    摘要: A tocopherol concentrate having a high tocopherol concentration can be obtained in a high yield by subjecting a deodorized distillate formed as a by-product at the step of deodorizing oils and fats to esterification of free fatty acids by addition of an alcohol or removal of free fatty acids by distillation and then to hydrogenation. A tocopherol concentrate can also be obtained by subjecting a deodorized distillate to esterification by addition of a polyhydric alcohol and then to distillation. Concentrates having a high concentration and a high quality can be obtained in a high yield with a good operation efficiency.

    摘要: A coding apparatus generates coded data by coding inputted data in a predetermined unit basis, maps one or more units of the coded data onto a packet of fixed length and outputs the packet. The coding apparatus includes a storage unit that stores the coded data and outputs the data size of the stored coded data, and a packetization unit that maps the coded data stored in the storage unit onto the packet and outputs the header size assigned to the one or more units of the coded data and the payload size of the packet. The coding apparatus also includes a control unit that generates the control information based on the data size of the outputted coded data, the header size and the payload size and outputs the control information, and a coding unit that generates the coded data by calculating an outer candidate value that makes the data size of the coded data to be mapped onto the packet an integral multiple of the payload size of the packet based on the outputted control information and coding the predetermined units of inputted data up to the outer candidate value.

    摘要: A large-diameter-side end surface (104a) of a cotter (104) can be supported by a cotter holder (32) from below through inserting a shaft member (102) along an inner periphery of the cotter (104) from above the cotter (104). In this state, a protrusion (104b) of the cotter (104) and an annular groove (102a) of the shaft member (102) are fitted to each other, and the cotter (104) and a retainer (103) are taper-fitted to each other. Consequently, the cotter is prevented from being unstable, and hence it is possible to assemble the retainer (103) and the cotter (104) to the shaft member (102) with good accuracy.
