Title: Method of producing a mini-potato
Inventor: HOSAKA KAZUYOSHI
IPC: A01H3/02
Filed: 1998-10-30
Abstract: Solanum stenotomum, Solanum phureja and Solanum goniocalyx, which are diploid potatoes native to the Andes, are crossed by open pollination, thereby forming a hybrid population rich in genetic variation. The hybrid population is raised while screening the hybrid population on the basis of selection criteria including a yield thereof, thereby reconstituting the hybrid population. The reconstituted hybrid population is raised for seedlings under short-day light conditions while limiting a rhizosphere thereof and controlling the growth at a slightly lower temperature during a potato-tuber growing period. A mini-potato edible whole (including skin) in one bite can be thus obtained.

Filed: 1997-09-19
Abstract: In  intermittent  reception operation  during a waiting time, PCHs are processed by RF receiver 3, A/D converter 4 and correlator 5, and decoded by decoder 6 to obtain decoded data 7. Intermittent reception control circuit 16 judges the presence or absence of call data in the PCHs based on control information near the start of the PCHs (paging channels) and immediately stops the functions of RF receiver 3, A/D converter 4, correlator 5, and decoder 6, in the case that no call data is found, thus  reducing  power  consumption  in  intermittent reception.  This  extends  the  waiting  time  of  a battery-operated digital radio communication system.
