Title: Mixing process of powder/particle mixture
Inventor: HAYASHI YUTAKA
IPC: B01F5/00
Filed: 1983-03-31
Abstract: PURPOSE:To perform uniform mixing by eliminating uneven distribution of powder component by forcibly dispersing powder-particle mixture in a falling stream with a plural eaves projecting from a feeding port with an interval and a length reaching to almost the central part of the falling stream. CONSTITUTION:An appropriate amt. of enriched rice 10 which has passed through a flow rate controlling plate 23 is discharged from a feeding port 20 of a chute 21 while polished rice 5 is flowed down from the outlet 7 of a hopper 1. The enriched rice 10 is mixed with the polished rice 5 flowed down through the outside peripheral zone of the flowing down stream 12 corresponding to the part of the feeding port where no eaves 24 is disposed, and the polished rice 5 flowed down onto the eaves 24 is dispersed on the upper surface of the eaves 24 and separated to right and left W. The enriched rice 10 discharged from the feeding port reaches the central zone X of the flowing down stream 12 and is combined with the separated streams of the polished rice 5. The mixing is prompted by this way.

Title: Information retrieving device
Inventor: MAEDA TAKESHI
IPC: G11B7/085
Filed: 1985-03-22
Abstract: PURPOSE:To detect accurately the speed of an optical head between high and low levels by applying the track pitch finer than the external scale pitch as a scale when the shift speed of the optical head is slowed down. CONSTITUTION:An access action is started from an access controller 203, and a polarity signal 56 which decides the traveling direction of a linear motor 68 in its radius direction is applied to a polarity switching circuit 209. Thus the motor 68 starts with its maximum acceleration. A speed signal 22 has large ripple in a low-speed range and does not show a correct speed; while a speed signal 227 shows an accurate speed even in a low-speed range. However, the signal 227 does not show the correct value either owing to the limit of the detected frequency characteristics of a track shift signal 407 when the speed is increased. Therefore, these speed signals are switched at the points of their values E1 and E2 within the range where the signal 226 is stable and at the same time within the range where the signal 226 is stable and at the same time the signal 227 has the correct value. In such a way, the speed signals obtained by an external scale and a track scale are selected in response to the shift speed. Then a stable speed detecting signal is obtained.

Title: Distance relay
Inventor: UKAWA TETSUO
IPC: H02H3/40
Filed: 1990-03-07
Abstract: PURPOSE:To reduce detection error by employing an amplifying circuit producing output having different magnitude according to the input at the time of three-phase short circuit fault or two-phase short circuit fault in a single distance relay protecting both three-phase and two-phase short circuit faults. CONSTITUTION:In a single distance relay protecting both two-phase and three- phase short circuit faults, a three-phase vector difference current is rectified and smoothed to produce an operating amount while respective three-phase voltages are rectified and combined to produce a suppression amount. The vector difference current is fed through a full-wave rectifying circuit 12, a combining circuit 13, a maximum value detecting circuit 14 and a smoothing circuit 15 to an amplifying circuit 17 which then produces an operating amount. The amplifying circuit 17 employs an operational amplifier 29, where the input impedance comprises a parallel connection of a resistor 26 and a capacitor 27 whereas a feedback impedance comprises only a resistor 28. In other words, the amplifying circuit 17 exhibits a high amplification factor for higher harmonics. Consequently, the content of low order harmonics is high in the single-phase full waveform at the time of two-phase short circuit and thereby under reach is eliminated.

Title: Heat exchanger
Inventor: SHIMIZU TAKEO
IPC: F28D1/06
Filed: 1980-04-30
Abstract: PURPOSE: To prevent leakage of fluid to be cooled or heated in a nuclear reactor remaining heat removing system for an atomic power plant, by filling a heat exchanger with a liquid having a pressure higher than that of said fluid.  
     CONSTITUTION: Into a barrel 5 of a heat exchanger is filled a liquid 6 having a pressure higher than that of a fluid to be heated or cooled using a continuously pressuring apparatus 7. Accordingly, if a heat conductive tube 2 for the liquid to be cooled or heated happens to have a hole or the like, the liquid 6 whose pressure is higher than that of the fluid in the heat conductive tube 2 will flow into the heat conductive tube 2, and therefore the fluid 1 cannot leake outside of the tube 2. Thus, leakage of the fluid to be cooled or heated can be prevented.

Title: Ultrasonic flowmeter for intake air in internal combustion engine
Inventor: NOMURA TOSHIO
IPC: G01F1/66
Filed: 1982-04-07
Abstract: PURPOSE:To reduce errors, by providing a soundproofing wall or a partitioning wall between the ultrasonic wave propagating paths of two oscillating loop systems provided in a pipe, thereby preventing noises and erroneous counting. CONSTITUTION:The two soundproofing walls 24 and 25 are provided in approximately in parallel with the flowing direction of fluid in the pipe 1, so that the first ultrasonic wave propagating path between an ultrasonic wave transmitter 2a and a receiver 3a and the second ultrasonic wave propagating path between an ultrasonic wave transmitter 2b and a receiver 3b are separated. It is desirable that the soundproofing walls 24 and 25 are made of a sound absorbing material. Owing to the presence of the soundproofing walls 24 and 25, the ultrasonic wave irradiated from the transmitter in one oscillating loop system does not reach the receiver in the other oscillating loop system through the fluid in the pipe 1. The interference of the ultrasonic waves between both oscillating loop systems can be also prevented.

Title: Steam turbine controlling equipment
Inventor: KAMIDATE FUMIO
IPC: F01K23/10
Filed: 1985-03-20
Abstract: PURPOSE:To smoothly obtain an initial load, which is constantly kept at a fixed value, by controlling a steam control valve, which is related to a steam turbine driven by the steam generated by using the waste heat from a gas turbine, based on the front steam pressure of the steam control valve at the time when a steam turbine generator is put into the electric power system. CONSTITUTION:When a steam turbine generator in a combined plant is put into the electric power system, a signal from a put-in signal generating part 25 changes the output from one-shot pulse generator 26 into ON for only an instant, and it further changes the output from an OR-circuit computing element 29 into OFF. Accordingly, the output from an FF circuit 32 turns ON, while the output from a rate-of change limiter 23 varies at a predetermined rate of change from the command-value given by an opening commanding part 23, which is located just in front of the limiter 23, toward a target value computed by a function generator 22 in accordance with the front steam pressure of a steam control valve 7, which is measured by a steam pressure measuring instrument 21. As a result, the opening of the steam pressure control valve 7 is controlled by the output from the steam-pressure rate-of-change limiter 23 and is gradually opened toward the above-mentioned target value.

Title: Low-temperature storage tank
Inventor: OOTSUKA HIROICHI
IPC: F17C3/04
Filed: 1978-05-15
Abstract: PURPOSE:To insure safety for an intersecting wall type low-temperature storage tank against all cases by fitting an elastic bracket on the side of the intersecting wall by means of a short anchor bolt. CONSTITUTION:In this low-temperature storage tank, elastic bracket 7 is fitted to intersecting wall 5 under the condition of compression by means of anchor bolt 8, which is shorter than the gap between this intersecting wall 5 and inner tank wall 2. For this reason, even if inner tank wall 2 is displaced by the amount of delta due to the operation of the storage tank, elastic bracket 7 fills the gap between intersecting wall 5 and inner tank wall 2. Even if a breakage occurred on intersecting wall 5, perlite particles 3 filled in the gap between intersecting wall 5 and outer tank wall 1 are obstructed by the above-mentioned elastic bracket 7 and do not flow into the gap between inner tank wall 2 and intersecting wall 5. As a result, no sinking phenomenon takes place.
