Title: Low noise amplifier
Inventor: TANIGUCHI ADO
IPC: H04B1/16
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To provide a low noise amplifier low in cost, simple in structure, reduced in the number of sheets of boards and stable in performance by mounting a low noise amplifier element and a matching circuit on a sheet of synthetic resin board in addition to a high frequency amplifier part and a power supply part. SOLUTION: An amplifier part 5 and a power supply part 7 are mounted on a glass epoxy board 9 in addition to a high frequency trap part 1, a changeover switch 2, a BPF 3, a protective limiter 4 and an attenuator 6. The received signals S1 which are inputted to a terminal 10 through an antenna AT are inputted to the BPF 3 via a capacitor 13 and the switch 2. The BPF 3 transmits the signals S1 of necessary frequency bands and eliminates the unnecessary frequency to output these signals to the part 5. At the part 5, the amplified output signals are adjusted by the attenuator 6 and then outputted through a terminal 11 as the receiving signals S2. Meanwhile, the transmitting signals S3 which are inputted to a terminal 12 pass through a DC blocking capacitor 14 and outputted to an antenna through a terminal 10 via the switch 2.

Title: Two-phase reactor plant having partitioned separation condenser
Inventor: MAABIN MANWAI FUI
IPC: G21C15/18
Filed: 1992-07-13
Abstract: PURPOSE: To obtain a small separation condenser in which the stability f flow is improved by separating a condenser into a distribution plenum and a collection plenum communicated through a manifold and arranging the tube of manifold in a cooling liquid pool thereby coupling both plenums with a reactor vessel through a duct. CONSTITUTION: When a turbine is separated, steam from a vessel 106 ascends through ducts 134, 220 and then it is stored in a distribution plenum 216. The steam stored in the distribution plenum 216 is passed through pipes 230, 232 and partially condensed into water with thermal energy being transmitted to a pool 125. Condensed liquid flows into a collection plenum 218 thence flows back into the reactor vessel 106 through a base opening 224 and a duct 136. Uncondensed gas is not liquefied but stored above the collection plenum 218. Under a state where the uncondensed gas is generated sufficiently for disturbing the operation of a condenser 200, a valve 140 is opened and the uncondensed gas can be released to a wet well 126.

Title: Exposure device for fluorescent screen formation
Inventor: MAEDA SHIYOUICHI
IPC: H01J9/227
Filed: 1981-11-18
Abstract: PURPOSE:To suppress the shift of points upon which beams become incident, which might be caused due to the shift of a shadow mask or the like, at a low cost by locating the longitudinal direction of a discharging emissional part  parallel to an axis which slants from the vertical axis of a face panel by a  rotation angle, theta. CONSTITUTION:An ultra-high pressure mercury lamp 5 is located in such a manner that its slender discharging emissional part 10 is positioned parallel to an axial line (l-l') which slants clockwise from the vertical axis (Y-Y') of a face panel 4 by a rotation angle (theta). As a result, the outgoing point of the light of the lamp 5 seen from the lower surface side of a correction lens system, especially from its peripheral part, shifts clockwise from that seen when the part 10 is not given any slant of the rotation angle (theta). Therefore, exposed points, points of a photosensitive film provided on the inner wall of the face panel 4, especially of its peripheral part, upon which exposure beams become incident through a shadow mask, shift in directions indicated by the arrows. Consequently, any shift of the exposed points, which might be caused when the points upon which the beams are incident upon shift, can be prevented.

Title: Controller for cooling fan
Inventor: MAKIZONO KAZUYA
IPC: F01P5/02
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To prevent hot air from making reverse flow in a condenser so as to reduce consumption power of a compressor by driving a cooling fan when a coolant discharging rate of the compressor is not more than a predetermined rate, and vehicle speed detected by a car speed detecting means is under a predetermined speed, in a condition in which a refrigerating cycle is driven. SOLUTION: It is judged whether an air conditioner is in a driving condition from an ON/OFF condition of a start switch or not during operation of a vehicle. When the air conditioner is stopped, it is judged that a water temperature detected by a water temperature sensor 11 is not less than a predetermined temperature (about 90 deg.C) T1 or not. In the case of 'YES' in the judgment, a fan 5 is driven with the maximum air capacity. In the case of 'NO', the fan 5 is stopped. In the case of an electromagnetic clutch 7 is in an OFF state and when the air conditioner is in a driving condition, it is judged whether speed detected by a vehicle speed sensor 12 is not less than predetermined speed or not. In the case of 'YES' in the judgment, the fan 5 is stopped.  In the case of 'NO', the fan 5 is driven with a minimum air capacity so as to prevent hot air heated by a radiator 3 from making reverse flow in a condenser side.
