Title: Boiling water nuclear reactor
Inventor: SATO TAKASHI
IPC: G21C1/08
Filed: 1987-09-29
Abstract: PURPOSE:To control a natural circulation flow rate and to control a reactor output with controlling control rods and a core flow for a boiling water nuclear reactor, by controlling an openness of an control valve fitted to a steam riser tube or a steam downcomer tube. CONSTITUTION:A downcomer 8 is connected to a steam drum 5 and, to downcomer 8, a control valve 10 is fitted. In case a reactor output is diminished in accordance with a diminished power demand during a night time, a coolant flow resistance in the downcomer 8 increases by decreasing an openness of the control valve 10, therewith a downcoming flow is diminished. The coolant flow rate flowing into a core 1 decreases, a coolant boiling ratio inside the core 1 rises, consequently the coolant which has also a role of a moderator decreases its in-core existence ratio. Through this procedure, a natural circulation flow rate is limited and the reactor output is controlled by control rods 9 and the core flow rate.

Title: Electromagnetic clutch for car compressor
Inventor: OOTA MASAKI
IPC: F16D27/112
Filed: 1983-12-22
Abstract: PURPOSE:To absorb a shock when a clutch is connected by providing a secondary clutch disk, which is brought in contact with a primary driven clutch disk by means of rotating centrifugal force, to increase the adsorbing force between said primary driven clutch disk and a driving clutch member, on a power transmission member. CONSTITUTION:Centrifugal force, which acts on a secondary driven clutch disk 17, becomes larger, as the speed of rotation of a compressor rises, and the driven clutch disk 17 is liable to jump out in the radial direction against the elasticity of an elastic support board 16, but is moved toward a primary driven clutch disk 14 due to the restraint of said support board 16. When the secondary driven clutch disk 17 approaches, the primary driven disk 14 adsorbs the secondary clutch disk 17 by means of its leakage flux. Accordingly, the magnetic path of the primary driven clutch disk 14 is increased and, thereby, a clutch is prevented from slipping, carrying out complete transmission of torque.
