Title: Fast reactor
Inventor: SEKIGUCHI MINEO
IPC: G21C15/18
Filed: 1994-08-25
Abstract: PURPOSE: To form a natural circulating flow of coolant when a reactor is stopped, and increase the heat removing quantity by providing each passage for normal flow and back flow on a shielding assembly charged on the circumferential area of a core. CONSTITUTION: At general operation of the reactor, a coolant having a small flow rate to a fuel assembly 16 flows in a &shielding assembly 21 from a low pressure plenum 10 to an upper plenum 4 through a low pressure passage and a not-mat flow passage. When the reactor is stopped, the coolant heated by the decay heat of a core 1 is raised from the assembly 16 inner part to the plenum 4 through a clearance part 35. The coolant partially gets into a heat exchanger 15 through a coolant inlet port 17 and flows out from a coolant outlet port 18, and partially descends 19 in the plenum 4. These coolants descend in the back flow passage of the assembly 21 and flow out to the core 1 peripheral part through the outlet.  On the other hand, the coolant in the core 1 center part is heated and raised, and the outflown coolant is sucked into the core 1 center part this ascending flow, and raised in the clearance part 35. Thus, a natural circulating flow of coolant by way' of the assembly 21 is formed, and the decay heat removing quantity is increased.

Title: Antenna switching system
Inventor: HAYAKAWA MASATO
IPC: H04B5/02
Filed: 1999-08-06
Abstract: PROBLEM TO BE SOLVED: To provide an antenna switching system for reducing influences caused by noise induced by a cable by performing control to stop the transmitting operation and/or receiving operation of an R/W device from the selection start of an antenna to the selection end. SOLUTION: Antennas 1a-1d are respectively connected with a switching part 2 and the switching part 2 is connected with an R/W device 3. After the transmitting/receiving operation of the R/W device 3 is stopped, a control part 4 starts switching of the switching part 2 soon. While switching is performed by the switching part 2 and for a while after switching completion, control is performed so that the R/W device 3 can continuously stop the transmitting/ receiving operation. After the lapse of a predetermined stop period, the transmitting/receiving operation of the R/W device 3 is started again. Concerning such a stop period of transmission/reception, a period sufficient for completely normalizing an unstable state is previously stored by the control part 4. Thus, the influence caused by the unstable state can be avoided.

Title: Tape processor and tape printer therewith
Inventor: KAMIJO NORIYUKI
IPC: B65H41/00
Filed: 1997-08-05
Abstract: PROBLEM TO BE SOLVED: To commonly use a device constitution between trim and peel mechanisms, as far as possibly by installing a power transmission means which transmits the power of a single driving means to the trim and peel mechanisms at the same time. SOLUTION: A motor 21 is rotated clockwise by a trim switch 61 being turned on, and it is rotated counterclockwise by a peel switch being turned on the other way. In addition, rotatory power of this motor 21 is bifurcately transmitted to a trim mechanism 22 and a peel mechanism 23 via a clutch mechanism 24. At that time, this clutch mechanism 24 makes a reversible rotation of the motor 21 into being intermittent as a trigger, and thereby when the motor 21 is rotated clockwise, it transmits power to the trim mechanism 22 and the peel mechanism 23, but the motor 21 is rotated counterclockwise, it transmits the power to the peel mechanism alone. When a driving shaft 27 goes into its normal rotation, an output side clutch 42 receives a viscous property of grease and thereby it is dragged.  Accordingly, it collides with an input side clutch as dragging, so that the rotary power of the motor 21 is thus transmitted to the trim mechanism 22.
