Title: Heat exchanger and heat exchange method as well as sodium-cooled fast breeder reactor plant applying them
Inventor: TODA MIKIO
IPC: G21D1/00
Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To limit the generation place of a sodium-water reaction to the inside of a heat exchanger tube even when a leakage is generated in the heat exchanger tube and to prevent the expansion of the reaction by a method wherein a pressure on the side of sodium is made higher than a pressure on the side of water. SOLUTION: When a leakage is generated in the heat exchanger tube 14 of a heat exchanger, a leak inflow is generated to the side of low-pressure water from the side of high-pressure sodium, the sodium creeps to the inside of the heat exchanger tube 14, and a sodium-water reaction is generated on the inside of the heat exchanger tube 14. Thereby, a region in which the sodium- water reaction is generated is limited to only the heat exchanger tube 14 in which the leakage is generated. As a result, the amount of a reaction product with generated hydrogen gas is reduced. Thereby, the constitution of a plant is simplified, and the safety of the plant can be increased.

Title: Temperature control device of cooking
Inventor: AMANO TSUNEHISA
IPC: F23N5/14
Filed: 1991-08-27
Abstract: PURPOSE:To perform a cooking operation at a temperature suitable for boiling by a method wherein as a sensing temperature of a temperature sensor reaches a predetermined temperature region, a temperature gradient is detected, and as a cooked item is judged as a boiled one, a reference temperature is detected in reference to its subsequent temperature gradient and upon reaching a completion temperature, the heating is stopped. CONSTITUTION:The temperature gradient (t) of each of predetermined temperatures TA to TB is detected by a temperature sensor 6 through a gradient sensing part 16. The temperature after being detected is judged whether it is more than a predetermined value or not. If the temperature is more than the predetermined value, a cooked item is judged to be a boiled item. After judgement of boiled item, moisture content in a pan 9 evaporates, a temperature gradient of the sensor 6 becomes relatively flat. If the temperature of the sensor 6 exceeds the predetermined temperature, a temperature at a minimum temperature increasing gradient subsequent to the former operation is set at a criminal gradient sensing part 18 as a reference temperature T. A boiling completion temperature TE is calculated at a completion temperature setting part 19 and as a temperature of the sensor 6 reaches a boiling completion temperature TE of the sensor 6 at a solenoid valve control part 20, a gradient sensing is carried out for a specified period of time, a solenoid valve 14 is closed to stop combustion at cooking burners 2 and 2. Then, it is possible to prevent scorching of boiling item.

Inventor: SEKIMOTO NAOHARU
IPC: B60B7/12
Filed: 1981-12-25
Abstract: PURPOSE:To improve resistance to creep and prevent falling of a cap at the time of forming a hat-shaped wheel cap made of synthetic resin by setting an elastic ring-shaped frame member in a space for forming a cap opening end of a metallic mold core before making injection molding. CONSTITUTION:In a space 23 to form therein an opening end of a wheel cap 1 at a joining part of cores 21, 22 of a for injection forming mold, an almost rectangular bench 26 is provided in a flang bottom forming part 25 of the wheel cap 1, and the elastic ring-shaped frame member 10 is set there so as to be prevented from its lateral slide by means of a pair of pins 27. Subsequently, injection molding is performed. Thus, the frame member 10 is buried and formed as one body in the flange of the wheel cap 1, and a part opposite to the bench 26 is formed like a window so as to allow visual recognition of the frame member 10. Due to such a configuration, the ring-shaped frame member 10 prevents inward deformation of a side wall of the wheel cap to improve resistance against creep, and falling of the wheel cap may be prevented.

Title: Video signal processor unit
Inventor: NAGOYA TETSUO
IPC: H04N9/896
Filed: 1988-08-30
Abstract: PURPOSE:To reduce the capacity of a time base correction memory and to lower the operating frequency by inputting a sampling frequency M to the time base correction memory while converting the frequency into a sampling frequency N with a relation of M:N in an integer ratio and M>N after an input video signal subjected to FM modulation is digitized and demodulated. CONSTITUTION:An input video signal 1 in the RF band before FM demodulations is A/D-converted by an A/D converter 2, demodulated by a digital FM demodulator 3, the sampling frequency is lowered by a sampling frequency converter 4 and the signal is fed to a time base correction memory 7. Thus, in comparison with the method where the input video signal at the RF band is A/D-converted, the signal with the sampling frequency without any modification is supplied to the time base correction memory, the quantity of data inputted to the time base correction memory 7 is reduced by the lowered sampling frequency to save the capacity of the memory 7. Moreover, the operating frequency for circuits after the sampling frequency converter 4 is lowered.

Abstract: PURPOSE: To improve the strength of a too wall center part with which the shaft end of an engine valve is brought in contact, by making the density of the center part of the top wall with which the shaft end of the engine valve is to be brought in contact in a tappet main body composed of the top wall and a cylindrical body part higher than the density of the other part. CONSTITUTION: A tappet main body 1 is composed of a top wall 2 and a cylindrical body part 3, and a bottom provided holding hole 4 into which a shim for adjusting the valve clearance is to be fitted is formed on the upper surface of the top wall 2. A round recessed part 5 is formed on the upper surface center of the top wall 2, and a downward projecting part 6 is formed on the lower surface center, and the projecting part 6 is to be brought in contact with the shaft end of an engine valve 7. The tappet main body 1 is formed by the powder metallurgy method, namely, the sintering, and the projecting part 6 with which the engine valve 7 is to be brought in contact has the density higher than that of the other part.  Since the strength of the center part of the too wall with which the shaft end of the engine valve to be brought in contact is increased, the compressive strength resistance of the part is enhanced, and the generations of a recess and abrasion are restrained to the minimum extent.

Title: Embedding bolt for sleeper
Inventor: TANIGUCHI RYOICHI
IPC: E01B9/14
Filed: 1995-08-24
Abstract: PROBLEM TO BE SOLVED: To obtain an embedding bolt for sleepers having a longer fitting life of the screw nail than the case that a screw is directly driven into a sleeper to fix a rail or a tie-plate on the sleeper, by forming a male screw at the outer peripheral face of a metallic cylindrical body and also forming a female screw at the inner peripheral face thereof. SOLUTION: A male screw 11 and grooves 13 are formed at the outer peripheral face of a metallic cylindrical body and a female screw 12 is formed at the inner peripheral face thereof and further, a square hole 14 is formed at one opening thereof. The embedding bolt 1 is prevented from detaching itself from a sleeper by the male screw of the outer peripheral face after it has been embedded and the screw nail can be easily detached because the screw nail is screwed in the female screw 12. Since the embedding bolt for sleepers is made of a metallic cylinder, a permanent set in fatigue in the screw part, brought by the load and vibration on passing of trains is little and hence, the additional fastening interval of bolts becomes longer.  In this way, the fitting life of screw nail can be prolonged in comparison with the fixing case that a rail or a tie-plate is fixed to a sleeper by directly driving screws into the sleeper.

Title: Learning method for roll profile
Inventor: ISHIHARA YOSHIAKI
IPC: B21C51/00
Filed: 1986-09-16
Abstract: PURPOSE:To obtain a rolling reduction schedule having a high accuracy and stability by setting lower a corrective learning rate between paths in the stage of correcting the profile value for a shape control based on a plate crown error calculated by a measured plate thickness. CONSTITUTION:The plate thickness is measured by a gamma rays detector 6 to input into a roll profile separating analyzer 5 to separate into a measured thickness of each position on the width direction and a measured plate crown (25, 26). By comparing this measured thickness and a predicted plate thickness hx calculated through a gauge-meter model, a plate thickness error  Tx is calculated 27, simultaneously, a plate crown error  Cr is calculated 28 by a ratio crown change. By using the calculated plate thickness error  Tx and the plate crown error  Cr, a correcting value of the roll profile is calculated. In this case, a high learning rate alpha28 set previously is used to calculate the roll profile correcting value in a real time and as for the correction of the roll profile for the shape control, the roll profile correcting value is calculated 31 by a low learning rate beta30 set previously. In this way, a disturbance for shape controlling caused by an error of the thickness detector itself is eliminated.
