lace being guided through the guide channels. The lace paid out through the lead-out hole from the guide member is gripped by a lace gripping mechanism on the tip portion of the lace.
