Title: Method for controlling proliferation distribution by closed system of organism
Inventor: ONO MASATO
IPC: A01K67/033
Filed: 2001-02-27
Abstract: PROBLEM TO BE SOLVED: To suppress or reduce negative effects caused by introducing an exotic species pollinator in plant culture in using pollination of organism. SOLUTION: In a plant culture, a pollinator is isolated in a closed colony, a diploid male having a sex-determining gene of the same species is made by inbreeding a monoploid male with a diploid male, a substantially sterilized triploid female is made by inbreeding the aforesaid diploid male with a diploid female and a colony for producing the triploid female is delivered to a user. The triploid female flies apart from the colony and does not lay eggs even when it crosses with a male or the possibility of laying eggs is remarkably low. Thus, as the triploid female is solely a first final generation and does not proliferate, so negative effects are greatly suppressed or reduced even though exotic species are introduced as the pollinator.

Title: Control device for power-assisted bicycle
Inventor: HATANAKA KAORU
IPC: B60L15/10
Filed: 2001-02-28
Abstract: PROBLEM TO BE SOLVED: To lightly drive on an inclined road with a same feeling on a flat place with the usage of regenerative power generation and braking. SOLUTION: A traveling resistance determination part 76 energizes a regeneration instruction part 77 when an actual traveling resistance Ra is negative. The regeneration instruction part 77 transmits a regeneration output instruction to a driver 72 of a motor 104 based on driving condition. The driving condition is determined by whether braking operation is conducted or not, or a vehicle speed V is a predetermined value or not. When both of a detected signal Sa outputted in a state that the vehicle speed V is lower than the predetermine value, which is set around a push walk speed, for example, and a detected signal Sb outputted in a state that the incline of the road surface is determined to be downhill based on the actual traveling resistance Ra and a flat traveling resistance R1, are outputted, for example, the regeneration instruction is made to be invalid.  Further, a vehicle speed correspondence calculating part 82 retrieves a coefficient K corresponding to the vehicle speed V on a map. The magnitude of the regeneration output is determined by the coefficient K corresponding to the vehicle speed.

Title: Fluid valve
Inventor: SAEGUSA HIROSHI
IPC: F25B17/08
Filed: 2001-03-01
Abstract: PROBLEM TO BE SOLVED: To surely close a communication port 162, preventing a steam valve from being excessively large, even if the communication port 162 is enlarged. SOLUTION: A valve element 163 is formed into a shell (film), having a curved surface so that a second space B side is projected and the communication port 162 is formed into a conical tapered shape, so that opening area is reduced as going from a first space A side toward the second space B side. As a result, the steam valve 160 can be prevented from being excessively large, even if the communication port 162 is enlarged, because a float is not required. Because the valve element 163 (the curved surface 163a to form the second space B side into a projected shape) is pressed against the conical tapered surface 161a by differential pressure, the communicating port 162 can be closed surely, when closing the valve.
