Title: Natural circulation reactor
Inventor: HIDAKA MASATAKA
IPC: G21C15/26
Filed: 1987-11-04
Abstract: PURPOSE:To increase naturally circulating flow of cooling water and improve steam carrying preventing capacity to a reactor core by attaching a baffleplate in the arrangement where flow passage area is reduced as climbed along the whole circumference of the upper end of a shroud upward. CONSTITUTION:Cooling water flowing on the outside of a shroud 3 is fallen together with the cooling water flowed in from a water feed tube 7 and flowed in a reactor core 2 from its lower part. Steam produced in the reactor core 2 is climbed in the shroud 3 together with the cooling water and reaches a baffleplate on the upper end of the shroud 3. Since the more upward flow passage area is, the less it is, the steam and the cooling water increases their velocities and flows out in an upper part of the baffleplate 4. At that time steam bubbles are also combined. The greater part of the steam is separated from the cooling water by inertia force caused by the flow velocity increasing effect of the baffleplate 4 and reaches a dryer 5. The cooling water containing the steam bubbles is flowed on the outside of the baffleplate 4. At this time the flow velocity of the cooling water is lowered and the steam bubbles accompanied with the cooling water are separated by buoyance upward. Therefore, steam carrying-under to the reactor core 2 can be prevented and naturally circulating flow can be increased.

Title: Liquid crystal display device
Inventor: KOBAYASHI MICHIYA
IPC: H04N5/66
Filed: 1991-10-24
Abstract: PURPOSE:To realize a stable and high-quality image display while resolving the problem of a flickering display screen and to provide a simple-construction and low-manufacturing cost liquid crystal display device. CONSTITUTION:The final output stage of an output buffer to be used for a scanning line driving circuit adopts constant current source load type inverters 211 and 212, and the waveform of a scanning pulse VY at its rise time is made sharp and that of a scanning pulse VY at its fall time is made gentle. Accordingly, since the scanning pulse gently and gradually falling down can supply electric charge to a floating capacity CGS, within the switching element of the liquid crystal display element during the gentle falling down of voltage, the part of the electric charge to be applied to the liquid crystal can be prevented from being deprived by the floating capacity CGS. Thus, the level shifting of the liquid crystal application voltage generated can be suppressed.

Filed: 1989-10-27
Abstract: PURPOSE:To eliminate necessity for restarting or exchanging a fuse and to protect a switching element without fail by providing a pulse control means composed of a maximum loss setter, subtracter, function generator, pulse width setter and adder. CONSTITUTION:A voltage Vce of a connecting point between a load 1 and a switching SW element 2 is multiplied with a current Ie flowing to the element 2 by a multiplier 4 and the product is outputted to a computing element 5 and averaged. Next, a subtracter 7 subtracts a calculated value P of an average loss from a set value Pmax for the maximum loss of the element 2 to be applied from a maximum loss setter 6 and outputs a voltage Epi. When the voltage Epi is positive, a function generator 8 outputs a voltage E of a fixed value and when the voltage Epi is negative, the function generator 8 outputs the proportional voltage E. Then, the output voltage E is added with a set voltage Vpwm to indicate maximum pulse width applied from a pulse width setter 9 in an adder 10 and a voltage Ek is outputted. Thus, corresponding to the value of the voltage Ek, a pulse signal Ep to control conducting time is outputted from a pulse generator 11 to the element 2 and the conducting time is shortened at the time of the over load, etc. Then, the loss is suppressed less than the set value and the element can be protected without fail.

Title: Two-dimensional electron source device
Inventor: MORI KUNIYOSHI
IPC: H01J37/26
Filed: 1991-10-25
Abstract: PURPOSE:To form an electron image accurately in a uniform pattern or in a prescribed pattern. CONSTITUTION:UV light from an UV light source 2 is radiated uniformly to a UV transmittable glass 4 arranged on the left end of a vacuum container 3. A MCP(micro channel plate) 5 in the vacuum container 3 generates a large number of electrons multiplied by receiving incidence of both the UV light passed through the UV transmittable glass 4 and photoelectrons generated here. These electrons form a uniform electron pattern immediately after the MCP 5. These electrons are focused by means of a focus electrode 7 and are made incident uniformly upon the surface 8 to be measured after being accelerated by means of an acceleration mesh electrode 6. As a result, a two dimensional uniform electronic pattern is formed on the surface 8 to be measured. In the case where this two-dimensional electron source device is used in an inspection device, an emissive condition and so on the surface 8 to be measured such as a fluorescent surface illuminated by means of the two-dimensional electronic pattern can be observed by means of a SIT camera 9. If the emissive condition of the surface 8 to be measured is not uniform, it follows that defects are caused in that part.
